Abstract

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

A kind of jockey for helicopter model tail undercarriage
Technical field
The present invention relates to a kind of jockey for helicopter model tail undercarriage.
Background technology
