[0031] like Figure 1 As shown, the present application discloses an interlocking structure of a stacking container. In this embodiment, the container is specifically a tool box, specifically including a first tool box 100 and a second tool box 200, the second tool box 200 can be stacked on the first tool box 100, and the interlocking structure is used to lock the first tool box 100 and the second tool box 200 to each other.

[0032] Specific, combined Figure 1 , 5 As shown in Figure 7, the first tool box 100 includes a first base 11, a first upper cover 12 and an interlocking assembly 13. The first base 11 is hingedly connected to the first upper cover 12. The interlocking assembly 13 is mounted to the first upper cover 12. The second tool box 200 includes a second base 21 and a second upper cover 22. The second base 21 is hingedly connected to the second upper cover 22. The second base 21 is provided with a locking groove 211.

[0033] In this embodiment, the interlocking assembly 13 includes a rotating block 131, an active buckle 132, and an elastic member 133. The elastic member 133 is disposed between the active buckle 132 and the side wall 122 of the first upper cover 12. The active buckle 132 has a hook 1321 protruding from the first upper cover 12. The rotating block 131 is disposed on the outer side of the active buckle 132. The rotating block 131 is used to drive the active buckle 132 to move so that the hook 1321 of the active buckle 132 can cooperate with the locking groove 211.

[0034] The interlocking assembly 13 includes a locked state and an unlocked state. When the interlocking assembly 13 is in the locked state, the movable buckle 132 is in the first position, and the elastic member 133 is in the natural state. At this time, the hook 1321 of the first tool box 100 can engage the locking groove 211 of the second tool box 200, so that the second tool box 200 is locked to the first tool box 100.

[0035] When the interlocking assembly 13 is in the unlocked state, the movable buckle 132 is in the second position, and the elastic member 133 is deformed. At this time, the hook 1321 of the first tool box 100 can be disengaged from the locking groove 211 of the second tool box 200, so that the second tool box 200 can be disassembled from the first tool box 100.

[0036] Rotating the rotating block 131 can switch the interlocking assembly 13 from the locked state to the unlocked state; the elastic member 133 can automatically switch the interlocking assembly 13 from the unlocked state to the locked state under the force of elastic deformation.

[0037] In this embodiment, the user can switch the state of the interlocking assembly 13 by rotating the rotating block 131. The interlocking structure does not require precise matching clearance and does not require high structural accuracy, thereby reducing manufacturing difficulty and improving production efficiency. At the same time, the user can avoid the problem of jamming during operation, and the user experience is better.

[0038] Specifically, in this embodiment, if Figure 2 As shown, the first upper cover 12 of the first tool box 100 includes a top wall 121 and surrounding side walls 122, wherein an inner wall 123 is further disposed within one of the side walls 122, and generally, the side wall 122 is a short side wall 122. A cavity is formed between the side wall 122 and the inner wall 123, and the movable buckle 132 is accommodated in the cavity. The side wall 122 is provided with a through hole 1231, and the through hole 1231 is connected to the cavity. The top wall 121 is provided with a track groove 1210, and the track groove 1210 is also connected to the cavity.

[0039] Combination Figure 3As shown, a plurality of slots are provided on the side edge of the rotating block 131, specifically, four slots 1313, 1314, 1315, 1316 are evenly provided around the edge of the rotating block 131. The rotating block 131 is fixed on the surrounding walls of the through hole 1231 formed in the side wall 122 through the slots 1313, 1314, 1315, 1316, so that the rotating block 131 is movably mounted to the first upper cover 12.

[0040] A knob 1312 is provided on one side of the rotating block 131, and a mounting groove 1317 and a boss 1311 are provided on the other side. The knob 1312 exposes the through hole 1231 of the side wall 122 so that the user can drive the rotating block 131. The mounting groove 1317 and the boss 1311 face the movable buckle 132, and extend into the cavity through the through hole 1231 of the side wall 122 to cooperate with the movable buckle 132. The mounting groove 1317 is provided at the center of the back side of the rotating block 131. The rotating block 131 has two bosses 1311, which are respectively provided on both sides of the mounting groove 1317. The boss 1311 also has an inclined surface 1311a.

[0041] Combination Figure 4 As shown, the movable buckle 132 has a body extending in the longitudinal direction and a guide plate 1324 extending in the transverse direction. The body is disposed in the cavity of the first upper cover 12. A hook 1321 is formed at the top of the body, and the hook 1321 protrudes from the guide plate 1324, extends from the track groove 1210 of the first upper cover 12, and protrudes from the top wall 121 of the first upper cover 12. A mounting column 1323 is disposed on one side of the body facing the rotating block 131, and the mounting column 1323 protrudes toward the rotating block 131. The mounting column 1323 can be inserted into the mounting groove 1317 of the rotating block 131, so that the rotating block 131 can be rotatably mounted to the movable buckle 132.

