Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pipe clamp for holding a pipe of an automobile or the like.
[0002]
[Prior art]
Conventionally, for example, in order to hold a pipe for an air conditioner of an automobile, a pipe clamp as shown in FIG. 7 is used. The clamp 101 is made of a material such as resin, and is formed with a pipe fitting portion 103 for fitting and holding the pipe. Then, after a cushion material 107 made of a material such as urethane is wound around the pipe 105, the pipe 105 is held by being fitted into the pipe fitting portion 103 of the clamp 101. That is, the vibration is transmitted to the pipe 105 from the compressor of the air conditioner, but the vibration is absorbed by the cushion material 107 and the pipe 105 is prevented from dropping from the pipe fitting portion 103 of the clamp 101. It has been done.
[0003]
[Problems to be solved by the invention]
However, in the configuration in which the cushion material 107 is wound around the pipe 105 as described above, there is a problem that the cushion material 107 is easily displaced. When the cushion material 107 is displaced, a situation occurs in which the pipe 105 is dropped from the fitting portion 103 of the clamp 101. On the other hand, in order to prevent the pipe 105 from dropping even if the cushion material 107 is displaced to some extent, the cushion material 107 has to be made longer than necessary, and there is a problem that the material is wasted.
[0004]
The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a pipe clamp that fits and holds a pipe more firmly without displacement of the cushion material.
[0005]
[Means for Solving the Problems]
In order to achieve this object, the pipe clamp according to claim 1 forms a pipe fitting portion for fitting and holding the pipe in a clamp body made of a resin material, and the pipe fitting portion has a rubber. In particular, at least one through hole is formed in the pipe fitting portion of the clamp body, and the cushion material is integrally formed through the through hole. Therefore, since the cushion material is formed connected integrally through the through-hole, is rigidly fixed to the clamp body without using an adhesive, never positional deviation occurs.
[0006]
In the pipe clamp according to claim 2, the surface of the portion of the cushion material where the pipe abuts is formed in an uneven shape. Accordingly, the uneven surface formed on the cushion material prevents slipping of the fitted pipe, so that the pipe is held extremely firmly.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a pipe clamp embodying the present invention will be described with reference to the drawings. Here, FIG. 1 is an overall perspective view of a pipe clamp showing an embodiment of the present invention, and FIG. 2 is an overall perspective view showing a state in which the pipe is held by the pipe clamp. FIG. 3 is a perspective view of the clamp body, and shows a state before a cushion material to be described later is attached by insert molding. 4 is a right side view of the pipe clamp shown in FIG. 1, FIG. 5 is a front view seen from the direction of arrow A in FIG. 4, and FIG. 6 is a sectional view taken along line BB in FIG. is there.
[0009]
The piping clamp 1 of this embodiment is comprised from the clamp main body 2 and the cushion material 7 which consists of rubber materials, such as an elastomer, as shown in FIG. The clamp body 2 is a member manufactured by molding a synthetic resin material such as polyacetal, for example, and has a substantially triangular overall shape that expands downward in a side view and has a rounded upper portion. . The clamp body 2 is formed with two pipe fitting portions 3 and 9 having a substantially C-shape in a side view opening toward the front side by side, and formed integrally with the pipe fitting portions 3 and 9. The back portion 4 is formed linearly and obliquely. Further, the lower end portion 6 extending in the horizontal direction is formed with a fixing portion 11 protruding downward for attachment to a vehicle panel (not shown). Further, flange portions 10 projecting laterally from both surfaces of the plate-like portion 8 of the clamp body 2 are formed along the outline.
[0010]
The pipe fitting parts 3 and 9 are parts for fitting and holding the pipe 5 together. In particular, a vibration-preventing cushioning material 7 is insert-molded and attached to the pipe fitting portion 3 in order to attach a pipe with high vibration. An example of a pipe having a lot of vibrations is a pipe for an air conditioner of an automobile and connected to a compressor. On the other hand, since a pipe with relatively little vibration is attached to the pipe fitting portion 9, unlike the pipe fitting portion 3, the cushion material 7 is not provided. As shown in FIGS. 3 and 4, four through holes 3 a, 3 b, 3 c, 3 d are formed in the vicinity of the pipe fitting portion 3 of the clamp body 2. Further, as shown in FIGS. 1, 3, and 6, reinforcing ribs 13 are formed on the outside of the pipe fitting portion 3 in order to improve the strength of the pipe fitting portion 3 of the clamp body 2. The through hole 3c is formed in the reinforcing rib 13, and the through hole 3d is formed in the plate-like portion 8.
