Description

Technical Field

[0001] The utility model relates to the technical field of cabinet storage, and in particular to a swing-arm type lifting storage basket. Background Art

[0002] As modern home life demands increased kitchen space utilization and convenience, liftable kitchen racks have become an ideal choice for kitchen storage. Among existing technical solutions, Chinese utility model patent No. CN109431118A discloses a liftable kitchen rack that includes a lift-limiting assembly and a basket connected to a movable end of the lift-limiting assembly. The basket is provided with a push-pull member for hand-operated force application. The lift-limiting assembly comprises a first swing arm and a second swing arm, each of which has a distal end hinged to the side wall of the basket. The proximal end of the first swing arm is hingedly disposed within the lift-limiting assembly, and the proximal end of the second swing arm is movable within the lift-limiting assembly along a predetermined curved path. The second swing arm can be positioned at both ends of the curved path.

[0003] However, this existing lifting storage kitchen rack has exposed some shortcomings during actual use.

[0004] On the one hand, the structural design of this kitchen rack has flaws in the way the basket side panels are fixed. The fixing nails for the basket side panels are mostly exposed, which is highly undesirable from an aesthetic perspective. As a key space in the home, users often expect the furniture and fixtures therein to have a good appearance. However, the exposed fixing nails severely impact the overall aesthetics of the kitchen rack. Furthermore, from the perspective of practicality and durability, the exposed fixing nails are highly susceptible to rusting due to the unique characteristics of the kitchen environment, including moisture, oil, and other factors. Once rusted, not only does it affect the structural strength of the fixing nails themselves, but it can also cause corrosion and other damage to the attached basket side panels, significantly shortening the service life of the basket side panels and increasing repair and replacement costs.

[0005] On the other hand, in terms of the power assist system, the lifting and limiting assembly in this patent only uses a telescopic cylinder as a power assist component to push the cabinet basket back up. This single power assist method has obvious limitations. In actual kitchen storage scenarios, the weight of the items placed in the cabinet basket can vary greatly. The power assist provided by the telescopic cylinder is limited and fixed, and it is not possible to flexibly select the appropriate power assist size according to the weight of the objects in the cabinet basket. When heavier items are placed in the cabinet basket, insufficient power assist may occur, causing the user to expend greater effort when pushing the cabinet basket back up, which is very inconvenient to operate; and when the items in the cabinet basket are lighter, the fixed power assist may cause energy waste or generate unnecessary impact force, affecting the service life of the kitchen rack.

[0006] In summary, in view of these problems existing in the prior art, it is necessary to develop a new lifting storage kitchen rack to overcome the above defects and meet people's needs for the aesthetics, durability and ease of operation of kitchen storage racks. Utility Model Content

DETAILED DESCRIPTION

[0035] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments, wherein the same components are represented by the same reference numerals.

[0036] Example 1

[0037] See also Figures 1 to 3 An embodiment of the utility model discloses a swing arm type lifting storage basket, including a swing arm mechanism 10 and a storage basket 20.

[0038] like Figure 1 As shown, there are two swing arm mechanisms 10, symmetrically mounted on the left and right side walls of the cabinet. The storage basket 20 includes an upper basket body 21, a lower basket body 22, an outer guard plate 23, and an inner baffle 24. The upper basket body 21 and the lower basket body 22 are spaced apart vertically. Both the upper basket body 21 and the lower basket body 22 are used to store items. There is at least one upper basket body 21 and one lower basket body 22. Typically, due to cabinet space limitations, there are only one upper basket body 21 and one lower basket body 22. Both the outer guard plate 23 and the inner baffle 24 are two pieces. The upper sides of the two inner baffles 24 are fixed to the two side walls of the upper basket body 21, and the lower sides of the two inner baffles 24 are fixed to the two side walls of the lower basket body 22. The two outer guard plates 23 wrap around the outer side surfaces and edges of the two inner baffles 24.

[0039] The swing-arm lifting storage basket of this embodiment, by providing an outer guard plate 23, effectively shields the fixing pins connecting the upper basket body 21, the lower basket body 22, and the inner baffle 24. On the one hand, this significantly reduces the exposed portion of the fixing pins, making the overall appearance of the storage basket 20 more neat and coordinated, greatly enhancing its aesthetics. On the other hand, the shielding provided by the outer guard plate 23 prevents the fixing pins from being directly exposed to the external environment, reducing the chance of the fixing pins coming into contact with moisture, dust, oil, and other substances, thereby effectively preventing the fixing pins from rusting and corroding, extending the service life of the fixing pins and the components connected to them, indirectly improving the durability of the entire storage basket 20, and reducing the frequency of repairs or component replacements due to damaged fixing pins. This optimizes the performance of the swing-arm lifting storage basket in multiple aspects.

