Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a foldable shelf and refrigerator storage cabinet. Background Technology
[0002] In the current refrigerator and freezer market, internal partitions are mostly made of EPS (expanded polystyrene) or folding corrugated cardboard. However, both solutions have significant drawbacks. First, while EPS material possesses certain strength and insulation properties, it requires individual molding for different structural needs, increasing production costs. Furthermore, it is prone to particle shedding during use, which not only affects user experience but also pollutes the environment. In addition, with increasing global environmental awareness and the implementation of plastic restriction orders in overseas markets, some countries have begun to restrict the use of EPS and other foamed packaging products.
[0003] On the other hand, while folding corrugated boxes are less expensive, they require manual folding, which is inefficient. Furthermore, due to strength issues, multiple layers are often needed to meet usage requirements, further reducing assembly efficiency. In addition, the need to match partitions of different structural dimensions results in inconsistent partition thicknesses, occupying significant transport space and hindering logistics and warehousing management.
[0004] In order to solve the above-mentioned technical problems, this utility model designs a foldable shelf and a refrigerator storage cabinet. Utility Model Content
[0005] This utility model provides a foldable partition, which aims to solve the problems of existing partition EPS materials requiring separate molding, easy particle pollution, and the large transportation space occupied by foldable corrugated cardboard boxes and low efficiency due to manual folding.
[0006] A foldable partition includes: a partition base plate having a pre-grooved structure, the pre-grooved structure enabling the partition base plate to be bent along the groove line when subjected to force; elastic band hooks are symmetrically arranged on the partition base plate, and elastic band slots and partition slots are formed.
[0007] Limiting elastic band; the limiting elastic band is hung on both sides on the elastic band hook, and the middle part passes through the elastic band slot and is arranged crosswise.
[0008] Based on the above technical solution, two parallel grooves are provided on the partition base plate, and the limiting elastic band is in a stretched state when the partition base plate is unfolded, providing an inward folding force to both ends of the partition base plate through elastic tension.
[0009] Furthermore, a limiting block is glued onto the spacer substrate.
[0010] Preferably, the partition base plate is a wooden board or a corrugated board.
[0011] A refrigerator storage cabinet, characterized in that it includes a cabinet body, a shelf, and the aforementioned shelf, wherein the shelf and the shelf are disposed within the cabinet body.
[0012] Furthermore, a placement slot is provided on the cabinet, and the shelf is slidably connected in the placement slot and the shelf is slidably connected in the partition slot.
[0013] Beneficial effects
[0014] Compared with existing technologies, the advantages of this invention are as follows: the shelf base plate adopts a pre-grooved structure design, which allows it to bend and form along the groove line when under stress. This design allows the shelf to be folded up when not in use, greatly reducing the space required for storage and transportation. The shelf base plate is symmetrically equipped with elastic band hooks, elastic band slots, and partition slots. These designs simplify the assembly and disassembly process, eliminating the need for complex tools or steps and improving operational convenience. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0025] like Figure 1 and Figure 2 As shown, a foldable partition includes: a partition base plate 1 and a limiting elastic band 4.
[0026] The partition base plate 1 is the main supporting part of the entire partition, and is made of wood or corrugated board, providing sufficient strength and stability.
[0027] like Figure 3 and Figure 4 As shown, the partition substrate 1 has a pre-grooved structure, which allows the partition substrate 1 to be bent and shaped along the groove line when subjected to force. The pre-grooved structure on the partition substrate allows it to be bent and shaped along a specific groove line when subjected to force, so that the partition can be adjusted in shape as needed to adapt to different storage requirements.
[0028] Rubber band hooks 3 are symmetrically arranged on the partition base plate 1 to fix the two ends of the limiting rubber band 4, ensuring that the rubber band can be securely hung on the partition base plate.
[0029] The partition base plate 1 has rubber band slots 2 and partition slots 7. The rubber band slots 2 are used to guide and limit the position of the limiting rubber bands 4 to ensure that they maintain the correct direction and position during use.
