Abstract
The utility model discloses a kind of air compressor, comprise body, protecgulum, valve block group, cylinder, piston, connecting rod and live axle, described underpart sidewall is provided with protecgulum; Described live axle is connected with connecting rod mutually through organism sidewall, and connecting rod is connected with the piston be arranged in cylinder; Described cylinder is positioned at the top of body, and its top is provided with valve block group; Described piston is made up of piston only, spring and follow block, and described follow block is plugged in the inner chamber of piston only and also can moves axially; Described spring is arranged at piston only inner chamber, and piston only inner cavity top is fixed in its one end, the other end is fixed on follow block.The utility model not only solves the difficult replacing of air compressor live axle difficulty maintenance, and piston replacement frequency high cost is high, the problem that working life is low, and reduces cost, improves working efficiency.
Description
Technical field
The utility model relates to field of mechanical technique, has particularly related to a kind of air compressor.
Background technique
Air compressor is the device mechanical energy of prime mover being converted to gas pressure energy, is compressed-air actuated pressure generator.The live axle of air compressor is the parts more frequently that work in air compressor internal structure, relatively easily goes wrong and needs repairing.The casing of existing air compressor is all that employing is casting integrated shaping, and casing is generally enclosed construction, when live axle goes wrong, just needs, in casing punching, axial compression to be gone out, could keep in repair axle.Maintenance process is cumbersome, and each maintenance all can damage casing.
Meanwhile, the piston of air compressor is when moving reciprocatingly, and easy serious wear, so need often to change piston, uses for a long time, ceaselessly change piston, consume huge cost, too increase unnecessary working procedure.And piston in use, its top to bear gas pressure very large, traditional piston cavity roof is a smooth plane, when piston moves down, the inner chamber roof of piston bears and to upward pressure and due to the very thin thickness of inner chamber roof, piston roof is easily damaged, thus reduces the working life of piston.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model just there are provided a kind of air compressor, not only solves the difficult replacing of air compressor live axle difficulty maintenance, piston replacement frequency high cost is high, the problem that working life is low, and reduce cost, improve working efficiency.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of air compressor, comprises body, protecgulum, valve block group, cylinder, piston, connecting rod and live axle, and described underpart sidewall is provided with protecgulum; Described live axle is connected with connecting rod mutually through organism sidewall, and connecting rod is connected with the piston be arranged in cylinder; Described cylinder is positioned at the top of body, and its top is provided with valve block group; Described piston is made up of piston only, spring and follow block, and described follow block is plugged in the inner chamber of piston only and also can moves axially; Described spring is arranged at piston only inner chamber, and piston only inner cavity top is fixed in its one end, the other end is fixed on follow block.
As a kind of preferred version, above described protecgulum, be provided with resuscitation apparatus.
As a kind of preferred version, described piston also comprises jump ring, and the intracavity sidewall of described piston only is provided with draw-in groove, and described jump ring is plugged in draw-in groove to support follow block.
As a kind of preferred version, the end that described connecting rod is connected with piston is uniformly distributed at least four keys, and piston is uniformly distributed at least four keyways, and described key and keyway match.
Compared with prior art, the beneficial effects of the utility model:
1., when needing to keep in repair the live axle in air compressor body, open protecgulum and axle is taken out maintenance, operating process is simple, decreases the injury to air compressor body, improves working efficiency;
2. be provided with resuscitation apparatus, better can discharge and alter from piston head the waste gas got off, keep the air pressure in body to be equal to extraneous pressure, pneumatics function long-time continuous is operated;
3. the novel piston adopted, not only saves the time changing piston, provides cost savings, and add the working life of piston.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of piston in the utility model;
Fig. 3 is the A place enlarged view of Fig. 2;
Fig. 4 is the worm's eye view of piston in the utility model.
Embodiment
Below with reference to specific embodiment, the technological scheme that the utility model provides is described in detail, following embodiment should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.
Embodiment:
As shown in Figure 1 and Figure 2, a kind of air compressor, comprises body 1, protecgulum 2, valve block group 3, cylinder 4, piston 5, connecting rod 6 and live axle 7, and described body 1 lower sides is provided with protecgulum 2; Described live axle 7 is connected with connecting rod 6 mutually through body 1 sidewall, and connecting rod 6 is connected with the piston 5 be arranged in cylinder 4; Described cylinder 5 is positioned at the top of body 1, and its top is provided with valve block group 3; Described piston 5 is made up of piston only 51, spring 52 and follow block 53, and described follow block 53 is plugged in the inner chamber of piston only 51 and also can moves axially; Described spring 52 is arranged at piston only 51 inner chamber, and piston only 51 inner cavity top is fixed in its one end, the other end is fixed on follow block 53; Resuscitation apparatus 8 is provided with above described protecgulum.As shown in Figure 3, described piston also comprises jump ring 54, and the intracavity sidewall of described piston only 51 is provided with draw-in groove 55, and described jump ring 54 is plugged in draw-in groove 55 to support follow block 53.As shown in Figure 4, the end that described connecting rod 6 is connected with piston 5 be uniformly distributed at least four keys (due in figure for non-installment state, therefore do not mark), piston 5 is uniformly distributed at least four keyways 56, and described key and keyway 56 match.During concrete enforcement, when needing to keep in repair the live axle 7 in air compressor body, open protecgulum 2 and axle is taken out maintenance, operating process is simple, decreases the injury to air compressor body 1, improves working efficiency; Also be provided with resuscitation apparatus 8, better can discharge and alter from piston 5 top the waste gas got off, keep the air pressure in body 1 to be equal to extraneous pressure, pneumatics function long-time continuous is operated; Further, the novel piston 5 of employing, not only saves the time changing piston 5, provides cost savings, and add the working life of piston 5.
Finally it should be noted that, above embodiment is only in order to illustrate the technical solution of the utility model and non-limiting technological scheme, those of ordinary skill in the art is to be understood that, those are modified to the technical solution of the utility model or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present utility model.
