Embodiment 1

[0066] like figure 1 and figure 2 As shown, the shock absorber tube 100 of this embodiment includes: a corrugated tube 1, a first connecting ring 2, a second connecting ring (not shown in the figure), a bracket 3, a flexible rope 4, a first connecting tube 51, a second The connecting pipe 52 , the transition pipe 53 and the flexible protective sleeve 7 .

[0067] like figure 1 and figure 2As shown, the left and right ends of the shock absorber 100 are arranged symmetrically, the bellows 1 is arranged inside the shock absorber 100 , and the central axis of the bellows 1 is flush with the central axis of the shock absorber 100 . The bellows 1 has a first end 11 and a second end (not shown in the figure), the right end of the first connecting ring 2 (such as figure 1 The right end shown) is welded to the first end 11 of the bellows 1, and the left end of the second connecting ring (such as figure 1 The left end shown) is welded to the second end of the bellows 1.

Embodiment 2

[0075] The structure of this embodiment is substantially the same as that of Embodiment 1, wherein the same components use the same reference numerals, such as figure 2 As shown, the only difference is that the transition pipe 53 is integrated with the first connecting pipe 51. The transition pipe 53 includes a straight pipe section 531 and a gradually expanding pipe section 532. The peripheral wall is welded and connected, the other end of the straight pipe section 531 is connected with the expanding pipe section 532, and the other end of the expanding pipe section 532 is connected with the first connecting pipe 51, in the direction from the first connecting pipe 51 to the first connecting ring 2, gradually The cross-sectional area of ​​the expanded pipe section 532 gradually increases. Thus, the structure of the shock absorber 100 is simplified, and the assembly process of the shock absorber 100 is simplified.

Embodiment 3

[0077] The structure of this embodiment is substantially the same as that of Embodiment 1, wherein the same components use the same reference numerals, such as image 3 As shown, the only difference is that the bracket 3 includes a fixed part 31 and four connecting parts 32 arranged at regular intervals on the outer peripheral wall of the fixed part 31, and two adjacent connecting parts 32 and the inner peripheral wall of the first connecting ring 2 or The inner peripheral walls of the second connecting ring jointly define an escape hole 34 . Therefore, the structure of the bracket 3 is relatively simple, which is convenient for production.

[0078] Refer below Figure 1-Figure 4 An air conditioner according to an embodiment of the present invention will be described.

[0079] An air conditioner according to an embodiment of the present invention includes the above-mentioned shock absorber tube 100 .

[0080] According to the air conditioner of the embodiment of the present...

Abstract

The invention discloses a vibration absorber and an air conditioner comprising the same. The vibration absorber comprises a corrugated pipe, a first connecting ring, a second connecting ring, two supports and a flexible rope, wherein the corrugated pipe comprises a first end and a second end; one end of the first connecting ring is connected with the first end; one end of the second connecting ring is connected with the second end; the two supports are connected with the inner peripheral wall of the first connecting ring and the inner peripheral wall of the second connecting ring, and yield holes for fluids to pass through are formed in the supports; the flexible rope is arranged in the corrugated pipe, and two ends of the flexible rope are connected with the two supports respectively. According to the vibration absorber, the flexible pipe is arranged in the corrugated pipe, the two ends of the flexible rope are connected with the two supports respectively, and when the inside of the vibration absorber deforms under pressure, the flexible rope can restrain the elongation of the vibration absorber in the axial direction and still has higher flexibility when the vibration absorber reaches the largest deformation so as to play the better vibration isolation effect.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a shock absorber tube and an air conditioner with the same. Background technique [0002] With the development of frequency conversion air conditioner technology, the operating frequency range of the compressor is wider and wider, and the vibration amplitude of the piping is also increasing. As a result, the vibration stress of the piping exceeds the limit at certain operating frequencies, affecting the normal operation of the air conditioner. [0003] In the related art, a shock absorber pipe is connected in series in the piping to prevent the mechanical vibration of the compressor body from being transmitted to the air return pipe or the enthalpy-increasing injection pipe. The shock absorber includes a bellows, a net sleeve and a connector. When the inside of the shock absorber is under pressure, the net sleeve is in a tight state, which tends to reduce the overall fle...
