Example (b): as shown in fig. 1 to 3, this embodiment provides an interlocking mechanism for a container, which is used to lock a plurality of containers 3 stacked one above another, and includes a lock body 1 and a position retaining mechanism 2, wherein the lock body 1 is slidably assembled at two ends of each container 3, and the lock bodies 1 at two ends of the containers 3 are vertically corresponding to each other, the lower portions of two sides of each lock body 1 are respectively provided with a slot 11 having two ends penetrating through the lower portion, two sides of the lower end of the lock body 1 on all containers 3 except the lowermost layer are respectively hinged with a hook assembly 12, under an external force, the lock body 1 at two ends of each layer of the container 3 is pushed upward, and at the same time, the lock body 1 drives the hook assemblies 12 at two sides to approach to the lower inner side and hook the slots 11 at two sides of the lock body 1 corresponding to the lower layer, so as to connect the lock bodies 1 in the vertical direction to each other, the position holding mechanism 2 is connected to the lock body 1 of the uppermost container 3, which has been moved upward at both ends thereof, and holds the current position thereof.

The using process is as follows:

the turnover boxes 3 are vertically overlapped and arranged well, the lock bodies 1 at two ends of each layer of turnover box 3 are ensured to correspond in the vertical direction (distributed on the same straight line), then, the lock bodies 1 on the multiple layers of turnover boxes 3 are enabled to move upwards by external force, in the process of upward movement of the lock bodies, the lock bodies 1 on all the turnover boxes 3 except the lowest layer drive the clamping hook components 12 at two sides to rotate and fold, and hook the clamping grooves 11 at two sides of the lock bodies 1 at the lower layer, and finally, the current positions of the lock bodies 1 at two ends of the turnover boxes 3 at the uppermost layer are fixed through the position retaining mechanism 2, so that the lock bodies on the multiple layers of turnover boxes 3 are mutually connected and retained through the matching of the clamping hook components 12 and the clamping grooves 11, finally, the multiple layers of turnover boxes 3 are firmly and stably connected into a whole, and an operator can easily carry the.

As a preferred embodiment, as shown in fig. 4 to 7, seat bodies 4 are respectively installed at both ends of each layer of the turnover box 3, a slide rail 41 penetrating up and down is provided at one end of each seat body 4 away from the turnover box 3, and the lock body 1 is slidably installed in the corresponding slide rail 41, and one end of the lock body away from the turnover box 3 leaks out of the slide rail 41.

In this embodiment, the design of the seat body 4 can facilitate the good assembly of the lock body 1 thereon, so that the lock body 1 can slide up and down well along the slide rail 41 on the seat body 4.

As a preferred embodiment, as shown in fig. 4 to 7, the hook assembly 12 includes a connecting rod 121 and a hook 122 in a hook shape vertically arranged, one end of the connecting rod 121 is hinged to a corresponding side of the lower end of the corresponding lock body 1, one end of the hook 122 is hinged to a surface of the corresponding seat 4 facing away from the container 3, and the end of the end is hinged to the other end of the connecting rod 121, the other end of the hook 122 is provided with a hook, the hook 122 on two sides of the same lock body 1 are close to each other, the lock body 1 moves upward under the action of an external force, and drives the connecting rod 121 and the hook 122 on two sides to link with each other, so that the hooks 122 on two sides are turned downward and close to each other, and hook the slots 11 of the corresponding lock body 1 on a lower layer.

In this embodiment, the hook assembly 12 is a linkage structure, and the up-and-down movement of the lock body 1 drives the connecting rod 121 and the hook 122 to link, so that the hook 122 can be turned over in a vertical plane.

In a preferred embodiment, a lid 31 is covered on the uppermost turnover container 3, and the position holding mechanism 2 is fixed to the lid 31.

In this embodiment, as shown in fig. 1 and 8, the detachable box cover 31 is provided on the uppermost-layer transfer container 3, the transfer containers 3 on the other layers can safely store the internal objects by shielding the upper-layer transfer container 3 without providing the box cover 31, and when the box cover 31 is detached, the position holding mechanism 2 is simultaneously removed, so that the position holding mechanism 2 does not affect the normal cargo handling of the transfer containers 3.

In a preferred embodiment, the upper and lower ends of two lock bodies 1 adjacent to each other vertically are in contact with each other, and when the lock bodies 1 move upward, the upper ends of the lock bodies 1 each extend beyond the upper end of the container 3 corresponding to one layer.

In this embodiment, as shown in fig. 6, 7, the mutual contact makes to connect between the lock body 1 inseparably between two adjacent lock bodies 1 from top to bottom, when removing, only need promote lock body 1 of lower floor upwards remove can realize the linkage of all lock bodies 1 on the upper and lower direction, it is more convenient to operate, it is swift, time saving and labor saving, and simultaneously, the mutual contact makes between the adjacent lock body 1 from top to bottom more firm through being connected between trip subassembly 12 and the draw-in groove 11 block back structure, locking state is more stable, make things convenient for the transport together of follow-up turnover case, avoid because of locking not compact and cause handling process turnover case 3 to have the risk that drops.

As a preferred embodiment, as shown in fig. 1 and 8, the position maintaining mechanism 2 is a link lock, lock holders 21 are fixed at two ends of the upper portion of the uppermost transfer container 3 corresponding to the positions of the lock bodies 1, two lock cylinder rods of the link lock respectively pass through the two lock holders 21, the link lock can drive the ends of the two lock cylinder rods to synchronously extend out of the two lock holders 21 or retract into the corresponding lock holders 21 under the action of external force, lock holes 32 matched with the lock cylinder rods are formed at the upper ends of the lock bodies 1 at two ends of the uppermost transfer container 3, and when the lock body 1 at the uppermost layer moves upwards to the positions of the lock holes corresponding to the lock cylinder rods, the link lock can drive the two lock cylinder rods to respectively pass through the two lock holders 21 and extend into the corresponding lock holes 32.

In this embodiment, the connecting rod lock is prior art, and its concrete structure does not do the repeated description here, unblanks or closed operation through the connecting rod lock, can order about the action that two lock core poles stretch out or retract to make the lock core pole can be quick accomplish locking or the operation of unblanking with the lockhole of the lock body 1 at the 3 both ends of uppermost layer turnover case, operation process is simple, swift relatively.

Needless to say, lock holes 32 may be formed in the lock bodies 1 at both ends of the turnover boxes 3 so that the turnover boxes 3 at each level except the lowermost level can be coupled to the position holding mechanism 2.

As a preferred embodiment, as shown in fig. 1 and 8, a handle 311 is attached to an upper portion of the lid 31.

In this embodiment, the two handles 311 are generally designed, and are respectively arranged on two sides of the link lock, and are in running fit with the box cover 31, the handles 311 can be folded and attached to the upper portion of the box cover 3, and are rotated to a vertical state when needed to be used, so that an operator can carry the multi-layer turnover box 3 simultaneously by applying external force to the handles.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
