Embodiment
Below in conjunction with drawings and Examples, that the utility model is described in further detail is as follows:
As Figure 1-4, described light path switching device, can be switched in light path B by the light in wherein light path A, namely light can at two free switching directions of light path.
Described light path switching device basic functional principle is as follows:
Motor 0714 can in certain angular range reciprocating rotary, by the transmission of large pinion wheel 0716,0718, drive swing arm 0703 respective range swing, therefore, the position and the reflecting face that are fixed on the catoptron 0705 in swing arm 0703 change.Before required angle is put in swing arm 0703, the plectrum 0707 be fixed in swing arm touches limit switch 0708, and motor 0714 stops driving.When required angle is put in swing arm 0703, attracted each other by the limited block 0702 in frame and the magnet 0711 in swing arm, kept relative position motionless.
Described light path switching device comprise frame 0701, catoptron 0705, catoptron trim ring 0710, mirror unit 0704, swing arm 0703, rotating shaft 0719, flat key 0715,0717, gear wheel 0718, pinion wheel 0716, bearing 0713, motor 0714, limited block 0702, spacing magnet 0711, magnet frame 0712, plectrum 0707, limit switch 0708, socket 0709, balancing weight 0706.
