Description

TECHNICAL FIELD

[0001] The present application belongs to the field of stacking locking device, in particular to a stacking locking system. BACKGROUND

[0002] In order to improve the unit area volume ratio, the box and other things can be easily stacked and arranged, in the prior art, in order to ensure the stability of the box and prevent it from shaking and falling, a binding belt or a frame fixed by bolts is used; however, the stability of the binding belt is poor, and the position stability cannot be guaranteed for the working condition with high stacking height, and if the frame is used for fixation, the number of boxes cannot be easily changed or the partial boxes cannot be easily transferred in batches. In the prior art, there is almost no product that can realize the rapid stacking of containers of different sizes and types, and the unlocking and locking are complex.

[0003] The prior art ZL202420787661.2 discloses a stacking locking system that can lock the boxes in the stack, which realizes the locking between the stacked boxes through a linkage locking mechanism. The sliding member is driven to move by the operating member, and the lock tongue part is driven to move by the guide groove on the sliding member. Because of the existence of the sliding member, the volume occupied in the transverse direction is large, and in order to ensure the linkage effect, the placement position of the sliding member is also limited, such as being unable to be placed on the surface of the box perpendicular to the lock tongue or being placed on the surface of the box opposite to the lock tongue. At the same time, the structure uses the sliding fit between the guide groove and the protrusion on the lock tongue to drive the lock tongue, and the protrusion is easy to be damaged due to wear and extrusion during unlocking, and the service life is limited. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the technical problem that the operating part and the lock tongue part of the locking mechanism in the prior art are limited in position and occupy a large volume in the transverse direction, and to provide a stacking locking system that is convenient to unlock and lock, modular in general scenarios, and can rapidly stack containers of different sizes and types.

[0005] The technical solution adopted by the present application to solve the technical problem is: A stacking locking system, comprising: a fixed part, a separation part and a locking mechanism; the fixed part and the separation part are connected by the locking mechanism and can be separated; The locking mechanism is provided with at least one group, and the fixed part is provided with at least one group of lock grooves matched with the locking mechanism and at least one group of contacts; The locking mechanism comprises: A containing part is arranged in the cavity of the separation part; The mortise lock is slidably connected to the receiving part via a sliding seat provided in the separating part, and the end of the mortise lock is provided with a locking tongue that can be inserted into or separated from the locking groove. The control component is connected to a movable, relatively separable part, and a control seat is provided at the end of the control component; The pusher is synchronously connected to the locking component. The end of the pusher is provided with a driven seat. A linkage is provided between the driven seat and the control seat. The two ends of the linkage are movably connected to the driven seat and the control seat, respectively. In addition, a reset member is used to drive the push member to reset and move, and a control member is used to drive the push member to reset and move.

[0006] As a further improvement of the present invention, the pusher is detachably and synchronously connected to the locking member via a connecting portion; The pusher component can be separated through the joint, which facilitates separate arrangement and reduces the complexity of individual components.

[0007] As a further improvement of the present invention, the connecting part includes a slot and a plug that are plugged into each other, and the contact surfaces of the slot and the plug are arranged perpendicular to the connecting direction of the lock groove and the lock tongue. The joint is connected to the insert block through a separable slot, which realizes the separate arrangement of the pusher and the locking part, and also reduces the damage that may be caused by stress concentration at the connection position under the integrated structure of the pusher and the locking part.

[0008] As a further improvement of the present invention, the slot is integrally disposed on a bottom surface of the locking member, and the insertion block is integrally fixed to the pushing member; The slot is integrated into the locking component, ensuring structural strength, while the insertion block is integrated into the pushing component, simplifying the structure.

[0009] As a further improvement of the present invention, the locking mechanism further includes a braking member, which is movably connected to the pushing member. A limiting groove is provided through the sliding seat, and the braking member can move through the limiting groove and contact the contact. The braking component can lock the position of the pushing component after unlocking, eliminating the need for additional retraction of the locking tongue on the locking component during the stacking process of the fixed and separating parts.

[0010] As a further improvement of the present invention, the insertion direction of the contact and the limiting groove is parallel to the stacking direction of the fixing part and the separating part and perpendicular to the engagement direction of the locking groove and the locking tongue. The contacts can be easily unlocked from the braking element by stacking the fixed and separating parts, which is simple and convenient.

