Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lock boxes, in particular to a novel lock box. 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 lock pin of the lock catch and the lock box's bayonet pin cooperate to lock the door body and door frame. Figure 1 As shown, the patent with application number CN2020212691571 discloses a lock box and a lock buckle used in conjunction with the lock box. When locking the door, when the lock pin of the lock buckle is inserted into the mortise 140 of the lock buckle box 14, the motor 12 drives the worm rod 122 to rotate, thereby driving the gear component 123 to rotate, so as to drive the tooth plate 124 to move to drive the bayonet 126 to insert into the slot of the lock pin of the lock buckle, thereby locking the door; when unlocking, the motor 12 drives the worm rod 122 to rotate in the opposite direction, thereby driving the gear component 123 to rotate in the opposite direction, so as to drive the tooth plate 124 to move in the opposite direction to drive the bayonet 126 to be pulled out from the slot of the lock pin of the lock buckle, and unlocking can be achieved at this time.
[0003] However, in the above patent, in order to keep the lock box and the lock buckle working properly, the gear component 123 and the tooth plate 124 need to be kept engaged at all times. If the rotation angle of the motor 121 is too large, the gear component 123 and the tooth plate 124 will easily disengage, and the door locking and unlocking actions cannot be performed. The device needs to be repaired or scrapped and replaced, which greatly increases the operation and maintenance costs. Utility Model Content
