Abstract

The utility model relates to an electric control safe with a reserve card. The electric control safe with the reserve card is added with a set of door lock starting mechanism with the reserve card on the basis of the structure of an electric control starting door lock. After the reserve card is identified through an encoder, a wedge mechanism is pushed, and then the electric control safe is unlocked. The aim of the utility model is that when the electric control starting door lock happens failure, the door lock starting mechanism with the reserve card can achieve the function that a door is emergently opened. The utility model has reasonable design, convenient use, large capacity and high reliability.

Description

Electric control safe with reserve card

The utility model relates to the door latch structure of a kind of safety cabinet, particularly a kind of safety cabinet.

Existing computer cipher safety cabinet generally adopts button to open the door, in case when the computer of safety cabinet partly broke down, button did not just have effect, the cabinet door can't be opened, and as seen, present computer safety cabinet is all having certain limitation aspect its practicality, the reliability.

The purpose of this utility model provides a kind of safety cabinet with standby card, and the button Computerized puzzle lock is modified into password for it and standby card is used, and can adopt standby card promptly to open the door when computer breaks down.

The door latch structure of Electric controlled safe generally is: keyboard → (defeated sign indicating number) electromagnet → (adhesive) computer plate → (unlatching) lock structure → promotion cabinet door; The utility model has increased a standby card door lock on this basis and has started structure, adopts standby card → (insertion) decoder → (promotion) to carve block structure → (unlatching) lock structure → promotion cabinet door.Adopt the lock core structure of standby card to comprise card socket, card, S type lock core, L type lock core, loam cake, slide block, matrix composition; It is bayonet socket that the space is arranged between loam cake and slide block, and slide block is between loam cake and matrix; L type lock core, S type lock core are formed by steel ball, upper and lower copper post, spring, linearly vertically intert between slide block and matrix, and place the loam cake below; Two bronze medal posts of S type lock core are that the S face is that basal plane is slightly high than contact surface between slide block, matrix by the face of touching, and S type lock core spring is pressurized not; Two bronze medal post contact surfaces of L type lock core are L face and basal plane water holding level state.

Now with reference to the accompanying drawings the utility model is described further:

Accompanying drawing 1 is that the utility model door lock starts FB(flow block).

Accompanying drawing 2 is the utility model structural representations.

Accompanying drawing 3 is that the N of accompanying drawing 2 is to view.

Accompanying drawing 4 is the utility model lock core structural scheme of mechanism.

Accompanying drawing 5 is B-B views of accompanying drawing 4.

Accompanying drawing 6 is accompanying drawing 5 lock core partial enlarged drawings.

As shown in Figure 1, the operating mechanism that the utility model has two covers to open the door, the one, use keyboard to open the approach of door under the normal condition, another is non-normal condition, uses standby card to open the approach of door.

As shown in Figure 2, the utility model door lock mechanism comprise computer plate 1, electromagnet 2, draw pin 3, decoder 4, plectrum 5, dead bolt 6, carve block structure 7, door-plate 8 is formed.The defeated sign indicating number of button is given the computer plate, opens door lock by the electromagnetic actuation zip after treatment; Another approach is: standby card injects decoder through bayonet socket, by decoder standby card is judged, promotes the slide block of lock core mechanism then, drives and carves block mechanism, and zip is opened, and promotes to open the door handle this moment, and plectrum 5 upwards slides, and dead bolt 6 is regained, and door lock is opened.

The utility model lock core mechanism such as accompanying drawing 4, Fig. 5, shown in Figure 6 are made up of bayonet socket 1, loam cake 2, slide block 3, matrix 4, S type lock core 5, L type lock core 6; Lock core 5, lock core 6 are formed by steel ball 8, copper post 9, copper post 10, spring 11, and vertically are interspersed in slide block 3, the matrix 4, place loam cake 2 belows.Lock-out state: two bronze medal post contact surfaces in the L type lock core 6 are that the L face is that basal plane 12 overlaps with slide block 3,4 contact surfaces of matrix, and two bronze medal post contact surfaces in the S type lock core 5 be S face and basal plane 12 not on same plane, the relative matrix locking of slide block.Opening: correct standby card 7 is inserted through bayonet socket 1, and the steel ball 8 in the S type lock core 5 is depressed by card 7, and the copper post 9 in the lock core 5 is to dropping to the bottom surface and basal plane 12 is held same horizontal plane, like this, S face, L face, same plane, basal plane place, actuating card 7, slide block 3 just relative matrixs 4 move left, thereby drive and carve block mechanism, make and draw pin to open, finish unlatching, when extracting standby card out, owing to the retardation of L type lock core is taken slide block 3 out of, finish lock-out state, all steel balls recover the pressure of loam cake is touched.

Various combination by S type lock core, L type lock core can form each different decoder, safe and reliable, and in addition, standby card is a kind of porous punch card, and the password capacity is big, strong security, the difficult outfit.

Claims

1, a kind of Electric controlled safe with standby card, comprise keyboard, computer plate, electromagnet, lock structure, cabinet, it is characterized in that it also has a standby card door latch structure, by computer standby card, decoder, lock core mechanism with carve block mechanism and finish, promote carve piece by bayonet socket by the work of decoder code-identifying band movable lock core mechanism by standby card, promote lock structure unlatching door lock by carving piece.
