Description

Technical Field

[0001] This utility model relates to the field of material box technology, specifically a stackable material box. Background Technology

[0002] Stackable material boxes are containers that can be stably stacked one on top of the other, facilitating the classification, storage, and handling of materials. They are characterized by their compact structure, strong load-bearing capacity, convenient access, diverse specifications, and good adaptability. They are commonly used in warehousing, production, and logistics scenarios. Labels, dust covers, and other accessories can be added as needed to improve efficiency and functionality.

[0003] Existing stackable material boxes generally achieve stacking and fixation by setting interlocking slots and protrusions at the top and bottom of the boxes. Although this structure can provide stable positioning in a static state and prevent the material boxes from shifting or tipping over during stacking, it has obvious inconveniences in actual handling. Because the slots and protrusions are interlocked, when it is necessary to move the upper material box, it must first be lifted up a certain distance to detach it from the lower material box before it can be moved horizontally or transported. It cannot be directly removed or moved by horizontal sliding. This handling method increases the labor intensity of the operator and reduces the work efficiency, especially in scenarios where it is necessary to frequently pick up, put down or move material boxes. From the perspective of operating principle, while the interlocking structure provides vertical stability, it also restricts the flexible movement in the horizontal direction, resulting in mechanical interference between material boxes and making it difficult to achieve quick picking and putting down without lifting. Therefore, there is still significant room for improvement in terms of convenient handling of existing structures.

[0004] In view of this, we propose a stackable material box. Utility Model Content

[0005] The purpose of this utility model is to provide a stackable material box, which solves the problem that the existing stackable material boxes are fixed by the slot and the protrusion, which is stable but requires lifting before moving and cannot be directly slid to pick up and put down, making operation inconvenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A stackable material box includes a box body with a lid on top. A stacking mechanism is provided on the box body and the lid. The stacking mechanism includes a positioning groove on the top of the lid. A protective shell is slidably connected to the outer wall of the box body. A spring is provided on the inner wall of the box body, one end of which is fixedly connected to the inner wall of the box body, and the other end of which is fixedly connected to a connecting plate. A positioning block is fixedly connected to the bottom of the connecting plate, and connecting strips are fixedly connected to both sides of the connecting plate. The side of the connecting strip away from the connecting plate is fixedly connected to the inner wall of the protective shell. A positioning mechanism is provided on the protective shell for positioning the protective shell.

[0008] Preferably, a movable buckle is provided between the box body and the lid to enable a detachable connection between the lid and the box body.

[0009] Preferably, the protective shell is provided with a handle, the positioning block is slidably connected to the inner wall of the box, and the outer wall of the connecting plate is slidably connected to the inner wall of the box.

[0010] Preferably, the positioning block is provided with an arc-shaped chamfer, and the positioning grooves are distributed in multiple ways on the cover.

[0011] Preferably, a guide groove structure is provided between the protective shell and the box body, and a dustproof sealing ring is provided on the cover.

[0012] Preferably, the positioning mechanism includes a second spring, one end of which is fixedly connected to the outer wall of the protective shell, and the other end of which is fixedly connected to a disc block. A cylindrical component is fixedly connected to the outer wall of the disc block, and the outer wall of the cylindrical component is slidably connected to the inner wall of the box. A limit groove is formed on the outer wall of the box.

[0013] Preferably, the bottom of the box body is provided with ball bearings, and the cylindrical part is provided with chamfers.

[0014] By employing the above technical solution, this utility model provides a stackable material box. It possesses at least the following beneficial effects:

[0015] 1. This utility model features a stacking mechanism. When stacking is required, the positioning block on the top box aligns with the positioning groove on the bottom box, stabilizing the stack. When handling, simply lift the protective shell upwards. The protective shell, via the connecting strip, moves the connecting plate upwards, compressing the spring. This causes the positioning block to retract into the inner wall of the box, disengaging from the positioning groove and allowing the two boxes to slide relative to each other. This ensures stable and secure stacking, preventing slippage or tipping. During handling, simply lifting the protective shell releases the positioning mechanism, quickly releasing the stack and allowing free sliding between the two boxes. This significantly improves handling efficiency and ease of operation, making it particularly suitable for material management and warehousing scenarios requiring frequent stacking and disassembly.

