Abstract
The utility model relates to the technical field of mechanical energy conversion devices, in particular to a thin cylinder. A piston rod and a piston of the thin cylinder are of a riveted structure, the number of accessories is reduced, the structure of the cylinder is optimized, a rear end cover and the rear end of the cylinder are of a riveted structure, the number of the accessories is much fewer, the yield is higher, and moreover the concentricity is improved. The thin cylinder comprises a cylinder body, wherein a front end cover is arranged at the front end of the cylinder body, the rear end cover is arranged at the rear end of the cylinder body, the piston and the piston rod are arranged in the cylinder body, one end of the piston rod is connected with the piston, the other end of the piston rod penetrates through the front end cover and then is located outside the cylinder body, the piston rod is in riveted connection with the piston, and the rear end cover is in riveted connection with the rear end of the cylinder body.
Description
Technical field
The utility model relates to the technical field of mechanical energy conversion device, particularly relates to a kind of thin cylinder.
Background technique
As everyone knows, cylinder is a kind of cylindrical metal parts that guide piston to carry out therein straight reciprocating motion, and its work is to be mainly mechanical energy by thermal power transfer, and thin cylinder is a kind of in cylinder, is widely used in every field; Existing thin cylinder finds in using, and it mostly exists structure old, and such as being connected of piston rod and piston, rear end cover mostly adopts thread helix to connect with rear end of the cylinder block, not only will increase accessory concentricity and facilitate and can not effectively be guaranteed.
Model utility content
For solving the problems of the technologies described above, the utility model provides a kind of piston rod and piston to adopt riveted construction, the accessory of minimizing, optimized air cylinder structure, and rear end cover and rear end of the cylinder block employing riveted construction, accessory is still less, up-to-standard rate is higher, and has improved a kind of thin cylinder of concentricity.
A kind of thin cylinder of the present utility model, comprise cylinder body, the front end of described cylinder body is provided with front cover, the rear end of described cylinder body is provided with rear end cover, in described cylinder body, be provided with piston and piston rod, one end of described piston rod is connected with piston, and the other end of described piston rod is through the outside that is positioned at described cylinder body after front cover, described piston rod and piston riveted link together, and the rear end riveted of described rear end cover and described cylinder body links together.
A kind of thin cylinder of the present utility model, also comprises two O type piston packings, and described pair of O type piston packing is arranged on the outer side surface of described piston.
A kind of thin cylinder of the present utility model, also comprises O type circle, and described O type circle is arranged on the outer side surface of described front cover.
A kind of thin cylinder of the present utility model, also comprises dust-proof seal ring, and described dust-proof seal ring is arranged on the inner side of described front cover.
A kind of thin cylinder of the present utility model, also comprises circlip, and described circlip is arranged on the installation place of described front cover and cylinder body.
Compared with prior art the beneficial effects of the utility model are: by above-mentioned setting, can adopt riveted construction by piston rod and piston, the accessory reducing, optimized air cylinder structure, and rear end cover and rear end of the cylinder block adopt riveted construction, still less, up-to-standard rate is higher for accessory, and has improved concentricity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of thin cylinder of the present utility model, comprise cylinder body 1, the front end of cylinder body is provided with front cover 2, and the rear end of cylinder body is provided with rear end cover 3, is provided with piston 4 and piston rod 5 in cylinder body, one end of piston rod is connected with piston, the other end of piston rod is through the outside that is positioned at cylinder body after front cover, and piston rod and piston riveted link together, and the rear end riveted of rear end cover and cylinder body links together; By above-mentioned setting, can adopt riveted construction by piston rod and piston, the accessory of minimizing, has optimized air cylinder structure, and rear end cover and rear end of the cylinder block employing riveted construction, and still less, up-to-standard rate is higher for accessory, and has improved concentricity.
