Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a pipe holder, and more specifically, the present invention relates to a pipe holder. This product relates to a pipe holder for attaching to the bottom surface or panels that make up the engine room.

(Prior Art) Conventionally, there is a pipe holder 1 made of synthetic resin as shown in FIG. 7, for example.

This pipe holder 1 has a bolt insertion hole 4 in a holding member 3 capable of clamping a pipe 2, and a base opening of the bolt insertion hole 4 to enable preliminary inspection of the piping of the pipe 2. A locking pawl 5 for temporary fixing is provided, and a flange 7 provided on a nut 6 for permanent fixing that can be fitted into the bolt insertion hole 4 allows the holding member 3 to be attached to the bolt on the body side as shown in FIG. This is the main stop.

(Problems to be Solved by the Invention) However, in the pipe holder 1 in which the holding member 3 and the nut 6 are constructed separately as described above, manufacturing costs including mold costs and processing costs are high. or,
As a general problem due to an increase in the number of parts, handling during transportation and delivery becomes troublesome, and furthermore, the number of assembly steps increases, resulting in poor workability.

Among the above-mentioned problems, regarding handling and assembly during transportation and delivery, an inward flange 8 for temporary attachment is provided at the opening of the bolt insertion hole 4 as shown in FIG. It is also possible to sandwich the holding member 3 and the nut 6 between the breakable locking protrusion 9 of the nut 6 and the locking pawl 10 for preventing removal, so that the holding member 3 and the nut 6 can be handled in a temporarily attached state. However, in this case, although the structure of the mold for the holding member 3 and the nut 6 is complicated, the above-mentioned structural problem cannot be solved.

Furthermore, there is also a conventional technique in which a nut is temporarily attached and integrally molded into the tip opening of the bolt insertion hole of the holding member via a thin joint. However, in general, when holding multiple pipes with a pipe holder and attaching them to a body panel, the above-mentioned temporary locking pawl 5 is required to perform a preliminary inspection of the piping. It is difficult to integrally mold the retaining pawl 5 and the nut temporarily attached to the clamp member in the axial direction of the bolt insertion hole from the viewpoint of die cutting.

Therefore, the present invention consists of a pipe holding member equipped with a bolt insertion hole, a final fixing nut temporarily attached to the opening at the tip of the bolt insertion hole, and a nut for permanent fixing located at the opening at the base end of the bolt insertion hole. The problem to be solved is to provide a pipe holder that can be integrally molded with a positionable locking claw for temporary fixing.

Another object of the present invention is to provide a pipe holder that prevents the holding member from bending after the holding member holding the pipe is attached to the bolt of the body and has good pipe holding performance. .

(Means for solving the problem) A technical means for solving the above problem includes a pipe support section provided with a seat for a pipe clamp, and a bolt insertion hole that can fit a bolt on the body side. A pipe holder made of synthetic resin, in which a nut for final fixing is connected to the holding member so as to be located at the tip opening of the bolt insertion hole through a thin connecting part, A movable piece that can be folded back toward the proximal opening side of the bolt insertion hole extends from one end via a thin hinge part, and the part of this movable piece that corresponds to the bolt insertion hole has a temporary lock. A bolt insertion hole with a claw is provided.

In the above technical means, the number of seats provided on the pipe support is not limited. When a plurality of seats are provided, these seats may be provided on both sides of the bolt insertion hole, or may be provided on only one side.

The movable piece may be provided with a length substantially equal to the entire length of the holding member, and the movable piece may be configured such that its tip is fixedly engaged with the other end of the holding member. In this case, the movable piece may be provided with a pipe-holding projection that projects toward the pipe introduction portion of the seat. Furthermore, in the case where the seat is provided only on one side of the bolt insertion hole as described above, the movable piece may be small enough to cover only the base end opening of the bolt insertion hole and its periphery. The movable piece does not necessarily need to be able to be fixed to the holding member at the folded position.

(Function) The pipe holder can be integrally formed in a shape in which the movable piece extends laterally from one end of the holding member.

In use, when the movable piece is folded back, the temporary locking pawl is located at the base end opening of the bolt insertion hole. When the distal end of the movable piece is engaged with the other end of the holding member, the movable piece resists the curvature of the holding member that causes the pipe to fall off.

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

The pipe holder 11 is made by integrally molding a holding member 12, a nut 13, and a movable piece 14 using a synthetic resin material.

In the holding member 12, the pipe support parts 15 provided on both sides each have an open pipe introduction part 1.
A seat 17 having an arcuate cross section having a diameter of 6 is formed. A bolt insertion hole 18 is formed in a substantially central portion of the holding member 12 so as to extend vertically through the holding member 12 . The nut 13 is connected to the opening on the tip side (upper side in FIG. 1) of the bolt insertion hole 18 via a thin connecting portion 19 so as to be positioned on the axis of the bolt insertion hole 18. .

The nut 13 is a cylindrical body having an inner diameter corresponding to the root diameter of a bolt 20 to be described later and an outer diameter that can be fitted into the bolt insertion hole 18. A flange 21 and a square head 22 are formed.

