BACKGROUND INFORMATION

In order to facilitate the user in the case of carrying multiple storage boxes (such as toolboxes) to facilitate the overall movement and use, each storage box is usually stacked together, and each storage box is usually locked together by interlocking, so as to facilitate the user to move and use. A number of ways are known for interlocking storage boxes. Now on the market, there are roughly the following three forms of locking: the first way uses a single plastic latch that can be turned to clasp the lower bottom of the box protrusion to achieve the purpose of interlocking; the second way is the conventional use of the front of the two-segment latch moved to the side to lock between the upper and lower boxes; and the third way uses a combination of steel wire and plastic to lock boxes together at the side. However, the above locking methods can only be interlocked for the same length and width of the shape of the box, and cannot be interlocked for different length and width of the size of the shape of the box, with many professional users needing to carry more and more diverse types of tools, there is an urgent need for interlocking between different sizes of the box.

The stacking of the storage boxes is not limited to the stacking and locking of the secondary storage boxes300at the top of the main storage box100, but also to the stacking and locking of multiple secondary storage boxes300in the middle of the two main storage boxes100.

In some embodiments, shown in conjunction withFIGS.2,3, and5, the first locking mechanism120and the second locking mechanism130of the main storage box100are both retractable structures, and the first locking mechanism120of the main storage box100or the second locking mechanism130of the main storage box100are capable of moving relative to the first box body110to form a first locking gap on the first end face111of the first box body110in the first or a second locking gap in the first direction on the first end face111of the first box body110so that the secondary storage box300can be confined in the first locking gap of the main storage box100to achieve interlocking of the main storage box100and the secondary storage box300, or so that one main storage box100is confined in the second locking gap of the other main storage box100The interlocking between the two main storage boxes100is achieved.

Specifically, in a preferred embodiment, as shown inFIGS.9and10, the first locking mechanism120includes a first connecting shaft121and a first snap hook122provided on the first box body110, and a first recess115is provided at the location where the first locking mechanism120is installed on the first end face111of the main storage box100. The first connection shaft121is preferably two, and one end of the two first connection shafts121is fixed to two opposite side walls of the first recess115in the second direction, and the two first connection shafts121are coaxially provided, and the end of the first snap hook122near the first recess115is provided with two mounting brackets for mounting the first connection shaft121. The first snap hook122is provided with two mounting holes1221near the first recess115for mounting the first connection shaft121, and each mounting hole1221is provided with one first connection shaft121, so that the first snap hook122can rotate around the central axis of the two first connection shafts121to realize the turning of the first locking mechanism120.

When the first locking mechanism120of the main storage box100snaps into the first locking bit340of the secondary storage box300, the first snap hook122rotates relative to the first connection shaft121so that the end of the first snap hook away from the first connection shaft121protrudes from the first recess115, while the bent portion of the first snap hook122hooks and holds against the outer wall of the ribbed position and cooperates with the second locking mechanism130to form the first locking gap thereby limiting the displacement of the main storage box100and the secondary storage box300in the first direction and the second direction. When it is not necessary to interlock the main storage box100and the secondary storage box300, the first snap hook122is rotated in the opposite direction with respect to the first connection shaft121so that the first snap hook122is completely accommodated in the first recess115, thereby keeping the first end face111of the main storage box100flat.

It is to be noted that the movable way of the first locking mechanism120relative to the second box310is not limited to a rotatable movable way, but may also be a retractable movable way. One end of the first snap hook122is movably mounted and housed in the first recess115, and when the locking between the storage boxes is required, the end of the first snap hook122mounted in the first recess115moves in the first direction toward the secondary storage box300so that the other end extends out of the first recess115and snaps into the first locking bit340, thereby forming a fit between the first snap hook122and the second locking mechanism130to form a first locking gap in the first direction on the first end face111of the main storage box100. When it is not necessary to interlock the main storage box100with the secondary storage box300, the first snap hook122is moved in the first direction toward the first box body110of the main storage box100so that the first snap hook122is fully accommodated in the first recess115.

As shown inFIG.11,FIG.12andFIG.15, the structure of the second locking mechanism130is described with the second locking mechanism130installed in the main storage box100as an example. A first embodiment of the second locking mechanism130is shown in the figure, and the second locking mechanism130includes a second attachment shaft131and a second snap hook132, and a second recess116is provided at the location where the second locking mechanism130is installed on the first end face111of the main storage box100, and the second recess116is provided at the edge of the first end face111, and the second recess116is open along the first direction and the second The second recess116is opened at the edge of the first end face111and the second recess116is open at one end in the first and second directions. The two ends of the second attachment shaft131are fixed to two opposite side walls of the second recess116along the third direction perpendicular to each other, and the second snap hook132is provided on the second attachment shaft131so that the second snap hook132can rotate around the central axis of the second attachment shaft131.

