[0020] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 4 As shown, a light warning device for road and bridge construction provided by an embodiment of the utility model comprises a warning light 1 and a bracket 2, the bottom of the warning light 1 is fixedly connected to the top of the bracket 2, the bottom of the bracket 2 is fixedly connected to a mounting shell 3, the surface of the mounting shell 3 is movably connected to a fixed shell 4, the bottom of the fixed shell 4 is fixed to the surface of the road and bridge, the top of the fixed shell 4 is provided with a protective cover 5, the bottom of the inner cavity of the mounting shell 3 is movably connected to a control rotating block 6 through a rotating shaft, the top of the control rotating block 6 passes through the mounting shell 3 and extends to the outside of the inner cavity of the mounting shell 3, and a limiting device 7 is provided inside the mounting shell 3.

[0022] refer to Figure 4 The limiting device 7 includes two limiting blocks 701, and the opposite sides of the two limiting blocks 701 penetrate the mounting shell 3 and extend to the outside of the inner cavity of the mounting shell 3. The front and rear sides of the limiting blocks 701 are fixedly connected with a slider 702. The inner cavity of the mounting shell 3 is provided with two springs 703, and the surface of the spring 703 is fixedly connected with the surface of the slider 702.

[0023] With the above solution, by providing the limiting device 7 , when the warning light 1 is moved to a suitable position, the limiting device 7 has a limiting effect on the position of the warning light 1 .

[0024] refer to Figure 4 The inner cavity of the mounting shell 3 is fixedly connected with two slide frames 8 used in conjunction with the slider 702 , and the surface of the slider 702 is movably connected with the inner cavity of the slide frame 8 .

[0025] By adopting the above solution, by setting the slide frame 8, when the limit block 701 moves, it will drive the slider 702 to move along the inner cavity of the slide frame 8. The cooperation between the slider 702 and the slide frame 8 has a limiting effect on the moving position of the limit block 701.

[0026] refer to Figure 4 The inner cavity of the mounting shell 3 is provided with an extrusion shell 9 used in conjunction with the control rotating block 6, and the surface of the control rotating block 6 contacts the inner cavity of the extrusion shell 9. The top of the limit block 701 is fixedly connected with an extrusion column 10 used in conjunction with the extrusion shell 9, and the surface of the extrusion column 10 contacts the inner cavity of the extrusion shell 9.

[0027] The above scheme is adopted: by setting the extrusion shell 9 and the extrusion column 10, when the extrusion shell 9 moves, it can drive the extrusion shell 9 to move along the surface of the extrusion column 10, the extrusion shell 9 can generate an extrusion force on the extrusion column 10, and the extrusion column 10 subjected to the extrusion force can drive the limit block 701 to move.

[0028] refer to Figure 4 The front side of the extrusion shell 9 is fixedly connected to the outer shell 11 , the inner cavity of the outer shell 11 is movably connected to the inner shell 12 , and the front side of the inner shell 12 is fixedly connected to the inner cavity of the mounting shell 3 .

[0029] The above solution is adopted: by setting the outer shell 11 and the inner shell 12, when the extruded shell 9 moves, the outer shell 11 will be driven to move along the surface of the inner shell 12. The coordinated use of the inner shell 12 and the outer shell 11 has a limiting effect on the moving position of the extruded shell 9.

[0030] refer to Figure 3 The left and right sides of the inner cavity of the fixed shell 4 are both provided with limiting grooves 13 used in conjunction with the limiting block 701 , and the surface of the limiting block 701 contacts the inner cavity of the limiting groove 13 .

[0031] The above scheme is adopted: by setting the limit groove 13, when the mounting shell 3 moves into the inner cavity of the fixed shell 4, the control turn block 6 is released, and the restoring force generated by the spring 703 restoring its shape will drive the limit block 701 to be stuck into the inner cavity of the limit groove 13. The coordinated use of the limit block 701 and the limit groove 13 has a limiting effect on the position of the mounting shell 3.

[0032] refer to Figure 3 The left and right sides of the bottom of the protective cover 5 are fixedly connected with moving blocks 14, and the left and right sides of the top of the fixed shell 4 are provided with moving grooves 15 used in conjunction with the moving blocks 14, and the surface of the moving block 14 is movably connected with the inner cavity of the moving groove 15.

[0033] The above solution is adopted: by setting the moving block 14 and the moving groove 15, when the protective cover 5 moves, the moving block 14 will be driven to move along the inner cavity of the moving groove 15. The coordinated use of the moving block 14 and the moving groove 15 has a limiting effect on the moving position of the protective cover 5.

[0034] The working principle of this utility model:

[0035] During use, when it is necessary to conveniently replace the warning light 1 used in road and bridge construction, the operator first removes the warning light 1 that needs to be replaced, and then pulls the protective cover 5 to the rear side. When the protective cover 5 moves, it will drive the moving block 14 to move along the inner cavity of the moving groove 15. When the protective cover 5 moves to the rear side, the control rotating block 6 is rotated to drive the control rotating block 6 to rotate along the inner cavity of the extrusion shell 9. The extrusion force of the control rotating block 6 on the extrusion shell 9 can drive the extrusion shell 9 to move to the front side. When the extrusion shell 9 moves, it will generate an extrusion force on the two extrusion columns 10. The two extrusion columns 10 subjected to the extrusion force will move toward each other. When the extrusion column 10 moves, it will drive the two limit blocks 701 to move toward each other. When the limit block 701 moves to the inner cavity of the sliding frame 8, the force generated by the movement of the sliding frame 8 causes the spring 703 to undergo elastic deformation. When the limit block 701 is completely moved to the inner cavity of the mounting shell 3, the mounting shell 3 is moved into the inner cavity of the fixed shell 4, and then the control turn block 6 is released. The restoring force generated by the spring 703 restoring its shape will drive the limit block 701 to be stuck into the inner cavity of the limit groove 13. The coordinated use of the limit block 701 and the limit groove 13 has a limiting effect on the position of the mounting shell 3, and the coordinated use of the mounting shell 3 and the fixed shell 4 has a limiting effect on the position of the warning light 1. At this time, the warning light 1 used in road and bridge construction is easily replaced.

[0036] In summary: the light warning device for road and bridge construction solves the problem that existing warning lights can be installed around the construction site to ensure visibility of the construction area by setting a limit device 7, a limit block 701, a slider 702, a spring 703, and a limit groove 13. Bolt installation is usually adopted during installation. The construction site is located outdoors and the environment is relatively complex. The warning lights are prone to damage and need to be replaced. However, the bolts are prone to rust and aging due to excessive moisture. The aging of the bolts increases the difficulty of replacing the warning lights. The torque of the bolts needs to be continuously adjusted during installation. Over-tightening or over-loosening can easily lead to poor installation quality. However, the warning lights used in road and bridge construction do not have components that can be easily replaced.
