[0037] The directional words such as up, down, left, right, front, back, top, bottom, etc. (if any) involved in the specification and claims of the utility model are defined by the positions of the structures in the drawings and the positions of the structures relative to each other, and are only for the clarity and convenience of expressing the technical solution. It should be understood that the use of directional words should not limit the scope of protection claimed by the utility model.

[0038] like Figures 1 to 9 As shown, this embodiment provides a connection assembly for connecting a first module and a second module, and the connection assembly includes a locking rod structure 2 and a locking structure 3 that can be mutually locked with the locking rod structure 2. Specifically, the locking rod structure 2 includes a front locking portion and a rear locking portion arranged on the mounting surface of the first module, and the front locking portion and the rear locking portion can be in a groove shape, a through hole shape, or a rod shape; in this embodiment, the front locking portion is a front locking rod 21, and the rear locking portion is a rear locking rod 22, both of which are rod-shaped.

[0039] The front locking rod 21 and the rear locking rod 22 are arranged in parallel with each other and protrude from the mounting surface of the first module. The locking structure 3 includes a front locking tongue 31, a rear locking tongue 32 and a lock catch 33 arranged on one side surface of the second module. The front locking tongue 31 and the rear locking tongue 32 are arranged in parallel with each other, and the lock catch 33 has a locked state and an unlocked state. When the rear locking tongue 32 interferes with the rear locking rod 22 and the lock catch 33 interferes with the front locking rod 21, the first module and the second module are locked with each other.

[0040] like Figure 2 , Figure 3 , Figure 8 and Fig. 9As shown, as an embodiment, the front lock tongue 31 may also interfere with the front lock rod 21, and the front lock tongue 31 and the rear lock tongue 32 extend in the same direction, thereby further stably locking the first module and the second module. The front lock tongue 31 and the rear lock tongue 32 are both arranged on the mounting surface 120 of the second module, and a stop space 30 is formed between the front lock tongue 31, the rear lock tongue 32 and the mounting surface 120 on the second module. When the first module and the second module are locked with each other, the front lock rod 21 and the rear lock rod 22 are both located in the stop space 30. The lock buckle 33 includes a locking member 331 and an operating member 332 connected to the locking member 331 in a transmission manner; when the first module and the second module are locked with each other, the locking member 331 is located on the side of the front lock rod 21 away from the front lock tongue 31.

[0041] Specifically, in this embodiment, the front lock tongue 31 and the rear lock tongue 32 are both L-shaped structures, and the opening directions of the front lock tongue 31 and the rear lock tongue 32 are the same, and the stop space 30 is a slot formed between the front lock tongue 31, the rear lock tongue 32 and the mounting surface 120 on the second module. The operating member 332 is a buckle hand portion provided on the locking member 331 (of course, in other embodiments, the operating member 332 can also be other structures). When the first module and the second module are locked, the front lock tongue 31 and the rear lock tongue 32 are respectively engaged with the front lock rod 21 and the rear lock rod 22 to limit the up and down and front and back movement of the first module and the second module; at the same time, the locking member 331 abuts against the side of the front lock rod 21 away from the front lock tongue 31, thereby limiting the front and back movement of the first module and the second module, and realizing the stacking interlocking between the two modules. When the first module and the second module need to be separated, it is only necessary to pull the operating member 332 to move the locking member 331 upward and release the lock from the front locking rod 21, and then the first module and the second module can be separated.

[0042] like Figure 3 , Figure 5 and Fig. 9As shown, as an embodiment, the lock buckle 33 is an up and down sliding lock buckle, and the lock buckle 33 also includes an elastic member 333, and the elastic member 333 is located between the locking member 331 and the second module (of course, in other embodiments, the elastic member 333 can also be arranged between the operating member 332 and the second module), and the elastic member 333 is used to drive the locking member 331 to extend downward so that the locking member 331 is automatically kept in a locked state. At the same time, a non-straight surface 331A is provided on the side of the locking piece 331 away from the front lock tongue 31 (i.e., toward the locking direction), and the non-straight surface 331A is specifically an inclined surface (of course, the non-straight surface 331A can also be a curved surface or other structures); when the first module approaches the second module along the locking direction, the non-straight surface 331A on the locking piece 331 contacts the front lock rod 21, so that the locking piece 331 automatically moves upward under the squeezing action of the front lock rod 21, and the elastic piece 333 accumulates force at this time; after the locking piece 331 passes over the front lock rod 21, the locking piece 331 automatically moves downward under the elastic force of the elastic piece 333, so that the locking piece 331 and the side of the front lock rod 21 away from the front lock tongue 31 (i.e., toward the locking direction) are abutted against each other, thereby realizing automatic locking of the first module and the second module.

[0043] As an implementation manner, the front locking rod 21 and the rear locking rod 22 are both steel wires.

[0044] This embodiment also provides a container 1, which is locked with another container 1 through a connecting assembly, so as to facilitate the transportation and storage of multiple containers 1, that is, the first module and the second module are both containers 1. The container 1 can be a storage box, which can be a storage device such as a tool box, a storage box, a transport box, a transfer box, etc.

[0045] like Figures 1 to 3 As shown, as an embodiment, the container 1 includes a box body 12 and a box cover 11, and the box cover 11 is located above the box body 12. The locking rod structure 2 is arranged at the top of the container 1. One side of the box body 12 is rotatably connected with one side of the box cover 11 through a first hinge, and the first hinge is a rear locking rod 22. The other side of the box body 12 is locked with the other side of the box cover 11 through a latch 13, and the latch 13 is rotatably connected with the box cover 11 through a second hinge, and the second hinge is a front locking rod 21; that is, the front locking rod 21 and the rear locking rod 22 are respectively located on opposite sides of the box cover 11. The locking structure 3 is arranged at the bottom of the box body 12, the front locking tongue 31 and the lock buckle 33 are arranged on one side of the bottom of the box body 12, and the rear locking tongue 32 is arranged on the other side of the bottom of the box body 12, so that any two containers 1 can be stacked up and down and locked with each other.

[0046] Specifically, the latch 13 is a rotating lock, and the box body 12 is provided with a locking portion 121 that can be engaged and locked with the latch 13; by rotating the latch 13, the latch 13 and the locking portion 121 can be engaged and locked or unlocked, thereby achieving the locking and unlocking between the box cover 11 and the box body 12. When in use, by opening the latch 13, the latch 13 and the locking portion 121 are unlocked, and then the box cover 11 can be rotated relative to the box body 12 to open. Since the front locking rod 21 and the rear locking rod 22 have the function of a rotating shaft and can also serve as an engaging mechanism (the front locking rod 21 and the rear locking rod 22 are the original structures on the container 1), that is, the locking rod structure 2 can achieve dual purposes, thereby simplifying the structural design of the container 1.
