Description of the embodiments

Fig. 1 to 3 show a concrete implementation of a burglary-resisting door lock bolt clearance compensation device of the utility model, it includes burglary-resisting door frame 1, burglary-resisting door leaf 2, double-fast lock body 3, burglary-resisting door leaf 2 is hinged on burglary-resisting door frame 1 through hinge 5 and has handles 9, double-fast lock body 3 is installed on burglary-resisting door leaf 2, the corresponding lock body 3 has lock bolt 7 and lock core 8, install the bolt box 4 cooperating with lock bolt 7 on burglary-resisting door frame 1 corresponding to double-fast lock body 3, the key drives the lock bolt 7 to work through the mechanical structure of lock core 8 and double-fast lock body 3, there are lock bolt clearance compensation mechanisms 6 on the said lock bolt box 4, the said lock bolt clearance compensation mechanism 6 includes the slide block 15, spring 11, there are inclined planes or cambered surfaces 10 cooperating with lock bolt 7 on the slide block 15 and can be set up on the lock bolt box 4 horizontally, the spring 11 is set up between slide block 15 and lock bolt box 4, the elasticity of spring 11 is greater than the rotational resistance of the burglary-resisting door; in the closing process of the anti-theft door, the lock tongue 7 is in sliding contact with the inclined surface or the cambered surface 10 of the sliding block 15, and the sliding block 15 pushes the lock tongue 7 to drive the anti-theft door leaf 2 to rotate under the elastic force of the spring 11 to eliminate a lock tongue gap, so that the outer surface of the anti-theft door leaf 2 is kept level with the outer surface of the anti-theft door frame 1.

In order to ensure smooth, stable and reliable sliding of the sliding block 15, the lock tongue box 4 is provided with a guide chute 13, the sliding block 15 is provided with a limit guide piece 14, and the limit guide piece 14 is arranged on the guide chute 13 in a sliding way. The inclined plane or the cambered surface 10 of the sliding block 15 is positioned at the outer side of the lock tongue 7 at one side close to the double-quick lock body 3 when the anti-theft door is in an open state, so that the lock tongue 7 is reliably matched with the sliding block 15 when the anti-theft door is closed.

In order to facilitate the positioning of the spring 11, the spring bolt box 4 is fixed with a spring positioning pin 12, and the spring 11 is correspondingly arranged on the spring positioning pin 12.

When the lock tongue 7 of the anti-theft door starts to be closed, the lock tongue 7 is in sliding contact with the inclined surface or the cambered surface 10 of the sliding block 15, when the elastic force of the spring 11 is larger than the rotation resistance of the anti-theft door, the sliding block 15 pushes the lock tongue 7 to drive the anti-theft door leaf 2 to rotate under the elastic force of the spring 11 to eliminate a lock tongue gap, so that the outer surface of the anti-theft door leaf 2 is kept flush with the outer surface of the anti-theft door frame 1, and the compensation function of the lock tongue gap is realized; when the elastic force of the spring 11 is smaller than the rotation resistance of the anti-theft door, the lock tongue 7 of the anti-theft door continues to slide along the inclined surface or the cambered surface 10 of the sliding block 15, the anti-theft door leaf 2 stops rotating, the lock tongue 7 pushes the lock tongue box 4 to retract until the lock tongue 7 is completely locked against the elastic force of the spring 11, and therefore the sealing reliability and the sealing effect of the anti-theft door are ensured, as shown in fig. 1 and 2.

In the utility model, when the anti-theft door is opened, as shown in figure 3, the sliding block 15 automatically resets to the initial state under the action of the elasticity of the spring 11.

The foregoing is merely one embodiment of the present utility model and is not intended to limit the utility model in any way, and simple modifications, equivalent variations or modifications can be made without departing from the technical solution of the present utility model, all falling within the scope of the utility model.
