Description

Technical Field

[0001] This utility model relates to the field of connection technology, and in particular to a connection component and a container stacking component. Background Technology

[0002] A toolbox is a container used to store commonly used tools such as wrenches and pliers. While conventional toolboxes are usually used individually, for ease of transport and storage, an increasing number of toolboxes on the market adopt a stacking design, with multiple toolboxes using an interlocking mechanism to be stacked vertically.

[0003] Current stackable toolboxes typically have locking mechanisms on opposite sides of one toolbox and corresponding locking mechanisms on opposite sides of another toolbox. The locking and locking mechanisms engage to achieve interlocking between the two toolboxes (see patents such as CN216995407U for details). However, this structure requires locking mechanisms on both sides of the toolbox, increasing structural complexity and hindering manufacturing. Furthermore, unlocking requires manually unlocking the locking mechanisms on both sides, which is inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a connection component that is not only simple in structure but also easy to unlock.

[0005] This utility model provides a connecting component for connecting at least one first module and at least one second module, the connecting component comprising:

[0006] A first locking tongue and a movable latch are spaced apart and positioned opposite each other on the first module; the movable latch includes a second locking tongue, the first locking tongue is fixed to the first module, and the second locking tongue is movable relative to the first module; the movable latch has a locked state and an unlocked state.

[0007] At least one card slot group includes a first card contact portion and a second card contact portion that are spaced apart and oppositely disposed on the second module;

[0008] When the first module and the second module are locked together, the first locking tongue interferes with the first locking part, the movable latch is in a locked state, and the second locking tongue interferes with the second locking part.

[0009] In one possible implementation, the first latch and the second latch extend in the same direction, and the locking and unlocking directions of the first latch and the second latch are the same; and the first module is provided with a first limiting part, and the second module is provided with a second limiting part;

[0010] When the first module and the second module are locked together, the first limiting part and the second limiting part abut against each other in the unlocking direction of the first locking tongue.

[0011] In one possible implementation, the movable latch further includes a locking body and an operating part and a hinge part disposed on the locking body, the hinge part being hinged to the first module; the operating part and the second latch are respectively disposed at opposite ends on the locking body, and the hinge part is located between the operating part and the second latch.

[0012] In one possible implementation, the first module has a mounting groove on its side wall, the movable latch is disposed in the mounting groove, and the outer surface of the movable latch does not protrude from the mounting groove; the operating part has a pressing protrusion, the pressing protrusion protruding from the mounting groove.

[0013] In one possible implementation, the movable latch further includes an elastic element located between the operating part and the first module.

[0014] In one possible implementation, the movable latch further includes a locking body and an operating part and a hinge part disposed on the locking body, the hinge part being hinged to the first module; the hinge part and the second latch are respectively disposed at opposite ends on the locking body, and the operating part is disposed close to the second latch.

[0015] In one possible implementation, the locking body has a hanging hole; when the movable latch is in the unlocked state, the first module can be suspended through the hanging hole.

[0016] In one possible implementation, the first latch and the second latch extend in opposite directions, with the locking and unlocking directions of the first latch and the second latch being opposite.

[0017] In one possible implementation, the movable latch further includes a locking body and an operating part and a hinge part disposed on the locking body, the hinge part being hinged to the first module; one end of the locking body away from the second latch is configured as an elastic arm structure, and the other end is connected to the second latch; the hinge part is located between the elastic arm structure and the second latch.

[0018] This utility model also provides a container stacking assembly, including a first container and a second container, wherein the first container and the second container are connected by the connection assembly described above.

[0019] The connecting component provided by this utility model allows for easy unlocking of the movable latch when the first module and the second module are locked together. This eliminates the need to unlock the latches on both sides, making it more convenient for users. Furthermore, since the first latch is fixed to the first module, its structure is simpler than that of the movable latch, which simplifies the module's structural design, facilitates assembly and manufacturing, and reduces costs.

It should be understood that the use of directional terms should not limit the scope of protection claimed by this utility model.

[0042] First Embodiment

[0043] like Figures 1 to 5 As shown, the first embodiment of this utility model provides a connecting component 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 vertically, or the first module 1 and the second module 2 are arranged to abut horizontally.

