The specific embodiment

As shown in the figure, the utility model is a kind of drawer-lock, comprises housing, lock core structure and scalable dead bolt, and described lock core structure includes with the dead bolt that stretches and flexibly connects its flexible actuator of drive, and this actuator directly is connected with the push-and-pull handrail.

Below the contrast Figure of description further describes the utility model, but the utility model includes but not limited to method and structure cited in the example.

Embodiment 1

As Figure 1-3, drawer-lock comprises housing 1, lock core structure and scalable dead bolt 2.Described lock core structure includes actuator, back-moving spring 5, baffle plate 6 etc.

In the present embodiment, the shiftable valve 4 of actuator for moving horizontally, valve body are provided with curved groove 41.Flexible dead bolt 2 is perpendicular to the moving direction setting of shiftable valve 4, and its terminal curved groove 41 with shiftable valve 4 is slidingly connected.Curved groove 41 protrudes to flexible dead bolt 2 directions.Shiftable valve 4 one ends are connected with back-moving spring 5, apply outside active force to shiftable valve 4.The other end of shiftable valve 4 exposes to housing 1 and radially is socketed with push-and-pull handrail 3.Push-and-pull handrail 3 is the columnar structured of flanged pin 31, is socketed on outside the shiftable valve 4, is fixedly connected on the housing 1.The tongue of flexible dead bolt 2 is that square or wedge shape all can.

Preferably, be provided with baffle plate 6 in the shiftable valve movable passageway of described housing 1, baffle plate 6 inwardly protrudings have certain slope, make between baffle plate 6 and the shiftable valve 4 gap gradually thin.Baffle plate 6 is an elastic baffle, and as shown in Figure 2, baffle plate 6 back sides this flexible (as elastic plastic member) applies active force to it.The front of baffle plate 6 then is provided with the M shape chute of restriction following card division 42 motion tracks, as shown in Figure 4, M shape chute middle part be recessed to form neutral position 62, fixedly card division 42 prevents its slip.Preferably, the updrift side in neutral position 62 is provided with boss 61, and card division 42 can not be moved in the other direction.Described shiftable valve 4 is provided with the card division 42 of projection, can along with shiftable valve 4 deeply and with baffle plate 6 clampings, thereby with the fixed-site of shiftable valve.

Need at closing time, promote drawer by push-and-pull handrail 3 and close; Press shiftable valve 4 then, this moment, flexible dead bolt 2 slided along curved groove 41, is bent groove 41 ejections to exposing to housing 1 along with shiftable valve 4 moves inward; 42 of card divisions toward in, shown in Fig. 4 arrow, card division 42 can be crossed boss 61 and be fallen into neutral position 62 when arriving certain depth, this moment, scalable card division 42 was blocked by baffle plate 6, the action of closing the door is finished, drawer-lock is stable maintains the state of closing the door.

In the time of need opening the door, the user presses shiftable valve 4 once more, and move toward interior once more card division 42, jumps out neutral position 62, and shiftable valve 4 is resetted by back-moving spring 5 owing to lose the fixing of card division 42, and flexible dead bolt 2 is again in the retraction housing 1; Hook push-and-pull handrail 3 simultaneously and be pulled outwardly, can finish the action of opening drawer.

Embodiment 2

Shown in Fig. 5-7, drawer-lock comprises housing 1, lock core structure and scalable dead bolt 7.Described lock core structure includes actuator, back-moving spring 9 etc.

The tongue of described flexible dead bolt 7 is provided with chute 71 on one's body, and flexible dead bolt 7 ends then are provided with stopper 72; Described actuator is the axis of rotation 8 perpendicular to flexible dead bolt 7, axis of rotation 8 one ends and chute 71 are slidingly connected, be installed with the secter pat 81 of conflicting on the axle body of this end with stopper 72, the distance of shaft centers of the cambered surface of secter pat 81 and axis of rotation 8 is from different, in the present embodiment, the distance of shaft centers of the centre position cambered surface of secter pat 81 and axis of rotation 8 from less than the distance of shaft centers of end positions cambered surface and axis of rotation 8 from.Rotate when axis of rotation 8 rotations drive secter pat 81, just can prop up stopper 72 with axis of rotation 8 distances of shaft centers from bigger secter pat cambered surface part and make it downward, moving down in the retraction housing 1 of dead bolt 7 thereby drive is stretched.Flexible dead bolt 7 is connected with back-moving spring 9 and applies outside active force to it, when axis of rotation 8 revolutions, again prop up stopper 72 with axis of rotation 8 distances of shaft centers from less secter pat cambered surface part, this moment, the flexible dead bolt 7 of active force order of back-moving spring 9 moved up, and stretched out housing 1 again.The tongue of flexible dead bolt 2 is set to wedge shape, and doorframe can directly be pressed into housing 1 with the dead bolt 2 that stretches at closing time, realizes closing the door.

Axis of rotation 8 other ends are connected with the push-and-pull handrail 9 that exposes to housing 1.Push-and-pull handrail 9 comprise a draw ring (or other Any shape be convenient to pull-push piece that the user hands all can).This draw ring can with the shaft pertaining of axis of rotation 8 to fixedlying connected, perhaps as shown in Figure 4, be articulated and connected with the termination of axis of rotation 8, draw ring can be around the swing of the termination of axis of rotation 8, the position of corresponding draw ring then is provided with groove 11 on the housing 1, can be used for taking in draw ring, thereby can additionally not take the rescue interior space.

In the time of need opening the door, user's pull-up draw ring is to the position coaxial with axis of rotation 8, and the twisting draw ring drives axis of rotation 8 rotations, and secter pat 81 presses down stopper 72 and drives flexible dead bolt 7 and move down in the retraction housing 1, thus simultaneously outwards the pulling draw ring open drawer.Need at closing time, promote drawers by push-and-pull handrail 7 and close, flexible simultaneously dead bolt 7 by the active force of back-moving spring 9 by ejection to exposing to housing 1, the action of closing the door is finished, drawer-lock is stable maintains the state of closing the door.
