Problems solved by technology

However, in the past, when the shock absorber was formed, the two ends of the bellows were welded together with the stainless steel mesh sleeve and the outer tube by brazing, and cracks would appear in the bellows during the welding process, which was the main cause and problem of defective products.

Embodiment Construction

[0009] Below in conjunction with accompanying drawing, the present invention will be further described:

[0010] The shock absorber includes a bellows 4, a stainless steel net sleeve 3, two inner clamp tubes 2 of the net sleeve, two outer clamp tubes 1 of the net sleeve, and two outer pipe joints 5. The two inner clamping tubes 2 of the mesh sleeves are respectively welded to the two ends of the bellows 4, the bellows 4 and the inner clamping tubes 2 of the two mesh sleeves are covered with a stainless steel mesh sleeve 3, and the outer clamping tubes of the two mesh sleeves 1 and respectively corresponding outer jackets on the two inner clamping tubes 2 of the net sleeves, so that the two ends of the stainless steel net sleeves 3 are placed between the outer clamping tubes 1 of the net sleeves and the inner clamping tubes 2 of the net sleeves. The outer diameter of the inner pinch tube 2 of the net sleeve is provided with annular grooves 7 of different depths and widths, and ...

Abstract

The invention relates to a vibration absorber. The vibration absorber is characterized by comprising a corrugated pipe, a stainless steel net cover, two inner net cover clamping pipes, two outer net cover clamping pipes and two external pipe joints, wherein the two inner net cover clamping pipes are welded to the two ends of the corrugated pipe respectively, the corrugated pipe and the two inner net cover clamping pipes are sleeved with the stainless steel net cover, and the two outer net cover clamping pipes are correspondingly arranged on grooves in the two inner net cover clamping pipes respectively in a sleeving mode to enable the two ends of the stainless steel net cover to be located between the outer net cover clamping pipes and the inner net cover clamping pipes; the stainless steel net cover is pressed onto the inner net cover clamping pipes when the outer net cover clamping pipes and the inner net cover clamping pipes are in press fit, and the two external pipe joints are welded to the inner net cover clamping pipes at two ends respectively. Due to the fact that the inner net cover clamping pipes are additionally arranged between the corrugated pipe and the external pipe joints, the inner net cover clamping pipes and the outer net cover clamping pipes are in press fit through annular grooves and annular bosses to firmly press the two ends of the stainless steel net cover, the vibration absorber has the advantages of being high in supporting strength, capable of avoiding weld cracks and long in service life.

Description

technical field [0001] The invention relates to a shock absorber. Background technique [0002] Existing air conditioners, dehumidifiers, and refrigerators use aluminum tubes or copper tubes for refrigerant pipelines. The vibration of the refrigeration compressor may resonate with the vibration of the refrigeration pipeline, causing people to be concerned about the resonance damage caused by the vibration. concern. Therefore, in order to suppress the resonance of the pipeline system, a bellows shock absorber is usually installed in the middle of the pipeline system to make the bellows absorb the vibration. The bellows of the compressor connected with the bellows will expand and contract properly during the repeated compression of the refrigerant. It absorbs shock and becomes a structure that prevents resonance. However, if the thickness of the bellows is too thick, its flexibility will be lost, resulting in insufficient shock absorption, and will be damaged in a short time...
