Description

Technical Field

[0001] This invention belongs to the field of toolbox technology, and specifically relates to toolbox combinations with multiple stacking methods. Background Technology

[0002] Currently, existing toolbox stacking methods are limited. One method involves vertical stacking or horizontal connection between toolboxes of the same size. Another method, when stacking vertically, uses horizontal limiting components to connect the upper and lower toolboxes. This latter method only requires that the bottom dimensions of the stacked toolboxes be identical, not necessarily their height dimensions. However, existing toolboxes vary in size, making it impossible to combine two toolboxes with different bottom dimensions. Furthermore, when two parallel toolboxes are placed on a large toolbox, the two upper toolboxes are not connected and can easily detach from the lower toolbox during transport, hindering transportation. In short, the combination methods achievable with existing toolbox structures are not convenient enough in practical use. Summary of the Invention

[0003] This invention provides a toolbox combination with multiple stacking methods, solving the problem of difficulty in combining boxes of different sizes.

[0004] The technical solution adopted by this invention to solve its technical problem is: a toolbox assembly with multiple stacking methods, including several first toolboxes, several second toolboxes, several third toolboxes, a rotating connector, and several limiting components, wherein: The second and third toolboxes have the same bottom dimensions. The height dimension of the second toolbox is half the height dimension of the third toolbox. The length dimension of the bottom surface of the second and third toolboxes is the same as the width dimension of the bottom surface of the first toolbox. The maximum width dimension of the bottom surface of the second and third toolboxes is half the length dimension of the bottom surface of the first toolbox. The limiting components are set on both sides of the top surface of the first toolbox in the width direction and on one side of the top surface of the second and third toolboxes in the length direction; A slot is made in the middle of the top surface of the first toolbox, and the rotating connector is locked in the slot and rotates in the slot about the length of the slot as the axis of rotation; The toolbox combination includes the following three combinations, as detailed below: A first toolbox, two second toolboxes, and a third toolbox form a first assembly. The first assembly is assembled as follows: a limiting component on the first toolbox connects the third toolbox to the first toolbox, allowing the third toolbox to be positioned above the first toolbox; the two second toolboxes are stacked vertically via limiting components on the lower second toolbox, and the lower second toolbox is connected to the first toolbox via another limiting component, thus placing the two second toolboxes above the first toolbox, with the two second toolboxes and the third toolbox side-by-side; simultaneously, a rotating connector rotates to a position perpendicular to the top surface of the first toolbox, with the bottom surface of the lower second toolbox near the third toolbox engaging with one end of the rotating connector, and the bottom surface of the third toolbox near the second toolbox engaging with the other end of the rotating connector, thus connecting the lower second and third toolboxes; the first assembly can be used alone, or at least one additional first assembly can be stacked vertically. A first toolbox and two second toolboxes form a second assembly. The second assembly is assembled as follows: a limiting component on the first toolbox connects one second toolbox to the first toolbox, so that the second toolbox is positioned above the first toolbox; another limiting component on the first toolbox connects another second toolbox to the first toolbox, so that the second toolbox is positioned above the first toolbox, and the two second toolboxes are placed side by side; simultaneously, a rotating connector rotates to a position perpendicular to the top surface of the first toolbox, and the bottom surfaces of the two second toolboxes near the rotating connector mate with the two ends of the rotating connector to form a connection, thus connecting the two second toolboxes; the second assembly can be used alone, or at least one second assembly can be stacked vertically. A first toolbox and two third toolboxes form a third combination. The third combination is assembled as follows: a limiting component on the first toolbox connects one third toolbox to the first toolbox, so that the third toolbox is assembled on top of the first toolbox; another limiting component on the first toolbox connects another third toolbox to the first toolbox, so that the third toolbox is assembled on top of the first toolbox, and the two third toolboxes are side by side; at the same time, the rotating connector rotates to a position perpendicular to the top surface of the first toolbox, and the bottom surfaces of the two third toolboxes near the rotating connector mate with the two ends of the rotating connector to form a connection, so that the two third toolboxes are connected; the third combination can be used alone, or at least one third combination can be stacked vertically.

[0006] As a further preferred embodiment of the present invention, the rotary connector includes a rotary connector body, with outwardly extending portions on both sides of one end of the rotary connector body forming a first snap-fit ​​end. The first snap-fit ​​end cooperates with a slot to enable the rotary connector to rotate within the slot with the direction of the first snap-fit ​​end as the rotation center. The outwardly extending portions on both sides of the other end of the rotary connector body form a second snap-fit ​​end. The two ends of the second snap-fit ​​end cooperate with the second limiting clips on the two second toolboxes, or with the second limiting clips on the two third toolboxes, or with the second limiting clips on one second toolbox and one second limiting clip on one third toolbox.

