The specific embodiment

Embodiment describes in further detail the present invention 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 like Fig. 1.Locking mechanism of the present invention is mainly used in the strongbox, is used for locking the parts such as link gear or handle of strongbox, and matches with the strongbox control circuit, and opens through key or fingerprint acquisition device.When locking mechanism of the present invention 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 powder casting, and it comprises that one is arranged on the dead bolt 11 of front end and can from the opening of shell 6 front ends, stretches out.One side of dead bolt 11 is an inclined plane shape, makes through 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 a protruding location division 121, particularly, location division 121 be one be arranged on disappearance portion 12 rears the platform that rises of height, when slide block 3 relative locking plates move to 121 places, location division backward, just can't continue mobile 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 through compression spring 2.Because spring 2 intensity can reach 5 times acceleration of gravity, the vibration that can effectively prevent locking mechanism opens by mistake opens.

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 through 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; In the time of for example need unblanking; Motor 5 courts drive locking plate 1 travel direction backward is rotated, and 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.

Locking mechanism of the present invention can be accomplished the withdrawal of locking plate 1 and a complete stroke of stretching out under the drive controlling of motor 5 and circuit thereof.Stretch out the ending phase of stroke at locking plate 1; Input pulse supplemental current under the cooperation of motor 5 at its circuit; Thereby simplified the testing circuit that puts in place, in 5 seconds time of the withdrawal of locking plate 1 and the whole impulse stroke of stretching out, the circuit of motor 5 was only worked 1.2 seconds; And the motor 5 and the circuit thereof of conventional strongbox locking mechanism must be all in running order in whole stroke, make power consumption of the present invention very low.