[0011] As a further improvement of the present invention, the braking component is rotatably connected to the pushing component via a rotating seat. The rotation axis of the rotating seat is set parallel to the engagement direction of the locking groove and the locking tongue. A driving component is provided between the rotating seat and the pushing component. The braking component passes through the limiting groove by the driving component. The braking component uses rotational fixing, which does not require additional limiting structures compared to sliding fixing, reducing structural complexity. Moreover, the tolerance control of rotation is more convenient than that of sliding, further improving the accuracy of the braking component.

[0012] As a further improvement of the present invention, the driving component includes a helical spring that drives the braking component to rotate relative to the rotating seat, with one end of the helical spring fixed to the braking component and the other end fixed to the rotating seat. The helical spring has a simple structure and can be synchronously sleeved onto the rotating shaft of the braking component.

[0013] As a further improvement of the present invention, the control member is slidably connected to the separation part through the guide member, the guide member is provided with two sets of limiting ends, and the control member moves back and forth between the two sets of limiting ends; The control components are connected to the separation section via guides, making them easier to operate compared to free movement.

[0014] As a further improvement of the present invention, the guide member includes a guide frame fixed to the separation part, and the control member is slidably connected to the separation part through the guide frame. The guiding direction of the guide frame is arranged perpendicular to the direction of connection between the fixed part and the separation part. The guide frame allows the guide components to slide precisely.

[0015] As a further improvement of the present invention, the linkage includes a connecting rod, with its two ends rotatably connected to the driven seat and the control seat, respectively; the rotation plane of the connecting rod is arranged perpendicular to the stacking direction of the fixed part and the separating part. The linkage structure has good rigidity, precise transmission, and is easy to shape and process.

[0016] As a further improvement of the present invention, the receiving part includes a limiting member covering the bottom of the separating part, the sliding seat includes a bottom sliding support surface disposed on the surface of the limiting member and a top sliding support surface disposed on the bottom of the separating part, and the two end faces of the locking member perpendicular to the direction of the connection between the fixing part and the separating part are limited and supported by the bottom sliding support surface and the top sliding support surface. The limiting component can stably limit the movement of the locking component, and also makes it easier to install the locking component during later maintenance and assembly.

[0017] As a further improvement of the present invention, a sliding groove is provided at the bottom of the separating part, and the top end of the pushing member perpendicular to the direction of the connection between the fixed part and the separating part is slidably connected in the sliding groove, and the bottom end of the pushing member perpendicular to the direction of the connection between the fixed part and the separating part is in sliding contact with the aforementioned bottom sliding support surface. The pusher is guided and limited vertically by a sliding groove and a bottom sliding support surface, making the structure simpler.

[0018] As a further improvement of the present invention, a first limiting end face is provided on one side of the limiting member, and a second limiting end face is provided at the bottom of the separating part. During the movement of the pushing member, both ends are limited by contacting the first limiting end face and the second limiting end face respectively. A limiting hole is provided on the first limiting end face, and the aforementioned locking tongue can move through the limiting hole and contact the locking groove. The connector is guided and limited by a limiting component, making the structure simpler and eliminating the need for additional guiding and limiting structures.

[0019] As a further improvement of the present invention, a guide member is fixed on the second limiting end face, and a guide hole is provided in the locking member, with the guide member sliding in contact with the guide hole. The guide step can limit the locking part in the direction of the engagement between the separating part and the fixing part, which facilitates the pre-fixation of the locking part during assembly, and can also help guide and improve its stability.

[0020] As a further improvement of the present invention, the fixing part is provided with at least one positioning groove with a tapered structure, the inner wall of the positioning groove is provided with at least one set of guide surfaces, the guide surfaces are inclined to the bottom surface of the positioning groove, and a locking groove and a contact are provided on two adjacent sets of guide surfaces; the aforementioned receiving part is a bottom inlay seat of the locking mechanism along the direction of the combination of the fixing part and the separating part, the bottom inlay seat and the positioning groove are interlocked, and the outer wall of the bottom inlay seat is provided with a positioning surface that contacts the guide surface; The positioning groove and the receiving part can automatically align the fixed part and the separating part through the positioning guide of the positioning groove, which facilitates the locking mechanism. At the same time, the guide surface also provides stable contact and fixation for the combination of the fixed part and the separating part.

