According to diagram of the present utility model the utility model is elaborated below.

Fig. 1 be the utility model critical piece decomposition diagram.In the side of housing 10 opening 11 is set, dead bolt 20 passes in and out thus, and enclosure interior is equipped with fixedly the dead bolt support 40 of dead bolt 20 and the battery case 13 that can place dry cell.Dead bolt support 40 is provided with the guide channel 41 that can cooperate with dead bolt track 24, comes off from dead bolt support 40 for preventing dead bolt 20, also be provided with on the dead bolt support 40 can inserting bolt 25 connecting hole 21.Though bolt 25 is housed on the dead bolt 20, but for dead bolt 20 can be moved, direction along ng a path is provided with connecting hole 21, can insert the switch movable span 44 of the fixed bar 61 on the hand control switch in addition, also has the allocating slot 23 of central vertical direction on dead bolt 20 near reducing motor 30 places.Opposite side on dead bolt support 40 also is provided with gag lever post 22, the motion of restriction dead bolt 20 in the scope of the restriction protrusion 43 that gag lever post 22 is provided with on dead bolt support 40.Fixed cover 31 is equipped with in outside at the housing 10 inner reducing motors of installing 30, and fixed cover 31 is fixed on reducing motor 30 on the housing 10 by bolt 35, and the turning cylinder of reducing motor 30 is connected with rocking bar, and rocking bar comprises crank 50 and driving lever 51.The lateral surface of hand control switch 60 is uneven in addition, makes things convenient for the user to operate, and the medial surface of switch has a cylindrical fixed bar 61, and the end of fixed bar 61 is provided with the draw-in groove 62 of a circumferential.Fixed bar 61 is fixed on the dead bolt 20 by the switch movable span 44 usefulness split washers 63 of dead bolt support 40.Being provided with of split washer 63 can prevent that hand switch 60 from coming off from dead bolt 20, because that hand switch 60 and dead bolt 20 are integral is mobile, so the user manually can control the opening and closing of dead bolt 20 by operation.

Fig. 2 is a front schematic view of the present utility model, and housing 10 fronts are equipped with the automatic switch 70 that can control reducing motor 30 and can be manually controlled the hand switch 60 that dead bolt 20 opens and closes where necessary.In addition, 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 the battery case place from the outside.

The utility model critical piece schematic diagram under unlocking condition during Fig. 3, the driving lever 51 that links to each other with reducing motor 30 is connected with allocating slot 23 above the dead bolt 20, when reducing motor 30 rotates to clockwise direction, drive coupled driving lever 51 and also rotate to clockwise direction.Driving lever 51 outwards fully stretches out, and can prevent it because impact comes off from allocating slot 23, and these external driving lever 51 ends also are equipped with packing ring, can prevent that also driving lever 51 from coming off.In addition, in order to make crank 50 bigger radius of gyration is arranged, it is the edge of crank 50 that driving lever 51 is located at from the longer-distance place of motor shaft.The driving lever 51 of crank 50 inserts 23 li of allocating slots on the dead bolts 20, and when the driven by motor rocking bar rotated, the powered driving lever 51 of vertical direction moved up and down in allocating slot 23, and the power of horizontal direction then promotes dead bolt 20 and moves as the plane along track 24.When driving lever 51 when clockwise direction rotates, dead bolt 20 promptly moves right to the inside of housing 10, when dead bolt 20 was moved into ultimate range, the gag lever post 22 of dead bolt 20 1 sides was run into the restriction protrusion 43 of dead bolt support 40, dead bolt 20 promptly stops to move.

Fig. 4 be utility model at the critical piece schematic diagram that shuts under the state, reducing motor 30 is to rotation counterclockwise, drives the rocking bar that links to each other with motor shaft to counterclockwise rotating.Opposite with Fig. 3, dead bolt 20 is along with the rotation of rocking bar is outside mobile to housing 10 at this moment, and when dead bolt 20 outwards moved to ultimate range, the gag lever post 22 of dead bolt 20 1 sides was run into dead bolt 20 upper limit projections 43, and dead bolt 20 stops to move.

In addition, be provided with track 24 in the bottom surface of dead bolt 20, track 24 is stuck in the guide channel 41 of dead bolt support 40, dead bolt 20 is moved along guide channel 41 directions, and the degree of depth of the aspect ratio guide channel 41 of track 24 is high, and dead bolt 20 only contacts with dead bolt support 40 by track 24, therefore, do not need lubrication oil dead bolt 20 can easily move yet, reduced the load that friction brings for reducing motor 30.

In sum, the utility model is not by gear, moves but drive dead bolt 20 by the allocating slot on rocking bar and the dead bolt 20 23, therefore have stronger impact resistance, and noise is less.
