Fig. 3 is the structural representation of the litter of the utility model when inserting lock hole.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described:

Extremely shown in Figure 3 like Fig. 1; The described a kind of device that prevents the lift car accidental shifting of the utility model; Its structure is; It comprises the motor 2 that is arranged on the sedan-chair top board 1, but also comprises quadric linkage 3, connect micro-switch 5 sway and touch the litter 4 of the said micro-switch 5 that automatically resets of automatically reseting of elevator safety loop, and the lockplate 8 that is fixedly connected on car guide rail 7; The output shaft of said motor 2 connects the left end of said quadric linkage 3, and the right-hand member of quadric linkage 3 connects the left end of litter 4, and the micro-switch 5 that automatically resets is positioned at litter 4 tops; Said lockplate 8 offers lock hole 80, when said litter 4 when moving right, the right-hand member of litter 4 can insert said lock hole 80; When said litter 4 when moving left, the right-hand member of litter 4 can break away from said lock hole 80.Wherein, lockplate 8 is installed on whenever the corresponding position of door layer by layer.Further; Said quadric linkage 3 comprises long connecting rod 31 and short connecting rod 30; The output shaft of said motor 2 is articulated in the left end of said short connecting rod 30, and the left end of the right-hand member of short connecting rod 30 and long connecting rod 31 is hinged, and the right-hand member of long connecting rod 31 is articulated in the left end of said litter 4; This quadric linkage 3 is simple in structure, reliable operation.

As preferred embodiment, said litter 4 is provided with contact boss 40, and the said micro-switch 5 that automatically resets is provided with pulley 50, and it is simple and reliable for structure.When litter 4 past moving right, contact boss 40 touches pulley 50, thereby touches the micro-switch 5 that automatically resets, and then cuts off elevator safety loop; When litter 4 past moving left, contact boss 40 no longer touches pulley 50, and the micro-switch 5 that automatically resets just automatically resets, thereby connects elevator safety loop.
