[0016] Second, due to the existence of the support plate and the baffle, the height of the top of the shield door body can be effectively increased. Since the heights of different passengers are different, the user can activate the telescopic cylinder to adjust the height of the support plate. The support plate and the baffle can effectively protect taller people in the train waiting area, thereby improving the overall safety of the shield door body. At the same time, when the shield door is closed, its spring seat will push the sealing plate forward. When the two closed sealing plates are attached to each other, their rubber pads will also be attached to each other, thereby avoiding the situation where a gap is left when the shield door body is closed.

After the control module 21 is adjusted, the user slides the protective shell 23. Using the protective shell 23 to protect the control module 21 can effectively prevent the control module 21 from being hit, thereby increasing the service life of the control module 21. At the same time, the user can also view the movement of the control module 21 through the protective glass 25, so as to be able to make adjustments to the control module 21 in time.
[0026] Principle and advantages of use: When in use, the protective plate 17 can protect the front side of the shielding door body 1, thereby effectively improving the protection of the front side of the shielding door body 1. When the protective plate 17 is hit, the impact force of the protective plate 17 will be transmitted to the anti-collision alarm 15 through the sensor head, so that the anti-collision alarm 15 can be sounded, and the sound will be transmitted through the sound outlet 14, so that the staff can know in time which shielding door body 1 is hit, so as to facilitate the maintenance of the shielding door body 1 with potential safety hazards at the first time. At the same time, because the protective plate 17 is placed in the third limiting groove 16 and then fixed by the limiting plate 18, when it is necessary to remove the protective plate 17 When performing maintenance, the user can screw the bolt 20 out of the screw hole 19, and then remove the limit plate 18. Finally, the protective plate 17 can be directly taken out, thereby achieving the purpose of conveniently removing the protective plate 17. Due to the presence of the spring seat 3, the sealing plate 4 can be pushed forward. When the shielding door body 1 is closed, the two sealing plates 4 pushed forward will stick to each other, and the rubber pads 5 will also stick to each other. The rubber product has good anti-slip, sealing and shock absorption properties, so the space closed by the two shielding doors can be completely sealed, thereby avoiding the occurrence of gaps. The first telescopic rod 7 can effectively limit the position of the sealing plate 4, thereby avoiding the angle deviation of the sealing plate 4 when it is pushed forward, so that The stability of the sealing plate 4 is effectively improved. Due to the existence of the support plate 10 and the baffle plate 11, the height of the top of the shielding door body 1 can be effectively improved. Since the heights of different passengers are different, the user can start the telescopic cylinder 13 to adjust the height of the support plate 10. The support plate 10 and the baffle plate 11 can effectively maintain taller people in the train waiting area, thereby improving the overall safety of the shielding door body 1. The second telescopic rod 9 includes a movable rod and a sleeve rod. The movable plate is sleeved on the inner side of the sleeve rod. The bottom end of the sleeve rod is fixedly connected to the inner bottom end of the first limiting groove 8. The top end of the movable rod is fixedly connected to the bottom end of the support plate 10. The second telescopic rod 9 can effectively adjust the bottom end of the support plate 10 without hindering the adjustment of the height of the support plate 10. The limit can avoid the angle deviation when the support plate 10 is adjusted in height. Due to the existence of the power supply module, the power supply module can uniformly supply power to all electrical equipment on the shielding door body 1, and the control module can uniformly control these electrical equipment. It is more convenient and quick for the user to control the operation of the equipment on the shielding door through the control module 21. When the control module 21 is adjusted, the user slides the protective shell 23. Using the protective shell 23 to protect the control module 21 can effectively prevent the control module 21 from being hit, thereby increasing the service life of the control module 21. At the same time, the user can also view the movement of the control module 21 through the protective glass 25, so as to be able to make timely adjustments to the control module 21.
