The specific embodiment
On axle 110 in the lock box pack into by the axis hole on it 24 from Fig. 1 and the fan-shaped as can be seen dead bolt 20 of Fig. 2, can in 90 degree left and right sides scopes, pivot.The planar thickness of the height of the circular cylinder 31 of block 30 and the height of first chute 130 and dead bolt 20 is approaching substantially, and its motion is also carried out in same plane.
In conjunction with Fig. 3 and Fig. 4, when assembling, earlier dead bolt 20 is packed into, then the circular cylinder 31 of block 30 is packed into first chute 130 in the lock box, this chute is made up of with an inner cylindrical wall face 132 that is located at its opposite a semi-cylindrical 131 that is located in the lock box, distance between the two just in time is the annulus width of the circular cylinder 31 of block 30, but need guarantee the slip cooperating relationship between them.Block 30 pack into the back its on cylinder 38 cover on dead bolt 20, when latched position, the cylinder 23 that resets on the dead bolt 20 should be positioned at the triangular groove 35 of block 30.
Be in latched position at dead bolt 20, when just the follower 50 of electric device is in extended position, the head 59 of follower is positioned at the top of second chute 150, the circular cylinder 31 of limit stop 30 is along rotation counterclockwise among the figure, because block 30 first facades 32 have withstood first facade 21 of dead bolt, so dead bolt 20 is locked.
Under dead bolt 20 blocked states, if the situation that illegal brute force is unblanked takes place, that is to say, a very big external force is applied to the handle of safe door or draws retaining device, this external force at first reaches second facade 22 of dead bolt 20, reach the circular cylinder 31 of block 30 again through first facade 21 of dead bolt, reach the head 59 of follower again, second chute 150 by lock box 10 passes to lock body at last.It should be noted that, the transmission of above-mentioned external force all is to be undertaken by the mode of plane contact, and this external force through be broken down into after solid head 59 of follower respectively with head second facade 52 vertical and and head the 3rd facade 53 vertical two component, it is concentrated to have reduced stress thus.To be connected with driving between the electric device 40 be flexible to follower 50 in addition, and have only follower head 59 to bear above-mentioned external force, screw mandrel 42 does not bear or bears external force seldom, thereby the damage of having avoided external force to directly act on electric device and having caused, the ability that the illegal brute force of resistance of whole lock body is unblanked is strengthened.
Fig. 5 shows the structure of back-moving spring 70, Fig. 6 show this spring pack into lock box 10 and with the assembly relation of dead bolt 20.This back-moving spring is a biasing spring, its big ring spring 71 is set on the axle 110, ringlet spring 72 is set on the interior post 111 of lock box, free end 73 is stuck in the groove 25 on the dead bolt 20, and this biasing spring keeps applying to dead bolt 20 and makes it have the power of tending to counter clockwise direction rotation shown in Figure 1 after assembling.
The unlatching and the reseting procedure of this turning-bolt lock are as follows:
When the input unit of strongbox, receive as keyboard, magnetic card or fingerprint scanner etc. that 40 actions of control electric device are moved follower 50 behind the correct unlock instruction, remove locking to dead bolt 20.In the present embodiment, receive and give after the open command motor 41 logical forward currents, it is just being changeed and drive follower 50 and move, cause to make second chute 150 vacate the space 151 that cylinder 31 parts are entered along the indentation direction.This moment is if rotate the safe door handle or draw retaining device with external force, dead bolt 20 overcomes the resistance of biasing spring 70 under this external force effect, rotate to clockwise direction shown in Figure 2, lock first facade 32 that 20 first facade 21 forces in cylinder 31 this moment, pushing away cylinder 31 and turning over an angle and make the part of cylinder 31 enter the second chute space of having vacated 151, and then dead bolt 20 turns about 90 degree to the enable possition along clockwise direction shown in Figure 2; When said process began, the projection 23 on the dead bolt was arranged in the groove 35 on the block, went to enable possition while cylinder 31 at dead bolt 20 and turned over an angle, and the projection 23 on the dead bolt 20 breaks away from grooves 35.And arrive enable possitions at dead bolt 20, the projection 23 when the fan-shaped opening edge of groove 35 is just in time aimed at dead bolt 20 and resetted on it must through movement locus on.
After imposing on handle or drawing the external force of retaining device to cancel, dead bolt 20 is resetted to latched position from the enable possition, dead bolt rotates to counter clockwise direction shown in Figure 2, the fan-shaped opening edge of the groove 35 of the projection 23 of this moment on the dead bolt 20 from the block 30 enters groove 35, and force in another facade 36 of groove 35, thereby drive the space 151 that block 30 goes back to the angle that is turned over when opening and vacates second chute 150 that its cylinder 31 occupies when opening.After dead bolt 20 and block 30 reset, control circuit makes its counter-rotating and drives follower 50 for motor 41 logical reversing the currents and moves along stretching out direction, enter the space 151 of second chute 150 fully up to the solid head of follower, block 30 is defined once more, and dead bolt is also locked once more.
