Abstract
The invention discloses an improved door lock which comprises a lock body, a lock core matched with the lock body, an outer panel and an inner panel, wherein a screw hole matched with a mounting screw on a front door panel of a sandwich door leaf is formed on the back side of the outer panel. Since the outer panel is directly fixed on the front door panel of the sandwich door leaf, even if the front door panel is deformed due to the external force applied to the door leaf, the outer panel is always closely combined together with the front door panel, a gap is not formed between the outer panel and the front door panel due to the deformation of the front door panel, and the outer panel is not easily pried off with a tool, so that the effect of protecting the lock core can be achieved. The anti-theft performance of the antitheft door is greatly promoted through the adoption of the structure.
Description
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.
