[0039] How it works

[0040] The park access control device is fixed on the ground through the base on the hollow column 1. When in use, the camera on the hollow column 1 identifies the passing vehicles and feeds back to the controller. When the passage is allowed, the controller starts the servo motor 204 to rotate the output shaft of the servo motor 204, so that the threaded rod 205 rotates, and the threaded rod 205 is threadedly connected with the movable sleeve 202, so that the movable sleeve 202 slides in the fixed sleeve 201, and when the threaded rod 205 rotates, the guide groove 401 squeezes the guide block 402, so that the threaded sleeve 206 rotates, so that the fixed block 207 and the threaded sleeve 206 are connected. The threaded connection allows the extension sleeve 203 to slide in the movable sleeve 202, and the guide block 402 to slide in the guide groove 401. When the threaded sleeve 206 rotates, the rotating block 302 will rotate in the rotating groove 301 until the extension sleeve 203 moves to a suitable position. At this time, the vehicle can pass. After the vehicle passes, the servo motor 204 is controlled to rotate the output shaft of the servo motor 204 in the opposite direction, so that the movable sleeve 202 slides in the opposite direction in the fixed sleeve 201, and the extension sleeve 203 slides in the opposite direction in the movable sleeve 202 until the extension sleeve 203 slides to its original position.
