[0024] Reference Figure 1-4A super-strong load-bearing dense bookshelf column includes a bottom plate 1 and a top plate 2. The top plate 2 is arranged above the bottom plate 1. Two groups of first columns 3 and two groups of second columns 4 are fixedly connected between the bottom plate 1 and the top plate 2. A crossbeam 5 is inserted between the two groups of first columns 3. A support plate A6 is fixedly welded to one side of the crossbeam 5. A support plate B7 is slidably connected to the inside of the support plate A6. A pull rod 8 is fixedly installed between one side of the first column 3 and the top of the support plate A6. A support rod 9 is fixedly installed between one side of the second column 4 and the bottom of the support plate A6. A fixing sleeve 10 is provided on the outside of the support rod 9. A reinforcing rod 11 is fixedly installed on one side of the fixing sleeve 10. The end is fixedly connected to one side of the second column 4, and an electric push rod 12 is fixedly installed on one side of the second column 4. The output end of the electric push rod 12 is fixedly connected to the ear plate 13. One side of the first column 3 and the second column 4 is fixedly connected to a slide rail A14. The inner sliding connection of the slide rail A14 is connected to a slider 15. One side of the slider 15 is fixedly connected to a rotating seat 16. The ear plate 13 and the rotating seat 16 are rotatably connected through a rotating shaft. One side of the first column 3 and the second column 4 is fixedly connected to a fixed block 17. A connecting rod A18 is movably connected between the slider 15 and the fixed block 17. A connecting rod B19 is movably installed at the center position of the connecting rod A18. A tensioning assembly is provided between the support plates A6 and B7. When in use, first, when the book is placed on the support plates A6 and B7, a downward pressure is generated on the first column 3 and the second column 4, so that the pull rod 8 pulls the distal end of the support plate A6 to generate an oblique upward pulling force, thereby improving the bearing capacity of the first column 3 and the second column 4 itself. At the same time, an oblique upward supporting force is provided from the bottom end of the support plate A6 through the support rod 9 to increase the bearing weight of the first column 3 and the second column 4. At the same time, the support rod 9 is strengthened and fixed by the reinforcing rod 11, so that the pressure borne by the support rod 9 can be shared, and a triangular structure is formed between the support rod 9 and the reinforcing rod 11. In order to further improve the overall firmness of the first column 3 and the second column 4, by installing a connecting rod A18 and a connecting rod B19 between the first column 3 and the second column 4, starting the electric push rod 12 to push the connecting rod A18 and thereby drive the connecting rod B19, and utilizing the connecting rod A18 and the connecting rod B19 to push the first column 3 to move, thereby realizing the relative movement of the pallet A6 and the pallet B7, utilizing the spring 20 to connect the pallet A6 and the pallet B7, cooperating with the electric push rod 12 to adjust the distance between the two groups of first columns 3 and second columns 4, the spacing between the bookshelves can be flexibly adjusted, thereby expanding the usable area of the bookshelves as needed, and improving the practicality and space utilization of the compact shelving.
[0025] Specifically, the first column 3 and the second column 4 are both arranged in an I-shape, and the first column 3 and the second column 4 are made of alloy steel material. The two parallel flanges of the I-shaped structure can provide good lateral stability, so that the first column 3 and the second column 4 have a higher bending resistance when bearing vertical loads. The high strength and hardness of the alloy steel material enable the columns to withstand greater loads.
[0026] Specifically, the cross-section of the structure formed by the support rods 9 and the reinforcing rods 11 is triangular. The triangular structure can evenly distribute the load and reduce local stress concentration, thereby improving the load-bearing capacity and durability of the bookshelf.
[0027] Specifically, both ends of the connecting rod A18 and the connecting rod B19 are provided with through holes, and pins are connected in the through holes, so that all the movable connection structures are simple and stable, easy to install and do not affect use.
[0028] Specifically, the internal linear array of pallet A6 has multiple groups of springs 20, and both ends of the springs 20 are welded to one side of the interior of pallet A6 and pallet B7 is located on one side of the interior of pallet A6. The springs 20 are respectively welded to one side of the interior of pallet A6 and pallet B7 is located on one side of the interior of pallet A6. When the electric push rod 12 is actuated, auxiliary thrust is provided to facilitate the adjustment of the distance between the first column 3 and the second column 4.
[0029] Specifically, the tensioning assembly includes a wire reel 21, a wire drum is provided inside the wire reel 21, and a plurality of pull wires 22 are wound around the outer surface of the wire drum. A plurality of through openings are provided on the wire reel 21, and each pull wire 22 extends from a corresponding through opening. By arranging the wire reel 21 to tighten the bottom plate 1 and the top plate 2, the strength of the bookshelf can be improved, and the center of gravity shift caused by placing books can be avoided, which may lead to the collapse of the bookshelf.
[0030] Specifically, fixing rings 23 connected to the pull wire 22 are fixedly installed on the bottom and top of the relative outer sides of the bottom plate 1 and the top plate 2, which can ensure that the pull wire 22 is effectively fixed in the vertical direction of the bookshelf. The fixing rings 23 have good stability and load-bearing capacity, and can withstand the tension generated by the pull wire 22, thereby ensuring the stability and safety of the bookshelf.
[0031] Specifically, slide rails B24 are fixedly installed at both ends of the top of the base plate 1 and the bottom of the top plate 2, and the first column 3 and the second column 4 are slidably connected to the surface of the slide rail B24. The design of the slide rail B24 can adopt a linear guide rail, which can provide high-precision linear motion and has a high load capacity.
[0032] Working principle: When in use, first, when the book is placed on the pallet A6 and the pallet B7, a downward pressure will be generated on the first column 3 and the second column 4, so that the pull rod 8 pulls the far end of the pallet A6, generating an oblique upward pulling force, thereby improving the bearing capacity of the first column 3 and the second column 4 itself, and at the same time, through the support rod 9, an oblique upward supporting force is provided from the bottom end of the pallet A6 to increase the bearing weight of the first column 3 and the second column 4, and at the same time, the support rod 9 is strengthened and fixed by the reinforcing rod 11, so that the pressure borne by the support rod 9 can be shared, and the support rod 9 and the reinforcing rod 11 form a triangular structure with each other, thereby further improving the overall firmness of the first column 3 and the second column 4. A connecting rod A18 and a connecting rod B19 are installed between the first column 3 and the second column 4, and the electric push rod 12 is started to push the connecting rod A18, thereby driving the connecting rod B19. The connecting rod A18 and the connecting rod B19 are used to push the first column 3 to move, thereby realizing the relative movement of the pallet A6 and the pallet B7. The pallet A6 and the pallet B7 are connected by the spring 20, and the distance between the two groups of first columns 3 and second columns 4 is adjusted in conjunction with the electric push rod 12. The spacing between the bookshelves can be flexibly adjusted, thereby expanding the usable area of the bookshelves as needed, thereby improving the practicality and space utilization of the compact shelving. By setting a reel 21 to tighten the bottom plate 1 and the top plate 2, the strength of the bookshelf can be improved, and the center of gravity shift caused by placing books can be avoided, which may lead to the collapse of the bookshelf.
