Description

Technical Field

[0001] The utility model relates to the technical field of fixing devices, in particular to a fixing device for a box-type refrigerated semi-trailer. Background Art

[0002] A semi-trailer is a trailer with an axle placed behind the center of gravity of the vehicle (when the vehicle is evenly loaded) and equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. Semi-trailer refrigerated trucks are more professional models, special vehicles for special purposes. Sometimes, if the temperature of the goods to be pulled needs to reach about minus 5-15 degrees, a box-type semi-trailer refrigerated truck must be used. There are many subdivisions, and the requirements of refrigerated trucks for different transport goods are also different: roughly: Refrigerated trucks for preservation, generally used for fresh fruits, seafood, milk, etc.; Refrigerated trucks for freezing: generally used for frozen product transportation. High-risk goods refrigerated trucks: generally used for chemical transportation, vaccine transport trucks: generally used for medical systems.

[0003] When currently available refrigerated semi-trailers are transporting goods, the staff generally place the goods in piles in the cargo hold. When there is less cargo, the cargo box cannot be connected to the cargo hold walls on both sides. During transportation by a van, the speed is relatively fast and sudden braking may occur during driving. Sudden braking will cause the box equipped with the goods to shake violently, causing the stacked goods to scatter and cause internal damage. In addition, during the transportation process of the vehicle, the goods may collide with each other during the bumpy process, causing damage to the goods. Utility Model Content
