Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a pipe cushion, and more particularly to a pipe cushion suitable for use in a pipe of a refrigeration system.

[Conventional technology]

FIG. 6 shows a buffer used in the conventional piping. FIG. 6 shows a perspective view of the cushioning body. The cushioning body 8 composed of the cylindrical body 9 has a hole 10 formed in the core portion to match the outer diameter of the pipe, and is attached to the pipe from the outer peripheral surface toward the center. A notch 11 is made over the entire length in the longitudinal direction. This buffer 8
As shown in FIG. 7, is attached to a pipe 20a through which vibration generated from a compressor or the like propagates in a refrigeration system, and prevents the pipe 20a or the like adjacent to the vibration from coming into contact with the pipe and causing an abnormal noise. , The vibration propagation is reduced.

[Problems to be solved by the device]

Conventionally, the shock absorber is attached to a pipe to prevent contact noise with adjacent pipes or the like, but in the tubular shape of the shock absorber, the entire longitudinal direction of the outer surface abuts on another pipe. For,
Abnormal noise is less reduced, and it is difficult to reduce vibration propagation.

The present invention is intended to provide a piping shock absorber that solves the above problems.

[Means for Solving the Problems]

The pipe cushioning body of the present invention is provided with projections formed on the outer peripheral surfaces of both ends of a cylindrical body having a notch from the outer peripheral surface toward the center, and the projections of the both end portions are formed at positions not facing each other. Is.

[Action]

In the pipe to which the shock absorber of the present invention is attached, when a projection formed at one end of the shock absorber comes into contact with another pipe,
The protrusion formed on the other end does not come into contact with the other pipe or the like. That is, the protrusion formed on one end of the buffer body is
Since the protrusions formed at the other end are not formed at positions facing each other, when one protrusion abuts on the pipe or the like, the other protrusion does not hit. Therefore, the propagation of vibration is remarkably reduced as compared with the case of contacting adjacent pipes or the like over the entire length in the longitudinal direction as in the conventional cushioning body. Further, since the portion where the protrusion contacts the pipe or the like is the head of the protrusion, it is possible to further reduce the vibration propagation.

〔Example〕

A first embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a front view of this embodiment, and FIG. 2 is a side view thereof.

The main body 2 of the shock absorber 1 is made of an elastic material such as natural or synthetic rubber, and is formed into a cylindrical shape having a hole diameter 15 that matches the diameter of the pipe to be attached. A notch 3 is formed from the outer peripheral surface of the main body 2 toward the center over the entire length in the longitudinal direction thereof. The cut 3 is provided for opening the cut 3 and inserting it into the pipe when the shock absorber 1 is attached to the pipe. The one end 4 of the main body 2 is formed with a protrusion 5a having a slightly rounded tip at an appropriate interval along the outer peripheral surface and an appropriate length in the longitudinal direction. .

To give an example of the dimensions of the main body 2, the inner diameter, that is, the target pipe diameter is 8 mm, the outer diameter is 18 mm, and the length is 18 mm.
A has a thickness of about 2.5 mm and projects 5 mm from the outer peripheral surface of the main body 2 and has a slightly rounded tip portion, and the length in the longitudinal direction is 5 mm.

The number of the protrusions 5a may be one or more, but in the present embodiment, eight protrusions 5a are formed at equal intervals of 45 ° along the outer peripheral surface. On the other hand, the other end 7 is also formed with a projection 5b having the same shape as the one end 4 and arranged in the same shape, but the projection 5a formed on the one end 4 is opposed to the projection 5a. No, both protrusions
5a and 5b are arranged offset from each other in the circumferential direction. That is,
As shown in FIG. 2 showing the side surface, the protrusions 5a and 5b are formed on the main body 2
Are formed at alternate positions in the circumferential direction.

In the present embodiment configured as described above, the notch 3 is opened and the shock absorber 1 is attached to the pipe 20 as shown in FIG. At this time, as shown in the figure, when one of the protrusions 5a of the one end 4 of the buffer 1 is brought into contact with the adjacent pipe 21, the protrusion 5b of the other end 7 opposes the protrusion 5a. Since it is not, it does not come into contact with the adjacent pipe 21. As described above, in the present embodiment, only one of the protrusions 5a and 5b at either end abuts on the adjacent pipe 21, and abuts on the adjacent pipe over the entire length in the longitudinal direction like a conventional buffer body. Never. Therefore, the vibration generated in the pipe 20 by the compressor in the refrigerating device or the like is less likely to be propagated to the other pipe 21 or the like as compared with the conventional shock absorbers which are in contact with the entire surface in the longitudinal direction. Vibration of piping etc. is reduced.

Further, in this embodiment, the head of one of the protrusions 5a or 5b abuts the adjacent pipe 21, and since the head has a rounded shape, the vibration propagated to the pipe 21 is prevented. It can be further reduced.

A second embodiment of the present invention will be described with reference to FIGS. 4 and 5.

FIG. 4 is a front view of the same embodiment, and FIG. 5 is a side view thereof.

This embodiment is different from the first embodiment in that one end portion 4
A protrusion formed on the other end 7 than the protrusion 5a formed on
The height of 5b is lowered.

This embodiment can achieve the same operation and effect as the first embodiment, but in addition to this, even if the distance between the adjacent pipes is different, the protrusion 5a, By appropriately selecting one of the 5b to abut on the adjacent pipe and attaching the buffer 1 to the pipe, it is possible to obtain an effect that it is not necessary to prepare another type of buffer.

[Effect of device]

In the pipe cushioning body of the present invention, the protrusions formed on the outer peripheral surfaces of both ends of the portion having the notch toward the center from the outer peripheral surface are formed at positions not facing each other, and one end of the adjacent pipe or the like is formed. Propagation of vibration can be reduced by abutting only the protrusions of the section.
