Description

[Detailed Description of the Invention] Different Fields of Application The present invention relates to a pipe holder used to secure pipes such as fuel pipes and brake pipes of automobiles to panels of vehicle bodies and the like.

Prior Art In order to hold and fix fuel panels and brake pipes of automobiles to vehicle body panels, the pipes are held using metal holders, and the holders are screwed to the vehicle body panels. However, this metal holder is not preferred because it damages the pipe and generates abnormal noise due to vibrations from the automobile. For this reason, there are methods in which the holder is coated with resin, the pipe is coated with resin, and even a rubber cushion is provided between the holder and the pipe, but all of these methods are undesirable because they lead to increased costs. In addition, since the retainer is fixed to the panel with screws and nuts, it is not possible to prevent the occurrence of abnormal noise, and rust occurs due to electric contact, and washers must be attached to prevent the fixation from coming off. There is a disadvantage. In particular, mounting with screws and nuts requires drilling into the panel, and the subsequent welding of the nuts to the panel makes work difficult in the narrow spaces of automobiles.

For these reasons, it is preferable that the entire pipe holder be made of a resin material. Unexamined Japanese Patent Publication 1978
JP-A-687 discloses a pipe holder made of a resin material. This known pipe holder consists of a strut for engaging a threaded stud welded to the panel and a pipe holder formed integrally with the strut on the side of the strut. A shaft hole for inserting a screw stud is formed in the support column. The inner diameter of the shaft hole is slightly smaller than the outer diameter of the stud, and when the pipe holder is attached to the stud, the thread of the stud bites into the inner surface of the column. The pipe holder is therefore firmly fixed to the stud.

With this known resin pipe holder, in order to obtain strong fixation when attached to the stud,
It is necessary to make the diameter of the shaft hole of the strut portion sufficiently smaller than the diameter of the threaded portion of the stud. However, when the diameter of the shaft hole of the support column is reduced in this way, the pushing force required to insert the pipe holder into the stud increases, making installation difficult.

Problems to be Solved by the Invention The present invention is a pipe holder that is made entirely of resin material to prevent noise and rust, and that is easy to attach to a threaded stud and that is compatible with the stud. The problem to be solved is to provide a pipe holder that can be firmly fixed.

Means for Solving the Problem In order to solve this problem, the pipe holder of the present invention has a shaft hole for inserting the threaded stud, that is, a stud insertion hole formed in the main body that engages with the threaded stud. It has a diameter larger than the outside diameter of the stud. An elastic locking pawl for engaging with the thread of the stud is formed in the insertion hole so as to project inwardly at an angle in the stud insertion direction. Furthermore, grooves are formed along the wall surface of the insertion hole so as to extend above and below the locking claw, and both sides of the locking claw are separated from the main body through a slit, and the base portion is connected to the main body. connected.

That is, as shown in FIG. 2, a pipe holder 1 is used to hold a plurality of pipes 3, 3 on a panel 2 of an automobile, etc., and uses threaded studs 4 fixed to the panel 2 by welding or the like. It is designed to be fixed to the panel 2. The pipe holder according to the present invention, not only in the first embodiment but also in the second embodiment described later, is made of synthetic resin and is integrally molded, thereby preventing rust and noise from occurring due to vibration. There is.

In FIGS. 1a to 1i, a pipe holder 1 according to a first embodiment of the present invention has a main body 10 which can be attached by simply pushing into a threaded stud 4 fixed to a panel 2, and a pipe holder 10 which can be attached by simply pushing the pipe into a threaded stud 4 fixed to a panel 2. It consists of a pipe gripping part 11 that grips the side surface.

In the first embodiment, one pipe gripping part 11 is provided on each side of the main body part 10, and each pipe holding part 11 is adapted to hold the pipe 3. As shown in FIG. 1a, each pipe gripping part 11 has a wide opening at the top, the entrance thereof is slightly narrower than the diameter of the pipe 3, and the inner part thereof is widened again to form a bay shape. It has two spring pieces 13, 14, and these spring pieces 13, 14 are made of plate-shaped bodies as shown in FIGS. 1b to d.

The lower spring piece 13 integrally extends laterally from the bottom surface of the main body 10 and then curves upward to form a groove 15 for holding the pipe 3 between the lower spring piece 13 and the outer surface of the main body 10 . extends outward and upward and forms a guide surface when the pipe 3 is pushed in. Note that the size of the groove 15 is the same as that of the pipe 3.
It is enough to touch and hold the side of the
Preferably, the size is such that it can be slid with a certain amount of force, so that the holder 1 can be moved along the pipe 3 while attached to the pipe 3 and aligned with the stud.

The upper spring piece 14 is a spring piece that presses the side surface of the pipe so as to hold the pipe 3 housed in the groove 15 formed by the lower spring piece 13, and may have any shape as long as it has this function. In this first embodiment, the groove 15 extends sideways from above the main body 10, and then extends downward to narrow the entrance of the groove 15, and is attached to the side surface of the main body 10 so that its tip presses against the pipe side surface. It extends towards.

