[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown in the embodiment of this utility model, the foldable ventilated cold storage turnover box for cold chain packaging of apricots and plums includes a base 1. Folding plates 2 are rotatably fitted on the left and right inner sides of the base 1. Side plates 3 corresponding to the folding plates 2 are rotatably fitted on the front and rear inner sides of the base 1. Multiple ventilation holes 4 are opened in the middle of the two side plates 3. Openings 5 ​​are opened on opposite sides of the upper end of the two side plates 3. Slots 6 communicating with the openings 5 ​​are opened on opposite sides of the upper end of the two folding plates 2. Fixing components are installed in the multiple openings 5. The fixing components include an L-shaped locking block 7 that is elastically and slidably fitted in the opening 5, a rotating rod 8 that is rotatably fitted in the opening 5, and a push block 9 installed around the rotating rod 8 and corresponding to the inner side of the L-shaped locking block 7. One end of the L-shaped locking block 7 corresponds to the slot 6, and one end of the multiple L-shaped locking blocks 7 is provided with an arc surface.

[0027] In this embodiment, a base 1 is included;

[0028] Specifically, a placement groove 17 is provided in the middle of the base 1, and multiple round holes 18 connected to the placement groove 17 are provided on the upper side of the base 1. The multiple round holes 18 are connected to multiple ventilation holes 4. Through the multiple ventilation holes 4, the air inside the turnover box is exchanged with the outside air, thereby promoting air circulation and ensuring the freshness of the apricots during transportation.

[0029] Specifically, ice packs 19 are installed in the placement slot 17, and a baffle 20 corresponding to the placement slot 17 is rotatably fitted on one side of the base 1. Universal wheels 21 are installed at the four opposite corners of the lower side of the base 1. The ice packs 19 can reduce the temperature inside the turnover box and keep the apricots fresh.

[0030] In this embodiment, the left and right inner sides of the base 1 are rotatably fitted with folding plates 2, and the front and rear inner sides of the base 1 are rotatably fitted with side plates 3 corresponding to the folding plates 2. Multiple ventilation holes 4 are opened in the middle of the two side plates 3, openings 5 ​​are opened on the opposite sides of the upper end of the two side plates 3, and slots 6 connected to the openings 5 ​​are opened on the opposite sides of the upper end of the two folding plates 2.

[0031] Specifically, the folding plate 2 includes a first plate 14 rotatably fitted to the inner side of the base 1 and a second plate 15 rotatably fitted to the upper end of the first plate 14, and two slots 6 are located on opposite sides of the second plate 15. By rotating the second plate 15 at the upper end of the first plate 14, the included angle between the first plate 14 and the second plate 15 can be changed, thereby unfolding or folding the folding plate 2.

[0032] Specifically, the upper ends of the two second plates 15 and the two side plates 3 are equipped with movable covers 16, and the size of the movable covers 16 is larger than the size of the base 1. By making the size of the movable covers 16 larger than the size of the base 1, the movable covers 16 can completely cover the base 1, effectively reducing unnecessary space occupation.

[0033] In this embodiment, a fixing component is installed in each of the multiple openings 5. The fixing component includes an L-shaped locking block 7 that is elastically and slidably fitted in the opening 5, a rotating rod 8 that is rotatably fitted in the opening 5, and a push block 9 installed on the periphery of the rotating rod 8 and corresponding to the inner side of the L-shaped locking block 7. One end of the L-shaped locking block 7 corresponds to the slot 6, and one end of each of the multiple L-shaped locking blocks 7 is provided with an arc surface.

[0034] Specifically, the fixing components also include a spring 10 installed inside the opening 5, a slide groove 11 opened at the bottom of the opening 5, a slider 12 installed at the lower end of the L-shaped block 7, and a turntable 13 installed at one end of the rotating rod 8. The spring 10 can drive the L-shaped block 7 to elastically extend and retract and automatically return to its original position, so that one end of the L-shaped block 7 is engaged with the slot 6, thereby fixing the two folding plates 2 and the two side plates 3 together, making them a whole.

[0035] Specifically, one end of the spring 10 is fixedly connected to the other end of the L-shaped block 7, the slider 12 is slidably fitted in the groove 11, and the turntable 13 is rotated and fitted at the upper edge of the side plate 3. Through the turntable 13, the rotating rod 8 can be driven to rotate, so that the push block 9 pushes the other end of the L-shaped block 7, thereby canceling the engagement between one end of the L-shaped block 7 and the groove 6, and canceling the assembly between the two folding plates 2 and the two side plates 3.

[0036] Working steps: 1. When the turnover box needs to be folded, lift the movable cover 16 upwards and place it on the ground. Then rotate multiple turntables 13, which will drive the rotating rods 8 to rotate. This will cause the multiple rotating rods 8 to drive multiple push blocks 9 to rotate, thereby pushing the inner sides of multiple L-shaped locking blocks 7. At this time, multiple springs 10 will elastically extend and retract simultaneously, and multiple sliders 12 will slide and engage with multiple grooves 11. This will cause one end of the multiple L-shaped locking blocks 7 to disengage from the multiple locking grooves 6 and retract into the multiple openings 5, thereby releasing the fixed connection between the two folding plates 2 and the two side plates 3. Then, by rotating the two second plates 15, the angle between the two second plates 15 and the two first plates 14 can be changed, so that the two second plates 15 and the two first plates 14 remain parallel, thereby folding the two folding plates 2. Then, rotate the two folding plates 2 and the two side plates 3 after folding. At this time, the two folding plates 2 and the two side plates 3 after folding remain parallel to the base 1. At the same time, the base 1 stores the two folding plates 2 and the two side plates 3 after folding. Then, cover the base 1 with the movable cover 16 to realize the folding and storage of the turnover box.

[0037] 2. When it is necessary to assemble the turnover box, lift the movable cover 16 upward and place it on the ground. Then, rotate the two folded plates 2 and the two side plates 3 in the opposite direction. At this time, the two folded plates 2 and the two side plates 3 are perpendicular to the base 1. At the same time, rotate the two second plates 15 in the opposite direction to change the angle between the two second plates 15 and the two first plates 14, thereby unfolding the two folded plates 2. Then, move the two side plates 3 closer to the two unfolded folded plates 2. At this time, multiple arc-shaped surfaces press against the opposite sides of the two unfolded folded plates 2, which can drive multiple L-shaped blocks 7 to retract into multiple openings 5. When multiple openings 5 ​​are aligned with multiple slots 6, multiple springs 10 drive multiple L-shaped blocks 7 to elastically extend and return to their original positions, so that multiple L-shaped blocks 7 simultaneously extend into multiple slots 6 and form a locking relationship with them, thereby fixing the two folded plates 2 and the two side plates 3. Then, cover the upper ends of the two folded plates 2 and the two side plates 3 with the movable cover 16 to realize the assembly of the turnover box.

[0038] 3. When it is necessary to transport apricots and plums in a fresh condition, first place the apricots and plums inside the turnover box, then rotate the baffle 20 to open the placement slot 17, then put the ice pack 19 into the placement slot 17, and rotate the baffle 20 in the opposite direction to close the placement slot 17. At this time, the ice pack 19 can lower the temperature inside the placement slot 17. At the same time, the cold air generated by the ice pack 19 enters the interior of the turnover box through multiple round holes 18, which can lower the temperature inside the turnover box and achieve the preservation of apricots and plums. Meanwhile, the air inside the turnover box exchanges with the outside air through multiple vent holes 4, thereby promoting air circulation and ensuring the preservation effect of apricots and plums during transportation.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