[0030] The limiting elastic bands 4 are hung on the elastic band hooks 3 on both sides, and pass through the elastic band slot 2 in the middle and are arranged crosswise, so that they are in a stretched state when the partition is unfolded. The elastic tension provides an inward folding force to both ends of the partition base plate, which facilitates quick folding.
[0031] Two parallel grooves are provided on the partition base plate 1. These grooves work in conjunction with the limiting elastic band 4. When the partition is unfolded, the limiting elastic band 4 is in a stretched state, providing the necessary tension so that the partition base plate 1 can stably maintain its shape. When folding is required, the elastic tension of the limiting elastic band helps to easily achieve inward folding, simplifying the operation process.
[0032] The partition base plate 1 is bonded with a limiting block 6, which is made of EVA. EVA (ethylene-vinyl acetate copolymer) is widely used in various protective and cushioning applications due to its excellent flexibility, elasticity, and chemical resistance. As a limiting block 6, EVA material is mainly used to protect the inner liner of refrigerators or freezers from scratches or other forms of physical damage.
[0033] The shelf base plate 1 is made of wood or corrugated board. Both wood and corrugated board have good mechanical strength, providing sufficient support, and are more environmentally friendly than traditional materials such as EPS (expanded polystyrene). Furthermore, the EVA limiting block 6 also has good environmental properties, meeting the current market trend of demand for green and sustainable products. To ensure the shelf base plate 1 can be used in the freezer, a waterproof coating or varnish should be applied to its surface to form a protective film and prevent moisture penetration. Commonly used waterproof coatings include acrylic emulsions and polyurethane.
[0034] Preparation Stage: The partition base plate 1 is in its unfolded state when shipped from the factory or in an unused condition. At this time, the limiting mechanism on the partition base plate ensures that it is in a fully unfolded state. This limiting mechanism can be implemented using simple external clamps or straps. These can be attached to the partition base plate 1 when it is unfolded, maintaining its unfolded state by physically restricting the bending of the partition base plate. Although the limiting elastic band 4 has already been installed, it is restrained by the limiting mechanism at this time.
[0035] Because the shelf base plate 1 is unfolded and secured by a limiting mechanism, it can be stacked together during transportation, saving space and reducing the risk of damage. Furthermore, this design facilitates storage until needed.
[0036] When shelf folding is required to accommodate specific storage needs, the limiting mechanism must first be removed or released. This step may involve simple physical operations, such as unfastening fasteners or straps, depending on the actual design.
[0037] Once the limiting mechanism is removed, the limiting elastic band 4 begins to function. The limiting elastic band is hung on both sides of the elastic band hook 3, and passes through the elastic band slot 2 in the middle and is arranged in a crisscross pattern. Since the limiting elastic band is in a stretched state when the partition base plate is unfolded, when the limiting mechanism is removed, the limiting elastic band 4 will attempt to return to its original shape through its elastic tension, thereby providing an inward folding force to both ends of the partition base plate 1.
[0038] As the force of the limiting elastic band 4 is applied to the spacer base plate 1, the spacer base plate begins to bend and form along the groove lines of the pre-grooved structure. The two parallel groove lines guide the spacer base plate to fold in a predetermined manner, ensuring that the entire process is smooth and meets the design requirements.
[0039] like Figure 5 As shown, a refrigerator storage cabinet includes a cabinet body 8, a shelf 9, and the aforementioned shelf. A placement slot 81 is formed on the cabinet body 8, and the shelf 9 is slidably connected to the placement slot 81 and slidably connected to the shelf plate slot 7. The shelf plate slot 7 corresponds to the position of the shelf 9.
[0040] After being folded, the shelf can be placed in the designated location inside the refrigerator cabinet. The shelf 9 is slidably connected to the placement slot 81 opened in the cabinet body 8, and corresponds to the position of the shelf slot 7, ensuring that the shelf can be stably installed in the required position.
[0041] It should be noted that the limiting mechanism and the limiting rubber band 4 in this embodiment are general standard parts or components known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods.
[0042] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