[0044] This solution is illustrated using the example of the stacked first module 1 and the second module 2.

[0045] The connection component includes:

[0046] The first locking tongue 3 and the movable latch 4 are spaced apart and opposite to each other on the first module 1; the movable latch 4 includes a second locking tongue 41, the first locking tongue 3 is fixed to the first module 1, and the second locking tongue 41 can move relative to the first module 1; the movable latch 4 has a locked state and an unlocked state; at least one locking group 5 includes a first locking part 51 and a second locking part 52 spaced apart and opposite to each other on the second module 2; when the first module 1 and the second module 2 are locked together, the first locking tongue 3 interferes with the first locking part 51, the movable latch 4 is in the locked state, and the second locking tongue 41 interferes with the second locking part 52.

[0047] In this embodiment, the first module 1 and the second module 2 can be the same size or different. The first module 1 and the second module 2 are adjacent, for example, stacked vertically or abutting each other horizontally. This connecting component can be applied to containers, such as toolboxes, tool holders, storage boxes, storage baskets, drawer boxes, wheeled boxes, tool bags, etc. It can also be applied to rigid platforms, such as flatbed carts, external panels, adapter plates, workbenches, drawing boards, etc. This connecting component is mainly used for interlocking between two modules; the first module 1 can be a container, and the second module 2 can also be a container, with the connecting component interlocking between the containers; the first module 1 / second module 2 can be containers, and the second module 2 / first module 1 can be a rigid platform, with the connecting component interlocking between the containers and the rigid platform; the first module 1 can be a rigid platform, and the second module 2 can also be a rigid platform, with the connecting component interlocking between the rigid platforms. In this embodiment, both the first module 1 and the second module 2 are containers.

[0048] like Figure 2 and Figure 6 As shown, in one embodiment, the connecting component includes multiple locking groups 5, which are disposed at different positions on the second module 2. A portion of the locking groups 5 are used for mutual locking of the first module 1 and the second module 2 of the same size, while another portion of the locking groups 5 are used for mutual locking of the first module 1 and the second module 2 of different sizes. This allows the connecting component to be compatible with the interlocking of modules of the same and different sizes. In this embodiment, the first locking portion 51 and the second locking portion 52 in a portion of the locking groups 5 are spaced apart and opposite to each other along the length direction of the second module 2, while the first locking portion 51 and the second locking portion 52 in another portion of the locking groups 5 are spaced apart and opposite to each other along the width direction of the second module 2.

[0049] like Figures 1 to 5As shown, in one embodiment, both the first latch 3 and the second latch 41 are L-shaped hook structures, extending in the same direction. The locking and unlocking directions of the first latch 3 and the second latch 41 are identical; that is, the locking direction S11 of the first latch 3 is the same as the locking direction S21 of the second latch 41, and the unlocking direction S12 of the first latch 3 is the same as the unlocking direction S22 of the second latch 41. Because the locking and unlocking directions of the first latch 3 and the second latch 41 are identical, the user can simultaneously lock / unlock the first latch 3 and the second latch 41 by moving in one direction, allowing the first module 1 and the second module 2 to lock and unlock more smoothly.

[0050] However, in the above structure, since the unlocking direction S12 of the first locking tongue 3 is the same as the unlocking direction S22 of the second locking tongue 41, the first locking tongue 3 and the second locking tongue 41 are mainly used to restrict the relative movement of the first module 1 and the second module 2 in the vertical direction. However, the first locking tongue 3 and the second locking tongue 41 alone cannot effectively restrict the relative movement of the first module 1 and the second module 2 in the horizontal direction (that is, without other horizontal limiting structures, the first module 1 can easily move relative to the second module 2 in the unlocking direction, thereby causing the locking of the first module 1 and the second module 2 to fail). Therefore, in this embodiment, the first module 1 is provided with a first limiting part 13, and the second module 2 is provided with a second limiting part 21; when the first module 1 and the second module 2 are locked together, the first limiting part 13 and the second limiting part 21 abut against each other in the unlocking direction S12 of the first locking tongue 3, thereby horizontally limiting the first module 1 and the second module 2. Furthermore, when the first limiting part 13 abuts against the second limiting part 21, the first limiting part 13 is located inside the second limiting part 21 (i.e., the first limiting part 13 is closer to the center of the first module 1 than the second limiting part 21), thereby preventing interference between the first limiting part 13 and the second limiting part 21 when the first module 1 is stacked and locked with the second module 2 along the locking direction S11.

