[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a foldable shelving unit for construction, including a fixed frame 1. The inner wall of the fixed frame 1 has a guide groove 8, a support plate 2 slidably connected to the inner wall of the guide groove 8, and a protective plate 3 slidably connected to the inner wall of the guide groove 8. A sliding groove 15 is provided on one side of the support plate 2, a slider 12 slidably connected to the inner wall of the sliding groove 15, and a positioning post 13 fixedly connected to the inner wall of the sliding groove 15. A handle 10 is rotatably connected to one side of the fixed frame 1, and a threaded rod 11 is rotatably connected to the inner wall of the sliding groove 15. The threaded rod 11 passes through the inner walls of the positioning post 13 and the slider 12. The end of the threaded rod 11 near the handle 10 is fixedly connected to the surface of the handle 10, and the surface of the threaded rod 11 is threadedly connected to the inner wall of the slider 12. The fixed frame 1 and the protective plate 3... Both sides of the support plate 2 and the protective plate 3 are provided with sliding grooves 15. The sliding grooves 15 on both sides of the support plate 2 and the protective plate 3 are also slidably connected to sliders 12. The sliding grooves 15 on both sides of the support plate 2 and the protective plate 3 are also fixedly connected to positioning posts 13. The surfaces of the positioning posts 13 on both sides of the support plate 2 and the protective plate 3 are rotatably connected to connecting rods 21. The ends of the two connecting rods 21 away from the positioning posts 13 are rotatably connected to sliders 12 on both sides of the support plate 2. The surfaces of the sliders 12 on both sides of the support plate 2 and the protective plate 3 are rotatably connected to connecting rods 14. The ends of the two connecting rods 14 away from the sliders 12 are rotatably connected to positioning posts 13 on both sides of the support plate 2. The surfaces of the connecting rods 14 are fixedly connected to rotating shafts 16. The surfaces of the rotating shafts 16 are rotatably connected to the interior of connecting rods 21.

[0025] When it is necessary to adjust the height of the support plate 2 and the protective plate 3, the handle 10 is turned to rotate the slide 15. When the slide 15 rotates, the slider 12 on one side of the support plate 2 slides along the slide 15 on one side of the support plate 2. When the slider 12 on one side of the support plate 2 slides, it drives one end of the two connecting rods 21 to slide and rotate along the slider 12 on one side of the support plate 2. At the same time, when the two connecting rods 21 rotate, they drive the two rotating shafts 16 and the connecting rod 14 to slide upward. This causes the two connecting rods 21 and the two connecting rods 14 to push the support plate 2 and the protective plate 3 upward respectively, thereby completing the adjustment of the distance between the support plate 2 and the protective plate 3.

[0026] A fixed shaft 20 is fixedly connected to the surface of the fixed frame 1. An extension frame 7 is rotatably connected to the surface of the fixed shaft 20. A guide groove 9 is opened on the surface of the extension frame 7. A spring 19 is fixedly connected to the inner wall of the fixed frame 1. One end of the spring 19 away from the inner wall of the fixed frame 1 is fixedly connected to the surface of the extension frame 7. A fixed block 6 is fixedly connected to the surface of the protective plate 3.

[0027] When the protective plate 3 slides upward, it drives the fixing block 6 to slide upward. At this time, the fixing block 6 pushes the extension frame 7 to rotate along the fixing shaft 20. When the fixing shaft 20 rotates, it pulls the spring 19 to deform. Then, after the extension frame 7 rotates ninety degrees, the guide groove 2 9 and the guide groove 1 8 are connected. Then, when the protective plate 3 slides upward along the guide groove 1 8, it slides into the interior of the guide groove 2 9, thereby increasing the adjustment range of the support plate 2 and the protective plate 3. When adjusting the distance between the support plate 2 and the protective plate 3, the fixing block 6 pushes the extension frame 7 to rotate, thereby connecting the guide groove 1 8 and the guide groove 2 9. Thus, the distance between the support plate 2 and the protective plate 3 can be adjusted according to the height of the construction site. As the distance between the support plate 2 and the protective plate 3 increases, more tools and objects can be placed, thereby increasing the storage capacity of the shelf.

[0028] A protective rod 4 is fixedly connected to one side of the protective plate 3. A fixed post 18 is fixedly connected to the inner wall of the protective rod 4. A spring 17 is fixedly connected to the surface of the fixed post 18. A rotating shaft 16 is rotatably connected to the inner wall of the protective rod 4. The end of the spring 17 away from the fixed post 18 is fixedly connected to the inner wall of the rotating shaft 16. A protective cloth 5 is wrapped around the surface of the rotating shaft 16. The end of the protective cloth 5 near the rotating shaft 16 is fixedly connected to the surface of the rotating shaft 16. A pull rod 23 is fixedly connected to the end of the protective cloth 5 away from the rotating shaft 16. A clamping plate 22 is fixedly connected to the surface of the fixing frame 1. The clamping plate 22 is L-shaped.

[0029] By pulling the lever 23 downwards, the lever 23 causes one end of the protective cloth 5 to extend. As the protective cloth 5 extends, it pulls the rotating shaft 16 to rotate. When the rotating shaft 16 rotates, it causes the spring 17 to deform. When the lever 23 is pulled to one side of the pallet 22, the lever 23 is placed under the pallet 22 to restrict it and prevent it from resetting. By pulling the lever 23 to bring the protective cloth 5 to the bottom of the pallet 22, the tools and objects inside the shelf are protected, preventing dust from falling onto the surface of the tools and objects and preventing foreign objects from dripping onto the surface of the tools, thereby increasing the safety of the tools.

[0030] Working principle: When it is necessary to adjust the height of the support plate 2 and the protective plate 3, the handle 10 is turned to drive the slide groove 15 to rotate. When the slide groove 15 rotates, it drives the slider 12 on one side of the support plate 2 to slide along the slide groove 15 on one side of the support plate 2. When the slider 12 on one side of the support plate 2 slides, it drives one end of the two connecting rods 21 to slide and rotate along the slider 12 on one side of the support plate 2. At the same time, when the two connecting rods 21 rotate, they drive the two rotating shafts 16 and the connecting rod 14 to slide upward. This causes the two connecting rods 21 and the two connecting rods 14 to push the support plate 2 and the protective plate 3 upward respectively, thereby completing the adjustment of the distance between the support plate 2 and the protective plate 3.

[0031] When the protective plate 3 slides upward, it drives the fixing block 6 to slide upward. At this time, the fixing block 6 pushes the extension frame 7 to rotate along the fixing shaft 20. When the fixing shaft 20 rotates, it pulls the spring 19 to deform. Then, after the extension frame 7 rotates ninety degrees, the guide groove 2 9 and the guide groove 1 8 are connected. Then, when the protective plate 3 slides upward along the guide groove 1 8, it slides into the interior of the guide groove 2 9, thereby increasing the adjustment range of the support plate 2 and the protective plate 3. When adjusting the distance between the support plate 2 and the protective plate 3.

[0032] By pulling the lever 23 downwards, the lever 23 causes one end of the protective cloth 5 to extend. As the protective cloth 5 extends, it pulls the rotating shaft 16 to rotate. When the rotating shaft 16 rotates, it causes the spring 17 to deform. When the lever 23 is pulled to one side of the clamping plate 22, the lever 23 is placed under the clamping plate 22 to restrict the lever 23 and prevent it from resetting.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
