DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] See also Figure 1-6 The utility model provides a technical solution: a foldable turnover box, including a chassis 1, two side panels 2, two end panels 3, an upper cover 4 and a latch plate 5. The four sides of the top of the chassis 1 are provided with grooves, each of which is fixedly connected to a support shaft 11. The bottoms of the side panels 2 and the end panels 3 are respectively fixedly connected to a clamping sleeve 6 that is embedded in the support shaft 11, and the side panels 2 and the end panels 3 are respectively flipped around the support shaft 11.

[0027] The sleeve 6 is a cylindrical structure with a semi-open outer side, and is sleeved onto the support shaft 11 from the inner side, so that the side plate 2 and the end plate 3 can be flipped freely and independently, and can be flipped inward into the chassis 1, or flipped outward so that the top end falls on the ground.

[0028] Since the clamping sleeve 6 is clamped onto the support shaft 11 from the inside and the open side is on the outside, when the side panels 2 and the end panels 3 are rotated to a vertical state to form a box body, the clamping sleeve 6 will only clamp the support shaft 11 and will not be separated from the support shaft 11 when squeezed by the internal cargo.

[0029] The support shafts 11 on both sides of the chassis 1 are in different horizontal planes from the support shafts 11 at both ends. When the side panels 2 and the end panels 3 are rotated to a vertical state, their tops are in the same horizontal plane to form a box-type structure with an open top. Both sides of the end panels 3 are provided with connecting parts 31 extending from the ends of the side panels 2, and the connecting parts are fastened to the ends of the outer sides of the side panels 2.

[0030] The height of the bottom ends of the two side panels 2 is lower than the height of the bottom ends of the two end panels 3, so that a height difference is formed, and the height of the side panels 2 is less than or equal to the width of the inner cavity of the chassis 1, and the sum of the heights of the two end panels 3 is less than or equal to the length of the inner cavity of the chassis 1. When not in use, the two side panels 2 can be flipped inward and staggered up and down into the chassis 1, and then the two end panels 3 can be flipped inward to be horizontal. The two together cover the top of the chassis 1, and the two sides are pressed on the two side edges of the chassis 1 respectively, so that the entire box body is folded to form a flat structure, which reduces the size of the occupied space and is convenient for stacking, storage and transportation.

[0031] There may also be a slight height difference between the bottom ends of the side panels 2 on both sides, so that both side panels 2 can be rotated to a horizontal position when flipped inward, with one side panel 2 pressed on the other side panel 2, and then the two end panels 3 pressed on the upper side panel 2, so that the top of the folded box is relatively flat and easy to stack.

[0032] The bottom ends of the two side panels 2 can also be at the same height, and both are tilted and retracted into the chassis 1, and the end panels 3 are supported by the outer sides of the tops of the two side panels 3 (referring to the bottom of the outer sides in the folded state, i.e., the erected state).

[0033] The thickness of the two ends of the side panel 2 is thinned to form a step shape so as to match with the connecting portion 31. A plurality of connecting grooves are arranged at intervals at the thinned positions at the two ends of the side panel 2, and a connecting block corresponding to the connecting groove is arranged on the inner side of the connecting portion 31. The connecting block and the connecting groove are both in the shape of a triangle, a trapezoid or a dovetail, so that the connecting block cannot be directly pulled out of the connecting groove in a translation state, and can only be separated by rotating so that the two are in different planes. When assembled, the connecting block is inserted into the connecting groove, so that the connecting portion 31 is tightly buckled at the end of the side panel 2, so that the side panel 2 and the end panel 3 are tightly connected, and at the same time, the outer side of the connecting portion 31 is flush with the surface of the side panel 2, and the outer surface of the entire box body is relatively flat.

[0034] When in use, the two end panels 3 can be rotated to a vertical state first, and then the two side panels 2 can be flipped up from the inside to a vertical state. During this process, the connecting block will gradually be stuck in the connecting groove, so that the end panel 3 is tightly connected to the side panel 2 through the connecting portion 31. The two support each other, so that they cannot be rotated inward or outward without external force, so that the two side panels 2 and the two end panels 3 form a relatively stable box-type structure, which is convenient for loading goods into the box.

[0035] The end plate 2 is provided with a buckle handle for easy transportation.

[0036] The upper cover 4 is detachably arranged at the opening of the box-shaped structure.

[0037] In this embodiment, after the upper cover 4 is installed in place, the side panels 2 and the end panels 3 can be fixed so that the entire box body remains stable.

[0038] Furthermore, a card slot 21 is provided on the upper edge of the outer side of the side panel 2, and buckles 41 that can be snapped into the card slot 21 are provided on both sides of the bottom of the upper cover 4, and a first limiting strip 42 that can be tightly attached to the inner side of the side panel 2 is provided on both sides of the bottom of the upper cover 4 and on the inner side of the buckle 41.

[0039] like Figure 2 , 6 -9, grooves 43 are provided at both ends of the bottom of the upper cover 4, a protrusion 32 which can be snapped into the groove 43 is provided on the top of the end plate 3, and a second limiting strip 44 which can be tightly attached to the inner side of the end plate 3 is provided on both sides of the bottom of the upper cover 4 and located on the inner side of the groove 43.