[0021] As a further improvement of the present invention, the fixing part is a rectangular structure, and positioning grooves are arranged in an array on the fixing part; the separating part is arranged in an array of locking mechanisms, and the positioning groove array is set as a repeating array of the locking mechanism array. The repeating array allows the separating part to be randomly combined with any position of the fixed part, and also enables a non-uniform number of stepped stacks, thus optimizing the stacking form.

[0022] The beneficial effects of this invention are: This invention features a linkage component that drives the latch based on a movable intermediate part for rapid locking or unlocking. It improves upon existing technologies by allowing the intermediate part to be freely arranged according to the shape of the housing, enabling the operating part and the latch to be positioned on different housing surfaces. Furthermore, the linkage mechanism is more precise, ensuring accurate transmission over long spans. The operating part can also be positioned across the housing. In addition, compared to the frictional contact of existing technologies, the linkage driven by relative sliding has a longer service life. Secondly, the number of movable connectors and transition structures can be increased to enhance the freedom of control component placement. Thirdly, the linkage components of the movable connection allow for stacking of the latch and drive component, reducing the planar projection area of ​​the structure. Fourthly, the free splicing capability allows for quick and precise stacking and storage in any direction. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0027] like Figures 1-12 A stacking locking system for fixing stacked boxes mainly includes a fixing part disposed on the top of the box, a separating part disposed on the bottom of the box, and a locking mechanism disposed on the separating part (the positions of the fixing part and the separating part can be interchanged equivalently), and the fixing part and the separating part are detachably connected by the locking mechanism. At least one locking mechanism is provided on the separating part, and at least one locking groove 1-3 that cooperates with the locking mechanism and at least one contact 1-4 are provided on the fixing part; The locking mechanism includes: The receiving part is fixed to the bottom of the separating part; The mortise lock 6 is slidably connected to the receiving part via a sliding seat provided in the separation part. The end of the mortise lock 6 is provided with a locking tongue 6-1 that can be inserted into or separated from the locking groove 1-3. Control component 5 is movably connected to the relative separation part. Control component 5 has a control seat 5-4 at its end. Control seat 5-4 moves synchronously with locking component 6 via a linkage component. Pushing component 7 is synchronously connected to locking component 6. A driven seat 7-3 is provided at the end of the pushing component 7. A linkage component is provided between the driven seat 7-3 and the control seat 5-4. The two ends of the linkage component are movably connected to the driven seat 7-3 and the control seat 5-4, respectively. Braking component 9 is movably connected to pushing component 7. A limiting groove 4-2 is provided through the sliding seat. Braking component 9 can move through the limiting groove 4-2 and contact the contact 1-4. The direction of the limiting groove 4-2 of braking component 9 is arranged perpendicular to the moving direction of the locking tongue 6-1 of the locking component to prevent the movement of the locking tongue 6-1 from obstructing the combination of contact 1-4 and limiting groove 4-2. In addition, a reset component is used to drive the pusher 7 to reset and move, and a control component 5 is used to drive the pusher 7 to move actively.

[0028] When the housings are stacked, the contact 1-4 inserts into the limiting groove 4-2, which in turn pushes the brake 9, causing the brake 9 to disengage from the limiting groove 4-2. The reset component then drives the pusher 7 and the control component 5, thereby moving the locking component 6 and inserting the locking tongue 6-1 into the locking groove 1-3, thus locking the stacking system. When separation is required, the control component 5 is pulled, which drives the locking component 6 to move in the opposite direction through the linkage component. The locking tongue 6-1 is pulled out of the locking groove 1-3, and then the housings separate. That is, when the fixed part and the separating part separate, the contact 1-4 separates from the limiting groove 4-2. Then the brake 9 re-inserts into the limiting groove 4-2, locking the pusher 7 and locking the locking component. This makes it convenient for the next stacking without needing to retract the locking tongue 6-1 by driving the control component 5.

[0029] like Figure 1 and Figure 2 The insertion direction of the contact 1-4 and the limiting groove 4-2 is parallel to the stacking direction of the fixing part and the separating part and perpendicular to the combination direction of the locking groove 1-3 and the locking tongue 6-1. Specifically, contacts 1-4 are vertically mounted on the surface of the fixing component. Contacts 1-4 can be vertically inserted into the limiting groove 4-2 during the stacking process without any additional action.

