Description

Technical Field

[0001] This utility model relates to the technical field of front sealing plate hangers, and in particular to a front sealing plate hanger for rail transit platform screen doors that prevents loosening. Background Technology

[0002] Platform screen doors in rail transit are important safety facilities installed at the edge of rail transit station platforms. They play many important roles. The upper part of the platform screen door system is equipped with a control system for controlling the opening and closing of the screen doors. A front sealing plate is usually installed on the outside of the control system to isolate the control system from the external environment and keep the control system in a protected state.

[0003] However, rail transit is constantly accompanied by vibrations, which can easily cause the front sealing plate brackets to loosen, leading to the front sealing plate shifting or even falling off. Furthermore, the normal operation of the platform screen doors depends on the tight cooperation of various components. Loose brackets will cause the front sealing plate to be unstable, interfering with the normal opening and closing of the platform screen doors. Therefore, we need to consider how to solve this problem. Utility Model Content

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-8A non-loosening front sealing plate hanger for rail transit platform screen doors includes a front sealing plate 1, with baffles 2 on both sides of the front sealing plate 1. A connector 3 is provided on one side wall of the front sealing plate 1, and the connector 3 is fixedly connected to the front sealing plate 1 by bolts 4. A fixing block 5 is threadedly connected to the bolt 4. Two mounting plates 6 are fixedly connected to one side wall of the fixing block 5. Threaded sleeves 7 are fixedly connected to the opposite sides of the two mounting plates 6. Threaded rods 8 are threadedly connected to the two threaded sleeves 7. Clamping plates 9 are fixedly connected to the opposite ends of the two threaded rods 8, and the two clamping plates 9 cooperate with each other. Both are arc-shaped, and rubber layers are provided on opposite sides of the two clamping plates 9. The opposite ends of the two threaded rods 8 pass through the corresponding mounting plates 6 and are fixedly connected with knobs. After the fixing block 5 is fitted onto the bolt 4, the corresponding threaded rod 8 can be rotated through the two knobs. With the cooperation of the two threaded sleeves 7, the two threaded rods 8 move with the two clamping plates 9 to clamp the bolt 4. In this way, the bolt 4 is clamped and fixed by the two clamping plates 9, which can prevent the fixing block 5 from turning back and causing the bolt 4 to loosen, thus improving the stability of the connection between the connector 3 and the front sealing plate 1.

[0026] In this connector 3, two fixed sleeves 10 are rotatably connected to both ends. Each fixed sleeve 10 contains a moving rod 11, and the other end of each moving rod 11 is fixedly connected to a mounting block 12. Two fixed plates 13 are fixedly connected to the side walls of the two baffles 2. Each fixed plate 13 has a groove 14, and each groove 14 contains two slidable sliding plates 15. A wedge block 16 is fixedly connected to the opposite side of every two mating sliding plates 15. The opposite sides of every two mating sliding plates 15 are elastically connected to the inner wall of the corresponding groove 14 via a first spring 17. The other ends of the two mutually cooperating sliding plates 15 extend to the outside and are fixedly connected to the limiting blocks 18. Each mounting block 12 has a limiting groove 19 on both sides that cooperates with the corresponding limiting block 18. By inserting the limiting block 18 into the limiting groove 19, the multiple mounting blocks 12 and multiple fixing plates 13 are fixedly connected. In this way, by fixing the front sealing plate 1 and the two baffles 2, the stability of the connection is further improved, and the situation of the hanging parts loosening and falling off accidentally is avoided. Each sliding groove 14 is provided with a stop bar 20, and each stop bar 20 cooperates with the two corresponding wedge blocks 16.

[0027] Each abutment 20 has one end extending to the outside and is fixedly connected to a pressure plate 21. Each pressure plate 21 is elastically connected to a corresponding fixed plate 13 via a second spring 22. Each fixed sleeve 10 has a movable groove 23 on one inner wall, and a slidable movable plate 24 is installed in each groove 23. One end of each movable plate 24 is fixedly connected to an insert block 25. Each movable rod 11 has multiple slots 26 on its side wall that mate with the corresponding insert blocks 25. By inserting the insert blocks 25 into different slots 26, the position of the movable rod 11 can be adjusted, thereby changing the length of the fixed sleeve 10. The length of the fixed sleeve 10 can be adjusted according to the actual situation to facilitate installation. The other side of each movable plate 24 is elastically connected to the inner wall of the corresponding movable slot 23 through the third spring 27. The other side of each movable plate 24 is fixedly connected to the pull rod 28. The other end of each pull rod 28 extends to the outside. Pulling the pull rod 28 causes the movable plate 24 to move, which in turn causes the insert block 25 to move. At this time, the third spring 27 is in a compressed state. The movable rod 11 can be moved without releasing the hand. Then, when the hand is released, under the elastic action of the third spring 27, the insert block 25 is inserted into the new slot 26, thus realizing the adjustment of the movable rod 11.

[0028] In this utility model, during use, the connecting piece 3 and the front sealing plate 1 are fixedly connected by the bolt 4. Then, the fixing block 5 is fitted onto the bolt 4. Next, the corresponding threaded rod 8 is rotated by the two knobs. With the cooperation of the two threaded sleeves 7, the two threaded rods 8 will move, thereby causing the corresponding clamping plate 9 to move until the two clamping plates 9 fix the bolt 4. This can prevent the fixing block 5 from reversing, realize the anti-loosening of the bolt 4, and improve the stability of the fixed connection between the connecting piece 3 and the front sealing plate 1.

[0029] Then, the pressure plate 21 can be pressed to compress the second spring 22. At this time, the abutment rod 20 moves and pushes the two wedge blocks 16 to move in opposite directions, thereby causing the two sliding plates 15 to move in opposite directions with the corresponding limiting blocks 18 and compress the corresponding first springs 17. Without releasing the hand, the mounting block 12 is moved to the corresponding position by rotating the fixing sleeve 10. Then, the hand is released. Under the elastic action of the second spring 22, the abutment rod 20 returns to its original position. Under the elastic action of the two first springs 17, the two sliding plates 15 move relative to each other with the corresponding wedge blocks 16, thereby causing the two limiting blocks 18 to be engaged in the corresponding limiting grooves 19. The above steps can be repeated to fix multiple mounting blocks 12. In this way, the front sealing plate 1 and the two baffles 2 can be fixedly connected by the connector 3, which further improves the stability of the connection and avoids the hanging parts from loosening and accidentally falling off.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
