Technical Field

[0001] This utility model relates to the field of subway escape ladder technology, specifically a subway escape ladder. Background Technology

[0002] Subway escape stairs are important devices used for passenger evacuation in subway trains during emergencies. Their design and function are crucial to ensuring passenger safety. They are generally installed at the bottom of subway train cars or directly below passenger compartment doors.

[0003] Existing subway escape ladders have a simple structure, making them inconvenient to quickly extend according to specific situations and difficult to erect when not against a wall, thus limiting their applicability. Therefore, a new type of subway escape ladder needs to be designed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a subway escape ladder to solve the problems raised by the background technology.

[0005] To achieve the purpose of ascending, the present invention provides the following technical solution: a subway escape ladder, including a first side plate, two first side plates are provided, a first climbing rod is fixedly installed between the two first side plates, and a plurality of first climbing rods are provided, a first sliding groove is opened on the surface of the first side plate, and a first slider is slidably connected inside the first sliding groove;

[0006] The surface of the first slider is rotatably connected to a second side plate via a bracket. A second climbing rod is fixedly connected between the two second side plates, and several second climbing rods are provided. A limit mechanism is provided on one side of the first side plate.

[0007] Preferably, the limiting mechanism includes a second slide groove formed on one side of the first side plate, a second slider slidably connected to the surface of the second slide groove, an arc-shaped slide plate fixedly installed on one side of the second slider, a slide rod slidably connected inside the arc-shaped slide plate, and one end of the slide rod fixedly connected to one side of the second side plate.

[0008] Preferably, a bidirectional threaded rod is rotatably connected above the two first side plates via a bearing component. Both sides of the surface of the bidirectional threaded rod are threaded with threaded sleeves. A traction plate is fixedly installed on the surface of the threaded sleeves, and a J-shaped rod is fixedly installed on one side of the traction plate.

[0009] Preferably, a U-shaped plate is fixedly installed at the rear of the first side plate.

[0010] Preferably, a third slider is slidably connected to both sides inside the U-shaped plate.

[0011] Preferably, the surface of the third slider is fixedly connected to the rear of the threaded sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This subway escape ladder, by rotating a bidirectional threaded rod, causes two threaded sleeves to move to both sides. The movement of the threaded sleeves causes the J-shaped rod to move, and after the J-shaped rod moves, it pushes the second side plate upward. The rise of the second side plate causes the arc-shaped slide plate to rise. After the arc-shaped slide plate rises, the bidirectional threaded rod rotates in the opposite direction. At this time, the bidirectional threaded rod causes the two J-shaped rods to move to the middle simultaneously. After the J-shaped rod moves, it can limit the arc-shaped slide plate, thereby achieving the effect of limiting and fixing the second side plate after it rises, which improves the applicability of the device. Furthermore, by tightly attaching the surface of the second side plate to the rear of the J-shaped rod, the second side plate can be stored and fixed.

[0014] 2. This subway escape ladder, by flipping the second side panel forward, can rotate the entire device half a turn, so that the first side panel can be supported on the ground by the second side panel, thereby facilitating the installation of the device on the ground without walls.

Detailed Implementation

[0021] 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.

[0022] Example 1

[0023] Please refer to Figure 1-5 As shown, this utility model provides a subway escape ladder, including a first side plate 1, two first side plates 1 are provided, a first climbing rod 2 is fixedly installed between the two first side plates 1, and a plurality of first climbing rods 2 are provided. A first sliding groove 3 is opened on the surface of the first side plate 1, and a first slider 4 is slidably connected inside the first sliding groove 3.

[0024] Specifically, the surface of the first slider 4 is rotatably connected to the second side plate 5 via a bracket. A second climbing rod 6 is fixedly connected between the two second side plates 5, and several second climbing rods 6 are provided. A limiting mechanism is provided on one side of the first side plate 1. The limiting mechanism includes a second slide groove 9 opened on one side of the first side plate 1. A second slider 10 is slidably connected to the surface of the second slide groove 9. An arc-shaped slide plate 7 is fixedly installed on one side of the second slider 10. A slide rod 8 is slidably connected inside the arc-shaped slide plate 7. One end of the slide rod 8 is fixedly connected to one side of the second side plate 5. By setting a traction mechanism and flipping the second side plate 5 forward, the device can be flipped half a turn as a whole after the second side plate 5 is flipped forward, so that the first side plate 1 can be supported on the ground by the second side plate 5, thereby achieving the effect of facilitating the installation of the device on the ground without walls.

[0025] Specifically, a bidirectional threaded rod 11 is rotatably connected above the two first side plates 1 via bearing components. Threaded sleeves 12 are threadedly connected to both sides of the surface of the bidirectional threaded rod 11. A traction plate 13 is fixedly mounted on the surface of the threaded sleeves 12. A J-shaped rod 14 is fixedly mounted on one side of the traction plate 13. A U-shaped plate 15 is fixedly mounted at the rear of the first side plate 1. Third sliders 16 are slidably connected to both sides inside the U-shaped plate 15. The surface of the third sliders 16 is fixedly connected to the rear of the threaded sleeves 12. By setting the bidirectional threaded rod 11 and rotating it, the bidirectional threaded rod 11 drives the two threaded sleeves 12 to move to both sides respectively. The movement of sleeve 12 drives the movement of J-shaped rod 14. After the movement of J-shaped rod 14, it pushes the second side plate 5 upward. The rise of the second side plate 5 drives the arc-shaped slide plate 7 to rise. After the arc-shaped slide plate 7 rises, it rotates the bidirectional threaded rod 11 in the opposite direction. At this time, the bidirectional threaded rod 11 drives the two J-shaped rods 14 to move towards the middle at the same time. After the movement of J-shaped rod 14, it can limit the arc-shaped slide plate 7, thereby achieving the effect of limiting and fixing the second side plate 5 after it rises. This effectively increases the length of the device and improves its applicability. Furthermore, by tightly attaching the surface of the second side plate 5 to the rear of the J-shaped rod 14, the second side plate 5 can be stored and fixed.

[0026] Working Principle: This utility model is a subway escape ladder. By rotating the bidirectional threaded rod 11, the bidirectional threaded rod 11 drives the two threaded sleeves 12 to move to both sides respectively. The movement of the threaded sleeves 12 drives the J-shaped rod 14 to move. After the J-shaped rod 14 moves, it no longer limits the second side plate 5. At this time, the second side plate 5 can be flipped forward. After the second side plate 5 is flipped forward, the entire device can be flipped half a turn, so that the first side plate 1 can be supported on the ground by the second side plate 5. This achieves the effect of facilitating the installation of the device on the ground without walls. When it is necessary to extend the device, the bidirectional threaded rod 11 can be rotated to drive the two threaded sleeves 12 to move to both sides respectively. The side movement of the threaded sleeve 12 causes the J-shaped rod 14 to move. After the J-shaped rod 14 moves, it pushes the second side plate 5 upward. The rise of the second side plate 5 causes the arc-shaped slide plate 7 to rise. After the arc-shaped slide plate 7 rises, it rotates the bidirectional threaded rod 11 in the opposite direction. At this time, the bidirectional threaded rod 11 drives the two J-shaped rods 14 to move towards the middle at the same time. After the J-shaped rod 14 moves, it can limit the arc-shaped slide plate 7, thereby achieving the effect of limiting and fixing the second side plate 5 after it rises. This effectively increases the length of the device and improves its applicability. Furthermore, by tightly attaching the surface of the second side plate 5 to the rear of the J-shaped rod 14, the second side plate 5 can be stored and fixed.
