Household appliance switch bracket with self-locking device

Abstract

A household appliance switch bracket with a self-locking device comprises a switch bracket body, a door hook support, a microswitch and a door hook. The door hook is located on a door body. The household appliance switch bracket is characterized in that a rotary joint, the door hook and a slide bar are arranged on the switch bracket body, the rotary joint is provided with a spring bolt and a self-locking hole, the door hook is provided with a clamping hole, the slide bar is provided with a guide pillar, the rotary joint is clamped to the clamping hole and the guide pillar through the spring bolt and the self-locking hole respectively, and then self-locking structures of the appliance switch bracket are formed. According to the household appliance switch bracket with the self-locking device, the door hook and the rotary joint form one self-locking structure, the slide bar and the rotary joint form the other self-locking structure, the two different self-locking structures enable the household appliance switch bracket to be self-locked more stably, and efficient self-locking of the household appliance switch bracket is realized; the door hook support makes contact with the rotary joint and the slide bar, so that self-locking of the household appliance switch bracket is relieved; meanwhile, the household appliance switch bracket is of a mechanical structure, is high in reliability and has the advantages of being simple and reasonable in structure, quick and convenient to operate, long in service life, high in stability and the like.

Description

technical field [0001] The invention relates to a home appliance switch bracket with a self-locking device, which belongs to the technical field of home appliances. Background technique [0002] Common switch bracket components include: switch bracket, swivel joint, door hook support, micro switch and door structure. The door hook is located on the door body. On the front side, left side / right side of the frame, there are micro switches on the switch bracket; by pressing down on the door hook to touch the rotary joint, the rotary joint rotates, touches the micro switch to close, and the deadbolt buckles in the door hook hole. It can work normally; when the door is opened, the door hook support is forced to rotate to drive the rotary joint, so that the rotary joint lock tongue is disengaged from the door hook hole, the door hook opens with the door body, the rotary joint continues to rotate under the action of the spring, and the micro switch contacts Disconnect immediately....

AI Technical Summary

Problems solved by technology

This traditional switch bracket assembly cannot form a self-lock when the door is closed, and it is easy to rotate the rotary joint when it is subjected to external vibrations and abnormal movements, so that the door can be easily opened, affecting the normal use of electrical appliances

Because of instability, it will greatly affect the service life of electrical appliances and affect the cooking of ingredients
