Detailed Implementation

[0017] 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.

[0018] Please see Figures 1-5 In this embodiment of the utility model, a traffic road protection device includes a flexible water-retaining bag 15 and a detachable outer shell. The water-retaining bag 15 is located inside the outer shell, and the material of the water-retaining bag 15 can be selected from TPU, PVC, PEVA, or rubber. The wall thickness of the water-retaining bag 15 is preferably 0.3-1.0 mm. It is worth noting that when the size of the water-filled barrier is larger, that is, when the volume of the water-retaining bag 15 is larger, its wall thickness should also be appropriately increased. The outer shell includes a base 10, a top cover 12, and a foldable square tube. 1. Multiple pads 11 are fixedly installed at the bottom of the base 10. The two ends of the square tube 1 are located inside the base 10 and the top cover 12, respectively. The bottom and top of the outer wall of the water storage bag 15 are fixedly connected with external threaded tubes 16 by heat fusion. The two external threaded tubes 16 are used as the water injection pipe and the drain pipe of the water storage bag 15, respectively. The outer wall of the base 10 and the top of the top cover 12 are both provided with through holes that are adapted to the external threaded tubes 16. The external threaded tubes 16 are threadedly connected to the plugs 20 after passing through the corresponding through holes.

[0019] Furthermore, the square tube 1 includes two first side plates 2, two second side plates 4, and four through rods 6. Both ends of the two first side plates 2 are fixedly connected with multiple first connecting ears 3 from top to bottom. Both ends of the two second side plates 4 are fixedly connected with multiple second connecting ears 5 from top to bottom. The first connecting ears 3 and the second connecting ears 5 are rotatably sleeved on the corresponding through rods 6. An opening groove 9 is opened at the corresponding position of the front wall of one of the first side plates 2 and the external threaded tube 16.

[0020] By adopting the above-mentioned solution, when not in use, the outer shell consisting of the top cover 12, the base 10, and the square tube 1 can be disassembled and stored separately. The square tube 1 is foldable, and the water storage bag 15 can be folded or rolled into the top cover 12 or the base 10 after the air is emptied. This greatly reduces the transportation space occupied by the water-filled bag. When in use, the base 10 and the top cover 12 are placed over the two ends of the unfolded square tube 1, the external threaded tube 16 is passed through the corresponding through hole, and the required amount of water is injected into the water storage bag 15. The operation is simple and convenient.

[0021] Specific combination Figure 1 , Figure 2 and Figure 5 In one embodiment of this utility model, positioning blocks 7 are fixedly sleeved on the outer wall of the through rod 6 near both ends. The first connecting ear 3 and the second connecting ear 5 are both located between the two positioning blocks 7. The base 10 and the top cover 12 are respectively provided with interconnected positioning grooves 13 and through holes 14 at the corresponding positions of each through rod 6. The positioning block 7 is located in the corresponding positioning groove 13. After the two ends of the through rod 6 pass through the corresponding through holes 14, they are respectively sleeved with a first nut 8 through external thread.

[0022] By cooperating with the positioning block 7 and the positioning groove 13, the through rod 6 can be positioned in the base 10 and the top cover 12. The shape of the positioning block 7 is preferably a regular polygonal prism to prevent the through rod 6 from rotating with the first nut 8 when the first nut 8 is tightened on the through rod 6. This makes it convenient to use the threaded engagement between the first nut 8 and the end of the through rod 6 to tighten the top cover 12 and the base 10 together to ensure the stability of the shell after assembly.

[0023] Specific combination Figure 4 and Figure 5 In one embodiment of the present invention, the outer wall of the external threaded tube 16 is provided with a plurality of inserts 17 arranged in a circular pattern, and the inner wall of the through hole and the corresponding position of each insert 17 are provided with slots 18, and the inserts 17 are located in the corresponding slots 18.

[0024] Furthermore, the externally threaded tube 16 is fitted with a hand-tightening nut 19 after passing through the corresponding through hole.

[0025] By engaging the insert 17 with the slot 18, the threaded tube 16 can be limited within the through hole to prevent it from rotating with the plug 20 when the plug 20 is being rotated on the threaded tube 16. Furthermore, by using the hand-tightening bolt 19, simply tightening the hand-tightening bolt 19 on the threaded tube 16 will lock the threaded tube 16 in the corresponding through hole, making the operation simple and convenient.

[0026] Although the present invention 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 invention should be included within the protection scope of the present invention.
