Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a pipe holder for holding elongated objects such as automobile fuel pipes and brake pipes to a panel of an automobile body.

2. Description of the Related Art Several pipe holders made of synthetic resin have been developed for holding long objects such as fuel pipes and brake pipes on panels of automobile bodies. For example, in Japanese Utility Model Application No. 60-73987, a pipe holder is described.
Examples are given.

The pipe holder described in the above publication includes a stud fixing part that is fixed to a threaded stud fixed to a panel, a base body having a hole for receiving the stud fixing part, and a pipe holder that integrally extends laterally from the base body. The pipe holding part includes a pipe grip part that holds the pipe by pushing the pipe through the open part. In this pipe holder, the stud fixing part has a head that is formed to be rotatable relative to the pipe holder, and when the head is rotated, it is threaded by the mountain part of the stud and is threaded toward the panel side. It has a hollow shaft that moves forward. This pipe holder has the advantage that it is not necessary to use screws or nuts when installing the pipe, and the installation is extremely simple and easy.

Problems that the invention aims to solve Generally, car bodies are coated with vinyl chloride to prevent rust. Since this coating is applied to the entire surface of the vehicle body, in most cases it is also applied to the shafts of threaded studs that are fixed to the vehicle body. This application increases the diameter of the shank of the threaded stud by the thickness of the coating. This increase in the diameter of the shaft affected the temporary fixing function of the pipe holder. That is, due to the increase in the diameter of the shaft, a problem has arisen in that the stud holder of the pipe holder cannot be inserted unless the vinyl chloride coating is removed.

On the other hand, there are also pipe holders that utilize a vinyl chloride coating for temporary fixing.
In a pipe holder having such a structure, if the thickness of the coating on the outer surface of the shaft of the threaded stud is too thin, or if there is no coating on the outer surface of the shaft, there is a problem that the temporary fixing function is lost.

Therefore, the purpose of the present invention is to provide a threaded stud with a coating of vinyl chloride or the like that increases the diameter of the shaft, or even if there is no coating at all.
To provide a pipe holder that can be temporarily fastened to a screw stud and then easily permanently fastened.

Means for Solving the Problems In order to achieve this purpose, according to the present invention,

The stud fixing part has a head formed to be rotatable with respect to the pipe holding part, and when the head is rotated, the stud's crest part holds the stud. A pipe holder comprising a hollow shaft portion which is threaded and extends toward the panel side,
The stud fixing part and the pipe holding part are formed separately, and the base of the pipe holding part is formed into a hollow cylindrical body that receives the shaft part of the stud fixing part. A locking portion is formed on the outer surface of the shaft portion of the fixing portion to removably connect the pipe holding portion to the stud fixing portion, and the tip of the cylindrical base body is provided with a locking portion of the threaded stud. A locking pawl for temporary fixing is formed in the groove, and this temporary locking pawl is formed to engage in a V-shape with the outer periphery of the stud shaft, and is formed to engage the hollow shaft of the stud fixing part. A pipe holder is provided, characterized in that an inner surface is formed with a groove or a protrusion extending in the axial direction and forming an edge for cutting off a coating on the outer surface of the stud by rotation of the fixing part. be done.

Furthermore, a second embodiment of the pipe holder of the present invention is shown in FIGS. 8a to 12, and this second embodiment will be described later.

First, the structure of a pipe holder 1 according to a first embodiment of the present invention will be described in detail with reference to FIGS. 1 a to 2 f and 2 a to f. In the present invention, the pipe holder 1 has a stud fixing part 11 shown in FIGS. 2a to 2f, and a pipe holder 12 shown in FIGS. It consists of Among these, the stud fixing part 11 is
The threaded stud 6 fixed to the panel 5 is received and grasped, and the pipe holding part 12 is fixed to the panel 5.
The pipe holding part 12 is integrally formed with a cylindrical base body 14 in which a hole 13 (see FIG. 1 d and e) for receiving the shaft of the stud fixing part 11 is formed, and extends laterally on both sides from this base body. It is composed of a plurality of pipe grip parts 15, 16, 17, and 18.

Each of the pipe grip parts 15 to 18 is formed in a substantially U-shaped trough shape with an open upper part, and an elastic wing 19 is formed from the upper end of the trough to extend obliquely toward the bottom surface, and the pipe grip part 19 that is pushed in is I'm trying not to let it slip away. Note that it is preferable that reinforcing ribs 20 be formed on the bottom surface of the pipe holding portion 12.

