[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Example 1, please refer to Figures 1-4 A protective fence for highway construction includes a first fence panel 1 and a second fence panel 2 located on one side of the first fence panel 1. The first fence panel 1 and the second fence panel 2 are of the same size. A connecting groove 3 is fixedly connected to the middle of one side of the first fence panel 1, and two sets of connecting groove columns 11 are fixedly connected to the other side of the first fence panel 1. A slot 4 is opened through the middle of the connecting groove 3. A rotating handle 5 is provided inside the slot 4. Vertical threaded rods 6 are symmetrically arranged on the rotating handle 5. Lifting connecting columns 7 are sleeved on both sets of vertical threaded rods 6.

[0022] Please see Figure 3 The external threads of the two sets of vertical threaded rods 6 are symmetrically arranged. The two sets of lifting connecting rods 7 are threaded through and threaded holes 8 are opened in each other. The lifting connecting rods 7 are threadedly connected to the vertical threaded rods 6 through the threaded holes 8. At least two horizontally arranged guide grooves 9 are opened on the lifting connecting rods 7. The inner wall of the connecting groove 3 is fixedly connected to the guide rail 10, and the guide rail 10 fits into the guide groove 9.

[0023] In this embodiment, the vertical threaded rod 6 and the lifting connecting column 7 are connected by a threaded connection, which is matched with four sets of guide rails 10 and four sets of guide grooves 9 so that the lifting connecting column 7 can be connected to the connecting groove column 11.

[0024] The two sets of lifting connecting columns 7 can be inserted into the two sets of connecting slot columns 11 in opposite directions under the action of the vertical threaded rod 6, and the lifting connecting columns 7 are located inside the connecting slot 3.

[0025] In this embodiment, the first enclosure plate 1 and the second enclosure plate 2 are connected by the cooperation of two sets of lifting connecting columns 7 and two sets of connecting groove columns 11.

[0026] Before highway construction, workers first remove the fastening bolt 19 from the inside of the first through hole 21, then move the clamping plate 15 downwards along the placement groove 12, and then thread the fastening bolt 19 through the two sets of clamping plates 15 and the second through hole 22 to the nut 20. At this time, the movable base plate 13 is in a horizontal state through the first hinge 16, and the movable support plate 14 is in an inclined state through the cooperation of the second hinge 17 and the third hinge 18. Thus, the triangular structure formed provides auxiliary support for the splicing process of the protective fence. Then, according to the construction situation, several sets of first fence panels 1 and second fence panels 2 are spliced ​​together to form a protective fence. Specifically... During assembly, workers can abut the connecting post 11 on the second enclosure 2 against both sides of the connecting groove 3 of the first enclosure 1, and then rotate the rotating handle 5 inside the groove 4 to drive the two sets of vertical threaded rods 6 to rotate together. This allows the lifting connecting post 7 to move relative to the vertical threaded rod 6 through the symmetrical external thread and threaded hole 8. At the same time, under the limiting action of the guide rail 10 and guide groove 9, the lifting connecting post 7 can rotate out of the connecting groove 3 until it extends into the connecting post 11, realizing the function of rapid assembly of several protective enclosures without the need for bolts and nuts, which significantly improves the assembly efficiency of protective enclosures.

The placement groove 12 has a first through hole 21 and a second through hole 22 vertically connected in sequence. A fastening bolt 19 is provided between the two sets of clamping plates 15. A nut 20 is provided on the fastening bolt 19, and the fastening bolt 19 passes through the first through hole 21 and is threadedly connected to the nut 20.

[0029] In this embodiment, the threaded engagement of the fastening bolt 19 and the nut 20 allows the clamping plate 15 to be secured inside the placement slot 12.

[0030] Specifically, after the protective fence is used, the fastening bolt 19 is first removed from the inside of the second through hole 22. Then, the movable base plate 13 is rotated to a vertical position by the first hinge 16. The movable support plate 14 and the clamping plate 15 are rotated to the inside of the placement slot 12 by the second hinge 17 and the third hinge 18. Then, the clamping plate 15 is fixed to the inner top of the placement slot 12 by the fastening bolt 19 and the nut 20 in conjunction with the first through hole 21.
