Technical Field
[0001] This application relates to the field of storage equipment technology, and more particularly to a storage box. Background Technology
[0002] Storage boxes, as a common storage solution, are widely used in homes, offices, and businesses to organize and store various items. With increasingly limited living space and diverse usage needs, users are placing higher demands on the functionality and space utilization of storage boxes.
[0003] Traditional storage boxes are mostly designed as individual units. When increased storage capacity is needed, multiple boxes are usually placed side by side, which does not make full use of vertical space. Although there are some stackable storage boxes on the market, these use complex locking mechanisms to secure them. These mechanisms are inconvenient to install and require considerable force or tools to disassemble, causing inconvenience for users in daily use. Summary of the Invention

[0083] It should be understood that the dimensions of the components shown in the accompanying drawings are provided for better understanding and easier description, and this application is not limited to the dimensions shown in the drawings. For the sake of clarity, elements unrelated to the description have been omitted from the details of this specification.
[0084] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0085] Some embodiments of this application will now be described with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0086] Please see Figures 1 to 3 Some embodiments of this application provide a storage box 100, which includes at least two assembly units 10. Multiple assembly units 10 are stacked along a first direction X. Each assembly unit 10 includes a box body 11, a first limiting strip 12, and a first mating strip 13 (see...). Figure 5 ) and Activity Lock 14.
[0087] Please see Figures 2 to 4The box body 11 includes a side wall 111 and a bottom wall 112 connected to each other, which together enclose a storage cavity 113 for storing items. The side wall 111 is located on the side of the bottom wall 112 along a first direction X, and the bottom wall 112 has a stop opening 1121 on the side opposite to the side wall 111. The first direction X is usually a vertical direction, that is, the up and down direction when the storage box 100 is in normal use.
[0088] The first limiting strip 12 extends along the second direction Y, which is perpendicular to the first direction X. The first limiting strip 12 is located on the side of the side wall 111 away from the bottom wall 112 along the first direction X, for example, at the top edge of the side wall 111. The first mating strip 13 also extends along the second direction Y and is located on the side of the side wall 111 close to the bottom wall 112 along the first direction X, for example, at the bottom edge of the side wall 111.
[0089] A movable lock 14 is mounted on the side wall 111. The movable lock 14 includes a stop 141, which is configured to move along a first direction X and in a direction opposite to the first direction X. This movable design allows the stop 141 to move between a locked position and an unlocked position.
[0090] When two combination units 10 are stacked along the first direction X, the first mating strip 13 of the upper combination unit 10 is located on one side of the first limiting strip 12 of the lower combination unit 10 along the first direction X and abuts against each other. At the same time, the stop member 141 of the lower combination unit 10 is embedded in the stop opening 1121 of the upper combination unit 10 in the opposite direction of the first direction X (i.e., upward).
[0091] In the above embodiments, the mutual abutment of the first limiting strip 12 and the first mating strip 13 effectively limits the upper and lower combined units 10 in the first direction X and its opposite direction, restricting relative movement in the vertical direction. Furthermore, the cooperation between the stop 141 and the stop opening 1121 achieves limitation in the direction perpendicular to the first direction X, effectively restricting horizontal displacement of the stack. This connection method eliminates the need for complex locking mechanisms. During stacking, simply align the first limiting strip 12 and the first mating strip 13 of two adjacent combined units 10, slide the first mating strip 13 along the second direction Y to below the first limiting strip 12, and allow the stop 141 to engage with the stop opening 1121 to complete the locking. During disassembly, simply remove the stop 141 from the stop opening 1121, and one combined unit 10 can be directly slid along the direction opposite to the second direction Y to separate the two combined units 10. The entire process requires no tools, greatly improving ease of use.
[0092] In some embodiments, please refer to Figure 2 and Figure 5The side wall 111 has a first wall 11a, a second wall 11b, a third wall 11c and a fourth wall 11d connected in sequence. The first wall 11a and the third wall 11c are arranged opposite each other along the third direction Z, and the second wall 11b and the fourth wall 11d are arranged opposite each other along the second direction Y. The first direction X, the second direction Y and the third direction Z are perpendicular to each other.
