The guide sleeves 62 and the electric push rods 61 are arranged at intervals. Sliding rods 63 are slidably arranged inside the guide sleeves 62. The sliding rods 63 are slidably connected to the fixed plate 1 and the outer cover 2. A connecting frame 64 is provided between two adjacent sliding rods 63, and the top of the telescopic rod of the electric push rod 61 is connected to the bottom of the connecting frame 64 on the same side.

[0076] When people need to use the pedestrian crossing, first install the pedestrian crossing on one side of the zebra crossing so that the fixing plate 1 is close to the ground, and then press the main power switch to power on the pedestrian crossing, and the infrared sensor 56 and the LCD display screen 59 start to work, and the countdown time of the traffic light next to the zebra crossing will be displayed on the LCD display screen 59, so that some short-sighted pedestrians can know the countdown time. When the traffic light next to the zebra crossing turns red, the infrared sensor 56 senses that the red light is on, and the infrared sensor 56 sends a signal, and the control module controls the first warning light 57 to light up, and at the same time, the control module controls the buzzer 54 to sound, thereby reminding pedestrians not to run a red light. At the same time, the control module controls the electric push rod 61 to work for 3 seconds, and the telescopic rod of the electric push rod 61 extends, driving the connecting frame 64 and the sliding rod 63 to move upward, so that the sliding rod 63 extends out of the ground.

[0084] When the sliding rod 63 moves upward, it drives the first sliding frame 1001, the blocking rod 1002, the slider 1003, the connecting rod 1004 and the limiting rod 1006 to move upward. When the limiting rod 1006 contacts the guide sleeve 62, the limiting rod 1006, the first sliding frame 1001 and the slider 1003 stop moving, and the sliding rod 63 drives the blocking rod 1002 and the connecting rod 1004 to continue to move upward. The spring 1005 is compressed, and under the action of the connecting rod 1004, the blocking rod 1002 and the connecting rod 1004 are compressed. Rod 1002 rotates outward to open to prevent pedestrians from passing between the sliding rods 63. When the sliding rod 63 moves downward to reset, it first drives the blocking rod 1002 and the connecting rod 1004 to move downward to reset, and the spring 1005 returns to its original state. Under the action of the connecting rod 1004, the blocking rod 1002 rotates inward to reset. When the spring 1005 is completely reset, the sliding rod 63 drives the limit rod 1006, the first sliding frame 1001 and the slider 1003 to move downward to reset.