[0040] In this embodiment, the material of the outer guard plate 23 is ABS, and the outer side of the outer guard plate 23 has decorative stripes. ABS has good chemical resistance, heat resistance, impact resistance, glossiness and a certain hardness, and can better protect the inner baffle 24.

[0041] In this embodiment, a plurality of hollow columns 231 are evenly distributed on the inner side surface of the outer guard plate 23, and the inner baffle plate 24 is provided with conical holes 241 corresponding to the hollow columns 231 one by one. The outer guard plate 23 is fixed to the inner baffle plate 24 by screws passing through the conical holes 241 and embedded in the hollow columns 231. The hollow columns 231 are evenly arranged around the edge of the outer guard plate 23 vertically and horizontally. The combination of the conical holes 241, the hollow columns 231 and the screws makes the outer guard plate 23 more stable when assembled on the inner baffle plate 24.

[0042] In this embodiment, positioning holes 242 are provided at intervals above and below the inner baffle plate 24 at positions corresponding to the rear side plates of the upper basket body 21 and the lower basket body 22. The positioning holes 242 can extend in the length direction of the upper basket body 21 and the lower basket body 22, so that the depth of the positioning holes 242 reaches more than 3 mm. The inner side surface of the outer guard plate 23 is provided with positioning blocks 232 that correspond one-to-one to the positioning holes 242. The positioning blocks 232 are inserted into the positioning holes 242 to align the tapered holes 241 with the hollow columns 231, thereby facilitating the assembly of the outer guard plate 23.

[0043] Example 2

[0044] like Figure 4 and Figure 5 As shown, this embodiment improves the structure of the swing arm mechanism 10 based on the embodiment 1.

[0045] The swing arm mechanism 10 includes a housing 11, a telescopic cylinder 12, a front short swing arm 131, a rear long swing arm 132, a connecting spring 141, a main spring 142 and a chain 151. The housing 11 is fixed to the inner wall of the cabinet. Specifically, the housing 11 is composed of an inner end plate 111, a frame 112 and an outer end plate 113. A first mounting post 114 is fixed to the middle of the inner end plate 111 of the housing 11, and a second mounting post 115 is fixed to the front lower part of the inner end plate 111. The second mounting post 115 is rotatable. A first guide sprocket 152 is sleeved thereon, a third mounting post 116 is fixedly provided on the rear lower portion of the inner end plate 111, a fourth mounting post 117 is provided on the rear upper portion of the inner end plate 111, a fifth mounting post 118 is fixedly provided on the front upper portion of the shell 11, and the fifth mounting post 118 is rotatably sleeved thereon with a second guide sprocket 153, and openings 1121 are provided on the front and upper sides of the shell 11 for the front short swing arm 131 and the rear long swing arm 132 to swing. Specifically, the opening 1121 is provided on the front and upper sides of the frame 112.

[0046] The upper end of the front short swing arm 131 and the upper end of the rear long swing arm 132 are respectively hinged to the upper part of the inner baffle 24 at a front-to-back interval. Specifically, a connecting column 16 is fixed to the inner baffle 24. The upper ends of the front short swing arm 131 and the rear long swing arm 132 are respectively connected to the two ends of the connecting column 16. More specifically, the outer guard plate 23 is provided with a screw through hole 234 for fixing the connecting column 16 and a guard edge 233 surrounding the screw through hole 234 and surrounding the connecting column 16. That is, the connecting column 16 is located in the guard edge 233, and the connecting column 16 is connected to the front short swing arm 131 and the rear long swing arm 132. The swing arm 132 is connected to the inner baffle 24 by screws passing through the screw holes 234. The provision of the guard edge 233 and the connecting column 16 can make the structure of the connection between the front short swing arm 131, the rear long swing arm 132 and the inner baffle 24 more compact and beautiful. The lower end of the front short swing arm 131 movably extends into the shell 11 through the opening 1121 and is hinged on the second mounting column 115. The lower end of the rear long swing arm 132 movably extends into the shell 11 through the opening 121 and is hinged on the first mounting column 114, so that the storage basket 20 can be extended into and out of the cabinet along a certain curved path.

