DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] like Figure 1-Figure 13 As shown, the embodiment of the present application provides a locking assembly for connecting the adjacent first box body 100 and the second box body 200, so that the connection state of the first box body 100 and the second box body 200 includes a locked state and an unlocked state. When the first box body 100 and the second box body 200 are in the locked state, they are connected together and cannot be separated. When the first box body 100 and the second box body 200 are in the unlocked state, the connection is cancelled and can be separated. The first box body 100 and the second box body 200 are adjacent, for example, the first box body 100 and the second box body 200 are stacked up and down, or the first box body 100 and the second box body 200 are abutted left and right.

[0054] The locking assembly includes a locking structure and a retaining structure, and the locking structure and the retaining structure are both arranged on the adjacent first box body 100 and the second box body 200. For example, the first box body 100 and the second box body 200 are stacked up and down, and the locking structure and the retaining structure are both arranged at the bottom of the first box body 100 and the top of the second box body 200. In other embodiments, the retaining structure may also be arranged only on the first box body 100 or the second box body 200.

[0055] The lock structure has a locked state and an unlocked state. When the lock structure is in the locked state, the lock structure cannot be arranged along the direction of the first box body 100 and the second box body 200 (this direction is defined as the first direction in this article, i.e. Figure 7 or Fig.11 When the locking structure is in the unlocked state, the locking structure can move along the first direction to separate the first box body 100 and the second box body 200, that is, it is in the unlocked state.

[0056] The holding structure is linked with the locking structure, that is, the holding structure can move synchronously with the locking structure. Here, the locking structure can move in a direction perpendicular to the arrangement direction of the first box body 100 and the second box body 200 (this direction is defined as the second direction in this article, that is, Figure 7 or Fig.11The locking structure is moved in the Y direction in the middle for accurate description) so that the locking structure switches between the locked state and the unlocked state, and the retaining structure can move along the second direction with the locking structure. When the locking structure moves to the unlocked state, the retaining structure keeps the locking structure in the unlocked state to limit the locking structure from moving along the second direction to the locked state. In this embodiment, the displacement direction of the retaining structure is perpendicular to the displacement direction of the locking structure; in other embodiments, the displacement direction of the retaining structure is different from the unlocking direction of the locking structure to achieve the function of the retaining structure keeping the locking structure in the unlocked state.

[0057] The holding structure has a first blocking portion and a second blocking portion 20. When the lock structure moves along the second direction to the unlocked state, the first blocking portion and the second blocking portion 20 in the holding structure abut against each other in the second direction, thereby limiting the movement of the lock structure, so that the lock structure remains in the unlocked state. Since the first blocking portion and the second blocking portion are both planes, the abutment effect can be made more reliable, thereby improving the structural stability of the holding structure, so that the lock structure can be safely and stably maintained in the unlocked state.

[0058] It should be noted that when the first blocking portion and the second blocking portion abut against each other in the second direction, the first blocking portion and the second blocking portion cannot pass through each other without the action of external force. For example, the first blocking portion and the second blocking portion 20 are both set as straight surfaces perpendicular to the unlocking direction (i.e., the second direction) of the lock structure, and the blocking is performed in the form of two straight surfaces abutting against each other; or, one or both of the first blocking portion and the second blocking portion are set as inclined surfaces or curved surfaces, and the blocking is performed in the form of straight surfaces abutting against inclined surfaces, or inclined surfaces abutting against inclined surfaces.

[0059] With such a configuration, the locking structure is maintained in an unlocked state by the retaining structure, and the first box body 100 and the second box body 200 can be separated without applying a retaining force to the lock structure, which is conducive to the rapid disassembly of the assembled storage box, is simple to operate, and saves time and effort.