The first snap-fit ​​part cooperates with the first limiting snap-fit ​​member. An elastic snap-fit ​​member is provided at the bottom of the push-pull member. The elastic snap-fit ​​member can cooperate with any of the limiting groove groups.

[0010] As a further preferred embodiment of the present invention, a first toolbox and a second toolbox form a fourth assembly. The rotating connector is rotated to a state parallel to the top surface of the first toolbox. The second toolbox is arranged along the length direction of the first toolbox on the top surface of the first toolbox. The connection between the second toolbox and the first toolbox is realized through two limiting components on the first toolbox. The fourth assembly can be used alone, or a second toolbox or a third toolbox can be assembled above the second toolbox of the fourth assembly, or any number of other first toolboxes can be assembled below the first toolbox of the second assembly. A first toolbox and a third toolbox form a fifth assembly. The rotating connector is rotated to be parallel to the top surface of the first toolbox.

[0011] By employing the above technical solutions, the present invention has the following beneficial effects compared to the prior art: 1. This invention includes five combination methods, which are diverse and the three types of toolboxes can be combined arbitrarily.

[0020] This embodiment provides a preferred implementation, a toolbox combination with multiple stacking methods, such as... Figures 1 to 17 As shown, this toolbox assembly includes several first toolboxes 1, several second toolboxes 2, several third toolboxes 3, a rotating connector 4, and several limiting components 5, wherein: The second toolbox 2 and the third toolbox 3 have the same bottom dimensions. The height dimension of the second toolbox 2 is half the height dimension of the third toolbox 3. The length dimension of the bottom surface of the second toolbox 2 and the third toolbox 3 is the same as the width dimension of the bottom surface of the first toolbox 1. The width dimension of the bottom surface of the second toolbox 2 and the third toolbox 3 is at most half the length dimension of the bottom surface of the first toolbox 1.

[0021] The aforementioned limiting components 5 are located on both sides of the top surface of the first toolbox 1 in the width direction and on one side of the top surface of the second toolbox 2 and the third toolbox 3 in the length direction. A slot 6 is opened in the middle of the top surface of the first toolbox 1, and the rotating connector 4 is engaged in the slot 6 and rotates within the slot 6 about the length direction of the slot 6.

[0022] The toolbox combination includes the following five combinations, as detailed below: A first toolbox 1, two second toolboxes 2, and a third toolbox 3 form a first assembly. The first assembly is assembled as follows: a limiting component 5 on the first toolbox 1 connects the third toolbox 3 to the first toolbox 1, allowing the third toolbox 3 to be positioned on top of the first toolbox 1; the two second toolboxes 2 are stacked vertically via limiting components 5 on the lower second toolbox 2, and the lower second toolbox 2 of the assembled assembly is connected to the first toolbox 1 via another limiting component 5, thus completing the assembly. Two second toolboxes 2 are combined above the first toolbox 1, and the two second toolboxes 2 are side by side with the third toolbox 3; at the same time, the rotating connector 4 is rotated to a position perpendicular to the top surface of the first toolbox 1, and the bottom surface of the second toolbox 2 below, near the third toolbox 3, is connected to one end of the rotating connector 4, and the bottom surface of the third toolbox 3 below, near the second toolbox 2, is connected to the other end of the rotating connector 4, thus realizing the connection between the second toolbox 2 below and the third toolbox 3; the first combination can be used alone, or at least one more first combination can be stacked vertically.

[0023] A first toolbox 1 and two second toolboxes 2 form a second combination. The combination method of the second combination is as follows: a limiting component 5 on the first toolbox 1 connects one second toolbox 2 to the first toolbox 1, so that the second toolbox 2 is combined above the first toolbox 1; another limiting component 5 on the first toolbox 1 connects another second toolbox 2 to the first toolbox 1, so that the second toolbox 2 is combined above the first toolbox 1, and the two second toolboxes 2 are side by side; at the same time, the rotating connector 4 is rotated to a state perpendicular to the top surface of the first toolbox 1, and the bottom surface of the two second toolboxes 2 close to the rotating connector 4 is connected with the two ends of the rotating connector 4 to form a connection between the two second toolboxes 2; the second combination can be used alone, or at least one second combination can be stacked vertically.

