Embodiment

[0023] as attached figure 1 to attach image 3 Shown:

[0024] The invention provides a micro hydraulic cylinder structure, which includes a cylinder barrel 1; a cylinder rod 2 is plugged inside the cylinder barrel 1.

[0025] Wherein, the inside of cylinder 1 is provided with sealing groove 101, and sealing groove 101 is provided with three, as attached figure 2 And attached image 3 As shown, the multi-channel sealing groove 101 and the sealing ring 102 can effectively prevent oil leakage during the operation of the device and improve the stability of the device.

[0026] Wherein, a sealing ring 102 is arranged inside the sealing groove 101, and the sealing ring 102 is designed as a circular ring body, as attached figure 2 And attached image 3 As shown, this design enables the sealing ring 102 to surround the outside of the cylinder rod 2 .

[0027] Wherein, the inner diameter of the sealing ring 102 is the same as the outer diameter of the cylinder rod 2, as attach...

Abstract

The invention discloses a micro hydraulic cylinder structure, relates to the technical field of hydraulic cylinders, and solves the problem of hydraulic oil leakage caused by unreasonable cylinder barrel size design and seal ring size design of an existing suspension hydraulic lock. The micro hydraulic cylinder structure comprises a cylinder barrel; and a cylinder rod is inserted into the cylinderbarrel. According to the micro hydraulic cylinder structure provided by the invention, three seal rings are arranged inside the device, thus the existing hydraulic oil leakage phenomenon can be effectively solved; the depth and width of a sealing groove and the outer diameter of the cross sections of the seal rings are the same, and the inner diameter of the seal rings is the same as the outer diameter of the cylinder rod, so that the seal rings are more closely connected with the cylinder barrel and the cylinder rod, the oil leakage phenomenon caused by the unreasonable cylinder barrel sizedesign and the seal ring size design can be effectively solved, and the practicability of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic cylinders, and more specifically relates to a micro hydraulic cylinder structure. Background technique [0002] Hydraulic transmission uses liquid as the working medium, and uses the pressure of the liquid to transmit power. At present, the suspension hydraulic lock is a commonly used lock bolt for automobiles. [0003] The after-sales compensation rate of the existing suspension hydraulic lock is very high, mainly due to hydraulic oil leakage. The main reason is that the size design of the cylinder barrel and the size design of the sealing ring are unreasonable, the processing technology and product accuracy of the cylinder barrel are unreasonable, and the practicability is not high. . [0004] Therefore, in view of this, researches and improvements are made on the existing structure and defects, and a micro hydraulic cylinder structure is provided in order to achieve a more practical purpose....
