[0002] A door equipped with an anti-theft lock can resist abnormal opening under certain conditions within a certain period of time. It has certain security protection performance and meets the corresponding anti-theft security level. The full name of the anti-theft door is "anti-theft security door", which has both anti-theft and safety performance.

[0003] However, the security door in the prior art actually has certain defects when in use. For example, after being secured by the door lock alarm, it can still be opened through certain technical equipment, so it cannot be completely secured. At the same time, the security door is also installed on the door opening through hinges. Under certain circumstances, the entire security door can be removed with the help of external tools. For this reason, we propose an anti-theft door installation and connection mechanism. Utility Model Content
