Description

Technical Field

[0001] This utility model relates to the technical field of pull-out basket assemblies, specifically to a pull-out basket assembly and a lift-up cabinet using the pull-out basket assembly. Background Technology

[0002] As an indispensable part of the kitchen, kitchen cabinets have undergone significant evolution in design and functionality over time. From early simple wooden cabinets to modern, intelligent, customized cabinet systems, the development of kitchen cabinets not only reflects technological progress but also embodies people's ever-increasing demands for kitchen space utilization and aesthetics. In modern kitchen design, kitchen cabinets are no longer just storage tools but also important elements that integrate functionality, practicality, and aesthetics.

[0003] In modern kitchen design, the functionality and practicality of cabinets have become a key focus for users. Traditional lift-up cabinets, especially for storing spice bottles, have some significant inconveniences. These cabinets usually only have openings or access hatches on the front, requiring users to walk around to the front of the cabinet to retrieve spice bottles.

[0004] Specifically, when users are busy in the kitchen and their hands or other parts of their body are occupied, they need to go around to the front of the cabinet to get the condiment bottle, which increases unnecessary actions and time costs. Utility Model Content

[0005] The purpose of this utility model is to provide a pull-out basket assembly and a lift-up cabinet using the pull-out basket assembly, so as to solve the problem that when users are busy in the kitchen and their hands or other parts of their body are occupied, they need to go around to the front of the cabinet to get the condiment bottle, which increases unnecessary actions and time costs.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a pull-out basket assembly, including a connecting rod, with sliding blocks that can slide up and down on the left and right sides of the connecting rod, a connecting plate connected to the bottom of the sliding block, a transmission plate connected to the top of the sliding block, a lead screw rotatably installed inside the connecting rod, an integrated box connected to the top of the connecting rod, a drive motor installed inside the integrated box, the output end of the drive motor being connected to the top of the lead screw via a pair of meshing gears, a connecting block threadedly connected to the lead screw, and the connecting block being fixedly connected to the rear side of the transmission plate.

[0007] Preferably, two fixing plates are fixed to the rear side of the connecting rod, and limiting blocks are provided on the left and right sides of the fixing plates respectively. The limiting blocks are in contact with the side of the sliding block to limit its displacement direction.

[0008] Preferably, the top and bottom ends of the lead screw are rotatably connected to the inner wall of the connecting rod via bearing seats.

[0009] Preferably, the meshing gear is a helical gear.

[0010] Preferably, a first stabilizing block is connected between the two fixed plates, and two stabilizing columns are respectively connected to the transmission plate and the connecting plate. Each pair of upper and lower stabilizing columns forms a group, and a second stabilizing block is connected between each group of stabilizing columns. The second stabilizing block is in contact with the side of the first stabilizing block to limit its displacement direction.

[0011] This utility model also discloses a liftable cabinet, including a cabinet and the pull-out basket assembly. The bottom surface of the cabinet is provided with a vertically movable placement plate. The placement plate is connected to the pull-out basket assembly through a connecting plate. The bottom surfaces on the left and right sides of the cabinet are provided with receiving openings to accommodate the thickness of the placement plate.

[0012] Preferably, a steel plate is embedded inside the placement plate, and the steel plate is fixedly connected to the front side of the connecting plate by bolts.

[0013] Compared with existing technologies, a pull-out basket assembly adopting the above technical solution has the following beneficial effects:

[0014] 1. By utilizing the single-sided connection structure of the connecting plate and the three-sided open layout of the placement plate, the limitation of traditional lift cabinets that only allow access from the front is overcome. When the drive motor drives the lead screw through the helical gear set, the connecting plate lifts the placement plate vertically, allowing users to directly access items from the front and both sides within a 270° range. This design significantly reduces the complexity of the operation, making it particularly suitable for kitchen work scenarios where both hands are restricted (such as when holding a pot), improving retrieval efficiency by over 40%.

[0015] Second, by designing the shelf as a movable structure and connecting it to the pull-out basket assembly, the cabinet's internal items can be lifted and lowered, improving space utilization and user convenience. Simultaneously, a steel plate is embedded inside the shelf and fixed to the transmission plate with bolts, enhancing the shelf's structural strength and stability, ensuring smooth operation during lifting and lowering, and preventing deformation or damage. Furthermore, the receiving opening provides space for the shelf, allowing it to be integrated seamlessly with the cabinet, improving the overall aesthetics. Attached Figure Description

Detailed Implementation

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figures 1-5 As shown, a pull-out basket assembly includes a connecting rod 1. Sliding blocks 2, which can slide up and down along the connecting rod 1, are respectively provided on the left and right sides of the connecting rod 1. A connecting plate 4 is connected to the bottom of the sliding block 2, and a transmission plate 3 is connected to the top of the sliding block 2. A lead screw 5 is rotatably installed inside the connecting rod 1. An integrated box 6 is connected to the top of the connecting rod 1. A drive motor 7 is installed inside the integrated box 6. The output end of the drive motor 7 is connected to the top of the lead screw 5 via a pair of meshing gears, which are helical gears. A connecting block 8 is threaded onto the lead screw 5, and the connecting block 8 is fixedly connected to the rear side of the transmission plate 3.

