[0043] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0044] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0045] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0046] This utility model provides a toolbox assembly. For the sake of brevity, this specification only uses two adjacent stacked toolboxes as examples, and does not imply that the toolbox assembly of this utility model includes only two toolboxes. Furthermore, this specification only describes two identical toolboxes; therefore, the identical parts of the toolboxes are only explained in detail using one of the toolboxes. Alternatively, describing the structure of the first toolbox separately can also be applied to the structure of the second toolbox.

[0047] refer to Figures 1 to 8 This utility model provides a toolbox assembly, including a first toolbox 100 and a second toolbox 200, wherein the first toolbox 100 can be stacked on the second toolbox 200 and can be locked to each other.

[0048] Specifically, the first toolbox 100 (second toolbox 200) includes a box body 20 and a lid 10. The lid 10 is hinged to the box body 20 and is rotatable relative to the box body 20, transitioning between an open / closed state and a closed state. In the closed state, the lid 10 and the box body 20 form a fixed receiving space for storing various items. Figure 3 As shown, a locking mechanism 30 is provided between the lid 10 and the box 20, which locks the lid 10 and the box 20 in a closed state. In this embodiment, the first toolbox 100 has two locking mechanisms 30 arranged symmetrically with respect to the container 100 axis for stable locking. The locking mechanism 30 can be a conventional snap-on lock structure, a latch lock structure, a magnetic lock structure, or a combination lock structure, etc., which will not be described in detail here.

[0049] Continue to refer to Figures 3 to 5 The first toolbox 100 includes a positioning recess 40. The positioning recess 40 is recessed from a first surface 101 of the first toolbox 100 along a first direction. In this embodiment, the first direction is perpendicular to and oriented towards the first surface 101, which is the outer surface of the top of the cover 10. Specifically, the positioning recess 40 includes a recessed surface 401, a first sidewall 42, a second sidewall 44, and a third wall 46. The first sidewall 42, the second sidewall 44, and the third wall 46 extend around the recessed surface 401 along a second direction to a first predetermined depth, such that a notch 48 is formed on one side of the positioning recess 40. The second direction is also perpendicular to the first surface 101, and the first direction is opposite to the second direction.

[0050] refer to Figures 6 to 8As shown, the second toolbox includes a positioning protrusion 43. The positioning protrusion 43 protrudes from the second surface 202 of the second toolbox 200 along a second direction. In this embodiment, the second surface 202 is the outer surface of the bottom of the box body 20. The positioning protrusion 43 includes a protruding surface 431, a first vertical wall 432, a second vertical wall 434, a third vertical wall 436, and a fourth vertical wall 438. The first vertical wall 432, the second vertical wall 434, the third vertical wall 436, and the fourth vertical wall 438 extend a first preset height around the protruding surface 431 along a first direction and connect to the second surface 202, so that the outer contour of the positioning protrusion 43 is closed. In a specific embodiment, the positioning protrusion 43 can be integrally injection molded with the second surface of the second toolbox 200, or it can be divided into two parts and locked together with screws; no limitation is made here.

[0051] Furthermore, the first toolbox 100 also includes a locking male component 50, and the second toolbox 200 includes a locking female component 53 that can be adapted to the locking male component 50. When the locking male component 50 of the first toolbox 100 and the locking female component 53 of the second toolbox 200 are locked together, the positioning protrusion 43 can be completely accommodated in the positioning recess 40, thereby effectively positioning the second toolbox 200 and the first toolbox 100.

[0052] Continue to refer to Figures 3 to 5 In this embodiment, the first sidewall 402 and the second sidewall 404 are located on opposite sides, and the third wall 406 and the notch 408 are located on opposite sides, with the notch 408 being closer to the outer side of the first toolbox 100. The notch 408 being located on the outer side corresponds to the positioning recess 40 having an opening facing the outer side of the first toolbox 100, thereby facilitating the sliding of the positioning protrusion 43 into or out of the positioning recess 40 during assembly or disassembly with the second toolbox 200.

[0053] In a preferred embodiment, reference Figures 3 to 8 The positioning recess 40 also includes a positioning rib 42. The positioning rib 42 is located on the first sidewall 402 or the second sidewall 402, and extends from the third wall 406 above the recessed surface 401. The positioning protrusion 43 also includes a positioning tongue 45, which is located on the first vertical wall 432 or the second vertical wall 434, and is below the protruding surface 431. When the first toolbox 100 and the second toolbox 200 are assembled, the positioning rib 42 can engage with the positioning tongue 45.

