These models have various usages, such as roasting chestnuts and, presumably other foods.
Most notably, they were used by the Triwizard Tournament champions who each drew small model dragons out of a silk bag prior to the First Task. The type of model indicated which dragon they had to face. A long time after the Second Task, the miniature figurine of Viktor Krum was seen trying to fight Harry Potter's dragon model at the Gryffindor Boys' Dormitory.