[0060] In some embodiments, the first box body 100 is arranged on the top of the second box body 200, so that the first box body 100 and the second box body 200 are stacked up and down. The locking structure includes an operating member 2, a locking member 3 and a locking groove 10, wherein the operating member 2 is arranged on the first box body 100 and can be displaced along the second direction relative to the first box body 100, for example, the first box body 100 is provided with a sliding groove or a sliding hole extending along the second direction, and the operating member 2 is slidably arranged in the sliding groove or the sliding hole; the locking member 3 is linked with the operating member 2, so that the locking member 3 can be displaced along the second direction with the operating member 2, and the locking member 3 protrudes from the bottom of the first box body 100. The locking member 3 is provided at the bottom of the first box body 100 so as to extend into the locking groove 10. For example, a sliding groove or a sliding hole for the locking member 3 to protrude is provided at the bottom of the first box body 100. The locking groove 10 is provided on the second box body 200 and protrudes from the top of the second box body 200. For example, when the first box body 100 and the second box body 200 are close to each other, the bottom of the first box body 100 abuts against the side wall of the locking groove 10, and the protruding locking member 3 is opposite to the notch of the locking groove 10, so that the locking member 3 can extend into the locking groove 10.

[0061] When the lock structure is in a locked state, the locking member 3 is located in the locking groove 10, and the locking groove 10 prevents the locking member 3 and the operating member 2 from being displaced along the first direction, that is, the lock structure cannot move along the first direction; when the lock structure is in an unlocked state, the locking member 3 is located outside the locking groove 10, and the locking member 3 allows the locking member 3 and the operating member 2 to be displaced along the first direction, that is, the lock structure can move along the first direction.

[0062] It should be noted that the locking groove 10 can prevent the locking member 3 from being displaced along the first direction. For example, the inner side wall of the locking groove 10 away from the second box body 200 is set as a straight surface perpendicular to the first direction. The locking member 3 is located in the portion of the locking groove 10, and the side wall away from the second box body 200 is also set as a straight surface perpendicular to the first direction. The two straight surfaces abut against each other to limit the displacement of the locking member 3 relative to the locking groove 10 along the first direction. For example, the end of the locking member 3 away from the operating member 2 is set in the form of a barb.

[0063] In this way, the locking member 3 and the operating member 2 in the locking structure are both arranged at the bottom of the first box body 100, and only the locking groove 10 is arranged at the top of the second box body 200. For a large combined storage box, a pulley is arranged at the bottom of the lowermost box body, and a locking structure is not required at the bottom of the lowermost box body. Compared with the traditional solution in which the lock is arranged at the upper cover position of the box body, there is one less locking component, which is conducive to reducing costs.

[0064] In some preferred embodiments, a sliding groove is provided at the bottom of the first box body 100, and the sliding groove extends inward from the bottom edge of the first box body 100 along the second direction to form a form in which one end is open and the other end is closed. The operating member 2 is arranged in the sliding groove through a guide structure so that the operating member 2 can slide and displace in the sliding groove along the second direction, wherein the guide structure may include a guide rail arranged between the operating member 2 and the sliding groove. Moreover, a fixing member 1 is provided at the open end of the sliding groove, and the fixing member 1 is fixed in the sliding groove and is flush with the bottom edge of the first box body 100, which can not only ensure that the outer contour of the first box body 100 is beautiful to cover the traces of matching at various places, but also protect the operating member 2 in the sliding groove, thereby limiting the operating member 2 in the sliding groove, and facilitating the installation of the locking structure on the first box body 100. The fixing member 1 can be integrally formed with the box body, or can be detachably connected to the box body by connecting methods such as rivets and mortise and tenon joints.

[0065] like Figure 5 As shown, the guide structure includes a guide tube 5 and a guide groove 202, wherein the guide tube 5 is arranged in the sliding groove and connected to the first box body 100, for example, the guide tube 5 is suspended in the sliding groove, or fixed to the side wall of the sliding groove; the guide groove 202 is arranged on the operating member 2, and is slidably matched with the outer wall of the guide tube 5, so that the guide groove 202 can slide and displace along the extension direction of the guide tube 5, thereby guiding the operating member 2. Here, the extension directions of the guide tube 5 and the sliding groove are both in the second direction, thereby guiding the operating member 2 in the second direction.

