Description

Technical Field

[0001] This invention relates to the field of furniture technology, and more specifically, to a storage cabinet. Background Technology

[0002] In individual training rooms, storage cabinets become essential when there is a need to systematically store a wide variety of teaching aids (such as cards, building blocks, picture books, and small teaching instruments) while flexibly dividing the space into independent teaching areas. Existing storage cabinets are typically designed with a nine-square grid layout, which allows for the categorization and organization of teaching aids of different types and sizes. This provides each type of item with its own dedicated space, facilitating quick access and organization for teachers and avoiding the time-consuming problem of searching for miscellaneous teaching aids. When used as partitions, the cabinets themselves can divide the space of the individual training room into relatively independent teaching units through the open or semi-open structure of the nine-square grid, without obstructing visual communication. This balances the functionality and interactivity of space division, effectively improving the efficiency and sense of order in the individual training room.

[0003] The uniform nine fixed partition design, while convenient for basic classification, is inconvenient for storing diverse teaching aids in actual use. When faced with teaching aids of varying sizes in individual training rooms, large teaching aids (such as solid geometric models and children's cognitive teaching aid boxes) need to be split or squeezed into a single partition due to insufficient space, resulting in deformation or inconvenience in retrieval. Items of different heights (such as thick teaching picture books and short arithmetic blocks) will cause a waste of vertical space in partitions with fixed heights. It is also inconvenient to dynamically adjust the spatial layout according to the size of the teaching aids.

[0004] Therefore, we propose a storage cabinet. Summary of the Invention

[0005] This invention provides a storage cabinet that, through the installation of a slidably connected partition assembly consisting of a thick rod, a medium rod, and a thin rod inside the cabinet, with quick-hanging components at the ends of the thin rods and locking components inside, allows the partition assembly to form different layered states within the cabinet, enabling flexible adjustment of the internal space layout. This solves the problems mentioned in the background art, namely:

[0006] The existing storage cabinets with nine fixed compartments are not convenient for storing diverse teaching aids. When faced with teaching aids of different sizes, there are problems such as insufficient space, wasted space, and difficulty in dynamically adjusting the space layout according to the size of the teaching aids.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A storage cabinet includes a cabinet body, characterized in that: the cabinet body is provided with multiple partition components, the partition components are used to form different layer states of the cabinet body, the partition components are provided with locking components inside, and the ends of the partition components are provided with quick-hanging components;

[0009] The partition assembly consists of multiple telescopic rods, allowing for adjustment of different partition assembly lengths. A locking component between two connected partition assemblies is connected to a quick-release component to fix the position of the partition assembly.

[0010] The partition assembly includes thick rods, multiple thick rods are evenly distributed inside the cabinet, a middle rod is slidably connected inside the thick rod, a thin rod is slidably connected inside the middle rod, a locking assembly is movably connected inside the thin rod, and quick-hanging assemblies are provided at the ends of the thin rods near the right side and bottom.

[0011] In the above technical solution, a slider is fixedly connected to one end of the thin rod and the middle rod near the dead corner, and the slider is slidably connected inside the groove of the inner wall of the middle rod and the thick rod.

[0012] Preferably, both the middle rod and the thick rod are hollow structures, and the distance between the two middle rods is greater than the distance between the two thin rods.

[0013] Preferably, the outer wall of the thick rod is provided with grooves near the right side and top, and the outer wall of the thick rod is provided with protrusions near the left side and bottom, with one of the protrusions of the thick rod being movably engaged in the groove of the other thick rod.

[0014] Based on this, the locking component includes a ball bearing that is slidably connected inside a thin rod. A chain is fixedly connected to the outer wall of the ball bearing, and a safety buckle is attached to the other end of the chain. The safety buckle is movably connected to the outer wall of the quick-release component.

[0015] Preferably, the quick-release assembly includes a rotating bead, which is movably connected inside the thin rod. A hanging ring is fixedly connected to the outer wall of the thin rod where the rotating bead exits, and a safety buckle is movably connected to the outer wall of the hanging ring.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In a storage cabinet, a nested sliding connection structure of thick, medium, and thin rods, combined with quick-hanging components at the ends of the thin rods and internal locking components, enables flexible adjustment of the cabinet's internal space layering. The thick, medium, and thin rods can slide and extend along their respective inner walls, allowing users to dynamically adjust the height, width, and combination of the shelves (such as merging or splitting sections) according to the size of the teaching aids. The safety buckle of the locking component is movably connected to the hanging ring of the quick-hanging component, quickly fixing the shelf position. This solves the problems of insufficient capacity for large teaching aids, poor adaptability to irregularly shaped teaching aids, and wasted vertical space for items of different heights in traditional fixed nine-grid partitions, significantly improving the storage flexibility and space utilization of diverse teaching aids.

