The specific embodiment
Referring to Fig. 1～Fig. 4, the utility model comprises indoor handle 1, tongue and groove dead bolt 14, dead bolt back-moving spring 5 and tongue switching mechanism (comprising axis of rotation 4, rotary sleeve 3 and rotary sleeve back-moving spring 2), and the dead bolt bar 7 of tongue and groove dead bolt 14 upper ends is equipped with dead bolt back-moving spring 5.
Outside the venturi portion of the left end of described rotary sleeve 3 and between the lockset shell 18 rotary sleeve back-moving spring 2 is housed, the left end of venturi portion is connected with described handle 1.Near this rotary sleeve 3 inner peripheral surface be provided with annular groove 16, between this annular groove 16 and this rotary sleeve right-hand member, be provided with axial pass trough 17.Right-hand member at this rotary sleeve 3 is provided with axial driving lever 8, is provided with reclinate group at the right-hand member of this driving lever 8 and colludes 9.Described axis of rotation 4 is rotatably installed in the described rotary sleeve 3, is provided with two relative projections 15 at the outer peripheral face of close described handle one end of this axis of rotation 4, and this projection 15 is slidingly matched with the axial pass trough 17 of described rotary sleeve 3 inner peripheral surfaces; Be provided with the thin neck axle 19 of same axial at the right-hand member of this axis of rotation 4, this thin neck axle 19 is fixedly supported in the lockset shell 18 by axis of rotation fixator 6.Right-hand member at thin neck axle 19 is provided with the flexible shifting block 20 of dead bolt, is provided with on described dead bolt bar 7 and the flexible shifting block 20 corresponding dead bolt bar projections 21 (referring to Fig. 4) of described dead bolt.
Described tongue and groove dead bolt bar projection 21 is under the effect of dead bolt back-moving spring 5, when static (not being subjected to external force), make the flexible shifting block 20 of described dead bolt be positioned at certain position, in conjunction with the twisting force of rotary sleeve back-moving spring 2, make handle 1 not have always to be in certain position under the situation of external force jointly.
Fix a bayonet socket plate axle 12 dialling on the lockset shell that colludes 9 one sides of described driving lever 8, on this bayonet socket plate axle 12, the bayonet socket plate 11 that can rotate is housed, between this bayonet socket plate 11 and the bayonet socket plate axle 12 torsion spring (not shown) is housed, so that bayonet socket plate 11 is produced clockwise elastic torque.Be provided with on described tongue and groove dead bolt 14 right sides and carve mouthful (or a hole) 13, the upper end of described bayonet socket plate 11 is colluded 9 correspondingly with dialling, and the lower end of this bayonet socket plate 11 is with described to carve mouth 13 corresponding.
The projection 15 that is located at the axial pass trough 17 of described rotary sleeve 3 inner peripheral surfaces and is located on the described axis of rotation 4 is evenly arranged two along circumference respectively.
The top of key 10 of the present utility model is closed normal key and is prolonged, and makes its top can stretch out lock core the inner, so that push up the upper end of bayonet socket plate 11.
Operating principle of the present utility model is described as follows:
1, at the indoor handle that can dally: at the indoor handle 1 that do not spur, the annular groove 16 in the projection 15 on the axis of rotation 4 and the rotary sleeve 3 is corresponding, and rotary sleeve 3 can not rotate by driven rotary axle 4 when rotating handle 1, and handle 1 can dally.After the design lost motion functionality, just can make axis of rotation 4 rotations after having only dead bolt to clamp down on to be disengaged.If do not design lost motion functionality, be easy to generate and do not spur just rotation by force of handle, this moment, the shifting block 20 of axis of rotation 4 front ends can be stirred dead bolt bar 7, causes the damage of lock members easily because dead bolt is clamped down on.
2, at indoor opening the door (referring to Fig. 1): pulling handle 1 is moved to the left rotary sleeve 3, projection 15 on the axis of rotation 4 is entered in the axial pass trough 17 in the rotary sleeve 3, dial and collude 9 upper ends of stirring bayonet socket plate 11 left, make bayonet socket plate 11 rotate counterclockwise certain angle (referring to the bayonet socket plate 11 ' after rotating among Fig. 1), what the lower end of bayonet socket plate 11 broke away from dead bolt 14 carves mouthfuls 13, can remove clamping down on of 11 pairs of dead bolts of bayonet socket plate, this moment, dead bolt 14 can freely stretch; Rotate handle 1 subsequently again and just can rotate together by rotary sleeve 3 driven rotary axles 4, the flexible shifting block 20 of the dead bolt on the axis of rotation 4 is stirred the groove of dead bolt bar 7, thereby makes dead bolt 14 withdrawals, reaches the purpose of normal door.Handle 1 (with rotary sleeve 3) resets under the effect of rotary sleeve back-moving spring 2 recovery elastic forces.
3, close the door outdoor: referring to Fig. 1, if close the door outdoor, because the effect of clamping down on of bayonet socket plate 11, dead bolt 14 is retractable not, so door can not be locked by lockset.Have only key 10 is inserted lock core, the upper end of bayonet socket plate 11 is stirred in the inner of the prolongation of key 10, make bayonet socket plate 11 rotate counterclockwise certain angle (referring to the bayonet socket plate 11 ' after rotating among Fig. 1), what the lower end of bayonet socket plate 11 broke away from dead bolt 14 carves mouthfuls 13, can remove clamping down on of 11 pairs of dead bolts of bayonet socket plate, this moment, dead bolt 14 can freely stretch, can be with on the door lock.Like this, be not with key just can not lock a door, effectively prevented to be locked in situation outdoors.