The stud fixing part 11 includes a hollow shaft part 21 that receives the threaded stud 6, and a large diameter head that is integrally formed at the lower end of this shaft part 21 and presses and fixes the base body 14 of the pipe holding part 12 to the panel 5. 22. The head 22 is formed, for example, in a hexagonal shape so that it can be rotated by an impact driver or the like. Further, as shown in the figure, a flange 23 may be formed between the head 22 and the shaft portion 21 to press and hold the pipe holding portion 12.

As shown in FIGS. 2b and 2d, the tip of the shaft portion 21 is provided with a recessed locking portion 25 that locks into the protruding locking portion 24 inside the base 14 of the pipe holding portion 12.
As shown in FIG. 4c, the stud fixing part 11 is removably connected to the pipe holding part 12. When the head 22 is rotated with an impact driver or the like in this connected state, it advances along the thread of the stud, and the locking parts 24 and 25 are disengaged.When the head 22 is further rotated, the shaft part 21 is attached to the base of the pipe holding part 12. The head 22 advances through the hole 14 and comes into contact with the base 14. Therefore, the pipe holder 1 is fixed to the stud 6 by the rotation of the head 22,
In turn, the held pipes 2 and 3 are fixed to the panel 5. Note that the pipe holder 1 can be easily removed from the stud 6 by rotating the head 22 in the opposite direction.

In the present invention, the cylindrical base body 14 of the pipe holding part 12 has a locking pawl 26 formed at its distal end for temporarily fixing it in the groove of the screw stud 6. As shown in FIGS. 1a and 1e, this temporary fastening locking claw 26 is
A pair of holes are formed at the upper end, that is, the tip, of the cylindrical base 14 so as to face each other. Since this locking pawl 26 has a temporary fixing function, it is preferable that a slit 27 be formed on the side edge of the locking pawl 26 so as to have elasticity. As a result, the base 1 of the pipe holding part 12 to which the stud fixing part 11 is connected
4 into the screw stud 6, it can be easily temporarily fastened.

In the embodiment of the present invention, the temporary fixing pawls 26 are formed so that each pawl engages with the outer periphery of the shaft of the screw stud 6 in a V-shape, as shown in the figure. . By forming the stud in this manner, it bites into the outer peripheral surface of the stud, so that the temporary fixing function of the nail is maintained at a high level regardless of the thickness of the vinyl chloride coating. In particular, Figure 4c
As shown by the arrow, the tip end of the claw can be easily bent toward the opening side, and it can be pushed into the screw stud 6 easily.

Further, on the inner surface of the shaft portion 21 of the stud fixing portion 11, a locking pawl 28 is formed which enters into the groove of the screw stud 6 and locks the stud. In this example, three locking claws 28 are formed at equal intervals on the inner periphery of the hollow portion of the shaft. This locking claw 28 is different from the above-mentioned locking claw 26 and is used to permanently fasten the pipe holder 1 to the panel 5. Therefore, it is preferable to form it into a two-stage claw shape as shown in the figure, since this improves the fixing force.

By the way, in the present invention, the stud fixing part 11 is attached to the inner surface of the shaft part 21 of the stud fixing part 11.
A protrusion 29 is formed extending in the axial direction and forming an edge which cuts off the coating 7 on the outer surface of the threaded stud 6 by rotation of the stud. This protrusion 29 is
This removes vinyl chloride sol, etc., which are coated on the surface of the car body and the welded parts of the studs for purposes such as sound absorption, vibration isolation, and rust prevention. That is, as shown in FIG. 3, a coating 7 is attached to the surface of the panel 5, and a similar coating 7 is also attached to the outer surface of the threaded stud 6 during the coating operation. . This coaching 7
This may make it difficult to attach the pipe holder 1 or make it difficult to remove the holder for pipe replacement.

