Rapid deflection angle measuring device

The utility model discloses a device for rapidly measuring deflection angles of blades on an inner layer and an outer layer of a cabin ventilation opening. The device comprises a fixed support, a measuring foot, a sliding block, a fixed bolt and a digital display dipmeter. The fixing support is placed on a ventilation opening panel, nuts of the first clamping block and the second clamping block at the two ends of the cross beam are screwed to fix the fixing support and the ventilation opening panel, the digital display dipmeter fixed to the measuring foot moves along with the sliding block, and when the sliding block is moved to a proper measuring position, the lower end of the measuring foot is inserted into a ventilation opening blade. And after being fixed by the fixing bolt, the deflection angle of the cabin ventilation opening is measured by the digital display dipmeter, so that the aim of quickly measuring the deflection angle of the cabin ventilation opening is fulfilled. 本实用新型公开了一种用于快速测量座舱通风口内、外层叶片偏摆角
