The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing:

Embodiment: to shown in Figure 6, the strongbox locking mechanism in the present embodiment comprises locking plate 1, spring 2, slide block 3, rotating disk 4, motor 5 and shell 6 as Fig. 1.Locking mechanism of the present utility model is mainly used in the strongbox, is used for locking parts such as the link gear of strongbox or handle, and matches with the strongbox control circuit, and opens by key or fingerprint acquisition device.When the utility model locking mechanism is in the lock state, can pin corresponding link gear, make strongbox not to be unlocked; When locking mechanism is in opening, no longer pin corresponding link gear, make that the guarantor user can the opening safety case.

Locking plate 1, spring 2, slide block 3, rotating disk 4 and motor 5 all are located in the shell 6, and the inwall of shell 6 is provided with the mounting groove of the above-mentioned parts of corresponding placement, and preferably, shell 6 is made by alloy material, and are divided into two parts up and down.Shell 6 front ends are provided with the dead bolt 11 corresponding openings with locking plate 1.Shell 6 rear portions be provided with one with the corresponding block 61 in locking plate 1 rear portion, it is second stopping means of dead bolt 11 whole retracted positions of corresponding locking plate 1, when dead bolt 11 all during withdrawal, block 61 can block locking plate 1, it is mobile backward to prevent that locking plate 1 from continuing.

Locking plate 1 preferably adopts the powder casting, and it comprises that a dead bolt 11 that is arranged on front end also can stretch out from the opening of shell 6 front ends.One side of dead bolt 11 is an inclined plane shape, makes by this inclined-plane of extruding dead bolt 11 to pusher; It is one plane that the another side of dead bolt 11 is, thereby utilize this plane can pin corresponding link gear.

Locking plate 1 center hollows out and forms a rectangular substantially disappearance portion 12.The rear portion of disappearance portion 12 is provided with the location division 121 of a projection, and particularly, location division 121 is platforms that a height that is arranged on disappearance portion 12 rears rises, and when slide block 3 relative locking plates move to 121 places, location division backward, just can't continue to move backward.In addition, level is provided with a reference column 122 on the front inner wall of disappearance portion 12, is used for the front end of retainer spring 2.

Locking plate 1 rear portion be provided with one with the corresponding snap ring 13 in shell 6 rear portions, first stopping means of dead bolt 11 whole extended positions of promptly corresponding locking plate 1, when dead bolt 11 all stretched out, snap ring 13 can block shell 6, prevented that locking plate 1 from continuing to move forward.

The shape of slide block 3 and disappearance portion 12 are complementary, its rear lower be provided with one with location division 121 corresponding grooves, and be arranged at before the location division 121, and locking plate 1 is slidably relatively.Level is provided with a locating hole 31 on slide block 3 antethecas, is used for the rear end of retainer spring 2.

Spring 2 supports and is located between the antetheca of slide block 3 and disappearance portion 12, makes slide block 3 be close to the biasing post 41 of location division 121 or rotating disk 4.Particularly, spring 2 one ends are set on the reference column 122, and the other end supports and is located in the locating hole 31.Because the existence of spring 2 under the state that stretches out of dead bolt 11, when pushing the inclined-plane of dead bolt 11, even motor 5 does not change, also can make locking plate 1 push backward and resilience by compression spring 2.

Rotating disk 4 is provided with a biasing post 41 towards the card of locking plate 1 one sides, and biasing post 41 is folded between disappearance portion 12 rear walls and the slide block 3, and the central axis on the card of rotating disk 4 opposite sides connects the power output shaft of motor 5.During the motor outputting power, drive rotating disk 4 by power output shaft and be rotated, drive eccentric shaft 41 again and be rotated.

Motor 5 connects the control circuit of strongbox.The instruction of control circuit acceptance of risk case miscellaneous part such as keyhole, code keypad or fingerprint capturer, the control motor is rotated by specific direction of rotation, when for example needing to unblank, motor 5 towards drive locking plate 1 backward travel direction be rotated, when needs locked, motor was rotated towards driving locking plate 1 proal direction; After motor 5 rotations, drive rotating disk 4 and eccentric shaft 41 thereof and be rotated simultaneously; Because eccentric shaft 41 is folded between disappearance portion 12 rear walls and the slide block 3, when eccentric shaft 41 rotations, can drive locking plate 1 and move forwards or backwards, make the dead bolt 11 of locking plate 1 from shell 6, to stretch out or to withdraw, thereby play the effect of locking or release.