For this reason, on the shaft portion 21 of the stud fixing portion 11 of the pipe holder 1 of the present invention, a protrusion 29 that forms an edge for cutting off the coating 7 extends in the axial direction on the inner surface of the hollow portion of the shaft portion 21. It is formed.
In addition, in order to completely remove the coating 7, it is preferable that a plurality of these protrusions 29 are formed passing between the locking claws 29, and for the same reason, the inner surface of the shaft portion 21 is equally spaced. Preferably, they are formed extending at intervals. Furthermore, in consideration of the sharpness of the edge and the strength of the protrusion 29, the top of the protrusion 29 is formed thin on the tip side (the upper part in the figure), and thicker on the back side (the upper part in the figure). It is preferable to This situation is illustrated in FIGS. 2a, d, e and f. and as long as an edge is formed that removes the coating 7 on the outer surface of the threaded stud 6, the shank 21
It does not need to extend over the entire axial direction of the inner surface of the stud 6, but it is sufficient that the coating 7 is removed at least from the portion of the stud 6 that is locked by the locking pawl 28 for final locking.

Examples of fixing the pipes 2 and 3 to a panel 5 of a vehicle body or the like using the pipe holder 1 of the first embodiment are shown in FIGS. 4a to 7. below,
The operation of the pipe holder 1 according to the first embodiment will be explained.

In the pipe holder 1, as shown in FIG.
As shown in FIG.
4 is engaged with the recessed engagement section 25 of the shaft section 21 of the stud fixing section to form an integral assembly. This state becomes the packaging for delivery to the user (for example, a pipe processing manufacturer, etc.).

In order to fix each pipe 2, 3 to a panel 5 of a vehicle body or the like using the pipe holder 1 of the present invention which is an integral assembly, first, the pipe grip part 15 of the pipe holder 12 is fixed. - 18 are made to hold the required pipes 2 and 3 by pushing them in through the upper openings. This situation is illustrated in Figure 4a. From this state, the operator places the upper end, that is, the tip, of the base 14 of the pipe holder 12 against the tip of the screw stud 6 fixed to the panel 5 of the vehicle body, etc., and pushes it in with a finger or the like. As a result, the temporarily fastening locking claws 26 of the base body 14 are attached to the coating 7 made of vinyl chloride or the like, as shown in FIG.
It bites into and locks. That is, the holder 1 is temporarily fastened to the screw stud 6. Of course, if there is no coating 7, the temporary fastening locking claws 26 will lock into the valleys or grooves of the threaded stud 6 to temporarily fasten the holder 1 to the threaded stud 6, as shown in FIG. do. In this way, the holder 1 is temporarily fixed to the screw stud 6 regardless of the presence or absence of the coating 7, so that the positions of the pipes 2 and 3 on the panel 5 of a vehicle body or the like can be corrected to an appropriate arrangement.

After the pipes 2 and 3 are placed at appropriate positions, an impact driver, for example, is applied to the head 22 of the stud fixing part 11, and the stud fixing part 11 is pushed into the stud 6 and rotated. As a result, the inner surface of the shaft portion 21 of the stud fixing portion 11 is threaded by the threaded portion of the stud 6, and the entire stud fixing portion moves toward the panel 5 side. This movement causes the flange 23 of the stud fixing part to
presses the base 14 of the pipe holder 12 against the panel 5, thereby causing the entire pipe holder to press against the panel 5.
and in turn pipes 2 and 3 are fixed to panel 5.
Fixed. Therefore, the pipe holder 1 according to the present invention allows the pipe to be easily fixed to a panel of a vehicle body or the like using a tool such as an impact driver.

In addition, in the above example, the coating 7 of the threaded stud 6 is
Although the edges formed by the protrusions 29 are used to remove the coating, the edges from which the coating is removed can be formed by grooves instead of the protrusions. A modification of this stud fixing part 11 is the eighth one.
As shown in Figures a-f to 12.

This second embodiment will be described below. 8th
Referring to Figures a to f, in this embodiment, a groove 31 forming an edge for removing the coating 7 applied to the outer surface of the threaded stud 6 is provided on the inner surface of the shank 21 of the stud fixing part 11. It is formed to extend in the axial direction on the inner surface of the section. Note that this groove 31
As shown in the figure, it is preferable that the inlet portion of the shaft portion 21 be formed slightly larger to form a space in which the removed coating 7 can be stored. Further, it is preferable to increase the strength by narrowing the width of the groove at the inner part 32 (the lower part in the drawing) of the groove 31. FIGS. 9 to 9 show how the pipes 2 and 3 are fixed to the panel 5 using the pipe holder of the second embodiment in which the stud fixing part 11 and the pipe holder 12 shown in FIGS. 1a to 1f are assembled. Please refer to the diagram shown in FIG. Incidentally, the procedures for temporary fastening and final fastening are the same as those described in connection with FIGS. 4 to 7 above, and will therefore be omitted.
