A structure is characterized in that a reference flat plate portion 1b connected to the clamp portion 1a and a movable flat plate portion 1c are formed so as to be substantially parallel to each other while the pipe 3 is clamped to the clamp portion 1a of the clip body 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to the structure of a pipe fastening clip for fixing a single pipe or a plurality of pipes together to a fixing portion.

[0002]

[Prior art]

 Generally, a pipe fastening clip having a clamp portion bent in an arc shape for clamping a pipe is known. As shown in FIG. 5, this type has a clip body 31 manufactured by bending a single steel plate, and the clip body 31 has an arc-shaped clamp portion 31a for clamping a pipe. A reference flat plate portion 31b connected to the clamp portion 31a and a movable flat plate portion 31c are provided (for example, Japanese Utility Model Laid-Open No. 60-29982).

[0003]

[Problems to be solved by the device]

 However, in the above-described conventional configuration, after the pipe is clamped in the clamp portion 31a, the bolt 33 is passed through the hole of the movable flat plate portion 31b, and the tip of the bolt 33 is pressed against the hole of the reference flat plate portion 31c. When attempting to screw it into the female screw portion of the fixing portion 35, there is a problem that the bolt 33 tilts and its tip hits a portion other than the hole of the reference flat plate portion 31c and cannot be screwed in smoothly.

This is because the movable flat plate portion 31b is originally tilted with respect to the reference flat plate portion 31c by a predetermined angle θ, and since there is the tilt θ, conventionally, The movable flat plate portion 31b and the reference flat plate portion 31c must be pushed parallel to each other by the amount of the angle θ and then fixed by the bolts 33, which causes a problem of extremely poor workability.

Further, since the dimension 1 between the movable flat plate portion 31b and the reference flat plate portion 31c becomes longer due to the angle θ, the bolt 33 must be strongly pressed when it is stopped by the bolt 33. However, there is a problem that workability is poor.

Therefore, an object of the present invention is to solve the problems of the above-described conventional technique and to improve the workability in bolting, as compared with the conventional one. To provide clips.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is configured such that the reference flat plate part and the movable flat plate part connected to the clamp part are approximately parallel to each other in a state where the pipe is clamped to the clamp part of the clip body. It is characterized by.

[0008]

[Action]

 According to the present invention, when the pipe is clamped in the clamp portion of the clip body, the reference flat plate portion connected to the clamp portion and the movable flat plate portion also connected to the clamp portion are substantially parallel to each other, so that the movable flat plate portion When the bolt penetrates the hole, the tip of the bolt is directed to the hole of the reference flat plate portion, and the bolt can be screwed in as it is, so the bolting work is extremely easy.

【Example】

 Hereinafter, an embodiment of a pipe fastening clip according to the present invention will be described with reference to FIGS. 1 to 4.

In FIG. 1, reference numeral 1 denotes a clip body. This clip body 1 is manufactured by bending a piece of steel plate into a large area in the area A and then a small area in the area B. Further, according to this embodiment, as will be described later, it is characterized by the bending method in the B region.

The clip body 1 is formed of a clamp portion 1a bent in an arc shape for clamping the pipe 3, a reference flat plate portion 1b connected to the clamp portion 1a, and a movable flat plate portion 1c also connected to the clamp portion 1a. Has been done.

The reference flat plate portion 1b and the movable flat plate portion 1c are provided with holes 7 and 9 for passing the bolts 5, respectively.

At the stage of manufacturing the clip body 1, the area A is largely bent to first form the clamp portion 1a, and then the area B is folded so that the movable flat plate portion 1c and the reference flat plate portion 1b are parallel to each other. To be formed. In short, the bending in the region B is performed at an angle such that the movable flat plate portion 1c and the reference flat plate portion 1b after the bending are parallel to each other.

According to this embodiment, however, since the reference flat plate portion 1b and the movable flat plate portion 1c are parallel to each other after the pipe 3 is clamped in the clamp portion 1a, the holes of the movable flat plate portion 1c are parallel to each other. When the bolt 5 is passed through the bolt 9, the tip of the bolt 5 almost certainly points to the hole 7 of the reference flat plate portion 1b. Therefore, as shown in FIG. 2, it is possible to screw the bolt 5 into the fixing portion 11 as it is. it can.

That is, according to this, the workability in fastening the bolt 5 can be significantly improved as compared with the conventional one.

FIG. 3 shows another embodiment.

The clip body 1 is different from the above-described embodiment only in that the shape of the clamp portion 1a is such that a plurality of (three) pipes 3 can be clamped. The same is true in that the reference flat plate portion 1b and the movable flat plate portion 1c are formed in parallel with each other.

That is, as is clear from this embodiment, the clamp portion 1a can be formed in any shape.

FIG. 4 shows still another embodiment.

According to this, one of the holes 7 and 9 formed in the reference flat plate portion 1b and the movable flat plate portion 1c (in this example, the hole 7) can be a long hole. If one of them is a long hole, some inclination of the bolt 5 is absorbed, so that the workability when fixing the bolt 5 can be further improved.

In each of the above embodiments, the case where the bolt 5 is used has been described as an example, but it goes without saying that a tapping screw or the like may be used instead of the bolt 5. It is possible.

[0022]

[Effect of device]

 As is clear from the above description, according to the present invention, when the pipe is clamped in the clamp part of the clip body, the reference flat plate part connected to the clamp part and the movable flat plate part connected to the clamp part are almost the same. Since they are formed so as to be parallel to each other, it is possible to improve workability such as when bolting, as compared with the conventional one.
