Referring to fig. 8 and 6, a variable plate 10 is connected to the diversion opening 5 in a limiting rotation manner, the variable plate 10 is a baffle plate with flow holes uniformly distributed, the position of the baffle plate limiting rotation point is on the upper half part of the baffle plate, a limiting block for limiting the baffle plate rotation angle range is arranged in the diversion opening 5, so that the baffle plate can only do rotation movement within a certain angle range, a balancing weight 11 is connected to the lower half part of the variable plate 10, as shown in fig. 8, in a normal state, the variable plate 10 is vertically downward, the balancing weight 11 is positioned below the variable plate 10, the upper end of the left side wall of the variable plate 10 is contacted with the limiting block, when the sealed cavity 6 sucks gas, the gas flow passes through the variable plate 10 from right to left, at this time, the variable plate 10 rotates clockwise to a horizontal position along the rotation point under the effect of the gas flow due to the great strength, the flow area of the diversion opening 5 is increased, so that the sealed cavity 6 can suck a large amount of gas rapidly, when the sealed cavity 6 exhausts, the airflow passes through the variable plate 10 from left to right, at the moment, the counterweight block 11 with relatively small airflow strength drives the variable plate 10 to reset under the action of gravity, meanwhile, the whole flow area is reduced, so that the airflow strength passing through the variable plate 10 is enhanced, and under the limitation of a limiting block, the variable plate 10 cannot rotate continuously along the resetting direction after self resetting due to the enhancement of the airflow strength, therefore, the sucked and flowed airflow can be adjusted through the variable plate 10, the flowing time of the airflow is prolonged, and the time required by cargo loading and unloading is met as much as possible.

Referring to fig. 2 and 3, the slow suction and release assembly 7 includes a sliding plate 71, an elastic restoring member 72 and a driving member 73, the sliding plate 71 is slidably and sealingly connected in the sealed chamber 6, the elastic restoring member 72 is connected between the sealed chamber 6 and the sliding plate 71, the driving member 73 is connected to the sliding plate 71, where the driving member 73 may be one or more, but it is necessary to connect to the balanced stress point of the sliding plate 71 whether there are more or one, for example, one driving member 73 is one, it is necessary to connect to the central point of the sliding plate 71, if there are more, it is necessary to connect to the central point as the reference point, uniformly and symmetrically on the central line of the sliding plate 71, to ensure that the sliding plate 71 can slide normally and smoothly in the sealed chamber 6, the driving member 73 includes a pulling rope 731, a spacing wheel 732 and an intermediate wheel 733, the spacing wheel 732 is fixedly and rotatably connected in the cabinet 1, the intermediate wheel 733 is slidably connected in the cabinet 1 and connected to the incomplete linkage assembly 8, one end of the pulling rope 731 is connected to the sliding plate 71, and the other end of the pulling rope 731 is fixedly connected to the cabinet 1 through the limiting wheel 732 and the intermediate wheel 733 in sequence, as shown in fig. 3, the section of the pulling rope 731 from the sliding plate 71 to the limiting wheel 732, the section of the limiting wheel 732 to the intermediate wheel 733, and the section of the intermediate wheel 733 to the cabinet 1 are all in a horizontal state, the distance for pulling the intermediate wheel 733 to drive the sliding plate 71 to slide through the pulling rope 731 is twice the moving distance of the intermediate wheel 733, and the sliding distance of the sliding plate 71 determines the suction amount of the gas in the sealed cavity 6.

Referring to fig. 4 and 5, a rotating shaft 12 is connected between the cabinet body 1 and the cabinet door 2, the incomplete linkage assembly 8 includes an incomplete gear 81, a reel 82, a connecting gear 83 and a connecting rope 84, two ends of the connecting rope 84 are respectively connected to the intermediate wheel 733 and the reel 82, the reel 82 is rotatably connected to the cabinet body 1, the connecting gear 83 and the incomplete gear 81 are respectively sleeved on the reel 82 and the rotating shaft 12, the connecting gear 83 is engaged with the incomplete gear 81, when the cabinet door 2 is opened, the incomplete gear 81 is driven to rotate by the rotating shaft 12, the incomplete gear 81 drives the reel 82 to rotate by the engaged connecting gear 83, the reel 82 winds the connecting rope 84 to drive the intermediate wheel 733 to slide in the cabinet body 1, the intermediate wheel 733 is pulled by the pulling rope 731 to slide in the sealed cavity 6 in the sliding process, and the elastic reset piece 72 is compressed and deformed, according to the piston principle, at this time, the gas is sucked into the sealed cavity 6 through the flow guide opening 5, when the cabinet door 2 is completely opened, the part without teeth on the incomplete gear 81 moves to the position of the previous meshing point with the connecting gear 83, at this time, the connecting gear 83 loses the meshing force and no longer drives the intermediate wheel 733 to continue to slide in the cabinet body 1 along the previous direction, and under the action of the elastic resetting piece 72, the connecting gear 83, the intermediate wheel 733 and the sliding plate 71 are all reset.

The working principle is as follows: when the heat-preservation energy-saving cold chain transportation refrigeration cabinet loads and unloads goods, firstly, the cabinet door 2 needs to be opened, in the process, the rotation of the rotating shaft 12 is utilized to drive the suction slow-release component 7 through the incomplete linkage component 8 to suck partial cold air flowing out in the door opening process of the refrigeration cabinet into the sealed cavity 6 through the flow guide port 5, as the whole cold air suction process is rigid, the sliding plate 71 can be driven to move to suck a large amount of cold air for standby, in the process of loading and unloading the goods after the cabinet door 2 is completely opened, according to the process, the sliding plate 71 performs reset motion under the action of the elastic component 72, so that the cold air sucked in the sealed cavity 6 is outwards discharged through the flow guide port 5, the flow guide port 5 outwards discharges to form a cold flow surface transversely cut based on the cold air flow discharging direction in the refrigeration cabinet, as shown in figure 9, the transversely cut cold flow surface can block the cold air in the refrigeration cabinet to a certain extent, the cold storage cabinet has the advantages of energy conservation and environmental protection, and compared with the prior art, the cold storage cabinet has the advantages of simple structure, convenience in use and good sealing performance.

Secondly, under the effect of cold flow surface, the air current that flows outside in the freezer can take place the backward flow to a certain extent, has correspondingly increased the activity of the inside air current of freezer, and then has accelerated the heat exchange rate of goods of packing into and cold air current, makes the goods of packing into can reach optimum cold storage state fast, has improved the cold-stored effect of goods relatively.

In addition, when the cabinet door 2 is opened, the sealing element 4 on the cabinet door is separated from the bar piece 3, the flow guide opening 5 on the bar piece 3 is exposed to carry out the suction and discharge of cold air, when the cabinet door 2 is closed, the bar piece 3 is embedded in the sealing element 4, at the moment, in addition to the sealing of the refrigerated cabinet through the sealing element 4, the sealing performance of the refrigerated cabinet can be further improved through the embedding clearance between the sealing element 4 and the bar piece 3, because part of the cold air of the refrigerated cabinet still spreads out from the clearance between the sealing element 4 and the refrigerated cabinet under the sealing of the sealing element 4, the spread cold air can flow out through the embedding clearance or flow into the flow guide opening 5, the flow speed of the cold air is further reduced by utilizing the embedding clearance, the sealing performance of the refrigerated cabinet is correspondingly improved, or the flow into the sealing cavity 6 through the flow guide opening 5 can cool the side edge of the refrigerated cabinet to a certain degree, accordingly, the heat preservation effect of the refrigerated cabinet is improved.
