[0002] When transporting fresh vegetables, they are usually placed in storage boxes. These boxes are equipped with cooling pads to control the temperature inside, thereby increasing the preservation effect of the vegetables. However, the top of the box is usually fixed to the box with a latch. Over time, the latch is prone to wear and tear, which can cause it to loosen and reduce the sealing effect of the box lid. Therefore, we propose a fresh vegetable transport and storage device. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this patent is to provide a device for transporting and storing fresh vegetables. This patent features ear plates installed at both ends of the lid and fixing rings installed on both sides of the body. The top of the fixing rings is equipped with a pressure plate controlled by a spring. The elasticity of the spring allows the bottom of the pressure plate to press against the top of the ear plate, thereby achieving a sealed assembly between the lid and the body.

[0018] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0019] See Figure 1 , Figure 2 , Figure 3 and Figure 4This is a schematic diagram of the structure of this patent. A fresh vegetable transportation and storage device includes a box body 1, a box cover 2 fastened to the top of the box body 1, an insulation layer 3 provided on the inner side wall of the box body 1 and the bottom of the box cover 2, a cooling plate 4 embedded in the middle of the box cover 2, and a thermostat 5 fixedly installed on the top right side of the box cover 2. The thermostat 5 is electrically connected to the cooling plate 4.

[0020] The bottom of the cooling element 4 is the cold side, which is used to cool the inside of the cabinet 1, and the top is the hot side.

[0021] The refrigeration element 4 is a CP14-127-10 type semiconductor refrigeration element.

[0022] The thermostat 5 is a PRD-C6(7)000 type thermostat.

[0023] The temperature of the cooling element 4 can be detected and controlled by the thermostat 5, as detailed in Chinese Patent CN202222297917.5.

[0024] Both ends of the lid 2 are integrally formed with ear plates 6. Both ends of the outer side wall of the box body 1 are integrally formed with fixing rings 7. The inner side wall of the fixing rings 7 is slidably installed with uprights 8. The bottom end of the uprights 8 is integrally formed with a circular plate 9. A spring 10 is sleeved on the side wall of the uprights 8. The bottom end of the spring 10 is fixedly installed on the top of the circular plate 9. The top end of the spring 10 is tightly fitted to the bottom of the fixing rings 7. The top end of the uprights 8 is fixedly installed with a pressure plate 11. The bottom of the pressure plate 11 is tightly fitted to the top of the ear plates 6.

[0025] Figure 1 The spring 10 shown is in a compressed state. The compression effect of the spring 10 can press the bottom of the pressure plate 11 against the top of the ear plate 6.

[0026] The top of the spring 10 is only attached to the bottom of the fixed tube 7 and there is no installation relationship, which makes it convenient for the upright 8 to rotate, so that the pressure plate 11 can rotate and detach from the top of the ear plate 6, making it easy to remove the box cover 2.

[0027] Specifically, the insulation layer 3 includes a foam layer 12 and a protective layer 14. An adhesive layer 13 is provided on the outside of the foam layer 12, and the outside of the foam layer 12 is connected to the protective layer 14 through the adhesive layer 13.

[0028] The protective layer 14 can be a non-woven fabric layer or a plastic layer, used to protect the foam layer 12 and prevent the internal vegetables from scratching the foam layer 12.

[0029] Specifically, the fixing ring 7 includes a ring body 15 and a bearing 16. The outer side wall of the ring body 15 is integrally formed on the outer side wall of the housing 1. The inner side wall of the ring body 15 is fixed to the outer side wall of the outer ring of the bearing 16. A connecting ring 17 is fixedly installed at the bottom of the inner ring of the bearing 16. The bottom of the connecting ring 17 is fixedly installed on the top of the spring 10.

[0030] If the top of the spring 10 is directly attached to the bottom of the fixed ring 7, the top of the spring 10 will experience severe friction and wear against the bottom of the fixed ring 7 when the upright rod 8 is rotated.

[0031] By setting the bearing 16, relative rotation can occur between the ring 15 and the spring 10.

[0032] Specifically, the inner wall of the inner ring of bearing 16 does not contact the side wall of the upright 8.

[0033] Specifically, the top of the ear plate 6 is provided with a positioning groove 18, and the bottom of the pressure plate 11 is integrally formed with a positioning rod 19, which is inserted into the positioning groove 18.

[0034] The positioning rod 19 is inserted into the positioning groove 18 to increase the fixing effect of the pressure plate 11 on the ear plate 6.

[0035] Specifically, the bottom end of the positioning rod 19 is provided with a tapered surface 20.

[0036] like Figure 4 As shown, the tapered surface 20 reduces the size of the bottom end of the positioning rod 19, making it easier for the bottom end of the positioning rod 19 to be inserted into the positioning groove 18.

[0037] Working principle: such as Figure 1 As shown, when disassembling the box cover 2, the circular plate 9 can be moved upward to disengage the positioning rod 19 from the positioning groove 18. Then, the circular plate 9 can be rotated to disengage the pressure plate 11 from the upper position of the ear plate 6. The box cover 2 can then be removed, and the vegetables to be transported can be placed inside the box body 1. The box cover 2 can then be fastened and closed again. The cooling element 4 can be controlled by the thermostat 5 to cool the inside of the box.

[0038] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent. In terms of the technical aspects of this design principle, the setting of the device's power mechanism, power supply system and control system is not fully described. However, those skilled in the art who understand the principle of the above patent can clearly understand the specifics of its power mechanism, power supply system and control system.

[0039] This patent features ear plates installed on both the left and right ends of the lid and fixing rings installed on both the left and right sides of the box body. The top of the fixing rings is equipped with a pressure plate controlled by a spring. The elasticity of the spring allows the bottom of the pressure plate to press against the top of the ear plate, thereby achieving a sealed assembly between the lid and the box body. Through the above connection structure, wear between components is minimal, effectively preventing the phenomenon of poor sealing due to long-term use.
