[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Example 1:

[0023] like Figures 1 to 4 As shown, a progressive guardrail facility for controlling the entrance of an urban tunnel includes a base plate 1, a main rod 2 fixedly connected to the base plate 1, a secondary rod 3 fixedly connected to the main rod 2, one end of the secondary rod 3 fixedly connected to the base plate 1, a reflective sticker 4 provided on the secondary rod 3, a receiving cavity 7 provided inside the base plate 1, a support frame 5 fixedly connected to the base plate 1, a threaded rod 6 rotatably connected to the support frame 5, the lower end of the threaded rod 6 rotatably connected to the base plate 1, a horizontal plate 8 threadedly connected to the threaded rod 6, the horizontal plate 8 slidably connected inside the receiving cavity 7, a sliding rod 9 fixedly connected to one end of the horizontal plate 8, and a foot plate 10 fixedly connected to the lower end of the sliding rod 9.

[0024] Furthermore, in this embodiment, by rotating the threaded rod 6, the horizontal plate 8 is driven to slide up and down in the receiving cavity 7 through the threaded transmission. The horizontal plate 8 drives the sliding rod 9 and the foot plate 10 to rise and fall, realizing the switching between facility support and movement states, which facilitates deployment and relocation.

[0025] Specifically, a connecting bracket 11 is provided on one side of the main rod 2, and a bolt 12 is threaded onto the connecting bracket 11. A connecting block 13 is provided on the other side of the main rod 2, and an insertion hole 14 is provided on the connecting block 13.

[0026] In this embodiment, the connecting block 13 is inserted into the connecting frame 11 of another main rod 2, and the bolt 12 is turned so that it passes through the threaded hole of the connecting frame 11 and is inserted into the insertion hole 14, so as to realize the splicing of multiple sets of railing facilities and extend the length of the facilities.

[0027] Specifically, the bottom of the base plate 1 is equipped with casters 15, and there are four sets of casters 15.

[0028] As a preferred implementation, when the footboard 10 is raised, the casters 15 contact the ground and rotate to move the facility, which facilitates the movement of the facility and reduces manual handling.

[0029] Specifically, there are two sets of slide rods 9, which are located at both ends of the horizontal plate 8.

[0030] In this embodiment, when the horizontal plate 8 moves, it drives the two sets of sliding rods 9 to slide synchronously, ensuring that the foot plate 10 rises and falls smoothly and improving stability.

[0031] Specifically, the sub-pole 3 has several sets, and the reflective stickers 4 have several sets, with the reflective stickers 4 respectively located on both sides of the sub-pole 3.

[0032] With this setup, the secondary pole 3 and the main pole 2 together form the guardrail structure, and the reflective sticker 4 reflects light to form a protective barrier, improving the warning effect for vehicles at night.

[0033] Specifically, the foot plate 10 is provided with two sets of fixing holes.

[0034] The stability of the facility is further enhanced by inserting rivets or placing counterweights in the fixing holes.

[0035] Specifically, the slide rod 9 is slidably connected to the base plate 1.

[0036] Working principle: In use, the device is first moved to the entrance of the city tunnel by rotating the four sets of casters 15. Then, the threaded rod 6 is turned on the support frame 5 and the base plate 1. The threaded rod 6 drives the horizontal plate 8 to slide in the receiving cavity 7 through the threaded connection. At the same time, the horizontal plate 8 drives the two sets of sliding rods 9 to slide downward on the base plate 1. The sliding rods 9 drive the foot plate 10 to move. When the foot plate 10 is in contact with the ground, it can support the device and improve its stability. In addition, rivets can be inserted through the fixing holes on the foot plate 10 or counterweights can be placed on the foot plate 10 to further improve stability.

[0037] When the device needs to be moved later, the threaded rod 6 is turned in the opposite direction to rotate and drive the slide rod 9 to rise so that the foot plate 10 is lifted off the ground. Then, the device is moved by the rotation of the four sets of universal wheels 15, thereby reducing the physical effort consumed by the user in carrying it and improving the transfer efficiency.

[0038] When multiple connections are needed, simply place the connecting block 13 on one side of the other device onto the connecting bracket 11 on one side of the fixed main rod 2, and then turn the bolt 12. The bolt 12 moves downward on the connecting bracket 11 through the threaded connection. When the bolt 12 passes through the insertion hole 14 on the connecting block 13, the other main rod 2 is fixed. Thus, multiple main rods 2 can be spliced ​​together to form a whole according to the layout length. Reflective stickers 4 are provided on both sides of the auxiliary rod 3 to alert passing vehicles.

[0039] 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.
