Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a mounting structure for a wiring pipe clamp, and more specifically, it is used to centrally connect various types of piping and/or wiring to a fixed object such as the floor of an automobile or machinery equipped with a hydraulic system. , relates to a structure for attaching a raceway clamp, which supports a plurality of these pipes and/or wires together on a fixed body, to the fixed body.

[Conventional technology]

An example of a clamp for centralized piping is a "resin fixing clamp for centralized piping" described in Japanese Utility Model Application Publication No. 54-68071. This device is configured so that a clamp having a tube holding portion formed to hold a plurality of tubes and/or wires in parallel can be fixed to an object with a single touch. , an elastically deformable umbrella-shaped locking stopper is provided protruding from the appropriate part of the clamp, and when this locking stopper is pushed into the support hole drilled in the object to be fixed, the umbrella of the stopper automatically closes. The portion is adapted to be engaged with and fixed to the peripheral edge of the support hole.

[Problem that the idea aims to solve]

However, in such a clamp, the clamp is simply held by the elastic engagement between the locking stopper and the object to be fixed, so the installation strength is low, and it cannot be used under the floor of a car, construction machinery, etc. This method is unsuitable for cases in which the clamp must be securely fixed to a fixed object with large vibrations over a long period of time. Furthermore, in the past, screws were generally used to fix the clamp to objects subject to large vibrations such as those mentioned above, but in this case, the tube was held in the tube holder in advance. The screws had to be screwed in using a tool while holding the clamp in place, resulting in poor workability. That is, it is difficult to hold the clamp in a predetermined position and to screw in the screw with two hands, so two people have no choice but to perform the above operations. This device is designed to attach the clamp to the fixed member of the fixed object using screws (bolts), and this mounting section can be attached to the fixed member of the fixed object with one touch. The objective is to dramatically improve workability when attaching a clamp to a member to be fixed by providing a temporary fixing function that allows the clamp to be fixed.

[Means to solve the problem]

In order to solve the above problems, this invention takes the following technical measures. That is, the present invention has a tube holding portion formed to be able to hold a plurality of tubes and/or wires in parallel, and a raceway clamp made of an elastically deformable material is attached to a fixing member. It has a structure that is attached by bolt fastening, and the fixing member is formed into a plate shape with a constant width and a screw hole in the middle in the width direction, while the wiring pipe clamp has an elongated bolt insertion hole. have,
A mounting portion is integrally formed with a pair of hook-shaped engagement protrusions having oblique guide surfaces facing each other at an interval corresponding to the width of the fixing member with the bolt insertion hole in between, and the pair of hook-shaped engagement protrusions After the raceway clamp is temporarily held against the fixing member by engaging with both side edges of the fixing member, the bolt passed through the bolt insertion hole is screwed into the screw hole. It is characterized by

[Effect]

When the plate-shaped fixing member is pushed relatively between the pair of hook-shaped engagement protrusions, the engagement protrusions face each other in correspondence with the width of the fixing member, so the oblique guide surface of the engagement protrusion After the clamps are forcibly spread apart from each other, the hooks elastically return to grip the both edges of the fixing member, and the attachment part of the clamp is automatically temporarily held against the plate-like attachment member. That will happen. Next, by screwing the bolt inserted into the bolt insertion hole from the back side of the attachment part of the clamp temporarily held in this way into the screw hole of the fixing member,
The clamp is firmly fixed to the fixed member.