[0042] The movable buckle 132 further includes a plurality of protrusions 1322 arranged at intervals, and the protrusions 1322 are evenly distributed around the mounting column 1323. The protrusions 1322 of the movable buckle 132 are arranged opposite to the boss 1311 of the rotating block 131. Preferably, the movable buckle 132 has four protrusions 1322, and the mounting column 1323 is arranged in the middle of the protrusions 1322. When the interlocking assembly 13 is in the locked state, the boss 1311 of the rotating block 131 is located between the two protrusions 1322, and the boss 1311 does not interfere with the protrusion 1322.

[0043] Combination Figure 2 and 5 As shown, the guide plate 1324 is parallel to the top wall 121 of the first upper cover 12, and the guide plate 1324 is received in the track groove 1210 of the first upper cover 12 and can move in the track groove 1210 of the first upper cover 12, that is, the movable buckle 132 can move laterally.

[0044] like Figure 7 As shown, one end of the elastic member 133 abuts against the body of the movable buckle 132, and the other end abuts against the inner wall 123 of the first upper cover 12. Preferably, the mounting post 1323 of the movable buckle 132 is hollow inside, and the elastic member 133 can be accommodated in the hollow mounting post 1323. In the figure, the elastic member 133 can be elastically deformed in the lateral direction. In this embodiment, the elastic member 133 is specifically a spring.

[0045] Combination Figure 2 and 6 As shown, the first upper cover 12 of the first tool box 100 is further provided with a second hook 124. The second base 21 of the second tool box 200 is further provided with a second locking groove 212, and the second hook 124 is engaged with the second locking groove 212.

[0046] Combination Figure 7 As shown, the interlocking structure of the stacking tool box works as follows:

[0047] The interlocking assembly 13 in the first tool box 100 is in a locked state, the movable buckle 132 is in the first position, and the boss 1311 of the rotating block 131 is located between the two protrusions 1322 of the movable buckle 132. At this time, the rotating block 131 is in a locked position. When the second tool box 200 needs to be stacked and locked to the first tool box 100, the user places the second tool box 200 on top of the first tool box 100, and first clamps the second hook 124 of the first tool box 100 into the second locking groove 212 of the second tool box 200. Then, the hook 1321 of the movable buckle 132 in the first tool box 100 is directly clamped into the locking groove 211 of the second tool box 200 to achieve mutual locking of the first tool box 100 and the second tool box 200.

[0048] When the second tool box 200 needs to be separated from the first tool box 100, the user turns the knob 1312 on the first tool box 100 to rotate the rotating block 131 of the first tool box 100. The boss 1311 of the rotating block 131 interferes with the protrusion 1322 of the movable buckle 132, and the inclined surface 1311a of the boss 1311 plays a guiding role, which facilitates the boss 1311 to pass over the protrusion 1322. The boss 1311 of the rotating block 131 presses on the protrusion 1322 of the movable buckle 132, and at this time, the rotating block 131 is in the unlocking gear. The protrusion 1322 of the movable buckle 132 is pressed by the boss 1311 of the rotating block 131, and the movable buckle 132 moves to the second position in the direction toward the inner wall 123 in the horizontal direction. The guide plate 1324 of the movable buckle 132 moves along the track groove 1210 to play a guiding role, which helps the movable buckle 132 to move smoothly. The movable buckle 132 moves toward the inner wall 123 to compress the spring, causing the spring to deform. At this time, the interlocking component 13 is in an unlocked state. When the movable buckle 132 is in the second position, its hook 1321 is away from the lock groove 211 of the second tool box 200, and the user can remove the second tool box 200 from the first tool box 100.

[0049] When the user releases the knob 1312 of the rotating block 131, the movable buckle 132 also loses the pressure of the rotating block 131, and the spring also loses the pressure of the movable buckle 132. Therefore, the spring returns to its original state, and under the action of elastic deformation, it pushes the movable buckle 132 to move away from the inner wall 123, that is, from the second position to the first position, and the interlocking assembly 13 automatically switches from the unlocked state to the locked state.

[0050] In this embodiment, the mutual locking and disassembly between the two tool boxes is achieved by rotating the rotating block 131. The movement of the interlocking structure is more stable. When in use, the rotating block 131 has two gears of locking and unlocking. It is more convenient to use it alone.

[0051] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Although the present application has been disclosed as a preferred embodiment as above, it is not intended to limit the present application. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present application. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application still falls within the scope of the technical solution of the present application.
