Technical Field

The invention relates to the technical field of elevators, in particular to a novel universal door leg structure of an elevator door system.

Background

The elevator door system comprises car doors and landing doors, one elevator comprises at least one car door system and several landing door systems, more and more high-rise buildings are built at present, the number of the landing doors is increased accordingly, the current landing door system has the problem of inconvenient installation, the installation convenience is greatly influenced due to the installation and processing problems of the door plates and the sills of door legs, and hidden dangers are left for the operation of subsequent elevators.

The direction of door system lower part all adopts door foot and sill subassembly cooperation horizontal direction in present elevator market, like figure 1 and figure 2, door foot 2 is assembled on door plant 1, during the switch door, door foot 2 horizontal slip in sill subassembly 3, because door foot 2 and sill subassembly 3 fit clearance are less than 0.5mm, if meet door plant 1 skew in the 2 installation of door foot, door plant 1 installation out of plumb, sill subassembly 3 installation skew, sill subassembly 3 processing straightness accuracy is not conform to the scheduling problem of requirement, all can influence normal switch door, cause power and noise increase, cause the door system operation card to hinder even. The doorleg structure on the market at present is not convenient to install and adjust as shown in figure 3, and has higher requirement on the processing precision of the sill.

Disclosure of Invention

The invention aims to provide a novel universal door leg structure of an elevator door system aiming at the technical problems of the matching structure between the existing door leg and a sill component, so as to improve the convenience of the installation of the door system, reduce the requirements of the door leg on the processing precision of the sill and the installation of the door system.

In order to achieve the purpose of the invention, the technical scheme adopted by the invention is as follows:

the universal door foot structure of the elevator door system comprises a door foot body and a door foot sliding block, wherein the door foot sliding block is arranged in a floor groove of the sill assembly in a sliding mode, the upper portion of the door foot body is connected with a door plate, and the lower portion of the door foot body is installed in the door foot sliding block in a rotatable mode.

In a preferred embodiment of the present invention, a lower portion of the door foot body is rotatably installed in the door foot slider in a direction perpendicular to the door panel.

In a preferred embodiment of the invention, the lower part of the gate leg body is provided with a gate leg ball, the middle upper part of the gate leg body is provided with a gate leg rod, the gate leg rod is connected with the gate leg ball, and the gate leg ball is accommodated in a ball pocket in the gate leg sliding block; the gate leg rod extends out of a gate leg rod outlet on the ball pocket.

In a preferred embodiment of the present invention, two limiting blocks are disposed on two sides of the door leg body parallel to the door panel direction, and the two limiting blocks are used for limiting the door leg body to rotate in the direction parallel to the door panel direction.

Due to the adoption of the technical scheme, the door foot body and the door foot sliding block in the universal door foot structure of the elevator door system are connected in a spherical manner, and when the door plate of the elevator door system has the problems of skew and non-vertical installation, the sill has the problems of installation inclination and poor processing straightness, the door foot body can rotate in a spherical manner, and the door foot sliding block and the sill groove can still be ensured to be parallel and run smoothly.

The invention can ensure that the safe operation of the elevator is still ensured when the door plate of the elevator door system has the problems of skew and non-vertical installation, the installation tilt of the sill and poor processing straightness.

Detailed Description

The invention is further described below in conjunction with the appended drawings and detailed description.

Referring to fig. 4 to 6, the universal door foot structure of the elevator door system shown in the drawings includes a foot body 100 and a foot slider 200.

The lower part of the gate leg body 100 is a gate leg ball 110, the middle upper part of the gate leg body 100 is a gate leg rod 120, and the gate leg rod 120 is fixedly connected with the gate leg ball 110. Or may be an integrally formed structure.

The doorleg sliding block 200 is slidably disposed in the sill groove 310 of the sill assembly 300, the upper portion of the doorleg rod 120 of the doorleg body 100 is connected to a door panel (not shown), and the doorleg ball 110 at the lower portion of the doorleg body 100 is rotatably mounted in the ball pocket 210 of the doorleg sliding block 200. The gate leg bar 120 extends from a gate leg bar outlet 211 of the ball pocket 210.

Stoppers 131 and 132 are disposed on both sides of the door leg body 100 parallel to the door panel direction, and the stoppers 131 and 132 are used to restrict the door leg body 100 from rotating in the direction parallel to the door panel direction (arrow a direction in fig. 4) but only in the direction perpendicular to the door panel direction (arrow B direction in fig. 5 and arrow C direction in fig. 6).

Referring to fig. 7 and 8, when the doorsill assembly 300 or the door panel 400 is inclined, the rotation direction of the doorleg body 100 is consistent with the inclination angle of the doorsill assembly 300 or the door panel 400, so as to meet the requirement of opening the door of the door panel; when the door panel 400 is not perpendicular to the sill component 300, the door foot sliding block 200 automatically tilts to ensure that the door foot sliding block 200 slides in cooperation with the sill component 300, so that the door opening requirement of the door panel is met.
