[0049] The specific embodiments embodying the features and advantages of the present application will be described in the following description. It should be understood that the present application can be embodied in different embodiments and that each of the embodiments does not depart from the scope of the present application, and the description and drawings are essentially illustrative and not intended to limit the present application.

[0050] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indications of direction or positional relationship (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation. These descriptions are appropriate when the elements are in the positions shown in the drawings. If the positions of these elements change, the indications of these directions also change accordingly.

[0051] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0052] Please refer to Figure 1As shown, the present application provides a logistics turnover box 10, which comprises a top frame 100 and a bottom frame 200, and a side frame 300 and an end frame 400 arranged between the top frame 100 and the bottom frame 200. Among them, the end frame 400 can be two, and the two end frames 400 are arranged at the two ends of the bottom frame 200 in opposite directions. The side frame 300 can be two, and the two side frames 300 are arranged at the two sides of the bottom frame 200 in opposite directions. The bottom frame 200, the two side frames 300 and the two end frames 400 can be enclosed to form a box structure with a top opening, and the top frame 100 is arranged at the top opening of the box structure.

[0053] Among them, the top frame 100 comprises a cover plate 101 and a cover edge 102 extending circumferentially along the cover plate 101 and protruding downward from the lower surface of the cover plate 101. When the top frame 100 is arranged at the top opening of the box structure, the cover plate 101 abuts the upper end surface of the top opening of the box structure, and the cover edge 102 is arranged outside the circumferential side wall of the top opening of the box structure. That is to say, the top frame 100 can be buckled at the top opening of the box, and the circumferential edge of the top frame 100 protruding downward can prevent rainwater from entering the box.

[0054] For the sake of description, it is defined that the two ends of the logistics turnover box 10 where the two end frames 400 are located are the left and right directions, and the two sides of the logistics turnover box 10 where the two side frames 300 are located are the front and rear directions. It is defined that the side facing the inside of the box structure is the inside, and vice versa.

[0055] The logistics turnover box 10 of the present application has an assembled state and a folded state. Referring to Figure 1 As shown, the logistics turnover box 10 in the assembled state is in the shape of a rectangular parallelepiped. Referring to Figure 2 As shown, when the logistics turnover box 10 is in the folded state, the overall volume is reduced, which is beneficial to the storage and stacking of the logistics turnover box 10.

[0056] In detail, the bottom frame 200 comprises four corner columns 210, and each end frame 400 comprises two support columns 420, which are respectively located at the front and rear ends of the end frame 400. The bottom end of each support column 420 is rotatably connected to the corresponding corner column 210, so that the end frame 400 can be placed vertically relative to the bottom frame 200, or the end frame 400 can be folded on the bottom frame 200 by rotating inward.

[0057] Referring to Figure 1As shown, the corner post 210 comprises two side plates connected at an angle, which are respectively fixedly attached to the two outer sides of the bottom frame 200. One side plate is used for hinging with the support post 420, and the other side plate is used for abutting against the support post 420 to prevent the end frame 400 from rotating outward. A long hole 212 is formed in the side plate hinged with the support post 420, and the bottom end of the support post 420 is provided with a connecting hole corresponding to the long hole 212. The bottom end of the support post 420 is connected to the corner post 210 in rotation by means of a fastener penetrating through the long hole 212 and the connecting hole.

[0058] Further, a limiting block 421 is arranged on the side surface of the support post 420, and a limiting hole is arranged on the side plate hinged with the support post 420. The limiting block 421 extends vertically and serves to limit the vertical displacement of the end frame 400. The lower end of the limiting block 421 is detachably embedded in the limiting hole at the top of the corner post 210. The limiting block 421 serves to cooperate with the corner post 210 when the end frame 400 is vertical, thereby limiting the relative displacement of the end frame 400 in the horizontal direction and ensuring that the end frame 400 is in a stable vertical assembled state.

[0059] When folding is needed, the end frame 400 is pulled upward to make the limiting block 421 disengage from the limiting hole, so that the support post 420 rotates inward, and thus the end frame 400 can be folded inward on the bottom frame 200, realizing the folding and storage of the logistics turnover box 10 and improving the use convenience of the logistics turnover box 10.

