Abstract
The utility model belongs to the field of piston type air compressors and particularly relates to a piston type air compressor provided with a front cover. The piston type air compressor comprises a box body and further comprises the front cover. The front cover comprises a cover bottom and a cover wall, the cover bottom and the cover wall are integrally formed, a plurality of fixed supporting lugs are arranged on the edge of the cover bottom, threaded through holes are formed in the fixed supporting lugs, and the cover wall is a circular-ring cylindrical cover wall. A through hole is formed in the front end of the box body, and the through hole is matched with the cover wall. Threaded holes are formed in the portions, corresponding to the threaded through holes, of the front end of the box body. The piston type air compressor further comprises screws. The screws fix the front cover and the box body through the threaded through holes and the threaded holes. A respirator is arranged on the cover bottom. When an inner shaft of the box body needs to be maintained, a worker can maintain the inner shaft by directly unscrewing the screws, opening the front cover and taking out the inner shaft instead of punching holes in the front end of the box body, therefore, the operation process is simple and quick, and damage to the box body is reduced.
Description
Technical field
The utility model belongs to the piston type air compressor field, relates in particular to a kind of piston type air compressor that is provided with protecgulum.
Background technique
Air compressor is the mechanical energy of prime mover to be converted to the device of gas pressure energy, is compressed-air actuated pressure generator.Air compressor crank is the parts more frequently of working in the air compressor internal structure, relatively easily goes wrong and needs repairing.The casing of existing air compressor is all to adopt casting integrated moulding, and the casing front end is generally enclosed construction, when bent axle goes wrong, just need to axial compression be gone out in the punching of casing front end, could keep in repair axle.Maintenance process is cumbersome, and each maintenance all can damage casing.
The model utility content
The purpose of this utility model is to solve the deficiencies in the prior art part, does not need with the punching of air compressor front end the piston type air compressor that is provided with protecgulum that directly axle in casing is overhauled by opening protecgulum and provide a kind of.
The purpose of this utility model solves by following technical proposal:
A kind of piston type air compressor that is provided with protecgulum, comprise casing, it is characterized in that: also include protecgulum, described protecgulum comprises and covers the end and tegmental wall, at the bottom of described lid and tegmental wall one-body molded, described lid base, along being provided with some fixedly journal stirrups, has tapped through hole on described fixedly journal stirrup, and described tegmental wall is annulus cylindricality tegmental wall; Described casing front end has through hole, and described through hole and tegmental wall match; Have tapped hole on described casing front end and the corresponding position of tapped through hole.
The utility model also includes screw, and described screw is fixed protecgulum and casing by tapped through hole and tapped hole.
Be provided with resuscitation apparatus at the bottom of lid described in the utility model.
Compared to the prior art the characteristics and the beneficial effect that the utlity model has are:
1, when needs to casing in axle while keeping in repair, directly turn on screw, open protecgulum axle taken out maintenance, operating process Simple fast.
2, do not need the punching to the casing front end to keep in repair, reduced the injury to casing.
3, increased a resuscitation apparatus and can discharge better from piston head and alter the waste gas that gets off, kept the air pressure in crankcase body to be equal to extraneous pressure, made the running of pneumatics function long-time continuous.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model protecgulum place structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of piston type air compressor that is provided with protecgulum comprises casing 1, also include protecgulum 2, described protecgulum 2 comprises and covers the end 3 and tegmental wall 4, at the bottom of described lid 3 and tegmental wall 4 one-body molded, at the bottom of described lid, 3 edges are provided with some fixedly journal stirrups 5, have tapped through hole 6 on described fixedly journal stirrup 5.Described tegmental wall 4 is annulus cylindricality tegmental wall 4.
Casing 1 front end described in the utility model has through hole 7, and described through hole 7 and tegmental wall 4 match.Have tapped hole 8 on described casing 1 front end and the corresponding position of tapped through hole 6.Also include screw 9, described screw 9 is fixing with protecgulum 2 and casing 1 by tapped through hole 6 and tapped hole 8.When needs keep in repair the interior axle of casing 1, directly turn on screw 9, open protecgulum 2 axle is taken out maintenance, operating process Simple fast.
At the bottom of lid described in the utility model, 3 are provided with resuscitation apparatus 10, usually only has a resuscitation apparatus 10, the utility model has increased a resuscitation apparatus 10 at lid at the end 3, can discharge better from piston head and alter the waste gas that gets off, keep the air pressure in crankcase body 1 to be equal to extraneous pressure, make the running of pneumatics function long-time continuous.
