Abstract
The utility model discloses an improved door lock comprising a lock body, a lock cylinder matched with the lock body, an outer panel and an inner panel, wherein the back of the outer panel is provided with a screw hole matched with the mounting screw on the front door plate of a laminated door leaf. For the door lock, as the outer panel is directly fixed on the front door plate of the laminated door leaf, the outer panel and the front door plate are combined compactly all the time even the door leaf is subjected to external force impact to cause the front door plate to deform, thus avoiding the gap between the outer panel and the front door plate due to the deformation of the front door plate, being hard to lever the outer panel by tools and being capable of protecting the lock cylinder. The improved door lock greatly improves the anti-theft performance of the anti-theft door.
Description
Technical field
The utility model belongs to lockset, is specifically related to a kind of improved door lock and adopts 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.
The utility model content
The purpose of this utility model provides a kind of improved door lock and adopts the door leaf structure of this lock, so that the outer panels of the time lock of deforming after door leaf is subjected to external force collision still can be protected lock core, improves the safety of lock.
To achieve these goals, the improved door lock that the utility model provides 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 that the utility model provides 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 utility model 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 utility model has promoted the theftproof performance of security door greatly.
