Description
Technical field
The utility model belongs to unmanned helicopter technical field, concretely relates to a kind of unmanned helicopter tail boom connection
Device.
Background technology
Tail boom is used for single rotor form helicopter fuselage back segment with tail-rotor, and end is equipped with empennage, tail-rotor and tailskid, existing
The tail boom majority of some unmanned helicopters is provided with two oblique pulls for increasing the stability of tail boom, and the setting of oblique pull causes machine
Body structure extension is limited.
The content of the invention
The purpose of this utility model is to provide a kind of unmanned helicopter tail boom attachment device, and tail boom is not made in needs
It just can reach the strength and stability of requirement with oblique pull, simplify housing construction, the possibility of enhancing housing construction extension.
In order to solve the above technical problems, what the purpose of this utility model was realized in：
A kind of unmanned helicopter tail boom attachment device, including tail boom seat and clamping portion, it is characterised in that：The tail boom seat with
Clamping portion is connected, and there are two halfpipe housing, two housings mutually fasten and are bolted to form a full circle clamping portion tool
Passage is for double team in tail boom.
On the basis of said program and as the preferred embodiment of said program：One end of the clamping portion is provided with fixation
Seat, the semi-circular protruding portion that fixed seat is circumferentially extended respectively by the same side of two halfpipe housings encloses, on tail boom seat
The groove with the fixed seat clearance fit is provided with, which is coaxial arrangement with fixed seat, clamping portion, then by fixed seat
Being caught in groove can easily be positioned.
On the basis of said program and as the preferred embodiment of said program：The fixed seat is evenly equipped with spiral shell with tail boom seat
Fixed seat and tail boom seat are connected by keyhole, bolt hole for bolt.
On the basis of said program and as the preferred embodiment of said program：The tail boom seat upper surface and bottom surface are set
There is the threaded hole being connected with rack.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：Clamping portion is set using Hafu-type structure
It puts, i.e., tool mutually fastens there are two halfpipe housing, two housings and is bolted to form a full circle passage for sandwiching
On tail boom, two semicanals of such structure are actually also nearly only complete semicircle, right when complete split
Tail boom side generates very big extruding force, can clamp tail boom, but tail boom will not be pressed from both sides and deformed again, and connection is reliable；In addition root
Increase the length of clamping portion according to the length of tail boom, improve the stability of tail boom.
