In order to achieve the above object, the utility model provides a following technical scheme:

a lift car door prevents the safety device of opening by mistake, including L-shaped side lock, door end lock, pulley taking the form of L; the vertical edge of the side lock is fixed on the left side wall of the elevator car door, and the transverse edge of the side lock is tightly attached to the door surface of the elevator car door; the door end lock is positioned on the left side of the elevator car door, the transverse edge of the door end lock is tightly attached to the lower part of the transverse edge of the side edge lock, the upper end of the vertical edge of the door end lock is provided with a hole, and the upper end hole of the door end lock is hung on a door end fixing piece fixed on the door; the pulley fix on the upper right end shop front of door end tool to lock, the right-hand member of nylon rope is equipped with plastics handle, and the left end passes the pulley and ties in the perpendicular limit bottom of door end tool to lock, and the plastics anticreep of arcuation is detained on pulley upper portion for preventing the rope from taking off, and the plastics stopper that is used for making the nylon rope of left end just in time be in the state of relaxing is fixed on the nylon rope of plastics anticreep right-hand member.

Preferably, the side lock is made of stainless steel.

Preferably, the door end lock is made of aluminum alloy.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the safety device for preventing the elevator car door from being opened by mistake can prevent the elevator car door from being opened by mistake in the running process of the elevator, avoid safety accidents caused by the elevator car door being opened by mistake and further ensure the construction and production safety of the elevator in daily use; meanwhile, the operation mode is simple, and convenience is provided for site worker construction.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: 1. plastic anti-tripping; 2. a pulley; 3. a plastic stop block; 4. a plastic handle; 5. a nylon cord; 6. a door end fixing piece; 7. a side lock; 8. a door end lockset.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a safety device for preventing the elevator car door from being opened by mistake comprises an L-shaped side lock 7, an L-shaped door end lock 8 and a pulley 2, wherein the side lock 7 is made of stainless steel, and the door end lock 8 is made of aluminum alloy; the vertical edge of the side lock 7 is fixed on the left side wall of the elevator car door, and the transverse edge of the side lock 7 is tightly attached to the door surface of the elevator car door; the door end lock 8 is positioned on the left side of the elevator car door, the transverse edge of the door end lock 8 is tightly attached to the lower part of the transverse edge of the side edge lock 7, the upper end of the vertical edge of the door end lock 8 is provided with a hole, and the upper end hole of the door end lock 8 is hung on the door end fixing sheet 6 fixed on the door; pulley 2 fix on the upper right end shop front of door end tool to lock 8, the right-hand member of nylon rope 5 is equipped with plastics handle 4, and the left end passes pulley 2 and ties in door end tool to lock 8 perpendicular limit bottom, and the arcuation plastics anticreep 1 that is used for preventing the rope and takes off is detained on pulley 2 upper portion, and the plastics stopper 3 that is used for making nylon rope 5 of left end just in time be in the state of relaxing is fixed on nylon rope 5 of plastics anticreep 1 right-hand member.
