Abstract

A kind of security door, comprise door leaf, doorframe and theftproof lock, described door leaf comprises internal hilar plate and external door panel, this door leaf is connected with described doorframe by hinge, the dead bolt corresponding position of the inherent theftproof lock of described doorframe is provided with stiffener, offers the through hole that the dead bolt for theftproof lock passes through on the described stiffener.The beneficial effects of the utility model are: after on the safe-guard door lock, the dead bolt of theftproof lock and secondary lock is crossing to doorframe by the internal hilar plate of door leaf and is crossing to the stiffener or second stiffener again, just in case door is prized, theftproof lock and secondary lock stress equalization, only there is shear stress, do not have other torsion, and only bear at theftproof lock under the situation of shear stress, it can bear the external force of hundreds of ton, so the utility model pick-proof performance is fairly good.

Description

A kind of security door

(1) technical field

The utility model relates to a kind of security door.

(2) background technology

In the prior art, on the safe-guard door lock after, the dead bolt of theftproof lock is crossing to doorframe by the internal hilar plate of door leaf, just in case the door by the picking lock tongue except bearing shear stress, also need to bear another one torsion, internal hilar plate and dead bolt easily by the sled bad.

(3) summary of the invention

When meeting sled in order to overcome security door in the prior art dead bolt stressed big, easily by the bad deficiency of sled, the utility model provides a kind of pick-proof performance good security door to door.

The technical scheme in the invention for solving the technical problem is: a kind of security door, comprise door leaf, doorframe and theftproof lock, described door leaf comprises internal hilar plate and external door panel, this door leaf is connected with described doorframe by hinge, the dead bolt corresponding position of the inherent theftproof lock of described doorframe is provided with stiffener, offers the through hole that the dead bolt for theftproof lock passes through on the described stiffener.

Further, described theftproof lock also has secondary lock, described secondary lock is connected by gangbar with described theftproof lock, and the dead bolt corresponding position of the described secondary lock in described doorframe inherence is provided with second stiffener, offers the through hole that passes through for the described secondary dead bolt of locking on described second stiffener.

The employed theftproof lock of the utility model is commercially available on the market common theftproof lock, and after door was shut, the key that rotates theftproof lock was opened first grade of theftproof lock, and the dead bolt of theftproof lock will be locked doorframe, drives gangbar simultaneously and also locks doorframe with secondary lock; Open second grade of theftproof lock in key, the dead bolt of theftproof lock continues to lock in the stiffener, and the dead bolt of secondary lock is also locked in second stiffener simultaneously.

The beneficial effects of the utility model are: after on the safe-guard door lock, the dead bolt of theftproof lock and secondary lock is crossing to doorframe by the internal hilar plate of door leaf and is crossing to the stiffener or second stiffener again, just in case door is prized, theftproof lock and secondary lock stress equalization, only there is shear stress, do not have other torsion, and only bear at theftproof lock under the situation of shear stress, it can bear the external force of hundreds of ton, so the utility model pick-proof performance is fairly good.

Fig. 2 is the lateral view of security door described in the utility model.

Fig. 3 is the structural representation at the dead bolt position of security door in the prior art.

Fig. 4 is a perspective view of the present utility model.

(5) specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

With reference to Fig. 1,2,4, a kind of security door, comprise door leaf, doorframe 1 and theftproof lock 6, described door leaf comprises internal hilar plate 2 and external door panel 7, this door leaf is connected with described doorframe 1 by hinge, dead bolt 3 corresponding positions of described doorframe 1 inherent theftproof lock 6 are provided with stiffener 4, offer the through hole that the dead bolt for theftproof lock 6 passes through on the described stiffener 4.Described theftproof lock 6 also has secondary lock 5, described secondary lock 5 and described theftproof lock 6 are connected by gangbar, the dead bolt corresponding position of described doorframe 1 inherent described secondary lock 5 is provided with second stiffener, offers the through hole that the dead bolt for described secondary lock 5 passes through on described second stiffener.

The employed theftproof lock 6 of the utility model is commercially available on the market common theftproof locks 6, after door shut, the key that rotates theftproof lock 6 is opened first grade of theftproof lock 6, and the dead bolt 3 of theftproof lock 6 will be locked doorframe 1, drives gangbar simultaneously and also locks doorframe with secondary lock 5; Open second grade of theftproof lock 6 in key, the dead bolt 3 of theftproof lock 6 continues to lock in the stiffener 4, and the dead bolt of secondary lock 5 is also locked in second stiffener simultaneously.

As shown in Figure 1, on the safe-guard door lock after, the dead bolt 3 of theftproof lock 6 is crossing to doorframe 1 by the internal hilar plate 2 of door leaf and is crossing to stiffener 4 again, just in case door is prized, 6 of theftproof locks are subjected to shear stress, do not have other torsion, shown in arrow among Fig. 1.And bear 6 of theftproof locks under the situation of shear stress, it can bear the external force of hundreds of ton, so the utility model pick-proof performance is fairly good.And as shown in Figure 3, on the safe-guard door lock of the prior art after, the dead bolt 3 of theftproof lock is crossing to doorframe 1 by the internal hilar plate 2 of door leaf, just in case the door by the picking lock tongue except bearing shear stress, also need to bear another one torsion, shown in arrow among Fig. 3, internal hilar plate and dead bolt are bad by sled easily.

Claims