[0030] like Figures 5-9 The pusher 7 is detachably and synchronously connected to the locking member 6 via a connecting part; the connecting part includes a slot 6-2 and a plug block 7-2 that are plugged into each other, and the contact surfaces of the slot 6-2 and the plug block 7-2 are arranged perpendicular to the engagement direction of the lock groove 1-3 and the lock tongue 6-1; the slot 6-2 is integrally disposed on one side of the locking member 6, and the plug block 7-2 is integrally fixed to the pusher 7; Specifically, a slot 6-2 with an open structure is provided at the bottom of the insert 7-2 perpendicular to the moving direction of the locking member 6. A long strip-shaped, separable insert 7-2 is integrally provided at the bottom of the pusher 7 and is embedded in the slot 6-2. The insert 7-2 contacts the two end faces of the slot 6-2. When the insert 7-2 moves with the pusher 7, one end face of the insert 7-2 will press against one end face of the slot 6-2. The force transmission through the end face realizes the driving of the locking member 6.

[0031] The brake element 9 is rotatably connected to the pusher element 7 via the rotating seat 7-1. The rotation axis of the rotating seat 7-1 is set parallel to the engagement direction of the lock groove 1-3 and the lock tongue 6-1. A drive element is set between the rotating seat 7-1 and the pusher element 7. The brake element 9 passes through the limiting groove 4-2 by the drive element.

[0032] like Figure 6 The driving component includes a helical spring 9-1 that drives the brake 9 to rotate relative to the rotating seat 7-1. One end of the helical spring 9-1 is fixed to the brake 9 and the other end is fixed to the rotating seat 7-1. A rotating seat 7-1 is provided inside the pushing component 7. A rotating shaft is provided inside the rotating seat 7-1. A rotating block 9-2 is integrally fixed to the end of the brake 9. The rotating block 9-2 is rotatably connected to the rotating shaft. A spring opening is provided in the middle of the rotating block 9-2. The helical spring 9-1 is sleeved at the position of the rotating shaft corresponding to the spring opening. One end of the helical spring 9-1 is in fixed contact with the brake 9, and the other end of the helical spring 9-1 is in fixed contact with the rotating seat 7-1 of the pushing component 7. The brake 9 can rotate toward the limiting groove 4-2 under the drive of the helical spring 9-1 and insert into the limiting groove 4-2 to lock the pushing component 7.

[0033] The control component 5 is slidably connected to the separation part via the guide component 2-4. The guide component 2-4 is provided with two sets of limiting ends, and the control component 5 moves back and forth between the two sets of limiting ends.

[0034] like Figure 3 and Figure 5 The linkage includes a connecting rod 8, with its two ends rotatably connected to the driven seat 7-3 and the control seat 5-4, respectively. The rotation plane of the connecting rod 8 is perpendicular to the stacking direction of the fixed part and the separating part. The connecting rod 8 itself is a rigid structure, used to transmit the torque between the driven seat 7-3 and the control seat 5-4, so as to realize the precise reciprocating push of the control seat 5-4 on the driven seat 7-3.

[0035] Specifically, the connecting rod 8 can be a one-piece injection molded or cast structure, with both ends rotatably connected to the driven seat and the control seat 5-4 respectively via rotating pins; the connecting rod 8 is inclined to the moving direction of the driven seat 7-3 and the control seat 5-4, so that the driven seat 7-3 and the control seat 5-4 can be set vertically, so that the control seat 5-4 can move the driven seat while being pulled along the side wall 3 of the box. Compared with the existing technology, the operator does not need to unlock the box at the bottom of the box.

[0036] like Figure 3 and Figure 6 The guide component 2-4 includes a guide frame fixed to the separation part, and the control component 5 is slidably connected to the separation part through the guide frame. The guiding direction of the guide frame is arranged perpendicular to and parallel to the direction of the connection between the fixed part and the separation part. The control component 5 can move relative to the side wall 3 of the box through the guide frame. Specifically, a structural groove is provided on the side wall 3 of the box, and a side cover plate 5-5 is covered on the surface of the structural groove. The side cover plate 5-5 is fixed to the side wall 3 of the box by bolts. The guide frame includes a guide frame 5-1 fixed in the middle of the side cover plate 5-5. A control component 5 is slidably connected to the back of the guide frame 5-1 by several sets of buckle structures. The control component 5 includes a sliding piece 5-2. A long strip-shaped limiting groove 4-2 is provided in the middle of the guide frame 5-1. A lever 5-3 is fixed in the middle of the sliding piece 5-2. The lever 5-3 can move back and forth along the limiting groove 4-2 to control the sliding movement. A second return spring 10-2 is provided between the top of the sliding piece 5-2 and the structural groove to realize the movement and reset of the sliding piece 5-2 toward the fixed part at the top of the box.