On the other hand, the movable piece 14 is a flat member extending from one end of the holding member 12 via a thin hinge portion 23 . The length of the movable piece 14 (width in the left-right direction in FIG. 1) is approximately the same as the length of the holding member 12, and an engaging portion 24 bent at a substantially right angle is formed at the tip of the movable piece 14. There is. Furthermore, a claw 25 is protruded along the tip of the engaging portion 24. In addition, at the other end of the holding member 12,
A pawl 26 that can engage with the pawl 25 is protruded so that when the movable piece 14 is folded back about the hinge portion 23, the pawl 25 and the pawl 26 can engage with each other. Further, a bolt insertion hole 27 is formed approximately in the center of the movable piece 14, and a pair of inclined locking claws 28 for temporary fixing protrude from the peripheral edge of the bolt insertion hole 27, facing each other. ing. The sharp tip of the locking pawl 28 protrudes to a length that engages with a thread groove when the bolt 20 is inserted into the bolt insertion hole 27.

Since this embodiment is configured as described above,
As shown in FIGS. 1 and 2, the movable piece 14 can be formed integrally with the holding member 12 in a shape extending laterally. In this case, the locking claw 2
Since the movable piece 14 having the number 8 is not located on the axial direction of the bolt insertion hole 18, there is no difficulty in removing the mold during molding.

When using the pipe holder 11, first, a pipe 29 such as a fuel tube or a brake tube is pushed through the pipe introduction part 16 and held by the seat 17. Next, as shown in FIG.
By engaging the movable piece 14 with the holding member 12, the movable piece 14 is fixed in contact with the holding member 12. At this time, the locking pawl 28 is located at the opening on the base end side of the bolt insertion hole 18. Since the tip of the movable piece 14 extending from one end of the holding member 12 engages with the other end of the holding member 12, external forces that tend to curve both sides of the holding member 12 upward during subsequent operations are avoided. Even if this external force is applied, the movable piece 14 resists such external force. Therefore, due to the curvature of the holding member 12, the pipe introduction part 16 opens, and the pipe 29 becomes partially dropped from the catch seat 17, causing rattling, which causes an abnormal noise problem when driving a car, for example. Malfunctions are effectively prevented.

Next, the pipe holder 11 is temporarily fixed to a bolt 20 protruding from a body panel 30 of a predetermined portion of the automobile. That is, as shown in FIG.
Insert into. When the movable piece 14 is seated on the body panel 30, the tip of the bolt 20 has reached a position facing the nut 13 temporarily attached to the holding member 12. In this state, the locking pawl 28 engages with the thread groove of the bolt 20, so that the pipe holder 11
is temporarily fixed. In such a temporarily fixed state, the piping condition of the pipe 29 is inspected, and the piping is corrected as necessary. Pipe holder 1 in temporary state
Since the bolts 1 can be removed more easily than the bolts 20, the piping modification work is easier.

Finally, the pipe holder 11 is permanently fixed. That is, the nut 1 is temporarily attached to the holding member 12.
3 (or by applying an external force in the screwing direction to the square head 22 with an appropriate tool) to cut the connecting portion 19 and tighten the nut 13 to the bolt 20.
5 until the position shown in FIG. By this operation, the nut 13 having the above-mentioned inner diameter is engaged with the male thread of the bolt 20 and fixed. Also, the holding member 12 is inserted through the flange 21 of this nut 13.
is fixed to the bolt 20, completing the installation of the pipe 29.

In this embodiment, the inner peripheral portion of the nut 13 may be formed smoothly or may be formed into a spline shape.

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

In this embodiment, at a predetermined portion of the movable piece 31,
Pipe introduction part 3 of catch seat 33 in holding member 32
Pipe holding protrusions 35 protruding in four directions are provided, and since the pipe 36 is supported by the protrusions 35, falling off of the pipe 36 from the seat 33 is more effectively prevented. Therefore, the above-mentioned countermeasure against abnormal noise becomes more complete. Note that FIG. 6 shows a state in which the movable piece 31 is folded back, and during molding, the movable piece 31 is molded in a shape extending to the side of the holding member 32, as in the case of the first embodiment. .

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

(Effect of the invention) According to the invention described in claim (1), the holding member for supporting the pipe in the pipe holder, the locking pawl for temporary fixing, and the nut for permanent fixing can be integrally molded.
Therefore, according to the pipe holder of the invention of claim 1, manufacturing costs including mold costs, processing costs, etc. can be reduced, and handling at the time of transportation, delivery, etc. can be facilitated,
Furthermore, ease of assembly during use can be improved.

In particular, in the invention of claim 1, the movable piece is provided with a locking claw for temporary fixing, so that the pipe holder that holds the pipe and has the movable piece folded back can be secured by the locking claw for temporarily fixing the movable piece. It can be temporarily fixed to the body bolt.

In addition to the effects of the above-mentioned invention of claim (1), the invention according to claim (2) can also effectively prevent the pipe from falling off due to the curvature of the holding member.
