Description
Technical field:
The utility model relates to unmanned helicopter fields, are specifically related to a kind of unmanned helicopter of detachable tail pipe.
Background technique:
Existing unmanned helicopter is an integral structure, and tail pipe is all fixed on the machine body, and length is big, it has not been convenient to be transported
And storage.
Summary of the invention:
The technical problem to be solved by the utility model is to provide it is a kind of can convenient transportation and storage detachable tail pipe
Unmanned helicopter.
Above-mentioned purpose is achieved in that identical with existing helicopter be it also includes body, and organism bottom is fixed with
Undercarriage, engine are mounted in body, and main rotor is equipped on the output shaft of engine, power transfer is additionally provided in body
Case, the input shaft of power transfer case and the output axis connection of engine, it is characterized in that: body rear end is fixed with outer tube, housing
The axial long hole through entire outer tube is provided on pipe, i.e. the length of long hole and the length of outer tube is identical, in long hole two sides
Outer tube on it is corresponding offer several pairs of Quick clamping screws installation threaded holes, every a pair of Quick clamping screw installs spiral shell
A Quick clamping screw is designed in pit, Quick clamping screw passes through two Quick clamping screws and installs threaded hole；It is i.e. fast
Fast fastening screw is protruded into out of the Quick clamping screw of long hole side installation threaded hole, then from the Quick fastening of the long hole other side
It is stretched out in screw installation threaded hole.
The first empennage power input shaft is equipped in outer tube, the rear end of the first empennage power input shaft is connected with external splines,
The front end of first empennage power input shaft is connect with power transfer case；
The front end of tail pipe is inserted into outer tube, and the second empennage power input shaft is equipped in tail pipe, and the second empennage power is defeated
The front end for entering axis is connected with internal spline, and the second empennage power input shaft and the first empennage power input shaft are connected to one by spline
It rises, the rear end of the second empennage power input shaft and the input axis connection of tail reduction gearbox, has tail rotor on the output shaft of tail reduction gearbox；
It further include support tube, rear end and the tail pipe of support tube are bolted, and the front end of support tube and underpart are logical
Cross bolt connection.
The utility model has the advantages that: unscrew the Quick clamping screw on outer tube, tail pipe is unloaded, while by the second tail
Wing power input shaft unloads, then the front end of support tube is unloaded from body.This reduces the length of helicopter, facilitate fortune
Defeated and storage.
