[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-6 As shown, a guardrail for highway construction consists of a railing 1, a frame 2, and a vertical plate 3. A first fixing block 8 is fixed to the surface of the vertical plate 3, and a first fixing frame 7 is fixed to the surface of the other side of the first fixing block 8. A second fixing block 11 is slidably connected to the surface of the vertical plate 3, and a second fixing frame 12 is fixedly connected to the surface of the second fixing block 11. A second limiting structure 9 is provided on the surface of the second fixing frame 12. A flap 5 is hinged to the bottom of the vertical plate 3. A connecting plate 14 is fixedly connected to both sides of the bottom of the frame 2. A push rod 15 is slidably connected inside the connecting plate 14. A limiting ring 16 is fixedly connected to one end of the push rod 15. A first limiting structure 6 is provided at the bottom of both the front and rear sides of the frame 2.

[0021] The first limiting structure 6 includes a fixed plate 61, a connecting post 62, and a movable plate 63. The surface of the fixed plate 61 is fixed to the bottom of the surface of the frame 2. One end of the connecting post 62 is fixedly connected to the surface of the other side of the fixed plate 61. The movable plate 63 is rotatably connected to the surface of the connecting post 62. With the setting of the first limiting structure 6, when the flip plate 5 needs to be unfolded, the movable plate 63 can be rotated to cancel the limiting of the flip plate 5. When the flip plate 5 needs to be retracted, the movable plate 63 can be rotated. When the flip plate 5 flips to fit the frame 2, the inertia of the movable plate 63 limits the flip plate 5.

[0022] The second limiting structure 9 includes a connecting rod 91, a locking plate 92, a movable block 93, a moving disk 94, a spring 95, and teeth 96. Both ends of the connecting rod 91 are slidably connected to the interior of the movable block 93, and the interior of the movable block 93 is slidably connected to the moving disk 94. The moving disk 94 is fixed to the surfaces of both ends of the connecting rod 91. One end of the spring 95 is fixedly connected to the moving disk 94, and the other end of the spring 95 is fixedly connected to the inner wall of the movable block 93. One end of the connecting rod 91 is fixedly connected to the locking plate 92. The number of teeth 96 is... Several teeth 96 are fixed to the surface of the vertical plate 3. With the setting of the second limiting structure 9, when the warning sign is placed on the first fixing frame 7, the connecting rod 91 can be pulled to release the limiting of the second fixing frame 12. At the same time, the second fixing frame 12 is moved downward. When the inside of the second fixing frame 12 contacts the surface of the top of the warning sign, the connecting rod 91 is released. At this time, the clamping plate 92 engages with the teeth 96, which can not only limit and fix the warning sign, but also adjust it according to the different sizes of the warning sign.

[0023] The surface of the first fixing frame 7 is threaded with a fixing bolt 13, and the other end of the fixing bolt 13 is in contact with the warning sign. By setting the fixing bolt 13, when the warning sign is fixed between the first fixing frame 7 and the second fixing frame 12, the fixing bolt 13 is rotated. When the surface of the fixing bolt 13 contacts the surface of the warning sign, the rotation of the fixing bolt 13 is stopped, and the warning sign can be fixed.

[0024] The surface of the frame 2 is equipped with reflective markings 4. The reflective markings 4 can attract attention during the day with their bright colors and provide warnings at night with their reflective materials, forming all-weather safety protection.

[0025] The surface of the connecting rod 91 is provided with an anti-slip sleeve 10. With the anti-slip sleeve 10, when the operator pulls the connecting rod 91, the wear on the palm caused by holding the connecting rod 91 can be reduced, and it is not easy to slip out of the hand.

[0026] Working principle: During highway construction, workers need to place guardrails. Depending on the work location, different warning signs are placed on the first fixed frame 7. Then, by pulling the connecting rod 91, the moving plate 94 moves, compressing the spring 95 and simultaneously moving the clamping plate 92. The clamping plate 92 disengages from the teeth 96, releasing the limit on the second fixed frame 12. At this point, the second fixed frame 12 is moved downwards. When the interior of the second fixed frame 12 contacts the top surface of the warning sign, the connecting rod 91 is released, and the elasticity of the spring 95... The force drives the moving plate 94 and the clamping plate 92 back to the starting position. At this time, the clamping plate 92 and the teeth 96 continue to mesh, thereby limiting the warning sign. Then, rotate the fixing bolt 13 until the surface of the other end of the fixing bolt 13 contacts the surface of the warning sign. Stop rotating the fixing bolt 13 to fix the warning sign. After that, rotate the moving plate 63 to remove the limit on the flip plate 5. At this time, one end of the flip plate 5 contacts the ground to support the guardrail and improve the stability of the guardrail. Then, pull the push rod 15 until the other end of the push rod 15 is on the surface of the flip plate 5 to limit the flip plate 5.
