Description

Technical Field

[0001] The present invention relates to a transport box, in particular to a cold chain logistics transport cold-keeping box. Background Art

[0002] Cold chain logistics and transport cooler containers are designed specifically for transporting temperature-sensitive goods. They utilize a sandwich-structured composite insulation layer (such as polyurethane or vacuum insulation panels) and a sealed door design, along with phase change materials or an electronic temperature control system, to precisely maintain a low-temperature environment within the container, ranging from -40°C to 8°C. Widely used in applications such as pharmaceutical vaccines, fresh food, and biological samples, these containers ensure consistent quality throughout the entire cold chain transport process, guaranteeing a continuous supply chain.

[0003] At present, in existing cold-keeping boxes, the active refrigeration plates or condensing tubes in the box can only be set at the bottom of the box, and the box walls are in the form of insulation plates. When the cold-keeping box is used to transport items, there is an uneven distribution of temperature. There is a temperature difference between the top and bottom of the items in the box, which makes it easy for local temperature fluctuations to occur in the box, affecting the quality of frozen food. At the same time, the existing spring shock-absorbing components are insufficient to absorb vibrations under bumpy road conditions. Vibrations may still be transmitted to the box through the rigid structure, resulting in an increase in the cargo damage rate. Summary of the Invention

[0004] In order to overcome the shortcomings of existing transport cold-keeping boxes that only actively cool the bottom, resulting in temperature differences between the items in the box and the bottom, affecting the quality of the cold chain, and the lack of fixing devices in the box, which makes the items easy to move or tip over, the technical problem to be solved is: to provide a cold chain logistics transport cold-keeping box with multi-directional refrigeration and fixing mechanisms.

[0005] The technical implementation scheme of the present invention is: a cold chain logistics transportation cold preservation box, including a box body, a box cover, a refrigeration plug-in plate, a condensation water tank, a return water tank, a pump and a condensation water pipe. The box cover is rotatably connected to the box body by a hinge, and a slot is provided on the inner wall of the box. The refrigeration plug-in plate is slidably embedded in the slot. The condensation water tank and the return water tank are fixed to the outside of the box body by a snap connection. The condensation water tank and the return water tank are connected by a condensation water pipe. The condensation water pipe is evenly coiled and fixed to the slot and the bottom of the box body. A pump is provided at the middle end of the condensation water pipe to drive the water flow. The bottom and inner wall of the box are both provided with an insulation pad, and also include a screw, a hinge block, a limit flap and a buffer piston cylinder.

The hinge block is mounted on the screw through a threaded sleeve, and the hinge block slides longitudinally on the inner wall of the box. The limit flap is rotatably connected to the hinge block through a hinge. The height of the hinge block is adjusted by rotating the screw, and then the limit flap is rotated and closed to seal and separate the inner cavity of the box. A buffer piston cylinder is provided on the inner bottom surface of the box cover, which can press and fix the limit flap.

[0039] Working principle: The present invention adopts a detachable refrigeration plug-in board 4 for active refrigeration, and then drives the condensed water circulation through the pump 7 to achieve uniform cold chain cold preservation. Specifically, a DC power supply is provided in the box body 1, and the refrigeration plug-in board 4 is powered by the socket in the slot 101. The refrigeration plug-in board 4 is a semiconductor refrigeration board. Through the action of DC power on special semiconductor materials (such as PN junction), heat absorption and heat release phenomena are generated at both ends of the galvanic couple, thereby achieving refrigeration. The refrigeration plug-in board 4 arranged on the inner wall of the box body 1 can efficiently cool the box body 1. The front and rear sides of the outside of the box body 1 are respectively provided with condensation water tank 5 and return water tank 6 placement sockets, which are also fixed by sliding card connection. The condensation water tank 5 and the return water tank 6 are both provided with a one-way valve on the side close to the box body 1, so that the condensation After the water tank 5 and the return water tank 6 are fixed, they can form a passage with the condensation water pipe 8. After the pump 7 is started (the power supply of the pump 7 is provided by the above-mentioned DC power supply, and the pump 7 is provided with a switch located outside the box body 1), a water pressure difference is formed in the condensation water pipe 8, and then the condensation water flows in the condensation water pipe 8, and the cold air of the refrigeration plug board 4 is diffused through the heat transfer effect. At the same time, the refrigeration is evenly performed through the tortuous and coiled arrangement effect. A detachable refrigeration plug board 4 and the condensation water tank 5 are provided to provide a flexible maintenance and replacement solution. The positioning plug board 22 can fix the condensation water tank 5 and the return water tank 6. The water flow formed in the condensation water pipe 8 can impact the water wheel blades 1401, and the water wheel blades 1401 will replace the air inside and outside the box to achieve a rapid cooling effect. It is worth noting that the circulation A rotating cover is provided on the outside of the annular fan 14. When the water wheel blades 1401 rotate, the wind pushes the cover open, and when the water wheel blades 1401 are stationary, the cover is closed, which can maintain the sealing of the box body 1. After the staff puts the items to be transported in the box body 1, in order to reduce the space in the box, the screw 10 can be rotated by twisting the ring 1001, and the height of the hinge block 11 can be adjusted by the screw 10. When the height of the hinge block 11 is flush with the upper edge of the item, the limit flap 12 is rotated to separate the inner cavity of the box body 1, and at the same time, the storage of items is limited. It not only provides a variety of ways to place items separately, but also improves the stability of items during transportation. The buffer piston cylinder 13 at the bottom of the box cover 2 can suppress the limit flap 12 or the item to further improve the The present invention provides a convenient combination method for improving the stability of the boxes 1 and 1, and is provided with a docking protrusion 18 and a docking recess 19 that can slide longitudinally and engage with each other. The docking protrusion 18 is slidably arranged in the limiting slide 17 on the left side of the box 1, and the docking recess 19 is slidably arranged in the limiting slide 17 on the right side of the box 1. The staff only needs to bring the two boxes 1 close to each other horizontally, and then move the docking protrusion 18 or the docking recess 19 down and reset it. The docking protrusion 18 and the docking recess 19 can be engaged in an engaging manner to combine and fix the adjacent boxes 1, thereby providing a high-stability fixing method for combining multiple boxes 1 with each other. The loading and unloading or transportation of the boxes 1 can be carried out by the telescopic pull rod 3. If there are many items in the box 1,The pedal 1601 of the control panel 16 can be kicked horizontally, so that the wedge-shaped push block 1602 of the control panel 16 contacts and pushes the movable wheel seat 15 downward. When the movable wheel seat 15 moves below the base 102, it can prop up the box 1. At this time, the staff can use the movable wheel seat 15 to move the box 1 horizontally, which improves the convenience of transporting the box 1.