[0025] In use, the user starts the drive motor 7, whose output end transmits rotational motion to the lead screw 5 through a pair of meshing helical gears. When the lead screw 5 rotates, the two ends of the connecting block 8 are restricted by the connecting rod 1, causing the connecting block 8 to move axially (up and down) along the lead screw 5, thus converting the rotational motion into linear motion. When the connecting block 8 moves, it drives the transmission plate 3 to move synchronously. Through the movement of the transmission plate 3, the two sliding blocks 2 can be driven to slide, and the connecting plate 4 will also move synchronously. As the connecting plate 4 moves up and down, the placement plate 14 can be raised and lowered.

[0026] By utilizing the single-sided connection structure of the connecting plate 4 and the three-sided open layout of the placement plate 14, the limitation of traditional lift cabinets 13, which only allow access to items from the front, is overcome. When the drive motor 7 drives the lead screw 5 via the helical gear set, the connecting plate 4 causes the placement plate 14 to rise and fall vertically, allowing users to directly access items from the front and both sides within a 270° range. This design significantly reduces the complexity of the operational flow, making it particularly suitable for kitchen operations where both hands are restricted (such as when holding a pot), improving retrieval efficiency by over 40%.

[0027] like Figures 1-4As shown, two fixing plates 9 are fixed to the rear side of the connecting rod 1. Limiting blocks 10 are provided on the left and right sides of the fixing plates 9 respectively. The limiting blocks 10 fit against the side of the sliding block 2 to limit its displacement direction. The top and bottom ends of the lead screw 5 are rotatably connected to the inner wall of the connecting rod 1 through the bearing seat 11 respectively. Both the limiting blocks 10 and the sliding block 2 are provided with self-lubricating bushings (such as PTFE coating) to ensure that the coefficient of friction is reduced.

[0028] During use, the vertical displacement is achieved through the cooperation between the limit block 10 and the sliding block 2. This ensures a smoother lifting and lowering process, effectively preventing any shaking and thus improving the stability and reliability of the entire pull-out basket assembly.

[0029] like Figures 1-3 As shown, a first stabilizing block 16 is connected between the two fixed plates 9. Two stabilizing columns 17 are respectively connected to the transmission plate 3 and the connecting plate 4. Each pair of upper and lower stabilizing columns 17 forms a group. A second stabilizing block 18 is connected between each group of stabilizing columns 17. The second stabilizing block 18 is in contact with the side of the first stabilizing block 16 to limit its displacement direction. Both the first stabilizing block 16 and the second stabilizing block 18 are provided with self-lubricating bushings (such as PTFE coating).

[0030] In use, the two fixed plates 9 together support the two first stabilizing blocks 16, the first stabilizing blocks 16 further support the second stabilizing blocks 18, and the second stabilizing blocks 18 support several stabilizing columns 17. The two upper stabilizing columns 17 are used to support the transmission plate 3, and the two lower stabilizing columns 17 are used to support the connecting plate 4. The stabilizing columns 17 enhance the support strength of the middle part of the transmission plate 3 and the connecting plate 4, so that it can maintain a stable structural shape during the load-bearing process.

[0031] It should be noted that the sliding block 2, the limiting block 10, the first stabilizing plate 16, and the second stabilizing plate 18 are all connected to the slider via guide rails.

[0032] Example 2

[0033] like Figures 1-5 As shown, this utility model also discloses a liftable cabinet, including a cabinet 13 and a pull-out basket assembly. The bottom surface of the cabinet 13 is provided with a vertically movable placement plate 14. The placement plate 14 is connected to the pull-out basket assembly through a connecting plate 4. The bottom surfaces on the left and right sides of the cabinet 13 are provided with receiving openings 12 to accommodate the thickness of the placement plate 14. A steel plate 15 is embedded inside the placement plate 14, and the steel plate 15 is fixedly connected to the front side of the transmission plate 3 by bolts.

[0034] In use, by designing the placement plate 14 as a vertically movable structure and connecting it to the pull-out basket assembly, the lifting function of items inside the cabinet 13 is realized, improving space utilization and the convenience of users accessing items. At the same time, a steel plate 15 is embedded inside the placement plate 14 and fixedly connected to the connecting plate 4 with bolts, which enhances the structural strength and stability of the placement plate 14, ensuring that it remains stable during lifting and lowering and is not easily deformed or damaged.

[0035] In addition, the receiving opening 12 provides space for the placement board 14, ensuring that the placement board 14 can be integrated with the cabinet 13, thereby improving the overall aesthetics of the cabinet 13;

[0036] It is important to note that the pull-out basket assembly is rigidly anchored to the wall via bolt holes in the fixing plate 9. Cabinet 13 is fixed to the wall using coaxial embedded parts, forming a composite load-bearing system. All components of the pull-out basket assembly are embedded within the cabinet 13 cavity, achieving a concealed movement mechanism (this device needs to be customized according to the cabinet's internal height). The original bottom plate of cabinet 13 is replaced with a movable placement plate 14, which combines lifting functionality with the structural function of cabinet 13. The fixing plate 9 and the cabinet back panel are installed on the same plane. The pull-out basket transmission system (screw 5 / connecting block 8) is laid out along the centerline of the cabinet 13 back panel.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
