DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0019] As shown in Figures 1-4 A multifunctional subway platform shielding door, comprising a fixed door 1, a display screen 2 is arranged at the upper end position of the fixed door 1, a movable door structure 3 is arranged on the fixed door 1, an observation port is arranged on the fixed door 1, and an isolation glass 4 is fixed in the observation port of the fixed door 1, an indicator light 5 is installed on the top of the fixed door 1, and the indicator light 5 is symmetrically arranged on the fixed door 1.

[0020] When the shielding door is used, the fixed door 1 is installed on the subway platform, and the movable door structure 3 is installed on the fixed door 1, and the display screen 2 and the indicator light 5 on the fixed door 1 are connected to the subway system. When the movable door structure 3 is opened and closed, the indicator light 5 flashes to remind the passengers, and the internal driving structure of the fixed door 1 drives the movable door structure 3 to open or close. During this process, the isolation glass 4 not only plays a role of isolation, but also facilitates passengers to directly observe the subway. In the process of waiting for the subway, passengers can understand the subway arrival situation in real time through the display screen 2, and make preparations in advance. If the passenger passes through the movable door structure 3 before it is completely opened due to impatience, the passenger's feet are easy to collide with the movable door structure 3, at this time, the bottom component in the movable door structure 3 can play a role of buffering and anti-collision, protecting the passenger's soles, and ensuring the integrity of the movable door structure 3.

[0021] Through the above-mentioned embodiment, the movable door structure 3 comprises a door body 301, a buffer assembly 303 and a tempered glass 304, the upper end of the door body 301 is provided with a square hole, and the lower end of the door body 301 is provided with a buffer hole, the buffer assembly 303 is installed in the buffer hole at the lower end of the door body 301, and the tempered glass 304 is fixed in the square hole at the upper end of the door body 301. The movable door structure 3 further comprises a rubber strip 302 and a mounting back plate 305, the rubber strip 302 is fixed on one side of the door body 301, the mounting back plate 305 is installed in the buffer hole at the lower end of the door body 301, and the mounting back plate 305 is connected with the buffer assembly 303.

[0022] The buffer assembly 303 comprises a buffer frame 3031, a cover plate 3032, a square groove 3033, a protective roller 3034, a counterbore 3035, a guide connecting rod 3036, a limiting block 3037 and a buffer spring 3038. The cover plate 3032 is fixed at the upper end of the buffer frame 3031, the square groove 3033 is arranged on the buffer frame 3031, the protective roller 3034 is rotatably arranged in the square groove 3033 on the buffer frame 3031, and the upper end of the protective roller 3034 is connected with the cover plate 3032. The counterbore 3035 is arranged on the buffer frame 3031. The guide connecting rod 3036 and the limiting block 3037 are fixedly connected, the guide connecting rod 3036 penetrates through the buffer frame 3031, the limiting block 3037 is located in the counterbore 3035, the tail end of the guide connecting rod 3036 is threadedly connected to the mounting back plate 305, and the buffer spring 3038 is sleeved on the guide connecting rod 3036 and located between the buffer frame 3031 and the mounting back plate 305.

[0023] In the opening and closing process of the movable door structure 3, the door body 301 moves on the fixed door 1 with the tempered glass 304 and the rubber strip 302. In the closing process, the rubber strip 302 plays a buffering role. In the opening process, if the passenger's foot collides, the foot first collides with the buffer frame 3031 or the protective roller 3034. After the protective roller 3034 is stressed, it rotates in the square groove 3033, thereby reducing the force caused by the collision. After the buffer frame 3031 is stressed, it moves along the guide connecting rod 3036 towards the mounting back plate 305, thereby compressing the buffer spring 3038 to form a buffering and anti-collision effect. During the entire collision process, the protective roller 3034 and the buffer frame 3031 move in coordination, so that the bottom of the movable door structure 3 has good anti-collision effect. After the foot leaves the buffer assembly 303, under the action of the buffer spring 3038, the buffer frame 3031 moves out with the protective roller 3034 to reset. Due to the action of the limiting block 3037 and the counterbore 3035, the buffer frame 3031 will not fall off the guide connecting rod 3036, thereby ensuring the subsequent buffering effect.

[0024] It should be noted that, through the setting of the movable door structure 3, the buffer assembly 303 is arranged on the mounting back plate 305 at the lower end of the door body 301, when the buffer frame 3031 is impacted, it will move along the guide connecting rod 3036 and compress the buffer spring 3038, thereby forming the effect of buffer anti-collision, avoiding the passengers' feet from being injured by the larger collision with the movable door structure 3, and at the same time, the movable door structure 3 can be protected, the limiting block 3037 at the end of the guide connecting rod 3036 is located in the counterbore 3035, which can limit the buffer frame 3031, preventing the buffer frame 3031 from falling off, the square groove 3033 and the cover plate 3032 are arranged on the buffer frame 3031, the protection roller 3034 is arranged in the square groove 3033, and the cover plate 3032 is limited and connected, when the collision occurs, the protection roller 3034 can roll, further reducing the damage caused by the collision, the anti-collision effect is excellent, and the movable door structure 3 can not only isolate, but also play the role of anti-collision, so that the shielding door function is diversified.

[0025] The above describes the use principle, characteristics and beneficial effects of the present application. Those skilled in the art can understand the above content, and the above content does not limit the present application. The above examples and description of the specification describe the basic principle and characteristics of the present application, and the present application can be variously changed and improved under the premise of meeting the concept of the present application, and these improvements should fall within the scope of the present application.
