Description

Technical Field

[0001] The utility model relates to the technical field of connection, in particular to a connection component and a container stacking component. Background Art

[0002] A toolbox is a container for storing commonly used tools such as wrenches and pliers. Conventional toolboxes are generally used individually, but for easier transportation and storage, more and more toolboxes on the market adopt a stacking design, where multiple toolboxes are stacked together using an interlocking structure.

[0003] Due to the wide variety of tool types, toolboxes of different sizes also vary. However, existing toolboxes generally only allow toolboxes of the same size to be stacked (for details, see patents such as CN116214461A). Toolboxes of different sizes cannot be locked together because their designed latches do not match. In some usage scenarios, users want toolboxes of different sizes to be able to be stacked up and locked together for ease of use. Therefore, it is necessary to improve the structure of the toolbox so that it can be compatible with the stacking and interlocking of toolboxes of different sizes. Utility Model Content

[0034] like Figures 1 to 7 As shown, an embodiment of the present invention provides a connection assembly for connecting at least one first module 1 and at least one second module 2. The first module 1 and the second module 2 are adjacent to each other, for example, the first module 1 and the second module 2 are stacked up and down, or the first module 1 and the second module 2 are abutted left and right.

[0035] This solution is described by taking the first module 1 and the second module 2 stacked up and down as an example.

[0036] The connection components include:

[0037] The locking portion 3 is arranged on the first module 1, and the locking portion 3 includes multiple lock tongues 31; the locking portion 3 has a locking direction S1 and an unlocking direction S2, the locking direction S1 and the unlocking direction S2 are opposite directions, each lock tongue 31 extends along the locking direction S1, and the multiple lock tongues 31 are arranged at intervals along the locking direction S1 of the locking portion 3.

[0038] The engaging portion 4 is provided on the second module 2, protruding from the lower surface of the second module 2. The engaging portion 4 is configured to engage and lock with a locking tongue 31. In this application, the locking portion 3 is a sliding lock, capable of moving relative to the first module 1 in both a locking direction S1 and an unlocking direction S2. Because the multiple locking tongues 31 are spaced apart along the locking direction S1 of the locking portion 3, the multiple locking tongues 31 on the first module 1 can engage and lock with the engaging portions 4 on second modules 2 of different sizes.

[0039] The first module 1 and the second module 2 can be of the same or different sizes. The first module 1 and the second module 2 are adjacent, for example, stacked one above the other or positioned side by side. The connecting assembly can be used on containers, such as toolboxes, tool boxes, storage boxes, storage baskets, drawer boxes, roller boxes, tool bags, and the like. The connecting assembly can also be used on a rigid platform, such as a flatbed truck, external board, adapter board, workbench, or drawing board. The connecting assembly is primarily used to interlock the two modules. The first module 1 and the second module 2 can be containers, and the connecting assembly interlocks the containers. The first module 1 / second module 2 can be containers, and the second module 2 / first module 1 can be rigid platforms, and the connecting assembly interlocks the containers. The first module 1 and the second module 2 can be rigid platforms, and the connecting assembly interlocks the containers. The first module 1 and the second module 2 can be rigid platforms, and the connecting assembly interlocks the rigid platforms. In this embodiment, the first module 1 and the second module 2 are both containers.

[0040] like Figures 2 to 7 As shown, as an embodiment, the locking portion 3 is provided with two locking tongues 31, which can respectively engage and lock with the clamping portions 4 on at least two different sizes of second modules 2. Of course, in other embodiments, the locking portion 3 can also be provided with more locking tongues 31, such as three or four, so that it can interlock with the clamping portions 4 on more different sizes of second modules 2.

[0041] like Figure 2 and Figure 3 As shown, as an embodiment, locking portions 3 are provided on opposite sides of the first module 1, and engaging portions 4 are provided on opposite sides of the second module 2. Locking tongues 31 in the locking portions 3 on opposite sides can be respectively engaged and locked with the engaging portions 4 on opposite sides, and the locking directions S1 and unlocking directions S2 of the locking portions 3 on opposite sides are opposite. In other embodiments, a locking portion 3 can be provided on one side of the first module 1, and a fixed lock buckle (immovable) can be provided on the other side.

[0042] like Figures 4 to 6 As shown, as an embodiment, the locking portion 3 further includes an operating member 32, which is in transmission connection with the plurality of locking tongues 31. By manipulating the operating member 32, the locking tongues 31 can be driven to move in the locking direction S1 or the unlocking direction S2, thereby achieving locking or unlocking of the locking tongues 31.

