Problems solved by technology
[0004] The cam of the electromagnetic door lock of the present invention can lock the door hook when it rotates to lock the door lock. At the same time, the cam can also move upwards to tighten the door hook, which can overcome the difference in the thickness of the gasket or the elastic performance. The inconsistency of the length and other factors that affect the change of the door lock cause the problem of poor sealing

An electromagnetic door lock: comprising a door lock box, the door lock box has a bottom, the door lock box is provided with a mounting bracket, the mounting bracket can move up and down or reciprocating relative to the bottom of the door lock box, the mounting bracket Two ends are oppositely arranged along its length direction, and installation grooves are oppositely arranged on the two ends; cam shafts are extended from both sides of the cams, and the cam shafts are installed on the two ends of the installation brackets respectively. In the installation groove, the middle part of the cam is provided with a door lock hook for receiving the door hook, and the upper part of the cam is provided with a step. The cam of the electromagnetic door lock of the present invention can lock the door hook and lock the door lock when it rotates, and at the same time, the cam can also move upwards to tighten the door hook, so as to overcome the difference in gasket thickness or elastic performance and affect the door lock. The problem of lax sealing caused by other factors of change.
Description
technical field [0001] The invention relates to a door lock for commercial or household electrical appliances, in particular to an electromagnetic door lock with washer compensation function. Background technique [0002] The normal use of electrical equipment has certain requirements on the door lock mechanism of the equipment. The doors of commercial or household electrical equipment such as washing machines, dishwashers, etc. need to be completely sealed and closed for normal operation. Generally, a gasket is added to the door to enhance the sealing performance. However, the gasket is generally made of rubber or plastic. Different manufacturers have different production processes, different material elastic properties, different thermal expansion ranges, different aging degrees, and different factors that affect the change of the door hook, such as the length of the door hook. All lead to the sealing performance of the gasket. The difference will affect the sealing perf...