[0037] like Figure 3 , Figure 4 and Figure 10 The receiving part includes a limiting member covering the bottom of the separating part, and the sliding seat includes a bottom sliding support surface disposed on the surface of the limiting member and a top sliding support surface disposed on the bottom of the separating part. The two end faces of the locking member 6 perpendicular to the direction of the connection between the fixing part and the separating part are limited and supported by the bottom sliding support surface and the top sliding support surface. A sliding groove is provided at the bottom of the separating part. The top end of the pusher 7, perpendicular to the direction of the connection between the fixed part and the separating part, is slidably connected to the sliding groove. The bottom end of the pusher 7, perpendicular to the direction of the connection between the fixed part and the separating part, is in sliding contact with the aforementioned bottom sliding support surface. A guide 2-4 is fixed on the second limiting end face. A guide hole 6-4 is provided on the locking part 6. The guide 2-4 is in sliding contact with the guide hole 6-4. A first limiting end face is provided on one side of the limiting part. A second limiting end face is provided at the bottom of the separating part. During the movement, the two ends of the pusher 7 are limited by contacting the first limiting end face and the second limiting end face respectively. A limiting hole 4-3 is provided on the first limiting end face. The aforementioned locking tongue 6-1 can move through the limiting hole 4-3 and contact the locking groove 1-3.

[0038] Specifically, the enclosure includes a frame 2, with an inlay groove 2-1 on each side of the bottom of the frame 2. The limiting component includes a limiting cover 4 fixedly covering the surface of the inlay groove 2-1, and a base 4-1 with a platform-shaped structure on the limiting cover 4. The receiving portion is located within the protruding structure of the base 4-1. A guide groove 2-2 is provided at the bottom of the inlay groove 2-1, and two sets of sliding brackets 2-3 are symmetrically arranged on the inner wall of the guide groove 2-2. The locking component 6 engages with the sliding brackets 2-3. The guide groove 2-2 is slidably connected. Sliding grooves 6-3 are provided on both sides of the locking member 6. The protruding ridges of the sliding frame 2-3 are embedded in the sliding grooves 6-3, limiting the locking member 6 in the engagement direction of the fixed and separated parts. Simultaneously, the bottom of the limiting cover 4 also provides some limiting support for the locking member 6. Furthermore, a connecting piece is provided at the end and top surface of the guide groove 2-2, connecting a cylindrical guide member 2-4. A guide hole 6-4 is provided at the top of the locking member 6. A third return spring 10-3 is provided between the front end of the guide member 2-4 and the end of the guide hole 6-4, and is slidably connected to the guide frame 5-1. The third return spring 10-3 is used to drive the locking tongue 6-1 of the mortise lock member 6 to insert into the lock groove 1-3. At the same time, an auxiliary slide groove 6-3 is integrally provided on the top of the inlay groove 2-1. The second limiting end face is provided at the bottom of the auxiliary slide groove 6-3. An auxiliary sliding piece is provided in the auxiliary slide groove 6-3. The pusher 7 is slidably connected to the auxiliary slide groove 6-3 through the auxiliary sliding piece. At the bottom of the limiting cover 4, a first limiting end face is provided. The insert 7-2, which is integrally fixed on the pusher 7, can contact the first limiting end face to achieve sliding support. At the end of the rotating seat 7-1 of the pusher 7, a spring seat 7-4 is integrally provided. A first reset spring 10-1 is provided in the spring seat 7-4. A spring plug seat is provided in the inlay groove 2-1 of the box frame 2. The first reset spring 10-1 is provided between the spring seat 7-4 and the spring plug seat to achieve reset support for the pusher 7.

