AI Technical Summary

Problems solved by technology

Similar household power distribution box locks and drawer cabinet locks require too much space, which greatly affects the overall structural design of the air-opening protective cover behind the secondary screen cabinet. The current situation urgently needs a special lock for the protective cover. Provides latching function

First, the lock body of the commonly used cabinet door lock is more than 3cm square, which is too large to meet the space design and installation of the secondary screen cabinet protection cover.

Second, the lock body of the existing rotary cabinet lock is round, and it is only clamped by the nut, which is easy to slip

Third, the structure of the existing lock body is complicated, and it is tightly sealed when leaving the factory. When one of the parts wears out, it must be replaced as a whole, resulting in waste

Fourth, the existing lock is an integrated lock cylinder and locking part. When the lock cylinder is stuck or the key is lost, the entire lock and even the entire protective cover must be destroyed to open the protective cover, which increases the risk of electrical equipment.