[0066] Moreover, a second elastic member 4 is arranged in the guide tube 5, for example, the second elastic member 4 is arranged as a spring, and the two ends of the spring are respectively against the bottom of the guide groove 202 and the first box body 100. Under the elastic force of the spring, the second elastic member 4 can drive the operating member 2 to move in the direction away from the guide tube 5, that is, the operating member 2 is displaced along the second direction, and the locking member 3 is extended into the locking groove 10. In this way, through the arrangement of the second elastic member 4, the locking member 3 can be pressed tightly in the locking groove 10 by the elastic force, thereby improving the locking effect of the lock structure. At the same time, the second elastic member 4 is arranged in the guide tube 5, which can save the occupied volume and improve the elastic stability of the second elastic member 4.

[0067] The fixing member 1 is provided with a through hole 101, for example, the through hole 101 is provided in the middle of the fixing member 1, so that the fixing member 1 forms a frame shape. The operating member 2 is provided with a button portion 201 protrudingly, and the button portion 201 is located on a side of the operating member 2 close to the fixing member 1. When the operating member 2 approaches the fixing member 1, the button portion 201 gradually extends into the through hole 101 until the button portion 201 is exposed from the fixing member 1. In this way, when operating the operating member 2, the exposed button portion 201 can be pressed, and the operation is simple.

[0068] In some other preferred embodiments, a sliding cavity is provided on the first box body 100, the sliding cavity is provided at the bottom edge of the first box body 100, and is extended along the edge, and the operating member 2 is provided in the sliding cavity and is slidably provided along the extension direction of the sliding cavity. For example, a bearing groove is provided on the side of the first box body 100, the groove bottom of the bearing groove is close to the second box body 200, the groove opening of the bearing groove is far away from the second box body 200, the operating member 2 is provided in the bearing groove, and the groove opening of the bearing groove is closed with a cover plate to form a sliding cavity for the position-limiting operating member 2.

[0069] Among them, a side wall (i.e., bottom wall) of the sliding cavity close to the second box body 200 is provided with an opening, so that the locking member 3 passes through and protrudes from the sliding cavity, and then cooperates with the locking groove 10 on the second box body 200. An operating portion 203 (such as a handle) is provided on the operating member 2, and a side wall (i.e., cover plate) of the sliding cavity away from the second box body 200 is provided with an opening, or the size of the cover plate is smaller than the slot size of the bearing groove to form an opening, and the operating portion 203 passes through the opening and protrudes from the sliding cavity, so as to operate the operating member 2 and cause the operating member 2 to move along the second direction.

[0070] In addition, a second elastic member 4, such as a compression spring or a torsion spring, is disposed in the sliding cavity. The second elastic member 4 is disposed between the operating member 2 and the end of the sliding cavity, and is used to drive the operating member 2 to reset, so that the operating member 2 drives the locking member 3 to extend into the locking groove 10.

[0071] In some embodiments, the retaining structure includes a retaining member 6, a stop block 9 and a first elastic member 7, wherein the retaining member 6 is arranged on the operating member 2, the operating member 2 can drive the retaining member 6 to move, and the retaining member 6 moves along an action direction different from the operating member 2; specifically, the retaining member 6 can move relative to the operating member 2 along a first direction and a first blocking portion is provided on the retaining member 6, for example, a slide groove or a slide hole extending along the first direction is provided on the operating member 2, and the retaining member 6 is slidably arranged in the slide groove or the slide hole; the stop block 9 is arranged at the top of the second box body 200, and a second blocking portion 20 is provided on one side of the stop block 9, the second blocking portion 20 can block the retaining member 6 from moving in the second direction, and when the first blocking portion of the retaining member 6 is against the second blocking portion 20, the second blocking portion 20 can block the retaining member 6 from moving in the second direction; the first elastic member 7 is arranged between the retaining member 6 and the operating member 2, and the first elastic member 7 can drive the retaining member 6 to move relative to the operating member 2 along the first direction and approach the second box body 200.

