Problems solved by technology

[0002] Locks are closely related to people's lives. Quite a few people have multiple contacts with locks in a day. It takes a certain amount of time to open and close door locks, because most of the existing anti-theft door locks are cumbersome to use: the main bolt When opening and closing the door, the key needs to be rotated repeatedly. In order to save trouble, people often do not use the main bolt to lock the door, so that the anti-theft door cannot play its due role, which greatly increases the safety hazard.

For this reason, people have invented the novel anti-theft door lock that can quickly lock and open again, and as the patent publication number is CN1594806A, the anti-theft door lock that application number is 200410025796. It can quickly lock and quickly open the anti-theft door lock, but this anti-theft door lock also has some major problems in many aspects of function setting and structural arrangement: by using the handle to quickly open the anti-theft door lock, the outer handle that is extremely easy to damage can be destroyed. Finally, the main bolt can be opened by drilling through the shaft hole, which has a huge potential safety hazard; it is easy to accidentally lock the main bolt with an external handle outdoors, which adds extra trouble; a key is needed to finally lock the security door absolutely. Still not convenient enough; when you have to use a key to open the anti-theft door lock, you have to turn the key repeatedly to open it, which is troublesome; when using the windproof tongue, it often involves the movement of many irrelevant parts, which is easy to damage, and the use of the safety tongue is also very unreasonable.
