Description

[Detailed description of the invention] [Industrial application field] The invention is generally applicable to automobiles, various machines,
This relates to the improvement of the structure of clamps for fixing pipes such as metal pipes with a relatively small diameter of approximately 30 m/m or less, or resin tubes, which are installed as supply paths for oil and air supply to equipment, etc. .

[Conventional technology]

Conventionally, as shown in FIG. 5, for example, as shown in FIG. 5, this type of fixed clamp has been designed so that the holding wall 12 is integrally assembled with the pipe P' by bending the approximately central portion in the longitudinal direction into a curved shape across the width direction. , and mounting holes 14 and 14' are formed in corresponding positions of flat walls 13 and 13' near both ends of the flat walls 13 and 13', which can be overlapped with each other, thereby constructing a clamp body 11 made of a metal strip plate. Was.

[Problem that the invention attempts to solve]

However, in such a conventional structure, when assembling the clamp body 11 to a predetermined position of the pipe P', the flat walls 13 near both ends of the clamp body 11,
13' portions are opened mutually, unless the flat walls 13, 13' are closed after assembly and the fastening members such as bolts are inserted into the mounting holes 14, 14'. 14' is not in phase, and when the opening is closed again, it is difficult to completely overlap the flat wall part due to spring back, and the gripping wall 12 becomes loose, which may cause the gripping wall 12 to become loose before it is installed in an automobile or equipment. Clamp body 11 when storing or carrying
This results in misalignment due to movement or loss due to detachment, which causes troublesome installation work during line assembly on-site, etc., and leads to stagnation of the work.

In order to deal with such problems,
A pipe clamp like the one disclosed in Publication No. 101080 has been proposed, but in order to pass the claw wall through the hanging hole and achieve the engaged state, it requires two operations: inserting the claw wall into the hanging hole and aligning the phasing of the mounting hole. Not only is this method necessary, but it also has problems such as the phase of the mounting hole being shifted due to spring back even when the pipe is gripped, making it impossible to put it to practical use.

The present invention very effectively solves the above-mentioned conventional problems, and in addition to the conventional structure, it facilitates the assembly of piping in a predetermined position, and also prevents positional displacement after a simple engagement operation on the clamp body. Another object of the present invention is to propose a fixing clamp that does not come off and can easily match the phase of the mounting holes.

[Means to solve the problem]

In the present invention, a gripping wall for assembling to a pipe is integrally provided by bending a substantially central portion in the longitudinal direction into a curved shape across the width direction, and flat wall portions near both ends of the wall that can be overlapped with each other are provided. In the clamp body, which is made of a metal band plate with mounting holes drilled therein, one wall has an insertion hole near the curved root forming the gripping wall, and the other wall has an insertion hole. Abstract: A clamp for fixing small-diameter piping is provided with a claw wall that passes through and projects in a substantially right angle direction, and a protrusion at the tip of the claw wall is configured to be freely engaged and detached from a hanging hole provided on the claw wall side of the gripping wall. That is.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. Fig. 1 is a plan view of the small diameter pipe fixing clamp of the present invention in a state assembled to a pipe, and Fig. 2 is Fig. 1A. - A cross-sectional view taken along line A, and FIG. 3 is a view equivalent to FIG. 2 showing another embodiment. The gripping wall 2 is integrally bent to form a curved shape and assembled onto the pipe P, and bolts or the like are tightened at corresponding positions of the flat walls 3 and 3' near both ends of the wall, which can be overlapped with each other. This is a clamp body with mounting holes 4, 4' for mounting. Reference numeral 5 denotes an insertion hole provided in one wall near the curved root forming the gripping wall 2, and an insertion hole cut into the other wall in the longitudinal direction of the metal strip so as to protrude in an approximately right angle direction. 3.Fold the tip of this bent piece to the flat wall 3.
A claw wall 6 that is bent substantially parallel to the projection 6' to form a protrusion 6'.
Also, a hanging hole 5' is provided on the claw wall 6 side of the gripping wall 5.
is provided, and when the pipe P is assembled at a predetermined position, the protrusion 6' at the tip of the claw wall 6 passing through the insertion hole 5 is configured to engage with the hanging hole 5'.

[Effect]

Since the present invention is constructed in this way, the flat walls 3 and 3' near both ends of the clamp body 1, which can overlap, are opened (Fig. 3) and assembled at a predetermined position of the pipe P. During the subsequent closing operation, the claw wall 6 passes through the insertion hole 5 (Fig. 4), and as the closing operation progresses gradually, the protrusion 6' at the tip of the claw wall 6 springs back to the outer periphery of the gripping wall 2. The surface is rubbed, and finally the protrusion 6' engages with the hanging hole 5' to fix the pipe P with the clamp body 1, and the mounting hole 4,
4' phase is maintained in a warm state.

[Effect of idea]

As explained above, the small-diameter pipe fixing clamp according to the present invention has a pair of hooking structures near the curved base forming the gripping wall 2 and is configured to be freely engaged and detached. The piping P is fixed by the engagement of the protrusion 6' with the support hole 5, and the phase of the mounting holes 4 and 4' is aligned, making it extremely easy to insert bolts, etc., thus making it easier to assemble the clamp body 1. Even when storing or transporting the clamp body afterwards, there is no need to worry about the clamp body shifting its position due to movement or losing it due to detachment, and it eliminates the hassle of installation work when assembling the line on site, making it extremely useful. A clamp for fixing small diameter piping.
