[0001] This utility model relates to the field of refrigerator shelf technology, specifically a foldable refrigerator shelf. Background Technology

[0002] Refrigerator shelves are structural components inside a refrigerator used to separate and hold food and other items. They are usually made of materials such as metal, plastic, or glass and are fixed to both sides of the refrigerator liner by means of slots, slides, or shelf supports to form multiple storage spaces.

[0003] In related technologies, the current shelf design has certain limitations. Its structure cannot achieve flipping or folding functions, which brings many inconveniences in actual use. Especially when it is necessary to store items that are taller than the usual size, the shelf cannot be flexibly adjusted, making it difficult to store these extra-tall items. This structural defect not only affects the space utilization of the shelf, but also greatly limits its functionality. As a result, users often encounter problems such as insufficient storage space or difficulty in placing items, making it inconvenient for users.

[0004] Therefore, it is necessary to provide a foldable refrigerator shelf to solve the above-mentioned technical problems. Utility Model Content

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.

[0017] Please see Figure 1-4 A foldable refrigerator shelf includes a first refrigerator shelf 1, a second refrigerator shelf 2 is provided on the right side of the first refrigerator shelf 1, a fixing block 3 is fixedly connected to the right side of the first refrigerator shelf 1, a metal rod 4 is rotatably connected to the inner side of the fixing block 3, a metal frame 5 is rotatably connected to the surface of the metal rod 4, the metal frame 5 is fixedly connected to the left side of the second refrigerator shelf 2, and a fixing component 6 is provided on the right side of the first refrigerator shelf 1. The fixing component 6 is used to fix the metal rod 4.

[0018] Please see Figure 4 The fixing component 6 includes a gear 61, which is fixedly connected to the surface of the metal rod 4. A pad 62 is fixedly connected to the right side of the first refrigerator shelf 1. A limit frame 63 is fixedly connected to the top of the pad 62. A toothed plate 64 is provided at the bottom of the limit frame 63. The toothed plate 64 meshes with the gear 61. A slide rod 65 is fixedly connected to the top of the toothed plate 64. The slide rod 65 is slidably connected to the limit frame 63.

[0019] Furthermore, the device, through the fixing component 6 system, enables flexible flipping of the second refrigerator shelf 2. This design not only makes the placement of items more convenient and diverse, but also significantly improves the safety performance during use and greatly enhances the user's operating experience.

[0020] Please see Figure 4 A connecting plate 7 is fixedly connected to the inner side of the toothed plate 64, and a positioning rod 8 is fixedly connected to the top of the connecting plate 7. The positioning rod 8 is slidably connected to the limiting frame 63. A spring 9 is fixedly connected to the top of the connecting plate 7, and the top of the spring 9 is fixedly connected to the top of the inner wall of the limiting frame 63.

[0021] Furthermore, the spring 9 mechanism inside the device can apply a continuous clamping force to the connecting plate 7. This elastic support structure effectively ensures the stability of the connecting plate 7 in the working state and completely avoids the possible shaking of the connecting plate 7, thus providing users with a more reliable and stable user experience.

[0022] Please see Figure 1 A limit handle 10 is fixedly connected to the top of the connecting plate 7, and the top of the limit handle 10 extends through to the top of the limit frame 63.

[0023] Furthermore, in terms of ease of operation, the device is equipped with a user-friendly limit handle 10 design. Users can easily adjust the height of the connecting plate 7 by simply pulling it from the top. This design is not only intuitive and easy to operate, but also extremely stable during operation, fully demonstrating the excellent stability of the device and allowing users to enjoy a smoother operating experience.

[0024] Please see Figure 4 There are several positioning rods 8, which are evenly distributed in a straight line.

[0025] Furthermore, to further enhance the stability of the device, the designers adopted a configuration scheme with multiple positioning rods 8. The synergistic effect between the multiple positioning rods 8 and the limiting frame 63 forms a reliable limiting mechanism. This multi-fixing method fundamentally eliminates the problem of shaking of the connecting plate 7, ensuring the absolute stability of the entire device during operation and providing users with more reassuring usage assurance.

[0026] Please see Figure 4 The number of limit frames 63 and fixing blocks 3 is set to several, and the limit frames 63 and fixing blocks 3 are evenly distributed in a straight line.

[0027] Furthermore, in terms of mobility, the device adopts multiple limiting frames 63 and multiple fixing blocks 3. This configuration not only makes the movement of the second refrigerator shelf 2 component more flexible and free, but also significantly enhances the stability of the overall structure through multi-point fixing, allowing users to obtain a stable and reliable operating experience in various usage scenarios.

[0028] Please see Figure 4 The number of slide bars 65 is set to two, and the slide bars 65 are located on the left side of the second refrigerator shelf 2.

[0029] Furthermore, the device employs a dual slide bar 65 design to achieve efficient positioning with the connecting frame. This dual-rail guiding system not only has extremely high positioning efficiency but also perfectly maintains the operational stability of the toothed plate 64, ensuring that the device maintains optimal performance under various working conditions and providing users with a long-lasting and stable user experience.

[0030] The specific implementation process of this utility model is as follows: When it is necessary to flip and fold the structure of the second refrigerator shelf 2, the user only needs to hold the operating handle and apply an upward force. At this time, the operating handle will drive the connecting plate 7 connected to it to move upward in the vertical direction through the mechanical linkage device. During the upward movement of the connecting plate 7, it will simultaneously drive the moving plate fixed on it to move upward together. The movement of the moving plate will further cause the toothed plate 64 meshing with it to also move upward. When the toothed plate 64 rises to a certain height, it will completely disengage from the gear 61 below. At this time, the unconstrained gear 61 begins to rotate freely under the action of gravity or other external forces. The rotational motion of the gear 61 is transmitted to the metal rod 4 through the transmission mechanism, causing the metal rod 4 to generate a corresponding rotation. The rotational motion, through this series of mechanical transmissions, ultimately enables the second refrigerator shelf 2 to flip, allowing it to rotate to a preset angle position. This design is particularly suitable for situations where items that are too tall to the bottom need to be placed, providing ample operating space. After flipping, the user simply releases the operating handle, and the built-in spring 9 immediately takes effect, applying downward elastic pressure to the connecting plate 7. This pressure is transmitted through the connecting plate 7 to the toothed plate 64, causing the toothed plate 64 to re-engage tightly with the gear 61. This engagement effectively locks the rotation of the gear 61, ensuring that the metal rod 4 remains stable. The entire mechanism is ingeniously designed, ensuring both ease of operation and structural stability after folding, ultimately achieving a highly efficient and reliable folding effect.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
