In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

As shown in fig. 1 to 8, 10 and 12, the multidirectional adjustment apparatus of the present embodiment includes: a first direction-adjusting structure 10 and a second direction-adjusting structure 20. The first direction-adjusting structure 10 includes a first mounting seat 11, a rotating member 12 disposed on the first mounting seat 11, a direction-adjusting locking hook 13 movably disposed on the rotating member 12, and a first driving member 14 and a second driving member 15 disposed in the rotating member 12. The first driving member 14 can drive the direction-adjusting locking hook 13 to move towards a first direction, and the second driving member 15 can drive the direction-adjusting locking hook 13 to move towards a second direction opposite to the first direction. When the rotating part 12 rotates, the direction-adjusting locking hook 13 can be driven to rotate, so that the direction-adjusting locking hook 13 has a locking position and an unlocking position. The second direction-adjusting structure 20 includes a second mounting seat 21 and an adjusting lever 22 disposed in the second mounting seat 21, the direction-adjusting locking hook 13 is engaged with the adjusting lever 22 when rotated to the locking position (shown in fig. 10), and the direction-adjusting locking hook 13 is disengaged from the adjusting lever 22 when rotated to the unlocking position (shown in fig. 12).

By applying the technical solution of the present embodiment, the first direction-adjusting structure 10 can be installed on one of the two adjacent boxes 30, and the second direction-adjusting structure 20 can be installed on the other of the two adjacent boxes 30. In this embodiment, when the direction-adjusting locking hook 13 is in the locking position, and the first driving element 14 drives the direction-adjusting locking hook 13 to move towards the first direction, the direction-adjusting locking hook 13 drives the adjusting rod 22 to move towards the first direction so as to adjust the distance between the first direction-adjusting structure 10 and the second direction-adjusting structure 20, and thus the gap between two adjacent boxes 30 can be adjusted. Or when the second driving member 15 drives the direction-adjusting locking hook 13 to move towards a second direction opposite to the first direction, the direction-adjusting locking hook 13 drives the adjusting rod 22 to move towards the second direction, so that the distance between the first direction-adjusting structure 10 and the second direction-adjusting structure 20 can be adjusted again, and further, the gap between two adjacent boxes 30 can be adjusted. Then, the adjusting rod 22 rotates and pushes the direction-adjusting locking hook 13 to move along the axial direction of the adjusting rod 22 to adjust the distance between the first direction-adjusting structure 10 and the second direction-adjusting structure 20, so that the height difference between two adjacent boxes 30 can be adjusted. Like this, can enough adjust the gap between two adjacent boxes 30 through one set of multidirectional adjusting device, can adjust the difference in height between two boxes 30 again, and the function is various. Therefore, the technical scheme of the embodiment can solve the problem that in the related art, only the gap between the adjacent boxes is adjusted, so that the function is single.

It should be noted that the first direction and the second direction are both along a direction perpendicular to the axis of the adjustment lever 22. Specifically, the first direction is a leftward direction or an upward direction, and the second direction is a rightward direction or a downward direction.

As shown in fig. 2 to 4 and 8, the first direction-adjusting structure 10 further includes a limiting member 16 disposed in the rotating member 12, and the limiting member 16 is in limiting fit with the direction-adjusting locking hook 13. During the switching process of the direction-adjusting locking hook 13 from the unlocking position to the locking position, the limiting member 16 limits the direction-adjusting locking hook 13 and prevents the direction-adjusting locking hook 13 from being separated from the rotating member 12. Meanwhile, the limiting member 16 can limit the moving range of the direction-adjusting locking hook 13, so that the direction-adjusting locking hook 13 can move along the direction perpendicular to the axis of the adjusting rod 22.

As shown in fig. 2 to 4 and 8, the rotating member 12 is provided with a first limiting hole 121, and the direction-adjusting locking hook 13 is provided with a second limiting hole 131 correspondingly engaged with the first limiting hole 121. The axis of the first limiting hole 121 is perpendicular to the moving direction of the direction-adjusting locking hook 13, and the limiting member 16 includes an elastic member. The elastic member is located in the first and second position-limiting

holes

121 and 131. The first limiting hole 121 and the second limiting hole 131 are disposed to provide an installation space in the rotating member 12, and the rotating member 12 can accommodate the limiting member 16, so that the first direction adjusting structure 10 is compact. The elastic member has elasticity, and when the direction-adjusting locking hook 13 is in the locking position, and the first driving member 14 drives the direction-adjusting locking hook 13 to move towards the first direction, the elastic member deforms leftwards along with the movement of the direction-adjusting locking hook 13, so that the direction-adjusting locking hook 13 drives the adjusting rod 22 to move towards the first direction. Or when the second driving member 15 drives the direction-adjusting locking hook 13 to move towards a second direction opposite to the first direction, the elastic member deforms rightwards along with the movement of the direction-adjusting locking hook 13, so that the direction-adjusting locking hook 13 drives the adjusting rod 22 to move towards the second direction. In the two processes, the elastic element always applies a spreading force to the direction-adjusting locking hook 13, so that the direction-adjusting locking hook 13 can be contacted with the rotating element 12, and the direction-adjusting locking hook 13 is prevented from loosening when moving towards the first direction or the second direction.