[0047] A damping groove 119 is also provided in the shell 11, which slides with the lower end of the rear long swing arm 132. On the one hand, the provision of the damping groove can guide the rotation direction of the rear long swing arm 132; on the other hand, when the storage basket 20 is pulled down, the damping groove 119 will increase the resistance to the movement of the rear long swing arm 132, thereby increasing the resistance encountered by the storage basket 20 when it descends. This increase in resistance helps to keep the storage basket 20 in a straight position during the lifting and lowering process, thereby avoiding the phenomenon of items tipping over during this process.

[0048] In this embodiment, a handle 25 is provided in the middle of the front side of the lower basket body 22. By pulling the handle 25 downward, the storage basket 20 can be extended from the cabinet. By pushing the handle 25 upward, the storage basket 20 can be placed into the cabinet from the bottom of the cabinet. The storage basket 20 is raised and lowered by the swing arm mechanism 10 formed by the front short swing arm 131 and the rear long swing arm 132. The structure is simple and the technology is mature.

[0049] In this embodiment, the chain 151 cooperates with the first guide sprocket 152 and the second guide sprocket 153 respectively, and the upper end of the chain 151 is connected to the rear long swing arm 132, and the lower end of the chain 151 is connected to the third mounting post 116 via the connecting spring 141. One end of the main force spring 142 is connected to the fourth mounting post 117, and the other end of the main force spring 142 is connected to the rear long swing arm 132. The cylinder body of the telescopic cylinder 12 is hinged to the lower part of the front short swing arm 131, and the telescopic end of the telescopic cylinder 12 is hinged to the third mounting post 116.

[0050] When the storage basket 20 is pulled downward, the rear swing arm 132 rotates counterclockwise. At this point, the cylinder body of the telescopic cylinder 12 synchronizes with the rear swing arm 132 and also rotates counterclockwise. Because the telescopic end of the telescopic cylinder 12 is hinged to the third mounting post 116, it contracts during this rotation. Simultaneously, as the rear swing arm 132 is pulled, the chain 151 stretches the connecting spring 141; the swinging of the rear swing arm 132 also stretches the main spring 142. The arrangement of the telescopic cylinder 12, the connecting spring 141, and the main spring 142 is designed to balance the weight of the storage basket 20 itself and the weight of the items stored therein, ensuring smoother and more effortless operation when the storage basket 20 is pulled downward or pushed upward.

[0051] In this embodiment, when the storage basket 20 contains heavy objects, pressing the push lock 171 causes the hook of the push lock 171 to engage within the lock body 172, thereby locking the chain 151. When the storage basket 20 is pulled downward, the rear long swing arm 132 begins to rotate counterclockwise, and the cylinder body of the telescopic cylinder 12 rotates counterclockwise in sync with the rear long swing arm 132. During this process, the telescopic end of the telescopic cylinder 12 contracts. Since the chain 151 is locked, the secondary force spring 143 is stretched. Furthermore, the main force spring 142 is also stretched due to the swinging of the rear long swing arm 132. With the help of the settings of the press lock 171, the lock body 172 and the auxiliary force spring 143, when the storage basket 20 is loaded with heavier objects, the auxiliary force spring 143 with a larger spring coefficient can be activated to balance the gravity of the stored objects, so that the heavier storage basket 20 can be pushed up and pulled down more effortlessly, and the whole process is smoother.

[0052] In this embodiment, the auxiliary force spring 143, the main force spring 142, the main force spring 142, the first mounting column 114 and the telescopic cylinder 12 are arranged in sequence from top to bottom at the connection point with the rear long swing arm 132. Such an arrangement sequence can make the component layout inside the swing arm mechanism 10 more reasonable, the overall arrangement more neat, and can ensure that the components do not interfere with each other during operation, thereby improving the overall operation stability and reliability of the swing arm mechanism 10.

[0053] The above-mentioned technical scheme of the present invention is described in detail with reference to specific embodiments. The specific embodiments described are used to help understand the concept of the present invention. Derivations and modifications made by those skilled in the art based on the specific embodiments of the present invention also fall within the scope of protection of the present invention.
