[0015] 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.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this utility model is a foldable storage structure for fruit and vegetable racks, comprising: The outer folding frame 11 and the inner folding frame 12 are provided. The inner middle of the outer folding frame 11 has a cavity, and movable springs are fixedly connected at equal intervals to the ends inside the cavity. One end of multiple movable springs is fixed to the inner end of the inner folding frame 12. The outer folding frame 11 is provided with a support column 14. The upper and lower outer surfaces of the support column 14 are fitted with collars 16. A first isolation plate 17 is fixed to one side of the outer surface of the upper collar 16, and a second isolation plate 18 is fixed to one side of the outer surface of the lower collar 16. The two sides above the inner folding frame 12 are provided with mounting brackets 111, and the ends of the mounting brackets 111 abut against the outer folding frame 11 and the inner folding frame 12 respectively. The movable spring connects and installs the outer folding frame 11 and the inner folding frame 12. With the help of the elastic force of the movable spring, the inner folding frame 12 can be unfolded and folded. The support column 14 is installed with the first partition plate 17 and the second partition plate 18 by means of the collar 16, which can divide the internal space of the storage rack to meet the needs of various fruits and vegetables. The additional rack 111 decorates and limits the unfolded inner folding frame 12.

[0018] A bearing seat 13 is fixed at the middle of the bottom of the inner side of the outer folding frame 11, and the middle of the bearing seat 13 fits into the bottom of the support column 14. The bearing seat 13 is installed on the support column 14 and allows for multi-angle adjustment.

[0019] Limiting rings 15 are fitted on the top and middle of the outer surface of the support column 14, and the distance between adjacent limiting rings 15 and between the support column 14 and the bearing seat 13 is greater than the outer diameter of the collar 16. The limiting ring 15 structurally limits the collar 16 and satisfies its movement requirements.

[0020] The bottom end of the first isolation plate 17 is fitted with a first mounting plate 19, and the top end of the second isolation plate 18 is fitted with a second mounting plate 110. The first isolation plate 17 and the second isolation plate 18 are both provided with limiting grooves at the center of their front sides, and the inner walls of the limiting grooves abut against the outer edges of the first isolation plate 17 and the second isolation plate 18. The first mounting plate 19 and the second mounting plate 110 are used in conjunction with the first isolation plate 17 and the second isolation plate 18 to complete the division of the internal space of the storage rack. With the help of the limiting groove, the first mounting plate 19 and the second mounting plate 110 can be stored and limited after use, and the first isolation plate 17 and the second isolation plate 18 can be limited after being rotated to the same horizontal plane.

[0021] Working principle: When the storage rack is unfolded for use, an external pulling force is applied to the inner folding frame 12, which deforms with the help of the movable spring, causing the inner folding frame 12 to move out of the cavity. Then, the mounting bracket 111 is fitted onto the inner folding frame 12 to restrict the unfolded inner folding frame 12. At this time, the first mounting plate 19 and the second mounting plate 110 can be fitted onto the lower and upper parts of the first isolation plate 17 and the second isolation plate 18 respectively, and the first isolation plate 17 and the second isolation plate 18 are unfolded in a staggered manner. When folding it after use, the reverse operation steps are applied.

[0022] This solution satisfies both storage placement and post-use organization without taking up space. Furthermore, the addition of a movable first partition 17 and a second partition 18 inside the storage rack allows for the division of the internal space, further enhancing the usability. Moreover, the first partition 17 and the second partition 18 can still be folded during rotation, further reducing the space occupied during storage and meeting the requirements.

[0023] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment: It also includes an auxiliary storage module, which includes a movable frame 21 symmetrically fixed on the front and rear sides of the inner folding frame 12. A torsion spring 22 is connected through the middle of the movable frame 21. A connecting post 23 is fixedly connected between the relative torsion springs 22. A hole post 24 is fixed on one side of the outer surface of the connecting post 23, and a rubber head 26 is sleeved on one end of the hole post 24. An extension post 25 is fitted inside the opening at one end of the post 24, and one end of the extension post 25 is fitted into the rubber head 26. The movable frame 21 uses torsion spring 22 to install and fix the connecting column 23, and allows for angle adjustment. The connecting column 23 is used to fix the hole column 24. In addition, the extension column 25 is used to protect the retracted inner folding frame 12 from impact by the rubber head 26 and the contact between the extension column 25 and the outer folding frame 11.

[0024] Working principle: When the inner folding frame 12 is folded up, the movable spring after the force is released returns to its original deformation and actively pulls the inner folding frame 12 into the cavity. During this process, an extension post 25 is added to one end of the post 24 in advance, and a rubber head 26 is fitted onto one end of the extension post 25. Subsequently, the contact between the rubber head 26 and the inner folding frame 12 can limit the pull-back inner folding frame 12.

[0025] This solution can provide impact protection for the actively folding inner frame 12 during storage, reducing the degree of damage and saving costs.
