A fan-shaped door mechanism and its application driving mechanism

Abstract

The invention discloses a fan-shaped door mechanism and its driving mechanism. The fan-shaped door mechanism has a base, a fan-shaped door arranged on the base, a gear assembly and a fan-shaped door connecting rod assembly. The fan-shaped door includes an outer door, an inner door and connecting Assemblies, the inner door is movably nested with the outer door through the connecting assembly; the gear assembly includes the upper gear, the lower gear and the upper gear connection assembly, the upper gear is movably connected with the outer door through the upper gear connection assembly, and the upper gear and the lower gear are connected to each other. meshing; one end of the fan-shaped door connecting rod is connected with the upper gear, and the other end is connected with the inner leaf door, and the inner leaf door enters and exits in the outer leaf door under the action of the fan-shaped door connecting rod assembly. The invention has simple structure, easy assembly, high production efficiency, does not occupy space other than the swing rod, improves the overall aesthetics of the gate unit, and enables the movement to be used in various gates; maintains the structure of the swing rod root It is not damaged, which ensures the stability of the important part of the movement structure - the swing rod.

Description

technical field [0001] The invention relates to the technical field of a gate for a rail transit automatic ticketing system, in particular to a fan-shaped door mechanism and its applied driving mechanism and gate. Background technique [0002] In the application of gates in rail transit (subway, railway, etc.) automatic fare collection systems, in order to install the gate mechanism that can effectively block wider passages in the narrow gate body, the industry generally adopts the design of the gate mechanism into the practice of telescopic doors. The current retractable inner door drive mechanism, one of which is the Chinese patent application No. 200710047469.0, which discloses a wide channel scissor door device for self-supporting ticket checking machines. At the same time, the lower gear, the upper gear and the linkage mechanism to promote the inner door. The advantage of such design is, the stability of leaf door swing bar is good, and the volume of the upper gear th...

AI Technical Summary

Problems solved by technology

The disadvantages are: the upper and lower gears need to occupy space outside the swing rod of the door, which is not conducive to the closeness of the left and right doors in the gate to the center line; the mechanism for the transmission of the upper gear to the inner door is complicated to assemble, which is not conducive to repair and maintenance; the inner and outer doors must be It can only be integrated when it is assembled to the door swing rod, which increases the workload and difficulty of assembly

[0003] Another Chinese patent with application number 200620040707.6 discloses a fan door mechanism in a fan door gate machine. The middle of the door swing rod saves the space other than the swing rod, but there are some problems in this design. First, because it adopts the working principle of planetary gear, the rotation of the inner door is fixed and limited by the gear, which makes it resistant to external The ability to impact is greatly reduced; secondly, the sun gear fixed on the base cuts off the swing rod of the door, which greatly weakens the strength and rigidity of the root of the swing rod, which directly affects the stability of the structure; thirdly, due to the planetary gear The structure of the system is relatively complex and there are many parts, resulting in high precision requirements for parts, heavy assembly workload and high requirements for production and maintenance.
