Background Technology
[0002] In storage and organization scenarios, items are typically placed together in containers. To further improve space utilization and facilitate the classification, management, and transportation of items, multiple containers are stacked together to form container assemblies. For example, in the use of tool storage boxes, multiple tool storage boxes are stacked to centrally classify and manage tools. However, during the stacking of multiple containers, the lack of constraints between adjacent containers can easily lead to wobbling, resulting in a lack of structural stability for the overall container assembly.
[0003] To further improve the stability of container assembly placement, existing technologies incorporate constraint structures at the top and bottom of the containers. This ensures that when adjacent containers are stacked, the bottom of the upper container interlocks with the top of the lower container, thus reducing horizontal misalignment between layers. However, in practical use, these constraint structures can sometimes result in adjacent containers becoming completely jammed, making separation difficult. This significantly increases the difficulty for users to separate the container assemblies, sometimes requiring two people to stack and disassemble them simultaneously, thus lacking ease of use.

DETAILED DESCRIPTION
[0024] The specific embodiments of the utility model will be described in detail below with reference to the drawings.
[0025] As Figures 1-7 shown in the utility model embodiment, a coupling mechanism for container assembly is provided, which aims to improve the stability of the container assembly, reduce the difficulty of stacking and disassembling between adjacent containers, and improve the convenience of use.
[0026] The coupling mechanism for container assembly provided in the utility model embodiment realizes the convenient attachment and disassembly between containers through the design of the flip buckle and the buckle groove. Only simple manual operation is needed to quickly attach or release the first container and the second container. The operation process does not need to rely on additional tools, which improves the convenience and efficiency of use. The sliding knob in the sliding unlocking assembly makes the operation of unlocking simple and intuitive. Only by sliding the sliding knob gently can the flip buckle be separated from the buckle groove, realizing the quick separation between containers. In addition, the end of the sliding knob is locked in the locking groove on the sliding inclined surface, so that the sliding knob is automatically kept in the open state after the operation is completed, preventing misoperation, improving the stability of the container assembly, reducing the difficulty of stacking and disassembling between adjacent containers, and improving the convenience of use.
[0027] As Figure 1 shown in combination Figure 2 with, a coupling mechanism 3 for container assembly is used to detachably attach a first container 1 on a second container 2. The coupling mechanism 3 includes a first coupling piece 31 located on the first container 1, and a second coupling piece 32 located on the second container 2.
[0028] As Figure 3 shown in combination Figure 5 with, the first coupling piece 31 includes a buckle groove 311 for cooperating with the second coupling piece 32 to form a buckling. The buckle groove 311 is provided with an inclined block 312. The inclined block 312 is provided with a sliding inclined surface 313. The end of the sliding inclined surface 313 is provided with a locking groove 314.
[0029] As Figure 4 shown in combination Figure 5As shown, the second coupling member 32 comprises a flip buckle 321 and a sliding unlocking assembly 322. The flip buckle 321 is used to be buckled in the buckle slot 311, so that the first container 1 and the second container 2 form an attachment. The sliding unlocking assembly 322 is used to make the flip buckle 321 disengage from the buckle slot 311, releasing the first container 1 and the second container 2 forming an attachment.
[0030] As shown, Figure 6 In combination Figure 7 As shown, the sliding unlocking assembly 322 is provided with a sliding knob 3221. The sliding knob 3221 is installed on the flip buckle 321. The sliding knob 3221 slides along a direction parallel to the rotation axis of the flip buckle 321. The sliding knob 3221 is provided with a top block 3222 for contacting the sliding inclined surface 313.
[0031] As shown, Figure 7 As shown, the flip buckle 321 comprises a flip plate 3211, a rotating shaft 3212 and a first reset spring 3213. The flip plate 3211 is connected to the second container 2 through the rotating shaft 3212. The first reset spring 3213 is installed at the end of the rotating shaft 3212. For example, the first reset spring 3213 is a torsion spring. In this way, by providing the first reset spring 3213 (such as a torsion spring) in the flip buckle 321, the flip plate 3211 can automatically reset after completing the attachment or unlocking operation, reducing the operation steps of the user, improving the operation efficiency, especially in the case of frequent use, the automatic reset function of the flip plate 3211 significantly improves the convenience.
[0032] Among them, the application of the torsion spring makes the flip plate 3211 always remain in the preset position when not subjected to external force, preventing accidental unlocking caused by external force or vibration, and further improving the safety of the operation, especially in the process of transportation or storage, which can effectively prevent the containers from being accidentally detached.
[0033] As shown, Figure 6 In combination Figure 7 As shown, the flip plate 3211 is provided with a guide strip 3214, which is arranged along the sliding direction of the sliding knob 3221. The sliding knob 3221 is provided with a clamping groove 3223 for matching the guide strip 3214. The guide strip 3214 is used to ensure that the sliding knob 3221 runs along the predetermined track during sliding, effectively preventing the sliding knob 3221 from deviating due to external force or improper operation, improving the stability and reliability of the unlocking operation. The guide strip 3214 provides a clear sliding path for the sliding knob 3221, so that the sliding knob 3221 can always remain on the correct track during sliding, thereby improving the accuracy and efficiency of the operation when the user does not need to pay too much attention to the position of the sliding knob 3221.
