The invention provides a spring tightening device for lighting lights in aircraft refueling areas, comprising: a tightening assembly (1), a rotating shaft (2), a fixing plate (4) and a cylindrical pin (5); the tightening assembly (1) It includes: a bracket (1a), a sector gear (1b) and two compression springs (1e); the rotating shaft (2) is fixedly arranged in the aircraft, and the sector gear (1b) is set through the rotating shaft (2), and can be rotated around the rotating shaft (2) Rotate, the sector gear (1b) is in contact with two compression springs (1e) respectively, when the sector gear (1b) rotates to turn on the light, the compression spring (1e) provides the sector gear (1b) to continue to push the sector gear (1b) Elastic force of rotation. The structure is simplified, the volume is reduced, and the weight is reduced, which prevents the base of the lighting head of the aircraft refueling area from shaking under the flight aerodynamic load, and meets the requirement of tightening when the aircraft refueling area lighting is turned off.
Description
technical field [0001] The invention belongs to the locking structure design technology, and relates to a spring tightening device for a lighting lamp in an aircraft refueling area. Background technique [0002] At present, in order to meet the needs of the aircraft refueling area lighting that needs to be tightened and not shaken under the flight aerodynamic load, the base of the aircraft fueling area lighting lamp head should be tightened at the aircraft skin position without shaking. The traditional transmission structure cannot meet the requirement of tightening without shaking due to the influence of the transmission gap when the lamp cap is retracted and released. [0003] The structure of the existing tightening device is complicated and the volume is large, which cannot meet the requirements of the existing tightening device for tightening the base of the lamp base of the lighting lamp in the refueling area of the aircraft, which is small in size and can be tighten...