[0093] In some embodiments, the first wall 11a, the second wall 11b, the third wall 11c, the fourth wall 11d, and the bottom wall 112 enclose a storage cavity 113.
[0094] In some embodiments, the assembly unit 10 further includes a third limiting strip 15, which extends along the second direction Y and is located along the first direction X on the side of the third wall 11c away from the bottom wall 112 (i.e., the top). The first limiting strip 12 is located on the side of the first wall 11a away from the bottom wall 112. Correspondingly, the assembly unit 10 also includes a third mating strip 16, which extends along the second direction Y and is located along the first direction X on the side of the third wall 11c near the bottom wall 112 (i.e., the bottom). The first mating strip 13 is located on the side of the first wall 11a near the bottom wall 112.
[0095] In the above embodiment, when two combination units 10 are stacked, the third mating strip 16 of the upper combination unit 10 is located on one side of the third limiting strip 15 of the lower combination unit 10 along the first direction X and abuts against each other. In this way, limiting is formed on both sides of the combination unit 10, which helps to improve the comprehensiveness of the limiting between the combination units 10, increases the stability of the connection between the combination units 10, and also effectively reduces the shaking between the combination units 10, thereby improving the overall stability of the storage box 100.
[0096] In some embodiments, please refer to Figure 5 and 6 The first limiting strip 12 includes a first segment 121, a second segment 122, and a third segment 123 connected sequentially along the second direction Y. Along the first direction X, the distance between the first segment 121 and the bottom wall 112 is greater than the distance between the third segment 123 and the bottom wall 112, forming a roughly descending stepped profile. The first mating strip 13 abuts against the first segment 121, the second segment 122, and the third segment 123. This multi-segment contact design greatly increases the mating area, resulting in a more uniform pressure distribution and avoiding localized stress concentration. Simultaneously, the stepped structure provides excellent guidance during stacking; even with slight deviations, the inclined surface can guide automatic alignment, reducing stacking difficulty.
[0097] In some embodiments, please refer to Figure 5 and 7The third limiting strip 15 includes a fourth segment 151, a fifth segment 152, and a sixth segment 153 connected sequentially along the second direction Y. Along the first direction X, the distance between the fourth segment 151 and the bottom wall 112 is greater than the distance between the sixth segment 153 and the bottom wall 112, forming a roughly descending stepped profile. The third mating strip 16 abuts against the fourth segment 151, the fifth segment 152, and the sixth segment 153. This multi-segment contact design greatly increases the mating area, resulting in a more uniform pressure distribution and avoiding localized stress concentration. Simultaneously, the stepped structure provides excellent guidance during stacking; even with slight deviations, the inclined surface guides automatic alignment, reducing stacking difficulty.
[0098] In some embodiments, please refer to Figure 5 and 8 The first mating strip 13 includes a first part 131, a second part 132, and a third part 133 connected sequentially along the second direction Y. The first part 131 abuts against the first segment 121, the second part 132 abuts against the second segment 122, and the third part 133 abuts against the third segment 123. Along the first direction X, the thickness of the first part 131 is greater than the thickness of the third part 133. The different thicknesses can adapt to the stress requirements of different segments, providing stronger support at the first segment 121 and facilitating guidance and insertion at the third segment 123.
[0099] In some embodiments, please refer to Figure 3 and 9 The third mating strip 16 includes a fourth part 161, a fifth part 162, and a sixth part 163 connected sequentially along the second direction Y. The fourth part 161 abuts against the fourth segment 151, the fifth part 162 abuts against the fifth segment 152, and the sixth part 163 abuts against the sixth segment 153. Along the first direction X, the thickness of the fourth part 161 is greater than the thickness of the sixth part 163. The different thicknesses can adapt to the stress requirements of different segments, providing stronger support at the first segment 121 and facilitating guidance and insertion at the third segment 123.
