Description

Technical Field

[0001] The invention relates to a lifting and unlocking structure with multiple lighting colors for a landing gear operating switch handle. Background Art

[0002] The landing gear control switch is a special switch used to control the retraction and lowering of the aircraft landing gear. The landing gear switch handle is generally designed with one lighting color - night vision red, and the landing gear handle is lit during the retraction and lowering of the landing gear.

At the same time, the current mainstream fighters use dual-mode lighting - night vision green and blue-white light mode switching. Therefore, it is urgent to improve the control mechanism of the existing landing gear control switch and design a pull-unlocking structure with multiple lighting colors (3 colors).

[0030] The bottom of the handle seat 7 has a handle lower connecting portion 73. In this embodiment, the handle lower connecting portion 73 is a cylindrical through hole that passes through the bottom of the handle seat 7. The handle lower connecting portion 73 has a handle coupling hole extending in the lateral direction.

[0031] The top of the sliding sleeve body 8 has a sliding sleeve connecting portion 81. In this embodiment, the sliding sleeve connecting portion 81 is a cylindrical protrusion extending upward from the top surface of the sliding sleeve body 8. The sliding sleeve connecting portion 81 has a sliding sleeve coupled hole. The sliding sleeve connecting portion 81 extends into the lower connecting portion 73 of the handle, and the bottom surface of the handle seat 7 abuts against the top surface of the sliding sleeve body 8. A connecting screw is provided between the handle coupling hole and the sliding sleeve coupled hole. The interior of the sliding sleeve body 8 has an accommodating space 80. The accommodating space 80 is sequentially divided into a first section, a second section and a third section from top to bottom. The inner diameter of the first section is smaller than the inner diameter of the second section. The inner diameter of the second section is smaller than the inner diameter of the third section.

[0032] The lower end of the sliding sleeve body 8 has a connecting hole extending laterally.

[0033] The upper end of the guide rod 9 enters the third section from the lower end of the sliding sleeve body 8. The guide rod 9 has an adjustment hole. The adjustment hole extends in the up-down direction. In this embodiment, the adjustment hole is a long waist-shaped hole. The length of the adjustment hole is the relative sliding space between the guide rod 9 and the sliding sleeve body 8.

[0034] The connecting shaft passes through the connecting hole of the sliding sleeve body 8 on one side, the adjusting hole on the displacement side, the adjusting hole on the other side, and the connecting hole of the sliding sleeve body 8 on the other side in sequence. Both ends of the connecting shaft have shaft sleeves.

[0037] The thin optical fiber 4 passes through the guide rod channel, the accommodating space, the optical fiber passing hole of the limiting seat in sequence, and extends to the diffusion plate.

[0038] The thick optical fiber 3 and the thin optical fiber 4 are bundled into one body by a binding wire in the cover handle section. The thick optical fiber 3 and the thin optical fiber 4 are outside the guide rod 9.

[0039] In this embodiment, the number of the thick optical fiber 3 is 1, and the number of the thin optical fibers 4 is 8.

[0040] According to the needs of external signals, the lighting color of the light-transmitting column is adjusted to night vision green or blue-white light. Eight thin optical fibers emit light through the night vision red module of the fiber optic light source board and transmit the light to the diffuser to diffuse the light, making the light more uniform, and then irradiate the outer surface of the light-transmitting cover. According to the needs of external signals, the lighting color of the light-transmitting cover is adjusted to night vision red. The fiber optic light source board effectively isolates the night vision green / blue-white light and the night vision red light source.

[0041] After the handle seat is pulled up, the nine optical fibers installed in the optical fiber limit seat gradually move away from the upper surface of the optical fiber limit seat, and the brightness of the light cover gradually decreases until the handle seat is pulled up and in place, the optical fiber is farthest from the optical fiber limit seat, and the brightness of the light cover is the lowest at this time. However, since the operator is manipulating the handle seat by hand, the light column and the light cover are blocked by the hand at this time, and the reduced brightness will not affect the pilot and other personnel. When the handle seat is released, as the pressure of the compression spring is released, the handle seat returns to its original position, and the optical fiber also returns to its relative position with the optical fiber limit seat, and the brightness remains the same as the initial state.

[0042] The above only expresses the implementation mode of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