[0024] A first toolbox 1 and two third toolboxes 3 form a third combination. The combination method of the third combination is as follows: a limiting component 5 on the first toolbox 1 connects one third toolbox 3 to the first toolbox 1, so that the third toolbox 3 is combined above the first toolbox 1; another limiting component 5 on the first toolbox 1 connects another third toolbox 3 to the first toolbox 1, so that the third toolbox 3 is combined above the first toolbox 1, and the two third toolboxes 3 are side by side; at the same time, the rotating connector 4 is rotated to a state perpendicular to the top surface of the first toolbox 1, and the bottom surface of the two third toolboxes 3 near the rotating connector 4 is connected with the two ends of the rotating connector 4 to form a connection between the two third toolboxes 3; the third combination can be used alone, or at least one third combination can be stacked vertically.

[0025] A first toolbox 1 and a second toolbox 2 form a fourth assembly. The rotating connector 4 is rotated to be parallel to the top surface of the first toolbox 1. The second toolbox 2 is arranged along the length of the first toolbox 1 on the top surface of the first toolbox 1. The connection between the second toolbox 2 and the first toolbox 1 is achieved through two limiting components 5 on the first toolbox 1. The fourth assembly can be used alone, or the second toolbox 2 or the third toolbox 3 can be combined above the second toolbox 2 of the fourth assembly, or any number of other first toolboxes 2 can be combined below the first toolbox 2 of the second assembly.

[0026] A first toolbox 1 and a third toolbox 3 form a fifth assembly. The rotating connector 4 is rotated to be parallel to the top surface of the first toolbox 1. The third toolbox 3 is arranged along the length of the first toolbox 1 on the top surface of the first toolbox 1. The connection between the third toolbox 3 and the first toolbox 1 is achieved through two limiting components 5 on the first toolbox 1. The fifth assembly can be used alone, or a second toolbox 2 or a third toolbox 3 can be combined above the third toolbox 3 of the fifth assembly, or any number of other first toolboxes 2 can be combined below the first toolbox 2 of the fifth assembly.

[0027] To further facilitate the connection between toolboxes, this embodiment also includes several first limiting clips 7 that cooperate with the limiting component 5, several second limiting clips 8 that cooperate with the rotating connector 4, and several third limiting clips 9 that cooperate with the second limiting clips 8. First limiting clips 7 are provided on both sides of the bottom width of the first toolbox 1, one side of the bottom length of the second toolbox 2, and one side of the bottom length of the third toolbox 3; second limiting clips 8 are provided on the other side of the bottom length of the second toolbox 2 and the other side of the bottom length of the third toolbox 3; third limiting clips 9 are provided on the side of the top surface of the second toolbox 2 facing away from the limiting component 5 and the side of the top surface of the third toolbox 3 facing away from the limiting component 5.

[0028] The aforementioned rotary connector 4 includes a rotary connector body 10. One end of the rotary connector body 10 extends outwards on both sides to form a first engaging end 11. The first engaging end 11 engages with a slot 6 to allow the rotary connector 4 to rotate within the slot 6 about its length. Preferably, the slot 6 has a mounting portion 21 that engages with the first engaging end 11. The two ends of the first engaging end 11 are cylindrical. The first engaging end 11 engages within the mounting portion 21 of the slot 6, limiting its position and simultaneously connecting the rotary connector 4 to the first toolbox 1. The other end of the rotary connector body 10 extends outwards on both sides to form a second engaging end 12. The two ends of the second engaging end 12 engage with second limiting clips 8 on two second toolboxes 2, or with second limiting clips 8 on two third toolboxes 3, or with a second limiting clip 8 on one second toolbox 2 and a second limiting clip 8 on one third toolbox 3. The rotating connector body 10 rotates within the slot 6 around the first snap-fit ​​end 11, thereby switching between a state parallel to the top surface of the first toolbox 1 and a state perpendicular to the top surface of the first toolbox 1. When the rotating connector body 10 is parallel to the top surface of the first toolbox 1, it rotates until it is completely within the slot 6, at which point it is completely hidden inside the first toolbox 1. When the rotating connector body 10 is perpendicular to the top surface of the first toolbox 1, it protrudes from the slot 6, facilitating the connection of the second snap-fit ​​end 12 of the rotating connector body 10 with other toolboxes.

[0029] The aforementioned limiting component 5 includes a limiting platform 13 and a push-pull component 14. The limiting platform 13 has a groove in its center for easy installation of the push-pull component 14. At least two sets of limiting groove groups 16 are provided at the bottom of the groove on the limiting platform 13. A portion is cut off on one side of the push-pull component 14 to form a first engaging portion 17 with a U-shaped cross-section. The first engaging portion 17 cooperates with the first limiting locking component 7. An elastic locking component 18 is provided at the bottom of the push-pull component 14. The elastic locking component 18 can cooperate with any of the limiting groove groups 16. The position of the push-pull component 14 on the limiting platform 13 can be adjusted by adjusting which limiting groove group 16 the elastic locking component 18 cooperates with.

