[0002] The screen door is an important equipment on the subway platform. It mainly surrounds the subway platform and the train boarding and alighting space in the form of a glass curtain wall, isolating the platform area from the track area. The main purpose of the screen door is to prevent people from falling onto the track and causing accidents, reduce the operating energy consumption of the station's air conditioning and ventilation system, and reduce the impact of train running noise and piston wind on the station, providing passengers with a safe and comfortable waiting environment. It can also avoid delays in operation due to platform accidents, improve the service level of rail transit, and create necessary conditions for the realization of unmanned driving in the rail transit system.

[0003] When the existing screen doors are in use, the moving mechanism is used to open and close the screen doors. When the screen doors are closed, the two screen doors are in contact with each other. However, in the existing screen doors, there is no smoke-proof structure between the two closed screen doors. When the subway arrives and starts to leave, due to the certain speed, the dust in the tunnel will form dust. The dust will enter the platform through the gap between the screen doors, thereby causing internal pollution of the platform, affecting the environmental cleanliness of the platform, and causing a poor riding experience.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 4 As shown, a smoke-proof shielding door body structure comprises a shielding door body 1, a tempered glass 2 is arranged on the shielding door body 1, a smoke-proof frame 5 is arranged on the side of the shielding door body 1, and a rubber sleeve 6 is connected to the smoke-proof frame 5, a buffer plate 7 is arranged on the rubber sleeve 6, and a buffer spring 11 is arranged between the buffer plate 7 and the smoke-proof frame 5, an end deformation structure 8 is installed at the end of the smoke-proof frame 5, a top pulley 3 is installed at the upper end of the shielding door body 1, and a bottom pulley 4 is installed at the lower end of the shielding door body 1, a connecting column 9 is fixed on the smoke-proof frame 5, and the buffer plate 7 is provided on the side of the shielding door body 1. A movable column 10 is fixed on it, and the end of the movable column 10 is inserted into the connecting column 9. The buffer spring 11 is sleeved on the connecting column 9 and the movable column 10. A smoke-proof frame 5, a rubber sleeve 6, a buffer plate 7, a buffer spring 11 and other structures are arranged on the side of the shielding door body 1. When the two shielding door bodies 1 are closed, the rubber sleeve 6 is deformed and tightly abutted together. In this process, the buffer plate 7 is forced to compress the buffer spring 11, which can play a buffering role, and the buffer spring 11 will also play a supporting role to ensure the sealing effect of the rubber sleeve 6.

[0019] When the shielding door is used, after the moving mechanism in the shielding door system is started, the shielding door body 1 is forced to move through the top pulley 3 and the bottom pulley 4, and a part of the upper and lower ends of the shielding door body 1 are both located in the door frame. With the movement of the two shielding door bodies 1, when the two buffer plates 7 come into contact, the shielding door body 1 continues to move, and the buffer plate 7 moves toward the direction of the smokeproof frame 5 through the moving column 10 and the connecting column 9, thereby compressing the buffer spring 11 and causing the rubber sleeve 6 to deform and contact together. At this time, the buffer spring 11 plays a buffering role while playing a supporting role, ensuring that the rubber sleeves 6 on the two shielding door bodies 1 are in close contact, thereby achieving a sealing and smoke-proof effect. In the process of the movement of the buffer plate 7, the end deformation structure 8 can be driven to deform, thereby fitting on the inner wall of the door frame, so that the part of the shielding door body 1 inserted into the door frame also has a good sealing line, thereby ensuring the sealing and smoke-proof effect of the entire shielding door. When the shielding door is opened, the buffer spring 11 resets the buffer plate 7, and the end deformation structure 8 is restored to its initial state.

[0020] According to the above implementation scheme, the end deformation structure 8 includes a fixed plate 801, a driving block 802, a movable rod 803, an inclined block 804, a bottom plate 806, an extension sleeve 807 and an extension component 808. The fixed plate 801 and the driving block 802 are respectively fixed on the smoke-proof frame 5 and the buffer plate 7, the movable rod 803 is connected to the inclined block 804, the bottom plate 806 is connected to the extension sleeve 807, and the bottom plate 806 is fixed on the smoke-proof frame 5. The extension component 808 is arranged The end deformation structure 8 further includes a reset spring 805 inside the bottom plate 806 and the extension sleeve 807. The driving block 802 is provided with a slope surface. The inclined block 804 is placed on the fixed plate 801, and the inclined surface of the inclined block 804 contacts the slope surface on the driving block 802. The movable rod 803 passes through the smoke-proof frame 5 and the extension sleeve 807, and the upper end of the movable rod 803 contacts the extension component 808. The reset spring 805 is sleeved on the movable rod 803, and the reset spring 805 The ends of the expansion assembly 808 are respectively in contact with the smoke-proof frame 5 and the inclined block 804, the expansion assembly 808 includes an elastic sheet 8081, an end plate 8082, a lifting plate 8083 and a limiting frame 8084, the elastic sheet 8081 is fixedly connected to the end plate 8082, and the end plate 8082 contacts the inner wall of the expansion sleeve 807, the lifting plate 8083 is fixed to the bottom end of the elastic sheet 8081, and the lifting plate 8083 contacts the upper end of the movable rod 803, and the limiting frame 8084 is fixed to the bottom plate 80 6, an end deformation structure 8 is installed at the end of the smoke-proof frame 5. When the buffer plate 7 moves, the driving block 802 will move up with the inclined block 804 and the movable rod 803, so that the elastic sheet 8081 in the extension component 808 is deformed and extended, and the end plate 8082 is used to expand outward with the extension sleeve 807, so that after the shielding door body 1 is closed, a seal can also be formed at the position where the shielding door body 1 is inserted into the door frame, thereby ensuring the smoke-proof effect after the entire shielding door is closed.

[0021] When the buffer plate 7 moves, the driving block 802 moves together and applies an upward force to the inclined block 804. The inclined block 804 is subjected to the force to lift the movable rod 803 and compress the reset spring 805. Under the lifting of the movable rod 803, the lifting plate 8083 moves upward and causes the elastic sheet 8081 to deform and expand, thereby using the end plate 8082 to carry the expansion sleeve 807 to expand outward until the expansion sleeve 807 contacts the inner wall of the door frame, so that a sealing effect can be achieved. During the expansion process, the limit frame 8084 limits the elastic sheet 8081 to ensure that the expansion is carried out in the horizontal direction, thereby ensuring the expansion effect. When the buffer plate 7 is reset, under the action of the reset spring 805, the inclined block 804 descends and is placed on the fixed plate 801, and the elastic sheet 8081 and other structures are reset accordingly, so that the end deformation structure 8 is restored to its initial state. The structure is simple and the use effect is good.
