[0025] like Figures 1 to 4As shown, a protective frame between a subway screen door and a subway door comprises a movable door support 1 and a pair of screen doors 2 slidably arranged in the movable door support 1, a flap 7 is movably arranged at the bottom of the movable door support 1, a guide roller 11 is coaxially mounted on the flap 7, and the length of the flap 7 is less than the total length of the pair of screen doors 2; an L-shaped connecting rod 12 is arranged on the screen door 2, a guide slider 13 is arranged at the bottom of the L-shaped connecting rod 12, and a slide groove group is respectively opened on the guide roller 11, and the slide groove group comprises a first slide groove 14 and a second slide groove 15, the first slide groove 14 is close to one side of the flap 7, and the second slide groove 15 is a spiral inclined slide groove, the first slide groove 14 and the second slide groove 15 are connected to each other, and the guide slider 13 is slidably arranged inside the slide groove group. In the process of opening the shield door, the shield door moves to both sides and drives the guide slider to slide inside the first slide slot. When it moves to the second slide slot, it drives the guide roller with the second slide slot to rotate. The guide roller is connected with a flap, so that the flap can rotate and overlap on the subway entrance to form a slope for children and the elderly. The flap can be overlapped at any position by flipping, and does not need to be limited to the horizontal position, thereby reducing the construction cost and making it more practical.

[0026] like Figures 1 to 4 As shown, in a specific embodiment, the movable door support 1 is provided with a mounting groove 5, the size of the mounting groove 5 is adapted to the shielding door 2, the top and bottom of the mounting groove 5 are provided with guide rails 6, and the threshold of the movable door support 1 and the foundation of the subway station are on the same surface. The mounting groove 5 facilitates the installation of the shielding door 2 in the later stage and improves the aesthetics.

[0027] like Figures 1 to 4 As shown, the outer wall of the shielding door 2 is wrapped with a shielding door outer frame 3, the bottom and top of the shielding door outer frame 3 are both installed with an electric slide 4, the electric slide 4 is slidably connected with the guide rail 6, and the shielding door outer frame 3 is connected with the L-shaped connecting rod 12. The electric slide 4 is started, wherein the driving source inside the electric slide 4 drives the roller to rotate, the roller contacts the guide rail 6, and the electric slide 4 starts to move along the guide rail 6 through friction, and the shielding door outer frame 3 and the shielding door 2 are installed on the electric slide 4, so the shielding door 2 can move, thereby achieving the purpose of opening the shielding door 2.

[0028] like Figures 1 to 4As shown, further, a synchronous shaft 8 is installed at the rotation center of the flap 7, the synchronous shaft 8 and the guide roller 11 are connected to each other, and a bearing is sleeved on the outer wall of the end of the synchronous shaft 8, and a bearing seat 16 is clamped on the outer wall of the bearing, and the bearing seat 16 is mutually connected to the back of the moving door support 1. A fixed block 10 is movably sleeved on the outer wall of the synchronous shaft 8, and the fixed block 10 is fixedly connected to the back of the moving door support 1. A torsion spring 9 is sleeved on the synchronous shaft 8, one end of the torsion spring 9 is clamped on the side wall of the flap 7, and the other side is clamped on the fixed block 10. The guide roller 11 rotates, and then the guide roller 11 connects the synchronous shaft 8 and the flap 7 to rotate, which drives the flap 7 to open, and flips the flap 7 on the subway again, and during the rotation of the flap 7, the torsion spring 9 clamped on the surface is driven to twist, and the torsion spring 9 is used to facilitate the reset operation later.

[0029] The flap 7 is pasted with an anti-skid pad. Friction can be increased by the anti-skid pad to ensure that when the flap 7 is in an inclined state, the wheelchair can normally go up and down.

[0030] The implementation principle of the protective frame between a subway screen door and a subway door of this embodiment is as follows:

[0031] When the subway door needs to be opened, the shielding door needs to be opened first, and the electric slide 4 is started first. The driving source inside the electric slide 4 drives the roller to rotate, and the roller contacts the guide rail 6, and the electric slide 4 is driven by friction to start moving along the guide rail 6. The shielding door outer frame 3 and the shielding door 2 are installed on the electric slide 4, so the shielding door 2 can move, thereby achieving the purpose of opening the shielding door 2.

[0032] At the initial stage of movement of the shielding door 2, the L-shaped connecting rod 12 of the side wall starts to move synchronously, and the guide slider 13 on the L-shaped connecting rod 12 always moves along the first slide groove 14, and will not drive the guide roller 11 to rotate, ensuring that the flap 7 will not move when the shielding door 2 is not fully opened. When the guide slider moves to the second slide groove 15, the second slide groove 15 is in a spiral state, causing the second slide groove 15 and the guide roller 11 to rotate, and the guide roller 11 connecting the synchronization shaft 8 and the flap 7 rotates, thereby opening the flap 7. During the rotation of the flap 7, the torsion spring 9 clamped on the surface is driven to twist, and the torsion spring 9 is used to facilitate the subsequent reset operation.
