Description

[Technical Field]

[0001] The present invention belongs to the technical field of office cabinets, and specifically relates to a modular movable storage device. [Background technology]

[0002] Although current modular storage devices have fundamental advantages such as flexibility in combination and ease of movement, in actual applications, as exemplified by the published patent document with publication number WO2025007585A1, the inconvenience of user operation in conventional storage boxes has been resolved by designing the storage box with integrated side walls and bottom walls, and drawer sliding and locking mechanisms. However, the following significant drawbacks still remain. First, the inter-module connection mechanisms of existing products generally use a multi-component assembly method, which results in complicated connection operations with small tolerances and significantly degraded user experience. Second, there is a significant problem of the storage unit's functions being monolithic, and the conventional drawer structure lacks a space adjustment mechanism, making it impossible to meet the needs for classifying and storing items.

[0003] Especially when it comes to managing documents of various sizes or small items, users are forced to purchase additional compartments, resulting in a double whammy of reduced space utilization and increased usage costs. This technological bottleneck severely limits the adaptability of modular storage products to different installation environments and the market penetration rate. Summary of the Invention

In the following drawings, the same reference numerals indicate the same characteristics, and therefore, if a characteristic is defined in one drawing, it does not need to be further described in the following drawings.

[0018] 1 to 6, the present invention includes a support base 1 and at least one modular connection unit 2, the support base 1 being capable of mounting the modular connection unit 2, or the support base 1 being provided with mounting grooves for mounting the modular connection unit 2, each modular connection unit 2 being attached with a movable storage unit 3, and casters 4 being provided at the bottom of the four corners of the support base 1 to allow the entire unit to be moved freely. Referring to FIG. 2, the modular connection unit 2 comprises a frame body 21, the top of which is provided with a top fitting structure 22 for fitting with another modular connection unit 2, the bottom of which is provided with a bottom opposing portion 23 for fitting with the top fitting structure 22, the outer surface of which is provided with a side fitting portion 24 for connecting at the side, the inner surface of which is provided with an internal positioning portion 25 for ensuring stable fitting between the joined units, and a through hole 26 arranged in the back panel area of the frame body 21 to facilitate air circulation or wiring and to eliminate the airtight effect as necessary. The bottom opposing portion (23) interlocks with the top fitting structure (22) of another modular connection unit (2), allowing for the combination of upper and lower tiers, and the side fitting portions (24) allow for lateral parallel connection, allowing for flexible addition and subtraction of units and rapid movement according to storage needs. The top fitting structure (22) and the bottom opposing portion (23) form a guide rail structure, and the interface of the guide rail structure is dovetail-shaped, providing a modular movable storage device.

[0019] In some embodiments (not shown), the top mating structure 22 and the bottom mating portion 23 of the modular connection unit 2 are provided with position limiting locks to prevent sliding and separation when connected vertically; dividers and labeling systems can be added inside the storage unit 3 to enable document classification and storage; and a magnetic attraction engagement design can be added to the top mating structure 22 and the bottom mating portion 23 to improve mating stability and simplify operation.

[0020] 4 and 5, a guide groove 33 is provided on the side of the storage box 31, and the dimensions of the guide groove 33 are precisely fitted with the sliding block 35. A rectangular opening 34 is opened in the side wall, which allows the operating state of the internal mechanism to be visually confirmed and allows direct access to the sliding mechanism during cleaning and maintenance. The sliding block 35 slides smoothly along the groove wall within the guide groove 33, and one end of the guide groove 33 is firmly fixed to a screw 36. The screw 36 is threadedly engaged with an adjustment button 37, which realizes accurate driving of the sliding block 35 through fine rotational adjustment. This allows a position limiting block 38 to slide within an adjustment control chamber 314, which is composed of an upper partition plate 39 and a lower partition plate 312. The width of the position limiting block 38 is adjusted by the width of the adjustment control chamber 314. The upper and lower partition plates 39 and 312 are fitted with locking holes 310 that fit the dimensions of the locking blocks 313 at the joints thereof, and the two partition plates are tightly fixed together by the locking engagement, ensuring that the partition plates are always stable and reliable even when loaded or moved. The upper and lower partition plates 39 and 312 are each fitted with two arch grooves 311 at their tops, and these arch grooves 311 allow the interior of the storage box 31 to be flexibly divided into multiple independent storage compartments, allowing for the separate storage of items of different sizes, while also providing internal ventilation and a non-slip design, providing users with a multi-functional storage solution that is highly adjustable, stable, and easy to operate.

