[0002] The subway door slide rail is an important component of the subway door system. It is installed at the bottom of the door and works in conjunction with the roller swing arm device installed on the car body structure to provide the required guiding movement.

[0003] Chinese Patent Publication No. CN222391239U discloses a subway door sliding track, including a long strip base plate, side walls, and a limiting block. The side walls are vertically arranged along one edge of the long side of the base plate, and the limiting block is perpendicular to both the base plate and the side walls, with all three intersecting at the same vertex. The base plate, side walls, and limiting block are integrally formed. The limiting block has a transition arc surface tangent to the inner surface of the side walls. This utility model adopts an integral molding process, requiring only one casting step in the manufacturing process. It eliminates the need for cutting and welding sheet metal, effectively overcoming the yield problems caused by sheet metal deformation due to thermal cutting, melting of welding metal, and material shrinkage after condensation, which lead to excessive dimensional and positional tolerances. This improves product yield. The manufacturing process is highly efficient, effectively shortening the production period. In terms of personnel, only one casting worker is needed, making staffing relatively simple and management costs relatively low.

[0004] In the aforementioned prior art, multiple mounting holes are set on the sliding track, and screws can be passed through the mounting holes and screwed into the installation position of the subway door to achieve the connection and fixation of the sliding track. However, during installation and subsequent maintenance, a large number of screws need to be repeatedly disassembled and reassembled, which increases the maintenance time. In addition, the installation space of the sliding track is relatively narrow and the operating space is limited, which further increases the difficulty of maintenance. Therefore, a subway door sliding track is needed to meet people's needs. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-7 This utility model provides a technical solution: a subway door sliding track, including a subway door 100, an installation groove 101 inside the subway door 100, and a sliding track 102 inside the installation groove 101; a positioning structure is connected to the sliding track 102, a slide plate 300 is slidably installed on the sliding track 102, a sliding snap-fit ​​structure is installed on the slide plate 300, two fixing seats 400 are fixedly installed on one side of the slide plate 300, and a limit structure is connected to the two fixing seats 400; a fixing strip 500 is fixedly installed on the sliding track 102, and a reset structure is connected to the fixing strip 500. During installation, the sliding track 102 can be restricted in its position in the installation groove 101 by the positioning structure, and the snap-fit ​​structure can be used to prevent the sliding track 102 from loosening. The snap-fit ​​structure can be used in conjunction with the limit structure to strengthen the snap-fit ​​structure. The reset structure can provide assistance when disassembling the sliding track 102 so that the sliding track 102 can be removed from the positioning structure.

[0026] Furthermore, the positioning structure includes several positioning rods 200. A T-shaped chuck 202 is fixedly installed on one side of each positioning rod 200. One end of each positioning rod 200 is fixedly installed inside the mounting groove 101. The inner wall of the mounting groove 101 has a threaded groove that matches the positioning rod 200. Several positioning holes 201 are opened inside the sliding track 102. The positioning rod 200 is movably installed in the corresponding positioning hole 201. After adjusting the orientation of the sliding track 102, it is placed in the mounting groove 101. The position of the sliding track 102 is adjusted so that the positioning hole 201 is fitted onto the T-shaped chuck 202 and the positioning rod 200. Finally, the wider end of the positioning rod 200 is positioned in the positioning hole 201 for positioning.

[0027] Furthermore, the sliding snap-fit ​​structure includes a T-shaped slot 301, which is formed inside the slide plate 300. The T-shaped chuck 202 is movably installed in the T-shaped slot 301. The slide plate 300 has several connecting slots 302, which are connected to the T-shaped slot 301. The connecting slots 302 are adapted to the T-shaped chuck 202. During installation, the T-shaped chuck 202 will pass through the positioning hole 201 and the connecting slot 302 and enter the T-shaped slot 301. At this time, the slide plate 300 can be pushed, and the slide plate 300 will cause the connecting slot 302 to deviate from the positioning rod 200 and the T-shaped chuck 202, so that the T-shaped chuck 202 is snapped into the T-shaped slot 301, thereby preventing the slide rail 102 from detaching from the mounting groove 101.

[0028] Furthermore, the skateboard 300 has two T-shaped grooves 303 inside, and T-shaped bars 304 are slidably installed in both T-shaped grooves 303. Both T-shaped bars 304 are fixedly installed on the slide rail 102. When the skateboard 300 moves, it slides on the T-shaped bars 304 through the T-shaped grooves 303. The arrangement of the T-shaped grooves 303 and T-shaped bars 304 can limit the direction of movement of the skateboard 300 and prevent the skateboard 300 from becoming loose from the slide rail 102.

