Device has two same vertical plane tops for being separately positioned on intermediary transfer belt and the same vertical plane bottom of the second transmission belt, described
Performs device includes spring stop, spring, inserted link, block, plate, and the spring stop is fixed in car top, the spring with
Inserted link is connected, and the inserted link is provided with the block being engaged with shifting block close to the position of spring, and the plate is fixed on leading for elevator
In rail gantry or well enclosure, and the plate is provided with the jack matched with inserted link.
As further scheme of the invention, plate is designed with each layer of elevator.
It is used as further scheme of the invention, spring stop, spring, inserted link and plate the lateral car edge side from car
To setting gradually.
As further scheme of the invention, first transmission belt, intermediary transfer belt and the second transmission belt are rubber
Transmission belt or chain belt or other transmission devices.
Compared with prior art, the advantage of the invention is that：The present invention can always be protected when car door is not completely closed
Hold the lockup state to car, the accidental movement of elevator cage that can avoid occurring when gate is not completely closed completely it is serious
Accident, realizes and farthest reduces the unexpected caused security risk of elevator, safety and passenger to protecting lift facility
Personal safety it is significant；Especially, the present invention have the advantages that it is simple in construction, safe and reliable, easy for installation, can nothing
Destructively it is installed in existing lift facility, there is conspicuousness practical value to the security for improving and improveing existing elevator.

Embodiment
The present invention is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1-2, it is a kind of to prevent the safety device of car accidental movement, including transmission device and performs device, biography
Dynamic device includes the first drive 1, the second drive 2, enabling motor 3 and main transmission bar 4, enabling motor 3 by power transmission shaft with
First drive 1 and the second drive 2 are connected, and can synchronously drive the first drive 1 and the second drive 2 to operate, the first transmission
Wheel 1 is connected with elevator cage door, and main transmission bar 4 is provided with the first driving wheel 5, the middle driving wheel 7 of driving wheel 6 and second, main transmission bar 4
Both sides be respectively equipped with the first driven pulley 8 and the second driven pulley 9, the first driving wheel 5 passes through the first transmission belt 10 and the second transmission
