[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1-4 As shown, a subway platform screen door that can improve sound insulation includes a base 1 and a top connecting frame 2. A fixed door 3 is provided between the base 1 and the top connecting frame 2. A movable door 5 is connected to the fixed door 3, and double-layered tempered glass 6 is fixed on the movable door 5. A groove 8 is provided on the fixed door 3, and a clamping structure 9 is provided in the groove 8. A protective glass 4 is fixedly installed on the fixed door 3, and a sealing strip 7 is installed on one side of the movable door 5. One end of the clamping structure 9 is fixed in the groove 8, and the other end of the clamping structure 9 abuts against the movable door 5.

[0020] When using subway platform screen doors, initially, the movable door 5 is closed, and the clamping structure 9 in the groove 8 abuts against the movable door 5. When the subway enters the platform, the clamping structure 9 provides excellent stability, preventing vibration. Combined with the sealing strip 7 and double-layered tempered glass 6, this enhances the overall sound insulation of the screen doors. Passengers can view the track area through the protective glass 4 and double-layered tempered glass 6. After the subway enters the platform, the clamping structure 9 moves aside, and the drive mechanism at the fixed door 3 moves the movable door 5 between the base 1 and the top connecting frame 2, opening the movable door 5, allowing passengers to board and alight. When the subway doors close, the movable door 5 closes simultaneously, and the clamping structure 9 re-engages against the movable door 5, ensuring its stability and further enhancing sound insulation.

[0021] According to the above implementation scheme, the clamping structure 9 includes a micro motor 901, a mounting base 902, a drive screw 903, and an elastic component 904. The micro motor 901 is mounted on the mounting base 902, and the mounting base 902 is fixedly mounted in the groove 8 on the fixed door 3. The drive screw 903 is connected to the rotating shaft of the micro motor 901. The elastic component 904 is mounted in the groove 8 on the fixed door 3, and the elastic component 904 is connected to the drive screw 903.

[0022] The elastic assembly 904 comprises a movable plate 9041, a follower rod 9042, a threaded hole 9043, a movable rod 9044, a rubber block 9045, a pressing spring 9046 and a through hole 9047. The movable plate 9041 is fixedly connected with the follower rod 9042. The threaded hole 9043 is formed in the movable plate 9041 and the follower rod 9042, and the movable plate 9041 and the follower rod 9042 are connected with the driving screw 903 through the threaded hole 9043. The movable rod 9044 and the rubber block 9045 are fixedly connected, the movable rod 9044 is sleeved on the follower rod 9042, the pressing spring 9046 is sleeved outside the follower rod 9042 and the movable rod 9044, and the ends of the pressing spring 9046 are fixedly connected with the movable plate 9041 and the rubber block 9045 respectively. The through hole 9047 is formed in the rubber block 9045.

[0023] When the movable door 5 needs to be opened, the micro motor 901 on the mounting seat 902 drives the driving screw 903 to rotate. Under the driving of the driving screw 903 and the threaded hole 9043, the movable plate 9041 and the follower rod 9042 move along the groove 8, so that the rubber block 9045 and the movable rod 9044 are moved to make room through the pressing spring 9046, and then the opening work of the movable door 5 is carried out. After the movable door 5 is closed, the micro motor 901 drives the driving screw 903 to rotate reversely, drives the movable plate 9041 and the follower rod 9042 to move reversely through the threaded hole 9043, and the whole elastic assembly 904 moves together. When the rubber block 9045 contacts the movable door 5, the rubber block 9045 first elastically deforms through the through hole 9047 to form a buffer protection. With the continuous rotation of the driving screw 903, the movable plate 9041 continues to move, the follower rod 9042 moves in the movable rod 9044, and the movable plate 9041 compresses the pressing spring 9046. Under the action of the pressing spring 9046, the rubber block 9045 tightly abuts against the movable door 5 to provide a support for the movable door 5. When the subway enters, the vibration will not affect the stability of the movable door 5, and the pressing spring 9046 can also absorb kinetic energy, increasing the sound insulation effect of the whole shielding door.

[0024] It needs to be explained that through the abutting structure 9, when the movable door 5 is closed, the micro motor 901 drives the driving screw 903 to rotate, under the action of the driving screw 903, the elastic assembly 904 moves along the groove 8, and finally the end of the elastic assembly 904 abuts against the movable door 5, so that the movable door 5 is fixed by side abutting, the influence of the vibration when the subway drives into the platform is reduced, the movable door 5 can be prevented from vibrating, and the sound insulation effect of the whole screen door is improved. The movable plate 9041, the follow-up rod 9042, the movable rod 9044, the rubber block 9045 and the abutting spring 9046 are arranged in the elastic assembly 904, and there is a buffering effect when abutting, so that the abutting process is elastic abutting, direct impact is avoided to cause damage of the movable door 5, the integrity of the movable door 5 is ensured, and due to the elastic effect of the abutting spring 9046, the vibration force can also be absorbed, the vibration influence when the subway drives into the platform is further reduced, the stability is improved, and the sound insulation effect is improved.

[0025] The above describes the use principle, characteristics and beneficial effects of the utility model. According to the above, the above does not limit the utility model, and the above embodiment and the description of the specification describe the basic principle and characteristics of the utility model. Under the premise of meeting the concept of the utility model, the utility model can also be variously changed and improved, and these improvements should fall within the scope of the utility model.