[0043] like Figures 4 to 6As shown, as one embodiment, the locking portion 3 further includes a locking body 33, with multiple lock tongues 31 and an operating member 32 disposed on the locking body 33. The multiple lock tongues 31, the operating member 32, and the locking body 33 form an integrated structure, and the operating member 32 can drive the multiple lock tongues 31 to move simultaneously. In this embodiment, the operating member 32 is a handle disposed on the locking body 33. By manually depressing the operating member 32, the multiple lock tongues 31 can be synchronously moved. Furthermore, there is only one operating member 32, and the operating member 32 is located on one side of the multiple lock tongues 31 along the unlocking direction S2. That is, the operating member 32 is located at the outermost side of the multiple lock tongues 31, thereby facilitating unlocking at the outermost side without interference from the first module above. Furthermore, when the locking portion 3 is in the locked position, the operating member 32 does not protrude from the side wall of the first module 1 (the side wall refers to the side wall of the first module 1 on one side along the unlocking direction S2), thereby preventing the operating member 32 from being suspended during locking, thereby protecting the operating member 32 from damage. Of course, in other embodiments, there may be multiple operating members 32 , and the multiple operating members 32 respectively correspond to the multiple locking tongues 31 , and each operating member 32 is used to control the movement of the corresponding locking tongue 31 .

[0044] like Figure 3 and Figure 4 As shown, as an embodiment, the spacing T1 between two adjacent locking tongues 31 is not less than the width W of the clamping portion 4 in the locking direction S1. In certain application scenarios, when the second module 2 and the first module 1 are stacked on top of each other, the clamping portion 4 on the second module 2 can be smoothly placed between the two locking tongues 31, so that when the locking portion 3 moves toward the locking direction S1 to the locked position, the outer locking tongue 31 of the two adjacent locking tongues 31 can be engaged and locked with the clamping portion 4. Preferably, the spacing T1 between two adjacent locking tongues 31 is greater than the width W of the clamping portion 4 in the locking direction S1.

[0045] like Figure 2 、 Figure 4 and Figure 5As shown, as one embodiment, a mounting groove 11 is provided on the side edge of the first module 1. The locking portion 3 is disposed within the mounting groove 11 and is movable within the mounting groove 11. The locking portion 3 does not protrude from the upper surface of the first module 1. The inner sidewall of the mounting groove 11 includes a first inner sidewall 111 disposed opposite the notch of the mounting groove 11. When the locking portion 3 is in the unlocked position, the spacing T2 between the locking tongue 31 proximal to the first inner sidewall 111 (i.e., the innermost locking tongue 31 among the multiple locking tongues 31) and the first inner sidewall 111 is no less than the width W of the engaging portion 4 in the locking direction S1. In certain application scenarios, when the second module 2 and the first module 1 are stacked on top of each other, the engaging portion 4 on the second module 2 can be smoothly positioned between the innermost locking tongue 31 and the first inner sidewall 111, so that when the locking portion 3 moves toward the locking direction S1 to the locked position, the innermost locking tongue 31 can engage and lock with the engaging portion 4. Preferably, a distance T2 between the locking tongue 31 close to the first inner side wall 111 and the first inner side wall 111 is greater than a width W of the clamping portion 4 in the locking direction S1 .

[0046] like Figures 4 to 7 As shown, as an embodiment, a slide groove 10 is provided on the opposite sides of the installation groove 11 on the first module 1, and a guide portion 36 is provided on the opposite sides of the locking portion 3. The guide portions 36 on the opposite sides are respectively located in the slide grooves 10 on the opposite sides, and the guide portions 36 can slide along the slide grooves 10, thereby limiting the moving path of the locking portion 3.

[0047] like Figure 5 As shown, as an embodiment, the inner sidewall of the mounting groove 11 further includes a second inner sidewall 112, which is located between the first inner sidewall 111 and the notch of the mounting groove 11. A limiting rib 17 is provided on the second inner sidewall 112. The locking body 33 of the locking portion 3 is located below the limiting rib 17 and can abut against the limiting rib 17 in both directions. The limiting rib 17 can not only limit the movement path of the locking portion 3, but also limit the locking portion 3 in the vertical direction.

[0048] like Figures 5 to 7As shown, as an embodiment, a T-shaped rib 15 is provided on the bottom wall of the mounting groove 11, and a slidingly engaged T-shaped groove 37 is provided on the locking portion 3 (the T-shaped groove 37 is specifically provided on the lower surface of the locking portion 3). The T-shaped rib 15 is located within the T-shaped groove 37, and the T-shaped rib 15 and the T-shaped groove 37 slide together, which can not only limit the movement path of the locking portion 3, but also realize vertical load-bearing. At the same time, a stop bar 16 is provided on the bottom wall of the mounting groove 11. The stop bar 16 is located on one side of the T-shaped rib 15 along the locking direction S1 and is connected to the T-shaped rib 15. The stop bar 16 not only strengthens the T-shaped rib 15, but also abuts against the end of the T-shaped groove 37 when the locking portion 3 moves toward the locking direction S1 to the locked position, thereby preventing the locking portion 3 from moving further.

