[0032] The present invention provides a shelf 100 for being fixed to the inner liner of a storage device. Figures 1 to 9 An embodiment according to the present invention is shown.

[0033] As Figures 1 to 3 shown, the shelf 100 includes a shelf board 1 and side brackets 2. The shelf board 1 includes a bearing board 11, positioning columns 12 arranged on both sides of the bearing board 11, and a support structure 13. The bearing board 11 has a first surface 111 and a second surface 112 arranged back to back. The positioning columns 12 and the support structure 13 are arranged at intervals before and after on the front side of the bearing board 11.

[0034] The side brackets 2 are arranged on both sides of the shelf board 1. The width of the bearing board 11 is less than the distance between the two side brackets 2, so that an installation space for the shelf board 1 is formed between the two side brackets 2. The positioning columns 12 and the support structure 13 on the side surface of the bearing board 11 correspond to the side brackets 2 on both sides.

[0035] The side brackets 2 are provided with a support platform 21 that cooperates with the support structure 13 and a guide groove 22 that cooperates with the positioning column 12. The positioning column 12 is slidably connected in the guide groove 22. Through the mutual cooperation of the positioning column 12 and the guide groove 22, accurate positioning of the shelf board 1 on the side brackets 2 is achieved, and the cooperation between the support structure 13 and the support platform 21 can further provide additional supporting force.

[0036] Wherein, when the positioning column 12 slides along the guide groove 22 to the first position, the support structure 13 is located on the support platform 21, and the positioning column 12 is engaged with the guide groove 22 to fix the shelf board 1 to the side brackets 2.

[0037] When the positioning column 12 slides along the guide groove 22 to the second position, the support structure 13 can be disengaged from the support platform 21, so that the shelf board 1 can rotate around the positioning column 12 to switch the use of the first surface 111 or the second surface 112 of the shelf board 1.

[0038] The shelf 1 is slidably engaged with the side bracket 2 through the positioning posts 12 sliding along the guide grooves 22, enabling the user to adjust the usage state of the shelf 1 according to actual needs. When it is necessary to stably carry items, the positioning posts 12 are slid together with the shelf 1 to the first position, where they can be engaged with the guide grooves 22 on the side bracket 2, fixing the shelf 1 to the side bracket 2.

[0039] When it is necessary to switch between using the first surface 111 or the second surface 112 of the shelf 1, the user only needs to simply slide the positioning posts 12 together with the shelf 1 to the second position, and then the shelf 1 can be rotated to switch the currently used surface to the other side. The operation is convenient, time-saving and labor-saving. By switching the usage surface of the shelf 1, the problems of single panel material, insufficient performance and inconvenient replacement in the prior art can be quickly solved. There is no need to disassemble or replace the entire shelf 100, enabling the shelf 100 to adapt to the storage needs of different food ingredients, meet the diverse storage needs of users, and improve the flexibility and practicality of the shelf 100.

[0040] Specifically, as Figure 4 shown, the bearing plate 11 includes a first plate member 14 and a second plate member 15 that are stacked on top of each other, and a frame assembly 16 that covers the four peripheral edges of the first plate member 14 and the second plate member 15. The first plate member 14 has a first surface 111 exposed on the outside, and the second plate member 15 has a second surface 112 exposed on the outside.

[0041] Of course, in some other embodiments, the bearing plate 11 may be composed of only a single plate member, and the first surface 111 and the second surface 112 are the upper and lower surfaces of the single plate member.

[0042] The first surface 111 or the second surface 112 can be set according to actual needs. For example, when it is necessary to store heavier items, a load-bearing plate with a more solid structure can be selected to set the first surface 111; when storing items that are prone to moisture, the second surface 112 with moisture-proof performance can be selected; or when storing containers or items that are prone to slipping or breaking, the second surface 112 with an anti-slip layer can be selected to prevent the items from slipping.

