Description

technical field [0001] The invention relates to the field of door locks, in particular to a safety door latch structure that can be widely used in various safes, safes and anti-theft doors and has good reliability and safety in use. Background technique [0002] Along with the raising of people's living standard, various safe doors have been more and more applied in people's daily life, such as various safes, safes and household anti-theft doors etc. Existing safety doors, in terms of their structure, mainly include a door frame, a door body pivotally connected to the door frame, and a door latch structure arranged between the door body and the door frame. The traditional latch structure is generally a single horizontal latch structure, which includes a lock plate arranged on the back of the door body and a horizontal latch interlocked with the lock plate, and a latch hole matching the latch is opened on the door frame. In addition, mechanical locks and / or electronic locks ...

AI Technical Summary

Problems solved by technology

However, these structures are relatively complicated, and the protection of the four corners of the door body has been ignored.

In fact, the corners of the door body are the weakest link on the door body. After being hit or pried, they are easily warped and deformed, resulting in the destruction of the entire door body, which makes the latch structure lose its due protection effect, especially Corners on the non-pivoting side are more likely to be damaged

This shows that the safety of existing safety door latch still needs to be further improved
