Description

Starter for helicopter model

Technical Field

The utility model relates to the technical field of engines, in particular to a starter for a helicopter model.

Background

The engine must be rotated by external force before operating under its own power. The process of the engine transitioning from a static state to self-running by means of external force is called starting of the engine. The common starting modes of the engine comprise a manual starting mode, an auxiliary gasoline engine starting mode and an electric starting mode, the engine is used as an engine of a flight model, and because the power is low, the mode of rope pulling or hand cranking with high labor intensity can be adopted during starting, but the engine needs to be started by using an electric auxiliary starter facing a helicopter model with slightly high required power.

The operating principle of the starter of the present helicopter model is that, the starter is held by hand, corresponding starting position in the model is inserted with the starting rod, open the inside small-sized motor of starter, the engine in the model is transmitted for through the starting rod will rotating, thereby start the engine, but in the start-up process, the starting rod must be anticlockwise rotation, in case the rotation direction changes the mistake and will damage the engine, and present starter is external power supply, connect the positive negative pole of wrong motor very easily, cause to turn to the phenomenon of makeing mistakes, the starter generally is held by one hand simultaneously, heavy motor, have very big burden, very easily can the mistake touch button switch under the pressure of one hand, the incident takes place.
