Abstract
The utility model relates to a top-hoisted connecting structure of a cylinder cover and a valve plate component. A through hole is formed in the center of the cylinder cover. A top-hoisted screw is arranged in the through hole. A threaded hole is formed in the center of the valve plate component. The valve plate component ceiling is connected to the lower end port of the cylinder cover through a matching structure in a top-hoisted mode, wherein the matching structure is connected to the threaded hole in the center of the valve plate component in a threaded mode through the lower end of the top-hoisted screw. A cylinder cover spacer is further arranged between the lower end port of the cylinder cover and the valve plate component. The cylinder cover spacer and the valve plate component are connected to the lower end port of the cylinder cover in a top-hoisted mode through the matching structure which is connected to the threaded hole in the center of the valve plate component in the threaded mode through the lower end of the top-hoisted screw. According to the connecting structure of the cylinder cover and the valve plate component ceiling, the connecting structure of the cylinder cover and the valve plate component is slightly improved, the structure that the valve plate component is connected to the center of the cylinder cover through the top-hoisted screw in a top-hoisted mode is additionally arranged in the center of the cylinder cover and fixed on the cylinder cover opening portion together with the cylinder cover, so that the strength of the valve plate component is improved, the phenomenon of gas carry-over in the air feeding process and air discharging process of an air compressor is avoided, therefore, the efficiency of the air compressor is improved, and the connecting structure of the cylinder cover and the valve plate component ceiling has the advantages of being simple in structure, reasonable in design and the like.
Description
Technical field
The utility model belongs to cylinder cap and valve board assembly linkage structure technical field, specifically relates to a kind of cylinder cap and valve board assembly ceiling connecting structure.
Background technique
The valve board assembly of air compressor is arranged on the cylinder cap opening, is fixed in the lump the cylinder cover port of cylinder together with cylinder cap, realizes the process of air compressor air intake and exhaust.In prior art,, because the cylinder head diameter is larger, only rely on the rigidity of valve plate in valve board assembly that valve board assembly is sealed in cylinder cap opening intensity not good enough, often make in the process of air compressor air intake and exhaust gas blowby mutually, thereby reduced air compressor efficiency.
Summary of the invention
The utility model is mainly to solve the existing technical problem of above-mentioned prior art, and a kind of cylinder cap and valve board assembly ceiling connecting structure are provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of cylinder cap and valve board assembly ceiling connecting structure, comprise cylinder cap and the valve board assembly that is arranged on cylinder cap lower end mouth place, described cylinder cap center is provided with through hole, be provided with the furred ceiling screw rod in through hole, the center of valve board assembly is provided with tapped hole, and the cooperating structure that is screwed onto on the tapped hole of valve board assembly center via furred ceiling screw rod lower end is connected to the valve board assembly furred ceiling at the lower end mouth place of cylinder cap.
As preferably, also be provided with cylinder cover gasket between the lower end mouth of described cylinder cap and valve board assembly, the cooperating structure that is screwed onto on the tapped hole of valve board assembly center via furred ceiling screw rod lower end is connected to cylinder cover gasket and valve board assembly furred ceiling the lower end mouth place of cylinder cap in the lump.
The utility model improves a little to cylinder cap and valve board assembly linkage structure, set up the structure of using furred ceiling screw rod furred ceiling connection valve board component in the cylinder cap center, after together with cylinder cap, being fixed in the lump the cylinder cover port of cylinder, the intensity of valve board assembly is improved, gas blowby mutually not in the process of air compressor air intake and exhaust, thereby improved air compressor efficiency, therefore the utlity model has the characteristics such as simple in structure, reasonable in design.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1, the utility model is to be provided with through hole 5 in cylinder cap 2 centers, be provided with furred ceiling screw rod 1 in through hole 5, the center of valve board assembly 4 is provided with tapped hole 6, and the cooperating structure that is screwed onto on valve board assembly 4 center tapped holes 6 via furred ceiling screw rod 1 lower end is connected to valve board assembly 4 furred ceilings at the lower end mouth place of cylinder cap 2.Also be provided with cylinder cover gasket 3 between the lower end mouth of cylinder cap 2 and valve board assembly 4, the cooperating structure that is screwed onto on valve board assembly 4 center tapped holes 6 via furred ceiling screw rod 1 lower end is connected to cylinder cover gasket 3 and valve board assembly 4 furred ceilings the lower end mouth place of cylinder cap 2 in the lump.The utility model improves a little to cylinder cap and valve board assembly linkage structure, set up the structure of using furred ceiling screw rod furred ceiling connection valve board component in the cylinder cap center, after together with cylinder cap, being fixed in the lump the cylinder cover port of cylinder, the intensity of valve board assembly is improved, gas blowby mutually not in the process of air compressor air intake and exhaust, thereby improved air compressor efficiency, therefore the utlity model has the characteristics such as simple in structure, reasonable in design.
Finally, should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, and many distortion can also be arranged.Every foundation technical spirit of the present utility model, to any simple modification, equivalent variations and modification that above embodiment does, all should be thought and belong to protection domain of the present utility model.
