Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a pipe holder, and more specifically, for holding pipes such as fuel tubes and brake tubes under the floor of automobiles, in engine compartments, etc. This invention relates to pipe holders that are required to be strong enough to withstand external impacts such as so-called flying stones.

(Prior Art) An example of such a conventional pipe holder is shown in FIG. 7. This pipe holder uses an engagement protrusion 2 and a rotation prevention protrusion 3 so as to cover a predetermined part of a synthetic resin clamp member 1 (the part that becomes the bottom side when attached to an automobile). Metal protector 4 to prevent flying stones.
It is assembled with.

Then, while holding an appropriate number of pipes 5 with the clamp member 1, a tightening bolt 6 made of metal in consideration of impact resistance is inserted through the hole 7 provided at one end of the protector 4, The pipe 5 is attached to the body panel by screwing and tightening the bolt 6 into a weld nut 9 of a bracket 8 welded to the body panel (not shown).

In some cases, a bolt is welded to the bracket 8, and the bolt is inserted into the hole 7 and tightened with a metal nut (not shown).

(Problem to be Solved by the Invention) However, with the above-mentioned conventional pipe holder, when installing it to the body panel, the pipe 5 and protector 4 are held in one hand and supported at the installation position, and at the same time,
The bolts 6 and nuts for tightening must be fitted into the impact wrench sockets in advance.

As a result, workability is poor. Particularly in the process of installing pipe holders arranged in a line, there is a problem that the tightening work using an impact wrench cannot be carried out quickly and continuously, which deteriorates the working efficiency of the entire line.

By the way, as a conventional technique other than the above, an insertion hole for a body-side bolt is provided in a synthetic resin clamp member, and a synthetic resin tightening nut member is temporarily attached at a position facing this hole via a thin joint. There is also a technique in which the pipe holder is integrally molded in the state, or a technique in which the insertion hole provided in the clamp member is provided with a pawl for locking into the thread groove of the bolt so that the pipe holder can be temporarily fixed to the body side bolt. If these techniques can be applied as they are, the above problems can be solved.

However, it is difficult to simultaneously mold the temporarily attached nut member and the locking pawl as described above in terms of die cutting, and the tightening nut member is made of a metal with high impact resistance. etc., it is impossible to integrally mold this with a synthetic resin clamp member via a thin joint.

Therefore, in this invention, a protector made of metal or the like is attached to a clamp member made of synthetic resin, and the tightening member can be rotated when attached to the body of an automobile or the like using a screw-type tightening member made of metal or the like. The problem to be solved is to make it possible to perform the installation work quickly and continuously by integrating the pipe holder in a state where the pipe holder is in a stable state and making it possible to temporarily fix the pipe holder to the body. .

(Means for solving the problem) The pipe holder of the present invention that solves the above problem is
It consists of a synthetic resin clamp member that has a pipe support part into which a pipe can be fitted, and a protector that covers a predetermined part of the clamp member and is made of a material with high impact resistance. An insertion hole is formed in the body into which a protruding bolt can be inserted, and a locking pawl is provided on the inner periphery of the insertion hole that can be temporarily secured to a thread groove of the bolt, and the protector is made of a material with high impact resistance. A tightening nut formed of is rotatably mounted on the axis of the insertion hole of the clamp member, and the protector is prevented from rotating with respect to the clamp member via a rotation preventing means before being temporarily fastened to the bolt. It can be assembled in one piece.

In the above technical means, the "predetermined portion" of the clamp member covered by the protector means:
This is a part that should be protected from external impacts such as flying stones.
Usually, this is the part that will be on the bottom side when it is attached to an automobile, etc., but it may cover a different part depending on the location and direction in which the clamp member is attached to the automobile, etc.

A metal material is usually used as the "material with high impact resistance," but other types of materials with the necessary physical properties can also be used.

(Function) The insertion hole of the clamp member holding the pipe is fitted into the bolt protruding from the body. At this time, the bolt is inserted until its tip contacts the tightening nut attached to the protector, and the temporary fixing claw provided in the insertion hole of the clamp member is engaged with the thread groove of the bolt, causing the pipe to tighten. The retainer is temporarily attached to the body.

Therefore, there is no need to support the pipe holder with one hand when screwing and tightening the nut onto the bolt using an impact wrench or the like, or to fit the nut into the socket of the impact wrench in advance.

(Example) Next, a first example of the present invention will be described based on FIGS. 1 to 5.

The pipe holder 10 includes a clamp member 11 made of synthetic resin and a protector 12 made of metal.

The clamp member 11 has a mounting portion 13 at its center.
It is equipped with An insertion hole 14 is formed vertically through the mounting portion 13, and this insertion hole 14
A locking pawl 15 having a thickness capable of being bent and deformed is projected toward the center from a portion near the opening at the lower end thereof in an obliquely upwardly inclined state. These locking claws 15 are
As shown in FIGS. 3a to 3c, which are views of the main part of the insertion hole 14 in the direction A in FIG.
The bolt 16 is formed in an arc shape around the center of the bolt 4, and is adapted to engage with a thread groove 17 of a bolt 16 inserted into the insertion hole 14.

On both sides of the mounting portion 13, there are seats 1 having an arcuate cross section.
8, and a retaining piece 19 which is thick enough to be flexible and deformable and which protrudes toward the receiving seat 18. In addition, the pipe support part 2
Protrusions 21 for assembly are provided on the outer surface of the wall at both ends of the housing.

