The support column 1 1 and the support column 2 3 are connected together through the fixing frame 2, thereby enhancing the overall structural stability of the entire storage rack, forming a solid whole between the various components, capable of withstanding greater weight and external force impact, and improving the service life of the storage rack.

[0037] A pull rod 19 is fixed to the front side of the placement plate 8, and an anti-slip sleeve 20 is fixed to the outside of the pull rod 19. A slide groove 21 is opened above the placement plate 8, and a fixed block 22 is slidingly provided inside the slide groove 21. A support plate 1 23 is fixed above the fixed block 22, and an electric rotating shaft 1 26 is fixed to the inner side of the upper part of the support plate 1 23. A support plate 2 25 is fixed above the electric rotating shaft 1 26, and an electric rotating shaft 2 27 is fixed to the inner side of the support plate 25. A placement box 24 is fixed to the inner side of the electric rotating shaft 27. When materials need to be taken, materials at high places are usually not easy to take. By pulling the pull rod 19, the fixed block 22 slides in the slide groove 21, and then the placement box 24 slides. Through the cooperation of the electric rotating shaft 1 26 and the electric rotating shaft 2 27, the placement box 24 is lowered for more convenient taking.

[0038] The working principle and process of a storage rack for building materials:

[0039] The storage rack is equipped with a universal wheel 6, which is installed on the lower end surface of the fixed plate 5, and the fixed plate 5 is connected to the support column 1 through the support frame 4. When the storage rack needs to be moved, the staff can push the storage rack, and the universal wheel 6 will roll accordingly, thereby realizing the flexible movement of the entire storage rack in the workplace to meet the needs of different building material storage locations. A square groove 16 is opened inside the support column 2 3 of the storage rack, and a motor 12 is fixed on the upper end of the square groove 16. When the height of the placement plate 8 needs to be adjusted, the motor 12 is started. After the motor 12 is started, its lower end surface is fixed The connected screw rod 13 will rotate accordingly, because the other end of the screw rod 13 is fixed with a rotating shaft 15, and the rotating shaft 15 can ensure the stable rotation of the screw rod 13. The outer spiral of the screw rod 13 is provided with a nut 14. When the screw rod 13 rotates, according to the principle of spiral transmission, the nut 14 will make a linear motion along the screw rod 13. The front end face of the nut 14 is fixed with a connecting block 10. The right end face of the connecting block 10 is slidably connected to the positioning block 7 through the positioning groove 11, and the positioning block 7 is fixed to the left end face of the placement plate 8. Therefore, when the nut 14 moves, it will drive the connecting block 10 to move, and then The positioning block 7 drives the placement plate 8 to be lifted and lowered. At the same time, a slider 18 is fixed to the front end surface of the connecting block 10, and a slide rail 17 is fixed inside the support column 1. The slider 18 slides in the slide rail 17, which further ensures the stability of the placement plate 8 during the lifting process. When the placement plate 8 is adjusted to a suitable height, the staff can hold the handle 9 on the front end surface of the placement plate 8 to place the building materials on the placement plate 8. Since the positioning block 7 slides in the positioning groove 11, the placement plate 8 can carry the building materials relatively stably. When the building materials on the placement plate 8 need to be taken, Hold the handle 9 and, according to actual needs, if the height of the placement plate 8 needs to be adjusted, the above-mentioned placement plate 8 lifting and lowering control steps can be repeated to adjust the placement plate 8 to a height that is convenient for taking building materials, and then take the building materials out of the placement plate 8 to serve as a storage rack for building materials. When materials need to be taken, materials at high places are usually not easy to take. By pulling the pull rod 19, the fixed block 22 slides in the slide groove 21, and then the placement box 24 slides, and the electric rotating shaft 1 26 and the electric rotating shaft 2 27 cooperate to lower the placement box 24 for more convenient taking.
