[0013] In daily use, this lightweight connector for low-altitude aircraft works by connecting the connector body and then rotating the handle. The rotation of the handle causes the lead screw to rotate, which in turn causes the sealing ring to slide. The sealing ring then causes the vertical rod to slide inside the vertical tube. Subsequently, the vertical rod causes the round shaft to slide inside the vertical groove. Simultaneously, the sealing ring causes the moving plate and the locking block to slide until the locking block is positioned inside the slot. This seals the connection between the fixing ring and the sealing ring, improving the tightness of the connection and reducing loosening. Attached Figure Description

A lead screw 3 is rotatably installed on the top of the fixing ring 2. The bottom of the lead screw 3 passes through the fixing ring 2 and extends to the bottom of the fixing ring 2. The fixing ring 2 and the lead screw 3 are connected by threads. A sealing ring 4 is fixedly installed on the bottom of the lead screw 3. When the lead screw 3 rotates, it will cause the sealing ring 4 to slide. The connector body 1, the fixing ring 2, and the sealing ring 4 are made of carbon fiber, which is made of carbonized fiber treated with epoxy coating and graphite pressing and weaving. It is not only high in strength but also has excellent corrosion resistance. A throttle 5 is fixedly installed on the top of the lead screw 3.

The fixing plates 6 are all provided with slots 7 inside. The slots 7 are adapted to the moving plates 8. Moving plates 8 are fixedly installed on both ends of the sealing ring 4. Plate 8 and movable plate 8 are both fixedly mounted with locking blocks 9 on their tops. When the sealing ring 4 slides, it will cause the movable plate 8 and locking blocks 9 to slide. The fixed plate 6, movable plate 8, and locking blocks 9 are made of polycarbonate, which is a high molecular polymer containing carbonate groups in its molecular chain. It has excellent impact resistance, good insulation, and anti-aging properties. A vertical tube 10 is fixedly mounted on the top of the fixed ring 2. A vertical groove 11 is opened at one end of the vertical tube 10. A round shaft 12 is movably installed inside the vertical groove 11. The inner surface of 11 and the outer surface of the round shaft 12 are both smooth. A vertical rod 13 is fixedly installed on the top of the sealing ring 4. The materials of the vertical tube 10, the round shaft 12 and the vertical rod 13 are titanium alloy, which refers to a variety of alloy metals made of titanium and other metals. It has good heat resistance and high strength. The top of the vertical rod 13 passes through the fixing ring 2 and extends into the interior of the vertical tube 10. One end of the vertical rod 13 is fixedly connected to one end of the round shaft 12. When the vertical rod 13 slides, it will drive the round shaft 12 to slide inside the vertical groove 11.

[0023] Two fixing rods 14 are fixedly mounted on the surface of the connector body 1. The fixing rods 14 are identical in size and made of aluminum alloy. Each fixing rod 14 has a slot 15 inside, and a round rod 16 is fixedly mounted inside each slot 15. Slider 17s are movably sleeved at both ends of the round rod 16. The inner surface of the slider 17 and the outer surface of the round rod 16 are smooth, allowing the slider 17 to slide more smoothly on the surface of the round rod 16 and reducing the likelihood of jamming. A buffer spring 18 is fixedly mounted between the slider 17 and the slot 15. The inner surface of the buffer spring 18 is movably connected to the outer surface of the round rod 16. When the slider 17 slides, it compresses and squeezes the buffer spring 18. A fixing block 19 is fixedly mounted at the bottom of each slider 17. When the fixing block 19 slides, it moves the slider 17 within the slot 15 and on the surface of the round rod 16. Slippage occurs, and the materials of the round rod 16, slider 17 and fixed block 19 are aluminum alloy, which is an alloy with aluminum as the base and a certain amount of other alloying elements added. It has high strength. Round tubes 20 are fixedly installed on both sides of the surface of the connector body 1. Return springs 21 located inside the round tubes 20 are fixedly installed on both sides of the surface of the connector body 1. The outer surface of the return springs 21 is movably connected to the inner surface of the round tubes 20. A protective shell 22 is fixedly installed at the bottom of the return springs 21. When sliding, the protective shells 22 will squeeze and compress the return springs 21. At the same time, the protective shells 22 can protect the connector body 1. A pressing block 23 is fixedly installed on the top of the protective shells 22. When the protective shells 22 slide, they will drive the pressing blocks 23 to slide. The materials of the protective shells 22 and the pressing blocks 23 are magnesium alloy, which is an alloy composed of magnesium as the base and other elements added. It has low density and good shock absorption performance.

[0024] Working principle: First, after the operator connects the connector body 1, they rotate the handle 5. When the handle 5 rotates, it drives the lead screw 3 to rotate. At this time, the lead screw 3 drives the sealing ring 4 to slide. Then, the sealing ring 4 drives the vertical rod 13 to slide inside the vertical tube 10. Subsequently, the vertical rod 13 drives the round shaft 12 to slide inside the vertical groove 11. At the same time, the sealing ring 4 drives the moving plate 8 and the locking block 9 to slide until the locking block 9 is placed inside the locking groove 7. The connection is then sealed by the fixing ring 2 and the sealing ring 4. Next, when the protective shell 22 is impacted, the protective shell 22 drives the pressing block 23 to slide. At this time, the outer surface of the pressing block 23 continuously presses the outer surface of the fixing block 19. Subsequently, the fixing block 19 drives the slider 17 to slide inside the strip groove 15 and on the surface of the round rod 16. Then, the slider 17 presses and compresses the buffer spring 18. At the same time, the protective shell 22 presses and compresses the return spring 21, thus buffering the impact force.
