In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0103] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0104] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0105] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0106] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0107] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0108] Storage boxes, storage baskets and other storage tools in the related art generally only have internal spaces that can be used for storage, which makes it relatively inconvenient to take things out and has relatively simple storage functions.

[0109] Based on this, see Figures 1a to 6 The present application provides a stacking and hanging device 1000, which includes a stacking member 1 and a hanging structure 100, one side of the hanging structure 100 is installed on the stacking member 1, and the other side is used to connect the items 300 to be received; or, one side of the hanging structure 100 is connected to the stacking member 1, and the other side is used to be installed on the load-bearing structure 200.

[0110] In this way, the stacking members 1 in the stacking and hanging device 1000 provided in the present application can be connected and hung with other objects through the hanging structure 100, effectively expanding the storage space and function of the stacking members 1, and by changing the connection method between the hanging structure 100 and the stacking members 1, the storage position of the stacking members 1 can be made flexible and changeable, so that the stacking members 1 can be stacked on a plane or hung on a load-bearing structure 200 such as a wall according to different needs.

[0111] In some embodiments of the present application, the hanging structure 100 includes a connecting member 10 and a matching member 20. The matching member is connected to the outer peripheral wall of the stacking member 1 through the connecting member 10, and the matching member 20 is used to connect the object 300 to be received.

[0112] See also Figure 1a , Figure 2a In some embodiments, the connector 10 is fixedly connected to the stacking member 1, including but not limited to fixing with rivets 250, gluing, etc.

[0113] See also Figure 1b , Figure 2b and Figure 6 In some embodiments, the connecting member 10 may also be detachably connected to the stacking member 1 and / or movably connected to the stacking member 1, for example, by sliding connection, rotation connection, etc.

[0114] It is understood that in order to facilitate the connection member 10 to be slidably or adjustably connected to the outer peripheral wall of the stacking member 1, an auxiliary structure can be provided on the stacking member 1. For example, see Figure 2b and Figure 6 The stacking member 1 is provided with a hanging bar 230, and the connecting member 10 is provided with a snap hook 17, which is slidably snapped on the hanging bar 230. Further, the number of the snap hooks 17 is two, and the two snap hooks 17 are arranged at intervals and are respectively used to clamp the upper edge and the lower edge of the hanging bar 230. In this way, the connection between the connecting member 10 and the hanging bar 230 can be improved.

[0115] Furthermore, at least one of the snap hooks 17 is elastic, and the snap hook 17 can be loosened from the hanging bar 230 by bending the snap hook 17, thereby facilitating the removal of the connector 10 from the hanging bar 230.

[0116] Similarly, in order to facilitate the adjustment of the position of the stacking member 1 installed on the load-bearing structure 200 through the hanging structure 100, an auxiliary seat 400 can also be provided on the stacking member 1 to assist in the matching. Figure 1b and Figure 4a , Figure 5a and Figure 5b One side or both sides of the hanging structure 100 can be slidably or adjustably connected to the stacking member 1 and / or the load-bearing structure 200 through the cooperation of the auxiliary seat 400. Figure 1b and Figure 4a , Figure 5a and Figure 5b It can be understood that the auxiliary seat 400 can be a guide rail, and the auxiliary seat 400 can also be a fixed plate and a slide bar arranged on the fixed plate.

[0117] Furthermore, similarly, the mating piece 20 and the connecting piece 10 may be detachably and / or movably connected, or may be non-detachably connected. In other words, the mating piece 20 and the connecting piece 10 may be independently formed and then connected in a variety of ways such as snap-on, hinged, magnetic, etc., and the mating piece 20 and the connecting piece 10 may also be fixedly connected by rivets or directly integrally formed. For example, when the mating piece 20 and the connecting piece 10 are non-detachably connected, the mating piece 20 and the connecting piece 10 may be integrally injection molded; or, the mating piece 20 and the connecting piece 10 may be adhesively connected; or, the mating piece 20 and the connecting piece 10 may be riveted.

[0118] In order to facilitate the stacking member 1 to expand more storage functions and storage space through the hanging structure 100. In the embodiment of the present application, optionally, the matching member 20 is detachably connected to the connecting member 10. The structure of the connecting member 10 and the matching member 20 and the matching relationship between the two are further explained below through some embodiments.

[0119] See below. Figures 7 to 10 The connecting member 10 is provided with a first matching structure 11, and the matching member 20 is provided with a second matching structure 21. At least part of the second matching structure 21 is pressed on the first matching structure 11 along the gravity direction G+ to limit the matching member 20 from being separated from the connecting member 10 along the gravity direction G+. Under the action of its own gravity and the gravity of the object to be received, the matching member 20 is pressed on the first matching structure 11 through the second matching structure 21, thereby achieving a firm connection with the connecting member 10, and will not be separated from the connecting member 10 along the gravity direction G+.

[0120] Alternatively, if Figure 8 and Fig. 9 As shown, the first matching structure 11 is configured as a convex portion 111 protruding from the surface of the connector 10, and the second matching structure 21 is configured as a matching groove 201. The matching groove 201 has a first opening 211 arranged opposite to the convex portion 111. The matching groove 201 can be sleeved on the convex portion 111 through the first opening 211, and the upper wall surface of the matching groove 201 is pressed on the convex portion 111 along the gravity direction G+. In this way, the release area between the first matching structure 11 and the second matching structure 21 can be increased, so that the connection between the matching member 20 and the connector 10 is more firmly established.

[0121] Furthermore, if Fig. 9As shown, the outer peripheral wall of the convex portion 111 is provided with a limiting convex edge 112, the limiting convex edge 112 is spaced apart from the surface of the connecting member 10, and the first opening 211 is provided with a flange 212 extending toward the center of the first opening 211, and the flange 212 is stopped between the limiting convex edge 112 and the surface of the connecting member 10. By setting the flange 212 to stop between the limiting convex edge 112 and the surface of the connecting member 10, the mating member 20 can be limited from being separated from the connecting member 10 in a direction perpendicular to the surface of the connecting member 10.

[0122] Furthermore, the matching groove 201 also has a second opening 213, which is connected to the first opening 211; along the gravity direction G+, the convex portion 111 of the matching piece 20 can sequentially pass through the second opening 213 and the first opening 211 and extend into the matching groove 201. By providing the second opening 213, it is convenient to put the matching groove 201 on the surface of the convex portion 111.

[0123] The hanging structure 100 further includes a locking member 30, which is used to restrict the fitting member 20 from being separated from the connecting member 10 along the anti-gravity direction G-. Three types of the locking member 30 are described below.

[0124] First, the first embodiment of the locking member 30 is introduced:

[0125] Please continue reading Figures 7 to 9 , the matching piece 20 is provided with a third matching structure 22, and the locking piece 30 is movably connected to the connecting piece 10; and at least a portion of the locking piece 30 can be moved to a surface protruding from the connecting piece 10 close to the matching piece 20, and is used to form a stopper above the third matching structure 22 along the gravity direction G+; the locking piece 30 can be moved to a surface not protruding from the connecting piece 10 close to the matching piece 20, so as to release the stopper between the third matching structure 22. Since the first matching structure 11 and the second matching structure 21 cooperate with each other to limit the matching piece 20 from being separated from the connecting piece 10 along the gravity direction G+, by setting at least a portion of the locking piece 30 to form a stopper above the third matching structure 22 along the gravity direction G+, the matching piece 20 can be limited from being separated from the connecting piece 10 along the anti-gravity direction G-, thereby achieving complete locking of the matching piece 20 and the connecting piece 10. Furthermore, by moving the locking member 30 , the stop between the locking member 30 and the third matching structure 22 can be released, thereby unlocking the mating member 20 and the connecting member 10 , making it easier to remove the mating member 20 from the connecting member 10 .

[0126] The connecting member 10 is provided with a through hole 12; the locking member 30 includes a main body 31 and a protrusion 32 connected to each other, and the protrusion 32 can extend through the through hole 12 to the surface of the connecting member 10 close to the matching member 20; the main body 31 is movably connected to the connecting member 10 and can drive the protrusion 32 to disengage from the through hole 12. That is, the protrusion 32 is used to stop and cooperate with the third matching structure 22.

[0127] Alternatively, if Figure 8 and Fig.10 As shown, the through hole 12 is opened in the convex part 111, and the third matching structure 22 is configured as a block 202 protruding from the inside of the matching groove 201. In this way, the space of the connecting member 10 along the gravity direction G+ can be fully utilized, which is conducive to shortening the length of the connecting member 10 and the length of the corresponding matching member 20, which is conducive to saving materials and reducing costs.

[0128] The locking member 30 further includes an elastic support member 39, one end of which is connected to the connector 10, and the other end of which is pressed against the main body 31 along the axial direction of the through hole 12, so that the projection 32 can remain protruding out of the through hole 12. In this way, the projection 32 can remain in stopper engagement with the third matching structure 22 under the action of the elastic support member 39, thereby facilitating the firmness of the connection between the matching member 20 and the connector 10. Specifically, the elastic support member 39 can be a metal spring.

