Description

Technical Field

[0001] This utility model relates to the field of door locks, and in particular to a door lock that can be installed in either direction. Background Technology

[0002] In existing technologies, mechanical door locks are often upgraded with intelligent features, combining the advantages of both mechanical and smart door locks. For example, Chinese Utility Model Patent 2025212145857 discloses a door lock that can be installed without modifying the holes on the door body. However, this type of door lock uses rotating slots, threading slots, and pull slots on the base. Since the threading slots are eccentrically positioned on the base, although the problem of needing to modify the holes is solved, it also leads to the need to distinguish between upright and reverse installation. Not only do manufacturers need to keep inventory of both upright and reverse door locks, but users also need to carefully distinguish them when purchasing, which still has certain drawbacks. Therefore, there is an urgent need for a door lock that can be installed in both upright and reverse configurations to solve the above problems. Utility Model Content
