Abstract

The utility model discloses a door, particularly a multifunctional theftproof door having good safety performance. The multifunctional theftproof door comprises a door plate, a cipher lock 6 on the inner side of the door plate 6, a cover drum 8, and a lock pin 10. The utility model is characterized in that the cipher lock on the inner side of the door plate is fixed with a tapered cover 7, and the lock pin 10 is provided with an angle-shaped plate 9. The utility model which has the advantages of simple structure, easy fabrication, and good safety performance, etc. Is particularly suitable for being installed on safes and anti-theft doors for national treasuries of banks.

Description

Multifunctional theftproof door

The utility model relates to security door, the multifunctional burglary-resistant door that particularly safety is good.

Existing safety cabinet or bank exchequer door, its structure is made up of shop front steel plate, door lock, mechanical code lock, its weak point is: after the stranger is cut into hole with the electric drill punching or with gas flame, can pull out with medical minor diameter endoporus sight glass deciphering with the steel skewer, thereby open the door theft, fireproof performance is poor simultaneously, therefore very dangerous, in CN2120163U, disclose a kind of with steel through heat treatment, the high anti-drilling strongbox of hardness can not be prevented the cutting of gas flame.CN2051266 * * the isostructural strongbox of a kind of tank shell fire prevention sheet asbestos is disclosed in (application number 89200764.8), though fire prevention can not be prevented boring, anti-gas flame cutting performance is not good yet.Newly do not find outside door lock pin and mechanical code lock, to install the technical pattern that cone-shaped hood is peeped in anti-drilling through quenching, anti-through looking into.

The purpose of this utility model is exactly a kind of simple in structure, processing and manufacturing is easy, cost is low multifunctional burglary-resistant door of design.

The purpose of this utility model realizes by following structure:

The multifunctional burglary-resistant door comprises door-plate and at the coded lock of door-plate inboard, the cover tube, and lock pin is characterized in that: an intrinsic cone-shaped hood on the coded lock of door-plate inboard has the dihedral plate on lock pin; Cone-shaped hood and dihedral plate all can be selected the high-hardness plate through Quenching Treatment for use, after using the utility model, when the stranger makes composite armour behind the door for a long time with electric drill and Churn drill warp, if continue to bore cone-shaped hood and dihedral plate again, because of tapered cover and dihedral plate out of plumb shop front steel plate, can not center when making the drill bit rotary drilling, add the high rigidity of quenching, drill bit can not creep into, if firmly creep into by force, other immediately breaking of rod head, cone-shaped hood and dihedral plate tightly cover mechanical code lock and lock pin, therefore the steel skewer can not touch, endoscope can not be seen the cipher lock breach, can not decipher.

Advantages such as the utlity model has simple in structure, easy processing and manufacturing, cost is low, and safety is good especially are fit to be installed on the safety cabinet or as the bank vault security door and use.

Description of drawings of the present utility model is as follows:

Fig. 1 is an exemplary construction schematic diagram of the present utility model;

Fig. 2 is that the B of Fig. 1 is to view;

Fig. 3 treats as mutually for the A-A of Fig. 1;

Among the figure: steel plate, 5 is reinforced bolt, 6 mechanical code locks, 7 cone-shaped hoods, 8 cover tubes, 9 dihedral plates, 10 lock pins, 11 safety cabinet sidewalls in 1 shop front steel plate, 2 special cermacis plates, 3 bond layers, 4.

The utility model will be further described below in conjunction with drawings and Examples:

As shown in Figure 1: the utility model includes door-plate and at the password lock pin 10 of door-plate inboard, it is characterized in that: an intrinsic cone-shaped hood 7 on the coded lock of door-plate inboard has dihedral plate 9, as shown in Figure 3 as shown in Figure 2 on lock pin 10; Door-plate is by shop front steel plate 1, and interior steel plate 4 and solid special cermacis plate 2 formation composite armor panels between two steel plates are to increase its anti-brill, the performance of impact resistance.
