Abstract

An elevator door knife device with novel link rods relates to the field of elevator door knife devices, and comprises a first circular arc plate, a second circular arc plate, a baseplate, a first link rod and a second link rod, wherein the first link rod comprises a link rod body and a connecting rod; a groove is formed in the connecting rod at the part connected with the link rod body; and the connecting rod is connected with the link rod body integrally to form a casting. Therefore, long-term use cannot cause the separation between the connecting rod and the link rod body; the operation is stable and reliable; the structure is firm; and the safety is improved.

Description

technical field [0001] The invention relates to the field of elevator door knife devices, in particular to an elevator door knife device with a novel connecting rod. Background technique [0002] At present, in the elevator door knife device, the door knife link and the bottom plate are connected by a connecting shaft. The door knife link is a plastic casting, and the connecting rod and the door knife link are fixedly connected. There are patterns or threads at the connecting part of the knife linkage, and its purpose is to increase the bite force. Since the door knife link is a plastic part, it is very easy to wear for a long time, which will cause the connecting rod and the door knife link to loosen or even fall off. Contents of the invention [0003] The purpose of the present invention is to provide a novel elevator door knife device with connecting rods, which will not cause the connecting rods to fall off during long-term use, has a firm structure, and works stably ...
