Problems solved by technology

[0006] Therefore, the technical problem to be solved by the present invention is that when the existing door lock structure is in the open state, the cam can drive the toggle piece to turn on the switch when it is pried by other objects, and control the power supply of the electrical equipment to turn on and work, causing the door to open. The safety of the lock structure is low, which is easy to cause safety accidents

Abstract

The invention discloses a door lock. The door lock includes a cam rotatably arranged on a lock base, a door hook, a first elastic piece and at least two limiting assemblies. A protrusive pulling partis arranged on the cam, the door hook stretches into a through hole and drives the cam to clockwise rotate in order to drive the pulling part to abut against a door lock structure under a locking state or retracts from the through hole in order to remove the limitation of the cam under an unlocking state; the limiting assemblies are retractably arranged at the through hole in the lock base and apply an abutting force for limiting the clockwise rotation of the cam under the unlocking state. According to the door lock structure, when the door hook stretches into the through hole before switchingof the locking state, all the limiting assemblies slide to remove the abutting force performed on the cam under the action of a pulling force of the door lock at the same time. When a screwdriver andother sharp objects are inserted into the through hole, the cam can be unlocked from only one limiting assembly but is still abutted against by the other limiting assemblies and cannot clockwise turnover to switch to the locking state.

Description

technical field [0001] The invention belongs to the technical field of electrical door locks, and in particular relates to a door lock structure and electrical equipment. Background technique [0002] The electrical equipment in the prior art usually includes an electrical main body, a door panel, a door lock, a door hook, a locking device and a control switch.
