Description

Fixing device for anti-pry of built-in door lock

The utility model belongs to the bracing means of door lock, and or rather, it is with pick-proof, hits the structure that plate is reinforced at existing door lock.

The esidential building room, door lock (built-in lock) all is equipped with in the guest room in hotel, and various office occupancy on door, with as shutting conveniently, play the security and anti-theft effect again.As everyone knows, existing a large amount of door lock (built-in lock), although the type of built-in lock is different, and done well-designed, to the crime molecule generally adopt screwdriver, steel disc chi, chisel, knife to insert from caash bar, with the dead bolt of the built-in lock keeper of dragging on, steal to pry open the door row of entering the room, and the crime molecule hits the door of fiercelying attack with pedal, wing, door is rushed open the row robber's that enters the room means, with regard to present all kinds of door built-in locks, its protection capability is very poor.

The utility model is the bracing means at present door lock design; it can prevent that door lock from the possibility of general crime taking place, and helps developing the stable and united sound social atmosphere in the whole nation, to maintaining public order; protection country, collective and individual's property has certain safety assurance.This door lock pick-proof hits bracing means, and the existing ability that prevents that door lock from being pried open or rushing open has both artistic and practical and economical and practical characteristics again, is suitable for domesticly generally promoting the use of.

The purpose of this utility model, it is the deficiency that is to overcome above-mentioned door lock, under the condition that does not change door and lock, opposite house, lock carry out pick-proof and hit reinforcing to adopt door lock pick-proof gusset plate and crashproof gusset plate to come respectively, to reach safe and reliable, simple in structure, processing and manufacturing is easy, economical and practical, and be suitable for the general bracing means of present all kinds of door lock.

According to the purpose of this utility model, the new design structure and the technical measures that are adopted on the structure of bracing means are as follows: 1. the tapered end of a pick-proof of design is reinforced flap, the circular hole face of this reinforcing flap is inserted in tapered end and between retainer and door-plate, after being compressed by retainer, to roll over the shape plate with screw again and be fixed on the door, in order to play the effect that tapered end can not be pried open of reinforcing; 2. design the caash bar of a pick-proof and reinforce the dihedral plate, it is contained in the moulding behind of doorframe, be screwed on doorframe, it is corresponding with tapered end reinforcing flap that this Anti prizing door frame bar is reinforced the dihedral plate, and keep loosening contact, the possibility of being pushed aside with knife etc. by the molecule of committing a crime in order to the dead bolt that prevents door lock; 3. at the back side of door lock, design two gusset plates, be stuck on lock body and the keeper, and the gusset plate on the lock body is fixed on the door-plate with screw, the gusset plate of keeper is fixed on the doorframe, thereby the lock body of door lock and keeper are reinforced, had the ability that the molecule that prevents to commit a crime rushes open door.

The door lock pick-proof of finishing by above-mentioned new design structure and technical measures hits bracing means, the enough anti-prizing type locks of energy reinforce flap and caash bar is reinforced the pick-proof structure that the dihedral plate is formed, this structure molecule that can prevent to commit a crime is pried open the possibility of door lock with knife etc., and respectively lock body, keeper are reinforced the door lock anti-collision structure of being formed with gusset plate, the molecule that can prevent to commit a crime rushes open the possibility of door lock with pin etc.This pick-proof hits bracing means, and is simple in structure, and installation and processing is economical and practical, is particularly suitable for the pick-proof of existing door lock is hit reinforcing, helps protecting country, collective and individual's property safety.
