Abstract

The invention discloses a hydraulic power mechanism telescopic device. The hydraulic power mechanism telescopic device is characterized by comprising a plunger, oil inlet holes, a cylinder barrel, a guide ring, a shaft seal and a dustproof ring, wherein the cylinder barrel and the plunger are comprised, the cylinder barrel sleeves the plunger, the dustproof ring, the shaft seal and the guide ringare installed between the cylinder barrel and the plunger, and one oil inlet hole is formed in each of the two sides of the cylinder barrel. The hydraulic power mechanism telescopic device has the advantages that the rotation of the plunger in movement can be controlled so that the plunger can be accurately in butt joint with a butt joint object, the structure is simple, the design is reasonable,the production cost is low, and the sealing and dustproof effects are good.

Description

technical field [0001] The invention relates to a hydraulic power device, in particular to a plunger cylinder structure, and in particular provides a hydraulic power mechanism telescopic device. Background technique [0002] At present, the known plunger cylinder is made up of a cylinder barrel, a cylinder bottom, a plunger, a dust seal, a shaft seal, and a guide belt. When the plunger is driven, because there is no lubricating device, its rotation transmission is prone to sudden death, the service life is short, and it is very difficult to connect with the connecting object. Contents of the invention [0003] The object of the present invention is to solve the many technical problems mentioned above, and especially provides a hydraulic power mechanism telescopic device. [0004] The invention provides a hydraulic power mechanism expansion device, characterized in that: the hydraulic power mechanism expansion device includes a plunger (1), an oil inlet hole (2), a cylinde...
