Evaporation type air cooling unit

The utility model relates to the technical field of fixing devices, and discloses an evaporative air cooler unit which comprises a fixing base, universal wheels are fixedly connected to the four corners of the bottom of the fixing base, a shock pad is movably connected to the top of the fixing base, and an air cooler base is fixedly connected to the top of the shock pad. According to the evaporation type air cooler unit, when the air cooler body needs to be fixed, the air cooler base is placed above the fixed base and moved to the inner sides of the fixed clamping blocks, the air cooler base can be primarily limited and fixed through the limiting pins and the limiting grooves, and the air cooler base can be fixed through rotation of the manual rocking handle in the rotating process of themanual rocking handle. When the air cooler is used, the threaded rod is driven to rotate, the positioning block and the positioning pin are sequentially driven to move up and down in the rotating process of the threaded rod,
