The invention provides a spring tightening device for an aircraft refueling area illuminating lamp. The spring tightening device comprises a tightening assembly (1), a rotating shaft (2), a fixing plate (4) and a cylindrical pin (5). The tightening assembly (1) comprises a support (1a), a sector gear (1b) and two compression springs (1e). The rotating shaft (2) is fixedly arranged in an airplane,the sector gear (1b) penetrates through the rotating shaft (2) and can rotate around the rotating shaft (2), the sector gear (1b) makes contact with the two compression springs (1e), and when the sector gear (1b) rotates to enable the illuminating lamp to be in an on state, the compression springs (1e) provide elastic force for the sector gear (1b) to continuously push the sector gear (1b) to rotate. The structure is simplified, the size is reduced, the weight is reduced, a lamp holder base of the aircraft refueling area illuminating lamp is prevented from shaking under the flight aerodynamicload, and the tightening requirement when the aircraft refueling area illuminating lamp is turned off is met.
Description
technical field [0001] The invention belongs to the technology of locking structure design, and relates to a spring tightening device used for lighting lamps in aircraft refueling areas. Background technique [0002] At present, in order to meet the requirement that the lights in the refueling area of the aircraft need to be tightened and not shake under the flight aerodynamic load, the base of the lamp head of the lights in the refueling area of the aircraft should be tightened at the position of the aircraft skin without shaking. Due to the influence of the transmission gap when the lamp head is retracted, the traditional transmission structure cannot meet the requirements of tightening without shaking. [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 the base of the lamp head of the lighting lamp in the refueling area of the aircraft to be small i...
