Abstract
The utility model provides an axially-sealed oil cylinder preventing oil leakage. The axially-sealed oil cylinder comprises a cylinder body and a piston assembled inside the cylinder body, wherein the side wall in the cylinder body is provided with a sealing groove; the sealing groove is internally provided with an axial sealing ring; and the axial sealing ring is tightly sleeved on the piston. Since the axial sealing ring is adopted, though the requirement for the piston is improved, the requirement of the inner hole of the cylinder body on glossiness and rigidity can be met just by simple heat treatment and excircle grinding processing, therefore the processing cost of parts is saved, the sealing ring can not be worn easily, the service life of the sealing ring is prolonged greatly and the safety of products is enhanced.
Description
Technical field
The utility model relates to the oil cylinder technical field, refers in particular to a kind of axial seal oil cylinder of anti-leakage of oil.
Background technique
The seal ring that existing oil cylinder adopts all is that seal ring use in the hole mostly, in the oil cylinder working procedure, because piston constantly motion in cylinder body, is positioned at seal ring on the piston in a single day by plucking, oil leakage phenomenon will occur, required braking force in the time of also just can't reaching work.And the hole is all very high to degree of finish, the hardness requirement of cylinder inner bore with seal ring, and difficulty is all compared in the processing of cylinder inner bore and heat treatment, is difficult to reach requirement, and seal ring also is easy to wearing and tearing simultaneously, oil leakage phenomenon often occurs.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of existing technology, and the oil cylinder of a kind of good airproof performance, oil-proof, long service life is provided.
For realizing above-mentioned purpose; The technological scheme that the utility model provided is: a kind of axial seal oil cylinder of anti-leakage of oil, and it includes cylinder body and the piston that is assemblied in the cylinder body, and the cylinder body madial wall is provided with seal groove; Be provided with axial sealing ring in the seal groove, axial sealing ring closely is linked on the piston.
Described seal groove is two, lays respectively at the oil leab both sides of cylinder body.
The axial sealing ring that the utility model adopts is though concerning piston, improved requirement; But degree of finish and hardness to cylinder inner bore requires just can satisfy through the grinding of simple heat treatment and cylindrical; Thus, not only practiced thrift the processing cost of part, seal ring is not easy to wear yet simultaneously; Prolong the working life of seal ring greatly, improved security of products.
Description of drawings
Fig. 1 is the overall structure schematic representation of the utility model.
Embodiment
Below in conjunction with institute's drawings attached the utility model is described further; The preferred embodiment of the utility model is: referring to accompanying drawing 1, the axial seal oil cylinder of the described anti-leakage of oil of present embodiment includes cylinder body 1 and the piston 2 that is assemblied in the cylinder body 1, and cylinder body 1 madial wall is provided with seal groove 4; Seal groove 4 is two; Lay respectively at oil leab 5 both sides of cylinder body 1, be provided with axial sealing ring 3 in the seal groove 4, axial sealing ring 3 closely is linked on the piston 2.The axial sealing ring 3 that this structure adopts is though concerning piston, improved requirement; But degree of finish and hardness to cylinder inner bore requires just can satisfy through the grinding of simple heat treatment and cylindrical; Thus, not only practiced thrift the processing cost of part, seal ring 3 is not easy to wear yet simultaneously; Prolong the working life of seal ring 3 greatly, improved security of products.
The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.
