[0032] Please refer to Figure 2In order to improve the protective effect of the enclosure, the warning mechanism 5 in the embodiment includes four warning lights 51, two vertical reflective strips 52, two horizontal reflective strips 53, a mesh plate 54 and a clamping plate 56. The four warning lights 51 are fixed at the four corners of the back of the blue color steel plate 2, and the warning lights 51 at the intersection are connected with the red traffic light signal, so as to remind the walking state of the pedestrians at close range. The two vertical reflective strips 52 are fixed at the left and right ends of the back of the blue color steel plate 2, and the two horizontal reflective strips 53 are fixed at the upper and lower ends of the back of the blue color steel plate 2. The vertical reflective strips 52 and the horizontal reflective strips 53 can reflect the light of the vehicle, thereby improving the recognition of the enclosure. Especially in the night or insufficient light environment, the driver and the pedestrian are reminded to pay attention to the existence of the construction site. The front surface of the blue color steel plate 2 is provided with an assembly hole 55, and the mesh plate 54 is arranged in the inner cavity of the assembly hole 55. The mesh plate 54 can be used to see through the enclosure, so that the pedestrians can check the road conditions on the front side through the mesh plate 54 when passing through the enclosure at the intersection, thereby improving the protective effect of the enclosure. The assembly hole 55 is arranged on the blue color steel plate 2 at the intersection, which facilitates the installation of the mesh plate 54. The clamping plate 56 is fixed to the rear side of the mesh plate 54.

[0034] It should be noted that the mesh plate 54 is extruded through the back of the blue color steel plate 2 to the side close to the column 1, so that the mesh plate 54 completely enters the assembly hole 55, and the clamping plate 56 is attached to the blue color steel plate 2.

[0035] Please refer to Figures 3-4 In order to facilitate the installation of the mesh plate 54, the fixing mechanism 6 in the embodiment includes cavities 61 arranged at the top and bottom of the inner cavity of the column 1. The left and right side walls of the inner cavity of the cavity 61 are rotatably connected by a bearing between the opposite sides, and a double screw 62 extends through one end of the cavity 61 to the right side. The left and right ends of the outer surface of the double screw 62 are threadedly connected with a sleeve 63, and the outer surface of the sleeve 63 is fixed with a movable plate 64. When the double screw 62 rotates, the sleeve 63 threadedly connected with the double screw 62 drives the movable plate 64 to move linearly under the limitation of the movable plate 64. The left and right ends of the movable plate 64 extend to the rear side of the blue color steel plate 2 through the cavity 61, and the top and bottom of the movable plate 64 are fixed with a limiting rod 65. The left and right ends of the upper and lower sides of the clamping plate 56 are fixed with a clamping block 66.

[0036] In the embodiment, the two nuts 63 are symmetrically distributed on the left and right ends of the vertical central axis of the bidirectional screw rod 62, the right side of the bidirectional screw rod 62 is fixed with a handle, the top wall and the bottom wall of the cavity 61 are both provided with a sliding groove, the upper and lower sides of the movable plate 64 are both fixed with a sliding block, the sliding block moves horizontally in the sliding groove, and the sliding groove and the sliding block can limit the movement of the movable plate 64 and the nut 63, so that the movable plate 64 and the nut 63 can only move linearly.

[0037] The front surface of the clamping block 66 is provided with a clamping groove, the top and bottom of the opposite side wall of the inner cavity of the clamping groove are both provided with a limiting groove, and the inner diameter of the limiting groove is matched with the outer diameter of the limiting rod 65.

[0038] It should be noted that the two movable plates 64 move in opposite directions, the movement of the two movable plates 64 makes the limiting rods 65 at the left and right ends move, and then the limiting rods 65 enter the inner cavity of the limiting groove, so that the clamping block 66 can be limited, and the mesh plate 54 can be fixed on the outer surface of the blue color steel plate 2.

[0039] It can be understood that pedestrians can view the road conditions in front of the fence at the intersection, improve the protection, and facilitate the installation of the mesh plate 54 by the staff, and facilitate the disassembly and replacement of the damaged mesh plate 54.

[0040] The working principle of the above embodiment is as follows:

[0041] (1) The warning light 51 at the intersection is connected with the red traffic light signal, so as to remind the walking state of the pedestrian at close range, the vertical and horizontal reflection strips 52 and 53 can reflect the light of the vehicle, so as to improve the recognition of the fence, especially in the night or insufficient light environment, the existence of the construction site is reminded to the driver and the pedestrian, the mesh plate 54 can be used to view the road conditions in front of the fence at the intersection.

[0042] (2) The assembly hole 55 is arranged on the blue color steel plate 2 at the intersection, which is convenient for installing the mesh plate 54. When installing, the mesh plate 54 is extruded through the back of the blue color steel plate 2 to the side close to the column 1, so that the mesh plate 54 is completely in the assembly hole 55, the clamping plate 56 is attached to the blue color steel plate 2, the rear end of the movable plate 64 and the limiting rod 65 enter the clamping groove arranged in the clamping block 66, then the handle on one side of the column 1 is turned, so that the bidirectional screw rod 62 is rotated, the rotation of the bidirectional screw rod 62 drives the movable plate 64 to move linearly under the limitation of the screw sleeve 63, at this time, the two movable plates 64 move in opposite directions, the movement of the two movable plates 64 drives the limiting rods 65 at the left and right ends to move, and then the limiting rods 65 enter the inner cavity of the limiting groove, so that the clamping block 66 is limited, and thus the mesh plate 54 can be fixed on the outer surface of the blue color steel plate 2.
