[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a telescopic and adjustable aluminum guardrail, including a lower crossbar 1 and an upper crossbar 2. A first U-shaped seat 3 is fixedly connected to the top of the lower crossbar 1 at equal intervals. An aluminum alloy sleeve 4 is rotatably connected inside each of the first U-shaped seats 3, allowing the sleeves to rotate within the seats for easy folding. A second U-shaped seat 5 is fixedly connected to the bottom of the upper crossbar 2 at equal intervals. An aluminum alloy telescopic rod 6 is rotatably connected inside each of the second U-shaped seats 5, allowing for easy folding. The bottom of the telescopic rod 6 extends into the aluminum alloy sleeve 4, facilitating telescopic adjustment and thus achieving the purpose of adjusting the height of the guardrail. A baffle 13 is fixedly connected to the bottom of the aluminum alloy telescopic rod 6 and inside the aluminum alloy sleeve 4. The baffle 13 is slidably connected to the inside of the aluminum alloy sleeve 4, preventing the aluminum alloy telescopic rod 6 from sliding out of the aluminum alloy sleeve 4. Limiting screws 14 are threadedly connected to the outer sides of the tops of the two aluminum alloy sleeves 4 at both ends. One end of each limiting screw 14 extends into the inside of the aluminum alloy sleeve 4 and abuts against the outer side of the aluminum alloy telescopic rod 6, better fixing the position of the aluminum alloy telescopic rod 6 after telescopic adjustment.

[0027] Reference Figure 2 and Figure 3 In one aspect of this embodiment, a protrusion 7 is fixedly connected to one end of both the lower crossbar 1 and the upper crossbar 2, and a groove 8 that cooperates with the protrusion 7 is provided at the other end of both the lower crossbar 1 and the upper crossbar 2. The cooperation between the protrusion 7 and the groove 8 facilitates the connection and use of multiple lower crossbars 1 and upper crossbars 2. A fixing hole 9 is provided at the top of the lower crossbar 1 and between two adjacent first U-shaped seats 3. The fixing hole 9 allows for better fixation and installation of the equipment in a designated position.

[0028] Reference Figure 3 and Figure 5 In one aspect of this embodiment, a horizontal plate 10 is fixedly connected to the outer side of the bottom of an aluminum alloy sleeve 4 located at the end. A fastening screw 11 is threadedly connected to the top of the horizontal plate 10. A threaded hole 12 is provided at the top of the lower crossbar 1 and directly below the horizontal plate 10. The bottom of the fastening screw 11 extends through the horizontal plate 10 into the threaded hole 12 and is threadedly connected to the threaded hole 12. When the aluminum alloy sleeve 4 is in a vertical state, i.e., when the guardrail is unfolded for use, the fastening screw 11 is used to thread it into the threaded hole 12, thereby fixing the aluminum alloy sleeve 4 and ensuring that the aluminum alloy sleeve 4 is always in a vertical state for convenient use.

[0029] Working principle: In use, first unfold the upper crossbar 2, aluminum alloy sleeve 4, and aluminum alloy telescopic rod 6, as follows: Figure 1 As shown, the fastening screw 11 is positioned directly above the threaded hole 12. Tightening the bottom of the fastening screw 11 into the threaded hole 12 secures the upper crossbar 2, aluminum alloy sleeve 4, and aluminum alloy telescopic rod 6. Then, the lower crossbar 1 is fixed in the designated position via the fixing hole 9 for use.

[0030] When it is necessary to increase the length of the guardrail, the protrusion 7 and the groove 8 can be used to connect multiple lower horizontal bars 1 and upper horizontal bars 2.

[0031] When adjusting the height of the guardrail, loosen the limiting screw 14 so that one end no longer touches the aluminum alloy telescopic rod 6. Then, lift the upper crossbar 2 to adjust the extension length of the aluminum alloy telescopic rod 6 inside the aluminum alloy sleeve 4, thereby adjusting the height of the guardrail. After adjusting the height, tighten the limiting screw 14 again so that one end touches the outside of the aluminum alloy telescopic rod 6, thus fixing its height position.

[0032] When the guardrail needs to be carried and moved, first remove the mounting piece inside the fixing hole 9, then tighten the fastening screw 11 to disengage its bottom from the threaded hole 12. Next, adjust the extension length of the aluminum alloy telescopic rod 6 inside the aluminum alloy sleeve 4 according to the above operation to minimize its extension length. Then, rotate the upper crossbar 2, the aluminum alloy sleeve 4, and the aluminum alloy telescopic rod 6 to fold them as shown. Figure 5 As shown in the image, the entire device can be easily moved and carried.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