[0030] Specifically, the inwardly extending portion of the top of the limiting platform 5 forms a groove edge 22, thereby limiting the push-pull member 14 to the limiting platform 5. The two sides of the bottom surface of the limiting platform 5 are set in a stepped shape, and the two ends of the push-pull member 14 are stepped. The stepped structure of the push-pull member 14 cooperates with the stepped structure of the limiting platform 5 to realize the structural connection between the limiting platform 5 and the push-pull member 14.

[0031] In order to prevent the push-pull component 14 from completely detaching from the limiting platform 5 during the movement, this implementation scheme sets two blocking blocks 23 on the limiting platform 5, thereby limiting the farthest position that the push-pull component 14 can move outward, and ensuring that the push-pull component 14 will not completely detach from the limiting platform 5.

[0032] To prevent displacement during the relative position adjustment between the push-pull component 14 and the limiting platform 13, this embodiment further includes at least one guide block 15 and at least one mounting groove 19. Preferably, two guide blocks 15 are provided, distributed on both sides of the limiting groove group 16. The guide blocks 15 are disposed within the limiting platform 13 along the width direction of the limiting platform 13, and the orientation of the guide blocks 15 is the moving direction of the push-pull component 14. The mounting groove 19 is formed on the push-pull component 14, and the mounting groove 19 cooperates with the guide blocks 15 to connect the push-pull component 14 and the limiting platform 13, and provides guidance for the movement of the push-pull component 14, ensuring that the moving direction of the push-pull component 14 is always in the required direction and that no lateral displacement occurs.

[0033] The aforementioned elastic locking member 18 has an L-shaped structure, with its longer side parallel to the limiting platform 13. At least one protrusion 20 is provided at the bottom of the longer side of the elastic locking member 18. The limiting groove group 16 has two limiting grooves, which engage with the protrusions 20 on the elastic locking member 18. When the push-pull member 14 moves to the point where the protrusion 20 on the elastic locking member 18 is located in a limiting groove of the limiting groove group 16 away from the blocking block 23, the relative position between the push-pull member 14 and the limiting platform 13 is limited. When two protrusions 20 are provided, when the push-pull member 14 moves to the point where both protrusions 20 on the elastic locking member 18 are simultaneously located in the two limiting grooves of the limiting groove group 16, the relative position between the push-pull member 14 and the limiting platform 13 is limited. Preferably, in each limiting groove group 16, the limiting groove closest to the blocking block 23 is angled towards the other limiting groove, thereby facilitating better passage of the protrusion 20 through this limiting groove. Because the elastic clip 18 has a certain elasticity, when it is necessary to adjust the push-pull clip 14 to cooperate with another set of limiting grooves 16, push the push-pull clip 14 with force so that the push-pull clip 14 can be disengaged from the current limiting groove 16 and then moved to cooperate with the next set of limiting grooves 16.

[0034] Furthermore, in this embodiment, the first toolbox 1 can be manufactured in various sizes, provided that the minimum length dimension of the bottom surface of the first toolbox 1 is the sum of the width dimensions of the second toolbox 2 and the third toolbox 3; there are no requirements for the height dimension of the first toolbox 1. When several first toolboxes 1 are stacked together, it is sufficient that the top surface dimension of the lower first toolbox 1 is always greater than or equal to the bottom surface dimension of the upper first toolbox 1; there are no requirements for the height dimension. Figure 5As shown, two different sizes of first toolboxes 1 can be stacked below the first assembly. Even if there is a difference in the bottom dimensions between the two toolboxes, it is only necessary to change the dimensions of the limiting platform 13 and set up more sets of limiting slots 16 to ensure that the limiting component 5 can connect the upper and lower toolboxes together.

[0035] The fourth and fifth combinations described above, because the bottom surface size of the upper toolbox is smaller than that of the lower toolbox, are assembled by setting multiple limiting slots 16 in the limiting platform 13. The push-pull component 14 is pushed to the appropriate limiting slot 16 position to achieve the assembly of the fourth and fifth combinations. In other words, in this application, the limiting platform 13 on the first toolbox 1 is designed to the maximum achievable size, i.e., the maximum number of limiting slots 16 that can be designed, thus allowing for the connection between various toolboxes with a matching number of limiting slots 16. It is evident that this embodiment has wide applicability and diverse combinations, meeting various market demands. Furthermore, the design of the limiting component 5 not only satisfies the matching between toolboxes of the same size but also the connection between toolboxes of multiple sizes.
