Description

The double anti-theft device of security door

Technical field

The utility model relates to security door, is specially the double anti-theft device of security door.

Background technology

At present, each burglar-proof mechanism of existing security door is all to be controlled by same door lock, and this structure design exists very large problem, once door lock by violence shakedown, just can make all burglar-proof mechanisms lose efficacy, brings very large potential safety hazard to actual use.

Utility model content

For the problems referred to above, the utility model has designed a kind of double anti-theft device of security door, and it is independent of existing door lock and specialized designs, can effectively promote the security performance of security door.

For achieving the above object, the utility model is by the following technical solutions:

A kind of double anti-theft device of security door, it is characterized in that: comprise that one is independent of the latch that existing door lock arranges, whole latch is arranged on door-plate inner side completely, latch phase end of door plate has certain activity surplus, the head of latch can with its outer move stretch out and with corresponding jack engagement connection on doorframe, the afterbody of latch is connected a securing rod is set, securing rod extend on a coded lock and by coded lock and controls the mobile locking of whole latch and remove, above the corresponding door-plate of coded lock installation site, have a fan communicates and is convenient to the wicket that hand stretches into operator password lock with door-plate outside simultaneously.

Further, above-mentioned coded lock is arranged on door-plate inner side by a locating support.

Further, above-mentioned coded lock is electronic type.

Further, above-mentioned coded lock is mechanical, and it comprises a combination disk, uniformly in combination disk is provided with a plurality of slots, in each slot, install one can be flexible up and down plug-in unit, at least above with three the plug-in units locking of described pin lock fixed pole is connected.

Warning device while further, being provided with operating mistake on above-mentioned coded lock.

Further, above-mentioned wicket adopts sliding door type structure or one-sided pivot structure.

Further, on above-mentioned wicket, be provided with the second door lock.

Further, the afterbody of above-mentioned latch is provided with and is convenient to hand-held handle.

The double anti-theft device of the utility model design is totally independent of existing door lock, in actual use, even if existing conventional door lock is destroyed, also can not cause the inefficacy of double anti-theft device, can effectively promote the security performance of security door.

At this, above double anti-theft device is arranged on door-plate inner side completely, when opening the door, need the wicket on opening-door plate that hand is put in coded lock is operated, effective isolation door Wai visual angle, stops the cryptocompromise of coded lock, guarantees the safety of double anti-theft device.

In addition, for further strengthening the safety of double anti-theft device, on described coded lock, correspondence is provided with warning device, once Password Input mistake or plug-in unit are extracted mistake, will make warning device work and continue to send loud alarm song, the possibility that can effectively avoid coded lock to be decrypted, not only plays good warning threat effect to burglar, also can play to house-owner the effect of prompting simultaneously.

Accompanying drawing explanation

Fig. 1, structural representation of the present utility model;

The top view of Fig. 2, the utility model mechanical code lock.

The specific embodiment

As shown in Figure 1, a kind of double anti-theft device of security door, comprises that one is independent of the latch 2 that existing door lock 1 arranges, and whole latch 2 is arranged on door-plate 3 inner sides completely, and latch 2 phase end of door plates 3 have certain activity surplus.The head 21 of latch 2 can with its outer move stretch out and with corresponding jack engagement connection on doorframe, the afterbody of latch 2 is connected and a securing rod 22 and is set is convenient to hand-held handle 23, and wherein securing rod 22 extend on a coded lock 4 and by coded lock and controls the mobile locking of whole latch 2 and remove.

Corresponding door-plate 3 tops of coded lock 4 installation sites have a fan and communicate with door-plate outside and be convenient to the wicket 5 that hand stretches into operator password lock 4, described wicket 5 adopts sliding door type structure or one-sided pivot structure, the shape of wicket 5 can be arranged to circle, square, figure circle, rhombus etc., set as required in practice, simultaneously in order to promote safety, on described wicket 5, be also provided with the second door lock 51, in use, need to unblank to open.

Described coded lock 4 is arranged on door-plate 3 inner sides by a locating support 6.Coded lock 4 can be electronic type or mechanical type, adopt in the present embodiment the latter, whole mechanical code lock comprises a combination disk 41, uniformly in combination disk 41 be provided with a plurality of slots 411, be totally 25 of the five-element's five row in the present embodiment, corresponding minimizing or increase the number of slot 411 as required in practice, and can change the layout type of slot 411, in each slot 411, install one can be flexible up and down plug-in unit 42, at least above with three plug-in unit 42 lockings of described pin lock fixed pole 22 are connected, and its structure as illustrated in fig. 1 and 2.

The double anti-theft device of the utility model design is totally independent of existing door lock 1, in actual use, even if existing conventional door lock 1 is destroyed, also can not cause the inefficacy of double anti-theft device, can effectively promote the security performance of security door.