[0054] Preferably, there are two positioning ribs 42, located on the first sidewall 402 and the second sidewall 404 respectively, and the positions of the two positioning ribs 42 are symmetrical. Correspondingly, there are two positioning tongues 45, located on the first vertical wall 432 and the second vertical wall 434 respectively, and the positions of the two positioning tongues 45 are symmetrical. The two symmetrically arranged positioning ribs and positioning tongues provide lateral locking of the positioning protrusion and the positioning recess from two sides, further stabilizing the positioning combination between the first toolbox 100 and the second toolbox 200. In this specific embodiment, the positioning ribs 42 are plate-shaped, and the positioning tongues 45 are slits. When the first toolbox 100 and the second toolbox 200 are assembled, the positioning ribs 42 can be inserted into the two slits respectively.

[0055] Continue to refer to Figures 3 to 8 In this embodiment, the surface area of ​​the recessed surface 401 is greater than or equal to the surface area of ​​the raised surface 431. This can be understood as the length of the positioning protrusion 43 being the same as or slightly smaller than the length of the positioning recess 40, and the width of the positioning protrusion 43 being smaller than the width of the positioning recess 40. In this embodiment, the matching of the positioning protrusion 43 and the positioning recess 40 is limited using only one dimension, thereby ensuring that the area of ​​the positioning recess 40 is larger than the area of ​​the positioning protrusion 43 during toolbox manufacturing, thus minimizing the weight of the toolbox. Of course, in other embodiments, the width of the positioning protrusion 43 may be the same as or slightly smaller than the width of the positioning recess 40, and the length of the positioning protrusion 43 may be smaller than the width of the positioning recess 40.

[0056] In one embodiment, the positioning protrusion 43 has an irregular shape, and the positioning recess 40 also has an irregular shape. Specifically, the positioning protrusion 43 is octagonal, and the positioning recess 40 is also an octagon with a uniform length. Correspondingly, the first sidewall 402 may include three octagonal sidewalls, the second sidewall 404 includes three opposing octagonal sidewalls, the third sidewall 406 is one sidewall connecting the first sidewall 402 and the second sidewall 404, and the notch 408 is another octagonal sidewall. The first vertical wall 432 may include three octagonal sidewalls, the second vertical wall 434 includes three opposing octagonal sidewalls, the third vertical wall 436 is one sidewall connecting the first vertical wall 432 and the second vertical wall 434, and the fourth vertical wall 438 is another octagonal sidewall.

[0057] In a preferred embodiment, the positioning recess 40 further includes a stop block 60. The stop block 60 protrudes from the recess surface 401 along a first direction and extends a second preset height to limit the extreme position of the positioning protrusion 43 when it is accommodated in the positioning recess 40. In a specific embodiment, the stop block 60 is a prismatic protrusion, and the value of the second preset height is less than or equal to the value of the first preset depth, that is, the height of the stop block 60 can be approximately the same as the height of the positioning protrusion 43. When the positioning protrusion 43 is positioned with the positioning recess 40 in only one dimension, the stop block 60 can be positioned to limit the positioning protrusion 43 in another dimension, ensuring the positioning stability between the two adjacent containers 100.

[0058] Preferably, the first toolbox 100 includes a plurality of positioning recesses 40, and the plurality of positioning recesses 40 are symmetrical about the first toolbox 100; correspondingly, the second toolbox 200 includes the same number of positioning protrusions 43 as the first toolbox 100 includes positioning recesses 40, and their positions correspond to each other. Figures 1 to 8 In this embodiment, the first toolbox 100 includes four positioning recesses 40, and the second toolbox 200 includes four positioning protrusions 43. Of course, in other embodiments, the number of positioning recesses 40 and positioning protrusions 43 can also be other numbers, such as two, three, or other multiples.

