[0029] The shelf of the traditional refrigerator is usually made of plastic material, which has certain lightness and cost advantage, but is easy to deform in the process of long-term bearing heavy pressure and frequent use. In addition, the connection mode between the shelf and the inner container is relatively simple, which is generally matched by the support points at both ends of the shelf and the clamping grooves at the edge of the inner container. This structure is easy to cause the gap between the shelf and the inner container to increase due to the deformation of the shelf and the slight deformation of the inner container after long-term use. Moreover, with the extension of the use time, the deformation degree of the shelf may gradually increase, further aggravating the increase of the gap, so that the shelf shakes and is unstable during use, which brings many inconveniences to the user.
[0030] Therefore, the utility model provides a shelf support assembly to solve the above problems.
[0031] Please refer to Figure 1 , Figure 2 and Figure 3 As shown in the drawings, in an embodiment of the utility model, the shelf support assembly is installed on the inner container 2 of the refrigerator. The shelf support assembly comprises a shelf support plate 20, a shelf assembly 10 and at least two reinforcing metal plates 30. The shelf support plate 20 has a support arm 21 extending along the front-rear direction of the refrigerator. The shelf assembly 10 is installed on the shelf support plate 20. The at least two reinforcing metal plates 30 are respectively fixedly installed on the two support arms 21, and the reinforcing metal plates 30 extend along the front-rear direction of the refrigerator. The support arm comprises a connecting mounting plate, an extension plate and a positioning plate, the extension plate extends downward from the mounting plate, and the mounting plate is arranged away from the positioning plate.
[0032] Specifically, the shelf support assembly is mounted on the inner container 2 of the refrigerator, used to separate the space of the inner container 2 of the refrigerator, and facilitate the user to layout and use the space in the refrigerator. It should be noted that the inner container 2 is arranged along the height direction of the refrigerator. Each group of slide grooves can place the shelf support assembly 1 of the present application. The user can judge according to the volume of the food put in to select the slide groove where the shelf support assembly 1 is placed, so as to adjust the space layout in the inner container 2. The shelf support assembly includes a shelf support plate 20, a shelf assembly 10 and at least two reinforcing metal plates 30. The shelf support plate 20 is the core component of the entire shelf support assembly, which carries the shelf assembly 10 and can be mounted on the slide groove in the inner container 2 of the refrigerator. The shelf support plate 20 has two support arms 21 which are arranged in parallel and extend along the front-to-back direction of the refrigerator. The shelf support plate 20 is matched with the slide groove on the inner container 2 of the refrigerator through the two support arms 21 on its sides, so as to realize the sliding function of the shelf support plate 20 on the slide groove, so as to slide the shelf support plate to the innermost side, and the sliding direction is the front-to-back direction of the refrigerator.
[0033] The shelf assembly 10 is horizontally mounted on the shelf support plate 20 and used to directly place food. The at least two reinforcing metal plates 30 are respectively fixedly installed on the two support arms 21, and the reinforcing metal plates 30 extend along the front-to-back direction of the refrigerator. The reinforcing metal plates 30 are arranged to enhance the mechanical strength of the shelf support plate 20 and prevent the shelf support plate 20 from deforming when used for a long time or bearing a large weight. By arranging the reinforcing metal plates 30 on each support arm 21, the pressure borne by the two support arms 21 of the shelf support plate 20 can be effectively dispersed, the carrying capacity and stability of the shelf support plate 20 are improved, and the service life of the shelf support assembly is prolonged. The fixing mode between the reinforcing metal plate 30 and the support arm 21 can be embedded, pre-buried injection molding, riveting or screw connection, etc., to ensure that the connection between the reinforcing metal plate 30 and the support arm 21 is firm and reliable, thereby playing its reinforcing role.
[0034] Through the above design, the shelf support assembly of the present embodiment can not only be conveniently mounted on the inner container 2 of the refrigerator, but also can be flexibly adjusted according to the needs of the user to realize the effective separation and utilization of the space in the refrigerator. At the same time, the arrangement of the reinforcing metal plate 30 effectively improves the strength and stability of the shelf support plate 20, so that the shelf support assembly can better bear the food and avoid the use problems caused by deformation, thereby improving the user's experience.
