Description

Technical Field

[0001] The utility model belongs to the technical field of subway underground passage decoration, in particular to a subway underground passage special-shaped plate decoration structure. Background Art

[0002] Subway, the full name of which is underground railway, is an urban rail transit system mainly used for underground operation. It plays a significant role in alleviating the pressure of ground traffic and improving the city's passenger transportation capacity. In the decoration process of subway underground passages, special-shaped panels are often used as the decoration panels. When installing special-shaped panels, connecting structures are also required.

[0003] In the Chinese utility model patent with publication number CN214144509U, a subway underground passage special-shaped plate decoration structure is disclosed. During installation, multiple mounting plates are snap-fitted through snap-fit ​​components. When the mounting plate is connected to the main beam, one side of the mounting plate is snapped into between two corresponding fixing blocks on the main beam, so that the mounting plate can be snap-fitted and connected to the main beam, thereby ensuring the stability of the mounting plate. At the same time, the snap-fitted mounting plate is easy to remove and install during maintenance or replacement.

[0004] After searching, it is found that the special-shaped plate decoration structure proposed in the above-mentioned comparative documents still has some defects and shortcomings in the actual operation process: the above-mentioned decoration structure adopts an elastic snap-fit ​​connection method, but the subway is built underground and is easily eroded by moisture. As the years increase, the spring is prone to rust and lose its elasticity, which will cause the special-shaped plate to loosen or even automatically detach, which poses certain risks. In addition, the pull ring is exposed and can be pulled by pedestrians, which is not safe enough. Therefore, it is urgent to improve the existing subway underground passage special-shaped plate decoration structure and provide a subway underground passage special-shaped plate decoration structure.

The upper and lower ends of the bidirectional screw rod are fixedly sleeved with limit blocks on the outer sides, and the two ends of the bidirectional screw rod are threadedly sleeved with movable blocks on the outer sides at opposite ends of the threads. A vertical rod is provided directly behind the bidirectional screw rod, and the upper and lower ends of the vertical rod are respectively fixedly connected to the first main beam and the second main beam.

[0011] As a preferred implementation, the cross section of the movable block is a "convex"-shaped structure, the sliding directions of the two movable blocks are always opposite, and the movable block is slidably connected to the vertical rod.

[0012] As a preferred embodiment, the limit slot assembly includes a through slot, a plug-in slot and a positioning slot. The through slot is opened on the outer wall directly behind the first special-shaped mounting plate, plug-in slots are opened on the inner walls at both ends of the through slot, and positioning slots are opened in the middle of the two plug-in slots.
