Fig. 2 is the A-A cross-sectional schematic in Fig. 1.
Fig. 3 is the part B enlarged diagram in Fig. 2.
Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
Embodiment 1
As shown in Figure 1, Figure 2 and Figure 3, a kind of aircraft of collapsible hold-down arm, it comprises the hold-down arm 2 that frame 1 and six are connected to described frame 1, six hold-down arms 2 are around described frame, angle between adjacent support arm 2 is 60 °, and namely six hold-down arm 2 uniform ring are to being distributed in frame 1 around.
One end of hold-down arm 2 is installed with hold-down arm Foldable assembly 3, and the other end of hold-down arm 2 is provided with screw propeller assembly.Screw propeller assembly comprises screw propeller (figure does not show) and drives the motor 4 of screw propeller, and screw propeller is fixed on the rotating shaft of motor 4, and motor 4 is affixed with hold-down arm 2; The axial line of the rotating shaft of motor 4 is parallel with the midperpendicalar of frame 1.
The hold-down arm Foldable assembly 3 being located at hold-down arm 2 one end is connected with frame 1 axle by rotating shaft 5.Hold-down arm Foldable assembly 3 comprises Coupling 31 and elastic rail fastening 32, and Coupling 31 is sheathed on hold-down arm 2, and be interference fit between Coupling 31 and hold-down arm 2, rotating shaft 5 is arranged in Coupling 31, and elastic rail fastening 32 is shaped in Coupling 31.Frame 1 is provided with Access Division 11, and Access Division can be fixed by screw and frame.
When elastic rail fastening 32 unclamps with Access Division 11, hold-down arm 2 can rotate around frame 1.Like this, hold-down arm is folding, when transporter aircraft, hold-down arm can be folded, thus reduces the volume of aircraft, only just need can place aircraft with less chest, has both been convenient to transport, has also been easy to carry.
When elastic rail fastening 32 and Access Division 11 clamping, hold-down arm 2 tiltedly above extends and with frame 1 in a angle, a angle is 18 °.When aircraft is for taking, frame underhung camera.Hold-down arm is tiltedly upper to be extended, and the obstacle within the scope of camera view is reduced, therefore, effectively can reduce the impact of the structure such as hold-down arm, screw propeller on shooting effect.
Elastic rail fastening and Access Division are existing common components.Preferably, elastic rail fastening 32 can be a plastic hook, and Access Division 11 can be a crampons, and this plastic hook is provided with the crook with the clamping of crampons phase.Like this, by the clamping of crampons and plastic hook, good fixed effect is reached.
For the ease of to the clamping between elastic rail fastening and Access Division and the operation of unclamping, the surface of described elastic rail fastening 32 can be provided with a button 33, and the surface of button 33 is provided with multiple anti-slip veins.
Embodiment 2
The difference of the present embodiment and embodiment 1 is only, when elastic rail fastening 32 and Access Division 11 clamping, hold-down arm 2 tiltedly above extends and with frame 1 in a angle, a angle is 8 °.
When the aircraft of the present embodiment is for taking, horn also can not cause stop to the visual field of the camera of frame underhung, thus effectively reduces the impact of the structure such as hold-down arm, screw propeller on shooting effect.
