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. 57-113777, 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 grooved stud fixed to a panel of a vehicle body, a base body in which a hole for receiving the stud fixing part is formed, and an integral part laterally from this base body. The stud fixing part and the pipe holding part are integrally molded through a thin wall part. In this pipe holder, when the stud fixing part is hammered in, the thin wall part breaks and the pipe holder is pressed together with the pipe against a panel such as a vehicle body, thereby fixing the pipe to the panel. This pipe holder has the advantage that the pipe can be attached by hammering it in, making it easy to operate, and eliminating the need to use screws or nuts.

Problems to be Solved by the Invention However, with the above-mentioned pipe holder, it is not possible to temporarily fasten the pipe when installing it, which makes it somewhat troublesome to install the pipe. Also,
In the case of the above-mentioned holder, if the hammering is weak, the installation will be insufficient, and on the other hand, if the hammering is too strong, there is a risk that cracks will occur in the stud fixing part.

5 is shown installed.

Referring to FIGS. 1a-g to 3a and b, the pipe holder 1 includes a stud fixing part 11 for receiving and grasping a threaded stud 2 as a grooved stud fixed to a panel 3, and a stud fixing part 11 for receiving and grasping a threaded stud 2 fixed to a panel 3. The pipe holding section 12 is fixedly attached to the section 11 and holds the pipes 4 and 5. The pipe holding part 12 has a hole 10 for receiving the stud fixing part 11.
(see FIG. 1e), a cylindrical base 13,
It is comprised of a plurality of pipe grip parts 14 integrally molded so as to extend laterally from this base body.
The pipe grip part 14 is open at one end, and by pushing the pipes 4 and 5 through the opening 14',
Hold the pipe from the side. Preferably, the pipe grip portion 14 is provided with a spring piece 15 that presses against the side surface of each pipe to prevent it from coming off. In addition, the pipe holding part 14
Preferably, reinforcing ribs 16 are formed on the bottom surface of the holder.

The stud fixing part 11 includes a hollow shaft part 18 that receives the stud 2, and a base body 13 of the pipe holding part 12.
and a head 19 that is pressed against the panel 3 and fixed, and when the head 19 is hammered with a hammer or the like,
A hollow base body 13 of the pipe holding portion 12
into the hole 10, the pipe holder 1 is fixed to the stud 2, and the held pipes 4, 5 are fixed to the panel 3. The head 19 is preferably formed into a hexagonal shape as shown in the figure so that it can be rotated by a tool or the like. This configuration has the advantage that the pipe holder 1 can be easily removed from the stud 2 by rotating the head 19.

In the present invention, an elastic locking pawl 21 that locks into the trough of the threaded stud 2 as a grooved stud is provided on the inner surface of the shaft portion 18 of the stud fixing portion 11 on the distal end side of the stud fixing portion 11 (as shown in the figure). Further, between the locking pawl 21 and the head 19, a reduced diameter portion 22 is formed to have a diameter smaller than the outer diameter of the stud. In order to form the locking pawl 21 and the reduced diameter portion 22, a hole 23 is formed in the surface of the head 19 of the stud fixing portion 11 in correspondence with the locking pawl 21. Furthermore, a slit 24 is formed on the side surface of the shaft portion 18 to form the reduced diameter portion 22. As shown in the figure, a plurality of slits 24 (three in the illustrated example) are formed in the inner circumferential direction of the shaft part 18 and are open to the outside of the shaft part. As shown in FIG. 1g, a plurality of slits 24 (3
Since the structure is provided between the reduced diameter portions 22 provided in
2. It makes it easier to bend outward, making it easier to insert the shaft into the stud. In addition, the length of each reduced diameter portion 22 in the axial direction (vertical length in FIG.
(see also figure b), thereby reducing the diameter of the reduced diameter section 22
Not only is the stud firmly fixed to the stud, but the reaction force when the stud fixing part 11 is inserted into the stud is reduced.