[0129] The projection 32 is provided with a guiding slope 321; when the main body 31 moves a preset distance along the anti-gravity direction G-, the projection 32 can be separated from the through hole 12 along the guiding slope 321. The guiding slope 321 plays a guiding role, which facilitates the projection 32 to be separated from the through hole 12. Specifically, when it is necessary to remove the matching piece 20, it is only necessary to push the main body 31 along the anti-gravity direction G-, so that the projection 32 is separated from the through hole 12 along the guiding slope 321, thereby releasing the stopper cooperation between the projection 32 and the third matching structure 22. Then, the matching piece 20 is moved along the anti-gravity direction G-, so that the second matching structure 21 and the first matching structure 11 are released from the limit, so that the matching piece 20 can be removed from the connecting piece 10. Specifically, the guiding slope 321 is arranged above the projection 32.

[0130] The connector 10 is provided with a slide groove 13, and one end of the main body 31 away from the protrusion 32 can slide along the gravity direction G+ or the anti-gravity direction G- with the side wall of the slide groove 13. The slide groove 13 plays a guiding role, so that the main body 31 can slide more smoothly relative to the connector 10.

[0131] The locking member 30 further includes an auxiliary push block 33 , which is connected to one end of the main body 31 relatively away from the protrusion 32 . The protrusion 32 can be driven out of the through hole 12 by pushing the auxiliary push block 33 along the anti-gravity direction G−.

[0132] Specifically, the auxiliary push block 33 is connected to a side of the main body 31 close to the matching piece 20, and the matching piece 20 is provided with an avoidance notch 27 corresponding to the auxiliary push block 33, and the auxiliary push block 33 is exposed through the avoidance notch 27. In this way, it is convenient for the operator to push the main body 31 to move along the anti-gravity direction G- through the auxiliary push block 33.

[0133] The locking member 30 further includes a first elastic reset member 34 , one end of which is connected to the upper wall of the slide slot 13 , and the other end of which elastically acts on the auxiliary push block 33 along the gravity direction G+.

[0134] Thus, when the operator applies force to the auxiliary push block 33 to push the auxiliary push block 33 to move in the anti-gravity direction G-, the first elastic reset member 34 is compressed. When the operator stops applying force to the auxiliary push block 33, the first elastic reset member 34 pushes the auxiliary push block 33 to drive the main body 31 to reset, so that the protrusion 32 returns to the state of being limited in the through hole 12. The first elastic reset member 34 can be configured as a spring.

[0135] For further information, please see Figure 4a , Figure 4b and Fig. 9 Optionally, when the stacking member 1 is mounted on the load-bearing structure 200 through an auxiliary seat 400 such as a guide rail, two opposite ends of the hanging structure 100 may be provided with a through slot 14, and two edges of the guide rail are respectively slidably clamped in the two through slots 14. In this way, the hanging structure 100 can slide along the extension direction of the guide rail. The through slot 14 is provided in the connecting member 10.

[0136] Optionally, the guide rail is fixed to the load-bearing structure 200 by screws.

[0137] Furthermore, along the extension direction of the guide rail, the edge of the guide rail may be provided with a plurality of positioning holes (not shown) distributed at intervals, and at least one of the two through slots 14 may be provided with a locking pin 312, which may be inserted into any of the positioning holes to position and install the hanging structure 100 on the guide rail. Thus, when the hanging structure 100 slides along the guide rail to a certain positioning hole, the hanging structure 100 may be locked on the guide rail by inserting the locking pin 312 into the positioning hole.

[0138] Furthermore, a stopper 311 is provided at one end of the main body 31 away from the protrusion 32. The stopper 311 is spaced apart from the connecting member 10 and forms a through slot 14 with the connecting member 10. The through slot 14 is used for sliding engagement with the guide rail. In this way, the main body 31 can not only play a role in driving the protrusion 32, but also can be used to form a through slot 14 with the connecting member 10 for sliding engagement with the guide rail.

[0139] Furthermore, the limiting block 311 is provided with a locking pin 312 , and the locking pin 312 can move with the auxiliary pushing block 33 to be plugged into and matched with the positioning hole.

[0140] Next, a second embodiment of the locking member 30 is introduced:

[0141] See also Figure 11-Figure 17A third matching structure 22 is provided on the connecting member 10, and the third matching structure 22 is configured as a limiting hole 203. The locking member 30 is elastic and fixedly connected to the matching member 20. As the matching member 20 moves relative to the connecting member 10, the locking member 30 can be deformed and extend into the limiting hole 203.

[0142] Furthermore, if Fig.14 As shown, the locking member 30 can be configured to be hook-shaped, so as to be easily inserted into the limiting hole 203 and stopped below the upper wall of the limiting hole 203 along the gravity direction G+.

[0143] Optionally, the locking member 30 and the matching member 20 are both plastic members and are integrally formed by injection molding.

[0144] The hooking structure 100 further includes an auxiliary push block 33, which is movably connected to the matching member 20; as the auxiliary push block 33 moves relative to the matching member 20, the auxiliary push block 33 can drive the locking member 30 to deform and disengage from the limiting hole 203. In this way, the operator can push the auxiliary push block 33 to disengage the locking member 30 from the limiting hole 203, thereby achieving the unlocking between the matching member 20 and the connecting member 10.

[0145] Furthermore, the auxiliary pushing block 33 is provided with a mating hook 331, which is slidably connected to the bottom of the locking member 30. As the mating hook 331 slides upward relative to the mating member 20, the mating hook can apply a force to the locking member 30 in a direction away from the connecting member 10, thereby causing the locking member 30 to deform and disengage from the limiting hole 203.

[0146] Specifically, the matching hook 331 is provided with a first inclined surface 332, and the locking member 30 is provided with a second inclined surface 302. The first inclined surface 332 slides against the lower side of the first inclined surface, and along the gravity direction, the first inclined surface 332 and the second inclined surface both extend in a direction away from the connecting member 10. In this way, when the matching hook 331 moves upward, the first inclined surface 332 can exert a force on the locking member 30 in a direction away from the connecting member 10 through the second inclined surface 302, so that the locking member 30 is deformed and disengaged from the limiting hole 203.

[0147] Next, the third embodiment of the locking member 30 is introduced:

[0148] See also Figures 18 to 22 The connecting member 10 is provided with a third matching structure 22, and the locking member 30 is movably connected to the matching member 20; at least part of the locking member 30 can be moved to a surface protruding from the matching member 20 close to the connecting member 10, and is used to stop below the third matching structure 22 along the gravity direction G+; the locking member 30 can be moved to a surface not protruding from the matching member 20 close to the connecting member 10, so as to release the stop between the third matching structure 22.

[0149] The fitting member 20 has an assembly cavity 23 having a first opening 231 disposed toward the connecting member 10 . The locking member 30 is movably accommodated in the assembly cavity 23 , and at least a portion of the locking member 30 can extend through the first opening 231 .

[0150] Furthermore, if Fig. 20 As shown, the assembly cavity 23 has a second opening 232 set toward the anti-gravity direction G-; the locking member 30 includes a baffle 35 and a transmission button 36, the baffle 35 extends through the first opening 231, one end of the transmission button 36 extends through the second opening 232, and the other end is movably connected to the baffle 35; as the transmission button 36 moves along the gravity direction G+, the transmission button 36 can push the baffle 35 to retract into the assembly cavity 23.

[0151] The baffle 35 is used to stop below the third matching structure 22 along the gravity direction G+; the operator presses the transmission button 36 along the gravity direction G+, and the transmission button 36 drives the baffle 35 to move toward the assembly cavity 23 until the baffle 35 does not extend out of the first opening 231, so that the baffle 35 is unblocked from the third matching structure 22. That is, by pressing the transmission button 36, the mating member 20 and the connecting member 10 can be unlocked.

[0152] The side wall of the transmission button 36 away from the first opening 231 is configured as a transmission slope 361, the baffle 35 is provided with a through hole 351, the transmission button 36 is penetrated through the through hole 351, and the transmission slope 361 is pressed against the inner wall of the through hole 351; as the transmission button 36 moves along the gravity direction G+, the transmission slope 361 can exert a force on the inner wall of the through hole 351 pointing from the first opening 231 to the assembly cavity 23. By providing the transmission slope 361, the movement of the transmission button 36 in the gravity direction G+ can be converted into the movement of the baffle 35 toward the assembly cavity 23.

[0153] The locking member 30 further includes a stopper 37, which is connected to the transmission button 36 and stops below the baffle 35 along the gravity direction G+. In this way, the stopper 37 can prevent the transmission button 36 from escaping from the second opening 232 along the anti-gravity direction G−.

[0154] Furthermore, the locking member 30 further includes a second elastic reset member 38, one end of which is connected to the bottom wall of the assembly cavity 23, and the other end of which elastically acts on the stopper 37 along the anti-gravity direction G-. The second elastic reset member 38 abuts against the stopper 37 to apply a force along the anti-gravity direction G- to the baffle 35, thereby keeping the baffle 35 confined in the assembly cavity 23.

