Description

Technical Field

[0001] This utility model relates to the field of storage box technology, and in particular to an acrylic storage box that can be used in combination. Background Technology

[0002] In daily production and life, acrylic storage boxes are widely used for classifying and storing items such as spare parts, stationery, and cosmetics due to their high transparency, aesthetics, and durability. However, most existing acrylic storage boxes are independent, single-unit structures with fixed storage capacities, making it impossible to flexibly adjust them according to the quantity and volume of the items stored. When managing multiple categories of items, it is often necessary to purchase multiple storage boxes of different sizes, which not only leads to low storage space utilization but also makes item management appear disorganized.

[0003] To address the issue of fixed capacity in individual storage boxes, some stackable storage boxes have emerged on the market. However, these products typically rely on simple stacking or snap-fit ​​connections, often resulting in unstable structures. When moved or with frequent opening and closing of the lids, stacked boxes are prone to slipping, tipping over, or even scattering, posing safety hazards. Furthermore, existing combination methods generally lack effective scalability and standardized connections, hindering stable and flexible horizontal and vertical multi-dimensional combinations and limiting their application in large-scale, systematic warehouse management.

[0004] Therefore, there is an urgent need for a storage box solution that is stable in connection, flexible in expansion, and easy to operate, which can be freely combined according to user needs to form a stable and unified whole to meet dynamically changing storage requirements. Utility Model Content

[0005] In order to overcome the shortcomings of traditional single storage boxes with fixed capacity, and the unstable connection structure and poor expandability of existing combined storage boxes, this utility model provides a combinable acrylic storage box.

[0006] Technical Solution: A combinable acrylic storage box includes a storage box, locking rods, a locking cylinder, a cover, an observation plate, a mounting base, and a ring handle. The storage boxes are open at the front and hollow inside. Four storage boxes are arranged in a stacked configuration of two on each side. The edges of the storage boxes are machined into rounded transition edges, and each rounded edge is connected to a locking rod. The locking cylinder is a cylindrical structure with slots on its left, right, top, and bottom sides. The slots are shaped to fit the locking rods and slide in contact with them. When the four storage boxes are stacked, the edges of adjacent storage boxes form connecting nodes, where four or two locking rods converge. The locking cylinder slides between the locking rods. A cover is snapped into the front opening of the storage box, and an observation plate is connected to the center of the cover. A mounting base is installed on the center of the front side of the observation plate, and a ring handle is rotatably connected to the mounting base.

[0007] In one embodiment, the device further includes a stop block, a protrusion, and a screw. A threaded hole is provided at the center of the front end of the locking cylinder. The stop block is a circular flat plate structure with a diameter larger than the outer diameter of the locking cylinder. A screw is connected to the rear side wall of the stop block. The external thread of the screw forms a threaded connection with the threaded hole of the locking cylinder. Multiple protrusions are connected to the front side wall of the stop block.

[0008] In one embodiment, a marking slot is also included, which is connected to the lower side of the front sidewall of the cover for storing label strips.

[0009] In one embodiment, an annular sealing strip is fitted into the inner edge of the lid, and the sealing strip is interference-fitted with the inner wall of the opening of the storage box.

[0010] In one embodiment, both the storage box and the observation plate are made of high-transmittance acrylic material, and the inner wall of the storage box is provided with a polished layer.

[0011] In one embodiment, the screw and the threaded hole of the locking cylinder are fitted with fine-pitch threads.

[0012] The present invention has the following advantages: 1. Through the sliding fit structure of the locking rod and the locking cylinder, multiple storage boxes can be flexibly combined and firmly connected in the horizontal and vertical directions. This design uses the locking cylinder to simultaneously constrain the locking rods of adjacent storage boxes, transforming point connection into surface contact, which significantly enhances the overall rigidity and stability of the assembly, enabling it to adapt to storage needs of different scales.

[0013] 2. The lid's embedded snap-fit ​​design, combined with the ring handle, allows for easy pulling out or pushing back of the lid, making operation effortless. The stop block, through the screw and locking cylinder, can limit the position of the storage box and the locking cylinder, preventing the storage box from sliding due to inertia when opening and closing the lid. At the same time, the groove at the top corner of the lid is adapted to the stop block, without affecting opening and closing, thus balancing convenience and stability.

