Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention consists of a resin clamp for piping for vibration suppression, etc., which holds a plurality of pipes installed in an automobile etc. in the air, and a combination of the resin clamp for piping and a wedge. This invention relates to a resin clamp device for piping.

0002

[Prior Art] Generally, various types of piping are installed in automobiles, but the piping vibrates due to the vibrations of the automobile, resulting in a decrease in the degree of coupling of the joints, interference between the piping, and shortening of the life of the piping. In order to prevent this, resin clamps for pipes are used to hold the pipes in the air and suppress pipe vibrations caused by automobile vibrations.

Conventionally, as shown in FIG. 11, this type of resin clamp for piping has a plurality of pairs of first and second clamp parts 3 and 4 extending from a common base 2 in directions 180° different from each other. The frontage portions 3a and 4a of the first and second clamp portions 3 and 4 were opened in directions 180° different from each other.

However, in the above-mentioned conventional resin clamp for piping, the pipe holding performance and the ease of pipe insertion work are in a contradictory relationship. In other words, in order to effectively prevent pipes from coming off and improve pipe holding performance, the width of the frontage should be narrowed and the holding part should be It is necessary to increase the thickness of the pipe and make the material harder, but if such measures are taken to ensure pipe retention performance, the insertion force (the load applied when inserting the pipe) will increase. ,
This makes the tube insertion work difficult. On the other hand, if an attempt is made to make the tube insertion work easier by reducing the insertion force, the removal force will be reduced, which will not sufficiently prevent the tube from coming off, resulting in a decrease in tube holding performance. .

The present invention solves the above-mentioned problems, and its first object is to provide a resin clamp for piping that can simultaneously satisfy pipe holding performance and ease of pipe insertion work.

Furthermore, the present invention aims to increase the thrust force (the load applied when the resin clamp for piping moves in the axial direction of the pipe being held), which is another type of pipe holding performance. A second object of the present invention is to provide a resin clamp device for piping, which is a combination of a resin clamp for piping and a wedge, and can satisfy both holding performance and ease of pipe insertion work.

[0007]

[Means for Solving the Problems] In order to solve the first problem, a first resin clamp for piping according to the present invention has first and second pipes extending from a common base in directions 180° different from each other. In the resin clamp for piping, which has two clamp parts, and each frontage of the first and second clamp parts opens in directions different from each other by 180 degrees, a slit is formed in the common base part along the axial direction of the pipe. It is characterized by what it did.

In order to solve the first problem, the second resin clamp for piping according to the present invention has a pair of first resin clamps extending from a common base in directions 180° different from each other.
, in a resin clamp for piping having a plurality of second clamp parts, each of which has openings in directions different from each other by 180 degrees, the common base being along the axial direction of the pipe. It is characterized by having a slit formed therein.

Furthermore, in order to solve the above-mentioned second problem, a resin clamp device for piping consisting of a combination of a resin clamp for piping and a wedge according to the present invention is provided with a resin clamp for piping that combines the resin clamp for piping and a wedge. It is characterized by comprising a resin clamp for piping, and a wedge that is fitted into the slit after piping is connected to the resin clamp for piping.

[Operations and Effects of the Invention] According to the first resin clamp for piping and the second resin clamp for piping according to the present invention, the clamp portion can be deformed so that the interval between the slits becomes narrower during pipe insertion work. Therefore, the frontage can be expanded easily,
Therefore, since the insertion force is small, the tube insertion operation becomes easier. Furthermore, when the pipe is about to come off, the clamp part can be deformed so that the interval between the slits is widened, so the frontage part is difficult to expand, and therefore, the removal force is large, so that pipe holding performance can be ensured. Therefore, it is possible to simultaneously satisfy tube holding performance and ease of tube insertion work.