[0155] Furthermore, in some embodiments, the connector 10 has at least one mounting surface 15 and at least one mating surface 16 , the mounting surface 15 is used to connect the stacking member 1 or the load-bearing structure 200 , and the mating surface 16 is used to connect the mating member 20 .

[0156] Optionally, in one embodiment, if Fig.18 As shown, the connector 10 has a mounting surface 15 and a mating surface 16, and the mounting surface 15 is disposed opposite to the mating surface 16. In this embodiment, each connector 10 is correspondingly mounted with a mating component 20, and the stacking component 1 or the load-bearing structure 200 and the mating component 20 are located on two opposite sides of the connector 10, so that the connector 10 is more compact.

[0157] In another embodiment, the connector 10 has multiple mating surfaces 16, so that multiple mating members 20 can be installed on the same connector 10. In this way, the stacking member 1 can be hung with objects with different functions through the same connector 10 and multiple mating members 20.

[0158] In another embodiment, the connector 10 has a plurality of mounting surfaces 15, and the plurality of mounting surfaces 15 are suitable for different load-bearing structures 200, so that the connector 10 can be switched between the plurality of load-bearing structures 200, and the hanging position of the stacking member 1 can be flexibly changed.

[0159] The fitting member 20 includes a transition portion 25 and a functional portion 26 . The functional portion 26 is connected to the transition portion 25 and is connected to the connecting member 10 through the transition portion 25 .

[0160] The functional part 26 is detachably connected to the adapter part 25. In this way, the functional part 26 can be detached from the adapter part 25, so that the functional part 26 can be replaced according to actual practical needs.

[0161] See also Figure 7 The adapter 25 is provided with at least one set of clamping components 251, each set of clamping components 251 includes two spaced and oppositely arranged clamping arms 251a, and the clamping arms 251a are used to clamp the functional part 26. The clamping arms 251a are elastic, so that the functional part can be easily clamped between the corresponding set of clamping arms 251a.

[0162] See also Fig.18 and Fig.23 The adapter 25 is provided with an assembly groove 257, and the functional part 26 is clamped in the assembly groove 257. The part of the functional part 26 located in the assembly groove 257 can be configured as a long strip to increase the contact area between the functional part 26 and the assembly groove 257.

[0163] The adapter portion 25 has an assembly hole 252 , and the functional portion 26 is disposed through the assembly hole 252 .

[0164] Specifically, see Fig.28 The adapter 25 includes a front cover 253 and a rear cover 254 that are detachably connected. The rear cover 254 is located between the front cover 253 and the connector 10. The front cover 253 is provided with a first groove 254a, and the rear cover 254 is provided with a second groove 254a. The second groove 254a and the first groove 254a enclose an assembly hole 252.

[0165] See also Fig.24 A slot 255 is disposed on the surface of the adapter portion 25 , and a hook 261 is disposed on the functional portion 26 . The hook 261 is engaged with the slot 255 .

[0166] Each functional portion 26 is correspondingly connected to at least one adapter portion 25 .

[0167] For example, in Figures 7 to 31 In the embodiment shown, each functional part 26 is connected to a corresponding adapter part 25. Figure 32-Figure 34 In the illustrated embodiment, the functional portion 26 is relatively large, and a plurality of adapter portions 25 jointly support the same functional portion 26 .

[0168] The functional part 26 is movably connected to the adapter part 25. In this way, the position of the functional part 26 relative to the adapter part 25 can be adjusted conveniently according to the use requirements.

[0169] For example, see 35 to Fig.38 The functional portion 26 is configured as a lamp 262 , and the lamp 262 is hinged to the adapter portion 25 .

[0170] The functional portion 26 is non-detachably connected to the adapter portion 25 .

[0171] Optionally, in some embodiments, the functional portion 26 may be non-detachably connected to the transition portion 25 by bonding, riveting, or the like.

[0172] Of course, the functional part 26 can also be provided integrally with the adapter part 25, for example, Fig.11 In the figure, the functional part 26 is configured as a functional plane 256 on the adapter part 25. The functional plane 256 can be used for, but not limited to, installing the tool kit 310 to wait for the object 300 to be received. The functional plane 256 can also be used for bonding other objects to be received.

In this way, by turning over the movable portion 192, the matching hole 18 can be opened, so that the connector 10 can be removed from the belt.

[0175] Furthermore, the connecting member 10 further includes a locking portion 193 , and the locking portion 193 is used to lock the movable portion 192 and the fixed portion 191 .

[0176] Optionally, the locking portion 193 is connected to the movable portion 192 and can rotate relative to the movable portion 192. When the movable portion 192 rotates to abut against the fixed portion 191, the movable portion 192 and the fixed portion 191 can be sleeved together and locked by flipping the locking portion 193.

[0177] The function of the functional unit 26 is described below using several specific embodiments as examples.

[0178] See also Figures 18 to 29 The functional part 26 is configured as a hook 263 for hanging the received items 300.

[0179] Among them, Figures 18 to 27 As shown, the hook 263 can be configured as a single hook 263, and the single hook 263 extends from the bottom of the adapter 25. It can also be directly connected to the side of the adapter 25 away from the connecting member 10.

[0181] See also Figure 30 to Figure 31 The functional part 26 is configured as a hanger 264, and a plurality of hook bodies 265 distributed at intervals are provided on the hanger 264. The plurality of hook bodies 265 are used to expand the hanging space of the hanger 264, so that more items to be received can be hung.

[0182] See also Figure 32 to Figure 34 The functional part 26 is configured as a frame structure 266 , and at least two adapter parts 25 are correspondingly connected to one frame structure 266 , and the frame structure 266 can be used to install a tray 267 , a ball frame 268 or a sheet metal frame 269 .

[0183] See also Figures 35 to 38, the functional part 26 is configured as a lamp 262, wherein, Fig.36 This is a schematic diagram of the lamp in a folded state; Fig.37 is a schematic diagram of the lamp 262 in an on state; Fig.38 for Fig.36 An exploded view of the hook structure 100 is shown; Fig.39 for Fig.36 A schematic diagram of the matching component 20 in the hanging structure 100 is shown.

[0184] The lamp 262 is hinged to one side of the adapter 25 via a hinge shaft 262a, and the lamp 262 can be turned 270° relative to the adapter 25. The lamp 262 is rotatably connected to the hinge shaft 262a via a rotating shaft 262b, and the lamp 262 can be rotated 360° relative to the adapter 25. This makes it convenient for users to adjust the lighting angle of the lamp 262 according to usage requirements.

[0185] Furthermore, an interface 258 is provided below the adapter 25, and the interface 258 can be further used for plugging in a tripod.

[0186] For further information, see Figure 39 to Figure 71 The multiple stacking members 1 of the present application can be stacked and connected up and down, and can then be carried or hung on a load-bearing structure 200 at the same time. They can remain stable in a moving state or a stored state, are not prone to slipping and separation, thereby improving safety in use and making better use of storage space.

[0187] Specifically, in some embodiments, the stacking device 1000 of the present application includes a plurality of stacking members 1, and the adjacent stacking members 1 can be stacked up and down. When the adjacent stacking members 1 are stacked up and down, the stacking member 1 located relatively to the upper one is the first stacking member 10n, and the stacking member 1 located relatively to the lower one is the second stacking member 40n; wherein, the first stacking member 10n is provided with a first matching structure; the second stacking member 40n is provided with a second matching structure 50n adapted to the first matching structure 20n, and one of the first stacking member 10n and the second stacking member 40n is restricted by the first matching structure 20n and the second matching structure 50n, so that the first stacking member 10n and the second stacking member 40n are stacked up and connected. In other words, the top of the stacking member 1 is provided with the first matching structure 20 and / or the bottom of the stacking member 1 is provided with the second matching structure 50, and the first matching structure 20 and the second matching structure 50 located on different stacking members 1 can match each other, so that different stacking members 1 are stacked up and connected. That is, each stacking member 1 may be provided with a first matching structure at the top and a second matching structure at the bottom, so that both the upper and lower sides of each stacking member 1 can be stacked and connected with other stacking members 1 .

[0188] Further explanation, that is, the first stacking member 10n and the second stacking member 40n are both stacking members 1. When multiple stacking members 1 are stacked and connected to each other, every two stacking members 1 are stacked together, and the one located on the top is the first stacking member 10n, and the one located on the bottom is the second stacking member 40n. For example, when three stacking members 1 are stacked and connected to each other, the middle stacking member 1 can be called the first stacking member 10n relative to the stacking member 1 located above it, and can be called the second stacking member 40n relative to the stacking member 1 located below it. It can be understood that the naming of the first stacking member 10n and the second stacking member 40n is only for the purpose of facilitating the understanding of the matching relationship and matching process between the first matching structure 20n and the second matching structure 50n.

