Especially in recent years, the subway construction in large and medium-sized cities in China has developed rapidly. At present, there are more than twenty cities in China that are building or expanding subway projects. At the position of the urban rail transit platform, in order to ensure the safety of passengers, a platform screen door system is usually installed beside the platform close to the subway track to separate the waiting platform from the track. A threshold is arranged below the platform screen door, and a guiding groove is arranged in the middle of the threshold, and the guiding groove can play a guiding role for the platform screen door.

[0003] An aluminum alloy subway platform screen door threshold disclosed in a Chinese utility model (publication number: CN221251149U) includes a front threshold and a rear threshold. A connecting structure is arranged between the front threshold and the rear threshold, and the connecting structure is recessed downward to form a guiding groove. A plurality of concave and convex grooves are arranged on the surfaces of the front threshold and the rear threshold. Through the arranged concave and convex groove structure, the threshold has an anti-slip function.

[0004] In the process of implementing the present utility model, the inventor found that there are at least the following problems in this technology: the anti-slip structure formed by the concave and convex grooves on the surface of the threshold will be gradually worn smooth during long-term trampling, resulting in a reduction in the anti-slip effect. In order to meet the anti-slip effect, the entire threshold needs to be disassembled and replaced, which is rather inconvenient. Therefore, a threshold structure of a subway platform screen door is now proposed. Content of the Utility Model

[0005] In order to improve the problem that the anti-slip structure formed by the concave and convex grooves on the surface of the existing threshold will be gradually worn smooth during long-term trampling, resulting in a reduction in the anti-slip effect, and in order to meet the anti-slip effect, the entire threshold needs to be disassembled and replaced, which is rather inconvenient, the present utility model provides a threshold structure of a subway platform screen door.

[0032] The following further Figures 1-4 describes the present application in detail.

[0033] Please refer to Figures 1-3, A threshold structure for a subway platform screen door, including a threshold body 1. A guide groove 2 for connecting with the guide shoes of the screen door is provided in the middle of the threshold body 1. Anti-slip plates 3 are installed on both sides of the surface of the threshold body 1 where the guide groove 2 is located. On one side of the two anti-slip plates 3 close to each other, a shielding soft hair 15 is installed, and the shielding soft hair 15 is located inside the guide groove 2. Through the setting of the shielding soft hair 15 structure on the two anti-slip plates 3, a shielding structure is formed at the guide groove 2, making it not easy for external sundries (such as paper scraps or plastic packages, etc.) to fall into the inside of the guide groove 2, which is beneficial to the movement of the screen door guide shoes inside the guide groove 2. The surface of the anti-slip plate 3 is provided with anti-slip lines. At both ends of the surface of the threshold body 1 where the anti-slip plate 3 is located, connecting plates 4 are integrally connected. A detachable connection structure is provided between the connecting plate 4 and the anti-slip plate 3. Through the setting of the detachable anti-slip plate 3, when the anti-slip lines on the surface of the anti-slip plate 3 are worn flat by trampling, only the anti-slip plate 3 needs to be replaced, without disassembling and assembling the entire threshold body 1, which is relatively convenient.

[0034] Refer to Figures 1-3 , The detachable connection structure includes a slot 5 opened at both ends of the anti-slip plate 3, a plug board 6 slidably installed inside the connecting plate 4, and a driving mechanism installed inside the connecting plate 4 to drive the plug board 6 to move horizontally. The plug board 6 is inserted into the slot 5. By driving the plug board 6 to move horizontally through the driving mechanism, the plug board 6 is moved in and out of the slot 5, thereby realizing the disassembly and assembly of the anti-slip plate 3. A square groove 7 is opened on the surface of the connecting plate 4. The driving mechanism includes a screw rod 8 rotatably installed inside the square groove 7 and a runner 9 fixedly installed on the surface of one end of the screw rod 8. The screw rod 8 is threadedly connected with the plug board 6. A threaded groove is opened on one side of the plug board 6, and the screw rod 8 is threadedly connected inside the threaded groove. By rotating the runner 9, the screw rod 8 is driven to rotate, thereby realizing the horizontal movement of the plug board 6.

[0035] Refer to Figure 1 , Figure 3 And Figure 4 , A rubber plate 10 for shielding the screw rod 8 is installed at the top of the square groove 7. The rubber plate 10 has a certain bendability, and the rubber plate 10 shields and protects the driving structure. Connecting grooves 11 are opened on both sides of the square groove 7. At both ends of the rubber plate 10, plugs 12 are integrally connected. The plugs 12 are inserted into the connecting grooves 11. By bending the middle of the rubber plate 10 into an arch shape, the rubber plate 10 is located inside the square groove 7, and then the rubber plate 10 returns to its original position under its own elastic force, and the plugs 12 at both ends of the rubber plate 10 are inserted into the connecting grooves 11 to realize the installation of the rubber plate 10. There are gaps between both ends of the rubber plate 10 and the inner side wall of the square groove 7. With this structure, when disassembling the rubber plate 10, it is convenient to apply a force to the end of the rubber plate 10 to move the plug 12 out of the connecting groove 11.

[0036] Refer to Figures 2-4, a limiting strip 13 is integrally connected to the bottom of the rubber plate 10. A limiting groove 14 is formed on the surface of the insertion plate 6. The limiting strip 13 is inserted into the interior of the limiting groove 14. The arrangement of the limiting strip 13 and the limiting groove 14 is such that when the rubber plate 10 is installed inside the square groove 7, the limiting strip 13 is inserted into the interior of the limiting groove 14, which is conducive to limiting the insertion plate 6.

[0037] The implementation principle of the present utility model is as follows: When it is necessary to replace the worn anti-slip plate 3, the rubber plate 10 inside the square groove 7 is taken out. By rotating the rotating wheel 9, the screw rod 8 is driven to rotate, thereby realizing the horizontal movement of the insertion plate 6, so that the insertion plate 6 is moved out of the insertion slot 5, realizing the disassembly and assembly of the anti-slip plate 3. Compared with the prior art, in this application, only the anti-slip plate 3 needs to be replaced, and there is no need to disassemble and assemble the entire threshold body 1, which is relatively convenient. Moreover, through the arrangement of the shielding soft hair 15 structure on the two anti-slip plates 3, a shielding structure is formed at the guide groove 2, and it is not easy for external sundries (such as paper sheets or plastic packages, etc.) to fall into the interior of the guide groove 2, which is conducive to the movement of the shielding door guide shoe inside the guide groove 2.

[0038] The above are all the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
