[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

The right part of the surface is meshed with gear 45, and the middle part of the bottom end of gear 2 43, gear 3 44 and gear 4 45 are all rotatably connected to a fixed barrel 46, and the bottom wall of the fixed barrel 46 is fixedly connected to the bottom wall of the shell 1. The middle part of the inner cavity of gear 2 43, gear 3 44 and gear 4 45 is provided with an internal thread, and the middle part of the inner cavity of gear 2 43, gear 3 44 and gear 4 45 is threadedly connected with a threaded rod 47. The three threaded rods 47 are meshed with the corresponding gear 2 43, gear 3 44 and gear 4 45, and the threads of the threaded rod 47 located in the middle are set in opposite directions;

[0026] The limiting assembly 2 includes a shell 21, the bottom wall of the shell 21 is fixedly connected to the upper end of the outer shell 1, and four limiting assemblies 22 are fixedly connected to the inner cavity of the shell 21, and the four limiting assemblies 22 are evenly distributed vertically. A plurality of matching holes 23 are provided on the outer surface of the limiting assembly 22. The limiting assembly 22 includes a fixing ring 221, and a plurality of sliding grooves are provided on the inner surface of the fixing ring 221. A plurality of limiting blocks 223 are slidably connected in the plurality of sliding grooves. A rubber ring 222 is fixedly connected to the middle of the inner cavity of the fixing ring 221, and the bottoms of the ends of the plurality of limiting blocks 223 that are close to each other are all inclined, and the ends of the plurality of limiting blocks 223 that are away from each other are all inclined, and the ends of the plurality of limiting blocks 223 that are close to each other are all provided with connecting holes that match the rubber ring 222.

[0027] In order to achieve the purpose of restricting pedestrians during the specific implementation of this solution, it is first necessary to install the device housing 1 at the traffic light, further make the upper end of the device housing 1 be horizontally set with the roadbed, and further set the device motor 41 to rotate by driving the device gear 1 42 during the rotation process, so that the gear 1 42 can drive the device gear 2 43 to engage during the rotation process, and then the device gear 2 43 rotates, and further when the device gear 2 43 rotates, it can drive the meshing device gear 3 44 to engage, and further drive the device gear 4 45 meshing on the right part of the outer surface of the gear 3 44 to rotate, so that when the device gear 2 43, gear 3 44 and gear 4 45 rotate, the corresponding threaded rod 47 can be driven to rotate, so that the threaded rod 47 rises, and when the device threaded rod 47 rises, the bottom ends of the several limiting blocks 223 are inclined, and the device limiting blocks 223 can be pushed out to the outer surface of the matching hole 23, thereby achieving the purpose of restricting pedestrians.

[0028] When the light turns green, the device will use the controller to cause the device motor 41 to flip, thereby driving the corresponding device threaded rod 47 to descend through gear 1 42, gear 2 43 and gear 3 44. When the device threaded rod 47 descends to the appropriate position, the plurality of device limiting blocks 223 will contract due to the elasticity of the device rubber ring 222, thereby releasing the limit of the device, so that pedestrians can pass smoothly.

[0029] In addition, in this solution, a receiver is installed inside the device indicator 3 and needs to be used in conjunction with a controller, wherein the device receiver and the controller are both existing technologies. The working principle of the device controller is: receiving data sent by the controller in the form of Bluetooth, thereby changing the time of forward and reverse rotation of the motor 41;

[0030] The working principle of the device controller is as follows: by sending data in the form of Bluetooth, the parameters of the forward and reverse rotation time of the motor 41 can be adjusted through manual operation, thereby facilitating the control of pedestrian movement and thus avoiding accidents;

[0031] It should be further explained that indicator lights are provided at the front and rear ends of the outer surface of the device indicator sign 3, so that when pedestrians are waiting, the color of the indicator lights at the front and rear ends of the device indicator sign 3 will remind pedestrians, thereby warning pedestrians whether they can pass through during this time period. Further, by setting the bottom ends of the device gear 2 43, gear 3 44 and gear 4 45 to be rotatably connected to the fixed barrel 46, the device fixed barrel 46 can support the gear 4 45, thereby preventing the device from falling. Further, by setting the device gear 3 44 located in the middle to be set in the opposite direction, the device gear 2 43, gear 3 44 and gear 4 45 can rotate in the same direction.

[0032] It should be further explained that the circuit connections in this solution are all existing technologies and will not be elaborated in detail in this solution.

[0033] The working principle of the present invention is as follows: first, when the operator uses the device, he first installs the device at the traffic light, further buries the device housing 1 underground and makes the upper end of the housing 1 level with the roadbed, and then adjusts the internal parameters of the device indicator 3 through the controller equipped with the device, so that the second count of the device is consistent with the traffic light. Further, when the light is red, the device motor 41 rotates under the control of the device indicator 3, thereby driving the device gear 1 42 fixed to the output end to rotate, and further the device gear 1 42 rotates. At the same time, it will drive the device gear 2 43 engaged on the right side of the outer surface to rotate. Further, when the device gear 2 43 rotates, it will drive the device gear 3 44 engaged on the right side to rotate. Further, when the device gear 3 44 rotates, it will drive the gear 4 45 on the right side of the outer surface to rotate, thereby driving the corresponding device threaded rod 47 to rise. When the device threaded rod 47 rises, several device limiting blocks 223 can be extended through the matching holes 23 to block pedestrians, thereby preventing pedestrians from running red lights and causing accidents.
