Description
Technical Field
The utility model relates to the technical field of shock absorption tubes, in particular to a shock absorption corrugated tube.
Background
When the motor of the compressor is started, the moment enables the compressor to swing to two sides, and the long-time running can lead to vibration cracking or cracking of the pipeline. Therefore, many refrigeration compressors now have shock tubes installed. The existing shock-absorbing corrugated pipe structure is generally provided with a corrugated pipe, a woven pipe, a pressing ring, a joint and other parts, so that a plurality of welding positions exist, and then leakage risks caused by cold joint, broken joint and other reasons are obviously increased, namely, potential leakage points are more. Thus, the shock absorbing bellows in the related art has a disadvantage in that the risk of leakage is large.
Therefore, it is necessary to provide a new shock absorbing bellows to solve the above-mentioned technical problems.
Disclosure of Invention
The utility model aims to overcome the technical problems and provide the shock absorbing corrugated pipe which can effectively reduce potential leakage points and has smaller leakage risk.
The utility model provides a shock absorbing corrugated pipe, which comprises a corrugated pipe, a steel wire braiding sleeve sleeved and fixed outside the corrugated pipe, a steel sleeve sleeved and fixed outside the steel wire braiding sleeve, a connecting sleeve connected and fixed at the end part of the corrugated pipe and a connecting pipe connected and fixed at one end, far away from the corrugated pipe, of the connecting sleeve, wherein the connecting sleeve is simultaneously connected and fixed with the corrugated pipe, the steel wire braiding sleeve and the steel sleeve, the outer diameter of the connecting sleeve is not smaller than the outer diameter of the steel sleeve, and the inner diameter of the connecting sleeve is smaller than the inner diameter of the corrugated pipe.
Preferably, the corrugated pipe is a stainless steel corrugated pipe, the steel wire braiding sleeve is a stainless steel wire braiding sleeve, the steel sleeve is a stainless steel sleeve, and the connecting sleeve is a stainless steel connecting sleeve.
Preferably, the connecting sleeve is provided with a step portion for connecting and fixing the steel sleeve, and the connecting sleeve has the largest outer diameter at the step portion.
Preferably, the connecting pipe is a red copper connecting pipe.
Preferably, a notch for plugging the connecting pipe is formed at one end of the connecting sleeve connected with the connecting pipe.
Preferably, the corrugated pipe, the steel wire braided sleeve and the steel sleeve are connected and fixed with the connecting sleeve in a welding mode.
Compared with the prior art, the shock absorbing corrugated pipe provided by the utility model has the advantages that one welding process is omitted, one leakage point is reduced, potential leakage points can be effectively reduced, and the leakage risk is smaller; one bushing is also reduced, the manufacturing cost is reduced, and the service performance of the product is improved.

Detailed Description
In order that the utility model may be readily understood, a more complete description of the utility model will be rendered by reference to the appended drawings. Preferred embodiments of the present utility model are shown in the drawings. This utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1-2, the present utility model provides a shock absorbing bellows, which comprises a bellows 1, a steel wire braiding sleeve 2 sleeved and fixed outside the bellows 1, a steel sleeve 3 sleeved and fixed outside the steel wire braiding sleeve 2, a connecting sleeve 4 connected and fixed at the end of the bellows 1, and a connecting pipe 5 connected and fixed at one end of the connecting sleeve 4 far away from the bellows 1.
The connecting sleeve 4 is simultaneously connected and fixed with the corrugated pipe 1, the steel wire braiding sleeve 2 and the steel sleeve 3, the outer diameter of the connecting sleeve 4 is not smaller than the outer diameter of the steel sleeve 3, and the inner diameter of the connecting sleeve 4 is smaller than the inner diameter of the corrugated pipe 1. Thereby, it is ensured that the connection sleeve 4 connects and fixes the bellows 1, the wire braid 2, and the steel sleeve 3 at the same time.
In this embodiment, the bellows 1 is a stainless steel bellows, the steel wire braid 2 is a stainless steel wire braid, the steel sleeve 3 is a stainless steel sleeve, and the connection sleeve 4 is a stainless steel connection sleeve.
In the present embodiment, the connection sleeve 4 is provided with a step portion 41 for connecting and fixing the steel sleeve 3, and the connection sleeve 4 has the largest outer diameter at the step portion 41. Therefore, the outer diameter of the connecting sleeve 4 is largest at one end close to the steel sleeve 3, and is relatively smaller at one end far away from the steel sleeve 3, so that the connecting sleeve 4 can be ensured to be connected and fixed with the corrugated pipe 1, the steel wire braided sleeve 2 and the steel sleeve 3 at the same time, and the material cost can be relatively reduced.
In this embodiment, the connection pipe 5 is a red copper connection pipe.
Specifically, one end of the connecting sleeve 4 connected with the connecting pipe 5 is provided with a notch 40 for inserting the connecting pipe 5. Thereby, the connection fixing effect of the adapter tube 5 and the connection sleeve 4 can be further improved.
More specifically, the bellows 1, the steel wire braiding sleeve 2 and the steel sleeve 3 are all connected and fixed with the connecting sleeve 4 in a welding mode.
Specifically, the corrugated pipe and the steel wire braiding sleeve 2 are pressed by the steel sleeve 3, the end face is arranged smoothly, and then the connecting sleeve is placed at the end face for welding. Therefore, one welding procedure is omitted, one leakage point is reduced, potential leakage points can be effectively reduced, and leakage risks are smaller; one bushing is also reduced, the manufacturing cost is reduced, and the service performance of the product is improved.
Compared with the prior art, the shock absorbing corrugated pipe provided by the utility model has the advantages that one welding process is omitted, one leakage point is reduced, potential leakage points can be effectively reduced, and the leakage risk is smaller; one bushing is also reduced, the manufacturing cost is reduced, and the service performance of the product is improved.
