Therefore, in view of the above, research and improvement are made for the existing structure and defects, and a micro hydraulic cylinder structure is provided to achieve a more practical purpose.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a miniature hydraulic cylinder structure to solve current suspension hydraulic pressure lock and sell the after-sale indemnity very high, mainly be the hydraulic pressure oil leak, its reason is mainly because cylinder size design is unreasonable with sealing washer size design, and the processing technology, the product precision of cylinder are unreasonable, the not high problem of practicality.
The utility model discloses purpose and efficiency of miniature hydraulic cylinder structure are reached by following specific technological means:
a micro hydraulic oil cylinder structure comprises a cylinder barrel; a cylinder rod is inserted in the cylinder barrel.
Further, the inside of cylinder is equipped with the seal groove, and the seal groove is equipped with three.
Furthermore, the sealing groove is internally provided with a sealing ring, and the sealing ring is designed into a circular ring body.
Further, the inner diameter of the sealing ring is the same as the outer diameter of the cylinder rod.
Further, the width and the depth of the sealing groove are the same as the outer diameter of the section of the sealing ring.
Compared with the prior art, the utility model discloses following beneficial effect has:
the device is inside to be equipped with three sealing rings, can the effectual phenomenon of solving current hydraulic pressure oil leak, and the seal groove degree of depth is the same with the cross-section external diameter of width and sealing washer to and the internal diameter of sealing washer is the same with the external diameter of jar pole, makes the sealing washer be connected more closely with cylinder and jar pole, can effectively solve the unreasonable oil leak phenomenon that leads to of cylinder size design and sealing washer size design, improves the device's practicality.
