DETAILED DESCRIPTION

[0023] like Figure 1-Figure 6 As shown, the utility model is described in detail. For the convenience of description, the directions mentioned below are defined as follows: the up, down, left, right, front and back directions mentioned below are Figure 1The up-down, left-right, front-back directions of the projection relationship are consistent. A highway construction fence of the utility model includes a box body 13, a grid 11 is arranged on the top of the box body 13, grooves 14 are arranged on the front and rear sides of the box body 13, a plurality of reflective strips 12 are arranged in the grooves 14, and an inner cavity 16 is arranged in the box body 13.

[0024] Advantageously, a rotating threaded shaft 28 and a sliding rod 15 are disposed in the inner cavity 16 , and the sliding rod 15 and the rotating threaded shaft 28 are respectively located on two sides of the inner cavity 16 .

[0025] Advantageously, a cavity 22 is further provided in the box body 13 , and a turntable 21 is provided on the top of the rotating threaded shaft 28 , and the turntable 21 is located in the cavity 22 .

[0026] Advantageously, a swing plate 26 is hingedly provided at the front and rear sides of the bottom of the inner cavity 16 , and a plurality of counterweight plates 32 are provided inside the swing plate 26 .

[0027] Advantageously, a sliding slot 31 is provided in the swing plate 26, and the counterweight plate 32 is slidably inserted into the sliding slot 31, and bolts are provided in the through holes on the swing plate 26 to be threadedly connected with the counterweight plate 32.

[0028] Advantageously, a lifting plate 24 is slidably disposed on the outer side of the slide rod 15 , and the lifting plate 24 is threadedly connected to the rotating threaded shaft 28 .

[0029] Advantageously, a plurality of rotating seats 23 are provided at the bottom of the lifting plate 24, a swing rod 25 is hingedly provided inside the rotating seat 23, and the swing rod 25 is hingedly provided to one side of the swing plate 26. After the lifting and lowering movement of the lifting plate 24, the swing rod 25 swings, so that the swing plates 26 on both sides swing around the bottom of the inner cavity 16 and simultaneously approach or move away from the inner cavity 16.

[0030] Advantageously, the swing plate 26 is swung upward and hidden in the groove 14 , so that the swing plate 26 abuts against the groove 14 , and the swing rod 25 is folded between the swing plates 26 on both sides, and the swing rod 25 remains in an inclined state.
