The specific embodiment

Fig. 1 is the utility model overall structure schematic diagram, at housing 10 movably dead bolt 20 is set, a side of housing 10 has pin hole 11, for the turnover of dead bolt 20 front ends, the dead bolt support 40 of flexible connection dead bolt 20 and the installing hole 12 of driven wheel of differential 52 are equipped with in housing 10 inside, one side of dead bolt 20 is provided with reducing motor 30 and transmission device, the position 13 of opposite side for placing dry cell.The front of housing 10 is provided with the automatic switch 70 of hand switch 60 and 30 runnings of control reducing motor.

Dead bolt support 40 is fixed on the housing 10, and its inwall is provided with guide groove 41, and dead bolt 20 bottom surfaces are provided with the track 24 that matches with this guide groove 41, and dead bolt 20 can be along guide groove 41 parallel moving like this.

For preventing that dead bolt 20 from coming off from support 40, at dead bolt support 40 circular hole 42 is set, be provided with on the dead bolt 20 along the strip hole 21 of guide groove 41 directions, set bolt 25 on the circular hole 42, and strip hole 21 is stretched out in its end, and its position, termination is greater than the width of strip hole 21.

Dead bolt support 40 upper edge tracks 24 directions are provided with chute 44, the connecting axle 61 at hand switch 60 back sides passes respective connecting 26 on this chute 44 and the dead bolt 20, the head end of connecting axle 61 has circular trough 62, and clamping snap ring 63 on it forms a fixed connection hand switch 60 and dead bolt 20.

Fixed cover 31 is equipped with in the outside of the reducing motor of installing in housing 10 30, fixed cover 31 is fixed on reducing motor 30 on the housing 10 by screw 33, the output shaft of reducing motor 30 is fixedlyed connected with drive bevel gear 51, drive bevel gear 51 and driven wheel of differential 52 engagements; The top of driven wheel of differential 52 fixedly driving lever 80 of nut 53, when reducing motor 30 started, driven wheel of differential 52 drove driving levers 80 and rotates, and driving lever 80 drives dead bolts 20 along guide groove 41 slips by allocating slot 23.

One side setting of dead bolt 20 can be made the allocating slot 23 of back and forth movement for driving lever 80, the outstanding male member 22 that forms of opposite side, restriction dead bolt 20 motions in two limit switch 43 scopes that male member 22 is installed on support 40.

As shown in Figure 2, there is " closing " and " unlatching " mark in the outside of hand switch 60, therefore is easy to know dead bolt 20 residing states by naked eyes.

For preventing to take away the battery in the housing 10, lid 90 also is housed at discharge position, pond 13 from the outside.

As shown in Figure 3, when unblanking, press automatic switch 70, reducing motor 30 beginnings are counterclockwise rotated, the drive bevel gear 51 that links to each other with reducing motor 30 is to rotation counterclockwise, drive nibble mutually with it and driven wheel of differential 52 and driving lever 80 also to counterclockwise rotating.

Driving lever 80 props up allocating slot 23 after counterclockwise rotating the left side also promotes left, and dead bolt 20 is along with driving lever 80 moves to housing 10 inside together, and the front end of dead bolt 20 is opened thereby make to lock from pin hole 11 withdrawals.

After dead bolt 20 enters housing 10 inside, door lock fully and is in the complete opening state, run into limit switch 43 at the male member 22 of allocating slot 23 another sides, reducing motor 30 stops operating.

As shown in Figure 4, press automatic switch 70 during locking, reducing motor 30 clockwise rotates, and the drive bevel gear 51 that links to each other with reducing motor 30 is to clockwise direction rotation, drive nibble mutually with it and driven wheel of differential 52 and driving lever 80 also rotate to clockwise direction.

Driving lever 80 props up the right of allocating slot 23 and promotes to the right after clockwise direction rotates, make dead bolt 20 along with driving lever 80 is outside mobile to housing 10 together, and the front end of dead bolt 20 stretches out from pin hole 11, thereby forms locking states.

The same when unblanking, dead bolt 20 to housing 10 outsides move a certain distance reach complete locking-in state after, the male member 22 of allocating slot 23 another sides is run into limit switch 43, reducing motor 30 stops operating.

Because hand switch 60 directly links to each other with dead bolt 20, therefore stir hand switch 60 dead bolt 20 is moved, realize opening and locking.

Light for dead bolt 20 is slided, the degree of depth height of the aspect ratio guide groove 41 of the utility model track 24, dead bolt 20 only contacts with dead bolt support 40 by track 24 like this.Therefore, do not need lubrication oil that dead bolt 20 is easily moved, reduced the load of friction and reducing motor 30.

The utility model is owing to be provided with motor and transmission mechanism in housing, in order to driving the motion of dead bolt, so automaticity is higher, rapid operation, saves time, and compared to prior art, the utility model is safety and convenient more.

The utility model transmits motor power by bevel gear and driving lever, can alleviate the impulse force that dead bolt produces, and has the simple advantage of dynamic structure.