[0060] Referring to Figure 1 As shown, the lower end of each corner post 210 is provided with a buckle cup 211, and the lower end of the buckle cup 211 is internally hollow to form a receiving groove. The top frame 100 comprises a top cap 110 protruding upward from the top frame 100, and the top cap 110 is arranged in correspondence with the buckle cup 211 in the vertical direction and can be inserted into the receiving groove. By arranging the buckle cup 211 and the corresponding top cap 110, the plurality of logistics turnover boxes 10 can be stacked, the floor area can be reduced, and the storage and storage can be facilitated.

[0061] Preferably, the buckle cup 211 is gradually expanded from top to bottom. The cross section of the buckle cup 211 is rectangular. The lower end of the buckle cup 211 has the largest diameter, so that the top cap 110 can be more easily aligned and inserted into the receiving groove inside the buckle cup 211 when stacked. The upper end of the top cap 110 has the same size as the smallest cross section of the buckle cup 211, i.e., the upper end of the top cap 110 can be inserted into the innermost part of the buckle cup 211 upward, preventing the top cap 110 from disengaging from the buckle cup 211.

[0062] In combination with Figure 2 and Figure 3As shown, in use, when the plurality of logistics turnover boxes 10 are stacked up and down, the top caps 110 of the lower logistics turnover boxes 10 correspondingly extend into the accommodation grooves of the buckle cups 211 directly above, achieving vertical stacking positioning.

[0063] Further, the lower end of the top cap 110 is internally hollow, so that the upper end of the corner column 210 can be fitted into the internal cavity of the lower end of the top cap 110. Thus, the top frame 100 and the bottom frame 200 of the logistics turnover box 10 in the folded state are reliably positioned and connected vertically.

[0064] The plurality of logistics turnover boxes 10 are stacked according to the above stacking method. As the weight increases, the top cap 110 and the buckle cup 211 or the corner column 210 of the adjacent upper and lower logistics turnover boxes 10 are embedded more tightly, and a firm and stable connection relationship can be achieved without other auxiliary fixing devices.

[0065] The logistics turnover box 10 of the present application is in an assembled state, and the two end frames 400 are vertically placed relative to the bottom frame 200, and the side frames 300 are assembled relative to the two end frames 400. The end frame 400 can support the side frame 300 to be vertically placed relative to the bottom frame 200. Details are shown in Figure 4 As shown, the two end frames 400 are vertically arranged at the left and right ends of the bottom frame 200, and the left end of each side frame 300 is assembled and connected with one end frame 400, and the right end is assembled and connected with the other end frame 400.

[0066] In combination Figure 5 As shown, the top end of the end frame 400 is provided with a fixing part 410, and the fixing part 410 has a positioning groove 411 opening upward. The top end of the side frame 300 is provided with a connecting part 310 corresponding to the fixing part 410, and the connecting part 310 can be inserted into the positioning groove 411 to position and connect the side frame 300 with the end frame 400. By providing the fixing part 410 at the top end of the end frame 400, and the fixing part 410 has a positioning groove 411 opening upward, and the connecting part 310 is provided at the top end of the side frame 300, and the connecting part 310 can be inserted into the positioning groove 411 to position and connect the side frame 300 with the end frame 400, so that the two side frames 300 can be quickly assembled between the two end frames 400. When the logistics turnover box 10 needs to be folded, the side frame 300 can be quickly removed from the end frame 400, thereby facilitating the use of the logistics turnover box 10.

[0067] In the present application, the fixing portion 410 is not protrudingly arranged on the surface of the box structure. The connecting portion 310 is also not protrudingly arranged on the surface of the box structure. That is to say, after the side frame 300 and the end frame 400 are assembled and form the box structure with the bottom frame 200, the fixing portion 410 and the connecting portion 310 cannot be seen from the outside of the surface of the box structure. The fixing portion 410 and the connecting portion 310 of the present application are not externally arranged, and the problem of easy collision and damage caused by the externally arranged connecting structure of the existing packaging box can be solved.

