Abstract
The invention discloses an elevator door knife assembly and relates to the field of elevator car door knife assemblies. The elevator door knife assembly comprises a first circular arc plate, a second circular arc plate, a base plate, a first connecting rod and a second connecting rod, wherein the first circular arc plate, the first connecting rod, the second circular arc plate and the second connecting rod sequentially pass through shaft pins to form a four-link mechanism; the base plate is in shaft connection with the first connecting rod and the second connecting rod; the first connecting rod is connected with a bottom bar through a spring; and a limiting device is arranged between the base plate and the first connecting rod. The elevator door knife assembly disclosed by the invention has the advantages of reasonable design, simple structure, dependence on a spring stretching and limiting device, safety and reliability in work, low cost and prevention of potential safety hazards.
Description
Technical field
The present invention relates to elevator cage door knife assembly field, be specifically related to a kind of elevator door knife assembly.
Background technology
Along with increasing of modern floor, the use of elevator brings great convenience to people.But the safety problem of elevator also becomes the problem that people pay special attention to.In order to guarantee personal safety, be at the sedan-chair case and allow to open the sedan-chair chamber door when aspect is opened the door the zone, and in non-layer Men Kaimen zone, the sedan-chair chamber door should lock, and prevents that people from opening the sedan-chair chamber door in the sedan-chair case.In order to guarantee personal safety, generally guarantee when opening the sedan-chair chamber door, to be unlikely to cause danger, but this method exists the cost height, the defective that the construction period is long in the prior art through in hoistway, installing the protection wire netting additional.
Summary of the invention
The purpose of this invention is to provide a kind of elevator door knife assembly, it is reasonable in design, and is simple in structure, relies on springs and inhibiting device, and safe and reliable, cost is low, avoids potential safety hazard.
In order to solve the existing problem of background technology; The present invention adopts following technical scheme: a kind of elevator door knife assembly; It comprises first arc plate, second arc plate, base plate, first link rod and second link rod; Form four-bar linkage through pivot pin successively between said first arc plate, first link rod, second arc plate, second link rod; And said base plate is connected with first link rod, the second link rod axle, and said first link rod links to each other through spring with bottom bar, is provided with inhibiting device between the said base plate and first link rod.
The present invention has following beneficial effect: reasonable in design, simple in structure, and rely on spring opposite house knife assembly to stretch, reliability height and cost are low; Adopt inhibiting device, avoid spring excessively to stretch, simple and convenient, improve safety.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
With reference to Fig. 1; This specific embodiment adopts following technical scheme: a kind of elevator door knife assembly; It comprises first arc plate 1, second arc plate 2, base plate 3, first link rod 4 and second link rod 5; Form four-bar linkage through pivot pin successively between said first arc plate 1, first link rod 4, second arc plate 2, second link rod 5; And said base plate 3 is connected with first link rod 4,5 of second link rods, and said first link rod 4 links to each other through spring 6 with bottom bar 3, is provided with inhibiting device 7 between the said base plate 3 and first link rod 4.
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.
