[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a metal pipe having a relatively small diameter of about 20 m / m or less, which is provided in an automobile or various machines and devices as a supply passage for oil supply and air supply. The present invention relates to an improvement in a structure for fixing pipes such as a flexible tube or wire harness made of rubber or resin, or a clamp body for cables such as optical fibers (hereinafter simply referred to as pipes).

[0002]

2. Description of the Related Art Conventionally, as a fixing structure for pipes of this type, for example, as shown in the cross section of FIG. 4, on the surface of a substrate (11) made of a strip-shaped steel material having a mounting hole (12) on one end side, A plurality of direct pipes (P ') are arranged in parallel, and their abutting portions are fixed (13), for example, by welding or brazing in the case of a metal pipe.

[0003]

However, in such a conventional technique, the rust-preventive coating of the substrate (11) applied in advance or the pipe (P ') made of a metal pipe is applied to this pipe. Since the rustproof coating that was used is also damaged by heating during welding or brazing, rustproofing is not required again after fixing.
When making products that are long and have a complicated bending shape, the processing is extremely troublesome, and when welding or brazing, it is fixed in the case of thin-walled tubes due to overheating.
In the (13) part, mechanical strength is deteriorated on the side of the metal pipe, which often causes cracks and breakage, and when replacing any of the pipes (P ') due to a defect in the arranged pipe (P'), individual pipes
There is a problem in that the entire product must be replaced by making it impossible to remove (P ').

Further, although the conventional clamp body can individually fix the brazable or weldable metal pipes, there is a problem that the flexible tubes and the pipes such as cables cannot be collectively fixed. I had one.

The present invention has been made in view of the above-mentioned problems of the prior art. Not only is the clamp body used with a rust preventive coating, but even if the pipes are metal pipes, a rust preventive coating is applied beforehand. Can be used, there is no need to perform rust prevention again after fixing, there is no fear of deterioration of mechanical strength at the fixing part on the piping side, and individual piping can be replaced due to malfunction. An object of the present invention is to provide a structure for fixing pipes by a clamp body, which can be made possible and can collectively fix various pipes having different materials and diameters.

[0006]

In order to achieve the above object, the present invention provides a flat portion on the other end side of a base plate made of a strip-shaped steel material having a bent wall at least one end side of which a mounting hole for a base body is formed. A plurality of J-shaped, L-shaped, or U-shaped wrapping pieces having at least one shape are formed on the surface of the forming surface, and the holding pieces are positioned parallel to each other with their respective groove sides facing in the same direction. A plurality of pipes are arranged in the concave groove portion of each holding piece of the clamp body formed by fixing the space around the bottom wall and by fixing the vicinity of the bottom wall portion and the space between the bent wall and a plurality of pipes. The gist is a fixing structure of pipes by a clamp body configured by curving the end toward the curved wall side in a curl shape and collectively embracing and fixing.

[0007]

Since the present invention has such a structure, by using the clamp body to which a plurality of the holding pieces are fixed, the pipes are collectively put in the space between the concave groove portion of the holding piece and the bent wall. Therefore, if the clamp body and the pipes that have been previously coated with a rust preventive film are metal pipes, it is possible to use a metal pipe that has a rust preventive film in advance and re-fix after fixing the pipes. No need for rust prevention, and it is possible to replace individual pipes when there is a problem with the arranged pipes. Also, because fixing means by heating at the fixing part is not required, Cracks due to deterioration of mechanical strength of
It is possible to eliminate the fear of breakage, etc., it is possible to collectively fix flexible tubes made of rubber, resin, etc. and piping such as cables such as wire harnesses and optical fibers, and the material,
It can be applied without being affected by the diameter and shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a structure for fixing pipes by a clamp body of the present invention, and FIG. 2 is a sectional view taken along the line A--A of FIG. FIG. 3 is a view corresponding to FIG. 2 according to another embodiment, in which (1) is a clamp body, and one end side (FIG. 2) or both end sides (FIG. 3) of the mounting hole with bolts to the base body ( 2) Or J-shaped or L-shaped on the surface of the flat part on the other end side of the substrate (1 ') made of a strip-shaped steel material having a bent wall (1 ") with (2) and (2') drilled Or / and U
With a plurality of wrapping pieces (3) each having a V-shape, the concave groove sides are positioned in the same direction and parallel to each other, and with a space (4) between them, close to the bottom wall. Is fixed (5) by welding or brazing.
It is pre-coated with rust by plating or painting. Then, each free end of each of the wrapping pieces (3) is provided with a plurality of pipes (P) in the space (4) between the groove and the bent wall (1 "). It is constructed by curving in a curl shape toward the side and enclosing and fixing the pipes together. (6) in FIG.
A curved receiving member that is provided in the space between (1 ") and stabilizes the pipes (P) at the time of wrapping and fixing, and the solid arrow indicates the curl shape at the free end. It shows the respective bending directions of.

[0009]

As described above, the structure for fixing pipes by the clamp body according to the present invention has a plurality of the holding pieces.
By using the clamp body (1) in which (3) is fixed (5) to the surface of the substrate (1 '), each free end of the groove of the holding piece is curled toward the curved wall (1 ") side. Since it is bent in a circular shape to enclose and fix various pipes (P) such as metal pipes, flexible tubes and cables all together, a clamp body (1) with a rust preventive coating in advance and, if desired, in advance It is possible to use a metal pipe with an anticorrosion coating, and it is possible to eliminate the need for a second anticorrosion treatment after fixing the pipe. It is not possible to replace it, and the fixing structure that does not require heating at the fixed part of the pipes (P) can eliminate the fear of cracks and breakage due to deterioration of the mechanical strength of the pipes, etc. It is a structure for fixing pipes by a useful clamp body.
