Description
本实用新型涉及一种用于教学的印有暗射地图的充气地球仪。
目前中小学生做地理填充练习大多是在练习册上完成，局部的平面图形既无整体概念，又无立体感，且练习册只能一次性使用，不能反复进行填充练习。
本实用新型的目的在于提供一种可以反复进行地理填充练习、印有暗射地图的充气地球仪。
本实用新型的印有暗射地图的充气地球仪包括塑料薄膜球、堵盖和支座，塑料薄膜球表面印有暗射地图（即没有标地名的地图），其进气孔上装有堵盖，塑料薄膜球充气后安放在支座上。
本实用新型的优点是为中小学生做地理填充练习提供了一个理想的教学用具，既有整体概念，又有立体感，做完一次练习后，将笔迹擦掉，可反复多次地重复使用。
图1是本实用新型的结构示意图。
实施例：参见图1，本实用新型包括塑料薄膜球1、堵盖2和支座3，塑料薄膜球1由八块塑料薄膜热合而成，球表面印有暗射地图，球底的进气孔上装有堵盖2，支座3为弧形支架，由硬塑料制成。