[0068] Preferably, the fixing portion 410 is a fixing plate protrudingly arranged from the surface of the self-supporting column 420 to the side frame 300. As shown in Figure 6 and Figure 7 , the fixing plate is protrudingly arranged from the surface of the self-supporting column 420 to the right side frame 300. By designing the fixing portion 410 as a fixing plate protrudingly arranged from the surface of the self-supporting column 420 to the side frame 300, the fixing portion 410 does not protrude from the front and rear ends of the end frame 400, thereby facilitating the structure of the connection between the side frame 300 and the end frame 400 not to be exposed to the surface of the box when they are assembled.

[0069] As shown in Figure 8 , the fixing plate extends along the height direction of the supporting column 420, and the positioning groove 411 is arranged at the top end of the fixing plate. The fixing plate extending along the height direction of the supporting column 420 is beneficial to strengthening the structural strength of the fixing portion 410 and facilitating the connection and support of the side frame 300.

[0070] Further, the fixing plate comprises a first plate body 413 and a second plate body 414 connected with each other, the side of the first plate body 413 away from the second plate body 414 is connected with the supporting column 420, and the second plate body 414 is arranged in parallel and spaced apart from the supporting column 420, and the positioning groove 411 is arranged at the top end of the second plate body 414. In the present example, the first plate body 413 and the second plate body 414 form a fixing plate with a cross-sectional shape substantially in the shape of L, and the first plate body 413 and the second plate body 414 can form a receiving cavity 412 with an opening.

[0071] As shown in Figure 7 and Figure 9As shown, the side frame 300 comprises a connecting column 320. The connecting column 320 can have a U-shaped cross section, and has a first side wall 321 and a second side wall 322 which are parallel to the support column 420, and a third side wall 323 connecting the first side wall 321 and the second side wall 322. When the side frame 300 is assembled with the end frame 400, the first side wall 321 of the connecting column 320 can be inserted into the receiving cavity 412 from the opening of the receiving cavity 412, that is, the connecting column 320 can be connected with the fixing plate by mutual buckling, so that the side frame 300 can be installed between the two end frames 400 in the left-right direction. At the same time, the first side wall 321 of the left and right ends of the side frame 300 can only be slightly displaced within the width range of the receiving cavity 412 in the left-right direction, so that there is only a small assembly gap between the side frame 300 and the end frame 400, facilitating the assembly of the side frame 300 with the end frame 400, or facilitating the disassembly of the side frame 300 from the end frame 400.

[0072] As shown in Figure 7 and Figure 9 As shown, the connecting part 310 is a connecting plate arranged at the top end of the connecting column 320. The two ends of the connecting plate are connected to the first side wall 321 and the second side wall 322, respectively. In the present example, the connecting plate is integrated inside the main frame (i.e. the connecting column 320) of the side frame 300, and the connecting plate is not exposed outside the side frame 300, so that when the side frame 300 is positioned and connected with the end frame 400 through the connecting plate, the connecting and fitting position of the connecting plate and the positioning groove 411 is completely hidden in the connecting column 320. Therefore, the connection between the side frame 300 and the end frame 400 of the present application can be completely exposed, that is, no part of the connecting and fitting structure of the side frame 300 and the end frame 400 is exposed outside the box. Thus, damage to the connecting parts due to collision during transportation or use of the logistics turnover box 10 can be effectively avoided.

[0073] As shown in Figure 5 As shown, part of the connecting plate can be inserted downward into the positioning groove 411. In one example, the connecting plate has a substantially L-shaped cross section, and one side plate body of the connecting plate extends downward. Thus, the side plate body of the connecting plate can be inserted downward into the positioning groove 411, achieving the positioning and connection of the side frame 300 and the end frame 400. The positioning groove 411 can be a U-shaped groove, and the groove width can be slightly larger than the thickness of the plate body of the connecting plate, so as to facilitate the insertion of the connecting plate into the positioning groove 411 and form a reliable connection.