[0035] The support arm 21 comprises an integral mounting plate 211, an extension plate 212 and a positioning plate 213. The mounting plate 211 is in the shape of a straight strip, and the direction in which the mounting plate 211 extends is the front-to-rear direction of the refrigerator. The two support arms 21 are each provided with a mounting plate 211, which is respectively slid in the slide groove on the two sides of the inner container 2 of the refrigerator, so that the shelf support plate 20 can be moved to the innermost position of the inner container. The upper end of the extension plate 212 is connected to the mounting plate 211, and the lower end extends downward. The length of the extension plate 212 in the up-and-down direction is much smaller than the length of the extension plate 212 in the front-to-rear direction of the refrigerator, and the length of the extension plate 212 in the front-to-rear direction of the refrigerator is approximately equal to the length of the support arm 21. The extension plate 212 is located on the side of the extension plate away from the mounting plate, and the extension plate protrudes outwardly to the positioning plate 213. The positioning plate 213 and the extension plate 212 form a receiving groove 214 that accommodates the first reinforcing plate 31. When the positioning plate 213 is installed, the reinforcing metal plate 30 can be directly accommodated in the receiving groove, which facilitates the assembly of the work personnel and the corresponding fixing work. Furthermore, the positioning plate 213 can also increase the mechanical strength of the support arm 21 and further improve its anti-deformation capability.
[0036] When the shelf support assembly 1 of the present application is used for a long time, the support arm 21 is prone to deformation due to continuous sliding friction and the load of food. In particular, the mounting plate 211 is the part that is most prone to deformation during use, as it serves as the sliding part and contacts the inner container 2. The present application successfully enhances the mechanical strength of the support arm 21 and improves its anti-deformation capability by providing a reinforcing metal block below the mounting plate 211, and the reinforcing metal block extends in the same direction as the mounting plate 211. This design not only prolongs the service life of the support arm 21, but also ensures the stability of the entire structure. Furthermore, the mounting plate 211 usually needs to match the inner container 2, and the size of the slide groove on the inner container 2 is relatively narrow, so the reinforcing metal plate is not suitable for being arranged on the mounting plate 211.
[0037] Further, the extension plate 212 is arranged in a spaced manner with the mounting plate 211. In this embodiment, the extension plate 212 and the mounting plate 211 have a certain distance or gap therebetween. The spaced arrangement provides a larger movement space for the mounting plate 211, making the sliding of the mounting plate 211 in the slide groove of the inner container 2 more smooth. At the same time, this also allows the support arm 21 to have a certain elastic deformation space when subjected to lateral force, thereby increasing the overall flexibility of the support arm 21.
[0038] Further, as shown in Figure 4 the reinforcing metal plate 30 is in the shape of an L, which comprises a first reinforcing plate 31 and a second reinforcing plate 32 connected to each other,
[0039] Specifically, in this embodiment, the reinforcing metal plate 30 is designed in L shape, consisting of a first reinforcing plate 31 and a second reinforcing plate 32 connected together. This design provides reinforcing effect in two directions, both enhancing the vertical supporting force and increasing the horizontal stability. On the outer side of the extension plate 212, a protruding positioning plate 213 is designed. This positioning plate 213 forms a containing groove 214 with the extension plate 212 itself, which is specially designed to accommodate the first reinforcing plate 31. The design of the containing groove 214 enables the L-shaped reinforcing metal plate 30 to be accurately installed on the extension plate 212, and ensures that it can stably function when subjected to load. It is to be noted that the second reinforcing plate 32 can be partially arranged in the containing groove, or can be entirely arranged in the containing groove. When the length of the protrusion of the positioning plate 213 to the outer side is longer, the second reinforcing plate 32 can be entirely accommodated in the containing groove 214, and when the protrusion of the positioning plate 213 to the outer side is shorter, the second reinforcing plate 32 can be partially accommodated in the containing groove 214.
[0040] In the installation, the first reinforcing plate 31 of the L-shaped reinforcing metal plate 30 is partially arranged below the extension plate 212, while the second reinforcing plate 32 is attached to the inner side of the positioning plate 213. In this way, the entire L-shaped reinforcing metal plate 30 is firmly installed in the containing groove 214. Through this installation method, the L-shaped reinforcing metal plate 30 not only provides additional vertical supporting force for the extension plate 212, but also increases the horizontal stability through the second reinforcing plate 32. This is of great significance to prevent the supporting arm 21 from being deformed or damaged after long-term use. This design not only improves the mechanical strength and stability of the supporting arm 21, but also ensures the compactness of the structure and the ease of installation.