Note that the stud fixing part 11 is connected to the pipe holding part 12 via the thin wall part 26, as shown in FIG. 1e.
The thin wall portion 26 is broken by striking the head portion 19 of the stud fixing portion. In this way, by molding the pipe holder 1 as a whole as an integrally molded product, there is an advantage that the pipe holder according to the present invention can be handled as a single product.

In this way, when the thin wall portion 26 is broken to separate the stud fixing part 11 and the pipe holding part 12, the stud fixing part 11 rotates with respect to the threaded stud 2 due to vibrations of the automobile, etc., and the panel 3 There is a risk that the fixation may become loose. Therefore, on the outer surface of the shaft portion 18 of the stud fixing portion 11 according to the present invention, a protrusion 28 is formed at a position close to the head 19 so as to bite into the side surface of the hole 10 of the base body 13 of the pipe holding portion 12. It is formed. Therefore, the stud fixing portion 11 may be damaged even by vibrations from an automobile or the like.
This prevents the pipe from rotating relative to the pipe holding portion 12, thereby eliminating the risk of loosening the fixation of the pipe. As for the position of the protrusions, a pair of protrusions may be formed facing each other in the diametrical direction, as shown in FIG. In this case, there is an advantage that a force acts to tilt the reduced diameter portion 22 inward, increasing the fixing force of the reduced diameter portion.

An example of fixing several pipes 4 and 5 to a pipe 3 of a car body or the like shown in FIG. 2 using the pipe holder 1 according to the present invention is shown in FIGS. 3a and 3b. . That is, the pipe grip portions 14 of the pipe holding portion 12 are made to hold the required pipes 4 and 5, respectively. In this state, the worker first temporarily fixes the holder 1 by pushing the head 19 of the stud fixing part of the pipe holder 1 into the threaded stud 2 fixed to the panel 3 of the vehicle body etc. with a finger or the like. do. That is, the locking pawl 21 formed on the inner surface of the shaft portion 18 of the stud fixing portion 11 of the holder locks into the groove of the stud 2, and the pipe holder 1 is temporarily fixed to the stud 2. This temporary fixing allows the positions of the pipes 4 and 5 on the panel of the vehicle body to be corrected to an appropriate arrangement, so it is extremely preferable in practice. Note that in this case, the thin portion 26 is formed to have enough strength to not break.

After that, after arranging the pipes 4 and 5 at appropriate positions, the head 19 of the stud fixing part 11 is fixed, for example.
The groove portion 26 of the pipe holder 1 is broken by striking with a hammer or the like, and the shaft portion 18 of the stud fixing portion 11 is inserted into the hole 10 of the base 13 of the pipe holder 12. By this hammering, the protrusion 28 is formed in the hole 10 of the base 13 of the pipe holding part 12.
It bites into the inner surface of the stud and prevents the stud fixing part 11 from rotating relative to the pipe holding part 12.

What is more important is that by this hammering, the reduced diameter part 22 of the stud fixing part 11 is locked by the mountain part of the stud 2, and not only the locking force of the locking pawl 21 but also this contraction is applied. With the addition of the locking force of the diameter portion 22, the fixing force of the stud fixing portion 11 increases, and the positions of the pipes 4, 5 on the panel 3 are reliably fixed.

Effects of the invention According to the invention, on the inner surface of the shaft part of the stud fixing part, there is a locking pawl that has elasticity that locks into the groove part of the stud, and a locking claw with a diameter smaller than the outside diameter of the stud at a position close to the head. A plurality of molded reduced diameter parts are formed in the inner circumferential direction of the shaft part with slits opening to the outside of the shaft part in between, and each reduced diameter part is formed in one groove of the stud. Since the pipe holder is formed with an axial length that is long enough to fit into the stud, it is possible to temporarily fasten the pipe holder to the stud, and even when it is permanently fastened by hammering, the bending of the reduced diameter part will reduce the force. can be made sufficiently small, thereby preventing damage to the stud fixing part, and since the reduced diameter part firmly engages with the stud, an extremely reliable and stable fixing force can be obtained.