[0074] In other embodiments, the fixed part 410 can be a fixed frame protruding from the surface of the support column 420 towards the side frame 300, and a positioning groove 411 is formed between the fixed frame and the support column 420. The connecting part 310 can be a connecting hook protruding from the surface of the connecting column 320 towards the end frame 400, and the connecting hook has a hook portion extending downward. The side frame 300 and the end frame 400 are positioned and connected by inserting the hook portion of the connecting hook downward into the positioning groove 411.

[0075] In the present application, when the side frame 300 and the end frame 400 are assembled, the L-shaped fixed plate on the end frame 400 and the U-shaped column of the side frame 300 are connected to limit the left and right movement of the side frame 300, and the left and right ends of the side frame 300 are respectively limited in the accommodation cavity 412. At the same time, the L-shaped connecting plate on the U-shaped column of the side frame 300 is inserted and matched with the positioning groove 411 on the L-shaped fixed plate of the end frame 400 to limit the front and back movement of the side frame 300, thereby realizing the reliable connection and assembly of the side frame 300 and the end frame 400, and facilitating the disassembly of the side frame 300. The connection between the side frame 300 and the end frame 400 can be completely exposed, thereby effectively avoiding damage to the connecting parts of the logistics turnover box 10 during transportation or use due to collision.

[0076] Continuing to refer to Figure 5 As shown, the end frame 400 is formed with a first vertical surface 430, which can be a vertical wall surface formed by connecting the fixed plate and the support column 420.

[0077] The side frame 300 is formed with a second vertical surface 330, which can be a vertical wall surface formed by the U-shaped connecting column 320.

[0078] After the side frame 300 and the end frame 400 are connected and assembled, the first vertical surface 430 and the second vertical surface 330 are inserted into each other and have a gap therebetween to form a water guide channel. Therefore, when the logistics turnover box 10 is used, if it encounters rainy weather, since the first vertical surface 430 and the second vertical surface 330 form a water guide channel therebetween, rainwater and the like can flow downward along the water guide channel and cannot enter the box. In other words, the first vertical surface 430 and the second vertical surface 330 can cooperate to form a labyrinth waterproof effect.

[0079] In other embodiments, the first vertical surface 430 can also be a vertical wall surface protruding from the support column 420 towards one side of the side frame 300, and the cross section of the vertical wall surface is in the shape of a "convex" character. The second vertical surface 330 is a vertical wall surface in the shape of a "concave" character, and the second vertical surface 330 is arranged in a concave-convex opposite interval with the first vertical surface 430, so that the two can also cooperate to form a labyrinth waterproof effect.

[0080] Please refer back to Figure 1The bottom frame 200 comprises two side beams 220 corresponding to the two side frames 300 and two end beams 230 corresponding to the two end frames 400, and the two side beams 220 and the two end beams 230 are sequentially connected in a head-to-tail manner to form a rectangular frame body.

[0081] Preferably, a drainage gap can be arranged between each side frame 300 and the corresponding side beam 220. That is, when the end frame 400 supports the side frame 300 to be placed vertically relative to the bottom frame 200 after the side frame 300 is connected and assembled with the end frame 400, a certain gap exists between the side frame 300 and the side beam 220 of the bottom, which can be used for drainage at the bottom of the side frame 300. Thus, the drainage gap can prevent water storage.

[0082] Further, a pad 340 can be arranged at the bottom of the side frame 300, which can abut against the side beam 220 to support the side frame 300, so that the above-mentioned drainage gap can be formed between the side frame 300 and the side beam 220.

[0083] Preferably, a drainage gap can also be arranged between each end frame 400 and the corresponding end beam 230. That is, when the end frame 400 is placed vertically by connecting the bottom end of the support column 420 of the end frame 400 with the corresponding corner column 210, a certain gap exists between the bottom end of the end frame 400 and the end beam 230, which can be used for drainage at the bottom of the end frame 400.

[0084] A plurality of reinforcing beams are connected between the two side beams 220 and the two end beams 230, respectively, to respectively reinforce the connection strength between the two side beams 220 and the two end beams 230, and to simultaneously reinforce the bearing strength of the bottom frame 200.

