To correspondence.
Compared with prior art, the utility model has the beneficial effects that the inside of elevator shaft is arranged in the utility model
There are rotatable two reinforcing rods, elevator door can be reinforced, prevents external impact from layer door being made to deform the feelings to fall off
Condition, so as to avoid the generation of elevator accident, while the present apparatus will not interfere the operation of elevator, and installation cost is low, be suitable for promoting
It uses.
Detailed description of the invention
Fig. 1 be the utility model proposes a kind of elevator door anti-drop device structural schematic diagram；
Fig. 2 be the utility model proposes a kind of elevator door anti-drop device elevator in watch view.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-2, a kind of elevator door anti-drop device, including holding tank 1, holding tank 1 are set to elevator shaft and are located at
On the inner wall of layer door two sides, and one end of holding tank 1 is corresponding with the middle position of layer door, and the other end is towards prolonging at the top of layer door
It stretches, two sides close to each other of holding tank 1 are disposed as being open, and the lower end of holding tank 1 is equipped with shaft 2, and holding tank 1
The position of shaft 2 is provided with mounting groove, and is fixedly installed with driving motor 3 in mounting groove, shaft 2 is defeated with driving motor 3
Axis connection out, holding tank 1 is close to one end of layer header, and the inner wall far from opening is equipped with electromagnet 4, and two shafts 2 are divided
It is not fixedly connected with one end there are two reinforcing rod 5, two one end of reinforcing rod 5 far from shaft 2 are welded with semi-circle gear 7, and two
Root reinforcing rod 5 is under horizontality, and length is equal with the width of elevator door, and two semi-circle gears 7 are intermeshed, and are reinforced