[0072] The retainer 6 and the stop block 9 are slidably matched by the first inclined surface 17, and the first inclined surface 17 is arranged on the retainer 6 and / or the stop block 9, that is, at least one of the retainer 6 and the stop block 9 is provided with the first inclined surface 17, and the retainer 6 and the stop block 9 are both provided with the first inclined surface 17, so that the first inclined surface 17 of the retainer 6 abuts against the first inclined surface 17 of the stop block 9 in the second direction. Specifically, the end of the retainer 6 away from the operating member 2 is set as a locking tongue, and the stop block 9 is set as a wedge. In the unlocking process of the lock structure, the locking member 3 gradually moves along the second direction and away from the locking groove 10, and the retainer 6 gradually moves along the second direction and away from the locking groove 10, and under the sliding cooperation of the first inclined surface 17, the retainer 6 gradually moves along the first direction and away from the second box body 200. When the retaining member 6 passes over the stop block 9 and the second blocking portion 20 on the stop block 9, the first elastic member 7 drives the retaining member 6 to move in the first direction and approach the second box body 200 until the retaining member 6 abuts against the top of the second box body 200. At this time, under the action of the second blocking portion 20, the retaining member 6 cannot move in the second direction and approach the locking groove 10, and the locking member 3 cannot move in the second direction and approach the locking groove 10, thereby keeping the locking member 3 outside the locking groove 10, so that the locking structure is kept in an unlocked state through the retaining structure.

[0073] In this way, by setting the stopper 6 in the retaining structure, the locking structure is kept in an unlocked state, so that the first box body 100 and the second box body 200 are separated along the first direction, and after the first box body 100 and the second box body 200 are separated, under the action of the second elastic member 4, the locking structure automatically returns to its position, so as to facilitate the next locking, further facilitating the assembly of adjacent box bodies.

[0074] like Figure 7 As shown, the operating member 2 is provided with a mounting groove 19, the extending direction of the mounting groove 19 is the first direction, the retaining member 6 and the first elastic member 7 are both provided in the mounting groove 19, for example, the first elastic member 7 is provided as a spring and abuts between the groove bottom of the mounting groove 19 and the retaining member 6, and is used to drive the retaining member 6 to extend out of the mounting groove 19 by its own elastic force. Moreover, one end of the retaining member 6 close to the groove bottom of the mounting groove 19 is provided as a widened portion, and a limiting pin 8 is provided in the mounting groove 19 to form a limiting structure, and the limiting pin 8 is used to limit the widened portion of the retaining member 6 from extending out of the mounting groove 19. For example, the limiting pin 8 is located in the mounting groove 19 and extends along the second direction, so that the inner diameter of the corresponding position of the mounting groove 19 with the limiting pin 8 is smaller than the outer diameter of the widened portion and larger than the outer diameter of the main body of the retaining member 6. Under the action of the first elastic member 7, the widened portion of the retaining member 6 abuts against the limiting pin 8, thereby limiting the maximum volume of the retaining member 6 extending out of the mounting groove 19. In this way, the retaining member 6 is limited in the installation groove 19 through the matching design of the limiting pin 8 and the widened portion, and the structure is simple and stable, and the installation is convenient.

[0075] In some other embodiments, the holding structure includes a holding member 6, a stop hole 21 and a first elastic member 7, wherein the holding member 6 is arranged on the operating member 2 and can be displaced along a first direction relative to the operating member 2, and a first blocking portion is arranged on the holding member 6, for example, a slide groove or a slide hole extending along the first direction is arranged on the operating member 2, and the holding member 6 is slidably arranged in the slide groove or the slide hole; the first elastic member 7 is arranged between the holding member 6 and the operating member 2, and the first elastic member 7 can drive the holding member 6 to displace along the first direction relative to the operating member 2 and approach the second box body 200. The stop hole 21 is arranged at the top of the second box body 200, and one side of the stop hole 21 is arranged as a second blocking portion 20, and when the second blocking portion 20 abuts against the first blocking portion on the holding member 6, the second blocking portion 20 can block the holding member 6 from displacing along the second direction, thereby locking the locking structure in an unlocked state.

