20.0mm Square Nut For Unmanned Aerial Vehicles Locking Positioning Pins

Tethered drones, infrared night vision cameras, high-definition pan-tilt, loudspeakers, throwers, emergency communication modules, lighting equipment.

Security for large-scale events, forest fire prevention, flood control and disaster relief, earthquake rescue, search and rescue for missing persons, emergency networking communication.

• Wide high-altitude vision, large monitoring range, real-time image transmission
• Infrared imaging penetrates smoke and darkness for rapid target positioning
• Tethered drones enable 24-hour hovering duty
• Capable of delivering first-aid kits, drinking water and life-saving equipment
• Designed for reliability with wind resistance, rainproofing and crashworthiness

Improve public security and emergency response capabilities, reduce casualties.

• Non-standard fixed bracket for thrower: Secures the throwing device, with rotatable structure for angle adjustment and high load-bearing capacity.
• Non-standard adapter for loudspeaker/lighting equipment: Connects equipment and fuselage, waterproof and wind-resistant without affecting sound or lighting output.
• Non-standard fixed buckle for tethered cable: Fixes the tethered cable, anti-slip and wear-resistant, capable of withstanding cable tension (usually ≥50kg).
• Non-standard crash protection strip for fuselage: Protects fuselage and payload, impact-resistant and wear-resistant, suitable for complex emergency environments.

1. Material priority: Stainless steel (corrosion-resistant, impact-resistant) or engineering plastic with metal inserts; protection strips can use metal wrapped in rubber for enhanced crashworthiness.
2. Load-bearing requirement: Thrower bracket must withstand more than 3 times the weight of thrown objects (usually 1-5kg) to avoid fracture during deployment.
3. Protection level: Adapters and buckles must reach IP67 or higher to withstand heavy rain, heavy smoke and other emergency conditions, with waterproof, dustproof and anti-corrosion properties.
4. Adaptability: Choose rotatable brackets according to throwing angles (0-90°); cable buckles shall fit cable diameters (usually 10-20mm) and allow quick disassembly.
