Description
Technical Field
[0001] This utility model relates to the field of cabinet storage technology, specifically to a swing-arm lifting storage basket assembled inside a cabinet. Background Technology
[0002] With the continuous upgrading of modern home kitchen functions and the demand for efficient space utilization, lift-up storage racks, with their flexible access and space optimization features, have become a key component of intelligent kitchen storage systems. In the existing technical field, Chinese utility model patent CN2024224017380 discloses a swing-arm type lift-up storage basket assembled in a cabinet. This basket achieves its lifting function through a swing-arm mechanism composed of a shell, telescopic cylinder, front short swing arm, rear long swing arm, connecting spring, main spring, and chain. However, this swing-arm type lift-up storage basket has the following shortcomings in use:
[0003] When the chain is unlocked, the telescopic cylinder, connecting spring, and main spring reset synchronously during the basket's return process, generating a superimposed driving force that causes the basket to quickly enter the cabinet. When the chain is locked, the combined driving force formed by the reset of the telescopic cylinder, auxiliary spring, and main spring is further enhanced. Due to the lack of an effective damping or speed adjustment mechanism, the basket's return speed exhibits a non-linear surge. This dynamic characteristic easily causes items inside the basket to shake violently, slide, or even fall due to inertial forces, which not only reduces safety but also creates a technical gap in compatibility with the sophisticated storage needs of modern kitchens.
[0004] Given these problems in existing technologies, it is necessary to develop a new lift-up storage kitchen rack to overcome the aforementioned shortcomings. Utility Model Content
[0005] In view of this, this utility model proposes a swing-arm lifting storage basket that can be installed in a cabinet. By adding a telescopic rod, the storage basket can be returned to its original position smoothly, reducing the risk of items shifting or falling due to inertia during storage.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A swing-arm type lifting storage basket assembled in a cabinet includes a swing-arm mechanism and a storage basket. There are two swing-arm mechanisms, which are symmetrically installed on the left and right side walls inside the cabinet. Each swing-arm mechanism includes a housing, a telescopic cylinder, a front short swing arm, a rear long swing arm, a connecting spring, a main spring, and a chain.
[0008] The housing is fixed to the inner wall of the cabinet. A first mounting post is fixed to the middle of the inner end plate of the housing.

The two outer protective plates respectively wrap around the outer side and edge of the inner baffles.
[0018] Optionally, the swing arm mechanism further includes a push-button latch, a lock body, and a secondary force spring. One end of the secondary force spring is connected to the upper end of the chain, and the lower end of the secondary force spring is connected to the rear long swing arm. The stiffness coefficient of the secondary force spring is greater than that of the connecting spring. The push-button latch is fixedly inserted through the side of the housing, and the lock body is located in the middle of the chain. The locking hook of the push-button latch engages / disengages from the lock body to lock or unlock the chain.
[0019] Optionally, the connection points of the auxiliary force spring, the main force spring, the first mounting post, and the telescopic cylinder with the rear long swing arm are arranged sequentially from top to bottom.
[0020] Optionally, the housing is further provided with a damping groove that slides with the lower end of the rear long swing arm.
[0021] Optionally, the inner baffle is fixedly connected to a connecting column, and the upper ends of the front short swing arm and the rear long swing arm are respectively hinged to the two ends of the connecting column.
[0022] The beneficial effects of this utility model are:

Detailed Implementation
[0029] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.
[0030] Please see Figures 1 to 3 This utility model discloses a swing-arm type lifting storage basket assembled in a cabinet, including a swing-arm mechanism and a storage basket.
[0031] like Figure 1 As shown, there are two swing arm mechanisms, which are symmetrically installed on the left and right side walls inside the cabinet.
[0032] like Figure 2 and Figure 3 As shown, the swing arm mechanism 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 square frame 112, and an outer end plate 113. The edge of the outer end plate 113 is fitted with a thickened washer 1131. The thickened washer 1131 can be used to adapt to non-standard cabinets and cabinets with large length errors, so as to achieve seamless installation. A first mounting post 114 is fixed in the middle of the inner end plate 111 of the housing 11, a second mounting post 115 is fixed in the lower front part of the inner end plate 111, a first guide chain tooth 152 is rotatably sleeved on the second mounting post 115, a third mounting post 116 is fixed in the lower rear part of the inner end plate 111, a fourth mounting post 117 is provided in the upper rear part of the inner end plate 111, a fifth mounting post 118 is fixed in the upper front part of the housing 11, a second guide sprocket 153 is rotatably sleeved on the fifth mounting post 118, and openings 1121 are provided on the front and upper sides of the housing 11 for the front short swing arm 131 and the rear long swing arm 132 to swing. Specifically, the openings 1121 are provided on the front and upper sides of the frame 112.
