Abstract

The present invention discloses an improved door lock, comprising a lock body, a lock core matched with the lock body, an outer panel and an inner panel, wherein the back of the outer panel is provided with screw holes matched with mounting screws on the front door panel of the sandwich door leaf. In the present invention, since the outer panel is directly fixed on the front door panel of the sandwich door leaf, even if the door leaf is impacted by an external force and the front door panel is deformed, the outer panel is always tightly combined with the front door panel, and a gap will not be formed between the outer panel and the front door panel due to the deformation of the front door panel. It is difficult to pry off the outer panel with a tool, and the lock core can be protected. The above structure of the present invention greatly improves the anti-theft performance of the anti-theft door.

Description

A kind of improved door lock and adopt the door leaf structure of this lock

Technical field

The invention belongs to lockset, be specifically related to a kind of improved door lock and adopt the door leaf structure of this lock.

Background technology

Existing door lock comprises lock body 7, the lock core 5 that cooperates with lock body 7, outer panels 1 and wainscot 2 as shown in Figure 1 and Figure 2.When door lock was installed, the screw at outer panels 1 back side was taken over the front door 8 of 4 insertion door leafs 3, with screw 6 outer panels 1 and wainscot 2 correspondences was installed on the forward and backward door-

plate

8,9 of door leaf 3, and this class formation can not prevent that violence destroys.Most door leaf 3 all is an interlayer; door leaf 3 is subjected to easy deformation behind the external force collision; as shown in Figure 3; make to form gap 11 between the front door 8 of outer panels 1 and door leaf 3, be easy to outer panels 1 be prized, thereby lock core 5 is exposed to outside the door leaf 3 with picklock; because core 5 has not had outer panels 1 protection; be easy to instrument core 5 be twisted off, easily door opened the purpose that reaches the crime of entering the room then, there is great potential safety hazard in such package assembly.

Summary of the invention

The purpose of this invention is to provide a kind of improved door lock and adopt the door leaf structure of this lock,, improve the safety of lock after door leaf is subjected to external force collision so that the outer panels of lock still can be protected lock core when deforming.

To achieve these goals, improved door lock provided by the invention comprise lock body, with supporting lock core, outer panels and the wainscot of lock body, the back side of described outer panels is provided with the screw that the mounting screw on the front door with the interlayer door leaf cooperates.

The door leaf structure of the improved door lock of employing provided by the invention comprise the interlayer door leaf front door and Rear Door, be installed in lock body between front door and the Rear Door, be installed in the lock core that cooperates with lock body on the interlayer door leaf, cooperate corresponding outer panels and the wainscot that is installed on front door and the Rear Door with lock body, the head of lock core exposes front door, the back side of described outer panels is provided with screw, is tightened in this screw from the back side of described front door by screw outer panels is fixed on the front door.

The present invention is owing to directly be fixed on outer panels on the front door of interlayer door leaf; even if door leaf is subjected to external force collision and makes the front door distortion; outer panels all the time closely and front door combine; can be because of not forming the gap between front door distortion and the front door; be difficult to outer panels be prized, can play the effect of protection lock core with instrument.Said structure of the present invention has promoted the theftproof performance of security door greatly.

Fig. 1 is the schematic appearance of existing door lock.

Fig. 2 is the sectional drawing after Fig. 1 removes lock body.

Fig. 3 is the schematic diagram after door leaf is subjected to external force collision.

Fig. 4 is the schematic diagram of improved door lock of the present invention and door leaf structure.

The specific embodiment

See Fig. 4, the improved door lock of the present invention, comprise lock body 7, with supporting lock core 5, outer panels 1 and the wainscot 2 of lock body 7, the back side of described outer panels 1 is provided with the screw 13 that the mounting screw 12 on the front door 8 with interlayer door leaf 3 cooperates.

The door leaf structure of the above-mentioned improved door lock of employing provided by the invention, the front door 8 and the Rear Door 9 that comprise interlayer door leaf 3, lock body 7 is installed between front door 8 and the Rear Door 9 by screw 10, lock core 5 is installed on the interlayer door leaf 3 and cooperates with lock body 7, the screw at outer panels 1 back side is taken over the front door 8 of 4 insertion door leafs 3, with screw 6 with outer panels 1 and wainscot 2 correspondences be installed in door leaf 3 before, Rear Door 8, on 9, the head of lock core 5 exposes front door 8, the back side of described outer panels 1 is provided with screw 13, is tightened in this screw 13 from the back side of the front door 8 of door leaf 3 by screw 12 outer panels 1 is fixed on the front door 8.

Claims