[0189] In one embodiment of the present application, the first matching structure 20n and the second matching structure 50n cooperate with each other to at least limit the movement of the first stacking member 10n and the second stacking member 40n along the Z direction, which is the direction in which the stacking members 1 are connected and stacked.

[0190] In one embodiment of the present application, the first matching structure 20n and the second matching structure 50n cooperate with each other, and can also limit the movement of the first stacking member 10n and the second stacking member 40n along the X direction and / or the Y direction. For example, one of the first matching structure and the second matching structure is a groove with a notch perpendicular to the Z direction, and the other is a protrusion, and the concave and convex are plugged together to limit the movement of the first stacking member 10n and the second stacking member 40n along the Z direction and the X direction or the Z direction and the Y direction.

[0191] Furthermore, in one embodiment of the present application, a third matching structure 30n is further provided at another location on the top of the first stacking member 10n, and a fourth matching structure 60n adapted to the third matching structure 30n is further provided at another location on the bottom of the second stacking member 40n. When the first matching structure 20n and the second matching structure 50n are matched with each other, and the third matching structure 30n and the fourth matching structure 60n are matched with each other, the movement of the first stacking member 10n and the second stacking member 40n along the X direction, the Y direction and the Z direction are all restricted. In this way, the reliability of the stacking connection between the stacking members 1 can be further ensured, and the transportation and storage can be made safer and more stable, and it is not easy for some stacking members 1 to slip and fall and cause injuries to people.

[0192] Further, at least one group of first matching structures 20n and third matching structures 30n are arranged on both sides of the top X direction of the first stacking piece 10n, and the structure of the third matching structure 30n is the same as that of the first matching structure 20n and is arranged opposite to each other; at least one group of second matching structures 50n and fourth matching structures 60n are arranged on both sides of the bottom X direction of the second stacking piece 40n, and the structure of the fourth matching structure 60n is the same as that of the second matching structure 50n and is arranged opposite to each other; and / or, at least one group of first matching structures 20n and third matching structures 30n are arranged on both sides of the top Y direction of the first stacking piece 10n, and the structure of the third matching structure 30n is the same as that of the first matching structure 20n and is arranged opposite to each other; at least one group of second matching structures 50n and fourth matching structures 60n are arranged on both sides of the bottom Y direction of the second stacking piece 40n, and the structure of the fourth matching structure 60n is the same as that of the second matching structure 50n and is arranged opposite to each other.

[0193] In one embodiment, the third matching structure 30n has the same structure as the first matching structure 20n and is axially symmetrically arranged, and the fourth matching structure 60n has the same structure as the second matching structure 50n and is axially symmetrically arranged.

[0194] Furthermore, in one embodiment, the third matching structure 30n has the same structure as the first matching structure 20n and is symmetrically arranged about the central axis of the first stacking member 10n, and the fourth matching structure 60n has the same structure as the second matching structure 50n and is symmetrically arranged about the central axis of the second stacking member 40n.

[0195] Referring to FIG. 1 and FIG. 4 , further, in one embodiment, the third matching structure 30n has the same structure as the first matching structure 20n and is axially symmetrically arranged on two opposite sides of the first stack 10n with respect to the central axis of the first stack 10n, and the fourth matching structure 60n has the same structure as the second matching structure 50n and is axially symmetrically arranged on two opposite sides of the second stack 40n with respect to the central axis of the second stack 40n. It can be understood that in other embodiments, the third matching structure 30n and the first matching structure 20n can also be arranged relative to each other with respect to other axes of the first stack 10n. It can be understood that the relative arrangement includes but is not limited to an axially symmetrical arrangement, and can also be located on both sides of the axis but diagonally arranged.

[0196] It can be understood that the first matching structure 20n and the third matching structure 30n can be located on the same height plane or on different height planes. In other words, the two locations where the first matching structure 20n and the third matching structure 30n are arranged on the first stack 10n can have a height difference.

[0197] Please refer to Figures 1 and 2 again. In order to facilitate structural processing and stacking operations, in one embodiment, a group of first matching structures 20n and third matching structures 30n are arranged on both sides of the top X direction of the first stacking member 10n, and the structure of the third matching structure 30n is the same as that of the first matching structure 20n; at the same time, correspondingly, a group of second matching structures 50n and fourth matching structures 60n are arranged on both sides of the bottom X direction of the second stacking member 40n, and the structure of the fourth matching structure 60n is the same as that of the second matching structure 50n and is arranged relatively.

[0198] It can be understood that in other embodiments, one or more groups of first matching structures 20n and third matching structures 30n may be respectively arranged on both sides of the top of the first stack 10n in the X direction and both sides of the Y direction; correspondingly, one or more groups of second matching structures 50n and fourth matching structures 60n may be respectively arranged on both sides of the top of the second stack 40n in the X direction and both sides of the Y direction. Specific examples are not given in detail.

[0199] For example, in one embodiment, the first matching structure 20n and the third matching structure 30n may also be provided in two groups, wherein one group of the first matching structure 20n and the third matching structure 30n are provided on both sides of the top of the first stacking member 10n in the X direction, and the other group is provided on both sides of the top of the first stacking member 10n in the Y direction; the second matching structure 50n and the fourth matching structure 60n are also provided in two groups accordingly, wherein one group of the second matching structure 50n and the fourth matching structure 60n are provided on both sides of the bottom of the second stacking member 40n in the X direction, and the other group is provided on both sides of the bottom of the second stacking member 40n in the Y direction.

[0200] Furthermore, in other embodiments, the third matching structure 30n may also be different from the first matching structure 20n, and the fourth matching structure 60n may also be different from the second matching structure 50n, as long as the third matching structure 30n and the fourth matching structure 60n can match with each other and can limit the movement between the first stack 10n and the second stack 40n in the X direction, Y direction and Z direction together with the first matching structure 20n and the second matching structure 50n.

[0201] For example, in one embodiment, the third matching structure 30n includes a first matching portion disposed at the top of the first stacking member 10n, and the fourth matching structure 60n includes a second matching portion disposed at the bottom of the second stacking member 40n. When the second stacking member 40n is stacked on the first stacking member 10n, the first matching portion can be mutually engaged with the second matching portion to cooperate with the first matching structure 20n and the second matching structure 50n to simultaneously limit the movement of the second stacking member 40n along the X direction, the Y direction, and the Z direction. It can be understood that the first matching portion and the second matching portion can both be configured as a card plate to be mutually engaged, or one can be a groove and the other can be a protrusion to be mutually engaged.

[0202] It can be further understood that, in one embodiment, the stacking device 1000 further includes a fifth matching structure 12n and a sixth matching structure 41, the fifth matching structure 12n is arranged at the top of the first stacking member 10n, and the sixth matching structure 41 is arranged at the bottom of the second stacking member 40n, and when the second stacking member 40n is stacked on the first stacking member 10n, the fifth matching structure 12n and the sixth matching structure 41 can cooperate with each other to limit the movement of the second stacking member 40n along the X direction and the Y direction. In other words, on the basis of the mutual cooperation of the first matching structure 20n, the second matching structure 50n, the third matching structure 30n and the fourth matching structure 60n, other matching structures can be added according to needs to further assist in limiting, so as to ensure that after the first stacking member 10n and the second stacking member 40n are stacked and connected, relative displacement between the two is not likely to occur.

[0203] The following further describes the method and structure for realizing stacking connection between the stacking components 1.

[0204] See also Figure 39 to Figure 55 , for example, referring to the first embodiment of the stacking connection between the stacking members 1 of the present application, in this embodiment, the stacking hanging device 1000 includes two stacking members 1, and both stacking members 1 are storage boxes. Optionally, the storage boxes are both rectangular parallelepipeds, and the two are the same size. It can be understood that in other embodiments, the specific function of the stacking member 1 is not limited, and the stacking member 1 can be a storage box, a cart, or a storage basket, etc., and the specific size is not limited.

[0205] In the present application, the stacking device 1000 has a locked state, in which the first stacking member 10n and the second stacking member 40n can be locked in three directions X, Y, and Z by the pressure of the upper stacking member. The "pressure" may be only the gravity generated by the upper stacking member 1 itself, or the pressure generated by the gravity generated by the upper stacking member 1 itself and the external force applied to the upper stacking member 1.

[0206] For example, in this embodiment, the X direction, the Y direction, and the Z direction correspond to the length direction, the width direction, and the height direction of the storage box, respectively; it should be noted that in this embodiment, the height direction is also the direction in which the first stacking member 10n and the second stacking member 40n are stacked and extended. It can be understood that when the storage box is in the shape of a polygonal prism or a cylinder, the X direction, the Y direction, and the Z direction can be determined according to the specific situation.

[0207] It can be understood that in the same stacking device 1000, when the X-direction, Y-direction, and Z-direction coordinate systems are determined, the correspondence between the length direction, width direction, and height direction of different stacking components and the X-direction, Y-direction, and Z-direction is related to the length, width, height, and placement direction of the stacking component, and needs to be corresponded according to specific circumstances. For example, in the same X-direction, Y-direction, and Z-direction coordinate system, the length direction, width direction, and height direction of the first stacking component 10n can correspond to the X-direction, Y-direction, and Z-direction, respectively, while the length direction, width direction, and height direction of the second stacking component 40n can correspond to the Y-direction, X-direction, and Z-direction, respectively.

