Upper to have the annular gear edge being equipped with limited step, the annular keeps off edge and is resisted against limit under the action of resetting structure
On step.The limited step of setting and annular gear edge can effectively limit power button and fall off out of opening.
In the power button device of endoscope, the rigidity branch for the setting that reclines with circuit board is fixed on the inside of the shell
Fagging, the bracket one are positioned between rigid support plate and shell, and the other end of the spring is resisted against rigid support plate
On, the punched out that there is power supply source switch to pass through for the middle part of the rigid support plate.Rigid support plate is for bearing camber of spring
Generated elastic force, avoids spring from causing to damage to circuit board, can effectively improve the service life of circuit board.On circuit board
Headlamp be also set in punched out.
In the power button device of endoscope, insulating layer is equipped between the rigid support plate and circuit board.When rigid
Property support plate when being made for metal, the component that insulating layer can avoid on circuit board is contacted with rigid support plate, prevents short circuit.Absolutely
Edge layer can be made of rubber material.When rigid support plate is that nonconducting hard materials such as ceramics are made, then setting can not be had to
Insulating layer.
Compared with prior art, the power button device of this endoscope has the advantage that
Power switch and spring follow power button to act together when pressing, and the size of lower pressure can pass through the parameter of spring
It adjusts, when power switch reaches predetermined stroke, pressing action terminates, and operator cancels pressing force, and recoil of spring resets, and drives
Power button resets, and the screen resilience of spring can guarantee the return stroke of power button, and spring is mounted on power button and circuit
Between plate, space is saved, it is small in size, and also structure is simple, and it is easy to assembly.
