Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel door anti-theft, in particular to an anti-theft structure for stainless steel doors. Background Art

[0002] Stainless steel doors are made of stainless steel plates by shearing and pressing. They look the same as ordinary doors. When thieves steal, they usually open the door lock and then steal. Now, they usually install an anti-theft chain and anti-theft structure to provide double protection with the lock.

[0003] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the existing anti-theft structure for stainless steel doors relies on the positioning of the clamping head and the clamping block to limit one end of the chain and then limit the stainless steel door, but the thief can use a pole to lift the anti-theft chain and disassemble the clamping head part. The safety factor of the existing structure is not ideal and needs to be improved urgently. Therefore, we propose an anti-theft structure for stainless steel doors. Utility Model Content
