The utility model has a simple structure, an ingenious design, saves human resources, can meet market demand, and is suitable for promotion.When the utility model is used, the base 5 is fixedly installed at two diagonal corners of the intersection, and the first protective plate 1, the second protective plate 2 and the third protective plate 3 are rotated along the axis of the corresponding column 4 by the second driving device or manually. The moving direction of the guide wheel 8 is always perpendicular to the line between the axis of the guide wheel 8 and the axis of the column 4. When the guide wheel 8 drives several universal wheels 6 to rotate along the axis of the column 4, the moving direction of the universal wheel 6 is also perpendicular to the line between the axis of the universal wheel 6 and the axis of the corresponding column 4, so that the first protective plate 1, the second protective plate 2 and the third protective plate 3 are rotated along the axis of the column 4. It is more labor-saving when the plate 3 rotates along the axis of the column 4 until the two first protective plates 1, the second protective plate 2 and the third protective plate 3 are respectively horizontal, thereby blocking the flow of people on the longitudinal road and allowing the flow of people on the transverse road to pass; similarly, the first protective plate 1, the second protective plate 2 and the third protective plate 3 are driven by the second driving device or manually to rotate along the axis of the corresponding column 4, and the moving direction of the guide wheel 8 is always perpendicular to the line between the axis of the guide wheel 8 and the axis of the column 4. The guide wheel 8 rotates along the axis of the column 4, driving several universal wheels 6 to rotate along the axis of the column 4. The moving direction of the wheel 6 is also perpendicular to the line connecting the universal wheel 6 and the axis of the corresponding column 4, so that the first guard plate 1, the second guard plate 2 and the third guard plate 3 can be rotated along the axis of the column 4 more labor-saving, until the two first guard plates 1, the second guard plates 2 and the third guard plates 3 are respectively vertical, thereby blocking the flow of people on the horizontal road and allowing the flow of people on the longitudinal road to pass; when the device is not needed, the first guard plate 1, the second guard plate 2 and the third guard plate 3 are rotated along the axis of the corresponding column 4, so that the first guard plate 1, the second guard plate 2 and the third guard plate 3 are aligned with the road The edges are fitted together and put away so as not to hinder traffic. When the road surface is wide, the movable end of the electric push rod 7 is controlled to shorten and drive the guide wheel 8 to move upward, thereby separating the guide wheel 8 from the ground. Then the first driving device drives the first guard plate 1 and the second guard plate 2 to move away from the column 4. At this time, the moving direction of the universal wheel 6 is parallel to the moving direction of the first guard plate 1 and the second guard plate 2, which facilitates the movement of the first guard plate 1 and the second guard plate 2, thereby increasing the sum of the lengths of the first guard plate 1, the second guard plate 2 and the third guard plate 3 to adapt to intersections with wider widths.