[0016] 2. This utility model incorporates a positioning mechanism. When the protective shell is lifted upwards by hand, it causes the cylindrical component to move upwards until the cylindrical component engages with the limiting groove under the action of spring two, thus positioning the protective shell. This eliminates the need for users to continuously hold the protective shell up by hand when moving the box, improving the convenience and stability of the operation process, preventing the protective shell from falling back and causing structural reset, and further ensuring the smoothness and safety of the sliding and transporting process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a stackable material box, including a box body 1, a lid 2 on the top of the box body 1, and a stacking mechanism 3 on the box body 1 and the lid 2. The stacking mechanism 3 includes: a positioning groove 31, which is formed on the top of the lid 2; a protective shell 32 slidably connected to the outer wall of the box body 1; a spring 33 on the inner wall of the box body 1, one end of which is fixedly connected to the inner wall of the box body 1, and the other end of which is fixedly connected to a connecting plate 34; a positioning block 36 is fixedly connected to the bottom of the connecting plate 34; and two other components are fixedly connected to the connecting plate 34. The connecting strip 35 is fixedly connected to the inner wall of the protective shell 32 on the side away from the connecting plate 34. When stacking is required, the positioning block 36 on the top box 1 aligns with the positioning groove 31 on the bottom box 1, which stabilizes the stacking of the boxes 1. When moving the boxes, simply lift the protective shell 32 upwards. The protective shell 32 moves the connecting plate 34 upwards via the connecting strip 35. The connecting plate 34 compresses the spring 33, causing the positioning block 36 to retract into the inner wall of the box 1. At this point, the positioning block 36 disengages from the positioning groove 31, allowing the upper and lower boxes 1 to move freely. The design allows for mutual sliding, ensuring stable and secure positioning during stacking, preventing slippage or tipping. During transport, simply lifting the protective shell 32 releases the positioning structure and quickly releases the stacked state, enabling free sliding between the two boxes 1. This significantly improves handling efficiency and ease of operation, making it particularly suitable for material management and warehousing scenarios requiring frequent stacking and splitting. The protective shell 32 is equipped with a positioning mechanism 4 for positioning the protective shell 32. A movable latch is provided between the box 1 and the lid 2 for a detachable connection, facilitating opening and closing operations. Meanwhile, to ensure that the cover 2 is not easily loosened or detached during stacking or handling, the protective shell 32 is provided with a handle, the positioning block 36 is slidably connected to the inner wall of the box body 1, the outer wall of the connecting plate 34 is slidably connected to the inner wall of the box body 1, the positioning block 36 is provided with an arc-shaped chamfer to facilitate docking with the positioning groove 31, the positioning groove 31 is distributed on the cover 2 in multiple ways to improve stability, the protective shell 32 and the box body 1 are provided with a guide slide structure to restrict the protective shell 32 to move only in the vertical direction of the box body 1 to avoid tilting interference, the cover 2 is provided with a dustproof sealing ring to prevent external dust from entering the interior of the box body 1.

[0026] The positioning mechanism 4 includes a second spring 41. One end of the second spring 41 is fixedly connected to the outer wall of the protective shell 32, and the other end of the second spring 41 is fixedly connected to a disc block 42. A cylindrical member 43 is fixedly connected to the outer wall of the disc block 42. The outer wall of the cylindrical member 43 is slidably connected to the inner wall of the box body 1. A limiting groove 44 is provided on the outer wall of the box body 1. When the protective shell 32 is lifted upward by hand, the protective shell 32 drives the cylindrical member 43 to move upward until the cylindrical member 43 is engaged with the limiting groove 44 under the action of the second spring 41, so that the protective shell 32 is positioned. This eliminates the need for the user to continuously hold the protective shell 32 in a lifted state when moving the box body 1, improving the convenience and stability of the operation process, preventing the protective shell 32 from falling back and causing structural reset, and further ensuring the smoothness and safety of the sliding and transporting process. A ball bearing 45 is provided at the bottom of the box body 1 to facilitate the sliding of the box body 1. A chamfer is provided on the cylindrical member 43 to facilitate docking with the limiting groove 44.

[0027] This utility model discloses a stackable material box. When stacking is required, the positioning block 36 on the top box 1 aligns with the positioning groove 31 on the bottom box 1, which stabilizes the stacked boxes 1. When handling, simply lift the protective shell 32 upwards. The protective shell 32 drives the connecting plate 34 upwards via the connecting strip 35. The connecting plate 34 compresses the spring 33. At this time, the connecting plate 34 drives the positioning block 36 to retract into the inner wall of the box 1. The positioning block 36 then disengages from the positioning groove 31, allowing the upper and lower boxes 1 to slide relative to each other. This ensures stable and secure positioning during stacking, preventing slippage or tipping. During handling, simply lift the protective shell 32 to release the positioning structure and quickly release the stacked state, thus enabling free sliding between the two boxes 1. This significantly improves handling efficiency and ease of operation, making it particularly suitable for material management and warehousing scenarios that require frequent stacking and splitting.

[0028] When the protective shell 32 is lifted upwards by hand, the protective shell 32 drives the cylindrical part 43 to move upwards until the cylindrical part 43 is engaged with the limiting groove 44 under the action of the second spring 41, so that the protective shell 32 is positioned. This eliminates the need for the user to continuously hold the protective shell 32 up by hand when moving the box 1, improving the convenience and stability of the operation process, preventing the protective shell 32 from falling back and causing the structure to reset, and further ensuring the smoothness and safety of the sliding and transporting process.
