Abstract
The utility model discloses a remote control airplane with a propeller protection function, which comprises a motor, a propeller, and a fairing; a motor output shaft is disposed on the motor; the fairing is mounted at the front end of the propeller; the airplane is characterized in that a protection device is disposed between the propeller and the motor output shaft; the protection device comprises two connectors and a rubber ring; the two connectors are respectively connected with the motor output shaft and the propeller; the rubber ring is connected with the two connectors. One of the connectors is provided with a shaft hole fitting with the motor output shaft; the motor output shaft is located in the shaft hole; the other connector is provided with a shaft fitting with the propeller, and the shaft is located in a shaft hole on the propeller. According to the utility model, when the propeller is subject striking, the angle between the propeller and the output shaft can be changed, and the impact force is separated, which protects the propeller and the output shaft from damage; the utility model can also maintain the aesthetic property of the front side of the propellel.
Description
Technical field
The utility model relates to a kind of telecontrolled aircraft, specifically a kind of telecontrolled aircraft with screw propeller defencive function, good looking appearance.
Background technology
Now on the market telecontrolled aircraft screw propeller mainly adopts two kinds of fixed forms: a kind of is directly to be fixed on the motor drive shaft (or output shaft) shortcoming of this mode: output shaft is easy to bending when clashing into when screw propeller receives, and screw propeller breaks easily; Another kind is screw propeller to be hung on the accessory on the output shaft shortcoming of this mode with rubber ring: rubber ring directly hangs on the screw propeller very not attractive in appearance.
Summary of the invention
The purpose of the utility model provides a kind of telecontrolled aircraft with screw propeller defencive function, good looking appearance.
The purpose of the utility model realizes through following technical scheme.
A kind of telecontrolled aircraft with screw propeller defencive function; Comprise motor, screw propeller and fairing, motor is provided with motor output shaft, and fairing is installed in the front end of screw propeller; It is characterized in that: be provided with fender guard between said screw propeller and the motor output shaft; Fender guard comprises two adaptor unions and rubber ring, and two adaptor unions are connected with motor output shaft, screw propeller respectively, and rubber ring connects two adaptor unions.
Said wherein a connector is provided with the axis hole that matches with motor output shaft, and motor output shaft is positioned at axis hole, and another adaptor union is provided with the axle that matches with screw propeller, and this is positioned at the axis hole on the screw propeller.
The utility model compared with prior art has the following advantages.
The utility model receives when clashing at screw propeller, and screw propeller can change angle with output shaft, and impulsive force is separated, thereby protects screw propeller and output shaft not to be damaged; The utility model can also keep screw propeller fwd aesthetic property.
Description of drawings
Fig. 1 is the structural representation that the utlity model has the telecontrolled aircraft of screw propeller defencive function.
The specific embodiment
Below in conjunction with accompanying drawing the telecontrolled aircraft that the utlity model has the screw propeller defencive function is described in further detail.
As shown in Figure 1; The telecontrolled aircraft that the utlity model has the screw propeller defencive function comprises motor 1, screw propeller 2 and fairing 3, and motor is provided with motor output shaft, and fairing is installed in the front end of screw propeller; Be provided with fender guard between screw propeller and the motor output shaft; Fender guard comprises that two adaptor unions 4 are connected with motor output shaft, screw propeller respectively with rubber ring 5, two adaptor unions, and rubber ring connects two adaptor unions.Wherein a connector is provided with the axis hole that matches with motor output shaft, and motor output shaft is positioned at axis hole, and another adaptor union is provided with the axle that matches with screw propeller, and this is positioned at the axis hole on the screw propeller.
When screw propeller receives external impacts, separate between two adaptor unions, impulsive force just can not be delivered on the output shaft like this; Thereby protect the output shaft can be not impaired; And screw propeller is also because the separation of protector, the disappearance at this point of resistance, thus just well protected screw propeller can not damage.
