Due to the fact that the structure that the supporting plates organically combine two gate locks into one integral body is adopted by the sleeve lock for a gate, the sleeve lock for a gate can effectively prevent a committing person from using a knife to prize a gate lock, or using feet to knock the gate lock. The two gate locks with different structural forms are used for further reinforcing anti-theft safety performance on the basis that the supporting plates are used for enhancing anti-theft anti-prizing and anti-collision.

Description

A kind of Lock set for door

The utility model relates to a kind of lockset, belongs to the tool that changes of daily security personnel's apparatus.

Existing door lock generally fits a lock on a door, as spherical door lock, handle-door lock, built-in lock etc., but its antitheft safety of this mounting structure is all poor, pried open or rushed open easily, antitheft for strengthening, the someone takes to adorn the method for two locks on door, but this method is the simple superposition of two locks, can only be to prolong pick-proof, crashproof time, really not play the antitheft function of effective reinforcement.

The purpose of this utility model provides a kind of anti-theft security good, effectively pick-proof, crashproof dual fail-safe Lock set for door.

The utility model comprises the forward and backward supporting plate and two door locks on the positive and negative two sides that is symmetricly set on door, and wherein supporting plate is provided with the through hole that door lock is installed, and two door locks are separately positioned on two supporting plates.

The utility model is formed integrative-structure owing to adopt supporting plate that two locks are organically combined, the molecule that can effectively prevent to commit a crime is pried open with cutter or is rushed open door lock with riding, and further strengthen antitheft security reliability by the door lock of two different structure forms utilizing supporting plate to improve on pick-proof, the crashproof basis, and because two shared key kits of door lock, reduced the amount of carrying relatively, convenient and simple, only need a key just can open two locks, make it have simple in structure, economical and practical advantage.

Describe basic structure of the present utility model and principle in detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that schematic diagram is looked on a left side of the present utility model;

Fig. 3 is the cross-sectional schematic of the utility model supporting plate;

As shown in Figure 1-Figure 3, the utility model comprise be symmetricly set on the door just, before the anti-two sides, rear supporting plate 1 and two door locks 2, wherein supporting plate 1 is provided with the through hole 11 that door lock 2 is installed, two door locks 2 pass through two through holes 11 respectively on supporting plate 1, and the lock core of door lock 2 is arranged between two supporting plates 1, the door lock of An Zhuaning is when the robber forces open the door or rushes open like this, because supporting plate 1 organically combines two locks and is integral, supporting plate 1 plays an effect of effectively reinforcing, and lock core is enclosed between the supporting plate, make the robber when forcing open the door, be difficult to set about, be difficult to two locks are pried open simultaneously, also be not easy to pry open earlier a lock and pry open another lock again, strengthened the difficulty of forcing open the door greatly, effectively play pick-proof, crashproof effect.Be to strengthen the convenience that reliability that supporting plate 1 and door install and door lock are installed, further strengthen its pick-proof, crashproof function, above-mentioned supporting plate stamps out the mount pad 12 that concaves in the middle of 1 surface, and bends inwards around it and form the flanging 13 of pressing to a surface.Open door lock and further strengthen its anti-theft feature for convenient, one of above-mentioned two door locks are the spherical door lock or the handle-door lock 21 of single tongue pellet shot from a slingshot, another door lock is the built-in lock 22 of keyway formula locking bar, and the lateral location that supporting plate 1 is installed the through hole of spherical door lock or handle-door lock is provided with recess 14.Simultaneously, be to reduce the amount of carrying of key, above-mentioned spherical door lock or handle-door lock 21 and built-in lock 22 shared key kits, so only a key of need just can be opened two locks, makes to unblank conveniently and simple, further strengthens practicality of the present utility model.