[0043] In this embodiment, the first plate member 14 is a load-bearing plate, and the load-bearing plate is not limited to materials such as glass and aluminum alloy; the second plate member 15 is an anti-slip plate, and an anti-slip layer is provided on its second surface 112. The material of the anti-slip layer is silicone or other elastic polymers, which has a buffering and anti-slip effect.

[0044] The side bracket 2 can be pre-fixed to the inner liner of the storage device through fasteners. Through the positioning posts 12 and the support structure 13 of the shelf 1, they protrude from the left and right sides of the bearing plate 11 to cooperate and connect with the side brackets 2 on both sides.

[0045] Specifically, the support structure 13 cooperates with the support platform 21, and the positioning post 12 cooperates with the guiding groove 22 to position and slidably mount the storage board 1 onto the side bracket 2, that is, the installation of the storage board 1 on the inner liner of the storage device is realized.

[0046] As Figure 3 , the guiding groove 22 extends along the depth direction. When the storage board 1 is installed onto the side bracket 2, the positioning post 12 is cooperatively limited within the guiding groove 22. It should be noted that the depth direction is the front-back direction of the shelf 100.

[0047] The cooperative setting of the positioning post 12 and the guiding groove 22 enables the positioning post 12 to stably slide along the guiding groove 22 within the guiding groove 22 when the storage board 1 adjusts its position, ensuring the smoothness of the storage board 1 during movement. On the other hand, when the storage board 1 rotates, the guiding groove 22 can also cooperate to support the positioning post 12 to prevent the storage board 1 from falling off the side bracket 2.

[0048] The positioning post 12 realizes the switching between the first position and the second position by sliding to the opposite first end 221 and second end 222 of the guiding groove 22. The guiding groove 22 provides a clear movement path for the storage board 1, enabling the user to easily adjust the storage board 1 to the desired first position or second position.

[0049] In this embodiment, as Figure 6 and 7 shown, when the positioning post 12 slides to the rear end of the guiding groove 22, the storage board 1 is in the first position. As Figure 8 and Figure 9 shown, when the positioning post 12 slides to the front end of the guiding groove 22, the storage board 1 is in the second position.

[0050] The first end 221 of the guiding groove 22 is provided with a clamping portion 223. When the storage board 1 slides to the first position, the clamping portion 223 is clamped and fixed with the positioning post 12 to limit the movement of the positioning post 12 along the depth direction and fix the storage board 1 thereto.

[0051] In this embodiment, the clamping portion 223 extends downward from the rear end portion of the guiding groove 22 to form a groove structure matching the shape of the positioning post 12. When the positioning post 12 slides to the rear end of the guiding groove 22 and reaches the first position, the positioning post 12 is driven by gravity to sink downward into the clamping portion 223. The clamping portion 223 can limit the movement of the positioning post 12 along the depth direction, thereby fixing the storage board 1 in the first position and preventing the storage board 1 from moving by itself without operation.

[0052] When it is necessary to move the storage board 1 to the second position, the user applies a certain external force to enable the positioning post 12 to overcome the clamping force of the clamping part 223 and slide forward along the guide groove 22.

[0053] When the storage board 1 slides to the second position, the storage board 1 can rotate around the positioning post 12 to switch the first surface 111 or the second surface 112 upward, replacing the use surface for placing items.

[0054] The support platform 21 extends linearly along the depth direction of the side bracket 2, providing stable sliding guidance for the support structure 13. The support structure 13 moves on the support platform 21, facilitating the easy conversion of the storage board 1 between the first position and the second position, making the operation more labor-saving and convenient.

[0055] Refer to Figures 3 to 5 As shown, a groove 211 for fitting and accommodating the support structure 13 is further provided on the support platform 21. The groove 211 is used to limit the movement of the support structure 13 along the depth direction when the positioning post 12 slides to the first position.

[0056] When the storage board 1 is in the first position, the positioning post 12 sinks downward into the clamping part 223, and the roller just fits downward into the groove 211, forming an effective double limit to prevent the storage board 1 from sliding by itself without operation, enhancing the stability and safety of the storage rack 100.

