[0002] Subway safety doors are installed at the edge of the platforms of stations along the line to separate the platform area from the train running area. The existing subway safety doors adopt a rigid closing method during the opening and closing process, so there is no buffer space after closing, and the passengers' clothes or accessories are difficult to pull out, which poses certain safety risks and is easy to cause damage to the safety doors, making it inconvenient to repair and replace.

[0003] The prior art has a publication number of CN214740886U, and the technical solution disclosed in the patent document is as follows: a subway safety shield door, which is convenient for driving the protective device to move, so that the protective device is opened and closed, the passengers are isolated, and the occurrence of safety hazards is reduced. A protective device is set, and a movable clamping plate is set on the side opposite to the protective door. During the clamping process, it has a certain buffering performance to avoid direct pinching of fingers and reduce the occurrence of safety accidents. A warning light is set. When a passenger pulls the door, an alarm is automatically sounded, which is convenient for the staff to deal with it in time, further reducing the occurrence of safety accidents and meeting the purpose of use needs.

[0004] The above patent squeezes the clamping plate under the action of the support spring, thereby reducing the damage caused by the passengers' hands being pinched. However, after closing, the shielding doors on both sides collide with each other, causing the shielding doors to be damaged due to the collision. In addition, the clamping plate is fixedly connected to the support spring, which makes it inconvenient to disassemble and replace the worn clamping plate. Utility Model Content

On both sides between the sliding door frame 1 and the sliding door frame 2, a safety door protection mechanism 3 is slidably installed. Above the inside of the sliding door frame 1, a mounting groove 11 is opened, and at both ends of the bottom side of the sliding door frame 1, sliding grooves 12 are opened. On the left and right sides above the sliding door frame 2, sliding grooves 21 are opened.

[0029] As Figure 2 and Figure 3As shown in the figure, the safety door protection mechanism 3 includes an opening and closing component 31. The opening and closing component 31 is installed inside the sliding door frame 1. At the bottom sides of both ends of the opening and closing component 31, safety door components 32 are bolted. On the opposite sides of the two safety door components 32, buffer protection components 33 are bolted. The opening and closing component 31 includes a bidirectional lead screw 311. The bidirectional lead screw 311 is arranged in the first installation groove 11. A motor 312 is arranged on one side of the bidirectional lead screw 311. Threaded nuts 313 are threadedly connected to the outer walls of the left and right ends of the bidirectional lead screw 311. Connecting rods 314 are fixedly connected to the bottom sides of the threaded nuts 313. Fixed columns 315 are fixedly connected below the connecting rods 314. The safety door component 32 includes a safety door 321. The safety door 321 and the fixed column 315 are both bolted. Mounting seats 322 are bolted to the left and right ends of the upper and lower sides of the safety door 321. Pulleys 323 are fixedly connected to the mounting seats 322. The upper pulleys 323 are both slidably connected to the first chute 12. The lower pulleys 323 are both slidably connected to the second chute 21. Reflective strips 324 are pasted on the peripheries of the safety door 321. Installation grooves 325 are formed on the opposite sides of the two safety door 321. By pasting reflective strips 324 on the edges of the safety door 321, the range of the safety door 321 can be warned to passengers, so that when the safety door 321 is closed, it can remind passengers whether there is enough time or space to drill into the subway car, thereby reducing the number of times passengers are clamped.

[0030] As Figure 4 and Figure 5 As shown in the figure, the buffer protection component 33 includes rubber strips 331. The rubber strips 331 are bolted inside the installation grooves 325. At the upper and lower ends of the installation grooves 325 and on the outer walls of the safety door 321, mounting plates 332 are bolted. Mounting cylinders 333 are fixedly connected to the outer surfaces of the mounting plates 332. Springs 334 are embedded inside the mounting cylinders 333. Buffer plates 335 are embedded on the other sides of the springs 334. Sponge pads 338 are fixedly connected to the outer ends of the buffer plates 335.

In addition, the provided buffer protection component 33 makes the sponge pads 338 on both sides contact first when the safety door 321 is closed. Through the extrusion deformation of the spring 334, the safety doors 321 on both sides can be buffered and protected, reducing the damage caused by the impact during closing. After closing, the rubber strips 331 on both sides contact. Due to their flexibility, the clothes or limbs of passengers being clamped can have a certain elastic space to be pulled out and are not easily damaged. In addition, the rubber strips are bolted inside the installation grooves 325, and the mounting plates 332 are bolted to the upper and lower sides of the safety door 321, so that they can be disassembled for replacement and repair. After replacement, the buffer protection effect is improved.

[0031] The utility model provides a subway safety door that is convenient for maintenance. The specific working principle is as follows: The control system starts the motor 312 to drive the bidirectional lead screw 311 to rotate, so that the lead screw nuts 313 on both sides move towards each other, and the pulleys 323 slide in the first chute 12 and the second chute 21, so that the safety doors 321 on both sides are closed, and the sponge pads 338 on both sides come into contact first. Through the extrusion deformation of the spring 334, the safety doors 321 on both sides can be buffered and protected. Then, the rubber strips 331 on both sides are squeezed and contacted. If a passenger enters in a hurry, the bright spring 324 can remind the passenger whether there is enough time and space to enter the subway interior. If a passenger is accidentally clamped by the rubber strip 331, since the rubber strip 331 is flexible, the clothes or limbs clamped by the passenger can have a certain elastic space to be pulled out, reducing injuries. Moreover, the buffer protection component 33 is disassembled by bolts, which is convenient for replacement and maintenance.
