[0022] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0023] like Figure 1 , 2 As shown, a liftable isolation fence includes a plurality of lift fence units, and two adjacent lift fence units are fixedly connected by a connecting assembly. Each lift fence unit includes an upper column 8 and a lower column 1 arranged on the left and right and plugged in up and down. The two upper columns 8 and the two lower columns 1 are respectively connected with an upper mesh sheet 11 and a lower mesh sheet 7 arranged in a staggered manner.

[0024] like Figure 3 , 4As shown in Figures 5 and 6, the lower column 1 and the upper column 8 are made of high-strength lightweight materials, and the surface is treated to enhance wear resistance and weather resistance. The column bodies are all rectangular, and a sliding groove is set on the lower column 1. The sliding groove contains the upper column 8 for sliding up and down. The lower column 1 and the upper column 8 are both provided with telescopic fixing holes 5. The side of the upper column 8 is provided with a T-shaped rivet 9 connected to the mesh sheet 11. The T-shaped rivet 9 is provided with a circular hole for fixing the mesh sheet 11 and reinforcing the mesh sheet 11, ensuring that the mesh sheet 11 of the lifting grid unit is lifted and lowered smoothly and accurately positioned, and can also improve the ability of the isolation grid to resist external force deformation.

[0025] The upper mesh sheet 10 is made of a lightweight metal welded standard mesh sheet, and the lower mesh sheet 7 is made of a lightweight metal welded 4 times standard mesh sheet, and the enlarged mesh openings reduce wind resistance and reduce the hidden dangers of preparing snow and sand.

[0026] like Figure 2 , 3 As shown in 4, both ends of the lower mesh 7 are fixedly connected to the fixing nails 6 arranged on the end surface of the lower column 1, and the lower mesh 7 is fixed to the fixing nails 6 on the sides of the two lower columns 1 by welding or binding.

[0027] like Figure 5 As shown, a plurality of T-shaped rivets 9 capable of passing through the through slots 3 provided on the lower column 1 are fixed to the side of the upper column 8 , and both sides of the upper mesh sheet 10 are fixedly connected to the T-shaped rivets 9 fixed to the side of the upper column 8 .

[0028] like Figure 1 As shown, the connection assembly includes a plurality of connection ear plates 4 fixed to the outer side of the lower column 1 and a plurality of connection plates 11 connected between the upper columns 8 .

[0029] like Figure 1 As shown, the connecting ear plates 4 corresponding to two adjacent lower columns 1 are fixed by bolts, and the connecting ear plates 4 of adjacent lower columns 1 are combined and fixed by bolts at the holes, so that multiple units are connected into a whole.

[0030] like Figure 1 As shown, a plurality of connecting plates 11 are located on the upper portion of the lower column 1 , so that the connecting plates 11 will not interfere with the lower column 1 .

[0031] The implementation principle of a liftable isolation fence in the embodiment of the present application is:

[0032] Two lower columns 1, upper columns 8, a lower mesh sheet 7 and an upper mesh sheet 10 form a lifting grid unit. When in use, the lower column 1 of the lifting grid unit can be fixed in the use environment, and the fixing rod 2 is inserted into the ground or concrete block 12 (such as Figure 6 , 7 As shown), the column and the whole of the lifting grid unit are fixed, and the length of the fixing rod 2 of the column can be appropriately adjusted according to different environments;

[0033] With the T-shaped rivets 9 of the lower column 1 facing outward, fix the mesh sheet 10 and the lower mesh sheet 7 on the two upper columns 8 and the lower column 1 by wire or welding, and fix the mesh sheet 10 and the lower mesh sheet. After fixing, adjust the height of the mesh sheet 10 according to the site conditions. When adjusting the height, extend the upper columns 8 connected to both sides of the mesh sheet 10 along the sliding grooves of the lower column 1, adjust the appropriate position of the rise and ensure that the telescopic fixing holes 5 of the upper column and the lower column are aligned, insert the screw from the outside, and fix it with the nut on the inside. Complete the installation of a lifting grid unit;

[0034] After fixation, the adjacent lifting and lowering grille units are fixed by connecting components to form a whole to improve stability. When the connecting components are connected, the upper column 8 that is higher than the upper part of the lower column 1 is connected to the telescopic fixing hole 5 by using a connecting plate 11 and bolts, and the lower columns 1 are fixed with corresponding multiple pairs of connecting ear plates 4 to achieve a stable connection of the lifting and lowering grille units. In this way, the overall resistance to external force deformation of the isolation fence is strong, and it is easy to maintain and repair. At the same time, it can adapt to more scenes and environments, resist damage and isolation of large animals, and it also has the advantages of simple structure, easy installation, beautiful appearance and practicality.