[Explanation of Examples]

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. The clamp 1 is made of an elastically deformable material such as resin, and has an elongated rod-like shape as a whole, and a mounting portion 3 having a bolt insertion hole 2 is integrally formed at one end 1a. On the upper surface of the clamp 1, there are tube holding parts 5, 5, .
...is provided. The tube holding parts 5, 5... may be configured as appropriate so that when the tubes 4, 4... are pushed in, they can automatically hold the tubes elastically, but in the illustrated example, a cylindrical groove is formed on the inner periphery. A plurality of pairs of holding pieces 5a and 5b are formed on the upper surface of the clamp 1 and project upwardly so as to face each other. When the tubes 4, 4, etc. are pushed downward between the tips of the pair of holding pieces 5a and 5b, that is, into the groove,
After the holding pieces 5a, 5b are forcibly expanded, they elastically return to hold the tubes 4, 4, etc. so as to tightly embrace them on the cylindrical inner peripheral surface. Note that the inner diameter and number of the grooves of these tube holding parts may be appropriately selected depending on the outer diameter and number of tubes to be held. The bolt insertion hole 2 provided in the mounting portion 3 has a second
As best seen in the figure, it is a long hole.
The relative position of the bolt 8 with respect to the screw hole 7 previously provided in the fixing member 10 to which the clamp 1 is to be fixed can be adjusted. The fixing member 10 is formed into a plate shape having a constant width, as shown by the imaginary line in FIG. As a result, the screw hole 7 is formed. A pair of hook-shaped engagement protrusions 9, 9 which should provide a temporary fixing function are further integrally formed on the mounting portion 3. The engaging protrusions 9, 9 have vertical portions 9a, 9a located opposite to each other so as to sandwich the bolt insertion hole 2, and protrude upward from the upper surface 3a of the mounting portion 3;
It consists of inclined parts 9b, 9b which incline downward from the tips of the vertical parts 9a, 9a inwardly. The distance between the upper portions of the inward surfaces of the inclined portions 9b, 9b is made to correspond to the width of the plate-shaped fixing member 10. Therefore, the inclined portions 9b, 9b function as oblique guide surfaces that are gradually elastically pushed apart as the both side edges 10a, 10b of the plate-shaped fixing member 10 slide, and the inclined portions 9b, The lower open end of 9b is
As hook portions 12, 12 which elastically return after being pushed and spread as described above and engage with both edges 10a', 10b' of the upper surface of the fixing member 10 to prevent the fixing member 10 from coming off. Function. From the above, for example, the pair of hook-shaped engagement protrusions 9, 9 are attached to the fixing member 10 extending from the floor surface of an automobile, etc., and the fixing member 10 is placed between the oblique guide surfaces 11, 11. Apply it so that it fits, and then press the clamp 1 toward the fixing member.
The clamp 1 is automatically temporarily held against the fixing member as shown in FIG. To finally fix the clamp 1, as shown in FIG. 3, a bolt 8 inserted into the bolt insertion hole 2 from the back side is screwed into a weld nut 7a fixed in advance to the back side of the fixing member 10. . At this time, since the clamp 1 is temporarily held on the fixing member 10, both hands can be used to screw in the bolt, making it extremely easy to do so. The pair of hook-shaped engaging protrusions 9, 9 need only have oblique guide surfaces 11, 11 and hook portions 12, 12, and even if they are formed as shown in FIG. It has exactly the same effect.

[Effect of the idea]

As described above, according to the mounting structure of the raceway clamp according to the present invention, the fixing member to which the clamp is fixed with bolts is formed into a plate shape having a constant width and having a screw hole in the middle in the width direction. On the other hand, the wiring pipe clamp has a pair of hook-like hooks each having an elongated bolt insertion hole and having oblique guide surfaces facing each other at a distance corresponding to the width of the fixing member across the bolt insertion hole. Since the mounting part with mating protrusions is integrally formed, simply by placing the fixing member between the engagement protrusions and pressing the clamp toward the fixing member, the engagement protrusions will automatically attach to the fixing member. It engages with both side edges, thereby making it possible to easily temporarily hold the clamp on the fixing member. Therefore, the work of finally fixing the clamp to the fixing member with the bolt becomes easier, resulting in the effect of significantly improving the installation workability. At this time, since the bolt insertion hole is an elongated hole, even if the above temporary holding position is rough, the final fixing position of the clamp can be easily adjusted within the range allowed by the elongated hole. There are some effects that can be achieved.
