Abstract

The utility model relates to the field of lifts, in particular to a door vane. The door vane comprises a door vane bottom plate, a long tool arm component, a short tool arm and a long pull rod. The long tool arm component comprises a long tool arm. Lateral frames are disposed on two sides of the door vane bottom plate. Rotary columns at two ends of the long tool arm are rotatably disposed on the lateral frames. A retaining bar is disposed on a rotating side of the long tool arm. A mounting plate is disposed at the front end of the short tool arm. Two ends of the mounting plate are rotatably disposed on protrusions of the door vane bottom plate. A hole is arranged on one side of the door vane bottom plate. The long pull rod penetrates through the hole to be connected to a cam seat of the door vane bottom plate. The long pull rod drives the cam seat to extrude the short tool arm in linkage with the long tool arm so as to close the door vane. The door vane has the advantages that the tool arms and the door vane bottom plate are formed by one-step aluminum casting, the lift door vane uses a standard bush and threaded connection, if one part is damaged, the damaged part can be replaced independently, maintenance cost during usage can be saved more, and the door vane is more widely applicable by using the pull rod to drive the door vane to move.

Description

A kind of cutter

Technical field

The utility model relates to the elevator field, especially a kind of cutter.

Background technology

Elevator door knife is comprised of door cutter base plate, door cutter tool arm, attaching parts.The conventional door cutter adopts attaching parts directly to connect, because the attaching parts model features is single, can't be applicable to various elevators, and Applicable scope is little, installs and changes also trouble.

Summary of the invention

In order to solve the little technical matters of above-mentioned attaching parts Applicable scope, the utility model provides a kind of cutter.

The technical solution of the utility model is as follows:

A kind of cutter, comprise a cutter base plate, the rimmer knife arm component, short sword arm and long draw, the rimmer knife arm component comprises the rimmer knife arm, described door cutter base plate both sides are provided with side frame, the Rotational Cylindrical at described rimmer knife arm two ends is rotatably mounted on the side frame, described rimmer knife arm rotating side is provided with gear stick, described short sword arm front end is provided with adapter plate, described adapter plate two ends are rotatably mounted on the convex body of cutter base plate, door cutter base plate one side is provided with hole, described long draw passes hole and is mounted on a cam chair of cutter base plate, drives the closure that the motion of cam chair extruding short sword arm interlock rimmer knife arm realizes the door cutter by long draw.

As preferably, described rimmer knife arm component also comprises fixing body and oscillating bearing, the rimmer knife arm bottom of described Rotational Cylindrical opposite side is equipped with fixing body, be provided with oscillating bearing with the fixing body of hole homonymy, described oscillating bearing pushes the spring perch that is installed on the rimmer knife arm, spring perch is provided with little spring, and oscillating bearing connects short rod.

As preferably, two ends, the outside, middle part, described door cutter bottom are provided with press spring base A and press spring base B, are provided with compression spring A between rimmer knife arm and the press spring base A, are provided with stage clip B between short sword arm and the press spring base B.

As preferably, described cam chair is provided with cam.

As preferably, described long draw connects cam chair by attaching parts A.

As preferably, described short rod connects oscillating bearing by attaching parts B.

Use the technical solution of the utility model, door cutter tool arm and door cutter base plate adopt aluminium die casting one-shot forming, traditional door cutter base plate and door cutter tool arm all are sheet metal component, process by punch press, because its cumulative limit of machinework repeatedly is larger, and the easy resilience of panel beating and distortion, in use precision is difficult to guarantee; Conventional door cutter tool arm adopts rivet pin to be connected with the connection mode of door cutter base plate, if one of them damage parts must be changed whole parts even whole door cutter, this elevator door knife is adopted as the standard lining and is threaded, if one of them damage parts only need be changed the part of damage, more save the maintenance cost in using; Adopt the motion of pull bar drive door cutter, this structure Applicable scope is wider, and being used in only needs the replacing pull bar just passable on the different elevator doors.