[0021] In some embodiments (not shown), the connection point between the sliding block 35 and the screw 36 is changed to a quick-release pin structure, allowing the user to quickly adjust the height of the partition without rotating the adjustment button 37; or a transparent observation window is provided on the top or side of the storage box 31, making it easy to check the storage status of items in each compartment in real time; and by adding an interchangeable vibration-damping spacer between the upper partition 39 and the lower partition 312, the impact of external vibrations on the stored items can be effectively reduced.

[0022]

[0023] Working principle of the present invention: The modular movable storage device uses modular connecting units 2 to achieve free height expansion, and the interlocking structure between the bottom opposing parts 23 and the top fitting structures 22 simplifies the assembly process, allowing for large-scale deployment while significantly reducing manufacturing costs. The user simply inserts the opposing parts 23 into the top fitting structures 22 to complete stacking of units, making operation extremely simple. At the same time, removable upper and lower partition plates 39 and 312 are arranged within the storage unit 3, and an adjustable partition system is formed by inserting and matching the latching holes 310 and locking blocks 313. This not only allows for partitioning of storage areas for multiple types of items, but also allows the partition plates to be removed to recover the entire space, significantly improving the functional adaptability of the device.

[0023] As can be seen from the above description, the above embodiment of the present invention achieves the technical effects of the modular movable storage device using modular connecting units to achieve free height expansion, and the interlocking structure between the bottom opposing parts and the top mating structure simplifies the assembly process, allowing for large-scale deployment while significantly reducing manufacturing costs, and users only need to insert the opposing parts into the mating structures to complete stacking of units, making operation extremely convenient. At the same time, the storage unit is equipped with removable upper and lower partitions, which form an adjustable partition system by inserting and matching the locking holes and locking blocks, allowing not only to partition storage areas for multiple types of items, but also to remove the partitions to recover the entire space, significantly improving the functional adaptability of the device.

[0024] In describing the present invention, directional terms or positional relationships such as "front, back, top, bottom, left, right," "lateral, longitudinal, vertical, horizontal," and "top, bottom" are generally based on the directional terms or positional relationships shown in the drawings and are merely for the convenience and simplification of the description of the present invention. Unless otherwise stated, these directional terms do not indicate or teach that the devices or elements they refer to have a specific orientation or must be constructed and operated in a specific orientation, and are not intended to limit the scope of the present invention. The directional terms "inside, outside" refer to the inside and outside of the outline of each part itself.

[0025] For convenience of explanation, spatially relative terms, such as "above," "above," "on top of," and "above," are used herein to describe the spatial relationship of one device or feature to another device or feature, as illustrated in the figures. Note that spatially relative terms are intended to encompass different orientations of use or operation of the device other than the orientation depicted in the figures. For example, if a device in the figures is inverted, it may be described as "above other devices or structures" or "on other devices or structures," and then later repositioned as "below other devices or structures" or "under other devices or structures." Thus, the exemplary term "above" may encompass both orientations: "above" and "below." The device may be positioned in other different ways (rotated 90 degrees or at other orientations), and the spatially relative descriptions used herein should be interpreted accordingly.

[0026] Furthermore, the use of terms such as "first" and "second" to define parts is merely for the purpose of making it easier to distinguish corresponding parts, and unless otherwise specified, the above terms have no special meaning and should not be understood as limiting the scope of the present invention.

[0027] The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention. Those skilled in the art can make various modifications and changes to the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should fall within the scope of the present invention.