[0059] Continue to refer to Figures 3 to 8 In this embodiment, the male locking component 50 is disposed on the lid 10 of the first toolbox 100, and the female locking component 53 is disposed on the box 20 of the second toolbox 200. The female locking component 53 and the male locking component 50 can cooperate with each other to lock the box 20 and lid 10 of the two containers 100. The male locking component 50 and the female locking component 53 can realize the locking and unlocking between the lid 10 and the box 20, effectively realizing the locking and unlocking function of two adjacent stacked first toolboxes 100 and second toolboxes 200, thus not only satisfying the stability guarantee of multiple toolboxes stacked vertically, but also taking into account the convenience of loading and unloading.

[0060] Preferably, the locking female component 53 and the locking male component 50 are positioned on the same side as the locking mechanism 30, and the distance from the side edge of the position is less than 10 cm, so as to facilitate manual operation by the user.

[0061] In this embodiment, the locking male component 50 includes an elastic element (not shown in the figure) and a locking element. The elastic element is disposed below the locking element, and the locking element can generate a preset displacement relative to the outer surface of the cover 10 under the elastic force of the elastic element. The elastic element can be a spring, with one end of the spring embedded in a hole in the cover 10 and the other end of the spring embedded in the bottom of the locking element; specifically, the spring can be a plastic spring, a metal spring, a metal wire spring, etc. The locking female component 53 is a groove, the shape of which is adapted to the shape of the locking element. Specifically, the locking element includes a protrusion 503 and a flat portion 501. The protrusion 503 is triangular in shape, and the groove 53 is triangular in shape. Under the elastic force of the spring, the protrusion 503 can abut into the groove 53, thereby locking the two adjacent stacked containers 100. Further, the platform portion 501 is provided with a finger hole 5012 to facilitate the user to manually unlock the locking male component 50 and the locking female component 53. The user can insert their finger into the finger hole 5012, which compresses the spring in the flat part 501, causing the protrusion 53 to shift relative to the outer surface of the cover 10, thus freeing it from the groove. Furthermore, a finger hole 102 is provided on the cover 10, and the finger hole 102 is located below the finger hole 5012. By providing a corresponding finger hole 102 on the cover 10, which cooperates with the finger hole 5012, the user's operating space is increased, further facilitating the unlocking operation.

[0062] refer to Figures 1 to 2 As shown, the toolbox assembly provided in this embodiment includes a first toolbox 100 and a second toolbox 200, which are detachably connected and disconnected.

[0063] During the assembly of the first toolbox 100 and the second toolbox 200, the first toolbox 100 can slide along the width direction from the notch 48 and stack on top of the second toolbox 200. When the positioning protrusion 43 is recessed in the positioning recess 40, the locking rib 42 is inserted into the locking tongue 45 along the width direction. This not only positions the first toolbox 100 in the preset position of the second toolbox 200, but also provides a certain locking and anti-shaking function. Under the pressure of the weight of the second toolbox 200, the elastic element in the locking male part 50 on the cover 10 of the first toolbox 100 is compressed. When the locking female part 53 of the second toolbox 200 is pushed to the position above the locking male part 50, the protrusion 503 is embedded into the locking female part 53 (i.e., the groove) under the restoring force of the elastic element, thereby locking the second toolbox 200 and the first toolbox 100 together.

[0064] When the first toolbox 100 and the second toolbox 200 need to be unloaded or disassembled, the user first inserts his / her fingers into the finger holes and / or finger openings, and moves the flat part toward the surface of the cover 10 of the first toolbox 100, so that the protrusion is disengaged from the locking female part (i.e., the groove); after the locking male part and the locking female part are unlocked, the first toolbox 100 is pushed along the width direction, so that the positioning protrusion can be pushed out of the positioning recess to break the positioning restriction.

[0065] The toolbox assembly provided by this utility model includes a first toolbox 100 with a positioning recess 40 and a second toolbox 200 with a positioning protrusion 43, thereby enabling the positioning of two adjacent stacked first toolboxes 100 and second toolboxes 200. Simultaneously, the first toolbox 100 also has a locking male component 50, and the second toolbox 200 has a locking female component 53, thereby enabling the locking and unlocking of two adjacent stacked first toolboxes 100 and second toolboxes 200. Furthermore, a notch 408 is formed on one side of the positioning recess 40, allowing the positioning protrusion 43 of the second toolbox 200 to easily slide into or out of the positioning recess 40 during loading and unloading. This not only ensures the stability of multiple stacked toolboxes but also considers the convenience of loading and unloading.

[0066] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
