Abstract
The utility model relates to a corrugated tube subassembly which is characterized in that a sealed evacuated cavity is formed by the connection of a right end fixed head, the corrugated tube and a left end bulb. A spring and a spring base are arranged in the cavity, and the spring is arranged on the spring base. When the corrugated tube subassembly is operated and the air tension outside the corrugated tube is changed, the corrugated tube subassembly is lengthened or shortened because of the air tension to form a balance with the spring force in the corrugated tube. The corrugated tube subassembly has the advantages that two covers are omitted and one spring base is added compared with the prior art; and the bulb and the corrugated tube are directly welded, so are the fixed head and the corrugated tube. The fitting technology is simplified, the manufactured cost is lowered, and fitting quality hidden problem is avoided. Therefore, the complex technology and the hidden problems on relative rotation between the bulb and the cover and between the end head and the cover are solved; and in addition, a clamping riveted structure in the prior art is easy to cause microcracks to the cover, and is easy to result in defects of corrugated tube evacuated leaking, and the like.
Description
Technical field:
The utility model relates to the bellows component of the pneumatic autocontrol valve of a kind of car air conditioner variable compressor.Belong to the pneumatic autocontrol valve attachment technique of car air conditioner variable compressor field.
Background technique:
The bellows component of the pneumatic autocontrol valve of existing car air conditioner variable compressor, its structure is: lid and bulb and termination could be welded with bellows after all needing riveted joint to be combined into assembly, complex process and bulb and lid, between termination and the lid hidden danger is in relative rotation arranged, and cramping riveted joint makes lid be easy to generate microscopic crack, and causes bellows to leak.
Summary of the invention:
The purpose of this utility model is intended to overcome existing in prior technology complex process and bulb and lid, relatively rotate between termination and the lid, the cramping riveted joint makes lid be easy to generate microscopic crack, easily causes defectives such as bellows leakage, proposes a kind of improved bellows component.
Technical solution of the present utility model: its structure is the vacuum cavity volume of right-hand member fixing head and a bellows and a sealing of left end bulb formation, and there are spring and spring seat in this cavity volume inside, and spring is contained on the spring seat.
Advantage of the present utility model: compared with prior art, save 2 lids, increase a spring seat; Bulb and bellows, fixing head and bellows all are direct welding.Assembly technology is simplified, and has not only reduced manufacture cost but also avoided hidden danger of quality in assembling.Thereby effectively overcome existing in prior technology complex process and bulb and lid, relatively rotated between termination and the lid, the cramping riveted joint makes lid be easy to generate microscopic crack, easily causes defectives such as bellows leakage.In this bellows component when work,, when the gas pressure outside the bellows changed, bellows component can elongate or shorten because of the effect of gas pressure, and with the spring force balance of bellows interior.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention.
Among the figure 1 is bulb, the 2nd, bellows, the 3rd, spring seat, the 4th, spring, the 5th, fixing head.
Embodiment:
Contrast accompanying drawing 1, its structure are that right-hand member fixing head 5 is joined successively with bellows 2 and left end bulb 1 and formed the vacuum cavity volume of a sealing, and there are spring 4 and spring seat 3 in this vacuum cavity volume inside, and spring 4 is contained on the spring seat 3.
In this bellows component when work,, when the gas pressure outside the bellows changed, bellows component can elongate or shorten because of the effect of gas pressure, and with the spring force balance of bellows interior.
Claims (1)
1, bellows component is characterized in that right-hand member fixing head (5) and bellows (2) and left end bulb (1) join to form the vacuum cavity volume of a sealing that there are spring (4) and spring seat (3) in this cavity volume inside, and spring (4) is contained on the spring seat (3).
