Description
Technical field
Screw propeller quick detach oar presss from both sides, and belongs to the mounting structure for propeller technical field of small aircraft.
Background technology
In SUAV (small unmanned aerial vehicle) field, especially many rotors needs to shift place frequently in using, and opposite elongate and the screw propeller of fragility needs dismounting, independent packing.Traditional oar folder convenience is not high, dismounting trouble.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy accessibility, fast speed screw propeller erecting device.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts: screw propeller quick detach oar presss from both sides, comprise blade pedestal and blade fixture, described blade base central is provided with vertical threaded column and the direction of rotation of the thread rotary orientation of threaded column and blade, multiple counter sink is evenly equipped with along blade base central surrounding, described blade fixture is provided with the connecting portion of fastening blade, and is provided with the tapped bore matched with the threaded column of blade pedestal at blade clamp base center.
Multiple counter sinks of described blade pedestal are heavy caliber counter sink.
The connecting portion of described blade fixture is be located at the screw that the uniform multiple and holding screw of blade clamp central surrounding coordinates.
The connecting portion of described blade fixture is the stud coordinated with blade center hole being located at blade clamp central.
Described blade pedestal and blade fixture are cylindrical.
Compared to the prior art the utility model has following beneficial effect.
One, blade pedestal is fixed on motor side by countersunk head screw through counter sink, screw propeller is fixed on blade fixture by connecting portion, be connected fastening by wide-aperture threaded column between blade pedestal with blade fixture, contrary with the hand of rotation of propeller blade by arranging threaded column thread rotary orientation, utilize motor rotary torsion self-tightening, reach self-locking.So change into use blade pedestal and blade fixture as intermediate structure by traditional motor side that screw propeller is directly fastened on, achieve quick assembling and the dismounting of screw propeller and motor, easy accessibility is quick, greatly facilitates the dismounting assembling of small aircraft, particularly main flow unmanned plane screw propeller and changes.
Two, the multiple counter sinks by arranging blade pedestal are heavy caliber counter sink, and make blade pedestal connect more fastening with motor, working process blade pedestal is more stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of blade pedestal.
Fig. 2 is the first structural representation of blade fixture.
Fig. 3 is the first structural representation of blade fixture.
In figure, 1 is blade pedestal, and 2 is blade fixture, and 3 is threaded column, and 4 is counter sink, and 5 is screw, and 6 is tapped bore, and 7 is stud.