When the first driving element 14 and the second driving element 15 do not drive the direction-adjusting locking hook 13 to move, and the first driving element 14 and the second driving element 15 are both separated from the direction-adjusting locking hook 13, the direction-adjusting locking hook 13 can be quickly reset under the action of the self elastic force of the elastic element.

The first position-limiting hole 121 of the present embodiment includes a through hole section located at the rear side of the second position-limiting hole 131 and a blind hole section located at the front side of the second position-limiting hole 131.

In this embodiment, the elastic member is a spring, but of course, the elastic member may also be a spring or an elastic body. When the elastic piece is a spring plate, the spring plate is curled and formed, so that the processing is convenient, and the forming is easy.

As shown in fig. 2 to 4 and 8 to 12, the direction-adjusting latch hook 13 is further provided with a first fitting hole 132 and a second fitting hole 133. The axis of the first fitting hole 132 is perpendicular to the moving direction of the direction-adjusting locking hook 13. The first driving member 14 is in driving fit with the hole wall of the first fitting hole 132, and the second driving member 15 is in driving fit with the hole wall of the second fitting hole 133. Like this, the cooperation simple structure of first driving piece 14 and the pore wall of first mating holes 132 can optimize the overall structure of first accent to structure 10 for it is simple that first accent is to structure 10 overall structure, avoids the first structure of transferring to structure 10 complicated, and the easy confusion that leads to or lose the part. Second driving piece 15 and second mating hole 133's pore wall cooperation simple structure can optimize the first overall structure who transfers to structure 10 for first transferring to structure 10 overall structure is simple, avoids first transferring to structure 10's structure complicacy, and the easy confusion that leads to or lose the part. In order to optimize the structural layout simultaneously, the production, the manufacture and the installation are convenient. Specifically, the first and second

fitting holes

132 and 133 are respectively located at both sides of the second stopper hole 131. As shown in fig. 2 to 4 and 8 to 12, the first driving member 14 includes a first driving post 141, and a first operating hole 142 and a first driving tapered surface 143 respectively provided at both ends of the first driving post 141. The first driving taper 143 is in driving engagement with the wall of the first engagement hole 132. The second driving member 15 includes a second driving post 151 and second operating holes 152 and a second driving tapered surface 153 respectively provided on both ends of the second driving post 151. The second driving tapered surface 153 is in driving engagement with the wall of the second engagement hole 133. The first operating hole 142 is operated to rotate the first driving post 141 on the rotating member 12, the first driving conical surface 143 can be in driving fit with the hole wall of the first fitting hole 132, and the first driving member 14 pushes the direction-adjusting locking hook 13 to move towards the first direction, so that the adjusting speed is higher. The second operating hole 152 is operated to rotate the second driving post 151 on the rotating member 12, the second driving cone 153 can be in driving fit with the hole wall of the second fitting hole 133, and the second driving member 15 pushes the direction-adjusting locking hook 13 to move towards the second direction, so that the adjusting speed is higher. The arrangement of the first operation hole 142 and the first driving conical surface 143 enables the first driving member 14 to perform two functions of operation and driving, so that the structural layout of the first direction-adjusting structure 10 is optimized, and the operation is convenient and easy to achieve. The second operation hole 152 and the second driving cone 153 are arranged to enable the second driving member 15 to perform two functions of operation and driving, so that the structural layout of the first direction-adjusting structure 10 is optimized, and the operation is convenient and easy to achieve. In this embodiment, the rotating member 12 is provided with a first adjusting hole for installing the first driving member 14 and a second adjusting hole for installing the second driving member 15, a first thread structure is provided between the first adjusting hole and the first driving post 141, and a second thread structure is provided between the second adjusting hole and the second driving post 151.

When both the first driving member 14 and the second driving member 15 are disengaged from the direction-adjusting latch 13, the axis of the first driving post 141 and the axis of the first engagement hole 132 are displaced, and the axis of the second driving post 151 and the axis of the second engagement hole 133 are displaced. Thus, in the process of driving and matching the first driving member 14 with the hole wall of the first matching hole 132, the first driving conical surface 143 can drive the hole wall of the first matching hole 132. In the process of driving and matching the second driving member 15 with the hole wall of the second matching hole 133, it can be ensured that the second driving tapered surface 153 drives the hole wall of the second matching hole 133.

As shown in fig. 2 to 4 and 8 to 12, the first mounting seat 11 is provided with a first mounting hole 111 and a first avoiding groove 112 communicating with the first mounting hole 111. The rotating member 12 is installed in the first installation hole 111, the rotating member 12 is provided with a guide hole 123 communicating with the first avoiding groove 112, and a part of the direction-adjusting lock hook 13 is inserted into the guide hole 123 and the first avoiding groove 112. The guiding hole 123 is disposed to facilitate the direction-adjusting locking hook 13 to move along a predetermined moving track in the rotating member 12, so as to perform a guiding function. The arrangement of the first avoiding groove 112 enables a part of the direction-adjusting latch hook 13 to be located in the first direction-adjusting structure 10, so that on one hand, the space in the box body can be saved, and on the other hand, the structure of the first direction-adjusting structure 10 can be more compact.