[0014] 3. The observation board allows direct viewing of the items inside the storage boxes without frequent opening of the lid, reducing operational steps; the marking slot can insert classification labels, allowing for quick identification of the corresponding storage boxes according to the stored content, avoiding the hassle of searching one by one, improving the efficiency of item management, and is especially suitable for the orderly management of multiple stacked items.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] Example: A combinable acrylic storage box, such as Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the system includes a storage box 1, a locking rod 2, a locking cylinder 3, a cover 5, an observation plate 51, a marking groove plate 53, a mounting base 6, and a ring handle 61. The storage box 1 is a hollow component with an open front side. There are four of them, arranged in a stacked arrangement of two on top and two on the bottom. The edges of the storage box 1 (specifically, the narrow edges formed by the intersection of the top surface and the two side surfaces, and the narrow edges formed by the intersection of the bottom surface and the two side surfaces) are all machined into rounded transition edges. A locking rod 2 is fixedly connected to each rounded edge. The locking rod 2 is coaxial with the rounded edge of the storage box 1 and extends to the same length. The locking cylinder 3 is a cylindrical structure with slots 31 on the left and right sides and the top and bottom sides inside. The cross-sectional shape and size of the slots 31 are the same as those of the locking rods 2. The type is adapted and forms a sliding fit with the locking rod 2. When the four storage boxes 1 are stacked according to the principle of left-right symmetry and top-bottom alignment, the edges of adjacent storage boxes 1 form connection nodes (including the central connection point, left edge connection point, right edge connection point, upper edge connection point, and lower edge connection point). At each connection node, four locking rods 2 or two locking rods 2 converge. The locking cylinder 3 can slide and fit between the locking rods 2 along the axis of the locking rods 2, and the outer wall of the locking cylinder 3 is tightly fitted with the arc edge of the storage box 1 to lock the combined state of the storage boxes 1. According to the above-mentioned cooperation method between the locking cylinder 3 and the locking rod 2, multiple sets of storage boxes 1 can be stacked infinitely. The front opening of the storage box 1 is embedded with a cover. The lid 5 and the inner wall of the opening of the storage box 1 are fitted with a clearance fit. An annular sealing strip is embedded on the inner edge of the lid 5. When the lid 5 is closed, this sealing strip is press-fitted with the inner wall of the opening of the storage box 1, enhancing the sealing performance of the storage box 1 when closed and effectively preventing moisture and dust from entering. An observation board 51 is fixedly connected to the middle of the lid 5, allowing operators to visually observe the contents of the storage box 1. Both the storage box 1 and the observation board 51 are made of high-transmittance acrylic material, and the inner wall of the storage box 1 has a polished layer. The high-transmittance material further improves the visibility of the observation board 51, and the polished inner wall reduces scratch damage during storage. A marking slot plate 53 is fixedly connected to the front side wall of the observation plate 51 below the observation plate 51. The marking slot plate 53 is a transparent hollow structure with an open top. The internal cavity size of the marking slot plate 53 is adapted to the placement of the label strip. The operator can fill in the label strip according to the classification information of the items in the storage box 1 and insert the label strip into the cavity of the marking slot plate 53 to realize the rapid identification and classification management of different storage boxes 1. A mounting base 6 is fixedly installed in the middle of the front side of the observation plate 51. A ring handle 61 is rotatably connected to the mounting base 6. The ring handle 61 can rotate around the mounting base 6 to provide a force point for opening and closing the cover 5, making it easy for the operator to pull the ring handle 61 to pull the cover 5 forward along the opening of the storage box 1.

[0026] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, it also includes a stop block 4, a protrusion 41, and a screw 42. A threaded hole 43 is provided at the center of the front end of the locking cylinder 3. The stop block 4 is a circular flat plate structure with a diameter larger than the outer diameter of the locking cylinder 3. A screw 42 is fixedly connected to the center of the rear side wall of the stop block 4. The external thread of the screw 42 is adapted to the threaded hole 43 of the locking cylinder 3. The stop block 4 can be detachably installed at the front end of the locking cylinder 3 through the threaded engagement of the screw 42 and the threaded hole 43. A groove is provided at each of the four top corners of the cover 5. The arc shape of the groove fits the outer wall shape of the stop block 4, ensuring that the stop block 4 does not interfere with the normal opening and closing of the cover 5. The screw 42 and the threaded hole 43 of the locking cylinder 3 are engaged with fine threads. The fine thread engagement can improve the tightness of the connection between the screw 42 and the locking cylinder 3 and reduce the risk of loosening. Four opposing protrusions 41 are fixedly connected to the center of the front side wall of the stop block 4, providing a force application point for the operator to rotate the stop block 4, which facilitates the installation and removal of the stop block 4.

[0027] When assembling four storage boxes 1, stack them according to the principle of left-right symmetry and top-bottom alignment, so that the arc edges of adjacent storage boxes 1 meet, forming a central connection point and left, right, top, and bottom edge connection points. Then, take the locking cylinder 3 and align the inner groove 31 of the locking cylinder 3 with the locking rod 2 at each connection point. Push the locking cylinder 3 backward along the axis of the locking rod 2 until the outer wall of the locking cylinder 3 is completely in contact with the arc edge of the storage box 1. At this time, the locking cylinder 3 achieves combination locking of the four storage boxes 1 through the sliding cooperation of the groove 31 and the locking rod 2. If it is necessary to expand the stacking, repeat the above operation and install the locking cylinder 3 at the connection node of the newly added storage box 1 group. To prevent the storage box 1 from sliding due to inertia when opening and closing the cover 5, take the stop block 4 and align the screw 42 on its rear side wall with the threaded hole 43 at the front end of the locking cylinder 3. The operator pinches the four protrusions 41 on the front side of the stop block 4 and rotates the stop block 4 clockwise to drive the screw 42 into place. The threaded hole 43 is extended until the rear side wall of the stop block 4 contacts the outer wall of the storage box 1. At this time, the stop block 4, through the threaded engagement of the screw 42 and the locking cylinder 3, restricts the relative displacement between the storage box 1 and the locking cylinder 3, thus completing the limiting and reinforcement. When opening the cover 5, the operator pulls the annular handle 61 on the front side of the observation plate 51 and pulls the cover 5 forward along the front opening of the storage box 1. At this time, the groove at the top corner of the cover 5 slides along the outer wall of the stop block 4 without interference. When closing the cover 5 again, push the cover 5 backward along the inner wall of the opening of the storage box 1 until it is locked in place. If it is necessary to disassemble the storage box 1, first pinch the protrusion 41 on the front side of the stop block 4 and rotate the stop block 4 counterclockwise to drive the screw 42 out of the threaded hole 43 of the locking cylinder 3. Remove the stop block 4, and then pull the locking cylinder 3 forward along the axis of the locking rod 2 to disengage the locking groove 31 from the locking rod 2, thereby releasing the lock on the storage box 1. Finally, the storage box 1 can be disassembled or reassembled as needed.
