[0002] A tool box is a container for storing commonly used tools such as wrenches and pliers. Conventional tool boxes are generally used alone. In order to facilitate transportation and storage, more and more tool boxes on the market adopt a stacking design structure, using multiple tool boxes stacked up and down to store more tool boxes in a limited space, thereby improving space utilization.

[0003] Due to the variety of tool types, tool boxes of different types have different sizes. However, existing tool boxes are generally only able to achieve stacking of tool boxes of the same size (for details, please refer to patents such as CN116214461A), and tool boxes of different sizes cannot be locked with each other because their designed card positions do not match. In some usage scenarios, users hope that tool boxes of different sizes can also be stacked up and down and locked with each other for easy use. Therefore, it is necessary to improve the structure of the tool box so that it can be compatible with the stacking and interlocking of tool boxes of different sizes. Utility Model Content

[0029] The directional words such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the specification and claims of the utility model are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are only for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional words should not limit the scope of protection claimed by the utility model.

[0030] like Figures 1 to 6As shown, an embodiment of the utility model provides an interlocking structure, including a limiting portion 2 and a lock buckle 3 arranged opposite to each other at intervals on the surface of one side of a box body 1 of a tool box 100, and at least one clamping group 4 arranged on the surface of one side of the box body 1 of another tool box 100, the lock buckle 3 can lock and unlock; the clamping group 4 includes a first clamping portion 41 and a second clamping portion 42 arranged opposite to each other at intervals, the first clamping portion 41 and the second clamping portion 42 have relative openings (in other embodiments, in order to meet the requirements of different locking directions of the limiting portion 2 and the lock buckle 3, the opening directions of the first clamping portion 41 and the second clamping portion 42 can be adaptively adjusted), the first clamping portion 41 is used to engage with the limiting portion 2 on the other tool box 100, and the second clamping portion 42 is used to engage and lock with the lock buckle 3 on the other tool box 100. The two tool boxes 100 can be stacked up and down and interlocked through the interlocking structure, and the two tool boxes 100 have different sizes (wherein, tool boxes 100 of different sizes generally refer to different widths and / or lengths; and the tool boxes 100 are generally stacked along the height direction H, so the height difference generally does not affect the stacking of the tool boxes 100). When the two tool boxes 100 are interlocked, the spacing distance between a first clamping portion 41 and a second clamping portion 42 on one tool box 100 is equal to the spacing distance between the limiting portion 2 and the lock buckle 3 on the other tool box 100, so that the first clamping portion 41 and the second clamping portion 42 can be smoothly engaged with the limiting portion 2 and the lock buckle 3 respectively.

[0031] Specifically, the interlocking structure provided in this embodiment is achieved by providing a limiting portion 2 and a lock 3 on the surface of one side of the box body 1 of a tool box 100, and providing a locking group 4 on the surface of one side of the box body 1 of another tool box 100, each locking group 4 includes a first locking portion 41 for engaging with the limiting portion 2 and a second locking portion 42 for engaging with the lock 3, thereby achieving stacking interlocking between tool boxes 100 of different sizes and improving convenience of use.

[0032] like Figures 1 to 4 As shown, as an embodiment, a limiting portion 2 and a lock 3 are provided on the surface of one side of the box body 1 of each tool box 100, and at least one locking group 4 is provided on the surface of the other side of the box body 1 of each tool box 100, thereby allowing any two tool boxes 100 to be stacked up and locked with each other.

[0033] like Figures 1 to 4As shown, as an embodiment, the interlocking structure includes a plurality of latching positions groups 4, wherein the first latching portions 41 and / or the second latching portions 42 in the plurality of latching positions groups 4 are respectively arranged at different positions on the surface of the box body 1 (i.e., the arrangement position of at least one of the first latching portions 41 and the second latching portions 42 of every two latching positions groups 4 is different), and wherein at least a portion of the latching positions groups 4 (at least one) are used for the interlocking of tool boxes 100 of different sizes when they are stacked. Specifically, in this embodiment, among the plurality of latching positions groups 4, a portion (at least one) of the latching positions groups 4 are used for the interlocking of tool boxes 100 of the same size when they are stacked (of course, this portion of the latching positions groups 4 can also be used for the interlocking of tool boxes 100 of different sizes when they are stacked), and another portion of the latching positions groups 4 (at least one) are used for the interlocking of tool boxes 100 of different sizes when they are stacked.
