Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pipe holder, and more specifically, it is used to clamp pipe bodies such as fuel pipes and brake tubes, for example, in the engine room of an automobile or on the underside of a floor panel. This product relates to pipe holders used for pipe holders.

(Prior Art) As an example of such a conventional pipe holder,
There is a pipe holder 1 made of synthetic resin shown in FIG.

In this device, an insertion port 3 is opened in a circular hole-shaped seat 2 set to a predetermined inner diameter, and a pipe 4 is inserted while elastically pushing and expanding the insertion port 3 as shown by the imaginary line in Fig. 13. I'm starting to do that.

(Problem to be solved by the invention) However, in the above pipe holder 1, the pipe 4
If it is thinner than the inner diameter of the catch 2, it may wobble or the insertion slot 3
In order to freely pass through and exit the catch plate 2,
If the inner diameter is larger than the inner diameter, the insertion port 3 remains expanded and the pipe 4 is likely to fall off, so the pipe 4 cannot be held effectively in either case. In other words, the catch 2 is inconvenient in use because it can only be adapted to pipes of one size.

Furthermore, due to such drawbacks, when a plurality of pipes 4a, 4b, and 4c of different diameters arranged in a specific order as shown in FIG. 14 are clamped together,
There was also the inconvenience of having to prepare a special product in which seats 2a, 2b, and 2c with corresponding inner diameters were arranged in the same order.

Therefore, the technical problem to be solved by the present invention is to enable one or more holding parts provided in a pipe holder to be adapted to pipes of several different thicknesses. Another object of the present invention is to provide a pipe holder that can firmly hold pipes with different outer diameters without wobbling.

(Means for Solving the Problems) A technical means for solving the above problems is a holder for a pipe clamp comprising one or more holders each having a pipe insertion port and a seat. ,
The insertion port is divided into several lengths and protrudes along the axial direction of the pipe toward the receiving seat,
Furthermore, when inserting the pipe, a plurality of tongues for preventing the pipe from coming off are provided, which can be deflected to escape positions that do not interfere with the insertion of the pipe; , is characterized in that it is provided with a holding piece for a pipe receiver whose opening angle can be elastically expanded.

(Operation) The pipe is inserted while displacing the tongue piece to the escape position. Since the plurality of tongues are divided, they act independently. When the pipe reaches the catch seat, the opening angle of the holding piece changes elastically depending on the various thicknesses of the pipe, and one of the plurality of tongue pieces of a predetermined length returns to its original pipe holding position. Returns elastically to position. Since the holding piece is flexible and has an arcuate cross section, it has good ability to hold pipes of various diameters. The pipe is effectively held by the holding piece and the tongue piece of a predetermined length.

(Example) Next, the configuration of a first example of the present invention will be described based on FIG. 1.

A wall 7 extends from the center of the base 6 of the synthetic resin pipe holder 5, and a pair of side walls 8 extend from the left and right ends.
However, each wall is built upright. A pair of pipe holding portions 9 are formed between the wall portion 7 and the pair of side wall portions 8 as follows.

That is, a circular hole-shaped seat 10 is formed extending from the left and right side surfaces of the wall portion 7, through the upper surface of the base 6, to the inner surface of the side wall portion 8, and the upper opening of the seat 10,
That is, the space between the tops of the wall portion 7 and the side wall portion 8 serves as the insertion opening 11 .

Slanted guide surfaces 12 facing the insertion port 11 are formed on the left and right sides of the top of the wall portion 7, and from the top of the side wall portion 8 there is formed a guide surface 12 having a thickness that can be elastically bent toward the center of the seat 10. Two flat plate-shaped tongue pieces 13 and 14 are diagonally protruded along the axial direction of the pipe to which the pipe is attached. Tongue piece 13,1
4 are formed independently from each other along the same plane, and protrude to different predetermined lengths. Therefore, the upper surfaces of the tongue pieces 13 and 14 are aligned with the guide surface 1.
The tongue piece 1 serves as a guide surface facing the tongue piece 2.
A claw piece 15 for preventing the pipe from coming off along the circumferential direction of the catch seat 10 is integrally formed at the tips of the pipes 3 and 14.

