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

A kind of elevator door knife system that has novel link rod
Technical field
The present invention relates to elevator door knife system field, be specifically related to a kind of elevator door knife system that has novel link rod.
Background technology
At present; In the elevator door knife system, is connected through adapter shaft between door cutter link rod and the base plate, a cutter link rod is a plastic castings, is to captive joint between pipe link and the cutter link rod; The pipe link of prior art has decorative pattern or screw thread with the position that door cutter link rod is connected, and its purpose is to increase snap-in force.Because a door cutter link rod is a Plastic Parts, uses very easily wearing and tearing for a long time, thereby cause pipe link loosening even come off with a door cutter link rod.
Summary of the invention
The purpose of this invention is to provide a kind of elevator door knife system that has novel link rod, it can not cause pipe link and link rod to come off in long-time use, sound construction, and working stability is reliable.
In order to solve the existing problem of background technology; The present invention adopts following technical scheme: a kind of elevator door knife system that has novel link rod; It comprises first arc plate, second arc plate, base plate, first link rod, second link rod; Said first link rod comprises link rod body and pipe link, and the position that is connected with the link rod body on the said pipe link is provided with groove, and said pipe link and link rod body are the foundry goods that is connected as a single entity.
The present invention has with beneficial effect: the position that is connected with link rod at pipe link is provided with groove, increases the area of contact of pipe link and link rod, in long-time use, can not cause pipe link and link rod to come off, and working stability is reliable; Take extrusion process, pipe link and link rod body are connected as a single entity, and sound construction improves safety.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the birds-eye view of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2; This specific embodiment adopts following technical scheme: a kind of elevator door knife system that has novel link rod; It comprises first arc plate, second arc plate, base plate, first link rod, second link rod; Said first link rod comprises link rod body 1 and pipe link 2, and the position that is connected with link rod body 1 on the said pipe link 2 is provided with groove 3, said pipe link 2 and the foundry goods of link rod body 1 for being connected as a single entity.
With reference to Fig. 1, Fig. 2, this specific embodiment is taked extrusion process through being provided with groove at the position that is connected with link rod at pipe link, increases the area of contact of pipe link and link rod, and sound construction improves safety.
Explanation is at last; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Other modifications that those of ordinary skills make technical scheme of the present invention perhaps are equal to replacement; Only otherwise break away from the spirit and the scope of technical scheme of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