Furthermore, according to the resin clamp device for piping which is a combination of a resin clamp for piping and a wedge according to the present invention, the clamp part can be deformed so that the interval between the slits becomes narrower during pipe insertion work. Therefore, the opening can be easily expanded, and the insertion force is therefore small, making the tube insertion work easier. Further, since the wedge deforms the clamp portion toward the pipe and increases the degree of compression against the pipe, both the removal force and the thrust force increase, further improving the pipe holding performance. Therefore,
It is possible to simultaneously satisfy tube holding performance and ease of tube insertion work.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

■First embodiment (FIGS. 1 to 5) This embodiment consists of a first resin clamp 1 for piping according to the present invention, and a combination of the first resin clamp 1 for piping and a wedge 7. This invention relates to a resin clamp device for piping.

1) First resin clamp for piping (FIGS. 1 to 3) As shown in FIG. It consists of 5. The first and second clamp parts 3 and 4 are formed extending from the common base 2 in directions 180 degrees different from each other, and
The respective frontage parts 3a and 4a of the second clamp parts 3 and 4 are 1
They open in 80° different directions. The slit 5 is formed in the common base 2 along the axial direction of the pipe 6.

In the pipe resin clamp 1 having the above structure, the clamp parts 3 and 4 are deformed so that the interval between the slits 5 becomes narrower, as shown in FIG. 2, during the pipe insertion operation. Therefore, the openings 3a, 4a can be easily expanded, and the insertion force is therefore small, making the tube insertion work easier.

Further, in the pipe resin clamp 1 having the above structure, when the pipe 6 is about to come off, the clamp parts 3 and 4 are deformed so that the interval between the slits 5 becomes wider, as shown in FIG. For this reason, the openings 3a, 4a are difficult to expand, and therefore, the removal force is large, so that pipe holding performance can be ensured.

[0017] Therefore, the tube holding performance and the ease of tube insertion can be satisfied at the same time.

2) Wedge (FIGS. 4 and 5) This wedge 7 is a wedge that is fitted into the slit 5 after the piping is connected to the first resin clamp for piping 1 having the above structure, and the handle 7a
is formed.

Therefore, since the wedge 7 increases the degree of compression of the clamp parts 3 and 4 against the pipe 6, both the removal force and the thrust force increase, and the pipe holding performance is further improved.

■Second Embodiment (FIGS. 6 to 10) This embodiment is a second piping resin clamp 1 according to the present invention, and
This relates to the combination of the second resin clamp 1 for piping and the wedges 7 and 8.

(FIG. 8) As shown in FIG. 6, this resin clamp 1 for piping consists of a common base 2, a clamp portion 9, and two slits 5 and 10. The clamp part 9 includes a pair of first and second clamp parts 3,
4 are arranged in parallel (three in FIG. 6), the first and second clamp parts 3 and 4 are formed extending from the common base 2 in directions 180° different from each other, and the first and second The respective frontage parts 3a and 4a of the clamp parts 3 and 4 are 180 degrees apart from each other.
It opens in different directions. The slits 5 and 10 are formed on both side surfaces of the common base 2 along the axial direction of the pipe 6.

In the pipe resin clamp 1 having the above structure, the clamp portion 9 is deformed so that the distance between the slits 5 and 10 becomes narrower, as shown in FIG. 7, during the pipe insertion operation. Therefore, the openings 3a, 4a can be easily expanded, and the insertion force is therefore small, making the tube insertion work easier.

Furthermore, in the pipe resin clamp 1 having the above structure, when the pipe 6 is about to come off, the clamp portion 9 deforms so that the interval between the slits 5 becomes wider, as shown in FIG. For this reason, the openings 3a, 4a are difficult to expand, and therefore, the removal force is large, so that pipe holding performance can be ensured.

[0024] Therefore, the tube holding performance and the ease of tube insertion can be satisfied at the same time.

2) Wedges (FIGS. 9 and 10) These wedges 7 and 8 are wedges that are fitted into the slits 5 and 10 after the piping is connected to the first resin clamp 1 for piping having the above structure, and the handles 7a and 8a are formed.

Therefore, since the wedges 7 and 8 increase the degree of compression of the clamp portion 9 against the pipe 6, both the removal force and the thrust force increase, further improving the pipe holding performance.