[0029] Furthermore, the limiting structure includes a half gear 401, which is rotatably mounted between two fixed seats 400. A limiting rack 402 is fixedly mounted on one side of the corresponding T-shaped strip 304. The limiting rack 402 is slidably mounted in the corresponding T-shaped groove 303. A lever 403 is fixedly mounted on the half gear 401. A limiting screw 404 is movably mounted inside the lever 403. A positioning screw hole 405 is opened inside the slide plate 300, and the limiting screw 404 is adapted to the positioning screw hole 405. The lever 403 is turned to rotate the half gear 401. When the half gear 401 rotates continuously, its teeth will mesh with the limiting rack 402, which will restrict the current position of the slide plate 300 and prevent it from slipping. The continuously rotating lever 403 can also drive the limiting screw 404 to flip. The limiting screw 404 can be screwed into the positioning screw hole 405 to fix the angle between the lever 403 and the half gear 401, which can prevent it from flipping back and improving the stability of the slide plate 300, thus completing the installation operation of the slide rail 102.

[0030] Example 2: As Figure 2-7 To facilitate the removal of the slide rail 102 for inspection or replacement, a reset structure is provided. The reset structure includes a guide rod 501, which is fixedly installed on one side of the fixing bar 500 and slidably installed inside the slide plate 300. A spring 502 is slidably sleeved on the guide rod 501, with both ends of the spring 502 fixedly installed between the slide plate 300 and the fixing bar 500, respectively. A guide groove 503 is provided inside the slide plate 300, and the guide rod 501 is slidably installed in the guide groove 503. By rotating the limiting screw 404 and unscrewing it from the positioning screw hole 405, the compressed spring 502 will push the slide plate 300 to slide and reset, causing the slide plate 300 to drive the connecting groove 302 to re-align with the T-shaped chuck 202 and the positioning hole 201. At this time, pulling down the slide rail 102 will disengage it from the T-shaped chuck 202 and the positioning rod 200, so that the slide rail 102 can be removed. The remaining features are the same as in Embodiment 1.

[0031] The working principle is as follows: Before installation, the spring 502 is in an uncompressed state, so that the connecting groove 302 on the slide plate 300 is connected to the positioning hole 201. Select the sliding track 102 that corresponds to the length of the mounting groove 101 to prevent the sliding track 102 from shaking in the mounting groove 101. During installation, after adjusting the orientation of the sliding track 102, place it in the mounting groove 101. Adjust the position of the sliding track 102 to fit the positioning hole 201 onto the T-shaped chuck 202 and the positioning rod 200. Finally, the wider end of the positioning rod 200 is located in the positioning hole 201, while the T-shaped chuck 202 passes through the positioning hole 201 and the connecting groove. 302 enters the T-shaped slot 301. At this time, the slide plate 300 can be pushed towards the fixing bar 500. The slide plate 300 will slide on the T-shaped bar 304 through the T-shaped slide groove 303. The T-shaped slide groove 303 and the T-shaped bar 304 restrict the movement direction of the slide plate 300 and prevent the slide plate 300 from becoming loose from the slide rail 102. The continuously moving slide plate 300 can slide on the guide rod 501 through the guide groove 503 and compress the spring 502. The slide plate 300 will also drive the connecting groove 302 to deviate from the positioning rod 200 and the T-shaped chuck 202, so that the T-shaped chuck 202 is engaged in the T-shaped slot 301. (Reference) Figure 5 In this state, the slide rail 102 can be prevented from detaching from the mounting slot 101. At this time, the lever 403 is manually turned so that the lever 403 drives the half gear 401 to rotate on the fixed seat 400. When the half gear 401 continues to rotate, its teeth will contact the limiting rack 402, so that the half gear 401 and the limiting rack 402 mesh. During the meshing process, the slide 300 will move a certain distance. Under the meshing of the half gear 401 and the limiting rack 402, the current position of the slide 300 can be restricted to prevent it from slipping. In addition, the continuously rotating lever 403 can drive the limiting screw 404 to rotate so that the limiting screw 404 corresponds to the positioning screw hole 405. At this time, the limiting screw 404 can be screwed into the positioning screw hole 405 to fix the angle between the lever 403 and the half gear 401, which can prevent it from rotating back and improving the stability of the slide 300. The installation operation of the slide rail 102 can then be completed.

[0032] When the slide rail 102 needs to be removed for inspection or replacement, you can reach into the mounting slot 101 to feel for the limiting screw 404. By rotating the limiting screw 404 and unscrewing it from the positioning screw hole 405, the angle restriction between the lever 403 and the half gear 401 can be released. At this time, the compressed spring 502 will push the slide plate 300 to slide back to its original position, so that the slide plate 300 drives the connecting slot 302 to align with the T-shaped chuck 202 and the positioning hole 201 again. At this time, the T-shaped chuck 202 is no longer restricted by the T-shaped slot 301 and the slide plate 300. Pulling down the slide rail 102 will cause the connecting slot 302 and the positioning hole 201 to disengage from the T-shaped chuck 202 and the positioning lever 200, and the slide rail 102 can be removed.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