[0085] As shown in Figure 4 The bottom frame 200 further comprises a tray 240 connected between the two side beams 220 and the two end beams 230 and located above the reinforcing beams. At this time, the plurality of reinforcing beams between the two side beams 220 and the two end beams 230 can support the tray 240. The tray 240 can further be provided with longitudinally and transversely arranged support frames 241 for supporting goods.

[0086] The circumferential edge of the tray 240 is upwardly protruding, which is used to resist the penetration of water from the bottom of the end frame 400 and the side frame 300 into the inside of the box. The circumferential upwardly protruding edge of the tray 240 can have a gap between the two side beams 220 and the two end beams 230, which is used for drainage at the bottom of the end frame 400 and the side frame 300.

[0087] Referring to Figure 1 and Figure 2The bottom of the bottom frame 200 comprises four first and last connected bottom beams 250. Two ends of each bottom beam 250 can be connected between two buckle cups 211 at lower ends of two adjacent corner columns 210. Among the four bottom beams 250, two bottom beams 250 are longer and extend along the left-right direction, and are arranged below the two side beams 220 one by one. The remaining two bottom beams 250 are shorter and extend along the front-back direction, and are arranged below the two end beams 230 one by one. A plurality of support columns 251 are separately connected between each long bottom beam 250 and each side beam 220, and between each short bottom beam 250 and each end beam 230. Among them, the interval between two adjacent support columns 251 can form a fork groove for the fork of the forklift to extend into, so that the transportation of the logistics turnover box 10 can be realized.

[0088] The bottom frame 200 also forms a limiting structure 500 limiting the bottom end of the side frame 300. By setting the limiting structure 500, the bottom end of the vertically placed side frame 300 can be limited, so as to limit the relative displacement of the bottom end of the side frame 300 along the front-back direction, and ensure that the side frame 300 is in a stable vertical assembly state.

[0089] In an embodiment, the limiting structure 500 comprises a first limiting part 510 and a second limiting part 520, and the first limiting part 510 and the second limiting part 520 are arranged on both sides of the side beam 220. The first limiting part 510 and the second limiting part 520 can respectively abut against the front and back sides of the bottom end of the side frame 300.

[0090] Referring to Figure 1 and Figure 2 The first limiting part 510 can be a U-shaped handle arranged on the outer side of the side beam 220 in the front-back direction. The two ends of the U-shaped handle are fixedly connected to the side beam 220, and the upper end of the U-shaped handle serves as a limiting part. The number of U-shaped handles can be one, two or more. Two or more U-shaped handles are arranged along the length direction of the side beam 220.

[0091] In addition, when the logistics turnover box 10 is in a folded state, the U-shaped handle can also cooperate with the through hole 121 on the limiting plate 120 to lock the top frame 100 and the bottom frame 200. For example, the fixed binding belt can be passed through the U-shaped handle and the corresponding through hole 121 to realize the binding of the top frame 100 and the bottom frame 200 to prevent shaking.

[0092] In other embodiments, the first limiting part 510 can also be a limiting protruding plate arranged on the outer side of the side beam 220 in the front-back direction. The number of limiting protruding plates can be one, two or more. Two or more limiting protruding plates are arranged along the length direction of the side beam 220.

[0093] The second limiting part 520 can be formed by the circumferential upward protruding edge of the tray 240. That is, the edge of the tray 240 extending along the length direction of the side beam 220 forms the second limiting part 520 capable of playing a limiting role. Thus, the second limiting part 520 playing a limiting effect is formed by the structure of the tray 240 itself, so that the box structure is simpler, and no additional limiting parts are needed, thereby simplifying the manufacturing process and saving the manufacturing cost.

[0094] In other embodiments, the second limiting part 520 can also be a limiting beam arranged on the inner side of the side beam 220 in the front-rear direction, and the limiting beam can extend along the length direction of the side beam 220. The limiting beam can be in full contact with the inner side of the bottom end of the side frame 300 to ensure good limiting effect on the bottom end of the side frame 300.

