Description

Technical Field

[0001] The utility model relates to the technical field of lock buckles, in particular to a novel lock buckle. Background Art

[0002] Smart door and window locks include a lock box and a lock catch. The lock box is installed on the door body, and the lock catch is installed on the door frame. When locking the door, the door body and door frame can be locked by the lock pin and the bayonet pin. Figure 1 As shown, the patent with application number CN202021265652.5 discloses a lock, whose lock plate 20 is enclosed by a front cover 21 and a rear cover 22, and a lock pin 23 is arranged in the front cover 21 and passes through an opening of the rear cover 22 for cooperating with the latch of the lock box.

[0003] However, the rear cover 22 and the front cover 21 of the above patent are connected by a threaded connection. When a large external force is used to pull the door body in an unlocked state, the locking pin of the lock box on the door body drives the locking pin 23, and the locking pin 23 pulls the rear cover 22, making it easy for the locking pin 23 and the rear cover 22 to fall off from the front cover 21, and the safety is relatively low.