[0011]
As shown in FIGS. 1 and 4, the cushion material 7 is attached by insert molding rubber such as elastomer so as to cover the pipe fitting portion 3 of the clamp body 2, and penetrates the clamp body 2 described above. They are integrally connected through the holes 3a to 3d. Accordingly, the cushion material 7 is extremely firmly fixed to the clamp body 2 without being bonded with an adhesive or the like. As shown in FIGS. 1, 4, and 5, a plurality of protrusions are provided at predetermined intervals on the inner side of the cushion material 7, that is, on the surface of the portion where the pipe 5 is fitted and abutted. When the is fitted, an uneven bead 7 a formed in parallel with the length direction of the pipe 5 is formed. The uneven bead 7a is formed to hold the pipe 5 more firmly by preventing slippage with the pipe 5 fitted. In the pipe clamp 1 configured in this way, as shown in FIG. 2, the pipe 5 is held by fitting the pipe 5 into the pipe fitting portion 3.
[0012]
As is apparent from the above description, according to the pipe clamp 1 of the above embodiment, the cushion material 7 is attached to the clamp body 2 side, so that the cushion is as in the conventional configuration in which the cushion material is wrapped around the pipe. The problem of material misalignment does not occur. Moreover, since it is not necessary to make the cushion material longer than necessary unlike the prior art, there is an advantage that the material is not wasted. Moreover, since the cushion material 7 is insert-molded integrally through the through holes 3a to 3d formed in the clamp body 2, there is an advantage that it is not necessary to apply and bond an adhesive.
[0013]
Moreover, since the cushion material 7 is provided so that the circumference | surroundings of the pipe fitting part 3 may be covered, there also exists an effect of preventing generation | occurrence | production of abnormal noise. Furthermore, since the concave and convex beads 7 are formed on the cushion material 7, it is possible to prevent the pipe 5 from being slipped and to hold the pipe 5 more firmly.
[0014]
In addition, this invention is not limited to embodiment mentioned above, A various change is possible in the range which does not deviate from the main point of this invention. For example, in the above embodiment, the clamp body 2 is formed of polyacetal, but may be formed of other resin materials. Moreover, although the cushion material 7 was formed with the elastomer, you may form with another rubber material.
[0015]
Moreover, in the said embodiment, although the four through-holes 3a-3d were formed around the piping fitting part 3 of the clamp main body 2, a through-hole does not necessarily need to be formed. Further, the number of through holes is not limited to four, and may be four or more, and may be less than four. Further, it may be a through hole penetrating the pipe fitting portion 3 in the radial direction.
[0016]
Moreover, in the said embodiment, although the cushion material 7 was integrally attached to the clamp main body 2 by insert molding, you may attach the cushion material 7 to the clamp main body 2 after shape | molding separately.
[0017]
Moreover, although the uneven | corrugated bead 7a was formed in the surface of the part to which the piping 5 of the cushion material 7 is fitted and contact | abutted, it is not restricted to the aspect which forms a some protruding item | line like FIG. For example, the surface may be formed in a jagged shape, or a plurality of warped projections may be formed on the surface.
In short, the surface portion of the cushion material only needs to be processed so as to prevent the pipe from slipping and to hold the pipe more firmly.
[0018]
Moreover, in the said embodiment, although the fitting part 3 was formed more firmly with the reinforcement rib 13, if the intensity | strength can fully be ensured, it is not necessary to provide the reinforcement rib 13. FIG.
[0019]
【The invention's effect】
As is apparent from the above description, according to the pipe clamp according to claim 1, at least one through hole is formed in the pipe fitting portion of the clamp body, and the cushion material is interposed through the through hole. They are connected together. Therefore, since the cushion material is formed connected integrally through the through-hole, is rigidly fixed to the clamp body without using an adhesive, there is an effect that never positional deviation occurs.
[0020]
Moreover, according to the clamp of piping of Claim 2, the surface of the part which piping of the said cushion material contact | abuts is formed in unevenness. Therefore, in addition to the above-described effects, the uneven surface formed on the cushion material prevents the fitted pipe from slipping, so that the pipe is held extremely firmly.