[0076] In the process of unlocking the lock structure, the retaining member 6 abuts against the top of the second box body 200 and slides along the top of the second box body 200. When the lock structure is in the unlocked state, the retaining member 6 is opposite to the stop hole 21, and the first elastic member 7 can drive the retaining member 6 to move along the first direction, so that the retaining member 6 extends into the stop hole 21, and then the first blocking portion on the retaining member 6 abuts against the second blocking portion 20 in the stop hole 21 in the second direction.

[0077] like Fig.11 , 12 As shown, the operating member 2 is provided with a mounting groove 19, the extending direction of the mounting groove 19 is the first direction, the retaining member 6 and the first elastic member 7 are both provided in the mounting groove 19, for example, the first elastic member 7 is provided as a spring and abuts between the groove bottom of the mounting groove 19 and the retaining member 6, and is used to drive the retaining member 6 to extend out of the mounting groove 19 through its own elastic force. Moreover, one end of the retaining member 6 close to the groove bottom of the mounting groove 19 is provided as a widened portion, and a limiting structure is provided at the notch of the mounting groove, and the widened portion is limited in the mounting groove by the limiting structure, and only the non-widened portion of the retaining member close to the second box body 200 is allowed to extend out of the mounting groove.

[0078] In combination with the above-mentioned solution of the sliding cavity, the limiting structure is arranged in an opening on the bottom wall of the sliding cavity, and the size of the opening is smaller than the size of the widened portion of the retaining member to limit the widened portion from extending out of the mounting groove.

[0079] Further, the retainer is provided with a convex portion 61, for example, the convex portion 61 is provided as a convex strip on one side of the retainer, the mounting groove and the side wall of the first box body are provided with a window 23, the convex portion 61 protrudes from one side of the retainer and is located in the window 23, so that the convex portion 61 is exposed through the window 23. The convex portion 61 can be displaced in the window 23, so that the first blocking portion and the second blocking portion abut and misalign, for example, when the convex portion 61 is located at the lower part of the window 23, the first blocking portion and the second blocking portion abut, and when the convex portion 61 is located at the upper part of the window 23, the first blocking portion and the second blocking portion are misaligned, so that the retainer extends out of the stop hole 21. After the retaining structure keeps the lock structure in the unlocked state, if it is no longer necessary to separate the first box body and the second box body, the convex portion 61 can be toggled in the window 23, and the retainer is driven to displace along the first direction through the convex portion 61, so that the retainer extends out of the stop hole 21, and then the lock structure can be moved along the second direction to the locked state.

[0080] In combination with the above-mentioned sliding cavity solution, a slot is provided on the side wall of the mounting groove, and an opening is provided on the side wall of the sliding cavity. The slot and the opening are located opposite to each other to form a window 23 for exposing the protrusion 61.

[0081] In some preferred embodiments, a plurality of locking members 3 are provided, and can be integrally formed and arranged on the operating member 2, for example, two, three, or four locking members 3 are arranged at intervals. In this way, the form of multiple locking members 3 cooperating with the locking groove 10 can improve the balance and stability of the locking. Among them, the retaining member 6 is provided between two adjacent locking members 3, the retaining member 6 and the locking member 3 can be kept on the same straight line, and the moving path of the retaining member 6 is perpendicular to the moving path of the locking member 3, and can not interfere with each other. In the process of unlocking the lock structure, when the locking member 3 and the retaining member 6 are synchronously displaced with the operating member 2, the locking member 3 will not collide with the stop block 9.

[0082] The top of the second box body 200 is provided with a first protrusion 11 and a second protrusion 12, which are respectively located at two opposite edges of the second box body 200. When the first box body 100 and the second box body 200 are locked, the bottom of the first box body 100 abuts against the first protrusion 11 and the second protrusion 12.

