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 tool arm opened, and meshed with Room door, drove Room door again and opened the door synchronously.Open the door put in place after, a door machine is just closed the door, close the door on earth before, a door cutter still keeps opening, and is in engagement with Room door, behind the door-closing in-place, the door cutter is when door-closing in-place, tool arm shrinks the engagement withdraw 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 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, the back side of described door knife back plate also is provided with horizontal latch hook, described latch hook is installed in rotation on the back side of described door knife back plate, and the gib head of described latch hook is positioned at the outside of described door knife back plate; The back side of described door knife back plate also is provided with rocking bar and two limited posts longitudinally, and described rocking bar is between described two limited posts, and the bottom of described rocking bar is connected by extension spring with the afterbody of described latch hook, and the head of rocking bar is provided with belt wheel; The front of described door knife back plate also is hinged with connecting rod, and the two ends of described connecting rod are hinged with described two tool arms respectively, and described rocking bar also has connecting portion, and described connecting portion passes described door knife back plate and is connected with described connecting rod.
Further, described latch hook is located on one of them limited post, and described rocking bar is positioned at the inboard of described latch hook.
Further, also be provided with the location division of indent on the described latch hook, also be provided with the positioning convex rod that is positioned at described latch hook below on the described rocking bar, described latch hook leans on mutually with described positioning convex rod.
Further, the lower hinge of door knife back plate has second connecting rod, and the two ends of described second connecting rod are hinged with described two tool arms respectively.
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, latch hook rotates under the extension spring effect, when rocking bar goes to limited post, and no longer rotation, during the rocking bar rotation, by its connecting portion drivening rod rotation, thereby will open, realize opening the door with two tool arms of rod hinge connection.When closing the door on earth, latch hook rotation, rocking bar rotations that reset, two tool arms are closure again.
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 a Facad structure scheme drawing of the present utility model.