[0049] like Figures 5 to 7 As shown, as one embodiment, the locking portion 3 is provided with a first limiting portion 34 (specifically, the first limiting portion 34 is provided on the lower surface of the locking portion 3), and the mounting groove 11 is provided with a second limiting portion 12 and a third limiting portion 13 (specifically, the second limiting portion 12 and the third limiting portion 13 are provided on the bottom wall of the mounting groove 11). The second limiting portion 12 and the third limiting portion 13 are spaced apart along the locking direction S1. When the locking portion 3 is in the locked position, the first limiting portion 34 can engage with the third limiting portion 13 to maintain the locking portion 3 in the locked position; when the locking portion 3 is in the unlocked position, the first limiting portion 34 can engage with the second limiting portion 12 to maintain the locking portion 3 in the unlocked position.

[0050] like Figures 5 to 7 As shown, as one embodiment, the first limiting portion 34 is an elastic arm protruding from the locking portion 3. The elastic arm includes an elastic arm body 341 made of an elastic material. One end of the elastic arm body 341 is fixedly connected to the locking portion 3, while the other end of the elastic arm body 341 is suspended and provided with a protrusion 342. The second limiting portion 12 and the third limiting portion 13 are both limiting grooves provided on the first module 1. When the locking portion 3 is in the locked position, the protrusion 342 can engage with the third limiting portion 13. When the locking portion 3 is in the unlocked position, the protrusion 342 can engage with the second limiting portion 12.

[0051] like Figures 5 to 7 As shown, as an embodiment, a limit block 14 is further provided in the mounting groove 11 (specifically, the limit block 14 is provided on the bottom wall of the mounting groove 11), and the limit block 14 is parallel to the second limit portion 12. A stop portion 35 is provided on the locking portion 3 (specifically, the stop portion 35 is provided on the lower surface of the locking portion 3). When the locking portion 3 is in the unlocked position, the stop portion 35 can abut against the limit block 14, thereby preventing the locking portion 3 from falling out of the mounting groove 11.

[0052] Specifically, a stop surface 142 is provided on the side of the limit block 14 facing the locking direction S1. The stop surface 142 is a vertical surface. When the locking portion 3 is in the unlocked position, the stop portion 35 can abut against the stop surface 142 on the limit block 14. A first non-straight surface 141 is provided on the side of the limit block 14 facing the unlocking direction S2, and a second non-straight surface 351 is provided on the side of the stop portion 35 facing the locking direction S1. The first non-straight surface 141 and the second non-straight surface 351 can be inclined surfaces, curved surfaces, etc. When the locking portion 3 is installed in the installation slot 11, if the stop portion 35 interferes with the limit block 14, the first non-straight surface 141 contacts the second non-straight surface 351, so that the stop portion 35 can smoothly pass over the limit block 14, thereby facilitating the assembly of the locking portion 3.

[0053] like Figure 2 and Figure 3 As shown, as an embodiment, the first module 1 is provided with a plurality of positioning grooves 18, and the second module 2 is provided with a plurality of protrusions 21, and the plurality of protrusions 21 respectively correspond to the plurality of positioning grooves 18. When the second module 2 is stacked on top of the first module 1, the plurality of protrusions 21 on the second module 2 are respectively inserted into the plurality of positioning grooves 18 on the first module 1, thereby limiting the horizontal position of the first module 1 and the second module 2 and facilitating the positioning and assembly of the second module 2 and the first module 1.

[0054] like Figure 8 As shown, an embodiment of the present invention further provides a container stacking assembly, comprising at least one first container and at least one second container, the first container and the second container being connected by the aforementioned connecting assembly, i.e., one of the first container and the second container is the aforementioned first module 1, and the other is the aforementioned second module 2. The first container and the second container may be of the same or different sizes (the first module 1 may be larger or smaller than the second module 2).

[0055] The connection assembly provided by the embodiment of the present invention provides multiple locking tongues 31 on the locking portion 3 of the first module 1, and the multiple locking tongues 31 are spaced apart along the locking direction S1 of the locking portion 3, so that the multiple locking tongues 31 can respectively engage and lock with the clamping portions 4 on the second modules 2 of different sizes, thereby realizing stacking and interlocking between the first module 1 and the second modules 2 of different sizes, thereby greatly improving the convenience of use. Moreover, the connection assembly has a simple structure and fewer parts, which is not only convenient for assembly but also can reduce costs.

[0056] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