[0018] 2. In a storage cabinet, the sliding mechanism at the ends of the thin and middle rods, along with the grooves on the inner walls of the thick and middle rods, ensures the stability and smoothness of the sliding process of the partition components. This prevents the rods from shifting or jamming during sliding, allowing teachers to easily and accurately adjust the partition layout. Simultaneously, the hollow structure of the thick and middle rods provides a stable sliding track for the sliders while reducing the cabinet's weight, balancing ease of operation and structural reliability. Furthermore, the protrusion and groove interlocking structure on the outer wall of the thick rods enables rapid assembly and positioning of adjacent thick rods, enhancing the overall structural strength of the cabinet and preventing deformation caused by frequent partition adjustments. It also allows for modular expansion of the partition components (such as adding thick rods horizontally or vertically), enabling the storage cabinet to flexibly expand its storage space according to the actual needs of individual training rooms, further optimizing the adaptability of the spatial layout and the durability of the cabinet.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0029] The current design of the storage cabinets with nine uniform fixed compartments is inconvenient for storing diverse teaching aids. When dealing with teaching aids of varying sizes, there are issues of insufficient space, wasted space, and difficulty in dynamically adjusting the space layout according to the size of the teaching aids. Please refer to [link / reference needed]. Figures 1-5 The cabinet shown includes a cabinet body 1, and multiple partition components 11 are provided inside the cabinet body 1. The partition components 11 are used to form different layer states of the cabinet body 1. The partition components 11 are provided with locking components 12 inside, and quick-hanging components 13 are provided at the ends of the partition components 11.

[0030] The partition assembly 11 is composed of multiple telescopic rods, and the length of different partition assemblies 11 can be adjusted. The locking assembly 12 between two connected partition assemblies 11 is connected to the quick-release assembly 13 and is used to fix the position of the partition assembly 11.

[0031] The partition assembly 11 includes a thick rod 110, with multiple thick rods 110 evenly distributed inside the cabinet 1. A middle rod 111 is slidably connected inside the thick rod 110, and a thin rod 112 is slidably connected inside the middle rod 111. A locking assembly 12 is movably connected inside the thin rod 112, and quick-release assemblies 13 are provided at the ends of the thin rod 112 near the right side and the bottom.

[0032] For implementation, see Figure 7 As shown, a slider 14 is fixedly connected to one end of the thin rod 112 and the middle rod 111 near the dead corner. The slider 14 is slidably connected inside the groove on the inner wall of the middle rod 111 and the thick rod 110.

[0033] When it is necessary to adjust the layering state of the partition assembly 11, the slider 14 can slide freely in the groove along a preset direction, such as horizontal or vertical, thereby driving the thin rod 112 to extend or move in position inside the middle rod 111 and the middle rod 111 inside the thick rod 110; the geometry of the groove, such as width and depth, is strictly matched with the shape of the slider 14 to form a limiting constraint, ensuring that the rod can only slide in a single direction, avoiding deviation, tilting or detachment during movement, and ensuring the stability and accuracy of the partition assembly 11 during adjustment;

[0034] Furthermore, the thin rod 112 slides within the groove of the middle rod 111 via the slider 14, enabling the thin rod 112 to extend or retract relative to the middle rod 111; the middle rod 111, in turn, slides within the groove of the thick rod 110 via another set of sliders 14, enabling the middle rod 111 to extend or retract relative to the thick rod 110. This three-level nested sliding structure of "thin rod 112-middle rod 111-thick rod 110" allows the partition assembly 11 to form a multi-dimensional adjustable layered space within the cabinet 1—for example, by sliding the thin rod 112, the lateral spacing between adjacent thin rods 112 can be adjusted to match the width of the teaching aids, and by sliding the middle rod 111, the longitudinal height of the partition can be adjusted to match the height of the teaching aids; the cooperation between the slider 14 and the groove provides a smooth mechanical transmission path for this process, avoiding operational jamming caused by excessive friction, while the limiting effect ensures that each rod remains coaxially aligned after sliding, maintaining the regularity of the internal structure of the cabinet 1;