On the other hand, on the lower side of the seat 10, a holding piece 16 for holding a pipe is provided, which is shaped like a vertically divided cylindrical body and opens in an arc shape toward the insertion port 11. This holding piece 16 is formed integrally with the upper end of the leg 17 that protrudes along the center of the bottom of the catch seat 10, and is curved concentrically with a predetermined distance between it and the catch seat 10. , the circumferential line along the inner curved surface is set to pass through the tip of the longer protruding tongue piece 14. Note that holding piece 1
6 is formed such that the portion on the side of the wall portion 7 is relatively long and the portion on the side of the side wall portion 8 is relatively short, and the tongue pieces 13, 14
open facing directly. Further, the holding piece 16 is formed to have a thickness that allows it to be elastically bent.

This embodiment is constructed as described above and is used as follows.

First, the case of holding a small-diameter pipe 18 whose outer diameter coincides with the circumferential line along the inner curved surface of the holding piece 16 will be described based on FIGS. 2a to 2c. Figure 2a
Connect the pipe 18 to the guide surface 12 and the tongue piece 13,
Insertion port 1 is guided by the upper guide surface of 14.
1 into the catch seat 10, the tongues 13 and 14 are deflected to the escape position to allow the pipe 18 to enter, as shown in FIG. 2b. When the pipe 18 is placed on the holding piece 16 as shown in FIG. 2c, the tongue piece 1
3 and 14 elastically return to their original positions by passage of the pipe 18. At this time, the tip of the shorter tongue piece 13 does not reach the pipe 18, but the longer tongue piece 14
The claw piece 15 at the tip comes into contact with the pipe 18 to prevent the pipe 18 from coming off from the seat 10. The pipe 18 is thus effectively clamped by the holding piece 16 and the tongue piece 14.

Next, the case of holding a large-diameter pipe 19 whose outer diameter is larger than the small-diameter pipe 18 by the difference in the protruding length between the tongue pieces 13 and the tongue pieces 14 will be explained based on FIGS. 3a to 3c. explain. As the pipe 19 is pushed in as shown in FIGS. 3a and 3b, the holding piece 16 elastically expands its opening angle to accept the pipe 19, as shown in FIG. 3c. At this time, both ends of the holding piece 16 are set so as to be in contact with and supported by the wall surface of the seat 10. On the other hand, the longer tongue piece 1
4 is kept displaced to the escape position by the pipe 19, but the shorter tongue piece 13 elastically returns to its original position, and its claw piece 15 comes into contact with the pipe 19 to prevent it from coming off. Do this. The pipe 19 is therefore effectively clamped by the holding piece 16 and the tongue piece 13.

As described above, the pipe holder 5 of this embodiment can be adapted to pipes of two different diameters, the small-diameter pipe 18 and the large-diameter pipe 19, in each of the pair of pipe holders 9.

In this embodiment, the pipe holder 5 may include only one pipe holder 9 or three or more pipe holders 9. Further, the inner curved surface of the holding piece 16 may be formed along a circumference smaller than that of the small diameter pipe 18. Furthermore, by protruding three or more tongue pieces of different lengths, the structure may be adapted to accommodate pipes of three or more different thicknesses.

Next, an example of a modification of the structure of the holding piece in this embodiment will be explained based on FIGS. 4 to 6.

The holding piece 16a shown in FIG. 4 protrudes from the wall portion 7. As shown in FIG. The holding piece 16b shown in FIG.
more prominent. Holding piece 16c shown in FIG.
is the catch seat 1 along the extension line in the protruding direction of the tongue pieces 13 and 14.
It is supported by legs 17 provided at 0.

Next, a second embodiment of the present invention will be described based on FIG. 7.

In the pipe holder 20 of this embodiment, long and short tongue pieces 23 and 2 similar to the first embodiment are provided at the insertion opening 21 of the pipe holder, protruding from the side wall 22.
4, a long and short tongue piece 2 protruding from the wall portion 7
5 and 26 are provided laterally symmetrically with the tongue pieces 23 and 24, respectively. Moreover, the holding piece 27 is open toward the middle of the tongue pieces 23, 24, 25, and 26 on both sides. In this embodiment, the pipe is held down from both sides by a pair of long or short tongues, so the pipe is held more firmly. The configuration, operation, and effects of other points in this embodiment are the same as those in the first embodiment.