[0100] In some embodiments, please refer to Figure 5 To supplement the limiting structures in all directions, the combined unit 10 also includes a second limiting strip 17 and a second mating strip (not shown). The second limiting strip 17 extends along the third direction Z and is located on the side of the side wall 111 away from the bottom wall 112 along the first direction X (i.e., the top). The second mating strip extends along the third direction Z and is located on the side of the side wall 111 close to the bottom wall 112 along the first direction X (i.e., the bottom). The second mating strip of one combined unit 10 is located on the side of the second limiting strip 17 of another combined unit 10 along the first direction X and abuts against it.
[0101] When two assembly units 10 are stacked, the second mating strip of the upper assembly unit 10 is located on one side of the second limiting strip 17 of the lower assembly unit 10 along the first direction X and abuts against each other. In this way, a complete limiting system is formed in the second direction Y and the third direction Z, so that the stack can remain stable in all horizontal directions and effectively resist external impacts and vibrations.
[0102] In some embodiments, please refer to Figure 5 The first mating strip 13 is located outside the receiving cavity 113, and the first limiting strip 12 is located inside the receiving cavity 113. Along the first direction X, the side wall 111 near the bottom wall 112 is provided with a stepped concave surface 11e, and the first mating strip 13 is provided on the stepped concave surface 11e. The stepped concave surface 11e of one assembly unit 10 is spaced apart from the inner surface of the side wall 111 of another assembly unit 10, and the first mating strip 13 of one assembly unit 10 is in contact with the inner surface of the side wall 111 of another assembly unit 10.
[0103] When two assembly units 10 are stacked, the stepped concave surface 11e of the upper assembly unit 10 is spaced apart from the inner surface of the side wall 111 of the lower assembly unit 10, forming an appropriate gap. This gap provides accommodating space for the first limiting strip 12, the third limiting strip 15, the first mating strip 13, and the third mating strip 16. At the same time, the first mating strip 13 of the upper assembly unit 10 contacts the inner surface of the side wall 111 of the lower assembly unit 10, ensuring the compactness and stability of the installation between adjacent assembly units 10.
[0104] In some embodiments, please refer to Figure 10 and Figure 11 The side wall 111 is provided with a mounting cavity 1111 and a first opening 1112 communicating with the mounting cavity 1111. The first opening 1112 communicates with the outside of the box body 11 along the first direction X. The stop member 141 is movably mounted in the mounting cavity 1111. The movable lock 14 also includes an elastic member 142. The elastic member 142 elastically abuts against the box body 11 and the stop member 141. The elastic member 142 is used to drive the stop member 141 to extend out of the first opening 1112 in the opposite direction of the first direction X, so that a part of the stop member 141 can be inserted into the stop opening 1121 when the two combined units 10 are stacked.
[0105] In some embodiments, the movable lock 14 further includes a mounting frame 143, which is engaged in the mounting cavity 1111. Along the first direction X, one end of the mounting frame 143 is provided with a stop wall 1431, and the other end of the mounting frame 143 is provided with an elastic wall 1432. The stop wall 1431 has a second opening 143a along the first direction X, which communicates with the first opening 1112. The elastic wall 1432 is spaced apart from the bottom wall 112. The elastic element 142 and the stop element 141 are installed in the mounting frame 143. One end of the elastic element 142 abuts against the elastic wall 1432, and the other end of the elastic element 142 abuts against the stop element 141. The elastic element 142 is used to drive the part of the stop element 141 to abut against the stop wall 1431. When the part of the stop element 141 abuts against the stop wall 1431, the other part of the stop element 141 extends out of the second opening 143a and the first opening 1112, so that it can enter the stop port 1121 of the upper combination unit 10 to realize the locking function.
[0106] It is understood that in the above embodiment, the elastic wall 1432 and the bottom wall 112 are spaced apart to allow sufficient space for the movement of the elastic member 142. When part of the stop member 141 abuts against the stop wall 1431 and the other part of the stop member 141 extends out of the second opening 143a and the first opening 1112, the movable lock 14 is in the locked state, that is, at this time the stop member 141 can extend into the stop opening 1121. When force is applied to the stop member 141 and the elastic effect of the elastic member 142 is overcome, so that the stop member 141 is retracted into the mounting frame 143, the movable lock 14 is in the unlocked state, and the combined unit can be detached from another combined unit.