[0057] The support structure 13 includes a first roller 131 and a second roller 132 spaced on the front and rear sides of the positioning post 12. First grooves 2111 and second grooves 2112 for fitting and accommodating the first roller 131 and the second roller 132 are provided on the support platform 21.

[0058] In this embodiment, the positioning post 12 is arranged at the middle position on both side surfaces of the storage board 1, and the first roller 131 and the second roller 132 are respectively arranged on the front and rear sides thereof, so that the storage board 1 can maintain balance during sliding, avoiding shaking or jamming caused by uneven force.

[0059] Correspondingly, first grooves 2111 and second grooves 2112 for fitting and accommodating the first roller 131 and the second roller 132 are provided in the support platform 21. When the storage board 1 is in the first position, the first roller 131 and the second roller 132 simultaneously fit downward into the first grooves 2111 and the second grooves 2112.

[0060] The side bracket 2 is provided with an avoidance groove 23 that separates the support platform 21. When the positioning post 12 slides along the guiding groove 22 to the second position, the support structure 13 disengages from the support platform 21, and the support structure 13 is located within the avoidance groove 23 or outside the side bracket 2. The avoidance groove 23 corresponds to the rotation trajectory of the support structure 13 when the storage board 1 rotates.

[0061] When it is necessary to rotate and switch the use surface, the storage board 1 slides to the second position, and the support structure 13 rotates together with the storage board 1. The avoidance groove 23 provides sufficient space for the rotation of the support structure 13, avoiding collisions and frictions between the support structure 13 and the side bracket 2, and ensuring the smoothness and stability of the rotation of the storage board 1.

[0062] As Figure 8 shown, when the positioning post 12 slides along the guiding groove 22 to the second position, one of the first roller 131 and the second roller 132 is located within the avoidance groove 23, and the other is located outside the side bracket 2, ensuring that during the rotation of the storage board 1, the support structure 13 can smoothly disengage from the support platform 21 and move along the avoidance groove 23 or outside the side bracket 2 without interfering with other parts of the side bracket 2, making the operation more smooth and stable when the storage board 1 switches between the two use surfaces and improving the user experience.

[0063] Meanwhile, the shape and size of the avoidance groove 23 correspond to the rotation trajectory of the support structure 13 when the storage board 1 rotates, so as to ensure that the support structure 13 can accurately move along a predetermined path during the rotation process.

[0064] The guiding groove 22 extends from the inner side of the support platform 21 in a direction away from the bearing plate 11. The support structure 13 and the positioning post 12 are arranged on the same horizontal line of the storage board 1, so that when the storage board 1 is slidably installed, both the positioning post 12 and the support structure 13 are supported and guided by the support platform 21, so that the storage board 1 always moves in a straight line during the sliding process, avoiding the occurrence of deviation or skew phenomena, and further improving the stability and smoothness of the sliding of the storage board 1.

[0065] The positioning post 12 slides on the support platform 21 along with the storage board 1 and is inserted into the guiding groove 22 from the side of the side bracket 2 close to the storage board 1.

[0066] In addition, the positioning post 12 has elasticity. When it slides along the side bracket 2, it is compressed and contracted, and resets and is inserted into the guiding groove 22 when it slides into the guiding groove 22.

[0067] When installing the shelf 1 on the side bracket 2, the support structure 13 of the shelf 1 slides along the support platform 21 of the side bracket 2, and the support platform 21 presses against the positioning post 12 protruding outside the frame assembly 16, causing it to contract inward. When the positioning post 12 slides to the guiding groove 22, it will automatically reset under the action of the elastic restoring force and snap into the guiding groove 22. The peripheral wall of the guiding groove 22 will limit the positioning post 12 to prevent the positioning post 12 from detaching from the guiding groove 22 and avoid the shelf 1 from falling off the side bracket 2.