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

In the pipe holder 28 of this embodiment, a pair of long and short tongue pieces 31 and 32 protrude from the center wall 30 in the pair of pipe holders 29, respectively.
A pair of long and short tongue pieces 34 and 35 protruding from the left and right side wall parts 33 are arranged alternately as shown in the figure. In this embodiment, when the pipe is held down from both sides by a pair of long or short tongues, the holding parts from both sides are shifted along the axial direction of the pipe, so that it has a retaining effect over a longer width. Therefore, the holding force of the pipe becomes stronger than that in the second embodiment. The other aspects of the structure, operation, and effects of this embodiment are the same as those of the first embodiment or the second embodiment.

The pipe holders 5, 20, and 28 according to the first to third embodiments are provided with appropriate means (not shown) for attaching them to a panel body or wall in the engine room or the lower surface of the floor. ing.

Next, a fourth embodiment of the present invention will be described based on FIGS. 9 to 12.

The pipe holder 36 of this embodiment is also made of synthetic resin, and a nut 38 and a boss 39 for mounting to the panel are integrally provided vertically through the center of the base 37, and on the left and right sides of the nut 38 and boss 39 are integrally provided. Two pipe holding parts 40 are provided consecutively on each base 37. In addition, the pipe holding part 4 on the right end side in FIG.
0, only one wide tongue piece 41 is protruding. In addition, in the other three pipe holding sections 40, the holding pieces 42 are formed to have a narrow width in the pipe axial direction, thereby making it easier to cause bending deformation in the direction of increasing the opening angle. A reinforcing rib 43 is formed on the lower surface side of the base 37.

The boss 39 is a cylindrical body with a window 44 projecting upward from the base 37, and a flange-like cover plate 45 is provided at the upper end of the boss 39. As shown in FIG. 10, the lower opening of the boss 39 has a boss 39
The nut 38, the upper end of which is fitted into the inside of the nut 38, is connected via a thin link 46.

The nut 38 is formed into a cylindrical shape that is long in the axial direction, and a pair of temporary fixing claws 47 protrude toward the center from the tip of the inner circumference. Also, Natsu 38
An appropriate number of protrusions 48 are formed along the axial direction on the inner circumferential surface. These protrusions 48 are formed at a height that overlaps with a male thread of a stud bolt 49, which will be described later. A flange 50 is provided on the lower end side of the nut 38 and can be engaged with the lower opening of the boss 39.

The pipe holder 36 of this embodiment is used as follows. That is, while clamping a predetermined pipe (not shown) by each pipe holding part 40,
As shown in FIG. 10, the pipe holder 36 is temporarily attached by engaging the claw 47 of the nut 38 with the male thread of a stud bolt 49 fixed to a panel 51 of the engine room or the like. Then, check the piping, and if there is a problem, check the stud bolt 49.
After removing the nut 38 and redoing the piping, if there is no problem, push the nut 38 upwardly into the boss 39 by press-fitting (taking into account rotation if necessary). At this time, the thin joint 46 is torn and the nut 38 is pushed into the state shown in FIG. The male thread of the stud bolt 49 bites into the synthetic resin protrusion 48 of the nut 38 to firmly connect the two, and the boss 39 is held by the flange 50 of the nut 38, thereby holding the pipe. The tool 36 is permanently fixed to the panel 51.

(Effects of the Invention) The present invention is easy to use because the single or multiple holding parts provided on the pipe holder can be adapted to several different diameter pipes, and is also suitable for clamping multiple pipes of different diameters together. It can respond to changes in the arrangement order of each pipe.

That is, the pipe holder of the present invention has a plurality of pipe retaining devices that are divided into several lengths and protruded along the axial direction of the pipe and toward the pipe seat at the pipe insertion port. Because the tongue piece was provided,
Each tongue piece can act independently, and when the pipe reaches the catch, one of the multiple tongue pieces of a predetermined length returns to its original position and prevents it from coming off. The diameter pipe can be held well without rattling.
