Shock absorber and clothing treatment equipment

Abstract

The invention belongs to the technical field of damping shock absorbing devices, and particularly relates to a shock absorber and clothing treatment equipment. The shock absorber and the clothing treatment equipment aim to solve the problem of inconvenient assembly of existing large damping shock absorbers. For the purpose, the shock absorber comprises a sleeve, a plunger and a damping ring, the plunger is slidably inserted into the sleeve in the axial direction, and the damping ring is arranged radially between the plunger and the sleeve. External threads are arranged on the outer circumferential surface of the plunger, internal threads are arranged on the inner circumferential surface of the damping ring, the plunger and the damping ring are engaged together through the external threadsand the internal threads, and the outer circumferential surface of the damping ring abuts against the inner wall of the sleeve. Under the action of the internal threads and the external threads, the damping ring can perform axial and rotating motion with the movement of the plunger, the axial damping force and rotating damping force are generated, and the damping force is increased without increasing the diameter of the damping ring to avoid the situation of difficult assembly of the shock absorber.

Description

technical field [0001] The invention belongs to the technical field of damping and shock absorbing devices, and specifically provides a shock absorber and clothes processing equipment. Background technique [0002] The existing drum washing machine mainly includes a casing, an outer cylinder and an inner cylinder. Wherein, the outer cylinder is fixedly connected with the box body through a hanging spring and a shock absorber. Specifically, the top of the outer cylinder is fixedly connected to the top of the box body through a hanging spring, and the bottom of the outer cylinder is fixedly connected to the bottom of the box body through a shock absorber. The inner cylinder is rotatably arranged in the outer cylinder. [0003] During the working process of the washing machine, due to the uneven distribution of clothes in the inner cylinder, the inner cylinder will drive the outer cylinder to shake up and down, left and right when rotating. The setting of the hanging spring ...