[0034] In addition, the guide bar 3214 restricts the sliding direction and range of the slider 3221, preventing accidental operation. For example, if the user accidentally pushes the slider 3221, the slider 3221 will not deviate from the predetermined trajectory due to the restriction of the guide bar 3214, thus avoiding accidental unlocking or attachment failure.
[0035] like Figure 6 Combination Figure 7 As shown, the sliding unlock assembly 322 also includes a second return spring 3224. The second return spring 3224 is located between the slider 3221 and the flip plate 3211. The second return spring 3224 is arranged along the sliding direction of the slider 3221. For example, the second return spring 3224 is a compression spring. In this way, the second return spring 3224 (compression spring) allows the slider 3221 to automatically return to its initial position after the unlocking operation is completed, reducing the steps required for the user to manually reset the slider 3221, improving operational efficiency and ease of use. Furthermore, the compression spring provides a linear reaction force during the sliding of the slider 3221, making the sliding operation smoother and more stable. When the user applies force to slide the slider 3221, they can feel the elastic feedback of the spring, making the operating experience more comfortable.
[0036] When the connecting mechanism 3 for container components proposed in this embodiment of the present invention is used, such as... Figure 1 As shown, the first container 1 is pressed downwards from above the second container 2, with the bottom edge of the first container 1 contacting the flip-fastener 321 on the second container 2. The flip-fastener 321 on the second container 2 first flips outwards, allowing the first container 1 to be smoothly placed on top of the second container 2. Subsequently, the flip-fastener 321 flips inwards, engaging with the latch 311 on the first container 1, thus attaching the first container 1 to the second container 2 and completing the stacking lock between the first container 1 and the second container 2.
[0037] During the disassembly and detachment of the first container 1 and the second container 2, the sliding button 3221 in the sliding unlocking assembly 322 disengages the flip-hook 321 from the latch slot 311. The sliding button 3221 is manually slid along a direction parallel to the axis of rotation of the flip-hook 321. During this sliding, the top block 3222 slides on the sliding ramp 313. Under the action of the sliding ramp 313, the sliding button 3221 is pushed outwards towards the second container 2, thereby causing the flip-hook 321 to flip outwards towards the second container 2, disengaging it from the latch slot 311. The sliding button 3221 slides until its top block 3222 falls into the locking groove 314 of the ramp 312, restricting the sliding button 3221 from entering the sliding ramp 313, and the flip-hook 321 remains open. The first container 1 is then lifted, completing the disassembly of the attached first container 1 and second container 2.
[0038] For example, the coupling mechanism 3 is used to detachably attach two toolboxes, when the two toolboxes need to be connected, the bottom of the upper toolbox needs to be pressed onto the cover of the lower toolbox, the bottom of the upper toolbox is designed with an inclined surface in contact with the flip buckle 321, and the flip buckle 321 is provided with a matching inclined surface. The flip buckle 321 will rotate and open under the force. After the bottom of the upper toolbox is installed in place, the flip buckle 321 is automatically reset under the action of the torsion spring, the flip buckle 321 is flipped towards the inside of the lower toolbox, and the buckle slot 311 of the upper toolbox is formed. The connection process of the two toolboxes is completed.
[0039] When the upper toolbox needs to be taken out, slide the slide button 3221 on the cover of the lower toolbox, the slide button 3221 slides in the sliding process, the top block 3222 slides on the inclined surface of the bottom, and the slide button 3221 is driven outward under the action of the inclined surface. At the same time, the buckle is rotated and opened, when it is opened to a certain angle, the top block 3222 of the slide button 3221 falls into the locking groove 314 of the bottom, the slide button 3221 is blocked, and the buckle will remain open at this time. At this time, the upper toolbox can be taken out. After the upper toolbox is taken out, the locking groove 314 of the bottom that stops the slide button 3221 is removed, the slide button 3221 is reset under the action of the compression spring, and the knob is reset under the action of the torsion spring, which is convenient for connecting the toolboxes next time.
[0040] The utility model embodiment further proposes a container assembly, comprising at least one first container 1 and at least one second container 2, and comprising the coupling mechanism 3 for the container assembly, and the first container 1 and the second container 2 are detachably attached through the coupling mechanism 3.
[0041] For example, as shown in the drawings, Figure 3 The bottom of the first container 1 is provided with a first coupling piece 31, and the top of the first container 1 is provided with a second coupling piece 32. The top of the second container 2 is provided with a second coupling piece 32.
[0042] Among them, the container assembly is intended to represent a plurality of containers combined in any shape and size, such as storage containers, travel luggage, toolboxes, and any container can be detachably attached to any other container.