[0051] The first locking tongue 3 and the second locking tongue 41 engage with the first locking part 51 and the second locking part 52 respectively, and the first limiting part 13 abuts against the second limiting part 21, thereby firmly locking the first module 1 and the second module 2 together.

[0052] like Figure 2 and Figure 3As shown, in one embodiment, the first module 1 has a first mounting surface 10, and the second module 2 has a second mounting surface 20. The first mounting surface 10 is located at the bottom of the first module 1, and the second mounting surface 20 is located at the top of the second module 2. The first mounting surface 10 can be placed on the second mounting surface 20. A first limiting part 13 protrudes from the first mounting surface 10, and a second limiting part 21 protrudes from the second mounting surface 20. Specifically, there are multiple first limiting parts 13 and multiple second limiting parts 21. Multiple first limiting parts 13 are spaced apart on the first mounting surface 10, and multiple second limiting parts 21 are spaced apart on the second mounting surface 20. When the first module 1 and the second module 2 are locked together, at least a portion of the first limiting part 13 can abut against at least a portion of the second limiting part 21 respectively; at the same time, the first limiting part 13 can abut against the second mounting surface 20, and / or the second limiting part 21 can abut against the first mounting surface 10. That is, in addition to serving as a horizontal limiting part, the first limiting part 13 and the second limiting part 21 can also serve as a support and positioning part for the first module 1 and the second module 2 (i.e., the first limiting part 13 and the second limiting part 21 are equivalent to support feet). The first limiting part 13 and the second limiting part 21 can specifically be block-shaped, strip-shaped, L-shaped, etc.

[0053] like Figures 2 to 5 As shown, in one embodiment, the first locking tongue 3 protrudes from the first mounting surface 10 of the first module 1, and the first locking tongue 3 is located on one side edge of the first module 1; the movable latch 4 is disposed on the opposite edge of the first module 1, and when the movable latch 4 is in the locked state, the second locking tongue 41 protrudes from the first mounting surface 10. The first latching portion 51 and the second latching portion 52 both protrude from the second mounting surface 20 of the second module 2. In other embodiments, the first locking tongue 3 and the second locking tongue 41 do not protrude from the first mounting surface 10 and the second mounting surface 20, but the first locking tongue 3 and the second locking tongue 41 may protrude from the side wall of the first module 1 and the side wall of the second module 2.

[0054] In one embodiment, the movable latch 4 is a flip latch. The movable latch 4 also includes a locking body 42 and an operating part 43 and a hinge part 44 disposed on the locking body 42. The hinge part 44 is hinged to the first module 1. The operating part 43 and the second latch 41 are respectively disposed at opposite ends of the locking body 42, and the hinge part 44 is located between the operating part 43 and the second latch 41. The operating part 43 is specifically a pressing part. The movable latch 4 also includes an elastic element 45, which is located between the operating part 43 and the first module 1. The elastic element 45 is used to automatically keep the movable latch 4 in a locked state by elastic force. In this embodiment, the elastic element 45 is a spring, and its two ends abut against the operating part 43 and the first module 1 respectively; of course, in other embodiments, the elastic element 45 can also be a V-shaped spring or other structure.

[0055] When the first module 1 and the second module 2 are stacked and interlocked, the side of the first module 1 closest to the first latch 3 is first tilted to contact the second module 2, so that the first latch 3 is tilted to engage with the first locking part 51. The edge of the first module 1 closest to the first latch 3 is provided with a relief groove 12, which is used to avoid the first locking part 51, so as to reduce or avoid interference between the first module 1 and the first locking part 51. After the first latch 3 is engaged with the first locking part 51, the other side of the first module 1 is lowered. The second latch 41 flips outward under the stop action of the second locking part 52, while the elastic element 45 is compressed and stored. After the first module 1 is pressed down, the second latch 41 flips inward under the elastic force of the elastic element 45, so that the second latch 41 engages with the second locking part 52, thereby realizing the interlocking of the first module 1 and the second module 2.