[0208] For example, in the first embodiment provided in the present application, the first matching structure 20n includes a first elastic member 21n and a first movable member 22n, the first elastic member 21n can elastically act on the first movable member 22n, when the second stacking member 40n is stacked on the first stacking member 10n, the first movable member 22n can move on the first stacking member 10n under the pressure of the second stacking member 40n; when the second stacking member 40n is stacked in place, the first movable member 22n can make the first movable member 22n and the second matching structure 50n mutually engaged under the elastic action of the first elastic member 21n, so as to achieve a locked state through the pressure of the second stacking member 40n. It should be noted that in this embodiment, the pressure refers to the gravity generated when the second stacking member 40n is placed.

[0209] In this way, during the stacking process, the second stacking member 40n only needs to be directly carried and placed on the first stacking member 10n, and the pressure generated by the weight of the second stacking member 40n can automatically form a locked state, which reduces the complexity of the locking operation and effectively improves the work efficiency and the convenience of stacking positioning. In other words, in this embodiment, the stacking hanging device 1000 can achieve gravity self-locking through the weight of the upper one.

[0210] Further, in the first embodiment of the utility model, the first movable member 22n is slidably connected to the first stacking member 10n. It can be understood that the sliding connection is convenient to operate and relatively stable. Optionally, the sliding direction of the first movable member 22n is consistent with the X direction or the Y direction. In other words, in the present embodiment, the first movable member 22n can slide toward the outside of the first stacking member 10n along the X direction or the Y direction of the first stacking member 10n. It should be emphasized that, in the present embodiment, the X direction refers to the length direction of the first stacking member 10n, the Y direction refers to the width direction of the first stacking member 10n, and the Z direction refers to the height direction of the first stacking member 10n.

[0211] Please see again Figures 39 to 50Optionally, in the present embodiment, the first movable member 22n can move along the X direction (length direction) of the first stacking member 10n; the first movable member 22n includes a base 221n and a first clamping portion 222n arranged on the base 221n, the base 221n can be slidably connected to the first stacking member 10n, and the second matching structure 50n includes a second clamping portion 51 arranged on the second stacking member 40n. In the locked state, the first clamping portion 222n can be mutually clamped with the second clamping portion 51 under the action of the first elastic member 21n, so as to at least limit the second stacking member from separating from the first stacking member along the Z direction.

[0212] It can be understood that the specific structures of the first clamping portion 222n and the second clamping portion 51 can be changed according to the needs to simultaneously restrict the second stacking member from moving relative to the first stacking member 10n in the X direction and / or the Y direction. Correspondingly, the third matching structure 30n and the fourth matching structure 60n can supplement the restriction of the movement of the second stacking member 40n in other directions to ensure that in the locked state, the first stacking member 10n and the second stacking member 40n cannot be relatively displaced in the three directions of X, Y, and Z.

[0213] It should be noted that, optionally, in this embodiment, the first clamping portion 222n is convexly provided on the base 221n, and the second clamping portion 51 is convexly provided on the bottom of the second stacking member 40n. It can be understood that the convexly provided is relative and does not mean that the entire surface of the base 221n or the bottom of the second stacking member 40n is protruded. The meaning of the convexly provided will not be repeated hereinafter, as long as the desired function can be achieved.

[0214] In this embodiment, the second clamping portion 51 may or may not protrude from the bottom of the second stacking member 40n, as long as the overall structure of the bottom of the second stacking member 40n does not affect the automatic gravity locking of the second stacking member 40n when it is stacked on the first stacking member 10n. For example, in this embodiment, a concave area (not numbered) may be provided at the bottom of the second stacking member 40n, and the second clamping portion 51 may protrude from the concave area but may not protrude from other parts of the bottom of the second stacking member 40n.

[0215] Please see again Figures 39 to 46 It can be understood that, in order to facilitate the engagement between the first card portion 222n and the second card portion 51, one of the first card portion 222n and the second card portion 51 may have a pin, and the other may have a slot 511, and the slot 511 may have one notch or multiple notches to selectively limit the movement direction of the second stacking member 40n according to requirements. In other words, different shapes of slots 511 and pins can be used to limit the movement of the second stacking member 40n in one or more directions.

[0216] For example, in this embodiment, the first clamping part 222n has a pin (not numbered), and the second clamping part 51 is provided with a slot 511; in the locked state, the pin of the first clamping part 222n can be inserted into the slot 511 under the action of the first elastic member 21n. Please refer to Figure 5 again. Further, in this embodiment, the slot 511 is a concave slot, that is, the slot 511 has only one notch, so that the side walls around the slot 511 can play a limiting role, wherein the upper and lower side walls of the slot 511 can limit the second stacking member 40n to move along the Z direction, and the left and right side walls of the slot 511 can limit the second stacking member 40n to move along the Y direction; the side wall of the slot 511 opposite to the notch can limit the second stacking member 40n to move along the X direction to the side away from the notch.

[0217] It is understandable that in other embodiments, the slot 511 may also have only upper and lower side walls, so that the movement of the second stacking member 40n along the Z direction can be selectively limited. Correspondingly, the movement of the second stacking member along the X direction and the Y direction can be limited by the third matching structure 30n and the fourth matching structure 60n.

[0218] Please see again Figures 39 to 50 In this embodiment, a movable groove 11n is provided on the top of the first stacking member 10n, and the movable groove 11n is used to install the first movable member 22n. The movable groove 11n has a first notch 111n and a second notch 112n that are connected to each other. The first notch 111n is provided on the side wall of the first stacking member 10n, and the second notch 112n is provided on the top wall of the first stacking member 10n. The first movable member 22n can move in the direction of the first notch 111n.

[0219] Please see again Figures 39 to 50 It should be noted that the side wall of the movable groove 11n opposite to the first notch 111n is the first side wall 113n, the two side walls opposite to the movable groove 11n are both the second side walls 114n, and the bottom wall opposite to the second notch 112n is the first bottom wall 115n. It can be understood that in this embodiment, the setting direction of the first elastic member 21n is toward the first side wall 113n, in other words, the setting direction of the first elastic member 21n is parallel to the length direction of the first stacking member 10n.

[0220] Furthermore, in this embodiment, the third matching structure 30n has the same structure as the first matching structure 20n and is arranged relative to each other, and the fourth matching structure 60n has the same structure as the second matching structure 50n and is arranged relative to each other. Such arrangement facilitates the rapid stacking and locking of the first stacking member 10n and the second stacking member 40n. Since the specific structures of the third matching structure 30n and the fourth matching structure 60n are the same as those of the first matching structure 20n and the second matching structure 50n, the matching process of the two will not be described in detail here.

[0221] Further, in one embodiment of the present invention, the second clamping portion 51 can be abutted against the first side wall 113n on the side opposite to the notch of the slot 511. In this way, the second clamping portion 51 of the second matching structure 50n and the second clamping portion 51 of the fourth matching structure 60n can cooperate with each other to ensure that the movement of the second stacking member 40n along the X direction is restricted, and ensure that in the locked state, after the first clamping portion 222n and the second clamping portion 51 are mutually engaged, the first stacking member 10n and the second stacking member 40n can be stably stacked and cannot be relatively separated in the X direction, the Y direction and the Z direction.

[0222] It can be understood that in other embodiments, the side of the second clamping portion 51 opposite to the slot 511 may not abut against the first side wall 113n, and the movement of the second stacking member 40n along the X direction may be relatively limited by other means; for example, an additional abutting protrusion is provided at the bottom of the second stacking member 40n corresponding to the first matching structure 20n and the third matching structure 30n, wherein the abutting protrusion corresponding to the first matching structure 20n can abut against the first side wall 113n of the movable groove 11n at the first matching structure 20n, and in the locked state, the abutting protrusion It is capable of limiting the movement of the second stacking member 40n in the direction approaching the third matching structure 30n in the X direction; further, in the locked state, the abutment protrusion corresponding to the third matching structure 30n can abut against the first side wall 113n of the movable groove 11n at the third matching structure 30n, and the abutment protrusion can limit the movement of the second stacking member 40n in the direction approaching the first matching structure 20n in the X direction; in this way, without relying on the second clamping portion 51, it is still possible to ensure that the movement of the first stacking member 10n and the second stacking member 40n in the X direction is effectively limited.

[0223] It can be understood that as long as the abutting protrusion can cooperate with the side wall of the movable groove 11n to limit the movement of the second stacking member 40n along the X direction, the setting position of the abutting protrusion can be flexibly changed, and can be set separately or integrated with other structures.

[0224] Please see again Figure 39 to Figure 41 , and see also Figures 47 to 55 , in order to facilitate the first movable member 22n to move under the gravity of the second stacking member 40n. Optionally, in this embodiment, the first clamping portion 222n has a first guiding slope 2221, and the first guiding slope 2221 is used to guide when the first clamping portion 222n is inserted into the slot 511. Specifically, the first guiding slope 2221 is arranged on a side of the first clamping portion 222n relatively away from the base 221n.