[0039] like Figure 3 andFigure 4 In addition, to simplify the structure, the two locking mechanisms can share a single limiting cover 4. That is, a bottom mounting base 4-1 for placing the receiving part is provided at each end of the limiting cover 4. A set of limiting grooves 4-2 and a set of locking grooves 1-3 are provided on the inner wall of the limiting cover 4 at the corresponding position of each receiving part. The limiting grooves 4-2 and locking grooves 1-3 face the outside of the housing. Three sets of insertion grooves 4-4 corresponding to the positions of the limiting grooves 4-2 are also provided at the remaining positions of the limiting cover 4 corresponding to each receiving part. Four sets of contacts 1-4 are provided in the fixing part. One set of contacts 1-4 is used to insert into the limiting grooves 4-2, and the other three sets of contacts 1-4 are used to insert into the insertion grooves 4-4 to improve the stability of the engagement.

[0040] like Figure 1 , Figure 2 , Figure 11 and Figure 12 Furthermore, to enhance the structural freedom, the vertical projection of the fixing part is a rectangular structure. Several positioning grooves 1-1 are arranged in a matrix array on the fixing part. Each positioning groove 1-1 is a concave trapezoidal groove structure. The positioning grooves 1-1 are arranged adjacent to each other. Four sets of guide surfaces 1-2 are provided on the inner wall of the positioning groove 1-1. The guide surfaces 1-2 are inclined to the bottom surface of the positioning groove 1-1. The separating part is also a rectangular structure. At each of the four rectangular corners of the separating part, there is a bottom inlay seat 4-1 with four inclined surfaces. The side wall of the bottom inlay seat 4-1 is provided with a positioning surface corresponding to the guide surface 1-2. The positioning surface and the guide surface 1-2 are in contact with each other.

[0041] The positioning groove 1-1 and the receiving part can be automatically aligned by the positioning guide of the positioning groove 1-1, which facilitates the locking mechanism. At the same time, the guide surface 1-2 also provides stable contact and fixation for the combination of the fixing part and the separating part.

[0042] like Figure 1 , Figure 2 , Figure 11 and Figure 12In this embodiment, the box mainly includes a box frame 2, whose bottom is locked to the box cover assembly 1 of other boxes by a locking mechanism. The box cover assembly 1 includes a box cover base 1-5, on which a number of support ribs are provided. The support ribs form a number of rectangular support openings for accommodating positioning slots 1-1. A positioning opening 1-6 is provided in the middle of the support opening. A box cover is fixedly covered on the box cover base 1-5. A number of positioning slots 1-1 are arranged in an array on the box cover. The bottom of the positioning slots 1-1 is embedded in the aforementioned positioning openings 1-6. The support ribs are arranged on the connecting part between adjacent positioning slots 1-1 to support the cover. The box cover assembly 1 is combined with the box frame 2 by two sets of buckles arranged at the top of the box. A handle 3-1 is also rotatably connected to the side wall 3 of the box frame 2 to facilitate the movement of the box.

[0043] Specifically, such as Figure 1 and Figure 11 The fixed part is provided with a plurality of positioning slots arranged in an array, and the positioning slots are arranged adjacent to each other. Meanwhile, the separating part is provided with a locking mechanism arranged in an array. The array spacing and arrangement of the locking mechanism correspond to the array pattern of the positioning slots on the fixed part. Further, the fixed part is a rectangular structure, and the number of positioning slots is greater than or equal to the number of locking mechanisms. The separating part is provided with a locking mechanism, and the positioning slot array is set as a repeating array of the locking mechanism array. The distance between the bottom inlay seats 4-1 is a multiple of the positioning slots 1-1. In this embodiment, any fixed part is combined with a separating part, and four sets of locking mechanisms are provided, and the rectangular... The arrangement of the locking mechanisms involves an array spacing equal to the spacing of a positioning slot, which is also arranged in a rectangular array. This allows the upper cabinet (the separating section) to be stacked on top of the lower cabinet in any direction. Furthermore, if the number of fixing parts is greater than or equal to the number of separating parts, the separating parts can be fixed in any direction to the positions where they mate with the fixing parts, enabling free combination according to the user's selection of any direction and number. Simultaneously, the top cover of the cabinet is also equipped with a separating part, allowing for arbitrary vertical stacking. Several sets of adjacent cabinet covers on a plane can be combined to form a single vertical bottom. Additionally, the separating parts can also be equipped with other numbers of locking mechanisms, such as fewer than...
