Damping adjustment rotating shaft mechanism for washing machine cover plate

Abstract

The invention discloses a damping adjusting and shaft rotating mechanism that can be used in cover boards of washing machines and comprises a shaft sleeve, a fin board is respectively arranged at the left and right sides of an inner wall of the shaft sleeve and has flow impelling action, a rotating shaft is arranged inside the shaft sleeve, a wing plate with a middle opening is respectively arranged at the left and right sides of the rotating shaft, and a spring leaf is respectively spliced in the opening of each wing plate; gaps between the rotating shaft and the shaft sleeve are filled with damping liquid or damping paste, a sealing gland bush is arranged between the rotating shaft and an end part of the shaft sleeve so as to prevent the damping liquid or the damping paste from leaking out, the fin boards and the wing plates are interlaced, and the rotating shaft can rotate inside the shaft sleeve. The damping adjusting and shaft rotating mechanism of the invention leads integral cover boards of the washing machines to have constant speed in the closing process, overcomes the phenomenon that the cover board has fierce impact on a face frame due to self weight in the rotating and declining process, and leads the cover board to slowly decline and lightly fall over the face frame.

Description

technical field [0001] The invention belongs to a rotating shaft mechanism, in particular to a damping adjusting rotating shaft mechanism that can be used for the cover plate of a washing machine or the cover plate of other household appliances. Background technique [0002] Most of the existing washing machine cover plates are foldable, so as to avoid impact with the noodle frame. Although this method can better overcome the impact with the surface frame, the division of the cover plate into two parts not only affects the appearance, but also causes difficulties in the cooperation between the cover plates and the cooperation between the cover plate components and the surface frame, and the mechanical strength It is also poor, and often the strength of the cover assembly can only be increased by increasing the thickness to meet the requirements of the impact test. If the integral cover plate is used, it is not only inconvenient to use the traditional gripper to open and clo...

Problems solved by technology

Although this method can better overcome the impact with the surface frame, the division of the cover plate into two parts not only affects the appearance, but also causes difficulty in the cooperation between the cover plates and the cooperation between the cover plate components and the surface frame. It is also poor, and often the strength of the cover assembly can only be increased by increasing the thickness to meet the requirements of the impact test

If the integral cover plate is used, it is not only inconvenient to use the traditional gripper method to open and close the cover plate, but also the cover plate is very easy to get out of the hand, causing it to impact with the surface frame and make a large impact noise, especially in large capacity washing machine
