The heat exchanger → piping → condenser → piping → compressor and circulation flow path system are configured. In such a circulation flow path system, normally, the refrigeration cycle piping is arranged in the space only by the self-supporting property of the piping itself and is not fixed by metal fittings or the like, so vibration of the compressor is easily transmitted to each part of the piping, Vibrate. Such vibration causes adverse effects such as generation of cracks in the pipe, especially in the welded portion of the pipe.

Therefore, the vibration preventing tool shown in FIGS. 5A and 5B is attached to an arbitrary portion of the pipe. The vibration preventing tool a of FIG. 5 (A) is made of butyl rubber and has a self-adhesive property, and is attached by folding it in two with the pipe h sandwiched from inside in a rectangular shape in plan view. It is a thing. The vibration preventive tool b shown in (B) is a molded product made of powdery lead-containing CR rubber, and cuts b2 from the insertion part b1 of the pipe h by secondary processing.
And the insertion part b is opened from the cut b2.
After passing the pipe h through 1, it is fastened and fixed by a band or a wire b3. These vibration-preventing tools a and b mainly serve as weights and increase the weight of the pipes to stop vibrations. The specific gravity is adjusted by using powder of lead or the like made of synthetic resin or rubber. It was impossible to change the weight after molding, because the specific gravity was determined by filling and kneading in the inside and the amount thereof.

[0004]

According to the present invention, the overall weight can be increased (the apparent specific gravity is increased) without changing the overall size, and the overall weight can be easily changed even after molding. It is intended to provide a weight-mounting type vibration preventing tool for a compressor type refrigeration cycle pipe that can be used.

The fitting projection 11 and the fitting recess 21 may be shaped so as to fit into each other so as not to easily come off. In this embodiment, the fitting projection 11 has a distal end portion 11b rather than the base end portion 11a. Is getting bigger. The fitting concave portion 21 has a shape corresponding to the fitting projection 11, and the deep portion 21b is made larger than the shallow portion 21a, and the base end portion 11a of the fitting protrusion 11 is attached to the shallow portion 21a.
The tip portion 11b is fitted in the deep portion 21b. Then, the tip end portion 11b of the fitting projection 11 is tapered toward the tip thereof, so that the fitting projection 21 is easily fitted into the fitting concave portion 21 and is hard to come off.

In the first portion 1 and the second portion 2, respectively,
Cylindrical weight mounting holes 13 and 23 are provided. Then, weights 14 and 24 made of metal having a large specific gravity such as iron and lead are mounted in the mounting holes 13 and 23. The mounting holes 13 and 23 of the weight are formed linearly in parallel with the recesses 12 and 22 for inserting the pipe, and both ends are open. Weight 14, 24
Has a cylindrical shape and is press-fitted from one end of the mounting holes 13 and 23. When changing the weight, a new replacement weight (not shown) is attached to the attachment holes 13 and 23 by sticking the ends of the weights 14 and 24 already attached.
Then, the mounted weights 14 and 24 are pushed out from the mounting holes 13 and 23, and new weights are mounted to the mounting holes 13 and 23, and the weights can be easily replaced. It should be noted that the weight may be approximately equal to the total length of the mounting holes 13 and 23, but if the weight is short, the total weight can be changed without changing the specific gravity of the weight. Then, by mounting several short weights in the mounting holes 13 and 23,

The rubber or the synthetic resin may be filled and mixed with powder such as lead having a large specific gravity, as in the conventional case. The hardness of rubber or synthetic resin can be freely changed, but in this embodiment, the connection portion 3, the peripheral portions of the mounting holes 13 and 23, the peripheral portions of the pipe insertion concave portions 12 and 22, and the fitting concave portion 21. The peripheral portion of the shallow portion 21a is made softer and more elastic than the other portions. In the figure, a small dot is attached to a portion that is softer and has higher elasticity than other portions. That is, by making the connecting portion 3 soft and highly elastic, the opening / closing operation of the first portion 1 and the second portion 2 is facilitated. Further, by making the areas around the mounting holes 13 and 23 soft and highly elastic, it becomes easy to press-fit or replace a weight (not shown). Further, by making the peripheral portions of the pipe insertion recesses 12, 22 soft and highly elastic, the pipe h can be made to be the pipe insertion recesses 12, 22.
Even if the pipe h is slightly larger than the above, the pipe h can be sandwiched without difficulty. Fitting recess 21
By making the peripheral portion of the shallow portion 21a of the above-mentioned soft and large in elasticity, even if the tip portion 11b of the fitting projection 11 is made considerably larger than the shallow portion 21a of the fitting concave portion 21, the fitting can be reasonably performed. It was done like this. It is not necessary to make all of these parts softer and more elastic than the other parts. For example, only the parts around the mounting holes 13 and 23 are softer and more elastic than the other parts. Good. In addition, the first portion 1, the second portion 2 and the connecting portion 3
The whole and may be soft and highly elastic. Alternatively, the entire fitting projection 11 or the tip portion 11b thereof may be made hard, and the other portions may be made soft and have high elasticity.

The first portion 1, the second portion 2 and the connecting portion 3 are
These can be integrally molded. Although the molding method at that time is arbitrary, by molding the molded product formed by extrusion molding into an appropriate length,
It can be mass-produced at low cost. Moreover, by this extrusion molding, the connecting portion 3 is formed over the entire length from one end of both parts 1 and 2 to the other end, and the pipe insertion recesses 12 and 22 are formed from one end of both parts 1 and 2 to the other end. Since it is formed over the entire length of and parallel to the above-mentioned connecting portion 3, positioning when the pipe h is sandwiched becomes easy. Further, the fastening force after the fitting can be increased by the lengthening of the fitting portion, and it can be easily prevented from coming off. In addition, as described above, the mounting hole 1
By press-fitting the weights into the pipes 3 and 23, the holding of the pipes 12 and 22 for inserting the pipes and the fixing of the fitting projections 11 and the fitting recesses 21 by the fitting become stronger.

Next, FIG. 2 shows another embodiment. In this embodiment, the shape of the first portion 1 and the second portion 2 is a substantially cubic shape, and the weight mounting hole 13 is provided. , 23 are formed in the lateral direction and are not formed in parallel with the pipe insertion recesses 12, 22, and the fitting projection 11 and the fitting recess 21 are shorter than the entire length of the first portion 1 and the second portion 2. The point is different from the previous embodiment.
