Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Example 1: Reference Figure 1-4The temporary guardrail shown includes a base plate 1 and a fixing plate 2. Multiple first mounting brackets 3 are fixedly connected to the bottom of the base plate 1. The first mounting brackets 3 support and fix the fixing cylinder 4, allowing the fixing cylinder 4 to be stably installed on the base plate 1, providing a foundation for subsequent connection with other components. The multiple first mounting brackets 3 ensure the stability of the base plate 1 when in contact with the ground, preventing the base plate 1 from tilting or shaking. Multiple second mounting brackets 11 are fixedly connected to the top of the fixed plate 2. These brackets support and fix the fixing rods 5, ensuring their stability on the top of the fixed plate 2 and providing support points for the temporary fence's connection structure. A fixing cylinder 4 is rotatably connected to the inner wall of the first mounting bracket 3 via a pivot. The fixing cylinder 4 can rotate around the pivot, facilitating connection or disassembly with the fixing rods 5, enabling flexible connections between different components of the temporary fence and making installation and adjustment more flexible. A fixing rod 5 is rotatably connected to the inner wall of the second mounting bracket 11 via a pivot. The fixing rod 5 can rotate on the second mounting bracket 11 to cooperate with the fixing cylinder 4, allowing for the splicing of different parts of the temporary fence and enabling flexible assembly according to the needs of the construction site. A positioning frame 9 is fixedly connected to the outer side of one of the fixing cylinders 4. The positioning frame 9 assists in positioning the trapezoidal block 10, fixing its position on the fixing cylinder 4, thereby ensuring that the trapezoidal block 10 can accurately cooperate with other components, playing a crucial role in... The positioning frame 9 has a fixed trapezoidal block 10 on its outer side for positioning and guiding. The trapezoidal block 10 is used to cooperate with the positioning component to lock different parts of the temporary guardrail, preventing the fixed cylinder 4 and the fixed rod 5 from accidentally separating during use, thus enhancing the stability of the temporary guardrail. The trapezoidal block 10 has a slot 18 on its outer side for cooperating with the slot block 17. The engagement of the two further ensures the firmness of the temporary guardrail connection and prevents the connection from loosening. A pair of positioning plates 6 are fixedly connected to the bottom of the fixing plate 2. The positioning plates 6 serve to fix and support the positioning component, ensuring that the positioning component is stable at the bottom of the fixing plate 2 and that the positioning component can accurately cooperate with the trapezoidal block 10. A positioning component is set between the pair of positioning plates 6. The positioning component includes a fixed frame 8 fixedly connected to the bottom of the positioning plate 6. The fixed frame 8 provides a sliding track for the L-shaped block 7, ensuring that the L-shaped block 7 slides in a specific direction and can accurately cooperate with the slot 18 on the trapezoidal block 10. An L-shaped block 7 is slidably connected to the inner wall of the fixed frame 8. The L-shaped block 7 can slide within the fixed frame 8, and the sliding action enables the locking and unlocking of the locking block 17 and the locking groove 18, thereby controlling the locking and unlocking of the temporary guardrail connection and facilitating the installation and disassembly of the temporary guardrail. A spring 12 is fixedly connected to the top of the L-shaped block 7. The end of the spring 12 away from the L-shaped block 7 is fixedly connected to the fixed plate 2. The spring 12 provides an upward elastic force to the L-shaped block 7, ensuring that the locking block 17 and the locking groove 18 are in the locked state when no external force is applied, thus ensuring the stability of the temporary guardrail connection.The bottom of the L-shaped block 7 is fixedly connected to a locking block 17 that matches the slot 18. When the locking block 17 engages with the slot 18, it can effectively prevent relative rotation or separation between the fixing cylinder 4 and the fixing rod 5, ensuring the safety and stability of the temporary guardrail during use.

[0019] Example 2: Reference Figure 1-4 Based on the same concept as in Embodiment 1 above, this embodiment also proposes that the fixing rod 5 is slidably connected to the inner wall side of the fixing cylinder 4, and a slot is provided on the inner side of the fixing cylinder 4. The fixing rod 5 can slide smoothly on the inner wall side of the fixing cylinder 4, allowing the two to move flexibly relative to each other. The slot provides a spatial basis for the installation or operation of subsequent related components. A groove 19 is provided on the inner side of the base plate 1, and a rotating rod 20 is rotatably connected to the inner wall side of the groove 19. The groove 19 provides space for the rotating rod 20 to rotate, allowing the rotating rod 20 to rotate freely around its axis within the groove 19. Slide grooves 16 are provided on both sides of the base plate 1, and both ends of the rotating rod 20 extend into the slide grooves 16. Threaded rods 14 are fixedly connected to both ends of the rotating rod 20. An extension plate 15 is threadedly connected to the outer side of the threaded rod 14, and the extension plate 15 is slidably connected to the slide groove 16. A threaded hole 13 is provided on the outer side of the extension plate 15. When the rotating rod 20 rotates, the threaded rod 14 fixedly connected to its two ends rotates accordingly. Since the threaded rod 14 is threadedly connected to the extension plate 15, and the extension plate 15 can slide within the slide groove 16, the rotation of the threaded rod 14 can drive the extension plate 15 to slide along both sides of the base plate 1 within the slide groove 16, thereby adjusting the position of the extension plate 15. The threaded hole 13 can be used to connect other components. A bolt 21 is provided on the outer side of one of the fixing cylinders 4, and threaded grooves matching the bolt 21 are provided on the inner sides of both the fixing cylinder 4 and the fixing rod 5. When it is necessary to fix the relative position of the fixing rod 5 and the fixing cylinder 4, the bolt 21 is screwed into the threaded groove that matches the inner side of the fixing cylinder 4 and the fixing rod 5. Through the tightening action of the bolt 21, the fixing rod 5 and the fixing cylinder 4 can be firmly connected to prevent them from sliding relative to each other.

[0020] The working principle of this utility model is as follows: Dragging the fixed plate 2 causes the fixed cylinder 4 to deflect through multiple first mounting brackets 3, so that the fixed cylinder 4 and the fixed rod 5 are in a vertical state. During the movement, the fixed plate 2 moves through the positioning plate 6, the fixed frame 8, and the L-shaped block 7. The inclined surface of the trapezoidal block 10 presses the locking block 17 until the L-shaped block 7 is reset under the action of the spring 12, so that the locking block 17 is engaged with the slot 18, and the guardrail installation is completed. Twisting the rotating rod 20 drives the threaded rod 14 to rotate, so that the extension plate 15 slides outward along the slide groove 16, increasing the support surface of the base plate 1 in contact with the ground and improving stability. Unscrewing the bolt 21, dragging the fixed plate 2, the first mounting bracket 3, and the fixed cylinder 4 upward, increases the overall height of the guardrail. The bolt 21 is used to limit and fix the fixed cylinder 4. Dragging the L-shaped block 7 upward releases the engagement of the locking block 17 with the slot 18. Dragging the fixed plate 2 diagonally downward folds the fixed plate 2 and the base plate 1.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