[0083] The inner side wall of the first protruding portion 11 (i.e., the side wall close to the second protruding portion 12) is provided with the above-mentioned locking groove 10, and the opening direction of the locking groove 10 is toward the second protruding portion 12. The inner side wall of the second protruding portion 12 (i.e., the side wall close to the first protruding portion 11) is provided with the above-mentioned clamping groove 16, and the opening direction of the clamping groove 16 is toward the first protruding portion 11. In this way, by providing the first protruding portion 11 and the second protruding portion 12, the locking groove 10 and the clamping groove 16 can be stably supported, thereby improving the locking stability of the lock structure and the clamping stability of the clamping structure. In other embodiments, the opening of the second protruding portion 12 is toward the first protruding portion 11, and the opening of the first protruding portion 11 is toward the side away from the second protruding portion 12.

[0084] Alternatively, a stop hole 21 and a locking hole 22 are provided at the top of the first protrusion, a locking groove is provided on the side wall of the locking hole 22, and the locking member of the locking structure can extend into the locking hole 22. The locking member can extend into and out of the locking groove by displacement along the second direction.

[0085] In some embodiments, the locking assembly includes a buckle structure, which is disposed on the first box body 100 and the second box body 200. The buckle structure can limit the separation of the first box body 100 and the second box body 200 along the first direction. Moreover, the buckle structure and the lock structure are respectively located at two opposite edges of the first box body 100 or the second box body 200. When the first box body 100 and the second box body 200 are locked, one side of the first box body 100 and the second box body 200 is buckled by the buckle structure, and the other side is locked by the lock structure. When the first box body 100 and the second box body 200 need to be separated, only the lock structure needs to be unlocked, which is conducive to simplifying the structure of the locking assembly and facilitating the disassembly and assembly operation.

[0086] The buckle structure includes a card slot 16 and a card block 15. The card slot 16 is arranged on the second box body 200 and protrudes from the top of the second box body 200. The card block 15 is arranged on the first box body 100 and protrudes from the bottom of the first box body 100. When the first box body 100 and the second box body 200 are locked, the bottom of the first box body 100 abuts against the side wall of the card slot 16 away from the second box body 200, and the card block 15 is located in the card slot 16, so that the card slot 16 limits the card block 15 to move in the first direction and away from the second box body 200, thereby allowing the buckle structure to limit the first box body 100 and the second box body 200 to separate in the first direction. In this way, the buckle structure is simple and reliable, which is conducive to cost saving. In this embodiment, the buckle structure can be arranged at the edge of the second box body 200; in other embodiments, the buckle structure can also be arranged at other positions of the second box body 200.

[0087] It should be noted that the opening direction (locking direction) of the locking groove 10 in the locking structure is opposite to the opening direction (locking direction) of the card slot 16 in the snap structure, so as to limit the relative displacement of the first box body 100 and the second box body 200 along the second direction, thereby improving the locking stability of the locking assembly.

[0088] The top of the second box body 200 is provided with a first protrusion 11 and a second protrusion 12, which are respectively located at two opposite edges of the second box body 200. When the first box body 100 and the second box body 200 are locked, the bottom of the first box body 100 abuts against the first protrusion 11 and the second protrusion 12.

[0089] In some preferred embodiments, the locking member 3 and the first protrusion 11 are slidably matched through the second inclined surface 18, that is, at least one of the locking member 3 and the first protrusion 11 is provided with the second inclined surface 18. Here, the locking member 3 is provided with the second inclined surface 18, and the side of the first protrusion 11 close to the second protrusion 12 is provided as a straight surface perpendicular to the second direction. Specifically, a locking tongue is provided on the side of the end of the locking member 3 away from the operating member 2, so that the end of the locking member 3 forms a barb.

[0090] In the process of the first box body 100 and the second box body 200 approaching each other, the second inclined surface 18 on the locking member 3 contacts the straight surface on the first protrusion 11. Under the action of the second inclined surface 18, the locking member 3 displaces along the first direction and approaches the second box body 200, and the locking member 3 displaces along the second direction and moves away from the first protrusion 11. When the locking tongue on the locking member 3 is relative to the locking groove 10, under the action of the second elastic member 4, the locking tongue extends into the locking groove 10, that is, the locking member 3 in the above text extends into the locking groove 10, thereby limiting the separation of the first box body 100 and the second box body 200 along the first direction.