[0033] The upper ends of the front short swing arm 131 and the rear long swing arm 132 are respectively hinged at intervals to the upper part of the side wall of the storage basket. The lower end of the front short swing arm 131 extends into the housing 11 from the opening 1121 and is hinged to the second mounting post 115. The lower end of the rear long swing arm 132 extends into the housing 11 from the opening 121 and is hinged to the first mounting post 114, so that the storage basket can extend into / out of the cabinet along a certain curved path.
[0034] Chain 151 is engaged with first guide chain tooth 152 and second guide sprocket 153 respectively, and the upper end of chain 151 is connected to the rear long swing arm 132. The lower end of chain 151 is connected to the third mounting post 116 through connecting spring 141. One end of main spring 142 is connected to the fourth mounting post 16, and the other end of main spring 142 is connected to the rear long swing arm 132. The cylinder body of telescopic cylinder 12 is hinged to the lower part of rear long swing arm 132, and the telescopic end of telescopic cylinder 12 is hinged to the third mounting post 116.
[0035] In the embodiments of this utility model, the above-mentioned structure in the swing arm mechanism is completely consistent with the swing arm mechanism structure in patent number CN2024224017380, which is entitled "A Swing Arm Lifting Storage Basket Assembled in a Cabinet".
[0036] In an embodiment of this utility model, a telescopic rod 18 is also provided inside the housing 11. The fixed end of the telescopic rod 18 is fixed in the upper rear part inside the housing 11, and the telescopic end of the telescopic rod 18 moves against the rear side wall of the long swing arm 132. When the storage basket moves into the cabinet, the rear long swing arm 132 pushes the telescopic end of the telescopic rod 18 to retract. When the storage basket moves out of the cabinet, the rear long swing arm 132 gradually disengages from the telescopic rod 18, and the telescopic end of the telescopic rod 18 gradually extends back to its original position.
[0037] In an embodiment of this utility model, a swing-arm type lifting storage basket installed in a cabinet has the following characteristics: when the storage basket is pulled down, the rear long swing arm 132 rotates counterclockwise around the first mounting post 114 and the front short swing arm 131 rotates counterclockwise around the second mounting post 115. At this time, the telescopic cylinder 12 also rotates counterclockwise. Because the telescopic end of the telescopic cylinder 12 is hinged to the third mounting post 116, during the aforementioned rotation, the telescopic end of the telescopic cylinder 12 will retract. At the same time, as the rear long swing arm 132 is pulled, the chain 151 drives the connecting spring 141 to stretch. The swing of the rear long swing arm 132 will also cause the main spring 142 to enter the stretched state. The rear long swing arm 132 gradually disengages from the telescopic rod 18, and the telescopic end of the telescopic rod 18 gradually extends back to its original position. The telescopic cylinder 12, the connecting spring 141, and the main spring 142 are designed to balance the weight of the storage basket itself and the weight of the stored items, so that the storage basket can operate more smoothly when it is pulled down or pushed up, and it is also easier to operate.
[0038] When the storage basket is pushed upward, the rear long swing arm 132 rotates clockwise around the first mounting post 114 and the front short swing arm 131 rotates clockwise around the second mounting post 115. The telescopic cylinder 12 also rotates clockwise. At this time, the telescopic end of the telescopic cylinder 12 returns to its original position and extends. The connecting spring 141 resets and drives the chain 151 to move. The main spring 142 resets and causes the storage basket to enter the cabinet. During this process, the rear long swing arm 132 pushes against the telescopic end of the telescopic rod 18 to retract. The telescopic rod 18 acts as a stop and decelerates the long swing arm 132 during this process, so that the storage basket returns to its original position smoothly, reducing the risk of items in the storage basket shifting or falling due to inertia during storage.
[0039] In the embodiments of this utility model, the telescopic rod 18 is preferably a hydraulic damping rod. The hydraulic damping rod has a mature structure and is easy to purchase. The square frame 112 of the housing 11 is integrally provided with a locking frame 1122. The fixed end of the telescopic rod 18 is locked in the locking frame 1122. The telescopic rod 18 is fixed by the locking frame, and there is no need to set up a separate fixing structure. Its structure is relatively simple.
