Abstract
The invention discloses an elevator door knife device with an elastic stretch assembly, relating to the field of elevator door knife devices. The elevator door knife device comprises a first circular arc plate, a second circular arc plate, a base plate, a first connecting rod, a second connecting rod and an elastic stretch assembly, wherein the elastic stretch assembly comprises a spiral spring formed by a spring wire as well as a first connecting member and a second connecting member which are respectively arranged at two ends of the spring; one end of the first connecting member is connected with the first connecting rod through a pin roll; the other end of the first connecting member is connected with the spring; one end of the second connecting member is connected with a jack post perpendicular to the base plate; and the other end of the second connecting member is connected with the spring. According to the elevator door knife device, the contacted area between the spring wire and the pin roll as well as the contacted area between the spring wire and the jack post can be increased; and under the condition that tensile forces are identical, the wear between the spring wire and the pin roll as well as the wear between the spring wire and the jack post are reduced and the service life of the spring wire is prolonged.
Description
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 the elastic stretching assembly.
Background technology
At present; The general elastic stretching assembly that adopts stretches in the elevator door knife system, and easy for installation because of the elastic stretching assembly, and spring wire is a round wire; Directly link to each other with bearing pin, the jack-post of circle; But because area of contact is little, thereby in use be prone to cause steel wire, bearing pin, jack-post wearing and tearing, cause spring wire to break off.
Summary of the invention
The purpose of this invention is to provide a kind of elevator door knife system that has the elastic stretching assembly; It can increase spring wire and bearing pin, the jack-post area that is connected; Under the identical situation of pulling force, reduced the wearing and tearing of spring wire and bearing pin, jack-post, prolonged the service life of spring wire.
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 the elastic stretching assembly; It comprises first arc plate, second arc plate, base plate, first link rod, second link rod and elastic stretching assembly; Said elastic stretching assembly comprises the spiral spring of spring wire composition, first attaching parts and second attaching parts of said both ends of the spring; One end of said first attaching parts links to each other with said first link rod through bearing pin; The other end of said first attaching parts is connected with said spring, an end of said second attaching parts with link to each other perpendicular to the jack-post on the said base plate, the other end of said second attaching parts is connected with said spring.
As improvement, said first attaching parts end that is connected with said spring is provided with two columniform circular holes, and a hole penetrates a spring wire, and an other hole penetrates two spring wires; Said second attaching parts end that is connected with said spring is provided with two columniform circular holes, and a hole penetrates a spring wire, and an other hole penetrates two spring wires.
The present invention has following beneficial effect: spring links to each other with attaching parts; Attaching parts links to each other with bearing pin, jack-post, is that face contacts between attaching parts and bearing pin, the jack-post, increases the area of contact that bearing pin, jack-post link to each other; Reduce the wearing and tearing of spring wire and bearing pin, jack-post, prolonged the service life of spring wire; Adopt double-pore structure, under the identical situation of pulling force, make spring wire reduce half, thereby in use can not produce the open circuited phenomenon of spring wire the pressure of attaching parts, safe and reliable.

Fig. 1 is a structural representation of the present invention.
Fig. 2 is first, second attaching parts and spring bonded assembly scheme drawing among the present invention.
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 the elastic stretching assembly; It comprises first arc plate, second arc plate, base plate, first link rod, second link rod and elastic stretching assembly; Said elastic stretching assembly comprises the spiral spring 1 of spring wire composition, first attaching parts 2 and second attaching parts 3 of said both ends of the spring; One end of said first attaching parts 2 links to each other with said first link rod 4 through bearing pin; The other end of said first attaching parts 2 is connected with said spring 1, an end of said second attaching parts 3 with link to each other perpendicular to the jack-post 6 on the said base plate 5, the other end of said second attaching parts 3 is connected with said spring 1.
With reference to Fig. 2, said first attaching parts 2 end that is connected with said spring 1 is provided with 7, one holes of two columniform circular holes and penetrates a spring wire, and an other hole penetrates two spring wires; Said second attaching parts 3 end that is connected with said spring 1 is provided with 7, one holes of two columniform circular holes and penetrates a spring wire, and an other hole penetrates two spring wires.
This specific embodiment adopts double-pore structure, under the identical situation of pulling force, makes the pressure of spring wire reduce half, thereby in use can not produce the open circuited phenomenon of spring wire, and is safe and reliable.