[0056] When unlocking the first module 1 and the second module 2, the operating part 43 is pressed inward (i.e. towards the center of the first module 1) to cause the second locking tongue 41 to flip outward, at which point the second locking tongue 41 disengages from the second locking part 52; then the first module 1 is moved diagonally upward to disengage the first locking tongue 3 from the first locking part 51, thus unlocking the first module 1 and the second module 2.

[0057] like Figures 2 to 5 As shown, in one embodiment, the first module 1 has a mounting groove 11 on its side wall, and the movable latch 4 is disposed in the mounting groove 11. The outer surface of the movable latch 4 does not protrude from the mounting groove 11 (that is, the outer surface of the movable latch 4 does not protrude from the side wall of the first module 1 near the mounting groove 11), so that the movable latch is located in the mounting groove 11 when locked, and is protected from external damage. The operating part 43 is provided with a pressing protrusion 431, which protrudes from the mounting groove 11 (that is, the pressing protrusion 431 protrudes from the side wall of the first module 1 near the mounting groove 11). The pressing protrusion 431 can play a role in preventing slippage and reducing the unlocking stroke of the operating part 43. Figures 1 to 5 and Figure 18 and Figure 19 As shown, during unlocking, the user can press the pressing protrusion 431 with their hand, causing the operating part 43 to flip inward and the second locking tongue 41 to flip outward (i.e., away from the center of the first module 1); simultaneously, an outward pulling force is applied to the first module 1 (when an outward pulling force is applied to the first module 1, it can be done as follows). Figure 18 As shown, you can also hold the structural component on the first module 1 with your fingers, as shown. Figure 19 As shown, pinch the side wall of the first module 1 with your fingers to facilitate applying force, so that the first module 1 separates from the second module 2 outward, thus facilitating one-handed operation.

[0058] like Figure 2 and Figure 3As shown, in one embodiment, since the first module 1 is stacked and interlocked with the second module 2 by oblique insertion, a guide strip 14 is also provided on the first mounting surface 10 of the first module 1. The guide strip 14 can play a guiding role when the first module 1 is inserted obliquely, preventing the first module 1 from shifting and correcting the insertion direction of the first module 1. At the same time, when the first module 1 and the second module 2 are locked together, the guide strip 14 can also abut against some of the second limiting parts 21 on the second module 2 to play a horizontal limiting role.

[0059] like Figures 2 to 5 As shown, in one embodiment, the inner walls of the mounting groove 11 on opposite sides are provided with rotating holes 15. The hinge part 44 includes protrusions 441 disposed on opposite sides of the locking body 42. The protrusions 441 on opposite sides are respectively located in the rotating holes 15 on opposite sides, and the protrusions 441 can rotate within the rotating holes 15, thereby realizing the hinge between the movable latch 4 and the first module 1. At the same time, the inner wall of the mounting groove 11 is provided with a notch 151 corresponding to the position of the rotating hole 15. The protrusions 441 are provided with a non-straight surface 440, which can be a slope or an arc surface, etc. When the protrusions 441 are installed into the rotating holes 15, the non-straight surface 440 on the protrusions 441 can easily pass through the notch 151, thereby facilitating assembly.

[0060] like Figure 4 and Figure 5 As shown, in one embodiment, the inner wall of the mounting groove 11 is provided with a limiting groove 16, the inner wall of the operating part 43 is provided with a limiting post 46, one end of the elastic member 45 is located in the limiting groove 16, and the other end of the elastic member 45 is sleeved on the limiting post 46, thereby limiting the elastic member 45.

[0061] like Figure 6 As shown, this embodiment of the present invention also provides a container stacking assembly, including at least one first container and at least one second container. The first container and the second container are connected by the aforementioned connecting assembly, that is, 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 the same size or different size (the size of the first module 1 may be larger or smaller than the second module 2).

