The invention relates to a connection device for a tail rotor of a helicopter model. The connection device for the tail rotor of the helicopter model comprises a rotor main body, a rotary device is arranged at the lower end of the rotor main body, a rotary shaft is actively connected to the rotary device, the upper end of the rotary shaft is fixedly connected with the rotor main body, a connection device is sleeved outside the rotary device, a notch is formed at the opening end at the upper end of the connection device, and the connection device and the rotary device can be conveniently connected through the notch, the side wall of the connection device is fixedly connected with a connection cylinder being corresponding to the tail girder of the helicopter, the outer side wall of the connection cylinder is opened with a through hole used for fixing the tail girder in the connection cylinder through the bolt. The connection device for the tail rotor of the helicopter model has split type connection to the tail girder for preventing abrasion of the tail girder for rotary of the rotor, the later period maintenance cost can be reduced and the service life of the tail girder can be greatly prolonged.
Description
technical field [0001] The invention relates to a connection device for a tail propeller of a helicopter model. Background technique [0002] The tail propellers of ordinary helicopter models are mostly directly connected to the tail boom, which is not only troublesome to disassemble, but also easily wears out the tail boom after long-term use, resulting in damage to the entire tail boom, which leads to the scrapping of the entire model, and high maintenance and replacement costs. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the above existing problems, provide a connecting device for the tail propeller of the helicopter model, which solves the problems of troublesome removal of the tail propeller of ordinary helicopters and easy wear and tear of the tail boom. [0004] The technical solution adopted by the present invention to solve the technical problem is: a connecting device for the tail propeller ...