[0225] Further, the second clamping portion 51 has a second guiding slope 512, and the second guiding slope 512 is used for guiding when the first clamping portion 222n is inserted into the slot 511. Specifically, the second guiding slope 512 is arranged on a side of the second clamping portion 51 that is relatively far away from the second stacking member 40n. With such arrangement, in this embodiment, when the second stacking member 40n is placed on the first stacking member 10n, under the action of the gravity of the second stacking member 40n, the second guiding slope 512 of the second clamping portion 51 can cooperate with the first guiding slope 2221 of the first clamping portion 222n, so that the first clamping portion 222n can quickly enter the slot 511 to form a locked state.

[0226] In other words, when the second stacking member 40n is stacked and placed on the first stacking member 10n, the second clamping portion 51 can squeeze the first clamping portion 222n under the action of the gravity of the second stacking member 40n and the first guide slope 2221 and the second guide slope 512, so that the first movable member 22n can slide out of position on the first stacking member 10n, thereby enabling the second stacking member 40n to be stacked in place and fit together with the second stacking member 40n. After the second stacking member 40n is stacked in place, the first clamping portion 222n can be quickly inserted into the slot 511 under the elastic action of the first elastic member 21n, thereby realizing a complete locking process.

[0227] Please see again Figures 47 to 55 Optionally, in this embodiment, the base 221n is provided with two first clamping portions 222n, and the two first clamping portions 222n are arranged at intervals. Such a configuration can further increase the reliability of the clamping connection.

[0228] Please see again Figures 47 to 55 Optionally, in this embodiment, the first movable member 22n further includes an auxiliary portion 223n, which is disposed on the base 221n and located between the two first clamping portions 222n, and the auxiliary portion 223n is used to provide a force application position, so that it is convenient for the user to apply force to pull the first movable member 22n.

[0229] It can be understood that the auxiliary part 223n can be a convex edge part arranged on the base 221n, or other characteristic parts that can assist in pulling the base 221n to move, such as a groove part, or a silicone part or rubber part with a relatively rough surface.

[0230] Optionally, in this embodiment, two or three of the base 221n, the first clamping portion 222n, and the auxiliary portion 223n are integrally formed. This arrangement can facilitate processing.

[0231] Please see again Figures 39 to 46It should be noted that, in the first embodiment of the present invention, the first matching structure 20n is located in the middle of the width side of the first stacking member 10n, and it can be understood that the movement direction of the first movable member 22n is perpendicular to the width side. In other embodiments, the position of the first matching structure 20n can be set according to needs, and it can also be set on the length side, or not in the middle.

[0232] It can be understood that, according to requirements, the structure of the third matching structure 30n can be the same as that of the first matching structure 20n, or can be different from the structure of the first matching structure 20n.

[0233] Please see again Fig.47 and Fig.50 Furthermore, in this embodiment, the stacking device 1000 further includes a mounting seat 90, and the first elastic member 21n is mounted on the first stacking member 10n through the mounting seat 90. This can make the position of the first elastic member 21n more stable, thereby ensuring the stability of the sliding direction of the first movable member 22n.

[0234] Specifically, the mounting seat 90 is fixed on the first bottom wall 115n of the movable groove 11n. It can be understood that the mounting seat 90 can be integrally formed with the first bottom wall 115n, or can be independently formed and then installed on the first bottom wall 115n; further, the mounting seat is an L-shaped structure, including a first mounting plate attached to the first bottom wall 115n and a second mounting plate perpendicular to the first mounting plate. One end of the first elastic member 21n abuts against the second mounting plate of the mounting seat 90, and the other end abuts against the first movable member 22n, so that the first elastic member 21n can drive the first movable member 22n to move more stably.

[0235] Furthermore, in order to further ensure the installation stability of the first elastic member 21n and the sliding stability of the first movable member, a slide groove 225n is provided in the first movable member 22n, and the first elastic member 21n and the mounting seat 90 can be located in the slide groove 225n, so as to ensure that the mounting seat 90 and the slide groove 225n can cooperate with each other, so that the first elastic member 21n can drive the first movable member 22n to slide more stably and reliably. Exemplarily, in this embodiment, the slide groove 225n includes a first groove area and a second groove area connected to each other, the first groove area is used to accommodate the second mounting plate of the mounting seat 90, and the second groove area is used to accommodate the first mounting plate of the mounting seat 90 and the first elastic member 21n located on the first mounting plate, so as to ensure that the first movable member 22n can slide back and forth on the first bottom wall 115n.

[0236] In this embodiment, the two opposite side walls of the movable groove 11n are provided with a first limiting portion 1141, and the two corresponding sides of the first movable member 22n are provided with a second limiting portion 2212. The first limiting portion 1141 and the second limiting portion 2212 cooperate with each other to limit the moving distance or rotation range of the first movable member 22n.

[0237] In this embodiment, after the second stacking member 40n is stacked on the first stacking member 10n, the first movable member 22n can move on the first stacking member 10n and does not protrude from the side wall of the first stacking member 10n. This arrangement can avoid or reduce the risk of being unable to lock or unable to unlock after being locked due to the limited movement distance or range of the first movable member 22n in a narrow space.

[0238] It is understandable that in other embodiments, without affecting the mutual stacking and locking of the first stacking member 10n and the second stacking member 40n, after the second stacking member 40n is stacked onto the first stacking member 10n, the first movable member 22n may also move on the first stacking member 10n and protrude from the side wall of the first stacking member 10n.

[0239] Please see again Figure 39 to Figure 55 In this embodiment, the stacking and hanging device 1000 also includes an unlocked state. In the unlocked state, the second stacking member 40n can be separated from the first stacking member 10n; the stacking and hanging device 1000 also includes a positioning component 80. When the positioning component 80 is in the positioning position, the stacking and hanging device 1000 forms an unlocked state.

[0240] In this embodiment, the positioning assembly 80 is arranged on the first matching structure 20n. Under the action of external force, the first matching structure 20n can drive the positioning assembly 80 to move to the positioning position, so that the stacking device 1000 can switch from the locked state to the unlocked state. The positioning assembly 80 is arranged on the first matching structure 20n, so that the positioning assembly 80 and the first matching structure 20n can be kept synchronized, which is convenient for operation and can quickly form an unlocked state. It can be understood that in other embodiments, the positioning assembly 80 can also be arranged on the first stacking member 10n and / or the second stacking member 40n.

[0241] Furthermore, in this embodiment, the positioning assembly 80 includes a positioning member 81 and a second elastic member 82, the second elastic member 82 elastically acts on the positioning member 81, and the second stacking member 40n is also provided with a positioning matching portion 70. When the positioning assembly 80 follows the first movable member 22n to move to the positioning position, the positioning member 81 can be supported against the positioning matching portion 70 under the elastic action of the second elastic member 82 to prevent the first elastic member 21n from driving the first movable member 22n to move.

[0242] In this embodiment, the base 221n is provided with a first assembly groove 2211, and the positioning assembly 80 can be movably installed in the first assembly groove 2211; in the locked state, the positioning member 81 can rotate into the first assembly groove 2211 and compress the second elastic member 82 under the pressure of the positioning matching part 70; in the unlocked state, the first movable member 22n drives the positioning assembly 80 to move to the positioning position under the action of external force, and the positioning member 81 can be clamped on the positioning matching part 70 under the elastic action of the second elastic member 82 to prevent the first elastic member 21n from driving the base 221n to slide. It can be understood that the external force can be removed after the positioning assembly 80 reaches the positioning position. At this time, the positioning member 81 is clamped on the positioning matching part 70 under the elastic action of the second elastic member 82, so that the stacking device 1000 can be kept in the unlocked state, and the user can directly move the second stacking member 40n away from the first stacking member 10n.

[0243] Optionally, in this embodiment, the positioning and matching portion 70 is a protrusion 71 disposed at the bottom of the second stacking member 40n, and in the unlocked state, the positioning member 81 can elastically abut against the outer side of the protrusion 71 under the elastic action of the second elastic member 82. It can be understood that in other embodiments, the positioning and matching portion 70 can also be a side wall of the second stacking member 40n.

[0244] Optionally, in the present embodiment, the positioning member 81 has an inclined abutment surface 811 on the side opposite to the first bottom wall 115n of the first assembly groove 2211. When the first movable member 22n moves toward the outside of the first stacking member 10n, the inclined abutment surface 811 can facilitate the positioning member 81 to quickly reach the positioning position, so that the positioning member 81 can quickly abut against the positioning mating portion 70.

[0245] It can be understood that, in the locked state, the positioning fitting portion 70 can be pressed against the inclined abutting surface 811 to prevent the positioning member 81 from rotating out of the first assembly groove 2211 under the action of the second elastic member 82 .