The main body part 10 supports the grip part 11 and is formed in a cylindrical shape so as to surround the stud 4 as shown in FIG. 2, and as shown in FIG. A stud insertion hole 16 whose diameter is enlarged enough to escape the fillet of the stud and whose upper part is formed as a blind hole, and a lock which projects inward to engage with the thread of the inserted stud 4. It is provided with a pawl 17 and a through groove 18 extending in the length direction along the insertion hole 16 above and below the locking pawl 17.

The groove 18 is formed to pass through the upper part of the main body 10 and is necessary for forming the locking pawl 17. It facilitates the formation of the locking pawl 17 and prevents the locking pawl 17 from being bent. make it easier Furthermore, when slits 19 are formed on both side edges of the locking pawl 17 to increase the elasticity of the locking pawl 17, the grooves 18 facilitate the formation of the slits 19. By forming this slit, the elasticity of the locking pawl 17 is maintained while the stud insertion hole 1 is inserted.
The diameter of the stud 6 can be made slightly larger than the outer diameter of the stud, which prevents the holder 1 from wobbling relative to the stud 4.

Preferably, three locking claws 17 are provided along the circumference of the stud insertion hole 16 so as to engage with three locations on the circumferential surface of the thread of the stud 4. Strengthens the adhesion to 4. Each of the locking claws 17 is inclined upward as shown in FIG. As mentioned above, slits 19 are formed on both side edges of the locking pawl 17, thereby providing the necessary flexure during insertion.

As shown in FIGS. 1a and 1i, a pair of spring pieces 21 extending outward and downward are provided on the bottom surface of the main body 10 or the bottom surface of the lower spring pieces 13 of the pipe holding part 11, so that the holder 1 It is also preferable to increase the locking force by applying a repulsive force to the panel 2 when it is attached to the stud 4. However, such a spring piece is not essential and may be omitted.

Further, it is preferable that a recess 22 is formed on the front surface of the main body 10, thereby reducing the weight of the holder as a whole and reinforcing the main body as shown in FIG. 1f.

3a to 3i show a pipe holder according to a second embodiment of the present invention, and FIG. 4 shows how the pipe 3 is fixed to the panel 2 using this holder. In this embodiment, the main body 10 held by the stud is the same as in the first embodiment, and its explanation will be omitted.

In the second embodiment, the pipe gripping section 11 includes two
Two pipes 3, 3 are provided side by side on one side of the holder main body 10 so as to grip two pipes 3, 3. That is, the upper spring piece 14' extends so as to act as a holding member for the grip part 11 on one side, and the lower spring piece 13' extends largely from the main body part 10 so as to form two grip parts 11. ing. This lower spring piece 13' has one pipe 3
A partition 25 is formed in the middle to protrude upward so as to hold another pipe 3 therein, and further extend laterally from this partition 25 and extend upwardly so as to hold another pipe 3 inside. It is curved inward and gripped to form a holding member for the pipe 3.
Note that it is preferable to form a slit 28 in the middle of the partition 25, so that it is possible to accommodate slight changes in the outer diameter of the pipe. Also, this slit 28
This also helps to reduce the weight of the entire holder, and for the same purpose, it is preferable to form the lower surface of the upper spring piece 13' thin and to provide a rib 29 in the center for reinforcement. Also,
In this example, one of the lower spring pieces 21 extends from the bottom surface of the main body 10, while the other spring piece 21 extends from the bottom surface of the main body 10.
extends from the lower surface of the lower spring piece 13' forming the grip.

Similarly to the pipe holder 1 of the first embodiment, the pipe holder 1' of the second example also has a main body 10 attached to the stud 4.
The pipes 3, 3 can be easily attached by pushing them into the grips 11, 11. Main body part 1
0 is provided with three locking claws 17, so that the holder 1' is firmly fixed to the panel. In this case, since the diameter of the stud insertion hole 16 is formed to be approximately equal to the outer diameter of the stud, the locking pawls are locked evenly, and the locking does not come off due to vibration.

Effects of the invention According to the pipe holder according to the invention, the holder main body has a stud insertion hole that has a diameter larger than the outer diameter of the stud and extends upward from the bottom surface, and a stud insertion hole that is provided in the insertion hole and that is connected to the thread of the stud. An elastic locking pawl with a tip that is inclined in the stud insertion direction and protrudes inward to engage with the stud, and an elastic locking pawl formed above the locking pawl to extend in the length direction of the main body along the wall surface of the insertion hole. Since both sides of the locking pawl are separated from the main body through a slit and connected to the main body at the base, it is possible to push the insertion hole into the stud with a small force. In this case, the locking pawl can be easily bent and does not create a large resistance to pushing in. Therefore, the rigidity of the locking pawl itself can be increased while maintaining the necessary elasticity. ,
Therefore, the locking force of the locking pawl after insertion can be maintained at a high level, and the holder can be prevented from falling off from the stud.
