, Lock configuration
A mechanical explosion-proof key lock, a mechanical combination lock imported from the United States, and a gong-plated glove. (Other factories only provide ordinary anti-theft locks, which do not meet explosion-proof requirements.) The round hand wheel controls the lock point switch around the door frame, which is permanently rust-free, beautiful and practical. It is also equipped with a mechanical combination lock imported from the United States, which has passed international certification.
, Lock point
There are no less than two solid lock tongues on both sides of the door leaf. After the door is closed, the lock tongue and the door frame are tightly coupled with each other to form a closed body, which is more difficult to blast. Even if the door is damaged, the door body will not break away from the door frame. There is a dragon-electric linkage mechanism inside, which has the functions of arc prevention, prying prevention, and fire prevention.