[0041] Further, the positioning plate 213 is located at the lower end of the extension plate 212; the first reinforcing plate 31 is attached to the extension plate 212, and the second reinforcing plate 32 is attached to the positioning plate 213.
[0042] Specifically, in this embodiment, the positioning plate 213 is protruded outward from the bottom wall edge of the extension plate 212, which forms a receiving space between the positioning plate 213 and the extension plate 212, and this space is used to install the L-shaped metal reinforcing metal plate 30. The positioning plate 213 is perpendicular to the extension plate 212, which can increase the mechanical strength of the entire connecting arm. The first reinforcing plate 31 is closely attached to the surface of the extension plate 212, which ensures that the first reinforcing plate 31 can effectively transfer and disperse the load from the extension plate 212, thereby increasing the vertical supporting force of the support arm 21. The second reinforcing plate 32 is attached to the inner surface of the positioning plate 213, which can increase the stability of the support arm 21 in the horizontal direction and prevent it from deforming laterally. The positioning plate 213 is arranged at the lower end of the extension plate 212, which can significantly increase the structural strength of the extension plate 212, and the positioning plate 213 also provides a stable reference surface for installing and fixing the metal reinforcing metal plate 30, and participates in forming the receiving space with the extension plate 212. It should be noted that the close attachment refers to the surface of the reinforcing metal plate 30 being attached to the surface of the extension plate 212 and the surface of the positioning plate 213, thereby increasing the contact area between them, which can increase the mechanical strength of the metal reinforcing metal plate 30 to the extension plate 212 and the positioning plate 213, and prevent the entire support arm 21 from deforming over a long period of use.
[0043] Further, the shelf bracket assembly 1 further comprises a locking member 40 for fixing the first reinforcing plate 31 to the extension plate 212; and / or for fixing the second reinforcing plate 32 to the positioning plate 213.
[0044] Specifically, the main function of the locking member 40 is to firmly fix the first reinforcing plate 31 to the extension plate 212, and / or to fix the second reinforcing plate 32 to the positioning plate 213. This fixing method ensures that the reinforcing metal plate 30 will not loosen or shift when subjected to load, thereby ensuring the overall stability and strength of the support arm 21. During installation, pre-drilled mounting holes are made on the reinforcing metal plate 30 to align with the corresponding holes on the extension plate 212 or the positioning plate 213. The locking member 40 (such as a bolt) is inserted through the mounting hole on the reinforcing metal plate 30 and screwed into the extension plate 212 or the positioning plate 213. In this embodiment, by introducing the locking member 40, the structural strength of the shelf bracket assembly 1 is further improved. The tightening action of the locking member 40 ensures the firm connection between the reinforcing metal plate 30 and the extension plate 212, the positioning plate 213, thereby enhancing the anti-deformation ability and stability of the entire support arm 21.
[0045] Further, the ratio of the length of the reinforcing metal plate 30 to the length of the support arm 21 is within the range of 1 / 2-3 / 4.
[0046] Specifically, in the design of the shelf support assembly 1, the ratio of the length of the reinforcing metal plate 30 to the length of the support arm 21 is a key parameter that directly affects the stability and strength of the entire structure. The main role of the reinforcing metal plate 30 is to increase the structural strength of the support arm 21 to prevent it from deforming under load. When the ratio of the length of the reinforcing metal plate 30 to the length of the support arm 21 is within the range of 1 / 2 to 3 / 4, the stress from the load can be effectively dispersed and resisted, thereby improving the stability of the entire structure. Within this ratio range, the reinforcing metal plate 30 can provide sufficient support force without causing excessive waste of materials. This helps to reduce production costs and improve the cost-effectiveness of the product. The length of the reinforcing metal plate 30 is the length in the front-to-rear direction of the refrigerator, and the length of the reinforcing metal plate is also the length in the front-to-rear direction of the refrigerator.
[0047] Further, the material of the reinforcing metal plate 30 is any one of aluminum alloy, stainless steel, copper alloy, magnesium alloy, and galvanized steel plate.
