[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] 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.

[0022] Example 1: Reference Figure 1-4The safety protection equipment for highway construction shown includes a first column 1 and a second column 2, which together form the support frame of the equipment, providing stable vertical support for the overall structure and ensuring that the protective equipment is not easily tipped over in the construction environment. A pair of sliding rods 6 are fixedly connected to the side of the first column 1, and a pair of sliding cylinders 7 adapted to the sliding rods 6 are fixedly connected to the side of the second column 2. The sliding rods 6 can slide along the inside of the sliding cylinders 7, realizing the adjustment of the distance between the first column 1 and the second column 2 to adapt to the protection needs of construction areas of different widths. Multiple adjustable protective components are arranged between the pair of sliding rods 6; the adjustable protective components include a placement frame 8 fixedly connected to the outside of the sliding rods 6, used to provide installation space for the fixing block 11 and restrict its position. The fixing block 11 is arranged inside the placement frame 8, serving to connect the first baffle 10 and the fixing block 11. The function of the frame 8 is to provide a first baffle 10 between a pair of fixed blocks 11 in the same column. The first baffle 10 is fixedly connected to the fixed blocks 11 and can prevent external personnel or objects from entering the construction area, thus providing basic protection. A second baffle 18 is hinged to the outer side of the first baffle 10. The second baffle 18 can rotate around the hinge and can be opened when temporary passage or material handling is required, increasing the flexibility of equipment use. A splicing assembly is provided on the outer side of the second column 2. The splicing assembly includes a rotating rod 3 that is rotatably connected to the outer side of the second column 2. The rotating rod 3 can rotate freely for easy adjustment. The threaded rod 4 is fixedly connected to one end of the rotating rod 3. A threaded hole 5 that matches the threaded rod 4 is opened on the outer side of the first column 1. When it is necessary to extend the length of the protective equipment, the threaded rod 4 of the adjacent equipment is screwed into the threaded hole 5 to realize the quick splicing and fixing of multiple equipment. Recessed grooves are opened on both sides of the fixing block 11 to provide installation positions for the protrusion 13. The protrusion 13 is set in the recessed groove. The protrusion 13 is made of rubber block and has a certain elasticity. The inner wall side of the placement frame 8 is provided with a slot 16 that matches the protrusion 13. When the fixing block 11 is placed into the placement frame 8, the protrusion 13 The fixing block 11 is inserted into the slot 16 to enhance the stability of the connection between the fixing block 11 and the placement frame 8, and to prevent the fixing block 11 from loosening and falling off during use. The outer sides of the first baffle 10 and the second baffle 18 are both provided with grooves 17 for placing magnetic plates 14. The magnetic plates 14 are set in the grooves 17 and can attract magnetic warning signs, which facilitates the installation and replacement of warning signs and improves the warning effect in the construction area. The bottom ends of the first column 1 and the second column 2 are both fixedly connected to the base plate 12, which increases the contact area between the column and the ground, reduces the pressure of the equipment on the ground, and makes the column more stable on the ground.

[0023] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment also proposes that a locking block 15 is fixedly connected to the outer side of the sliding rod 6. The locking block 15 can restrict the relative rotation between the sliding rod 6 and the sliding cylinder 7, ensuring that the two maintain the same direction when moving axially. A guide groove adapted to the locking block 15 is provided on the outer side of the sliding cylinder 7. The guide groove provides a moving path for the locking block 15, ensuring that the sliding rod 6 slides stably along a fixed trajectory. A bolt 9 is provided on the outer side of the sliding cylinder 7. The bolt 9 can realize the relative fixation of the sliding rod 6 and the sliding cylinder 7. A threaded groove adapted to the bolt 9 is provided on the inner side of both the sliding cylinder 7 and the sliding rod 6. The threaded groove can enhance the stability of the connection through the threaded engagement with the bolt 9, preventing the relative displacement of the sliding rod 6 and the sliding cylinder 7 when subjected to force.

[0024] The working principle of this utility model is as follows: Dragging the first column 1 drives the sliding rod 6 to slide the locking block 15 along the sliding cylinder 7. Adjusting the distance between the first column 1 and the second column 2, the bolt 9 is used to connect with the corresponding threaded groove to limit and fix the sliding rod 6 and the sliding cylinder 7. Dragging the baffle 10 drives the fixing block 11 to slide into the corresponding placement frame 8. The inner wall of the placement frame 8 presses the protrusion 13, which deforms until it slides into the locking groove 16 and restores its shape to engage with the locking groove 16, thus realizing the installation of the baffle 10 and providing protection for the construction area. Dragging the stacked baffles 10 together can separate them, and a pair of magnetic plates 14 attract each other, thus unfolding a pair of baffles 10. Under appropriate circumstances, there is no need to install new baffles 10, making the operation simple.

[0025] 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.
