Description

Technical Field

[0001] This utility model belongs to the field of subway platform screen door technology, specifically relating to a novel maintenance cover hinge structure. Background Technology

[0002] Subway platform screen doors, as a high-capacity passenger transport tool in various cities, bring convenience and speed to people and are highly valued worldwide. Therefore, a safe, efficient, and comfortable riding environment is essential for the effective operation of the subway. The maintenance covers for subway platform screen doors serve decorative purposes, provide electrical maintenance interfaces, and function as passenger guidance signs. Thus, subway platform screen door maintenance covers are also a crucial component of ensuring the safe operation of the subway.

[0003] Traditional subway platform screen door maintenance covers typically consist of hinges and a cover, with the hinge structure connected to the outer cover via bolts at the top. During maintenance, the cover is opened by rotating the hinges to access the internal structure. However, the traditional connection between the cover and hinges, solely via bolts at the top, can lead to bolt loosening and the cover potentially detaching after prolonged use. Therefore, the structure needs improvement to achieve better structural stability, maintainability, and ease of installation. Utility Model Content

[0004] The main purpose of this utility model is to provide a new type of maintenance cover hinge structure. The structure of the maintenance cover hinge has been optimized and improved. The hinge installation structure has been optimized so that the hinge can be directly inserted into the slot on the maintenance cover. The bottom structure of the hinge and the maintenance cover are also connected by bolts, so as to achieve good structural stability and maintainability.

[0005] To achieve the above objectives, this utility model provides a novel maintenance cover hinge structure. The novel maintenance cover hinge structure includes a hinge assembly, which consists of two first hinge plates and one second hinge plate. The first hinge plates are symmetrically installed at both ends of the first hinge plate. The first hinge plate and the second hinge plate are rotatably connected. The hinge assembly is installed inside the maintenance cover, and the first hinge plate matches the slot structure on the maintenance cover.

[0006] This utility model provides a novel hinge structure for a maintenance cover. The first hinge plate matches the slot structure on the maintenance cover. During installation, the hinge can be pre-positioned through the slot, eliminating the need for repeated calibration of the hinge position and significantly improving assembly efficiency. The hinge assembly is installed entirely inside the maintenance cover, avoiding the problems of dust accumulation and impact damage of traditional exposed hinges, thus extending its service life. This assembly structure also enables it to achieve good structural stability and maintainability.

[0007] In one possible implementation, the first hinge plate and the second hinge plate are rotatably connected via a hinge shaft. The connection between the first and second hinge plates via the hinge shaft clearly defines the axis of rotation, ensuring that the maintenance cover rotates around a fixed axis when opening and closing, preventing offset or jamming.

[0008] In one possible implementation, flange bearings are provided at both ends of the hinge shaft. The flange bearings reduce the frictional resistance between the hinge shaft and the hinge plate, making the opening and closing of the maintenance cover smoother, which is especially suitable for equipment that requires frequent maintenance.

[0009] In one possible implementation, the maintenance cover is provided with a slot located below the card slot.

[0010] In one possible implementation, the first hinge plate is fixed to the slot from below by an external hexagonal bolt. The external hexagonal bolt secures the first hinge plate through the slot, and works in conjunction with the limiting function of the slot. Attached Figure Description
