Description
Technical field
The utility model relates to a kind of linkage structure of component of freezer compressor, specifically the linkage structure of sealing between a kind of bellows that improves freezer compressor and silencing apparatus.
Background technique
At present, most of freezer compressors are provided with bellows and promote compressor and suck the purity of refrigeration agent, raising efficiency in the middle of sucking pipe and baffler.Existing bellows mainly contains two kinds of mounting types: the one, and the roundlet head end of bellows is arranged on silencing apparatus, outer nose circle is fitted on lower shell body, and this mode is subject to the variation of lower shell body fitting part radius of curvature and affects the gluing, sealing of bellows and lower shell body; The 2nd, the roundlet head end of bellows is arranged on sucking pipe, the sucking pipe end plane laminating of outer nose circle and silencing apparatus, and this mode needs the bellows of large-size, otherwise easily causes the outer nose circle of bellows to be inhaled into silencing apparatus.Also have in addition Partial shrinkage machine to adopt plastic tube to add spring and substitute bellows, although this mode can promote the sealing of bellows and silencing apparatus, cost is high, and part is installed relative complex.
Summary of the invention
Technical problem to be solved in the utility model is to propose that a kind of stickiness is good, easy for installation, cost is low, can improve the linkage structure of bellows and the silencing apparatus of freezer compressor sealing.
For solving the problems of the technologies described above, the bellows of a kind of freezer compressor of the utility model and the linkage structure of silencing apparatus comprise bellows and silencing apparatus, described bellows comprises roundlet head end, bellows segment and outer nose circle, described bellows segment has certain elastic telescopic amount, described outer nose circle has a faying surface and an inside crimp, described faying surface and crimp form draw-in groove jointly, and the air-breathing end face of described silencing apparatus snaps in described draw-in groove.
The bellows of above-mentioned a kind of freezer compressor and the linkage structure of silencing apparatus, described crimp length is 4～6mm, make the minimum diameter place of described draw-in groove than the little 1～2mm of the outside diameter of the air-breathing end face of described silencing apparatus, the maximum diameter place of described draw-in groove is than the large 1～2mm of the outside diameter of air-breathing end face.
The bellows of above-mentioned a kind of freezer compressor and the linkage structure of silencing apparatus, the Excircle machining of the air-breathing end face of described silencing apparatus has chamfering or is similar to the arc shaped surface of chamfering.
The bellows of above-mentioned a kind of freezer compressor and the linkage structure of silencing apparatus, the outside dimension of described bellows segment is less 1～2 times than described outer nose circle.
The utility model is owing to having adopted above-mentioned technical pattern, and the dual laminating of faying surface and crimp by bellows, has realized fitting tightly between bellows and silencing apparatus, and stickiness is good, has improved the gettering efficiency of compressor.Meanwhile, it also has easy for installation, low cost and other advantages, has effectively promoted the combination property of freezer compressor.
Accompanying drawing explanation
Fig. 1 is the linkage structure schematic diagram of the utility model bellows and silencing apparatus;
Fig. 2 is the assembly structure schematic diagram of the utility model bellows, silencing apparatus and lower shell body.
Embodiment
As shown in Figure 1, the linkage structure of a kind of bellows of the utility model and silencing apparatus comprises bellows 3 and silencing apparatus 1, and bellows 3 comprises outer nose circle 5, bellows segment 6 and roundlet head end 7, and the outside dimension of bellows segment 6 is less 1～2 times than outer nose circle 5; Roundlet head end 7 is enclosed within on the sucking pipe 4 of lower shell body 2 inside (please refer to Fig. 2); Bellows segment 6 has certain elastic telescopic amount, makes to keep between bellows 6 and silencing apparatus 1 certain sealing; Outer nose circle 5 has a faying surface 3a and an inside crimp 3b, and faying surface 3a and crimp 3b form draw-in groove 3c jointly, and the air-breathing end face 1a of silencing apparatus 1 can be stuck in draw-in groove 3c completely.Crimp 3b length is 4～6mm, guarantees that the minimum diameter place of draw-in groove 3c is than the little 1～2mm of outside diameter of the air-breathing end face 1a of silencing apparatus 1, and the maximum diameter place of draw-in groove 3c is than the large 1～2mm of the outside diameter of air-breathing end face 1a.The Excircle machining of the air-breathing end face 1a of silencing apparatus 1 has chamfering or is similar to the arc shaped surface 1b of chamfering, is convenient to the air-breathing end face 1a of silencing apparatus 1 to be stuck in completely in draw-in groove 3c.In the situation that compressor rocks, because air-breathing end face 1a sticks into draw-in groove 3c, and the bellows segment 6 of bellows 3 has certain extending amount, makes bellows 3 and silencing apparatus 1 keep certain sealing, guaranteed that air-breathing end face 1a is difficult for being shaken out.Inhaling under the operating mode of refrigeration agent, faying surface 3a can fit tightly on the air-breathing end face 1a of silencing apparatus 1 owing to being subject to suction; Under the operating mode of not inhaling refrigeration agent, due to the elastic reaction of bellows 3, can make the back side laminating of crimp 3b and air-breathing end face 1a, guarantee the purity of next suction refrigeration agent.Like this, the dual laminating of faying surface 3a and crimp 3b by bellows 3, has realized fitting tightly of bellows 3 and silencing apparatus 1, has improved the gettering efficiency of compressor.
Concrete mounting type of the present utility model is as follows: before the body that silencing apparatus 1 is housed is not put in lower shell body 2, bellows 3 is enclosed within on sucking pipe 4; After installing, body is installed in lower shell body 2, bellows 3 and silencing apparatus 1 automatic alignment, by promoting body, bellows segment 6 pressurizeds of bellows 3 to bellows 3 directions.Due to the chamfering 1b effect of the cylindrical of the elastic reaction of bellows segment 6 and the air-breathing end face 1a of silencing apparatus 1, can very easily air-breathing end face 1a be sticked into draw-in groove 3c.Even do not stick in draw-in groove 3c situation at air-breathing end face 1a, can press in the 1 direction extruding of the lateral of faying surface 3a silencing apparatus by finger or instrument, can very easily air-breathing end face 1a be sticked into draw-in groove 3c equally.
Compared with prior art, the utlity model has following advantage: one, by the faying surface of bellows and the dual laminating of crimp, bellows and silencing apparatus fit tightly, good airproof performance, has improved the gettering efficiency of compressor; Two, by promoting body or to silencing apparatus direction extruding bellows, installing more for convenience; Three, the outside dimension of the bellows segment of bellows is less 1～2 times than outer nose circle, saves rubber consumption, and does not adopt the parts such as spring, has saved cost of production.