[0035] Secondly, once the partition assembly 11 is adjusted to the target position, the contact interface between the slider 14 and the slide groove can distribute the weight of the teaching aid borne by the thin rod 112 and the middle rod 111, avoiding deformation of the rod due to single-point force. For example, when a heavy object is placed on the thin rod 112, the weight is transferred to the inner wall of the slide groove of the middle rod 111 through the slider 14, and then further transferred to the slide groove of the thick rod 110 through the slider 14 of the middle rod 111, and finally evenly borne by the frame structure of the cabinet 1. This layered load transfer mechanism, combined with the lateral constraint of the slide groove on the slider 14, effectively enhances the structural rigidity of the partition assembly 11 under load, avoids shaking or damage caused by frequent adjustments or the placement of heavy objects, and ensures that the cabinet is both flexibly adjustable and reliably durable.

[0036] Depend on Figure 4 and Figure 7 As can be seen from the text, both the middle rod 111 and the thick rod 110 are hollow structures, and the distance between the two middle rods 111 is greater than the distance between the two thin rods 112.

[0037] The core function of the hollow design is to provide movement space for the internally nested sliding components such as the thin rod 112 and the middle rod 111, while reducing the weight of the cabinet 1. The hollow cavity of the thick rod 110 can accommodate the sliding of the middle rod 111 and its end slider 14, while the hollow cavity of the middle rod 111 provides a sliding track for the thin rod 112 and its slider 14. This "rod-within-a-rod" structural design allows the thin rod 112 to extend and retract within the middle rod 111, and the middle rod 111 to extend and retract within the thick rod 110, thereby achieving multi-dimensional adjustment of the partition assembly 11 in terms of longitudinal height and transverse width. Furthermore, the hollow structure reduces material usage while maintaining the strength of the rods, lowering the overall weight of the cabinet 1. This facilitates handling and layout adjustments, reduces the load-bearing pressure on the frame of the cabinet 1, and improves long-term durability.

[0038] Furthermore, the spacing between the two middle rods 111 and the spacing between the two thin rods 112 ensure that the rods at each level do not interfere with each other and work together when they extend or retract. For example, when it is necessary to store wide teaching aids, the lateral spacing can be increased by sliding the middle rods 111, while the sliding of the thin rods 112 within the middle rods 111 can further subdivide or merge local spaces, forming a dual adjustment mode of "coarse adjustment + fine adjustment". In the longitudinal height adjustment, the hollow structure of the middle rods 111 and the thick rods 110 allows the thin rods 112 and the middle rods 111 to slide in the vertical direction, while the spacing difference design ensures the installation stability of the shelves when they are installed on the thin rods 112 at different heights. For example, the height of tall teaching aids can be increased by raising the middle rods 111, while the height of short teaching aids can be compressed by lowering the middle rods 111. Moreover, the sliding of the thin rods 112 within the middle rods 111 can further divide the same middle rod 111 interval into multiple low-level layers, avoiding waste of longitudinal space.

[0039] See Figure 5 As shown, the outer wall of the thick rod 110 has grooves near the right side and top, and protrusions near the left side and bottom. The protrusion of one thick rod 110 is movably engaged in the groove of another thick rod 110, forming a standardized interface of "left protrusion and right concave, bottom protrusion and top concave".

[0040] When it is necessary to connect adjacent thick rods 110, such as horizontal splicing or vertical stacking, the protrusion of one thick rod 110 is aligned with the groove of another thick rod 110. By sliding or pressing, the protrusion is embedded into the groove. The geometric fit allows for tool-free quick assembly. This design eliminates the cumbersome steps of traditional screw fixing. Teachers can flexibly adjust the number and arrangement of thick rods 110 on-site according to the space requirements of the training room or the storage habits of teaching aids. For example, they can increase the width of horizontal thick rods 110 or increase the height of vertical thick rods 110, so that the cabinet 1 can be transformed from a fixed nine-square grid structure into a modular system that can be freely combined.

[0041] When cabinet 1 bears the weight of teaching aids or external impacts, the load is evenly distributed to adjacent thick rods 110 through the contact surface of the protrusions and grooves, avoiding local deformation caused by single-point force. For example, the groove of the top thick rod 110 supports the protrusion of the upper thick rod 110, transferring the vertical weight to the lower structure. The convex and concave interlocking of adjacent thick rods 110 in the lateral direction enhances the lateral rigidity of cabinet 1 and reduces lateral swaying caused by frequent adjustment of partitions. This "building block" interlocking structure makes cabinet 1 form a mesh support frame as a whole, which significantly improves the deformation resistance compared to the single board support of traditional fixed partition storage cabinets.