[0048] Specifically, in the design of the shelf support assembly 1, the selection of aluminum alloy, stainless steel, copper alloy, magnesium alloy, and galvanized steel plate as the material of the reinforcing metal plate 30 is based on a comprehensive consideration of various factors, including the mechanical properties, corrosion resistance, cost-effectiveness, and processability of the materials. Aluminum alloy has the characteristics of low density and high strength, which enables it to significantly reduce the weight of the entire shelf support assembly 1 while ensuring structural strength, facilitating handling and installation. The aluminum alloy surface can form a dense oxide film, effectively resisting the corrosion of atmosphere, water, and most chemicals, prolonging the service life of the shelf support assembly 1. Aluminum alloy is easy to cut, bend, weld, and surface treat, which is conducive to the processing of complex shapes and structures, meeting the diversified design requirements. Stainless steel has excellent corrosion resistance and can maintain the stability of its structure and performance in harsh environmental conditions (such as high temperature, high humidity, and strong corrosive media). Stainless steel has high strength and hardness, capable of withstanding large loads and impacts, ensuring the stability and safety of the shelf support assembly 1. Galvanized steel plate improves its corrosion resistance by plating a layer of zinc on the surface of the steel plate, which can extend the service life of the shelf support assembly. Copper alloy has good corrosion resistance and high strength and hardness, capable of withstanding large pressures and abrasion. The density of magnesium alloy is much lower than that of many other metals, such as steel and aluminum alloy, which enables it to significantly reduce weight while ensuring strength.
[0049] Further, please refer to Figure 4 and Figure 5 , the shelf support assembly 1 further comprises a support piece 50, which is used to be installed on the inner container 2 and to support the support arm 21. The lower end of each of the two support arms 21 has a hanging groove 215 for the insertion of the support piece 50.
[0050] Specifically, the length of the slide groove in the inner container 2 of the refrigerator is usually short, and therefore the support arm 21 may be unstable in the short slide groove, and therefore the present application provides a special support 50 to support the support arm 21, which is an effective solution. The main function of the support 50 is to provide additional support force to ensure that the support arm 21 remains stable in the slide groove. Through reasonable structural design, the support 50 can effectively prevent the support arm 21 from shaking or tilting when sliding or under stress. The support 50 is installed on the inner container 2 to provide a stable support point. It can be a simple metal rod, bracket or plate, etc. In the present embodiment, the support 50 is used to support the end of the support arm 21 close to the refrigerator door to ensure that the support arm 21 can be stably supported. The number of supports 50 is two, and each lower end of the two support arms 21 is provided with a hooking groove 215. The hooking groove 215 is located at the outer end of the support arm 21, and the support 50 is inserted into the hooking groove 215 to top the outer end of the support arm 21 against the inner container 2, thereby providing additional support force to ensure that the support arm 21 remains stable in the slide groove.
[0051] Further, the support 50 includes a bottom plate 51, a hook 52, and a sponge tape, the hook 52 is integrally connected to the bottom plate 51 for passing through the inner container 2 and extending to the support arm 21, and the sponge tape 53 is connected to the bottom plate 51 and adheres to the inner container 2 at the other end.
[0052] Specifically, the inner container 2 is provided with a through hole corresponding to the position below the hooking groove 215, and the support 50 passes through the through hole to extend into the position of the hooking groove 215 and hook the hooking groove 215. The support 50 includes an integral bottom plate 51 and hook 52, and a sponge tape 53 adhered to the bottom plate 51. The bottom plate 51 serves as the basic part of the support 50, and provides a stable support surface so that the entire support 50 can be firmly installed on the inner container 2. The hook 52 is the core part of the support 50, which is integrally connected to the bottom plate 51 and designed with appropriate length and shape to pass through the inner container 2 and extend into the hooking groove 215 of the support arm 21. The sponge tape 53 is used to increase the buffer between the support 50 and the inner container 2, and has one end connected to the bottom plate 51 and adhered to the inner container 2. The softness and elasticity of the sponge can effectively absorb vibration and impact force, protecting the inner container 2 from damage. At the same time, the sponge can also fill the small gap between the bottom plate 51 and the inner container 2, improving the tightness and stability of the installation.
[0053] The utility model also proposes a kind of refrigerator, and the refrigerator includes shelf support assembly, and the specific structure of the shelf support assembly refers to above-mentioned embodiment, since the refrigerator of the present application adopts all technical solutions of above-mentioned embodiment, at least has all beneficial effects brought by the technical scheme of above-mentioned embodiment, which will not be repeated here.
