Description
(1) technical field
The utility model relates to a kind of elevator door cutter.
(2) background technology
The effect of the door lock device of elevator is:
1. the engagement of gate and Room door is finished by this cutter.Gate is opened when closing and to be driven Room door and open and close.
2. when gate was opened, at first the tool arm closure meshed with Room door, drives Room door again and opens the door synchronously.Open the door put in place after, the door machine just close the door, close the door on earth before, the door cutter still remain closed, be in engagement with Room door, behind the door-closing in-place, the door cutter when door-closing in-place, tool arm opens the engagement of withdrawing from Room door, by interlock mechanism gate is locked simultaneously.
Existing elevator is with the shortcoming that the door cutter also exists: structure is complicated, and the door cutter shrinks and will lean on cam path and roller, perhaps uses complicated connecting rod mechanism.
(3) summary of the invention
Have the elevator complicated deficiency of door knife structure now in order to overcome, the utility model provides an elevator cutter a kind of simple in structure, reliable.
The technical scheme in the invention for solving the technical problem is: a kind of novel elevator door cutter, comprise a knife back plate and two parallel tool arms, described tool arm is positioned at the front of described door knife back plate, and the back side of described door knife back plate is hinged with rocking bar, and the head of described rocking bar is provided with belt wheel; The front of described door knife back plate also is provided with roller, and described roller is between described two tool arms, and two tool arms are hinged with described roller respectively; Described roller is connected by connecting rod with described rocking bar, and described connecting rod is between described roller and described door knife back plate, and an end and the described rocking bar of described connecting rod are hinged, and the other end of described connecting rod and described roller are hinged.
Further, the bottom in described door knife back plate front also is provided with second roller, and two tool arms are also hinged with described second roller respectively; The back side of described roller also is provided with hook, and the back side of described second roller also is provided with spring, and the other end of described spring hangs on the described hook.
The utility model in use, the belt wheel of rocking bar cooperates with driving band, driving band pulling belt wheel makes the rocking bar rotation, the rocking bar drivening rod pulling roller of rotation rotates, thereby will open with roller pivotally attached two tool arms.And when the rocking bar contrarotation, in like manner can be with two tool arm closures.
The beneficial effects of the utility model are: simple in structure, avoided complicated cam path mechanism or connecting rod mechanism, and simple installation, safe and reliable.
(4) description of drawings
Fig. 1 is two tool arms structural representations of the present utility model when opening.
Structural representation of the present utility model when Fig. 2 is two tool arms closures.
(5) specific embodiment
