Description

[Detailed Description of the Invention] U Industrial Field of Application] The present invention generally relates to a pipe having a diameter of 20 m, which is installed as a supply path for fuel, other refueling, air supply, etc. in automobiles or various mechanical devices. The present invention relates to a fixing clamp for small-diameter pipes that can be held at appropriate positions in the length direction of a plurality of metal pipes or resin tubes (hereinafter simply referred to as pipes) having a relatively small diameter of about 1.2 m or less, and a method for fixing the same.

[Prior Art] Conventionally, this heel fixing clamp and its fixing method are as follows: As illustrated in FIG. Holding the clamp body (11) provided with The parts are pressed and curved to engage in an enclosing manner and fixed, or the joint surfaces formed with the wall or the gripping wall (12) are fixed by welding them together with solder. there were.

[Problems to be Solved by the Invention] However, in such conventional technology, it is difficult to contain or mutually support the straight pipes of the pipes (pV, storage, etc.) installed in parallel. Due to the fixation by solder welding, the vibration of the vehicle body or mechanical equipment may occur over a long period of time while the piping is in place.In the former case, pressure at the tip of the gripping wall (12) or spring back that occurs when curved. Due to the wrapping-like slack, the piping (P;', storage...) may be misaligned in the length direction and rotated in the circumferential direction, or scratches may be caused on their mutual circumferential surfaces. In the latter case, the entire product is coated with a corrosion-resistant coating such as a plating film after hot solder welding, so the plating process with a complex bent shape causes considerable work hassle. This leads to problems such as impeding workability and making it difficult to form a plating film that exhibits the desired high corrosion resistance.

SUMMARY OF THE INVENTION An object of the present invention is to provide a clamp for fixing a small-diameter pipe and a method for fixing the same, which effectively solves the problems described above with the prior art.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a plate-shaped clamp body that has a wall near one end for attachment to a base body, and has inclined walls on both sides in the width direction. A pair of notches are made in the other longitudinal end of the clamp body to incorporate a notch hole and piping, and the tip thereof is bent and fixed to the other end of the clamp body. The gist of the present invention is a fixing clamp for small-diameter piping, which is configured by forming a tongue-shaped clamping wall with a protruding claw, and maintaining a gap for piping assembly between the clamping wall and the notch hole; The other end side and the protruding part are fixed by hooking the protruding claw or the folded part of the protruding claw to the bending wall of the other end on the back side of the notch hole, or after superimposing the protruding claw on the surface of the other end. The overlapping part is caulked or glued with a U-shaped fastener,
Or, the overlapping part is folded back, and the mounting part to the base body has a wall near one end, and sloped wall parts on both sides in the width direction, and the longitudinal part is attached to the other end in the longitudinal direction. A pair of notches are made in the direction to form a notch hole and a tongue-shaped clamping wall with a protruding claw at the tip, and a gap is maintained between the clamping wall and the notch hole during assembly. With a plate-shaped clamp body constructed of The gist of the present invention is a method for fixing a fixing clamp for a small-diameter pipe in which the bent portion of the pipe is brought into contact with the inclined wall portion.

[Function] Since the present invention is configured as described above, after the clamp body is assembled into the clamping wall portion on the straight peripheral surface of the pipe, the tip portion is bent and fixed to the other end side of the clamp body. The structure of the protruding claw and the contact structure between the bent part of the pipe and the inclined walls on both sides of the clamp body in the width direction prevent misalignment in the length direction and rotation in the circumferential direction of the pipe, respectively. It is possible to easily and reliably fix these parts without causing any scratches on their mutual circumferential surfaces, and the use of pre-plated piping and clamp bodies significantly improves workability. .

[Example 1] Hereinafter, embodiments of the present invention will be described based on the drawings. Fig. 1 is a plan view showing a pipe fixing state of a fixing clamp according to a fixing clamp for a small diameter pipe of the present invention and a method for fixing the same; Figure 2 is a plan view of the single fixing clamp shown in Figure 1 before piping is fixed, Figure 3 is an enlarged cross-sectional view taken along line A-A in Figure 1, and Figure 4 is the

The clamping wall (4) maintains a gap (6) between the notch hole (3) and the piping (P1, P2...) for assembling, and furthermore, a gap (6) is maintained between the clamping wall (4) and the notch hole (3). When assembling, the pipes (P, P2...) are assembled in parallel to the gap (6), and then bent, the other end (1b) is bent on the back side of the notch hole (3). An integrally formed refraction wall (l
b') is provided with a protruding pawl (5) which is hooked and fixed in a resilient manner. By this fixing, the piping (P, P...) is elastically clamped in the gap (6) during the assembly, and the bent portion (p;, p, ;・・
) is brought into contact with the inclined wall portion (1', 1°) and held securely. Note that the protruding claw (5) and the other end (1b) can be fixed not only in the above embodiment but also by providing a folded part (5°) in the protruding claw (5) as shown in FIG. (
lb"), or overlap the protruding claw (5) on the surface of the other end (1b) as shown in Figs. 6 and 7, and then
It can also be caulked or glued using a letter-shaped stopper (Fig. 6), or by folding back the overlapping part (Fig. 7).

Also, in the above embodiment, multiple pipes were explained, but
The present invention is also applicable to piping having one bent portion.
