Embodiment Construction
[0015] Such as Figure 1 ~ Figure 3 As shown, the UAV landing gear retractable locking mechanism provided in this embodiment includes a cylinder 4, a piston rod 6 slidably arranged in the cylinder 4, and a power assembly that drives the movement of the piston rod 6. The piston rod 6 A through hole is opened along its axis, one end of the piston rod 6 passes through the cylinder 4 and a guide sleeve 5 is arranged between the cylinder 4, and a rod head 7 for connecting other components is fixed in the through hole at the end of the piston rod 6, The other end of the piston rod 6 is formed with a sliding sleeve 61 that slides with the inner wall of the cylinder barrel 4. The outer diameter of the sliding sleeve 61 is 1.5 to 2.5 times, preferably 2 times, the outer diameter of the piston rod 6. The inner diameter of the sliding sleeve 61 is The diameter of the through hole of the piston rod 6 is 1.5 to 2.5 times, preferably 2 times, so as to ensure a higher connection support stre...