[0246] Please see again Figure 51 to Figure 55 Optionally, in this embodiment, the side of the positioning member 81 abutting against the positioning matching portion 70 is an arcuate abutting surface 812. In this way, while ensuring the abutting positioning function, it is convenient for the positioning member 81 to rotate in the first assembly groove 2211. It can be understood that, correspondingly, in the unlocked state, the side of the positioning matching portion 70 and the positioning member 81 abutting against each other can also be an arcuate abutting surface. This further facilitates the abutting positioning of the two, and at the same time facilitates the positioning member 81 to rotate in the first assembly groove 2211.

[0247] Optionally, in this embodiment, a third limiting portion 2213 is provided on the arcuate abutting surface 812, and a fourth limiting portion 813 is provided on the groove wall of the first assembly groove 2211 corresponding to the arcuate abutting surface 812. When the positioning member 81 rotates in a direction away from the first bottom wall 115n of the first assembly groove 2211 under the elastic action of the second elastic member 82, the fourth limiting portion 813 can be blocked by the third limiting portion 2213. Such a configuration can maintain the stability of the positioning member 81 and prevent the positioning member 81 from being separated from the first assembly groove 2211.

[0248] Please see again Fig.55 Optionally, in this embodiment, the second elastic member 82 is a tower spring. The tower spring is small in size, has a large load and a strong variable stiffness, can be used in a small space, withstands greater pressure, and has a good shock-absorbing and rebound effect. It can be understood that in other embodiments, the second elastic member 82 includes but is not limited to a tower spring, a compression spring, a torsion spring, a spring sheet, etc.

[0249] It can be understood that a plurality of groups of matching components can be arranged on the top of the first stacking member 10n, each group of matching components can include one or more first matching structures 20n and one or more third matching structures 30n, and each group of matching components can position a second stacking member 40n. In other words, the first stacking member 10n can position a second stacking member 40n by forming a group of one or more first matching structures 20n and one or more third matching structures 30n, and the number and arrangement positions of the first matching structures 20n and the third matching structures 30n required for positioning a second stacking member 40n can be selected according to needs, so that second stacking members 40n of different sizes and / or different numbers can be fixed on the top of the first stacking member 10n.

[0250] It can be further understood that the number and setting positions of the second matching structures 50n and the fourth matching structures 60n on the second stacking component 40n do not necessarily completely correspond to the number and positions of the first matching structures 20n and the third matching structures 30n on the first stacking component 10n, and only need to correspond to the first matching structures 20n and the third matching structures 30n used to fix the second stacking component 40n.

[0251] Therefore, in actual mating, when the position of the first mating structure 20n for fixing the second stacking member 40n on the first stacking member 10n is determined, another or multiple structures on the first stacking member 10n that are mutually locked with the second stacking member 40n can be relatively formed as the third mating structure 30n.

[0252] It can be understood that the top of the first stacking member 10n and / or the second stacking member 40n can be flexibly arranged to fix the second stacking members 40n of different sizes accordingly by the first matching structure 20n and the third matching structure 30n.

[0253] Please see again Fig.40 Furthermore, in this embodiment, the stacking device 1000 also includes a reset state, in which the second stacking member 40n is separated from the first stacking member 10n, the first matching structure 20n is not subjected to force, and the position of the first matching structure 20n in the reset state is the same as the position of the first matching structure 20n in the locked state. It can be understood that in other embodiments, the position of the first matching structure 20n in the locked state may also be different from the position of the first matching structure 20n in the reset state, as long as the movement of the second stacking member 40n along the X, Y, and Z directions can be effectively restricted.

[0254] Please see again Figure 39 to Figure 55 , exemplarily, in this embodiment, the fifth matching structure 12n and the sixth matching structure 41 can cooperate with each other to limit the movement of the second stacking member in the X direction and the Y direction. Specifically, the fifth matching structure 12n includes a groove opened at the top of the first stacking member 10n, and the groove is located between the first matching structure 20n and the second matching structure 50n. The sixth matching structure 41 includes a card block arranged at the bottom of the second stacking member 40n, and the card block is located between the third matching structure 30n and the fourth matching structure 60n. When the second stacking member is stacked on the first stacking member, the card block can be stuck in the groove to limit the movement of the second stacking member 40n in the X direction and the Y direction. Such a setting can limit the movement of the second stacking member 40n in the X direction while strengthening the restriction on the movement of the second stacking member 40n in the Y direction. And it can ensure that the first stacking member 10n and the second stacking member 40n are more closely stacked, and can also be stably placed independently after separation.

[0255] In this embodiment, when the stacking member 1 is configured as a storage box, the storage box may be provided with a drawer (not shown) or a cabinet door (not shown) and other structures to facilitate the storage of items in the storage box or to take items out of the storage box. Optionally, the drawer is slidably mounted on one side of the storage box through a track structure. The specific structure of the cabinet door is not limited, and the opening direction of the cabinet door is not limited. It can be opened outwards to the left and right, or it can be pushed and pulled upward to open. The cabinet door can also be rotated to open and then slid to be stored on the top wall of the storage box. It will not be described in detail here.

[0256] In the present application, at least the outermost structure of the stacking member 1 is made of plastic material, which is easy to process as a whole and to form different structures according to different requirements, and can effectively reduce the overall cost of the stacking device. It is understood that in other embodiments, the stacking member 1 can also be made of metal structure as a whole, for example, the whole body is made of iron material. Iron material has high hardness, strong rigidity, and is not easy to damage.

[0257] Further, it can be understood that when the inventive concept and other structures are the same as the first embodiment of the stacking connection between the stacking members 1 of the present application, in other embodiments, the first elastic member 21n can also be connected to one of the second side walls 114n of the movable groove 11n, and the sliding direction of the first movable member 22n is the same as the width direction of the first stacking member 10n, that is, the first movable member 22n can slide along the Y direction.

[0258] See also Figure 56 to Figure 62 The second embodiment of the stacking connection between the stacking members 1 of the present application, the inventive concept and most of the structures of the second embodiment are the same as those of the first embodiment of the stacking connection between the stacking members 1, the difference being that in the second embodiment, the first movable member 22n is rotatably connected to the first stacking member 10n.

[0259] In the third embodiment, the first movable member 22n includes a rotating seat 224n and a first clamping portion 222n arranged on the rotating seat 224n, the rotating seat 224n is rotatably connected to the first stacking member 10n, and the second matching structure 50n includes a second clamping portion 51 arranged on the second stacking member 40n, and the second clamping portion 51 is provided with a slot 511; in the locked state, the first clamping portion 222n can be inserted into the slot 511 under the elastic action of the first elastic member 21n to limit the second stacking member 40n from disengaging from the first stacking member 10n along the X direction, the Y direction and the Z direction.

[0260] Furthermore, the rotating seat 224n is provided with a second assembly groove 2241, and the positioning component 80 can be movably installed in the second assembly groove 2241; in the locked state, the positioning member 81 can be located on the side of the positioning matching portion 70 relatively away from the second stacking member 40n; in the unlocked state, the first movable member 22n drives the positioning component 80 to move to the positioning position under the action of external force, and the positioning member 81 can abut against the positioning matching portion 70 under the elastic action of the second elastic member 82 to prevent the first elastic member 21n from driving the rotating seat 224n to rotate.

[0261] See also Figure 56-Figure 62 In the present embodiment, the positioning fitting portion 70 is a foot 72 disposed at the bottom of the second stacking member 40n, and the foot 72 includes a connecting portion 721 and a hook portion 722 disposed at the bottom end of the connecting portion 721; in the unlocked state, the positioning member 81 can be driven by the rotating seat 224n to be locked against a side of the hook portion 722 relatively close to the second stacking member 40n.

[0262] Furthermore, the hook portion 722 has a third guide slope 7221 on a side relatively away from the second stacking member 40n. When the unlocking state is formed, the third guide slope 7221 is used to guide when the rotating seat 224n drives the positioning member 81 to rotate. In other words, when unlocking is required, the third guide slope 7221 can facilitate the rotating member to drive the positioning member 81 to rotate to the positioning position to prevent the first elastic member 21n from driving the first clamping portion 222n of the rotating member to be inserted into the slot 511 of the second matching structure 50n.

[0263] Furthermore, the hook portion 722 has a fourth guide slope 7222 on one side relatively close to the second stacking member 40n. When the unlocked state is formed, the fourth guide slope 7222 is used to guide the second stacking member 40n when it moves in the direction of separating from the first stacking member 10n. In other words, the fourth guide slope 7222 can prevent the hook portion 722 and the bottom of the positioning member 81 from blocking each other, so that the second stacking member 40n can quickly move in the direction of separating from the first stacking member 10n.

[0264] See also Figures 63 to 71 Furthermore, in the third embodiment of the stacking connection between the stacking members 1 of the present application, the inventive concept and most of the structures of the third embodiment are the same as those of the first embodiment of the stacking connection between the stacking members 1, except that the first movable member 22n can be rotatably connected to the first stacking member 10n.

