Abstract
The utility model discloses a kind of compressor round end plate-like bolt, including: bolt body (1), described bolt body (1) has light bar segment (2), thread segment (3) and bolt head (4), described bolt head (4) is hexagon cylinder, described hexagon cylinder top is sphere (5), by unique design, makes bolt head without seamed edge, avoid in collision process, compressor housing being caused damage, but also cushion collar can be increased thus further enhance protective capacities.
Description
Technical field
This utility model relates to fit sealing field, particularly relates to a kind of compressor round end plate-like bolt.
Background technology
Bolt is for fixing compressor cylinder block connector within the compressor, to ensure that compressor block cylinder block when up-down vibration the most directly clashes into compressor housing.As a rule, refrigerator rocking in transportation is easily caused body and bolt and comes in contact with housing, collides, easily generation impurity comes off and eventually enters into system, compressor is made normally to start, there is acute angle in the hexagonal head of general bolt, easily produce relatively crude iron bits granule with compressor housing when clashing into, head is that round end structure can have the generation relatively avoiding this kind of situation.
Summary of the invention
The purpose of this utility model is: overcome the above-mentioned problems in the prior art, a kind of compressor round end plate-like bolt is proposed, by unique design, make bolt head without seamed edge, avoid in collision process, compressor housing being caused damage, but also cushion collar can be increased thus further enhance protective capacities.
The purpose of this utility model is realized by following technical proposals:
A kind of compressor round end plate-like bolt, including: bolt body, described bolt body has light bar segment, thread segment and bolt head, and described bolt head is hexagon cylinder, and described hexagon cylinder top is sphere.
A kind of compressor round end plate-like bolt of the present utility model, the radius of curvature of described sphere is 3mm.
A kind of compressor round end plate-like bolt of the present utility model, described bolt head is provided with annular recess at light bar segment.
A kind of compressor round end plate-like bolt of the present utility model, described bolt head is cased with elastic protecting sleeve, and the opening of described protection set embeds in described annular recess.
A kind of compressor round end plate-like bolt of the present utility model, described bolt head is provided with buffer coat, and the thickness of described buffer coat is 0.3-1mm.
A kind of compressor round end plate-like bolt of the present utility model, described buffer coat is composed of the following components: the corundum 15-20 weight portion of 325-500 mesh, phthalic acid ester 37-85 weight portion, dialkyl polydimethylsiloxane 65-85 weight portion.
A kind of compressor round end plate-like bolt of the present utility model, described bolt is made up of 40Cr or SCM435.
According to technique scheme, the beneficial effects of the utility model are: overcome the above-mentioned problems in the prior art, a kind of compressor round end plate-like bolt is proposed, by unique design, make bolt head without seamed edge, avoid, in collision process, compressor housing is caused damage, but also cushion collar can be increased thus further enhance protective capacities, and cushion collar is elastic material, its opening shrinks in groove, thus strengthening anticreep ability, the coating of surface configuration is then possible to prevent maloperation will not cause damage when causing shock.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model a kind of compressor round end plate-like bolt；
Labelling in figure:
1-bolt body, 2-light bar segment, 3-thread segment, 4-bolt head, 5-sphere.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is further described.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
nullSuch as the embodiment that Fig. 1 is this utility model a kind of compressor round end plate-like bolt，A kind of compressor round end plate-like bolt，Including: bolt body 1，Described bolt body 1 has light bar segment 2、Thread segment 3 and bolt head 4，Described bolt head 4 is hexagon cylinder，Described hexagon cylinder top is sphere 5，The radius of curvature of described sphere 5 is 3mm，Described bolt head 4 is provided with annular recess at light bar segment 2，It is cased with elastic protecting sleeve on described bolt head 4，The opening of described protection set embeds in described annular recess，Described bolt head 4 is provided with buffer coat，The thickness of described buffer coat is 0.3-1mm，Described buffer coat is composed of the following components: the corundum 15-20 weight portion of 325-500 mesh，Phthalic acid ester 37-85 weight portion，Dialkyl polydimethylsiloxane 65-85 weight portion，Described bolt is made up of 40Cr or SCM435.
Owing to using technique scheme, the beneficial effects of the utility model are: overcome the above-mentioned problems in the prior art, a kind of compressor round end plate-like bolt is proposed, by unique design, make bolt head without seamed edge, avoid, in collision process, compressor housing is caused damage, but also cushion collar can be increased thus further enhance protective capacities, and cushion collar is elastic material, its opening shrinks in groove, thus strengthening anticreep ability, the coating of surface configuration is then possible to prevent maloperation will not cause damage when causing shock.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
