Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 4, an embodiment provided by the present utility model: a storage shelf with an anti-tipping structure, including a placement board 1. The lower surface of the placement board 1 is rotatably connected to a moving component. The moving component includes a first threaded rod 15. The upper end of the first threaded rod 15 is rotatably connected to the lower surface of the placement board 1. When the first threaded rod 15 rotates, the moving board 14 can move up and down on the outer surface of the first threaded rod 15. A first gear 13 is fixedly connected to the outer surface of the first threaded rod 15. When the first gear 13 rotates, it can drive the first threaded rod 15 to rotate. A bracket 25 is fixedly connected to the left surface of the placement board 1. Multiple groups of brackets 25 are provided to effectively fix the placement board 1. A fixing component is fixedly connected to the left surface of the bracket 25. The fixing component can enhance the overall stability of the shelf. The fixing component includes a fixing plate 3. The setting of the fixing plate 3 can fix the threaded rod 5 on the bracket 25. The right surface of the fixing plate 3 is fixedly connected to the left surface of the bracket 25. A groove 4 is opened on the lower surface of the fixing plate 3. An inclined plate 24 is fixedly connected to the upper surface of the placement board 1. The front surface of the inclined plate 24 is fixedly connected to the rear surface of the bracket 25. The setting of the inclined plate 24 is to make the stability between several placement boards 1 and brackets 25 stronger and not easily deformed. The lower surface of the bracket 25 is fixedly connected to the upper surface of a cylinder 23. A wheel 21 is fixedly connected to the lower surface of the cylinder 23. The setting of the wheel 21 can make the movement of the shelf more labor-saving and convenient.

[0031] Refer to Figure 2 , the fixing component further includes a threaded rod 5. The upper surface of the threaded rod 5 is rotatably connected to the inner wall of the groove 4. The threaded rod 5 rotates on the inner wall of the groove 4. A sliding rod 6 is threadedly connected to the outer surface of the threaded rod 5. When the threaded rod 5 rotates, the sliding rod 6 moves up and down on the outer surface of the threaded rod 5. An arc groove 8 is internally formed through the sliding rod 6. A disc 9 is fixedly connected to the lower surface of the threaded rod 5. A round rod 10 is fixedly connected to the lower surface of the disc 9. When it is necessary to change the state of the fixing block 2, rotate the round rod 10. The round rod 10 drives the disc 9 and the threaded rod 5 to rotate. A fixing block 2 is rotatably connected to the left surface of the placement board 1. A short rod 7 is fixedly connected to the left surface of the fixing block 2. The short rod 7 drives the fixing block 2 to rotate, thereby changing the position of the fixing block 2. An empty groove is formed through the front surface of the bracket 25. The fixing block 2 is rotatably connected to the inner wall of the empty groove. The outer surface of the short rod 7 slides on the inner wall of the arc groove 8. When the sliding rod 6 moves up and down, the short rod 7 slides in the arc groove 8.

[0032] Refer to Figure 3, the moving component further includes a second gear 12 and a cylinder 23. The outer surface of the second gear 12 meshes with the outer surface of the first gear 13. When the second gear 12 rotates, it can drive the first gear 13 to rotate. A rotating rod 11 is fixedly connected to the lower surface of the second gear 12. Pulling the rotating rod 11 to rotate drives the second gear 12 to rotate. A moving plate 14 is threadedly connected to the outer surface of the first threaded rod 15. A long rod 20 is fixedly connected to the left surface of the moving plate 14. A ring 22 is fixedly connected to the left end of the long rod 20. When the moving plate 14 moves up and down, it drives the long rod 20 to move up and down. The long rod 20 drives the ring 22 to slide up and down on the outer surface of the cylinder 23. The inner wall of the ring 22 slides on the outer surface of the cylinder 23. The second gear 12 is rotatably connected to the lower surface of the storage plate 1. A rectangular groove 16 is formed through the inside of the moving plate 14. There are multiple groups of the rectangular grooves 16. A rotating rod 17 is rotatably connected to the inner wall of the rectangular groove 16. A chevron-shaped block 18 is fixedly connected to the outer surface of the rotating rod 17. The chevron-shaped block 18 is made of rubber. When the chevron-shaped block 18 moves downward and contacts the ground and is compressed, the rotating rod 17 rotates. A scroll spring 19 is fixedly connected to the outer surface of the rotating rod 17. When moving the storage rack, move the chevron-shaped block 18 upward. The scroll spring 19 resets and drives the chevron-shaped block 18 to reset. The other end of the scroll spring 19 is fixedly connected to the inner wall of the rectangular groove 16.

[0033] Working principle: When in use, push the storage rack to the designated position. After moving the rack to the designated position, rotate the round rod 10 to drive the disc 9 and the threaded rod 5 to rotate. At this time, the sliding rod 6 and the threaded rod 5 are threadedly connected, so the sliding rod 6 moves downward. Since the short rod 7 slides inside the arc groove 8 and drives the fixed block 2 to rotate downward. When the fixed block 2 moves to the position where it contacts the ground, stop rotating the round rod 10.

[0034] When the entire storage rack is fixed, rotate the rotating rod 11 to drive the second gear 12 and the first gear 13 to rotate. Then the first threaded rod 15 fixed to the inner surface of the first gear 13 rotates. Since the first threaded rod 15 and the moving plate 14 are threadedly connected, when the first threaded rod 15 rotates, the moving plate 14 moves downward. The long rod 20 fixed to the moving plate 14 drives the ring 22 to slide downward on the outer surface of the cylinder 23. At the same time, the rotating rod 17 rotatably connected to the inner wall of the rectangular groove 16 drives the chevron-shaped block 18 to move downward. When the chevron-shaped block 18 contacts the ground and continues to move downward, the scroll spring 19 is compressed until it moves to the appropriate position, then stop rotating the rotating rod 11.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used 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 recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
