Description

Technical Field

[0001] This utility model specifically relates to a refrigerator shelf support frame. Background Technology

[0002] Traditional refrigerator shelves typically use a fixed support structure, requiring manual disassembly or reinstallation of the support components for height adjustment. This process is cumbersome and prone to component loss. Existing adjustable shelves mostly use sliding rails or snap-on structures, which have the following drawbacks: poor adjustment flexibility: the shelf must be completely removed to adjust the height, affecting the continuity of items stored inside the refrigerator; insufficient structural stability: sliding rail designs are prone to shifting under load, and snap-on structures are prone to loosening after long-term use; low space utilization: the support components cannot be folded, still occupying vertical space when not in use, affecting the storage of large items. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a refrigerator shelf support frame.

[0004] A refrigerator shelf support frame includes a frame body that can be locked inside the refrigerator. The frame body has two members arranged opposite to each other. The frame body includes two vertical support rods and a plurality of horizontal support rods vertically spaced between the two vertical support rods. A plurality of pivots are vertically spaced between the two vertical support rods, each pivot corresponding to one of the horizontal support rods. Support members are rotatably mounted on each pivot. These support members can be rotatably positioned to abut against the lower side of the horizontal support rods to keep them horizontal, and can also rotatably abut against the inner side of the horizontal support rods to keep them vertical.

[0005] In one embodiment, a guide post is provided on one side of the support vertical rod, and a shelf is movably sleeved on the guide post. The shelf can movably abut against the horizontal support member, and the shelf does not contact the vertical support member when it is moving.

[0006] In one embodiment, the cross-section of the guide post is arranged in an arc shape, and the two sides of the shelf are recessed with limiting grooves that can fit and cooperate with the guide post.

[0007] In one embodiment, a connecting assembly is provided between the shelf and the support member.

[0008] In one embodiment, the connecting component includes an L-shaped connector and a limiting member; wherein, the support member has a notch in the middle, one end of the L-shaped connector is rotatably disposed in the notch, the limiting member is movably disposed on the shelf and can move closer to or further away from the shelf body, a slot is provided on one side of the limiting member, and one end of the L-shaped connector can be engaged in the slot.

[0009] In one embodiment, the inner side of the slot has a rubber pad to increase the friction between the slot and the L-shaped connector.

[0010] In one embodiment, the shelf has a plurality of connecting rods spaced apart along the same horizontal axis, and the limiting member is movably sleeved on the connecting rods.

[0011] In summary, the advantages of this utility model over the prior art are:

[0012] This utility model's support component is hinged to a supporting vertical rod via a pivot, allowing it to switch between horizontal (load-bearing) and vertical (folded) states around the pivot. In the horizontal state, the upper surface of the support component abuts against the lower side of the supporting horizontal rod, forming a stable force-bearing surface. The supporting horizontal rod acts as a limiting structure, rigidly restricting the rotation angle of the support component through contact, ensuring even load-bearing in the horizontal state and preventing tipping. In the vertical state, the support component retracts inward and rests against the inner side of the supporting horizontal rod, reducing space occupation. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 5The present invention preferably provides a refrigerator shelf support frame, comprising a frame 1 that can be locked inside the refrigerator. Two frame 1s are arranged opposite each other. Each frame 1 includes two vertical support rods 2 and a plurality of horizontal support rods 3 vertically spaced between the two vertical support rods 2. A plurality of pivots 4 are vertically spaced between the two vertical support rods 2, each pivot 4 corresponding to one of the horizontal support rods 3. Support members 5 are rotatably mounted on each pivot 4. The support members 5 can rotate and be limited to abutting against the lower side of the horizontal support rods 3 to keep the support members 5 in a horizontal state, and can also rotate and abut against the inner side of the horizontal support rods 3 to keep the support members 5 in a vertical state. Specifically, the support members are hinged to the vertical support rods via pivots, and can switch between horizontal (load-bearing) and vertical (storage) states around the pivots. In the horizontal position, the upper surface of the support member abuts against the lower side of the support crossbar, forming a stable force-bearing surface. The support crossbar acts as a limiting structure, restricting the rotation angle of the support member through rigid contact, ensuring uniform load-bearing in the horizontal position and preventing overturning. In the vertical position, the support member is recessed and close to the inner side of the support crossbar, reducing space occupation.

[0020] Furthermore, a guide post 6 is provided on one side of the supporting vertical rod 2, and a shelf 7 is movably sleeved on the guide post 6. The shelf 7 can movably abut against the horizontally positioned support member 5, and the shelf 7 does not contact the vertically positioned support member 5 when it moves. Specifically, the guide post enables the vertical displacement of the shelf, and since the shelf does not contact the vertically positioned support member when it moves, height adjustment can be achieved without disassembling the shelf. Moreover, due to the stability of the vertical displacement of the shelf during adjustment, the risk of items placed on the shelf falling is effectively avoided.

[0021] Furthermore, the guide post 6 has a cross-section with an arc shape, and the shelf 7 has recessed limiting grooves 8 on both sides that can fit into the guide post 6. The arc-shaped cross-section of the guide post and the limiting groove allows the shelf to both guide and prevent slippage when sliding along the guide post. The arc design increases the contact area and distributes the load.

[0022] Furthermore, a connecting assembly is provided between the shelf 7 and the support member 5. Further, the connecting assembly includes an L-shaped connector 9 and a limiting member 10; wherein, a notch 11 is provided in the middle of the support member 5, one end of the L-shaped connector 9 is rotatably disposed within the notch 11, the limiting member 10 is movably disposed on the shelf 7 and can move closer to or further away from the frame 1, a slot 12 is provided on one side of the limiting member 10, and one end of the L-shaped connector 9 can be engaged in the slot 12.

[0023] When the support is horizontal, the L-shaped connector engages with the slot of the limiting piece, thus achieving a fixed connection between the shelf and the support. When the height needs to be adjusted, the limiting piece is pulled to disengage the L-shaped connector, allowing the shelf to slide freely, and the support automatically switches to a vertical position to avoid interference.

[0024] Furthermore, the inner side of the card slot 12 has a rubber pad to increase the friction between the card slot 12 and the L-shaped connector 9. This friction from the rubber pad keeps the card slot connected to the L-shaped connector, thereby fixing the shelf position.

[0025] Furthermore, the shelf 7 has several connecting rods 13 arranged at intervals along the same horizontal axis, and the limiting member 10 is movably sleeved on the connecting rod 13. The limiting member sleeved on the connecting rod can move laterally to adapt to different shelf widths and improve versatility.

[0026] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