[0062] The connection component provided in this embodiment allows for easy unlocking of the movable latch 4 when the first module 1 and the second module 2 are locked together. This eliminates the need to unlock the latches on both sides, making it more convenient for users. Furthermore, since the first latch 3 is fixed to the first module 1, its structure is simpler than that of the movable latch, which simplifies the structural design of the module, facilitates assembly and manufacturing, and reduces costs.

[0063] Second Embodiment

[0064] like Figure 7 and Figure 8 As shown, the connecting component of the second embodiment of this utility model has a basically the same structure as the connecting component of the first embodiment. The main difference is that the assembly method of the movable latch 4 and the first module 1 is different (the elastic element 45 is not shown in the figure).

[0065] Specifically, in this embodiment, the connecting assembly further includes a mounting base 6, and the hinge portion 44 is a rotating shaft 442 connected to the locking body 42, with the rotating shaft 442 rotatably connected to the mounting base 6. Specifically, the mounting base 6 has rotating shaft holes 62 on opposite sides, and both ends of the rotating shaft 442 extend to opposite sides of the locking body 42, with both ends located within the rotating shaft holes 62 on opposite sides. The side wall of the first module 1 has a mounting groove 11, and the mounting base 6 is located within the mounting groove 11 and fixed to the first module 1.

[0066] In this embodiment, the mounting base 6 is snapped into and fixed to the first module 1. Specifically, the mounting base 6 has snap-fit ​​blocks 61 on opposite sides, and the mounting groove 11 has snap-fit ​​slots 17 on opposite sides. The snap-fit ​​blocks 61 on opposite sides are respectively snapped into the snap-fit ​​slots 17 on opposite sides, thereby realizing the snap-fit ​​and fixing of the mounting base 6 and the first module 1.

[0067] During assembly, first assemble the rotating shaft 442 with the locking body 42, then install the rotating shaft 442 onto the mounting base 6, and then install the mounting base 6 into the mounting slot 11 of the first module 1. For replacement, only the mounting base 6 needs to be replaced.

[0068] Other structures and functions in this embodiment are the same as or similar to those in the first embodiment, and will not be described in detail here.

[0069] Third Embodiment

[0070] like Figures 9 to 13 As shown, the connecting component of the third embodiment of this utility model has a basically the same structure as the connecting component of the first embodiment, the main difference being the structure of the movable latch 4.

[0071] Specifically, in this embodiment, the movable latch 4 is also a flip latch, but no elastic element is provided in the movable latch 4. The movable latch 4 includes a locking body 42 and an operating part 43, a hinge part 44, and a second latch 41 disposed on the locking body 42. The hinge part 44 is hinged to the first module 1. The hinge part 44 and the second latch 41 are respectively disposed at opposite ends on the locking body 42, and the operating part 43 is disposed close to the second latch 41. The operating part 43 is specifically a handle.

[0072] When the first module 1 and the second module 2 are stacked and interlocked, the operating part 43 needs to be activated first to flip the movable latch 4 outward and open it. After the first latch 3 and the first locking part 51 are inserted into place and the first module 1 is placed on the second module 2, the movable latch 4 is flipped inward to engage the second latch 41 and the second locking part 52, thereby realizing the interlocking of the first module 1 and the second module 2.

[0073] When unlocking the first module 1 and the second module 2, first pull the operating part 43 to flip the movable latch 4 outward and open it, so that the second latch 41 disengages from the second locking part 52; then move the first module 1 diagonally upward so that the first latch 3 disengages from the first locking part 51, thus unlocking the first module 1 and the second module 2.

[0074] In this embodiment, the first locking tongue 3 and the second locking tongue 41 extend in the same direction. The locking direction and unlocking direction of the first locking tongue 3 and the second locking tongue 41 are the same. In order to prevent the locking of the first module 1 and the second module 2 from failing, this embodiment also needs to set the first limiting part 13 and the second limiting part 21 to horizontally limit the first module 1 and the second module 2.

[0075] In this embodiment, the hinge part 44 is a rotating shaft 442 connected to one end of the locking body 42, that is, one end of the locking body 42 is hinged to the first module 1 through the rotating shaft 442.