[0091] Thus, by setting the second inclined surface 18, when the first box body 100 and the second box body 200 are assembled, there is no need to manually operate the position of the locking member 3. The locking member 3 abuts against the first protrusion 11, so that the locking member 3 can automatically avoid and return to its position, which is convenient for assembling adjacent box bodies.

[0092] The embodiment of the present application provides a combined storage box, including a first box body 100, a second box body 200 and a locking assembly, wherein the first box body 100 and the second box body 200 are arranged adjacent to each other, such as the first box body 100 and the second box body 200 are arranged in a stacked manner, or the first box body 100 and the second box body 200 are arranged in abutment with each other left and right, and preferably, the first box body 100 is arranged on top of the second box body 200. The locking assembly is arranged as the locking assembly in the above embodiment.

[0093] With such a configuration, the locking structure is maintained in an unlocked state by the retaining structure, and the first box body 100 and the second box body 200 can be separated without applying a retaining force to the lock structure, which is conducive to the rapid disassembly of the assembled storage box, is simple to operate, and saves time and effort.

[0094] The top of the second box body 200 is provided with a first protrusion 11 and a second protrusion 12, and the first protrusion 11 and the second protrusion 12 are respectively located at two opposite edges of the second box body 200. The bottom of the first box body 100 is provided with a third protrusion 13 and a fourth protrusion 14, and the third protrusion 13 and the fourth protrusion 14 are respectively located at two opposite edges of the first box body 100. For example, the first box body 100 and the second box body 200 are square structures with the same volume, the first protrusion 11 and the second protrusion 12 are respectively located at two short sides, and the third protrusion 13 and the fourth protrusion 14 are respectively located at two long sides. When the first box body 100 and the second box body 200 are locked, the first protrusion 11 and the second protrusion 12 are both located between the third protrusion 13 and the fourth protrusion 14, and the third protrusion 13 and the fourth protrusion 14 are both located between the first protrusion 11 and the second protrusion 12, so that the first protrusion 11, the third protrusion 13, the second protrusion 12 and the fourth protrusion 14 are arranged in sequence and surrounded by a frame. In this way, by arranging the first protrusion 11, the second protrusion 12, the third protrusion 13 and the fourth protrusion 14, the first box body 100 and the second box body 200 can be prevented from being directly subjected to pressure, which is beneficial to protecting the items inside the box body and protecting the locking assembly.

[0095] In some preferred embodiments, the first box body 100 and the second box body 200 have the same volume, and the first box body 100 and the second box body 200 are both full-size boxes, or both are half-size boxes, and after the first box body 100 and the second box body 200 are stacked, the shapes are symmetrical, which is convenient for storage and transportation.

[0096] In some other preferred embodiments, the volume of the first box body 100 is smaller than the volume of the second box body 200. For example, the volume of the second box body 200 is twice the volume of the first box body 100, and of course it can also be three or four times, so that one of the first box body 100 and the second box body 200 is full size and the other is half size. Moreover, multiple first box bodies 100 can be locked with one second box body 200 at the same time through a locking assembly, thereby forming a stack of the first box body 100 and the second box body 200. In this way, stacking cooperation between boxes of multiple sizes can be achieved.

[0097] It can be understood that the above-mentioned description that the volume of the second box body 200 is twice the volume of the second box body 200 can be defined as: in the first direction (the arrangement direction of the first box body 100 and the second box body 200), the size of the second box body 200 is twice the size of the first box body 100; or, on the mating surface of the first box body 100 and the second box body 200, the side length of the second box body 200 is twice the side length of the first box body 100.

[0098] It should be noted that "parallel" in this application means that one direction is parallel to another direction, but it is not limited to the absolute parallelism of the two. For example, one is close to parallel to the other, and it is defined here that the angle between close to parallel is less than 2 degrees. "Vertical" in this article means that one direction is perpendicular to another direction, but it is not limited to the absolute perpendicularity of the two. For example, one is close to perpendicular to the other, and it is defined here that the angle between close to perpendicular is less than 92 degrees and greater than 88 degrees.
