In the logistics turnover box 10 of the present application, the two end frames 400 are vertically arranged with respect to the bottom frame 200 in the assembled state, the two side frames 300 are assembled between the two end frames 400 at a relatively spaced distance, and the end frames 400 can support the side frames 300 to be vertically arranged with respect to the bottom frame 200. As shown in fig. 4, two end frames 400 are respectively vertically disposed at the left and right ends of the bottom frame 200, the left end of each side frame 300 is assembled with one end frame 400, and the right end is assembled with the other end frame 400.

As shown in fig. 5, the top end of the end frame 400 is provided with a fixing portion 410, and the fixing portion 410 has a positioning slot 411 opened 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 downwards into the positioning slot 411 to position and connect the side frame 300 with the end frame 400. By providing the fixing portion 410 at the top end of the end frame 400, the fixing portion 410 has the positioning slot 411 opened upward, and the connecting portion 310 is provided at the top end of the side frame 300, and the connecting portion 310 can be inserted into the positioning slot 411 to enable the side frame 300 to be positioned and connected with the end frame 400, so that the side frames 300 can be assembled between the two end frames 400 quickly. And when it is desired to fold the logistics turnover box 10, the side frames 300 can be rapidly detached from the end frames 400, thereby facilitating the use of the logistics turnover box 10.

In the present application, the fixing portion 410 is not protruded from the surface of the case structure. The connection portion 310 is not provided protruding from the surface of the case structure. That is, after the side frames 300 and the end frames 400 are assembled and the case structure is formed with the bottom frame 120, the fixing portion 410 and the connection portion 310 are not visible from the outside of the surface of the case structure. The fixing part 410 and the connecting part 310 are not externally arranged, so that the problem that the existing packing box is easy to collide and damage due to external connecting structure can be solved.

Preferably, the fixing portion 410 is a fixing plate protruding from the surface of the supporting pillar 420 toward the side frame 300. As shown in fig. 6 and 7, the fixing plate protrudes from the surface of the supporting pillar 420 toward the right side frame 300. By designing the fixing portion 410 as a fixing plate protruding from the surface of the supporting upright 420 toward the side frame 300, the fixing portion 410 does not protrude from the front and rear end sides of the end frame 400, so that the structure at the joint between the side frame 300 and the end frame 400 is not exposed from the surface of the case when the two are assembled.

Referring to fig. 8, the fixing plate extends along the height direction of the support post 420, and the positioning slot 411 is formed at the top end of the fixing plate. The fixing plate extends along the height direction of the support column 420, which is advantageous in reinforcing the structural strength of the fixing portion 410, and facilitating connection and support of the side frame 300.

Further, the fixing plate comprises a first plate 413 and a second plate 414, the first plate 413 is connected with the support column 420 at a side far away from the second plate 414, the second plate 414 is arranged at intervals parallel to the support column 420, and the positioning slot 411 is formed in the top end of the second plate 414. In this example, the first plate 413 and the second plate 414 form a fixing plate with a substantially L-shaped cross section, and the first plate 413 and the second plate 414 can enclose to form a housing chamber 412 with an opening.

Referring to fig. 7 and 9, the side frame 300 includes a connection post 320. The connection post 320 may have a U-shaped cross-section, and the connection post 320 has a first sidewall 321 and a second sidewall 322 parallel to and opposite to the support post 420, and a third sidewall 323 connecting the first sidewall 321 and the second sidewall 322. When the side frames 300 and the end frames 400 are assembled, the first side walls 321 of the connecting columns 320 can be inserted into the accommodating cavities 412 from the openings of the accommodating cavities 412, that is, the connecting columns 320 can be fastened and connected with the fixing plates, so that the side frames 300 can be mounted between the two end frames 400 in a limiting manner in the left-right direction. Meanwhile, the first side walls 321 at the left and right ends of the side frame 300 can only make a small displacement within the width range of the accommodating cavity 412 along the left and right direction, so that only a small assembly gap exists between the side frame 300 and the end frame 400, which is convenient for the smooth assembly of the side frame 300 and the end frame 400, or the smooth disassembly of the side frame 300 from the end frame 400.

Referring to fig. 7 and 9, the connection portion 310 is a connection plate provided at the top end of the connection post 320. The two ends of the connecting plate are respectively connected to the first side wall 321 and the second side wall 322. In this example, the connection plate is integrated inside the main body frame (i.e. the connection upright 320) of the side frame 300, and the connection plate is not exposed out of the side frame 300, so that when the side frame 300 is positioned and connected with the end frame 400 through the connection plate, the connection matching part of the connection plate and the positioning slot 411 is completely hidden in the connection upright 320. Therefore, the connection between the side frame 300 and the end frame 400 of the present application can not be exposed at all, that is, the connection and matching structure between the side frame 300 and the end frame 400 is not exposed outside the case. Thereby effectively avoiding the damage to the connecting parts of the logistics turnover box 10 due to collision during transportation or use.

Referring to fig. 5, a portion of the connection plate can be downwardly inserted into the positioning slot 411. In one example, the connecting plate has a structure with a substantially L-shaped section, and a side plate body of the connecting plate extends downwards. So that the side plate body of the connection plate can be downwardly inserted into the positioning slot 411 to realize the positioning connection of the side frame 300 and the end frame 400. The positioning slot 411 may be a U-shaped slot, and the slot width of the U-shaped slot may be slightly larger than the thickness of the plate body of the connecting plate, so that the connecting plate is inserted into the positioning slot 411 downward and forms a reliable connection.

