Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a tube clamp structure, and in particular, to an improvement of a tube clamp structure suitable for use in converging and arranging tubes such as various tubes and cables in automobiles on the lower surface of a floor panel.

[Conventional technology]

Conventionally, in automobiles, a large number of tubes, cables, etc. are arranged under the floor panel of the car body. When arranging these tubes, if these tubes are placed carelessly, the maintenance inspection and installation process will become complicated.
I try to arrange multiple tubes together in an orderly manner. For this reason, as shown in FIG. 3, a piping clamp 3 is provided with a tube holding groove 2 for collectively holding a plurality of tubes, for example, a metal tube 1.
A tube clamp structure is adopted, which includes a clamp fitting 4 that holds the piping clamp 3 and is fixed to the body side. In such a tube clamp structure,
When fixing the piping clamp 3 to the clamp fitting 4, a mounting piece 5 is formed on the side opposite to the side where the tube holding groove 2 is formed of the piping clamp 3, and this mounting piece 5 is formed on the clamp fitting 4. Mounting hole 6
It is inserted and locked into place. Further, as disclosed in Japanese Utility Model Application Publication No. 59-121575, a mounting boss formed protruding on the side opposite to the side where the tube holding groove is formed of the piping clamp is inserted into the mounting hole of the clamp fitting, It has been proposed to fix the piping clamp to the clamp fitting by hot caulking the tip of the attachment boss.

[Problem that the invention attempts to solve]

However, in the conventional tube clamp structure described above, when attaching the piping clamp 3 to the clamp fitting 4, the piping clamp 3 is inserted into the mounting hole 6 while being twisted, and the piping clamp 3 and the clamp fitting 4 are inserted into the mounting hole 6. Since we are trying to fix the
When installing the piping clamp 3, it is necessary to fit the mounting piece 5 into the mounting hole 6 while twisting the piping clamp 3. For this fitting process while twisting, the clamp fitting 4 of the piping clamp 3 is required. There is a problem in that the assembly cannot be easily automated. Further, the tube clamp structure disclosed in the above-mentioned Japanese Utility Model Publication No. 59-121575 has the problem that the tip of the mounting boss must be heat-swaged, which increases the number of installation steps. Furthermore, in the above-mentioned conventional tube clamp structure, when the piping clamp is attached to the clamp fitting, the mounting piece 5 and the mounting boss for attaching the piping clamp protrude from the back surface of the clamp fitting 4 and are attached to the body. Since it is exposed to the outside, if this protruding part comes into contact with the ground or is hit by a flying stone while driving, the mounting piece or mounting boss will break off, causing the piping clamp to fall off from the clamp fitting. There is a problem with that.

[Purpose of invention]

This idea was made in view of the above-mentioned conventional problems, and it is easy to assemble the piping clamp and the clamp fitting, making it easily compatible with automation. To provide a tube clamp structure capable of preventing a piping clamp from falling off from a clamp fitting even when exposed to water.

[Means to solve the problem]

This invention provides a tube clamp structure having a pipe clamp equipped with a tube holding groove for holding a plurality of tubes in parallel, and a clamp fitting that holds the pipe clamp and is fixed to the body side. The clamp fitting includes a locking piece formed in a protruding manner on the piping clamp installation side and at a position facing the installation of the piping clamp, and the piping clamp faces the locking piece. a locking groove into which the locking piece is inserted in the piping direction of the tube, and the locking groove opens at one end side of the tube in the piping direction of the piping clamp and formed long in the direction,
A plurality of the locking pieces are arranged spaced apart in a parallel direction and in a direction perpendicular to the piping direction of the plurality of tubes, and are cut and raised from the clamp fitting, and have tips facing in the piping direction of the plurality of tubes. The above object is achieved by bending in a direction perpendicular to and in parallel to the above.

[Effect]

In this invention, the locking piece protruding from the clamp fitting is inserted and fitted into the locking groove formed in the pipe clamp in the piping direction of the tube, so that the pipe clamp can be easily clamped. can be attached to the clamp fitting. Moreover, this installation can be done easily by moving the piping clamp in the direction of the tube piping.
