[0021] Please see Figures 1-4 This utility model provides a technical solution: a door sealing device for a refrigerated semi-trailer, comprising: a door 2 and a sealing glass 3; the door 2 is symmetrically arranged at the rear end of the refrigerated compartment 1, and the sealing glass 3 is fixedly embedded in the side wall of the door 2, and a sealing adhesive layer 4 is adhered to the side of the sealing glass 3; auxiliary components are provided on the door 2.

[0022] The sealed glass 3 on the door 2 allows personnel to directly observe and monitor the condition of the goods from the outside of the refrigerated compartment 1 of the refrigerated semi-trailer. The sealed glass 3 is further reinforced with a sealing layer 4 to ensure the sealing effect.

[0023] The rotating rod 5 is rotatably mounted on the door 2 and located diagonally above the sealed glass 3. Both ends of the rotating rod 5 penetrate the side wall of the door 2. One end of the rotating rod 5 is connected to a handle 6, and the other end of the rotating rod 5 is connected to a fixing plate 7. The handle 6 and the fixing plate 7 are arranged in parallel.

[0024] The handle 6 is located on the outside of the door 2. A first knob bolt 8 is threadedly connected to the side wall of the handle 6. A positioning block 9 is connected to the end of the first knob bolt 8. A positioning slot 10 is opened on the side wall of the door 2. The positioning block 9 is inserted into the positioning slot 10.

[0025] Adjust the position of the fixing plate 7 by rotating the outer handle 6, and rotate the first knob bolt 8 to control the positioning block 9 at the end of the first knob bolt 8 to be inserted into the positioning slot 10 on the door 2 to fix the position of the handle 6 and the fixing plate 7.

[0026] The fixing plate 7 is located inside the door 2. A trapezoidal mounting groove 11 is provided on the side wall of the fixing plate 7. A trapezoidal mounting plate 12 is embedded in the trapezoidal mounting groove 11. A wiping plate 13 is connected to the side wall of the trapezoidal mounting plate 12.

[0027] A wiping cloth 14 is connected to the side wall of the wiping plate 13. The wiping cloth 14 is in contact with the sealing glass 3.

[0031] Working principle: After the trapezoidal mounting plate 12 is engaged with the trapezoidal mounting groove 11, the slider 17 moves along the slide groove 15 to adjust the movement of the U-shaped limiting plate 16 to lock and limit the trapezoidal mounting plate 12. The second knob bolt 18 is controlled to move and insert into the insertion hole 19 to fix the position of the U-shaped limiting plate 16. Then, the wiping plate 13 is installed on the fixed plate 7. Rotating the first knob bolt 8 controls the positioning insert 9 to separate from the positioning slot 10 on the door 2 and unlock the handle 6. By rotating the handle 6, the fixed plate 7 is rotated, so that the wiping cloth 14 wipes the water mist on the sealing glass 3. Through the sealing glass 3 on the door 2, it is convenient for personnel to directly observe and monitor the condition of the goods from the outside of the refrigerated compartment 1 of the refrigerated semi-trailer. This avoids the frequent opening of the compartment 2 to monitor the condition of the goods during long-distance transportation of goods by the refrigerated semi-trailer, thereby reducing the wear of the sealing strip at the connection between the compartment door and the compartment.
