[0002] In cold chain transportation, refrigerated trucks are often used for land transportation. During the transportation process, the temperature in the cargo compartment is lowered by a refrigerator to cool the goods in the cargo compartment, inhibit the growth of microorganisms in the goods, slow down respiration, and thus achieve the effect of prolonging the preservation of fresh and perishable goods.

[0003] However, the cold chain transportation in the prior art has the following problem, that is, the carriage is not necessarily fully loaded during each transportation, and the entire carriage needs to be refrigerated each time. In this way, the space without cargo also needs to be refrigerated, which easily causes energy waste. Therefore, an improved cold chain transportation auxiliary refrigeration device is needed to address this problem. Utility Model Content

[0006] Preferably, rubber strips are fixedly provided on both sides of the surface of the thermal insulation film, and a number of suction cups are evenly and fixedly provided on the outer surface of the rubber strips. The rubber strips can cooperate with the suction cups to be adsorbed and adhered to the inner side wall of the thermal insulation liner, thereby improving the sealing of both sides of the thermal insulation film, thereby improving the thermal insulation effect of the thermal insulation film and preventing cold air leakage.

[0007] Preferably, rubber pads are provided on the outer surfaces of the first connecting rod and the second connecting rod, and the rubber pads can improve the sealing performance of the first connecting rod and the second connecting rod against the inner side wall of the thermal insulation liner.

[0008] Preferably, the interior of the connecting sleeve is threadably screwed onto the outer surface of the screw, so that the rotatable connecting sleeve can drive the screw to move up and down when the connecting sleeve rotates, thereby driving the second connecting rod to move down or up, and driving the thermal insulation film to fold up when moving down, so that the auxiliary mechanism can be easily disassembled and the cargo can be loaded and unloaded into the car.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a cold chain transport auxiliary refrigeration device, including a carriage 1, a heat preservation liner 2 is fixedly arranged inside the carriage 1, a first air outlet 3 is fixedly arranged on one side of the heat preservation liner 2, and second air outlets 4 are fixedly arranged on both side walls of the heat preservation liner 2. An auxiliary mechanism for dividing the refrigeration space is arranged on one side of the heat preservation liner 2, and the auxiliary mechanism includes a first connecting rod 5, a telescopic rod 6, a second connecting rod 7, a heat preservation film 8, a screw 9, and a connecting sleeve 10. A first connecting rod 5 is arranged on one side of the heat preservation liner 2, and telescopic rods 6 are fixedly arranged on both sides of the upper end of the first connecting rod 5. The second connecting rod 7 is fixedly arranged on the upper end of the telescopic rod 6, and a heat preservation film 8 is fixedly arranged between the first connecting rod 5 and the second connecting rod 7. A screw 9 is fixedly arranged in the middle of the lower end of the second connecting rod 7, and a connecting sleeve 10 is movably arranged in the middle of the upper end of the first connecting rod 5 through a bearing.

[0021] The surface of the thermal insulation film 8 is fixedly provided with rubber strips 11 on both sides, and the outer surface of the rubber strips 11 is evenly and fixedly provided with a plurality of suction cups 12. The rubber strips 11 can cooperate with the suction cups 12 to be adsorbed and attached to the inner side wall of the thermal insulation liner 2, so as to improve the sealing performance of both sides of the thermal insulation film 8, thereby improving the thermal insulation effect of the thermal insulation film 8 and preventing cold air leakage;

[0022] The outer surfaces of the first connecting rod 5 and the second connecting rod 7 are both provided with rubber pads, and the rubber pads can improve the sealing performance of the first connecting rod 5 and the second connecting rod 7 against the inner side wall of the heat preservation liner 2;

[0023] The connecting sleeve 10 is movably screwed on the outer surface of the screw rod 9 through a threaded connection sleeve 10, so that the screw rod 9 can be driven to move up and down when the connecting sleeve 10 rotates, thereby driving the second connecting rod 7 to move down or up, and driving the thermal insulation film 8 to fold up when moving down, so that the auxiliary mechanism can be easily disassembled and the cargo can be loaded and unloaded into the carriage 1. When the second connecting rod 7 moves up, it can cooperate with the first connecting rod 5 to make the entire auxiliary mechanism tightly tensioned and fixed inside the thermal insulation liner 2;

[0024] A sealed door 13 is movably provided on one side of the surface of the carriage 1 through a hinge, and the sealed door 13 can protect the goods inside the carriage 1 and also prevent cold air from leaking and keep warm;

[0025] A lock buckle 14 is provided between the sealed box door 13 and the carriage 1 , and the lock buckle 14 can be used to lock the sealed box door 13 .

[0026] Working principle: When using this device, cold chain transportation can be carried out through the carriage 1, and cold air can be blown out through the first air outlet 3 and the second air outlet 4 in cooperation with the compressor and the refrigeration equipment, so that the inside of the heat preservation liner 2 can be cooled down to play the role of cold chain transportation (the compressor and the refrigeration equipment are not drawn in the figure, because they are mature existing technologies in cold chain transportation, so this application document does not elaborate too much);

[0027] The present device can freely divide the refrigeration space and the refrigeration mechanism according to the amount of transported goods. According to the amount of inventory, the auxiliary mechanism can be moved to a position near the goods, as close to the cargo pile as possible without interfering with the second air outlet 4. Then, the connecting sleeve 10 is rotated so that the connecting sleeve 10 causes the screw 9 and the second connecting rod 7 to move up under the action of the thread. In this way, the second connecting rod 7 can cooperate with the first connecting rod 5 to make the entire auxiliary mechanism tightly tensioned and fixed inside the thermal insulation liner 2; then, the rubber strip 11 can cooperate with the suction cup 12 to adhere to the inner side wall of the thermal insulation liner 2, so as to improve the sealing of both sides of the thermal insulation film 8. At this time, the refrigeration space can be reduced by the thermal insulation film 8, so that the entire refrigeration equipment only needs to cool the space between the thermal insulation film 8 and the first air outlet 3, so that the space of the compartment 1 without inventory can be divided outside the refrigeration range, which can save energy.

[0028] At the same time, if the amount of inventory inside the compartment 1 is very small, if the second air outlet 4 is outside the auxiliary mechanism when the auxiliary mechanism is installed, the second air outlet 4 can be closed so that the second air outlet 4 no longer blows out cold air;

[0029] When loading and unloading goods, the auxiliary mechanism of the device can be disassembled. During disassembly, the connecting sleeve 10 is reversed, so that the first connecting rod 5 and the second connecting rod 7 are close to each other and drive the insulation film 8 and the rubber strip 11 to bend and fold. In this way, the entire auxiliary mechanism can be disassembled to facilitate the loading and unloading of goods, and the whole operation process is convenient and quick.
