Example Embodiment

[0014] The present invention will be further explained below in conjunction with the drawings:

[0015] Such as figure 1 As shown in -4, a damper with good sealing performance includes a cylindrical shell 1, which is provided with a sealing assembly 2, a piston assembly 3, and a driving assembly 4 that drives the piston assembly 3 up and down. The sealing assembly 2 includes an end cover 21 and a sealing sleeve 22 sleeved outside the end cover 21. The upper part 211 of the end cover 21 is in the shape of an annular disc and the outer edge of the upper part 211 of the end cover is surrounded by an annular protrusion 011, The upper end surface of the upper part 211 of the end cap is provided with a vent hole 012, the middle part 212 of the end cap 21 is a circular tube, the lower part 213 of the end cap 21 is an annular cover, and the middle parts 212 of the end cap 21 are respectively Connected with the upper part 211 of the end cap 21 and the lower part 213 of the end cap 21, the...

Abstract

The invention provides a damper with good sealing performance. By means of the flange riveting arrangement of the opening end of a shell, an end cover and a sealing ring are riveted tightly in the shell, damping oil is completely sealed in the shell, a ring baffle on the lower portion of a sealing sleeve blocks damping oil adhering to the outer wall of a piston core shaft, the damping oil is prevented from being taken out of the shell by the piston core shaft, gas enters a gas temporary storage space in the sealing sleeve from a vent hole in the upper end face of the end cover, the barometricpressure is increased to the sealing sleeve, the sealing sleeve achieves better sealing, and the damping oil cannot leak outwards.

Description

technical field [0001] The invention relates to a damper with good sealing performance. Background technique [0002] The main function of the damper is to relatively generate frictional force or viscous force against the motion when the motion system is in motion, so as to slow down the trend of the object, so that the motion decreases with time, and eventually approaches zero. Therefore, the damper has good shock absorbing and buffering functions, and is widely used in the industrial field. Currently commonly used dampers on the market, because of poor sealing performance, the damping oil in the damper is easily splashed, or leaks naturally due to temperature changes. After long-term use, the splashed damping oil dries up, not only causing seat The periphery of the body is fouled, and because the total amount of damping oil stored in the damper is gradually reduced, the shock absorbing and buffering effect is gradually lost. Contents of the invention [0003] In order ...
