[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4, an adjustable traffic isolation guardrail, comprising a column 1, a docking crossbar 2, an insertion crossbar 3 and an isolation vertical bar 4, a counterweight block is arranged in the base at the bottom of the column 1 to help the column 1 to maintain stability, a docking crossbar 2 and an insertion crossbar 3 spliced ​​together are arranged between the two columns 1, and an isolation vertical bar 4 is arranged between the two docking crossbars 2 and the two insertion crossbars 3, the docking crossbar 2 comprises a docking outer frame 21, a docking groove 22 and a limiting groove 23, a docking groove 22 is provided on the inner side of the docking outer frame 21, and a limiting groove 23 is provided on the inner side of the docking groove 22, the insertion crossbar 3 comprises an insertion outer frame 31 and a built-in plug-in plate 32, the insertion outer frame 3 1 is fixedly connected with a built-in plug-in plate 32 on the inner side, and the built-in plug-in plate 32 is inserted in the limiting groove 23, and the built-in plug-in plate 32 slides in the limiting groove 23, and the built-in plug-in plate 32 is inserted into the limiting groove 23, so that the insertion outer frame 31 and the docking outer frame 21 slide in parallel when the limiting is completed. In the process of the insertion outer frame 31 and the docking outer frame 21 sliding against each other, the columns 1 connected to them respectively move accordingly. The more the overlapping part between the insertion outer frame 31 and the docking outer frame 21 is, the shorter the distance between the two columns 1 is, and vice versa, the distance between the two columns 1 is longer, so as to realize the adjustment of the length of a single isolation guardrail.

[0021] Furthermore, a cavity is provided on one side of the docking outer frame 21 away from the docking groove 22, and a limit screw 24 is provided inside the cavity. The limit screw 24 passes through the docking outer frame 21 and is threadedly connected to the docking outer frame 21. When adjusted to a suitable distance, the two limit screws 24 are respectively rotated upward and downward, so that the limit screws 24 pass through the docking outer frame 21 and are squeezed on the insertion outer frame 31 for limiting.

[0022] Furthermore, a splicing frame 5 is fixedly connected to one side of the column 1 away from the docking cross bar 2 or the insertion cross bar 3. When two groups of isolation guardrails need to be spliced, the splicing frame 5 on the outside of the column 1 is docked with the splicing frame 5 on the outside of another group of columns 1 to connect the two groups of isolation guardrails to each other. A threaded half groove 6 is provided on the top of the splicing frame 5.

[0024] Furthermore, the interior of the isolation vertical fence 4 adopts a hollow structure, which can effectively reduce the weight of the isolation vertical fence 4 and keep the center of the isolation guardrail as a whole on the base of the column 1.

[0025] Working principle: The utility model is an adjustable traffic isolation guardrail. When in use, the built-in plug plate 32 is inserted into the limit groove 23, so that the insertion outer frame 31 and the docking outer frame 21 slide in parallel when the limit is completed. In the process of the insertion outer frame 31 and the docking outer frame 21 sliding against each other, the columns 1 connected to the two respectively move accordingly. The more overlapping parts between the insertion outer frame 31 and the docking outer frame 21, the shorter the distance between the two columns 1, and vice versa. The longer the distance between the two columns 1, when adjusted to a suitable distance, the two limit screws 24 are respectively rotated upward and downward, so that the limit screws 24 penetrate the docking outer frame 21 and squeeze on the insertion outer frame 31 for limit, and the length adjustment of the isolation guardrail is positioned, and the splicing frame 5 outside the column 1 is docked with the splicing frame 5 outside the other group of columns 1, and the screw is installed in a complete thread groove composed of two thread half grooves 6 to realize the splicing of the two groups of isolation guardrails.
