[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fitting type vibration preventing tool for a compressor type refrigeration cycle pipe such as an air conditioner, a cooler, a refrigerator and a dehumidifier.

[0002]

[Prior art]

 Generally, in a compressor-type cooling system, the refrigeration cycle piping constitutes a compressor → piping → heat exchanger → piping → condenser → piping → compressor and circulation flow path system. 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, etc., so vibration of the compressor is easily transmitted to each part of the piping, Vibrate. Such vibrations have an adverse effect on the pipes, especially cracks in the pipe welds.

Therefore, it has been practiced to attach a vibration preventing tool shown in FIGS. 5A and 5B to an arbitrary portion of the pipe. These vibration-preventing tools mainly play the role of a weight, and increase the weight of the pipe to stop the vibration. The vibration-preventing tool a shown in FIG. 5A is made of butyl rubber and has a self-adhesive property. The vibration-preventing tool a is self-adhesive by folding the pipe h inside and extending it in a rectangular shape in plan view. Although it is attached by adhering the surfaces having adhesiveness to each other, the surface having self-adhesiveness may stick to an unexpected place during attachment. Also, if you have to remove it by mistake because it was installed in the wrong place, it is difficult to peel off the sticky surfaces, and if you forcibly remove it, you cannot use it again. Occurs. Next, the vibration prevention tool b shown in (B) is a molded product made of powdery lead-containing CR rubber, in which the cut b2 is formed by secondary processing from the insertion part b1 of the pipe h. After opening from the cut b2 and passing the pipe h through the insertion part b1, it is fastened and fixed by a band or a wire b3. This vibration preventive tool b cannot be fixed with one touch since it is necessary to tighten it with the band or wire b3 after mounting the vibration preventive tool on the pipe h, and the band or wire b3 cannot be fixed at the time of fixing work. It may be dropped. Further, in adjusting the specific gravity of these vibration preventing tools a and b, powders such as lead are filled in a synthetic resin or rubber and kneaded, and the specific gravity is determined by the amount, so the weight is changed after molding. I couldn't do that.

A fitting protrusion 11 and a fitting recess 21 are formed. Piping insertion recesses 12 and 22 are formed between the connecting portion 3 of the members 1 and 2 and the fitting protrusion 11 and the fitting recess 21. The pipe insertion recesses 12 and 22 are formed in the pipe insertion recesses 12 and 22, respectively. By arranging the pipe h and fitting the fitting projection 11 into the fitting recess 21, the first portion 1 and the second portion 2 can be fixed with one touch with the pipe h interposed therebetween. It is a thing. 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 rather than a base end portion 11a. 11b is increased. The fitting recess 21 has a shape corresponding to the fitting projection 11, and the depth 21b is made larger than the shallow portion 21a, and the base end portion 11a of the fitting projection 11 is located in the shallow portion 21a and the tip portion is located in the deep portion 21b. 11b is fitted. 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 recess 21 and is hard to come off.
