Abstract
The utility model discloses an elevator door knife device with an elastic stretch component, and relates to the field of elevator door knife devices. The elevator door knife device with the elastic stretch component comprises a first arc plate, a second arc plate, a bottom plate, a fist joining beam, a second joining beam and an elastic stretch component. The elastic stretch component comprises a spiral spring composed of spring wires, a first connecting piece and a second connecting piece both arranged at two ends of the spring, one end of the first connecting piece is connected with the first joining beam through a pin shaft, the other end of the first connecting piece is connected with the spring, one end of the second connecting piece is connected with a shaft post perpendicular to the bottom plate, and the other end of the second connecting piece is connected with the spring. The elevator door knife device with the elastic stretch component can increase the connecting and contacting areas between the spring wires and the pin shaft and between the spring wires and the shaft post, and under the condition that tensile forces are identical, the abrasion between the spring wires and the pin shaft and between the spring wires and the shaft post is reduced, and the service life of the spring wires is prolonged.
Description
Technical field
The utility model relates to the elevator door vane device field, is specifically related to a kind of elevator door vane device with the elastic stretching assembly.
Background technology
At present, the general elastic stretching assembly that adopts stretches in the elevator door vane device, because of the elastic stretching assembly easy for installation, and spring wire is 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 easily cause steel wire, bearing pin, jack-post wearing and tearing, cause spring wire to disconnect.
Summary of the invention
The purpose of this utility model provides a kind of elevator door vane device with the elastic stretching assembly, it can increase spring wire and bearing pin, the jack-post area that is connected, in the situation that pulling force is identical, 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 utility model is by the following technical solutions: a kind of elevator door vane device with the elastic stretching assembly, it comprises the first arc plate, the second arc plate, base plate, the first link rod, the second link rod and elastic stretching assembly, described elastic stretching assembly comprises the spiral spring that spring wire forms, the first attaching parts of described both ends of the spring and the second attaching parts, one end of described the first attaching parts links to each other with described the first link rod by bearing pin, the other end of described the first attaching parts is connected with described spring, one end of described the second attaching parts with link to each other perpendicular to the jack-post on the described base plate, the other end of described the second attaching parts is connected with described spring.
As improvement, described the first attaching parts end that is connected with described spring is provided with two columniform circular holes, and a hole penetrates a spring wire, and an other hole penetrates two spring wires; Described the second attaching parts end that is connected with described spring is provided with two columniform circular holes, and a hole penetrates a spring wire, and an other hole penetrates two spring wires.
The utlity model has following beneficial effect: spring links to each other with attaching parts, attaching parts links to each other with bearing pin, jack-post, that face contacts between attaching parts and bearing pin, the jack-post, increase bearing pin, the continuous area of contact of jack-post, reduce the wearing and tearing of spring wire and bearing pin, jack-post, prolonged the service life of spring wire; Adopt double-pore structure, in the situation that pulling force is identical so that spring wire to the pressure decreased of attaching parts half, thereby in use can not produce the phenomenon that spring wire disconnects, safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram that first, second attaching parts is connected with spring in the utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, this specific embodiment is by the following technical solutions: a kind of elevator door vane device with the elastic stretching assembly, it comprises the first arc plate, the second arc plate, base plate, the first link rod, the second link rod and elastic stretching assembly, described elastic stretching assembly comprises the spiral spring 1 that spring wire forms, the first attaching parts 2 of described both ends of the spring and the second attaching parts 3, one end of described the first attaching parts 2 links to each other with described the first link rod 4 by bearing pin, the other end of described the first attaching parts 2 is connected with described spring 1, one end of described the second attaching parts 3 with link to each other perpendicular to the jack-post 6 on the described base plate 5, the other end of described the second attaching parts 3 is connected with described spring 1.
With reference to Fig. 2, described the first attaching parts 2 end that is connected with described 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; Described the second attaching parts 3 end that is connected with described 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, in the situation that pulling force is identical so that the pressure decreased of spring wire half, thereby in use can not produce the phenomenon that spring wire disconnects, safe and reliable.