As shown in conjunction withFIG.1,FIG.15andFIG.16, when the second locking mechanism130of the main storage box100snaps into the second locking bit140of the secondary storage box300, or when the second locking mechanism130of one main storage box100snaps into the second locking position140of the other main storage box100, the second snap hook132is rotated relative to the second attachment shaft131to be fully accommodated in the second recess116so that the second locking mechanism130can cooperate with the first locking mechanism120so as to form a first locking gap in the first direction on the first end face111of the main storage box100, or so that the two second locking mechanisms130of the main storage box100can cooperate so as to form a second locking gap in the first direction on the first end face111of the main storage box100, when the side of the first box body110remains flat while the bent portion of the second snap hook132hooks the bottom cavity wall of the holding cavity of the mount in the second locking bit140and holds against the side cavity wall of the holding cavity of the mount to limit the mutual displacement between the main storage box100and the secondary storage box300or between the two main storage boxes100in the second direction and the third direction.

When it is not necessary to interlock the main storage box100and the secondary storage box300or when it is not necessary to lock the two main storage boxes100to each other, the second snap hook132is rotated in the opposite direction relative to the second attachment shaft131so that the end of the second snap hook132away from the second attachment shaft131extends out of the second recess116.

As shown inFIG.13,FIG.14andFIG.16, again taking the second locking mechanism130installed in the main storage box100as an example, a second embodiment of the second locking mechanism130is shown, and unlike the first embodiment of the second locking mechanism130, the second locking mechanism130is movable in a retractable movable manner relative to the first box body110. Specifically, the second locking mechanism130includes two rails133, the rails133are fixed to the bottom wall of the second recess116in the second direction, and the bottom of the second snap hook132is provided with two travel slots (not shown) matching the rails133, each travel slot is set on one rail133to enable the second snap hook132to move in the second direction. When the second locking mechanism130of the main storage box100snaps into the second locking bit140of the secondary storage box300, or when the second locking mechanism130of one main storage box100locks the second locking bit140of the other main storage box100, the second snap hook132moves along the rail133to fully accommodate the second recess116, so that the first box body110of the main storage box100is sides of the first box body110of the main storage box100are kept flat while the bent portion of the second snap hook132is held against the side and bottom cavity walls of the holding cavity of the mount to limit mutual displacement between the main storage box100and the secondary storage box300or between the two main storage boxes100in the second and third directions. When it is not necessary to interlock the main storage box100and the secondary storage box300or when it is not necessary to lock the two main storage boxes100to each other, the second snap hook132is moved in the opposite direction along the rail133so that one end of the second snap hook132extends out of the second recess116.

The second locking mechanism320of the secondary storage box300is identical in structure to the second locking mechanism130of the main storage box100. In this embodiment, the second locking mechanism320of the secondary storage box300is structured in a retractable implementation, with locking achieved by retraction of the snap hooks. The structure of the third locking mechanism330of the secondary storage box300is similar to the rotatable implementation of the second locking mechanism320in the main storage box100, which is also locked by means of a snap hook flip, and will not be repeated here.

The above storage box set10, by using the first locking mechanism120, the second locking mechanism130, the second locking bit140, the plurality of tabs and the plurality of corresponding depressions of the main storage box100and the second locking mechanism320, the third locking mechanism330, the first locking bit340, the second locking bit350, the plurality of tabs and the plurality of corresponding depressions of the secondary storage box300in conjunction, is able to simultaneously restrict the relative displacement between two stacked boxes in the first direction, the second direction and the third direction, so as to achieve the purpose of interlocking.

When the user needs to use a single storage box, the interlocked storage boxes in the storage box set10need to be unlocked. When unlocking two main boxes100of the same size, it is necessary to first unlock the second locking mechanism130of one main storage box100, pull out the second snap hook132relative to the first box body110of the main storage box100to protrude from the side of the first box body110, so that the second snap hook132is free from the second locking bit140, and then unlock the other second locking mechanism130so that the second snap hook132of the other second The second snap hook132of the other second locking mechanism130is released from its corresponding second locking bit140, thereby unlocking the two main storage boxes100of the same size. When unlocking two main storage boxes100and secondary storage boxes300of different sizes, taking the secondary storage boxes300stacked on top of the main storage boxes100as an example, the second locking mechanism130of one first storage box100is unlocked first, and then the first locking mechanism120is unlocked so that the first snap hook122of the first locking mechanism120is detached from the first locking bit340of the corresponding secondary storage box300, thus realizing the unlocking of two main storage boxes100of the same size.