[0107] In some embodiments, the mounting cavity 1111 is located within the receiving cavity 113, and the side wall 111 is further provided with a third opening 1113 communicating with the mounting cavity 1111. The third opening 1113 communicates with the outside of the box body 11 along the second direction Y. The stop member 141 is provided with a force-receiving recess 1411, which is exposed in the third opening 1113. The user can press the force-receiving recess 1411 to overcome the elastic force of the elastic member 142, causing the stop member 141 to retract into the mounting cavity 1111, releasing the locked state, and facilitating the separation of the stacked assembly units 10.
[0108] The movable lock 14 in the above embodiment achieves automatic locking during stacking through the automatic drive of the elastic element 142, greatly improving ease of use. Secondly, the design of the stop wall 1431 limits the excessive extension of the stop element 141, ensuring the reliability of the lock. Furthermore, the setting of the force-bearing recess 1411 makes the unlocking operation simple and intuitive; the user only needs to press lightly to complete the disassembly.
[0109] In some embodiments, the end of the stop 141 that extends into the stop opening 1121 has an inclined surface (not shown). When two assembly units 10 need to be stacked, the user simply slides the upper assembly unit 10 along the second direction Y toward the lower assembly unit 10. During this process, the inclined surface of the stop 141 of the lower assembly unit 10 will contact the corresponding part of the upper assembly unit 10. Due to the special geometry of the inclined surface, a component force is generated during the sliding contact, which makes it easier to push the stop 141 into the mounting frame 143.
[0110] In some embodiments, please refer to Figure 4 and Figure 12 The storage box 100 also includes a lid 20, which is installed on the side of at least two assembly units 10 in the opposite direction of the first direction X to seal the storage cavity 113. The lid 20 has a positioning opening 22 on the side facing the assembly unit 10. The lid 20 has a fourth mating strip 21 extending in the second direction Y. The fourth mating strip 21 is located on the side of the lid 20 near the box body 11 in the first direction X. The fourth mating strip 21 is located on the side of the first limiting strip 12 of the adjacent assembly unit 10 in the first direction X and abuts against each other. The stop member 141 of the assembly unit 10 is inserted into the positioning opening 22 in the opposite direction of the first direction X.
[0111] When the lid 20 is closed, the fourth mating strip 21 is located on one side of the first limiting strip 12 of the adjacent assembly unit 10 along the first direction X and abuts against each other. At the same time, the stop 141 of the assembly unit 10 is inserted into the positioning hole 22 in the opposite direction of the first direction X. This design makes the connection between the lid 20 and the assembly unit 10 consistent with the connection between the assembly units 10, maintaining the unity and coordination of the system.
[0112] In some embodiments, please refer to Figure 13 The number of assembly units 10 can be three, four or more, and multiple assembly units 10 are stacked along the first direction X after assembly. Different types of receiving structures can be provided inside the boxes 11 of different assembly units 10. For example, some boxes 11 have no other structures inside, forming a complete receiving space, which is convenient for storing large objects; or some boxes 11 have multiple partitions inside, dividing the box 11 into multiple small receiving spaces, which is convenient for storing small objects.
[0113] In some embodiments, the elastic element 142 may be a helical spring, which has good elasticity and durability. The spring force is carefully calculated to ensure sufficient locking force to prevent accidental disengagement, while also being controlled within a range that allows for easy operation by the user.
[0114] In some embodiments, the dimensions of the stop opening 1121 and the positioning opening 22 need to be precisely matched with the dimensions of the stop member 141. Typically, the depth of the stop opening 1121 is slightly larger than the protrusion length of the stop member 141 to ensure locking in place while avoiding excessive constraint. The width of the stop opening 1121 is slightly larger than the width of the stop member 141 to facilitate alignment and insertion without creating excessive gaps.
[0115] In some embodiments, to improve the user experience, anti-slip textures or eye-catching color markings can be provided at the force-bearing recess 1411 to facilitate quick identification and operation by the user.
[0116] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