[0076] like Figure 12 and Figure 13 As shown, in this embodiment, the locking body 42 has a hanging hole 420 located between the hinge portion 44 and the second locking tongue 41. When the movable latch 4 is in the unlocked state, the first module 1 can be suspended to a designated position through the hanging hole 420. In other embodiments, the latch 420 can also be used as the handle of the operating part 43.

[0077] Other structures and functions in this embodiment are the same as or similar to those in the first embodiment, and will not be described in detail here.

[0078] Fourth embodiment

[0079] like Figures 14 to 17 As shown, the connecting component of the fourth embodiment of this utility model has a basically the same structure as the connecting component of the first embodiment, the main difference being the structure of the movable latch 4.

[0080] Specifically, in this embodiment, the movable latch 4 is an elastic latch, but no elastic element is provided in the movable latch 4; the movable latch 4 itself is elastic. The movable latch 4 includes a locking body 42 and an operating part 43, a hinge part 44, and a second latch 41 disposed on the locking body 42. The locking body 42 is an elastic structure, and the locking body 42 can be made of elastic materials such as plastic. The hinge part 44 is hinged to the first module 1; one end of the locking body 42 away from the second latch 41 is set as a suspended elastic arm structure 48, and the other end is connected to the second latch 41. The operating part 43 is a handle, and the operating part 43 is disposed close to the second latch 41.

[0081] When the first module 1 and the second module 2 are stacked and interlocked, the side of the second module 2 closest to the first latching part 51 is first tilted to contact the first module 1, so that the first latching part 51 is tilted to engage with the first locking tongue 3. After the first latching part 51 and the first locking tongue 3 are engaged, the other side of the second module 2 is lowered and pressed down. The second locking tongue 41 flips outward under the stop action of the second latching part 52. The end of the locking body 42 away from the second locking tongue 41 (i.e., the elastic arm structure 48) abuts against the first module 1 and undergoes elastic deformation. After the first module 1 is pressed down into place, the second locking tongue 41 flips inward under the elastic force of the elastic arm structure 48, so that the second locking tongue 41 engages with the second latching part 52, thereby realizing the interlocking of the first module 1 and the second module 2.

[0082] When unlocking the first module 1 and the second module 2, the operating part 43 is pulled to make the movable latch 4 flip outward, so that the second latch 41 disengages from the second locking part 52; then the first module 1 is moved diagonally upward, so that the first latch 3 disengages from the first locking part 51, thus unlocking the first module 1 and the second module 2.

[0083] In this embodiment, the first locking tongue 3 and the second locking tongue 41 extend in opposite directions, and the locking and unlocking directions of the first locking tongue 3 and the second locking tongue 41 are opposite; that is, the locking direction S11 of the first locking tongue 3 is opposite to the locking direction S21 of the second locking tongue 41, and the unlocking direction S12 of the first locking tongue 3 is opposite to the unlocking direction S22 of the second locking tongue 41. Although this embodiment also provides a first limiting part 13 and a second limiting part 21, compared with the first to third embodiments, since the unlocking directions of the first locking tongue 3 and the second locking tongue 41 are opposite in this embodiment, the first locking tongue 3 and the second locking tongue 41 can already play a better horizontal limiting role for the first module 1 and the second module 2. Therefore, this embodiment relies less on the horizontal limiting function of the first limiting part 13 and the second limiting part 21, and the first limiting part 13 and the second limiting part 21 mainly play a positioning role when stacked.

[0084] In this embodiment, the hinge portion 44 is connected to the first module 1 by a snap-fit ​​connection. Specifically, the hinge portion 44 includes a first snap-fit ​​structure 47 disposed on the inner sidewall of the locking body 42; the sidewall of the first module 1 is provided with a mounting groove 11, the inner wall of the mounting groove 11 is provided with a second snap-fit ​​structure 18, the movable latch 4 is located in the mounting groove 11, the first snap-fit ​​structure 47 and the second snap-fit ​​structure 18 of the hinge portion 44 are connected by a snap-fit ​​connection, and the first snap-fit ​​structure 47 can rotate slightly relative to the second snap-fit ​​structure 18, so that the movable latch 4 can flip within the mounting groove 11.

[0085] Other structures and functions in this embodiment are the same as or similar to those in the first embodiment, and will not be described in detail here.

[0086] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
