Description

Elecronic cipher anti-theft safe

The utility model belongs to a kind of daily necessities, specifically a kind of domestic safe.

Along with the development of urban and rural economies, the raising of living standards of the people, depositary bond and gold-silver ornaments in people's hand increase gradually, and make over is that the strongbox that organ, enterprise and institution are just bought also progressively moves towards family always.Because historical reasons, in the strongbox in the market, the small-sized strongbox that can adapt to family expenses is few, and,, at first be based on mechanical code lock even if also there are problems in existing " greatly " type strongbox, its number of password is few, and confidentiality is poor, uses inconvenient.Secondly, casing adopts the thin-slab structure sheet metal to process mostly, so theftproof performance is poor, can not reach the national standard of thief-resistant safe.

The purpose of this utility model is a kind of security performance height of design, the small cipher strongbox of good anti-theft effect.

Its main technical schemes is that this thief-resistant safe is by casing (1), door (2) and lock constitute, on the dead bolt (6) of lock body (13), a breach is arranged, and dead bolt (6) is installed in an end of eccentric shaft (15), the other end on the eccentric shaft that has torsion spring (14) (15) has Xiao (16) who inserts in snap close guide plate (9) hole, there is projection the lower end of snap close guide plate (9), one end of hinged support plate (11) on support (17) connects extension spring (12), the other end places the end face of electromagnet (10), and can block the projection of snap close guide plate (9).On the surface of door (2) electronic cipher button (4) is arranged, and the door-hinge (3) of door on (2) be positioned at the inside of door (2), door (2) has step with the cooperation place of casing (1), and casing (1) is the overall structure of castable.

The utility model has the advantages that simple in structurely, the strong security of reliable in action, safety, password not only will be inputed one group of correct password, and the certain skill of opening the door of GPRS, can open chamber door; The strongbox smooth surface does not have any origin of force, and door has only the slit at several millimeters of zero points with the junction of casing, has further improved theftproof performance, and the door-hinge structure of uniqueness also makes stealer have no way of doing it.

Fig. 1 is a structure chart of the present utility model.It is Figure of abstract.

Fig. 2 is the enlarged drawing of A among Fig. 1.I.e. Suo structure chart.

Fig. 3 is the left view of Fig. 2.

Fig. 4 is the B-B sectional view among Fig. 1.

Operating principle is: when safe door is closed under external force, dead bolt (6) is at the state of position I, pinned by tapered end (5), snap close guide plate (9) moves downward under the effect of eccentric shaft (15), arrives lower position, electromagnet (10) is under the release conditions, support plate (11) is pinned snap close guide plate (9) by spring (12) pull-up, thereby reaches the purpose of pinning door (2).When desiring the opening safety case, after must importing one group of accurate password, click key point simultaneously, electronic lock is an output signal, make the electromagnet energising, be in and treat attracting state, then, must in 2 seconds, in casing, push away door once a little, make (9) continue to move downward a small distance, at this moment, support plate (11) promptly by electromagnet (10) adhesive (if in 2 seconds, door (2) is not pushed away in casing a little, electromagnet (10) promptly cuts off the power supply, door (2) just can not be opened), eccentric shaft (15) is under the effect of torsion spring (14), rotate 45, drive snap close guide plate (9) and move upward, arrive upper dead center position, dead bolt (6) rotation 45 is in the state of position II, dead bolt (6) has an active force to tapered end (5), otherwise then tapered end (5) has a reaction force to dead bolt (6), because lock body (13), dead bolt (6) is installed on the door (2), so to the reaction force of dead bolt (6), it promptly is the reaction force of opposite house (2), because dead bolt (6) is in the position of II, and tapered end (5) can freely separate with dead bolt (6), door (2) is unlocked simultaneously.

Electronic password lock is an outsourcing piece.

Among Fig. 2, (7) are the anti-aluminium sheet through specially treated, and (8) are the cover plate of snap close guide plate (9)

Claims (4)

1, a kind of thief-resistant safe, constitute by casing (1), door (2) and lock, it is characterized in that on the dead bolt (6) of lock body (13), a breach being arranged, dead bolt (6) is installed in an end of eccentric shaft (15), Xiao (16) on the eccentric shaft that has torsion spring (14) (15) other end inserts in the hole of snap close guide plate (9), there is a projection lower end of snap close guide plate (9), a hinged end that is in the support plate (11) on the support (17) connects extension spring (12), the other end places the end of electromagnet (10), and can block the projection of snap close guide plate (9).

2, strongbox according to claim 1 is characterized in that on the surface of door (2) electronic cipher button (4) being arranged.

3, strongbox according to claim 1 is characterized in that the door-hinge (3) on door (2) is positioned at the inside of door (2), and door (2) has step with the cooperation place of casing (1).

4, strongbox according to claim 1 is characterized in that casing (1) is the monolithic construction of castable.