[0068] The length by which the positioning post 12 protrudes outward from the frame assembly 16 is greater than that of the support structure 13, ensuring that the positioning post 12 can extend into the guiding groove 22 and play a key positioning and fixing role during the sliding installation process.

[0069] The following will describe the installation and adjustment process of the shelf 100 provided by the embodiments of the present invention:

[0070] When installing the shelf 100, the side bracket 2 has been pre-fixed to the inner liner of the storage device by fasteners. Assuming that the user needs to use the first surface 111, first, the first surface 111 of the shelf 1 needs to be placed upward and accurately aligned with the position of the side bracket 2. Align the first roller 131 at the upper rear end of the shelf 1 with the entrance of the support platform 21, and gently push the shelf 1 to make the first roller 131 smoothly enter the support platform 21. When the shelf 1 slides along the support platform 21, the first roller 131 first contacts the support platform 21, providing preliminary sliding support and guidance.

[0071] Subsequently, the positioning post 12 slides following the first roller 131 and gradually approaches the guiding groove 22. Since the positioning post 12 is elastic, it is in a contracted state within the support platform 21, and its fully expanded length is greater than the length by which the roller protrudes, enabling the positioning post 12 to smoothly snap into the guiding groove 22 after the first roller 131 and ensuring that the shelf 1 can be accurately installed in place.

[0072] As Figure 6 and Figure 7 shown, when the positioning post 12 continues to slide to the first end 221, i.e., the preset first position, the first roller 131 and the second roller 132 will simultaneously and exactly fit into the first groove 2111 and the second groove 2112 within the support platform 21. At this time, the positioning post 12 cooperates with the downwardly recessed clamping portion 223 to jointly form an effective limit, fixing the shelf 1 to the side bracket 2 and preventing the shelf 1 from sliding on its own without operation.

[0073] When the user needs to switch to use the second surface 112 of the storage board 1 according to actual needs, only a certain external force needs to be applied to pull the storage board 1 forward, so that the positioning post 12 overcomes the clamping force of the clamping portion 223 and slides forward along the guiding groove 22 to the second end 222 at the front side. The first roller 131 and the second roller 132 move forward along the support table 21, and the whole storage board 1 comes to the preset second position. As Figure 8 and Figure 9 shown, at this time, the second roller 132 originally located inside the support table 21 will move to the outside of the side bracket 2, while the first roller 131 moves into the avoidance groove 23 to ensure that there is no collision and interference between the first roller 131 and the side bracket 2 when the storage board 1 is flipped.

[0074] Operate the storage board 1 to rotate 180 degrees clockwise around the axis of the positioning post 12, so that the second surface 112 faces upward. Due to the flipping of the storage board 1, the positions of the first roller 131 and the second roller 132 are swapped with each other.

[0075] After the storage board 1 rotates in place, then push the storage board 1 to slide backward and return to the first position, that is, the preset fixed position.

[0076] In this process, the second roller 132 will slide into the first groove 2111 where the first roller 131 was originally located, while the first roller 131 is embedded in the second groove 2112. The positioning post 12 cooperates with the clamping portion 223 again to ensure that the storage board 1 is firmly fixed on the side bracket 2. At this time, the second surface 112 of the storage board 1 is completely facing upward, and the user can place or take items on the second surface 112 of the storage board 1 according to needs. The whole operation process is simple and smooth, effectively improving the utilization efficiency and flexibility of the storage space.

[0077] Another aspect of the present invention further provides a storage device, including an inner container that defines a storage space therein, and further including the storage rack 100 described in any one of the above, and the storage rack 100 is installed on the inner container.

[0078] In summary, in the present invention, by sliding the positioning post of the storage board along the guiding groove to the first position, the positioning post can be engaged with the guiding groove to fix the storage board on the side bracket; by sliding the positioning post along the guiding groove to the second position, the rotation of the storage board can be operated to switch the use surface. The present invention realizes the flexible conversion of the storage board in a limited space by setting the flipping of the storage board, greatly improving the utilization rate and convenience of the storage space.
