[0014] like Figures 3 to 4 As shown, a heat insulation strip for a refrigerated truck door frame is provided. The heat insulation strip 3 is a long strip of heat insulation material. Its upper part has two stepped surfaces, the lower stepped surface of which is the door frame connecting surface 8, and multiple rivet holes 7 are evenly distributed on the door frame connecting surface 8. The lower part of the heat insulation strip 3 is the inner panel connecting surface 9 of the truck body. like Figure 2 As shown, the door frame connecting surface 8 of the heat insulation strip 3 is fixedly connected to the inner side plate of the vehicle door frame 2 by a plurality of rivets 6 that pass through the rivet holes 7. like Figure 2 As shown, the inner panel connecting surface 9 of the heat insulation strip 3 is tightly attached to the inner panel skin of the vehicle body panel 1; In the above implementation scheme, the heat insulation strip 3 is a long strip of heat insulation material, and its length can be arbitrarily cut according to the needs of use. When installing the heat insulation strip 3, the end of the heat insulation strip 3 with the door frame connecting surface 8 is inserted into the reserved gap between the vehicle body panel 1 and the vehicle body door frame 2. The door frame connecting surface 8 of the heat insulation strip 3 is fixedly connected to the inner side panel of the vehicle body door frame 2 by a plurality of rivets 6 that pass through the rivet holes 7. The inner panel connecting surface 9 of the heat insulation strip 3 is tightly attached to the inner panel skin of the vehicle body panel 1.
