[0002] In the subway transportation system of modern cities, platform screen doors play a crucial role. They not only ensure the safety of passengers but also optimize the ventilation and energy-saving effects of stations.

[0003] Traditional subway platform screen doors have certain limitations in design and installation. The connection structure between their frames and driving devices is relatively complex and difficult to disassemble. When maintenance or replacement of the driving device is required, it will consume a large amount of time and labor costs. Moreover, the glass door panels of traditional screen doors are mostly of an integral design. Once a certain part of them is damaged, the entire door panel needs to be replaced as a whole, which not only increases the maintenance cost but also causes waste of resources. For this reason, we propose a detachable subway platform screen door. Content of the Utility Model

[0021] Embodiment 1

[0022] Please refer to Figures 1-4 As shown, the utility model provides a detachable subway platform screen door, which includes a screen frame 1. A linear motor 2 is installed at the top of the screen frame 1. A moving plate 3 is installed at the moving end of the linear motor 2. A card slot 4 is formed on the surface of the moving plate 3. An installation frame 5 is slidably installed inside the card slot 4. The moving plate 3 and the installation frame 5 are detachably connected;

[0023] A door panel hole 6 is formed on the surface of the installation frame 5. A door panel installation groove 7 communicating with the door panel hole 6 is formed inside the installation frame 5. A plurality of door panels 9 are arranged inside the door panel installation groove 7. Adjacent two door panels 9 are in contact with each other. A sliding groove 10 is formed on one side of the installation frame 5. A blocking component for limiting the door panel 9 is installed inside the sliding groove 10.

[0024] Specifically, during maintenance, the entire installation frame 5 can be removed, or the blocking component can be controlled to not limit the door panel 9, so that the rotating support wheel 8 can be removed from the door panel installation groove 7 and the door panel hole 6, and then the damaged door panel 9 can be replaced separately.

[0025] Among them: The moving plate 3 and the installation frame 5 are fixed by bolts. Removing the bolts can slide the installation frame 5 out from the inside of the card slot 4 on the surface of the moving plate 3.

[0026] Among them: A plurality of rotating support wheels 8 are rotatably installed at the lower part inside the door panel installation groove 7. When the door panel 9 moves inside the door panel installation groove 7, the rotating support wheels 8 can rotate, so that the movement of the door panel 9 is smoother.

[0027] Among them: The blocking component includes an L-shaped block 11. The L-shaped block 11 is slidably installed inside the sliding groove 10. A threaded rod 12 is threadedly connected inside the L-shaped block 11. One end of the threaded rod 12 is rotatably installed on one side of the installation frame 5. The other end of the threaded rod 12 is fixedly installed with a knob 13. Rotating the knob 13 drives the threaded rod 12 to rotate, so that the L-shaped block 11 moves.

[0028] Among them: The thickness of the door panel 9 matches the width dimension of the door panel installation groove 7, and the door panel 9 can just pass through the door panel installation groove 7.

[0029] Working principle: The utility model is a detachable subway platform screen door. During use, the linear motor 2 is controlled to drive the moving plate 3 to move horizontally, so as to drive the two installation frames 5 to move horizontally, and the operations of opening and closing the door are carried out. When it is necessary to remove and maintain the installation frame 5 and the door panel 9 as a whole, only the bolts connecting the moving plate 3 and the installation frame 5 need to be removed, and the installation frame 5 can be removed by sliding the installation frame 5 out from the card slot 4 on the surface of the moving plate 3;

[0030] The door panel holes 6 are sealed by multiple door panels 9. When a single door panel 9 is damaged, only the damaged door panel 9 needs to be replaced. First, rotate the knob 13 to drive the threaded rod 12 to rotate, so that one side of the L-shaped stopper 11 disengages from the door panel mounting groove 7 and enters the sliding groove 10. The L-shaped stopper 11 does not block the door panel 9. Then, move the door panel 9 horizontally, so that the door panel 9 disengages from the door panel mounting groove 7 and the door panel hole 6, facilitating the individual replacement of the damaged door panel 9. When moving the door panel 9 horizontally, since the bottom of the door panel 9 contacts the rotating support wheel 8 and the rotating support wheel 8 can rotate, it is more labor-saving to move the door panel 9.

[0031] During installation, pass multiple door panels 9 through the door panel mounting groove 7 in sequence and move the door panel 9 horizontally to a suitable position, so that multiple door panels 9 can jointly block the door panel hole 6. Then, rotate the knob 13, so that one side of the L-shaped stopper 11 enters the door panel mounting groove 7 from the sliding groove 10 and blocks the door panel 9 at the edge position. Under the limit of the L-shaped stopper 11, multiple door panels 9 cannot move in the door panel mounting groove 7.