[0095] Further, the first limiting part 510 is formed with a guide slope facing the side of the second limiting part 520, and the guide slope can guide the bottom end of the side frame 300 to move to the side of the second limiting part 520 until abutting against the side beam 220. Figure 1 As shown, the upper end of the U-shaped handle is arranged obliquely, thereby forming a guide slope that shrinks inward from top to bottom. When the side frame 300 is assembled with the end frame 400, the bottom end of the side frame 300 can shrink inward along the guide slope and smoothly enter the limiting space between the first limiting part 510 and the second limiting part 520 until abutting against the side beam 220.

[0096] It can be understood that when the logistics turnover box 10 is in a folded state, the two end frames 400 are folded inward on the bottom frame 200. That is, the support column 420 of the end frame 400 can be folded down and coincide above the side beam 220. At this time, the first limiting part 510 and / or the second limiting part 520 can also limit the support column 420 in the folded-down state to avoid the front-rear shaking of the end frame 400.

[0097] In other embodiments, the first limiting part 510 can also be a limiting block arranged on one side of the side beam 220, and the second limiting part 520 can be a limiting block arranged on the opposite side of the side beam 220. The front-rear sides of the bottom end of the side frame 300 can respectively abut against the limiting blocks on the two sides of the side beam 220, thereby limiting the bottom end of the side frame 300.

[0098] When the logistics turnover box 10 of the present application needs to be folded and stored, the two side frames 300 are first pulled up to be detached from the two end frames 400, and then the two end frames 400 are pulled up to make the limiting blocks 421 disengage from the limiting holes, so that the two end frames 400 can be folded inward on the bottom frame 200. Finally, the top frame 100 is buckled above the corner columns 210 of the bottom frame 200.

[0099] In an embodiment, the logistics turnover box 10 further comprises a plurality of limiting plates 120, which are arranged along the circumference of the top frame 100 and protrude downward from the top frame 100. Referring to Figure 2 The plurality of limiting plates 120 can limit the movement of the disassembled side frame 300, thereby protecting the components of the logistics turnover box 10. Further, each limiting plate 120 is provided with a through hole 121. The through hole 121 is used to pass through the external fixing strap.

[0100] For example, as shown in Figure 2 When the logistics turnover box 10 is in the folded state, the position of the limiting plate 120 is opposite to the position of the first limiting part 510. For example, when the first limiting part 510 is a U-shaped handle, the locking of the top frame 100 and the bottom frame 200 can be achieved by passing the fixing strap through the through hole 121 of the limiting plate 120 and the U-shaped handle.

[0101] As shown in Figure 1 The upper end of the end frame 400 and the upper end of the side frame 300 are provided with a handle 11 corresponding to each limiting plate 120. When the logistics turnover box 10 is in the assembled state, after the top frame 100 is covered on the top opening of the box structure, the locking of the top frame 100 and the bottom frame 200 can be achieved by passing the fixing strap through the through hole 121 of the limiting plate 120 and each handle 11. The handle 11 provided on the end frame 400 and the side frame 300 also serves to facilitate lifting the end frame 400 and the side frame 300.

[0102] In addition, the lower end of the side frame 300 can also be provided with a handle 11 corresponding to each first limiting part 510. When the logistics turnover box 10 is in the assembled state, the locking of the side frame 300 and the bottom frame 200 can be achieved by passing the fixing strap through the handle 11 at the lower end of the side frame 300 and the first limiting part 510 (U-shaped handle).

[0103] Further, the top of the top frame 100 is further provided with a plurality of handles 130, which facilitate the user to lift the top frame 100.

[0104] The main support structure of the logistics turnover box 10 in each embodiment of the present application can be made of a metal material with high strength, such as steel. For example, the top frame 100, the end beam 230, the side beam 220, the corner column 210, and the tray 240 of the bottom frame 200, the connecting column 320 of the side frame 300, and the support column 420 and the fixing plate of the end frame 400 are made of steel. The plate body part of the side frame 300 and the plate body part of the end frame 400, the handle 11, and the handle 130, etc. can be made of a material with slightly lower strength, such as aluminum or aluminum alloy, which is not limited in the present application.

[0105] The above embodiments are only illustrative of the structure, and the structures in the embodiments are not fixedly combined. In the absence of structural conflicts, the structures in the embodiments can be combined arbitrarily.
