Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing device for resin pipes used for supplying working fluid, and more particularly to a technique for improving workability of fixing resin pipes and reducing costs.

[0002]

2. Description of the Related Art A resin pipe used for supplying a working fluid has a merit that it can be bent to some extent and has a high degree of freedom, so that wiring is easy. It has the drawback of swinging a lot when stopped. When the resin pipe swings largely, it may hit the structure around it and interfere with it, and the resin pipe may be damaged. Therefore, as shown in FIG. 5, in order to prevent the interference between the resin pipe 1 and the structure 2, the resin pipe 1 is fixed to the wiring portion by using a plurality of clips 3.

[0003]

However, in order to fix the resin pipe with the clip, the work of fitting and fixing the clip in the fixing hole formed in the wiring portion was indispensable. For this reason, when the resin pipe is installed in a portion where the operator's hand is hard to enter, it is difficult to fix the clip, and the labor is extremely large. In addition, depending on the wiring portion of the resin pipe, the clip may not be used due to the relationship with the surrounding structure.

Incidentally, in order to improve the fixing property of the resin pipe, Japanese Utility Model Publication No. 6-84092 and Japanese Utility Model Publication No. 6-840.
Although the technique disclosed in Japanese Patent Publication No. 91 has been proposed, none of them considers workability and cannot reduce the labor of the worker. Therefore, in view of the conventional problems as described above, the present invention significantly reduces the required clips by restricting the runout movement of the resin pipe, and makes it possible to improve the fixing workability of the resin pipe and reduce the cost. An object is to provide a fixing device for resin pipes.

[0005]

Therefore, according to the first aspect of the invention, a core member having a polygonal cross section and extending along the wiring direction of the resin pipe and an outer shape of the core member are formed. A thin plate-shaped main body made of an elastically deformable member, which has a fixing portion for holding and fixing the resin pipe.
It is characterized in that the fixing device for the resin pipe is configured to include.

According to this structure, the resin pipe is fixed to the wiring portion by the following procedure. That is, the fitting hole of the main body is fitted into the core material to form a fixing device in which the main body is fixed to the core material. At this time, since the cross section of the core material is polygonal, rotation of the main body with respect to the core material is prevented. Next, the pipe fixing device is arranged along the wiring direction of the resin pipe, and the resin pipe is held and fixed by the fixing portion.

[0007] Then, even if the resin pipe tries to vibrate largely when starting or stopping the supply of the working fluid, the vibrating motion is restricted by the pipe fixing device, and even if there is a structure near it, Interference with this is prevented. Further, since it is not necessary to fix a large number of clips to the wiring portion of the resin pipe, the labor required for the fixing work is reduced, and the work time is shortened to reduce the cost. Further, the main body is lightweight because it has a thin plate shape, and is easy to handle.

In the invention according to claim 2, the fixing portion of the main body has a groove shape following the outer shape of the resin pipe, and the opening is formed smaller than the outer diameter of the resin pipe. And According to this structure, when the resin pipe is clamped and fixed to the main body, the resin pipe is brought into contact with the opening of the fixing portion and is pressed inward of the fixing portion. Then, since the main body is made of the elastically deformable member, the surfaces facing each other in the opening are elastically deformed and expanded outward, and the resin pipe is fitted into the fixed portion. When the resin pipe is fitted into the fixing portion, the surfaces facing each other in the opening are elastically restored to return to the original position, and the resin pipe is firmly held and fixed by the fixing portion.

The invention according to claim 3 is characterized in that the main body has a substantially circular outer shape, and a plurality of fixing portions are formed on the outer periphery thereof. According to this structure, it is possible to fix a plurality of resin pipes with one fixing device. In the invention according to claim 4, the core material has a regular polygonal cross section.

According to this structure, it is possible to change the direction in which the main body is fitted to the core material, and by arbitrarily combining the main bodies having various shapes, an unnecessary fixing portion is not formed and an arbitrary number The resin pipe of is fixed. Further, by changing the fitting direction of the main body with respect to the core material according to the wiring direction of the resin pipe, the resin pipe can be arbitrarily twisted.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows a first embodiment of a resin pipe fixing device (hereinafter referred to as “pipe fixing device”) according to the present invention. The pipe fixing device 10 is configured to include a core member 12 extending along the wiring direction of the resin pipe 20 and a main body 14 fitted and fixed to the core member 12.

The core material 12 is made of a material that is difficult to deform, for example, a steel material or a stainless material, and is formed in a shape having a regular polygonal (square in this embodiment) cross section. On the other hand, the main body 14 is made of an elastically deformable member, for example, a resin such as nylon or a rubber material (preferably a hard rubber material), and is formed in a thin plate shape having a substantially circular outer shape. And the main body 14