Further, the upper surface of the clamp member 11 is formed flat, and ribs 22 that protrude upward are provided along both ends of the clamp member 11 in the transverse direction.

Next, the protector 12 has the pair of ribs 22
A top surface protection section 23 that can be fitted between the clamp member 11 and can cover the flat top surface of the clamp member 11; and a pipe support section 20 that is bent and extended from both ends of the top surface protection section 23 at approximately right angles. It is a plate-like member including an end face protection part 24 having a shape that can cover the outer surface of the wall at both ends.

A metal nut 26 is attached to a stopper hole 25 provided in the center of the upper surface protection part 23. This nut 26 is assembled by inserting the cylindrical portion 27 protruding along one opening of the female thread into the stop hole 25 and pushing it outward with appropriate means.
5 and is rotatably attached to the protector 12.

Further, each of the pair of end face protection parts 24 is provided with an assembly hole 28 that can fit into the projection 21 provided on the clamp member 11.

Then, the protector 12 is placed over the clamp member 11 from above so as to fit between the pair of ribs 22, and the protrusion 21 is fitted into the hole 28, thereby assembling the clamp member 11 and the protector 12. A pipe holder 10 is constructed. Note that at this time, the nut 26 is positioned above the insertion hole 14 in the axial direction.

This embodiment is constructed as described above and is used as follows.

That is, as shown in FIG. 4, a pipe 29 such as a fuel tube or a brake tube is first assembled into the pipe holder 10 by pushing it into the pipe support section 20. Then, the insertion hole 14 of the mounting part 13
is fitted to a bolt 16 fixed to a body panel 30 such as the underside of a floor of an automobile by welding or implantation. By this operation, the tip of the bolt 16 is inserted to the position where it abuts the nut 26 attached to the protector 12, and the locking pawl 15 is inserted into the nut 26 attached to the protector 12.
- The pipe holder 10 is temporarily fixed to the body panel 30 at the position shown in FIG. 4 in order to engage with the thread groove 17 of the bolt 16 as shown in FIG. 3c.

Then, use an impact wrench etc. to tighten the nut 2.
6 onto the bolt 16 and tightening, the installation is completed as shown in FIG. At this time, the protector 12 is prevented from freely rotating relative to the clamp member 11 due to the fitting action between the protrusion 21 and the hole 28 and the restricting action of the ribs 22 on both sides, so that the assembled state of the clamp member 11 is maintained.

Therefore, it is not necessary to support the pipe holder 10 or the pipe 29 with one hand when operating the impact wrench. Furthermore, there is no need to fit a tightening nut into the socket of the impact wrench in advance. Therefore, the efficiency of the installation work of the pipe holder 10 is high. In particular, the lined pipe holder 10
In the installation process, each pipe holder 10
After bringing them into the temporarily attached state shown in FIG. 4, they can be tightened one after another to the attached state shown in FIG. 5 by continuous operation of an impact wrench, thereby significantly improving work efficiency.

After installation, the synthetic resin clamp member 11 is effectively protected from flying stones by the protector 12, and since the tightening nut 26 is also made of metal, it can withstand impacts from flying stones and the like.

In this embodiment, the mounting portion 13 does not necessarily need to be provided at the center of the clamp member 11.
Furthermore, the number of pipe support portions 20 formed is not limited to that shown in the drawings. If the engagement between the protrusion 21 and the hole 28 sufficiently prevents separation and relative rotation between the clamp member 11 and the protector 12, the rib 22 is not necessary.

Next, a second embodiment of the present invention will be described based on FIG. 6.

The synthetic resin clamp member 31 of this embodiment is provided with a pair of assembly ribs 32 along the central portion on its upper surface in the longitudinal direction. These ribs 32 reach the outer surfaces of the vertical walls of the pipe support sections 33 on both sides that can support a plurality of pipes, respectively. Therefore, the ends 34 of the ribs 32 are directed downward.

On the other hand, the metal protector 35 is formed into a bent plate shape capable of covering the upper surface and both longitudinal side surfaces of the clamp member 31, and can be fitted onto the rib 32 along the central portion in the longitudinal direction. It is provided with a groove 36 for assembling the shape.

The clamp member 31 and the protector 35 elastically expand the protector 35 to form a groove 36 in the rib 32.
Since the ribs 32 are assembled by fitting and the ends 34 of the ribs 32 face downward, they will not separate.
Further, even when the nut 37 of the protector 35 is tightened, the clamp member 31 and the protector 35 do not shift in the rotational direction.

The configuration, operation, and effects of other points in this embodiment are the same as those in the first embodiment.

(Effects of the invention) This invention is a clamp member made of synthetic resin with a protector made of a material with high impact resistance, and is suitable for mounting on the body of an automobile etc. using a nut made of a material with high impact resistance. To enable rapid and continuous operation of a tightening tool by eliminating the trouble of supporting a pipe or a pipe holder by hand or previously fitting a nut into a tightening tool such as an impact wrench.

Therefore, the workability of assembling the pipe holder is improved. In particular, work efficiency in lined assembly processes is significantly improved.

In addition, since the protector is integrally assembled to the clamp member in a rotation-prevented state via the anti-rotation means before being temporarily fastened to the bolt, the clamp member and the protector can be connected to each other by tightening the nut to the bolt. The protector can be fastened to the body of the protector at the same time, and the assembly work is simpler than when attaching the protector to the clamp member later.

Further, since the protector is fastened together with the clamp member to the body of an automobile or the like using the nut, the protector and the clamp member can be firmly assembled to the body.
