The entire installation process of the utility model is fast and convenient, which improves the efficiency of workers in installing the guardrail.

[0019] The positioning component includes a rotating shaft 11 rotatably disposed in the inner groove 10 , an incomplete circular positioning block 12 is mounted on the rotating shaft 11 , and a positioning groove 13 cooperating with the incomplete circular positioning block 12 is formed in the upper limit block 8 .

[0020] The movable part includes a slide groove 14 opened in the upper bracket 3, a sliding rack 16 is slidably arranged in the slide groove 14, a spring 15 connected to the sliding rack 16 is arranged in the slide groove 14, and a gear 22 meshing with the sliding rack 16 is installed on the rotating shaft 11.

[0021] An operating groove 18 is formed on the outer wall of the upper bracket 3 , and a connecting rod 17 is connected to the sliding rack 16 . An operating block 19 located in the operating groove 18 is installed on the connecting rod 17 .

[0022] Specifically, in order to allow the upper limit block 8 and the upper clamping block 9 to be inserted into the limit groove 6 and the clamping groove 5 of the upper bracket 3, the operating block 19 is toggled to move the operating block 19 to the other end of the operating groove 18. During the movement of the operating groove 18, the sliding rack 16 is driven by the connecting rod 17 to slide to one side of the spring 15, thereby squeezing the spring 15, and the gear 22 is driven to rotate by the sliding rack 16, thereby driving the rotating shaft 11 to rotate, so that the incomplete circular positioning block 12 rotates, so that the incomplete circular positioning block 12 originally extending into the limit groove 6 is received in the inner groove 10. When the upper limit block 8 is inserted into the limit groove 6 of the upper bracket 3, the upper limit block 8 is inserted into the limit groove 6 of the upper bracket 3. , the upper clamping block 9 is also inserted into the clamping slot 5 of the upper bracket 3, and the lower limit block 20 is inserted into the limit slot 6 of the lower bracket 4, and the lower clamping block 21 is also inserted into the clamping slot 5 of the lower bracket 4, release the operating block 19, and under the action of the spring 15, the sliding rack 16 will be reset, so that the operating block 19 is reset in the operating slot 18. In this process, the sliding rack 16 will drive the gear 22 to rotate in the opposite direction, and then drive the rotating shaft 11 to rotate in the opposite direction, so that the incomplete circular positioning block 12 is reset, so that the incomplete circular positioning block 12 extends into the positioning slot 13 in the upper limit block 8 that is inserted into the limit slot 6, thereby completing the positioning and locking of the upper limit block 8.

[0023] A base 1 is installed at the bottom of the support column 2, and the base 1 increases the contact area between the utility model and the road surface, thereby improving the stability of the placement of the guardrail.

In order to make the upper limit block 8 and the upper clamping block 9 be inserted into the limit groove 6 and the clamping groove 5 of the upper bracket 3, the operating block 19 is toggled so that the operating block 19 moves to the other end of the operating groove 18. During the movement of the operating groove 18, the sliding rack 16 is driven by the connecting rod 17 to slide to one side of the spring 15, thereby squeezing the spring 15, and the gear 22 is driven to rotate by the sliding rack 16, thereby driving the rotating shaft 11 to rotate, so that the incomplete circular positioning block 12 rotates, so that the incomplete circular positioning block 12 originally extending into the limit groove 6 is received in the inner groove 10, and when the upper limit block 8 is inserted into the limit groove 6 of the upper bracket 3, the upper clamping block 9 is also inserted into the clamping groove 5 of the upper bracket 3, and the lower limit block 20 is inserted into the lower When the lower clamping block 21 is also inserted into the clamping slot 5 of the lower bracket 4 in the limiting slot 6 of the bracket 4, the operating block 19 is released. Under the action of the spring 15, the sliding rack 16 will be reset, so that the operating block 19 is reset in the operating slot 18. In this process, the sliding rack 16 drives the gear 22 to rotate in the opposite direction, and then drives the rotating shaft 11 to rotate in the opposite direction, so that the incomplete circular positioning block 12 is reset, so that the incomplete circular positioning block 12 extends into the positioning slot 13 in the upper limit block 8 that is inserted into the limiting slot 6, thereby completing the positioning and locking of the upper limit block 8, and completing the combined installation of the various components of the guardrail.
