Abstract

The invention discloses a hydraulic device with a buffer function, which comprises a conical inner column with a closed front end and a casing sleeved outside the inner column. The air hole; the middle part of the outer wall of the inner column is provided with an annular groove, the lower end of the inner column is provided with a plurality of chutes in the circumferential direction, the upper end of the inner column is provided with a bent oil groove, and the inner wall of the shell is provided with an annular groove. Grooves, chutes and oil passages. When the invention is installed, the taper is easier to compress and the sealing effect is better; when the hydraulic oil passes through the oil passage groove and the screw hole inside the oil passage column, the passage speed can be greatly reduced and a good buffering effect can be achieved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic cylinders, and in particular relates to a hydraulic device with a buffer function. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It has simple structure and reliable operation. The hydraulic device is used to support the heavy object. When the heavy object needs to be lowered, hydraulic oil is still needed to support and release it slowly, so as to prevent the heavy impact from being damaged or damage the hydraulic system. Therefore, there is an urgent need for a solution A hydraulic cylinder with a buffer function for the above problems. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, the present invention provides a hydraulic device with a buffer function, which can realize a hydraulic device with buffer ...