In other embodiments, the fixing portion 410 may be a fixing frame protruding from the surface of the supporting pillar 420 toward the side frame 300, and an upwardly open positioning slot 411 is formed between the fixing frame and the supporting pillar 420. The connection portion 310 may be a connection hook having a hook portion extending downward, which is provided to protrude from the surface of the connection post 320 toward the end frame 400. The side frames 300 and the end frames 400 are positioned and connected by inserting the hook portions of the connecting hooks downward into the positioning slots 411.

In the present application, when the side frame 300 is assembled with the end frame 400, the side frame 300 is limited to move left and right by connecting the L-shaped fixing plate on the end frame 400 with the U-shaped column of the side frame 300, and the left and right ends of the side frame 300 are respectively limited in the receiving chamber 412. Meanwhile, the L-shaped connecting plate on the U-shaped upright post of the side frame 300 is in plug-in fit with the positioning slot 411 on the L-shaped fixing plate of the end frame 400, so that the side frame 300 is limited to move back and forth, reliable connection assembly of the side frame 300 and the end frame 400 is realized, and meanwhile, the side frame 300 is easy to disassemble. And the connection part of the side frames 300 and the end frames 400 can not be exposed at all, so that the damage of connection parts of the logistics turnover box 10 due to collision in the transportation or use process can be effectively avoided.

With continued reference to fig. 5, the end frame 400 is formed with a first elevation 430. The first elevation 430 may be an upstanding wall formed by the attachment of the above-described securing plate to the support post 420.

The side frame 300 is formed with a second elevation 330, and the second elevation 330 may be an upright wall surface formed by the U-shaped connecting upright 320.

After the side frames 300 and the end frames 400 are assembled, the first vertical surfaces 430 and the second vertical surfaces 330 are inserted into each other with a space therebetween to form a water guiding channel. Thus, in use, in the event of rain, the first and second vertical surfaces 430, 330 form a water guide path therebetween, so that rain water or the like can flow downwardly along the water guide path without entering the box. In other words, the first and second facades 430, 330 are capable of cooperating to form a labyrinth waterproof effect.

In other embodiments, the first elevation 430 may be an upright wall surface protruding from the supporting upright 420 toward the side frame 300, and having a "convex" cross section. The second vertical surface 330 is a concave vertical wall surface correspondingly, and the second vertical surface 330 and the first vertical surface 430 are arranged at intervals in a concave-convex manner, so that the two surfaces can also cooperate to form a labyrinth waterproof effect.

Referring back to fig. 1, the bottom frame 200 includes 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 end to form a rectangular frame body.

Preferably, a drainage gap may be provided between each side frame 300 and the corresponding side member 220. That is, when the end frame 400 supports the side frame 300 to be erected with respect to the bottom frame 200 after the side frame 300 is coupled to the end frame 400, a certain gap exists between the side frame 300 and the bottom side member 220, and the gap can be used for drainage of the bottom of the side frame 300. Thereby can play the effect that prevents the water storage through setting up the drainage clearance.

Further, the bottom of the side frame 300 may be provided with a spacer 340, and the spacer 340 may be abutted against the side frame 220 to support the side frame 300, so that the drainage gap may be formed between the side frame 300 and the side frame 220.

Preferably, a drainage gap is also provided between each end frame 400 and the corresponding end beam 230. That is, when the end frame 400 is vertically placed by connecting and matching the bottom ends of the supporting columns 420 of the end frame 400 with the corresponding corner columns 210, a certain gap exists between the bottom ends of the end frame 400 and the end beams 230 for draining the bottom of the end frame 400.

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

Referring to fig. 4, the bottom frame 200 further includes a tray 240, and the tray 240 is connected between the two side beams 220 and the two end beams 230 and above the reinforcement beams. At this time, the plurality of reinforcing beams between the both side beams 220 and the both side beams 230 can support the tray 240. The tray 240 may further be provided with supporting frames 241 disposed in a crisscross arrangement for supporting goods.

There may be a gap between the rim of the tray 240 protruding upward in the circumferential direction and the both side beams 220 and 230 for draining the bottoms of the end frames 400 and 300.

Referring to fig. 1 and 2, the bottom of the bottom frame 200 includes four bottom beams 250 that are connected end to end. Both ends of each bottom beam 250 may be respectively connected between two fastening cups 211 at the lower ends of the adjacent two corner posts 210. Of the four bottom beams 250, two bottom beams 250 have a longer length and extend in the left-right direction, and are disposed below the two side beams 220 in a one-to-one correspondence. The remaining two bottom beams 250 are shorter in length and extend in the front-rear direction, and are disposed under the two end beams 230 in a one-to-one correspondence. A plurality of support columns 251 are connected between each long bottom beam 250 and each side beam 220, and between each short bottom beam 250 and each end beam 230 at intervals. Wherein, the interval between two adjacent support columns 251 can form a fork groove for the fork of the forklift to extend into, thereby realizing the transportation of the logistics turnover box 10.
