Description

Technical Field

[0001] The utility model relates to the technical field of automatic ticket checking machine accessories, in particular to an electromagnetic chuck assembly of a gate fan door module for rail transit. Background Art

[0002] An automatic ticket checking machine (abbreviated as AGM, commonly known as a gate) is a device in the AFC system of urban rail transit that inspects and processes tickets and allows or blocks passengers from entering or leaving the paid area. It is installed at the junction of the paid area and the non-paid area of the station. Urban rail transit in China has entered a stage of large-scale and rapid development, and the network scale of each city is constantly expanding. With the rise of ticket checking methods such as two-dimensional codes, bank cards, face recognition, and mobile phone NFC, the number of automatic ticket vending machines configured in the subways of each city has decreased, and at the same time, the performance requirements for automatic ticket checking machines are getting higher and higher. It is required not only to be accurate and fast when verifying codes and cards, but also to have zero failures during operation to ensure that there will be no passenger congestion.

[0003] However, according to statistics, the electromagnetic chuck failure of the gate fan door module accounts for 36% of the total gate failures and is also one of the main costs for the operation and maintenance of the subway AFC system. The reason is that the energy is relatively large when the crank arm of the gearbox connecting rod stops moving, and during the movement of the fan door, the cross-recessed head screw frequently moves within the suction cup fixing valve port, resulting in the loosening of the hexagon nut fixing the suction cup.

[0004] Therefore, we propose an electromagnetic chuck assembly of a gate fan door module for rail transit. Content of the Utility Model

[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides an electromagnetic chuck assembly of a gate fan door module for rail transit.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme. An electromagnetic chuck assembly of a gate fan door module for rail transit includes an electromagnetic chuck main body. A cross-recessed head screw is movably installed on the inner wall of the electromagnetic chuck main body. The lower end of the outer wall of the cross-recessed head screw is threadedly connected with a self-locking anti-loosening hexagon nut main body. A rubber washer is movably installed on the upper end of the inner wall of the self-locking anti-loosening hexagon nut main body. The electromagnetic chuck main body includes an electromagnetic chuck body. An embedded groove is formed in the middle of the top of the electromagnetic chuck body. The self-locking anti-loosening hexagon nut main body includes a self-locking anti-loosening hexagon nut body, and the inner wall of the self-locking anti-loosening hexagon nut body is threadedly connected with the lower end of the outer wall of the cross-recessed head screw.

[0007] Preferably, a first moving hole is formed in the middle of the bottom inner wall of the electromagnetic chuck body at the position of the embedded groove.

[0008] Preferably, a limit anti-rotation hexagon block is fixedly installed in the middle of the bottom of the electromagnetic chuck body at the position of the embedded groove.

[0009] Preferably, a second moving hole is formed at the bottom of the limiting and anti-rotating hexagonal block at the position of the first moving hole.
