[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0020] Reference Figure 1-3 A U-shaped guardrail that is easy to assemble and disassemble includes a guardrail 1. The outer walls of both ends of the guardrail 1 are respectively provided with an adjustment groove 2 and an adjustment groove 3. The guardrail 1 is provided with an adjustment component 4 and an installation component 5 at the adjustment groove 2 and adjustment groove 3 respectively. The cross section of the guardrail 1 is an "L" shaped structure, and a connecting block 6 is welded at one corner of the guardrail 1.

[0021] The outer wall of the connecting block 6 at one end of the guardrail 1 is provided with equally spaced connecting grooves 7, and the outer wall of the connecting block 6 at the other end of the guardrail 1 is provided with protrusions 8 that are adapted to the connecting grooves 7. The protrusions 8 on the connecting block 6 at one end of the guardrail 1 are overlapped with the connecting grooves 7, and the pin is inserted into the pin hole to combine and connect multiple sets of guardrail 1. This makes it easier to extend the guardrail 1, easier to assemble, easier to use, and improves the range of action of the guardrail 1.

[0022] The protrusions 8 at both ends of the guardrail 1 and the center of the connecting groove 7 are provided with pin holes, and a pin is inserted into the pin holes;

[0023] The mounting assembly 5 includes an adjusting rod 12 that is slidably connected to the inner wall of the adjusting groove 3, a mounting ring 13 installed on the outer wall of the bottom end of the adjusting rod 12, and mounting holes that are equally spaced in the mounting ring 13. The guardrail 1 is installed on the ground through the mounting holes on the mounting ring 13, which facilitates installation.

[0024] The adjustment assembly 4 includes a positioning ring 9, an adjustment rod 10 welded to the center of both ends of the positioning ring 9, and an anti-slip protrusion 11 provided on the outer wall of the positioning ring 9.

[0025] The outer wall of the guardrail 1 is provided with fixing protrusions 16 at the adjustment groove 1 2 and adjustment groove 2 3 respectively. The outer wall of the fixing protrusions 16 of the guardrail 1 and the outer wall of the adjustment rod 1 10 and adjustment rod 2 12 are provided with fixing holes 17 distributed at equal intervals. The positioning ring 9 and the mounting ring 13 respectively drive the adjustment rod 1 10 and adjustment rod 2 12 to extend from the adjustment groove 1 2 and adjustment groove 2 3, thereby adjusting the overall length and height of the guardrail 1. After the adjustment is completed, the fixing screws 18 are screwed into the fixing holes 17 of the fixing protrusions 16 to fix the guardrail 1, adjustment rod 1 10 and adjustment rod 2 12, so as to facilitate the adjustment of length and height.

[0026] The outer walls of both the first adjusting rod 10 and the second adjusting rod 12 are welded with positioning protrusions 15, and the guardrail 1 is provided with positioning grooves 14 at the first adjusting groove 2 and the second adjusting groove 3. The positioning protrusions 15 are slidably connected in the positioning grooves 14. The first adjusting rod 10 and the second adjusting rod 12 are slidably connected in the first adjusting groove 2, the second adjusting groove 3 and the positioning groove 14 through the positioning protrusions 15, which facilitates adjustment and prevents rotation.

[0027] The outer wall of the guardrail 1 is threaded with a fixing screw 18 in the fixing hole 17, and one end of the fixing screw 18 is located in the adjusting rod 10 and the adjusting rod 2 12.

[0028] Working principle: In use, remove the fixing screw 18 from the fixing hole 17 of the fixing protrusion 16 according to the required length and height. The positioning ring 9 and the mounting ring 13 then drive the adjusting rod 10 and adjusting rod 12 to extend from the adjusting groove 2 and adjusting groove 3 respectively, adjusting the overall length and height of the guardrail 1. After adjustment, screw the fixing screw 18 into the fixing hole 17 of the fixing protrusion 16 to fix the guardrail 1, adjusting rod 10, and adjusting rod 12, facilitating length and height adjustment. The mounting holes on ring 13 allow the guardrail 1 to be installed on the ground, facilitating installation. When multiple sets of guardrail 1 are combined, the protrusion 8 on the connecting block 6 at one end of the guardrail 1 overlaps with the connecting groove 7, and the pin is inserted into the pin hole to connect multiple sets of guardrail 1. This facilitates the extension of the guardrail 1, makes it easier to assemble and use, and increases the effective range of the guardrail 1. Adjusting rod 10 and adjusting rod 2 12 are slidably connected in adjusting groove 1 2, adjusting groove 2 3 and positioning groove 14 through positioning protrusion 15, facilitating adjustment and preventing rotation.