Fig. 7 illustrates a kind of turning-bolt lock or used electric device of other strongbox of being used for, wherein motor 41 is commercially available direct current generators, this motor can be fixed in the cavity 17 that is provided with on the lock box 10, the motor drive shaft hole 45 on the screw mandrel 42 of packing into, because the moment of being transmitted is very little, can adopt easy interference fit.Casket body 60 is except that outline and second chute 150 are slidingly matched, and the wall of its inside casing both sides also will be slidingly matched with sleeve pipe 56 lateral surfaces, when sleeve pipe 56 straight lines move, promotes casket bodies 60 moving linearlies by forcing in cover two springs 67,68 thereon.So structure is set, and one of them effect is exactly when impact external force takes place, and the lock body vibrations are violent, sleeve pipe 56 is deviate from from casket body 60, thereby caused fault.Adopt above-mentioned two springs 67,68 then can play the effect of damping vibration, make the maintenance certain pressure between sleeve pipe 56 and the casket body 60 simultaneously, prevent to be shaken backward dislocation.
Another effect that these two springs are set is that buckle 61 is play the guiding role from the position that extreme position (just stretch out put in place and indentation put in place) carries out the transition to the screw thread snap fastener of screw mandrel 42.As Fig. 8 and shown in Figure 10, on screw mandrel 42, be provided with two gathering sills 47 and 48, when the two legs 63,64 of buckle 61 when being arranged in gathering sill 47 and 48 just in time follower 50 be in above-mentioned extreme position, till no matter forwarding unlatching to from dead bolt 20 from latched position, still dead bolt 20 resets to latched position from the enable possition, the two legs 63,64 of buckle 61 all will carry out the transition to position with the wire rod thread snap fastener from the gathering sill on the screw mandrel 42 47 or 48, and one of necessary condition that carries out the transition to this position is exactly 63,64 1 end thrusts of two legs that need to give buckle 61.And being set, these two springs 67,68 just satisfied this condition.From Fig. 7, Fig. 9 and Figure 12 as can be seen, these two springs 67,68 are enclosed within respectively on two cylindrical shoulders 57,58 of sleeve pipe 56 and by two end faces location of cuboid of its middle part projection, and the other end of spring 67,68 is limited by two end faces 62 and 69 of casket body 60 cavitys respectively, so no matter in what position, these two springs 67,68 all to sleeve pipe 56 in other words the two legs 63,64 of buckle 61 keeping certain end thrust.Say from another point of view, cooperate the two legs 63,64 that changes into by a buckle 61 of above-mentioned usefulness to form with the screw thread of screw mandrel 42 traditional screw mandrel screw thread and cooperate, an outstanding technique effect is exactly can avoid transferring damage because of killing of wire rod thread and screw thread causes motor 41 to be blocked.Above-mentioned stall has two kinds of possibilities, one, and the position on the buckle is forbidden or angular deviation generation screw thread is killed; Its two, other mechanical breakdown takes place, the cylinder 31 of block 30 fails to reset, and causes follower 50 to run into obstacle when direction moves to stretching out.Because in technical scheme of the present invention, the two legs 63 of buckle 61,64 with corresponding hole 43, between 44 and and screw mandrel 30 screw threads between have certain clearance, leg 63,64 also have certain elasticity, they are flexible with cooperating of screw mandrel 42 screw threads, even above-mentioned two kinds of situations take place, the two legs 63 of buckle 61,64 with screw mandrel 42 screw threads only can produce skidding, be that screw mandrel 42 is in normal rotation, but straight line does not take place for buckle 61 and sleeve pipe 56 moves, thereby also the stall phenomenon can not take place, thereby avoided motor 41 that impaired phenomenon takes place because of stall.
These two springs are set, and to also have an effect be to be in latched position when dead bolt 20, by block 30 follower 50 is stopped under external force, and when this moment, control circuit rotated it for motor 41 logical forward currents, sleeve pipe 56 compression springs 68, thereby guarantee not take place the stall phenomenon, after external force removes, follower 50 will slide into the enable possition under the effect of spring 68, still guarantee the unlatching of lock; When dead bolt 20 is in the enable possition, there is external force to stop and by back-moving spring 70 dead bolt 20 returned to latched position, block 30 has occupied the space of follower 50 heads, and when this moment, control circuit rotated it for motor 41 logical reversing the currents, leading screw 42 will compress spring 67, thereby guarantee the stall phenomenon does not take place, after external force removes, follower 50 will slide into locked position under the effect of spring 67, guarantee closing of lock.
Figure 13 and Figure 14 illustrate the structure of lock box 10 of the present invention and lid 80, wherein, two cylinders 18,19 are used for fixing a microswitch, this switch is used to detect dead bolt 20 and whether has been in unlatching or lock-out state, when dead bolt 20 arrives the enable possition or is reset to from the enable possition the process of latched position from latched position, dead bolt 20 can touch this switch, thereby produces a signal of telecommunication.In lock box, also be provided with three cylinders 12,13,14 that are used to install control circuit board, and the breach 15,16 of connector mounting.