[0265] In the third embodiment, the first movable member 22n includes a rotating seat 224n and a first clamping portion 222n arranged on the rotating seat 224n, the rotating seat 224n is rotatably connected to the first stacking member 10n, and the second matching structure 50n includes a second clamping portion 51 arranged on the second stacking member 40n, and the second clamping portion 51 is provided with a slot 511; in the locked state, the first clamping portion 222n can first rotate in the γ direction under the pressure of the second stacking member 40n. At this time, the first elastic member 21n is elastically compressed by the pressure of the rotating seat 224n. After the second stacking member 40n is stacked in place, the elastic restoring force of the first elastic member 21n causes the rotating seat 224n to rotate and reset in a direction close to the second clamping portion 51, thereby causing the first clamping portion 222n to be inserted into the slot 511 to limit the second stacking member 40n from disengaging from the first stacking member 10n along the X direction, the Y direction and the Z direction.

[0266] See also Figures 67 to 71Specifically, in this embodiment, the rotating seat 224n includes a clamping body 2242, a support body 2243 and a swivel support leg 2244, one end of the support body 2243 is connected to one side of the clamping body 2242, and the first clamping portion 222n is connected to one end of the clamping body 2242. One end of the clamping body 2242 relatively far from the first clamping portion 222n is an eaves body portion 22421, and the eaves body portion 22421 and the first clamping portion 222n are respectively located on two sides of the support body 2243 that are relatively far away from each other, and the swivel support leg 2244 is connected to one end of the support body 2243 relatively far from the clamping body 2242, and the swivel support leg 2244 and the first clamping portion are located on the same side of the support body 2243.

[0267] A movable groove 11n is provided at the top of the first stacking member 10n, and the movable groove 11n is used to install the first movable member 22n. The movable groove 11n has a first slot 111n and a second slot 112n which are connected to each other. The first slot 111n is provided on the side wall of the first stacking member 10n, and the second slot 112n is provided on the top wall of the first stacking member 10n. The clamping body 2242 can rotate toward the side of the first slot 111n relatively away from the second slot 112n with the swivel leg 2244 as the rotation point.

[0268] Further, the side wall of the movable groove 11n opposite to the first notch 111n is the first side wall 113n, the two side walls opposite to the movable groove 11n are both the second side wall 114n, and the bottom wall opposite to the second notch 112n is the first bottom wall 115n. It can be understood that in this embodiment, the first elastic member 21n is clamped between the eaves body portion 22421 and the first stacking member 10n, and the setting direction of the first elastic member 21n is toward the first bottom wall 115n. In other words, the setting direction of the first elastic member 21n is perpendicular to the first bottom wall 115n.

[0269] Furthermore, a foot slot 1131 is formed on the first side wall 113n, and a swivel foot 2244 of the swivel seat 224n is inserted into the foot slot 1131. The swivel foot 2244 can be supported and rotated in the foot slot 1131 to ensure the rotation stability of the swivel seat 224n.

[0270] See also Figures 67 to 71 Furthermore, the first stacking member 10n is also provided with a seat body limiter 13n, which is fixed on the first bottom wall 115n and located between the rotating seat 224n and the first bottom wall 115n. The seat body limiter 13n is used to limit the movement of the rotating seat 224n in a direction away from the first side wall 113n, that is, to limit the rotating seat 224n from escaping from the movable groove 11n.

[0271] See also Fig.71, exemplarily, the seat body stopper 13n includes a base portion 131n fixedly connected to the first bottom wall 115n and a stopper portion 132n protruding from the side of the base portion 131n away from the first side wall 113n, and the rotating seat 224n is rotatably disposed on the base portion 131n and located between the stopper portion 132n and the first side wall 113n. In other words, the rotating seat 224n is limited by the stopper portion 132n and the leg slot 1131 when translated in the X direction.

[0272] Furthermore, the blocking body 132n is further provided with a receiving groove 1321, and the first elastic member 21n is disposed in the receiving groove 1321. In order to ensure the stability of the first elastic member 21n, a sleeve column 1322 is further protruded from the bottom of the receiving groove 1321, and the first elastic member 21n is partially sleeved on the sleeve column 1322.

[0273] In this embodiment, the positioning assembly 80 is disposed on the second stacking member 40n. Under the action of an external force, the positioning assembly 80 can move to a positioning position so that the stacking device 1000 can switch from a locked state to an unlocked state.

[0274] Specifically, the positioning assembly 80 includes a positioning member 81, which is rotatably connected to the second stacking member 40n. The positioning member 81 has a first arm 814 and a second arm 815 with opposite rotation directions. The first arm 814 can rotate to a positioning position under the action of an external force, and drive the second arm 815 to act in the opposite direction on the first movable member 22n, so that the first movable member 22n rotates out of the second matching structure 50n, thereby switching the stacking device 1000 from a locked state to an unlocked state.

[0275] The positioning assembly 80 also includes a third elastic member 83, which is arranged between the first arm 814 and the second stacking member 40n, and elastically acts on the first arm 814; when the stacking device switches from a locked state to an unlocked state, the third elastic member 83 can be compressed by the first arm 814, and after the second stacking member 40n is separated from the first stacking member 10n, it drives the positioning member 81 to reset.

[0276] See also Figures 63 to 71 In this embodiment, a rotational installation slot 42 is further provided at the bottom of the second stacking member 40n, and the positioning member 81 is rotatably installed in the rotational installation slot 42. The rotational installation slot 42 has a third slot 421 and a fourth slot 422. The third slot 421 is provided in the side wall of the second stacking member 40n, and the fourth slot 422 is provided in the bottom wall of the second stacking member 40n. The side wall of the rotational installation slot 42 opposite to the third slot 421 is the third side wall 423, and the two side walls opposite to the rotational installation slot 42 are both the fourth side wall 424, and the bottom wall opposite to the fourth slot 422 is the second bottom wall (not shown).

[0277] The connection between the first arm 814 and the second arm 815 is hinged between the two fourth side walls 424 of the rotation installation slot 42, and the third elastic member 83 is disposed between the first arm 814 and the second bottom wall. In the locked state and the reset state, the second arm 815 is parallel to the third side wall 423, and there is a rotation gap (not shown) between the first arm 814 and the second bottom wall, and the rotation gap is used to make way so that the first arm 814 can rotate normally after being subjected to force.

[0278] Further, in order to facilitate the positioning member 81 to drive the rotating seat 224n to rotate to form an unlocked state, in this embodiment, the first clamping portion 222n of the rotating seat 224n is further provided with an abutting groove 2222, and the end of the second arm 815 away from the first arm 814 is further provided with an abutting foot 8151, and when the second stacking member 40n and the first stacking member 10n are stacked to form a locked state, the abutting foot 8151 can be accommodated in the abutting groove 2222. When switching from the locked state to the unlocked state, the user bends the first arm 814 upward, that is, the first arm 814 is rotated toward the side of the second bottom wall (see the α direction in the figure), the third elastic member 83 is compressed, and the second arm 815 is rotated in the opposite direction (see the β direction in the figure), and the abutting foot 8151 of the second arm 815 will rotate along the β direction, and push the rotating seat 224n to rotate through the abutting groove 2222, so that the first clamping portion is disengaged from the slot 511 of the second stacking member 40n. It should be noted that during this process, the user needs to continuously apply force to the first arm 814, so that the first arm 814 first rotates to the positioning position, and then remains in the positioning position until the second stacking member 40n is completely separated from the first stacking member 10n. In the first embodiment, the second embodiment and the third embodiment, after the user pulls the first movable member 22n to drive the positioning assembly 80 to reach the positioning position, the positioning member 81 can be stopped against the positioning matching portion 70 under the action of the second elastic member. Therefore, after the positioning member 81 reaches the positioning position, the user can no longer apply force to the first movable member 22n, but keep the positioning member 81 in the positioning position through the positioning matching portion 70 until the second stacking member 40n is moved away from the first stacking member 10n. It should be noted that the "positioning position" refers to the position and state of the positioning member 81 when the first arm 814 rotates to abut against the second bottom wall.

[0279] See also Figures 63 to 71Furthermore, in order to improve the rotation stability of the rotating seat 224n, in this embodiment, the seat limiter 13n is further provided with two side auxiliary walls 133n arranged opposite to each other, and the two side auxiliary walls 133n are convexly arranged on the side of the base 131n away from the first bottom wall 115n. A connecting hole 1331 is provided on the side auxiliary wall 133n, and arc-shaped grooves 22431 are respectively provided on the two opposite sides of the support body 2243. The first stacking member 10n also includes an auxiliary shaft (not shown), one end of which is connected to the connecting hole, and the other end of which can slide in the arc-shaped groove 22431. When the rotating seat 224n rotates along the γ direction with the rotating body support leg 2244 as a fulcrum, so that the first clamping part 222n is separated from the slot 511, the auxiliary shaft can cooperate with the arc-shaped groove to assist the rotating seat 224n in rotating, so as to prevent the rotating seat 224n from shaking along the Y direction during the rotation process.
