Abstract

The invention provides an elevator door tool assembly which comprises a bottom plate, a left tool arm, a right tool arm, an upper connecting rod and a lower connecting rod, wherein two ends of the upper connecting rod and the lower connecting rod are respectively movably connected with the left tool arm and the right tool arm, the bottom plate is provided with a contact assembly, the contact assembly comprises a contact rod and a contact, the contact rod is formed by a first contact rod and a second contact rod which are bent in a certain angle, the right end of the first contact rod is fixed on the bottom plate, the upper end of the second contact rod is provided with a contact, the contact is horizontally rightwards and is formed by more than two longitudinally distributed contacts, each of the contacts is formed by a nut and a bolt, and the bolt sleeves the nut. The elevator door tool assembly has the following beneficial effects that the contact assembly is fixed on the bottom plate, the opening and closing of a contact switch can be realized through the horizontal movement of the bottom plate, and action of shearing force produced by rotational opening and closing of the contact switch in the prior art can be successfully overcome.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an elevator door knife assembly. Background technique [0002] With the rapid development of science and technology and the heightening of building floors, elevators are used more and more frequently in daily life. As a means of transportation for going up and down stairs, it is closely related to the safety of people taking elevators. requirements are becoming more and more stringent. As an important part of controlling the switch of the elevator landing door, the elevator door knife plays an important role in the daily work of the elevator. [0003] Commonly used door knives include two types: synchronous door knives and asynchronous door knives. The synchronous door knives first realize the action of clamping the floor door linkage door ball, and then the car door and the landing door are linked together; the asynchronous door knives are It moves with the car door at the same time. Be...