[0040] In this embodiment, when the side panel 2 and the end panel 3 are rotated to a vertical state and spliced ​​together to form a box body, after the goods are loaded into the box body, the upper cover 4 is closed from the top, the top of the side panel 2 is clamped between the buckle 41 and the first limit strip 42, the buckle 41 is buckled into the groove 21 on the surface of the side panel 2 for positioning, the top of the end panel 3 is clamped on the outside of the second limit strip 44, and the protrusion 32 on the top of the end panel 3 is clamped into the groove 43, so that the upper cover 4 fixes the side panel 2 and the end panel 3.

[0041] Furthermore, a receiving groove 45 is provided at the top of the upper cover 4 and extends downwardly to the middle of the side edge. A limiting buckle 46 is fixedly connected to the upper part of the inner cavity of the receiving groove 45. A locking hole 22 connected to the outer end of the receiving groove 45 is provided at the top of the inner side surface of the side panel 2. The end of the locking pin plate 7 passes through the receiving groove 45 from under the limiting buckle 46 and is inserted into the locking hole 22.

[0042] The receiving groove 45 extends to the side of the upper cover 4 and forms a slot hole on the side. The receiving groove 45 does not penetrate to the top at the edge of the upper cover 4, and the bayonet plate 5 is fixed through the slot hole.

[0043] Furthermore, a through hole is formed on the limit buckle 46 , and a pressable elastic block 51 is provided on the latch plate 5 , and the elastic block 51 can be inserted into the through hole.

[0044] In this embodiment, after the upper cover 4 is installed in place, the bayonet plate 5 is inserted from the inner end of the receiving groove 45, and the end of the bayonet plate 5 passes through the slot hole from the inner cavity of the receiving groove 45 and is inserted into the card hole 22. In this process, the elastic card block 51 is pressed down and continues to move inward through the side of the limit buckle 46. When the bayonet plate 5 is inserted in place, the elastic card block 51 is just at the through hole, and resets and is stuck in the through hole under the action of elastic force. The limit buckle 46 limits and fixes the elastic card block 51, so that the entire bayonet plate 5 cannot be withdrawn, thereby connecting the upper cover 4 and the side plate 2 stably, so that the upper cover 4 cannot be directly lifted up. When it is necessary to open the upper cover 4, press the elastic card block 51 so that it is pressed under the limit buckle 46, and the elastic card block 51 is no longer stuck by the through hole. At this time, pull the bayonet plate 5 backward to extract it from the receiving groove 45, release the fixation of the upper cover 4 and the side plate 2, so that the upper cover 4 can be opened upward.

[0045] When the box body is folded and stored, the upper cover 4 can be stacked and stored separately, and multiple boxes and multiple upper covers 4 can be stacked separately.

[0046] The bottom of the receiving groove 45 is provided with a long groove, so that the elastic block 51 has enough movement space when being pressed down, and will not be unable to be pressed down due to direct contact with the bottom of the inner wall of the receiving groove 45.

[0047] One side of the elastic block 51 is an inclined surface, so that when the latch plate 5 is inserted, the inclined surface of the elastic block 51 contacts the edge of the limit buckle 46 and can be gradually pressed down. The other side is a flat surface, so that when it is located in the through hole, it can be pressed against the side wall of the through hole to achieve a limiting effect.

[0048] Elastic strips are arranged on both sides of the bayonet plate 5 . When the bayonet plate 5 is inserted into the receiving groove 45 , the elastic strips on both sides are squeezed and can press against the side walls of the receiving groove 45 under the action of elastic force to keep the bayonet plate 5 stable.

[0049] A pull ring is provided at the rear end of the bayonet plate 5 to facilitate pulling the bayonet plate 5 .

[0050] Furthermore, a stacking groove 47 is provided on the outer edge of the upper cover 4 , and a stacking block 12 which can be snapped into the stacking groove 47 is provided on the edge of the bottom plate 1 .

[0051] In this embodiment, the upper cover 4 is in a shape with a raised edge and a concave middle portion, and the middle portion of the bottom of the chassis 1 is in a shape of a downward protrusion that matches the upper cover 4, and can be just embedded in the concave portion in the middle portion of the upper cover 4, so that the chassis 1 of the upper box is just embedded in the upper cover 4 of the next box, and at the same time, the stacking block 12 on the edge of the chassis 1 is embedded in the stacking groove 47, so that the upper and lower boxes are tightly engaged to prevent displacement and collapse during the stacking process.

[0052] The device can be used as a conventional turnover box. It is made of PP material and is equipped with Fig.10In the case of the egg tray 7 shown, it can be used as a special egg turnover box, and concave egg grooves are arranged at intervals on the egg tray 7. An upwardly protruding support seat is arranged on the upper surface of the egg tray 7 in the intervals between the egg grooves. The bottom of the egg grooves of the upper egg tray contacts the support seat at the top of the lower egg tray to achieve up and down stacking, and the gap between the egg grooves below the upper egg tray 7 is used to accommodate the upper half of the eggs in the lower egg tray 8, that is, the egg grooves of the upper and lower egg trays 7 are staggered.