[0040] like Figure 2 and Figure 3 As shown, the housing 11 is also provided with a damping groove 119 that slides with the lower end of the rear long swing arm 132. The damping groove 119 and the square frame 112 are an integral structure. On the one hand, the damping groove 119 can guide the rotation of the rear long swing arm 132; on the other hand, when the storage basket is pulled down, the damping groove 119 increases the resistance of the movement of the rear long swing arm 132, thereby increasing the resistance encountered by the storage basket when it descends. This increase in resistance helps to keep the storage basket upright during the lifting and lowering process, thereby preventing the items from tipping over during the process.
[0041] In this embodiment, the swing arm mechanism also includes a press lock 171, a lock body 172, and a secondary force spring 143. One end of the secondary force spring 143 is connected to the upper end of the chain 151, and the lower end of the secondary force spring 143 is connected to the rear long swing arm 132. The stiffness coefficient of the secondary force spring 143 is greater than that of the connecting spring 141. The press lock 171 is fixedly inserted through the side of the housing 11, and the lock body 172 is located in the middle of the chain 151. The locking hook of the press lock 171 engages / disengages from the lock body 172 to lock or unlock the chain 151.
[0042] When the storage basket contains a heavy object, pressing the latch 171 engages the hook of the latch 171, locking the chain 151. When the storage basket is pulled down, the rear long swing arm 132 rotates counterclockwise around the first mounting post 114, and the front short swing arm 131 rotates counterclockwise around the second mounting post 115, simultaneously rotating the telescopic cylinder 12 counterclockwise. During this process, the telescopic end of the telescopic cylinder 12 retracts, and because the chain 151 is locked, the secondary force spring 143 is stretched. Furthermore, due to the swinging action of the rear long swing arm 132, the main force spring 142 is also stretched. With the help of the push-lock 171, lock body 172 and auxiliary force spring 143, when the storage basket is loaded with a heavier object, the auxiliary force spring 143 with a larger stiffness coefficient can be used to balance the weight of the stored object, so that the heavier storage basket is easier to push up and pull down, and the whole process is more stable.
[0043] In this embodiment, the auxiliary force spring 143, the main force spring 142, the first mounting column 114, and the telescopic cylinder 12 are arranged in a top-to-bottom order at the connection point with the rear long swing arm 132. This arrangement makes the internal component layout of the swing arm mechanism more reasonable, the overall arrangement more neat, and ensures that the components do not interfere with each other during operation, thereby improving the overall operational stability and reliability of the swing arm mechanism.
[0044] In this embodiment, the storage basket includes an upper basket 21, a lower basket 22, an outer protective plate 23, and an inner baffle 24. The upper basket 21 and the lower basket 22 are arranged vertically at intervals. Both the upper basket 21 and the lower basket 22 are used to place items. There is at least one upper basket 21 and one lower basket 22. Typically, due to cabinet space limitations, there is only one upper basket 21 and one lower basket 22. There are two outer protective plates 23 and two inner baffles 24. The upper sides of the two inner baffles 24 are fixed to the two side walls of the upper basket 21, and the lower sides of the two inner baffles 24 are fixed to the two side walls of the lower basket 22. The two outer protective plates 23 respectively wrap around the outer side and edge of the two inner baffles 24.
[0045] A handle 25 is provided on the front middle of the lower basket body 22. By pulling the handle 25 downward, the storage basket can be extended out of the cabinet. By pushing the handle 25 upward, the storage basket can be placed into the cabinet from below. The storage basket is raised and lowered by the swing arm mechanism formed by the front short swing arm 131 and the rear long swing arm 132. Its structure is simple and the technology is mature.
[0046] In an embodiment of this utility model, a connecting post 16 is fixedly connected to the inner baffle 24, and the upper ends of the front short swing arm 131 and the rear long swing arm 132 are respectively hinged to the two ends of the connecting post 16. The connection post 16 can make the structure at the connection between the front short swing arm 131, the rear long swing arm 132 and the inner baffle 24 more compact and beautiful.
[0047] The technical solution of this utility model has been described in detail above with reference to specific embodiments. The specific embodiments described are used to help understand the concept of this utility model. Derivations and modifications made by those skilled in the art based on the specific embodiments of this utility model also fall within the protection scope of this utility model.
