CN201507640U - An all-inclusive piston - Google Patents

Abstract

The utility model discloses a fully covered piston which comprises a piston body. At least a chute is arranged on the lateral surface of the piston body. The utility model has the advantages that a piston ring is fixed through arranging the chute on the lateral surface of the piston body; and the piston has reasonable structure; good stability and strong sealing performance. The external dimension of the fully covered piston with the structure is easy to control; the piston ring and the piston body are more stably and firmly fixed and matched so as to be convenient for massive production and operation; and the fully covered piston is mature and reliable technically.

Description

An all-inclusive piston

technical field

The utility model relates to a piston, more specifically, it relates to an all-inclusive piston.

Background technique

At present, the piston of the prior art generally has a piston ring groove, and the piston ring is placed in the piston ring groove. When the piston works in the shock absorber, the piston ring will produce elastic deformation, and there will be a part of excessive deformation, which will easily cause the piston and piston The ring fit is not tight, which reduces the sealing performance of the piston. Moreover, this structure mainly limits the position of the piston ring through the groove edge of the piston ring groove, which easily causes the piston ring to slip and affects the stability of the sealing performance.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide an all-inclusive piston with reasonable structure, good stability and strong sealing.

The purpose of this utility model is achieved through the following technical solutions. The all-inclusive piston includes a piston body, and at least one circle of grooves is provided on the side of the piston body.

The grooves are uniformly distributed on the side of the piston body in a zigzag shape.

The piston ring is wrapped and fixed on the side of the piston body, and the piston ring matches the groove.

The beneficial effect of the utility model is that the fixing of the piston ring is realized by providing grooves on the side of the piston body, and the utility model has reasonable structure, good stability and strong sealing performance. The all-inclusive piston with this structure is easy to control the external dimensions, and the fixing and fitting of the piston ring and the piston body are relatively firm and stable, which is convenient for mass production and operation, and is also very mature and reliable in technology.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further. Although the utility model will be described in conjunction with preferred embodiments, it should be understood that it does not mean that the utility model is limited to the embodiments. On the contrary, the invention is to cover alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims.

Referring to Fig. 1-2, the all-inclusive piston introduced here is generally used in a shock absorber, but it should be known that the utility model can also be used in other piston assembly structures except shock absorbers. The all-inclusive piston includes a piston body 1, and at least one ring of grooves 2 is provided on the side of the piston body 1. The grooves 2 are evenly distributed on the side of the piston body 1 in a zigzag shape. The piston ring 3 is wrapped and fixed on the side of the piston body 1, and the piston ring 3 matches the groove 2.

There are serrated grooves 2 on the side of the all-inclusive piston, and the piston ring 3 is wrapped and fixed on the side of the piston body 1 . The fixing of the piston ring 3 is achieved by means of the serrated groove 2 . The entire piston is the all-inclusive piston that already includes the piston ring 3 . The all-inclusive piston of this structure is easy to control the external dimensions, and the fixation and fit between the piston ring 3 and the piston body 1 are relatively firm and stable, which is convenient for mass production and operation, and is also very mature and reliable in technology.