[0042] When fine-tuning of local space is required, the fine partition layers can be adjusted within the fixed thick rod 110 frame by sliding the middle rod 111 and thin rod 112 without disassembling the overall structure. By engaging the left protrusion with the right groove, the number of thick rods 110 can be increased in the width direction of the cabinet 1, expanding the horizontal storage space for storing extra-long teaching aids such as rolled teaching drawings and long strip teaching aid shelves. By engaging the bottom protrusion with the top groove, the number of thick rods 110 layers can be increased in the height direction of the cabinet 1, flexibly adjusting the layer height to reserve sufficient vertical space for tall teaching aids. It is suitable for corner spaces or complex layouts in individual training rooms, solving the problems of fixed shape and low space utilization of traditional cabinets 1.

[0043] Additionally, see Figure 6 and Figure 8 As shown, the locking assembly 12 includes a ball bearing 122, which is slidably connected inside the thin rod 112. A chain 120 is fixedly connected to the outer wall of the ball bearing 122, and a safety buckle 121 is attached to the other end of the chain 120. The safety buckle 121 is movably connected to the outer wall of the quick-release assembly 13.

[0044] The quick-release assembly 13 includes a rotating ball 130, which is movably connected inside the thin rod 112. A hanging ring 131 is fixedly connected to the outer wall of the thin rod 112 where the rotating ball 130 passes through. A safety buckle 121 is movably connected to the outer wall of the hanging ring 131.

[0045] When it is necessary to fix the relative position of adjacent thin rods 112, the user can move or pull the safety buckle 121, causing the safety buckle 121 to pull the chain 120 and the ball bearing 122, so that the ball bearing 122 slides in the inner wall track of the thin rod 112, pulling the chain 120 out of the thin rod 112 and extending the extension length of the safety buckle 121. When the safety buckle 121 moves to the target position with the chain 120, it is fastened to the hanging ring 131 of the quick-hanging assembly 13. The locking structure of the safety buckle 121, such as the spring buckle or the magnetic locking tongue, forms a rigid connection, locking the two thin rods 112 into a whole and preventing them from sliding relative to each other. Conversely, pressing the unlocking part of the safety buckle 121, such as the ball bearing 122 reset button, can make the safety buckle 121 disengage from the hanging ring 131, realizing the quick disassembly of the partition assembly 11 and providing convenience for space adjustment.

[0046] The quick-release assembly 13 has a rotating bead 130 that is movably connected inside the thin rod 112. The hanging ring 131 extending out of the outer wall can rotate freely with the rotating bead 130 by 6°, which solves the limitation problem of traditional rigid connection when docking at multiple angles. When adjacent thin rods 112 are connected at different angles or directions, such as horizontal, vertical or inclined, the hanging ring 131 can adjust its position by rotating the rotating bead 130 to ensure that the safety buckle 121 can be accurately fastened without aligning a specific interface.

[0047] Thin rods 112 at the same horizontal height are connected to hanging rings 131 of adjacent thin rods 112 via safety buckles 121, forming a lateral tensile constraint to prevent the thin rods 112 from shifting horizontally due to the weight of the teaching aids; the upper and lower thin rods 112 are connected to the safety buckles 121 via hanging rings 131 at the bottom and top, respectively, to transfer the vertical load to the cabinet frame 1 layer by layer, avoiding overload of a single thin rod 112; for thin rods 112 near the outer wall of the cabinet 1, their safety buckles 121 are directly fastened to the pre-set hanging rings 131 of the cabinet 1, so that the entire partition assembly 11 and the cabinet 1 form a rigid whole, enhancing the anti-overturning ability;

[0048] By unlocking the safety buckle 121, the thin rod 112 can slide freely within the middle rod 111, and the middle rod 111 can slide freely within the thick rod 110, achieving stepless adjustment of the spatial layout. When it slides to the target position, the ball bearing 122 pulls the safety buckle 121 to engage the hanging ring 131, locking the thin rod 112 with the adjacent rod, transforming the adjustable sliding connection into a stable rigid connection, ensuring the structural safety of the teaching aids when stored. This "sliding adjustment - quick locking" mechanism retains the flexible adjustment advantages of traditional storage cabinets while avoiding safety hazards caused by loose sliding parts through a mechanical locking structure.
