[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-3 The utility model provides a technical solution: an adjustable telescopic construction site guardrail for construction engineering, comprising a hollow body 1, a rectangular tube 2 and a top tube 5.

The adjustment rod 6 is inserted into the top tube 5 for horizontal sliding. The insertion end of the adjustment rod 6 is provided with a threaded groove 16. The screw rod 15 is internally threaded in the threaded groove 16. The end of the screw rod 15 rotates through the top tube 5 and the rotating handle 7 is installed.

[0028] Specifically, when adjusting the distance between the two rectangular tubes 2, the screw rod 15 is driven to rotate by rotating the handle 7, and the rotating screw rod 15 cooperates with the threaded groove 16 provided on the adjusting rod 6, so that the position of the adjusting rod 6 inserted into the top tube 5 can be adjusted. By adjusting the position of the adjusting rod 6, the distance between the two rectangular tubes 2 can be adjusted, thereby realizing the protection of foundation pits of different widths.

[0029] Furthermore, the height adjustment assembly includes a lifting rod 4 and a fixing bolt 3. The lifting rod 4 is slidably inserted into the top of the rectangular tube 2, and the fixing bolt 3 is threaded through the outer side of the rectangular tube 2. The through end of the fixing bolt 3 is used to fix the lifting rod 4. The top of the two lifting rods 4 is sequentially installed to the bottom of the top tube 5 and the adjustment rod 6.

[0030] Specifically, when the height of the top tube 5 needs to be adjusted, the position is adjusted by pulling the lifting rod 4 inserted into the rectangular tube 2, and then the fixing bolt 3 threaded through the rectangular tube 2 is rotated so that the through end of the fixing bolt 3 contacts the lifting rod 4, thereby fixing the lifting rod 4 and adjusting the height of the top tube 5 at the same time.

[0031] Furthermore, a hollow body 1 is installed at the bottom of each of the two rectangular tubes 2, a water inlet 17 is installed at the top of each of the hollow bodies 1, and a drain outlet 12 is opened on the outside of each of the hollow bodies 1;

[0032] Specifically, after the hollow body 1 is placed, water is added into the hollow body 1 through the water inlet 17, thereby increasing the weight of the hollow body 1 and ensuring the stability of the hollow body 1 during use. When the hollow body 1 is not in use, the water can be discharged through the drain outlet 12, thereby reducing the weight of the guardrail and facilitating its movement.

[0033] Furthermore, a guide tube 14 is installed on the outside of the rectangular tube 2, and a guide body 13 is slidably inserted into the end of the guide tube 14, and the end of the guide body 13 is connected to the outer wall of the rectangular tube 2;

[0034] Specifically, when the distance between the two rectangular tubes 2 is adjusted, the stability between the rectangular tubes 2 can be increased through the cooperation between the guide tube 14 and the guide body 13 .

[0035] Furthermore, the reminder assembly includes a bearing 8, a mounting post 9 and a flag 11. The bearing 8 is mounted on the top of the top tube 5, and the mounting post 9 is mounted on the bearing 8, and the flag 11 is mounted on the mounting post 9;

[0036] Specifically, in order to improve the eye-catching effect of the guardrail, the coordination of the installation posts 9 and the flags 11 can further increase the attractiveness of the guardrail, so that pedestrians can discover the foundation pit immediately.

[0037] Furthermore, a plurality of fan blades 10 are installed on the outside of the mounting column 9;

[0038] Specifically, the fan blades 10 installed on the mounting column 9 rotate under the action of wind, and the fan blades 10 drive the mounting column 9 to rotate, and the mounting column 9 can drive the flag 11 to rotate, which can further increase the attention of pedestrians.

[0039] Working principle: When using the adjustable telescopic construction site guardrail for construction projects, when adjusting the distance between the two rectangular tubes 2, the screw rod 15 is driven to rotate by rotating the handle 7, and the rotating screw rod 15 cooperates with the threaded groove 16 provided on the adjusting rod 6, so that the position of the adjusting rod 6 inserted into the top tube 5 can be adjusted. By adjusting the position of the adjusting rod 6, the distance between the two rectangular tubes 2 can be adjusted, so that foundation pits of different widths can be protected. In order to improve the eye-catching effect of the guardrail, the coordination of the installation column 9 and the flag 11 can further increase the attractiveness of the guardrail, so that pedestrians can discover the foundation pit at the first time.
