[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A subway screen door installation structure comprises a screen door body 1, a mounting frame 2 is mounted on the screen door body 1, and the mounting frame 2 is a U-shaped structure, a sealing strip 3 is arranged on the mounting frame 2, and a slot 4 is opened on the screen door body 1;

[0022] The shielding door body 1 and the mounting frame 2 are jointly provided with a fixing assembly, which includes two clamping blocks 51, two clamping slots 52 and a spring 1 53. The two clamping blocks 51 are slidably arranged in the slot 4, and the side surfaces of the clamping blocks 51 and the slot walls of the slot 4 are mutually fitted. The two clamping slots 52 are both provided on the mounting frame 2, and the side surfaces of the clamping blocks 51 and the slot walls of the clamping slots 52 are mutually fitted. The spring 1 53 is arranged between the two clamping blocks 51, and the spring 1 53 is used for automatic resetting of the two clamping blocks 51.

[0023] A control assembly is provided in the slot 4, and the control assembly includes a control block 61, two limit plates 62, two limit rods 63, a spring 2 64, an electromagnet 65, a magnetic block 66 and two connecting rods 67. The control block 61 is placed between the two clamping blocks 51, and the control block 61 is a truncated cone structure. The two limit plates 62 are fixed on the control block 61, and the two limit rods 63 are fixed in the slot 4. The two limit plates 62 are respectively slidably sleeved on the two limit rods 63, and one end of the spring 2 64 is connected to the slot. 4, and the other end is connected to the control block 61. The electromagnet 65 is installed inside the slot 4, and the magnetic block 66 is fixed on the control block 61, and the electromagnet 65 and the magnetic block 66 are arranged opposite to each other. One end of the two connecting rods 67 is fixedly connected to the two card blocks 51 respectively, and the other ends of the two connecting rods 67 are in contact with the control block 61. The staff can indirectly control the positions of the two card blocks 51 by controlling the on and off of the electromagnet 65, so that the staff can quickly disassemble and assemble the mounting frame 2.

[0024] The specific working principle of the utility model is as follows:

[0025] When replacing the sealing strip 3 of the shielding door body 1 proposed by the present invention, the staff first energizes the electromagnet 65. When the electromagnet 65 is energized, magnetism will be generated and the magnetic block 66 will be attracted to make the magnetic block 66 move upward. When the magnetic block 66 moves upward, it can drive the control block 61 to move upward. Since the control block 61 is a truncated cone structure, when the control block 61 moves upward, its small end will move between the two card blocks 51, and the two card blocks 51 will approach each other under the action of the spring 1 53 until the two card blocks 51 are respectively separated from the two card slots 52. Without the restriction of the two card blocks 51, the mounting frame 2 can be separated from the shielding door body 1. Then, the staff puts the new sealing strip 3 is installed on the shielding door body 1. When the mounting frame 2 is assembled in place on the shielding door body 1, the two card slots 52 are just opposite to the two card blocks 51. Then the staff cuts off the power of the electromagnet 65. When the electromagnet 65 is powered off, it no longer attracts the magnetic block 66. The control block 61 moves downward under the action of the spring 2 64. When the control block 61 moves downward, its outer peripheral surface can squeeze the two connecting rods 67, so that the two connecting rods 67 move away from each other, and the two card blocks 51 also move away from each other until the two card blocks 51 are respectively inserted into the two card slots 52, and the installation of the mounting frame 2 is completed. In summary, the quick disassembly and assembly method of the mounting frame 2 is beneficial to the staff to replace the sealing strip 3.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