[0017] Specifically, as shown in the figure, the first driving device of this embodiment includes a first motor 20, and the first motor 20 is fixedly installed on the first protective plate 1. A dark groove 21 is provided on the first protective plate 1. Two screw rods 22 are rotatably installed in the dark groove 21 through bearings. The two screw rods 22 are distributed front and back, and one end of one screw rod 22 is fixedly connected to the output shaft of the first motor 20, and one end of the corresponding screw rod 22 passes through a reserved hole on the inner wall of the dark groove 21, and is fixedly connected to the output shaft of the first motor 20 located in the reserved hole and is coaxially arranged. The output shaft of the first motor 20 and one end of the corresponding screw rod 22 are rotatably installed in the reserved hole through bearings. Inside, the outer periphery of the screw rod 22 is fixedly installed with a gear ring 23, and the two gear rings 23 are meshed together. The outer periphery of the screw rod 22 is threadedly installed with a nut 24, the front nut 24 is located at the left end of the corresponding screw rod 22, and the rear nut 24 is located at the right end of the corresponding screw rod 22. The screw rod 22 is coaxially arranged with the corresponding gear ring 23 and nut 24, and a slide groove 25 is respectively provided on the front and rear sides of the inner wall of the concealed groove 21. A slider 26 is respectively slidably installed in the slide groove 25, and one side of the slider 26 is fixedly connected to the outer periphery of the corresponding nut 24, and the other side of the slider 26 is respectively fixedly connected to one side of the corresponding second protective plate 2 and the third protective plate 3. Start the first motor 20 to make the output shaft of the first motor 20 rotate in the forward direction. The rotation of the output shaft of the first motor 20 drives the screw rod 22 and the gear ring 23 on the rear side to rotate. Since the two gear rings 23 are meshed, the rotation of the gear ring 23 on the rear side drives the screw rod 22 on the front side to rotate through the gear ring 23 on the front side. Since the rotation directions of the two gear rings 23 are opposite, the rotation directions of the two screw rods 22 are also opposite. The two screw rods 22 rotate in opposite directions and drive the corresponding nut 24 to move in opposite directions relative to the screw rod 22. That is, when the nut 24 on the front side drives the second guard plate 2 and the corresponding slider 26 to move to the right relative to the first guard plate 1, the nut 24 on the rear side gives The third protective plate 3 and the corresponding slider 26 have a leftward force. Since the third protective plate 3 is fixed, the third protective plate 3 gives the first protective plate 1 a rightward reaction force, so that the first protective plate 1 moves to the right relative to the third protective plate 3, thereby stretching the first protective plate 1, the second protective plate 2 and the third protective plate 3, so that the length of the first protective plate 1, the second protective plate 2 and the third protective plate 3 is maximized, which is convenient for intercepting the flow of people; similarly, the output shaft of the first motor 20 is rotated in the opposite direction, and the first protective plate 1, the second protective plate 2 and the third protective plate 3 are stored, and the length of the first protective plate 1, the second protective plate 2 and the third protective plate 3 is minimized, which is convenient for storage.

[0018] Specifically, as shown in the figure, the second driving device of this embodiment includes a second motor 30, the second motor 30 is fixedly mounted on the second protective plate 2, the output shaft of the second motor 30 is fixedly connected to the fixed end of the telescopic shaft 31, the movable end of the telescopic shaft 31 is fixedly connected to one side of the first bevel gear 32, the outer periphery of the movable end of the telescopic shaft 31 is rotatably mounted on a shaft seat, the shaft seat is fixedly mounted on the movable end of the electric push rod 7, the output shaft of the second motor 30, the telescopic shaft 31, the shaft seat and the first bevel gear 32 are coaxially arranged, one side of the first bevel gear 32 is meshingly matched with a second bevel gear 33, the second bevel gear 33 is fixedly mounted on the guide wheel 8, and the second bevel gear 33 is coaxially arranged with the guide wheel 8. Start the second motor 30 to make the output shaft of the second motor 30 rotate in the forward direction. The forward rotation of the output shaft of the second motor 30 drives the telescopic shaft 31, the first bevel gear 32, the second bevel gear 33 and the guide wheel 8 to rotate in the forward direction around the axis of the column 4. Similarly, the output shaft of the second motor 30 is rotated in the reverse direction to make the guide wheel 8 rotate in the reverse direction along the axis of the column 4. When the second protective plate 2 is manually pushed to rotate along the axis of the column 4, the guide wheel 8 rotates under the friction with the ground, and the rotation of the guide wheel 8 drives the second bevel gear 33, the first bevel gear 32, the telescopic shaft 31 and the output shaft of the second motor 30 to rotate.

[0019] Further, as shown in the figure, in this embodiment, a plurality of through slots 40 are respectively provided on the first protective plate 1, the second protective plate 2 and the third protective plate 3. The through slots 40 can reduce the windward area of ​​the first protective plate 1, the second protective plate 2 and the third protective plate 3, thereby reducing the force of the wind on the first protective plate 1, the second protective plate 2 and the third protective plate 3, and reducing the possibility of the first protective plate 1, the second protective plate 2 and the third protective plate 3 being blown down by the wind; at the same time, the through slots 40 can reduce the weight of the first protective plate 1, the second protective plate 2 and the third protective plate 3, and reduce the material consumption of the first protective plate 1, the second protective plate 2 and the third protective plate 3.
