Description

Technical Field

[0001] This utility model relates to the field of insulated boxes, and in particular to a foldable food cold chain insulated box. Background Technology

[0002] In the food delivery and fresh produce distribution industry, insulated food cold chain boxes are a core tool for ensuring the quality of meals and fresh produce. However, existing insulated boxes have significant shortcomings in dealing with liquid leakage scenarios: when delivering orders containing soup, beverages, or fresh produce (such as seafood and fruit), soup and condensation easily accumulate inside the box. Traditional insulated boxes lack convenient drainage designs, requiring the contents to be emptied before liquids can be poured out, which is cumbersome and easily contaminates the environment inside the box.

[0003] Traditional insulated boxes typically lack a dedicated drainage structure. If liquid leaks, the food, fresh produce, and other items must be removed one by one before the box is turned upside down to empty the liquid, making cleaning quite troublesome and reducing delivery efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing insulated boxes usually lack a dedicated drainage structure, and after liquid leakage, it is necessary to take out the meals, fresh food and other items one by one, and then turn the box over to pour out the liquid, which is quite troublesome and leads to a decrease in delivery efficiency. Therefore, a foldable food cold chain insulated box is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foldable food cold chain insulation box, comprising a telescopic foldable insulation sleeve, a base plate fixedly connected inside the telescopic foldable insulation sleeve near the bottom, a ring plate fixedly connected inside the telescopic foldable insulation sleeve near the top, first U-shaped pieces fixedly connected to the bottom of the base plate near the four corners and the top of the ring plate near the four corners, a first support plate embedded and pin-connected inside the first U-shaped piece on the ring plate, and a second support plate embedded and pin-connected inside the first U-shaped piece on the base plate, the first support plate... The base plate and the second support plate are connected by a pin. The top of the base plate and the bottom of the ring plate are symmetrically provided with grooves. A sliding rod passes through the grooves. Both ends of the sliding rod are fixedly connected to the inner wall of one end of the groove. A slider is fitted and slidably connected to the surface of the sliding rod. A second U-shaped piece is fixedly connected to the surface of the slider. A cross-shaped piece is pin connected between the second U-shaped pieces. A square groove is provided at the top of the base plate. An annular groove is provided at the top of the base plate and at the edge of the square groove. A mesh plate is embedded inside the annular groove. A drain hole is provided on the bottom inner wall of the square groove near one corner.

[0006] Preferably, a groove is provided on one side wall of the first support plate near the bottom, and a panel is embedded inside the groove. The panel is fixedly connected to the top of the second support plate.

[0007] Preferably, a circular groove is provided at the bottom of the base plate and at the drain hole, and a screw cap is embedded and threaded into the inside of the circular groove. Circular blocks are fixedly connected at equal intervals at the bottom of the screw cap and near its edge.

[0008] Preferably, the top of the telescopic folding insulation sleeve is provided with a top cover, one end of which is fixedly connected to the telescopic folding insulation sleeve, and the other three sides of which are connected to the zipper of the telescopic folding insulation sleeve.

[0009] Preferably, a handle is fixedly connected to the top of the top cover near the center.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, the design of the drain hole and screw cap means that after liquid leakage, there is no need to empty the contents of the box. The accumulated liquid can be discharged by simply unscrewing the screw cap, which can improve the efficiency of cleaning liquid and thus reduce hygiene hazards.

[0012] 2. In this utility model, the telescopic folding insulation sleeve, combined with the ring plate, cross-shaped parts and other structures, can fold the insulation box, thereby facilitating the storage of delivery vehicles and rider backpacks. Attached Figure Description

[0024] Working principle: Before delivery, the telescopic folding insulation sleeve 1 is stretched. The first U-shaped piece 4 causes the insert 8 on the second support plate 6 to be embedded in the groove 7 on the first support plate 5. At the same time, the slider 11 slides on the surface of the slide rod 10, causing the second U-shaped piece 12 to drive the cross-shaped piece 13 to open synchronously, forming a rectangular insulation cavity. The ring plate 3 and the bottom plate 2 are fixed by the slot to build a closed space. At this time, the top cover 21 can be opened to place the delivered items on the mesh plate 16. When the food contains liquid, after the soup leaks, it will be filtered by the mesh plate 16 (solid residue on the mesh plate 16), and the liquid will enter the square groove 14. When the screw cap 19 is opened, the liquid can be discharged from the drain hole 18. After cleaning, the screw cap 19 is tightened to restore the seal. When refrigeration is needed, ice cubes can also be placed in the square groove 14. After delivery, the cross-shaped piece 13 is pressed to unlock, and the slider 11 is pushed to slide along the slide rod 10, causing the support plate and the cross-shaped piece 13 to fold and retract. The telescopic folding insulation sleeve 1 is compressed accordingly and finally folded into a flat shape.

[0025] The wiring diagram of the telescopic folding insulation sleeve 1 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the telescopic folding insulation sleeve 1 will not be explained in detail.
