Detailed Description
In order to more clearly and completely explain the technical scheme of the utility model, the utility model is further explained with reference to the attached drawings.
Referring to fig. 1-3, the key testing device of the present invention includes a supporting portion 2, a detecting portion 3, a control portion 1 and a driving portion 4, the driving portion 4 is fixedly disposed on the supporting portion 2, the control portion 1 is electrically connected to the driving portion 4, the detecting portion 3 is fixedly disposed right below the driving portion 4, the supporting portion 2 includes an accommodating groove 22 for accommodating a keyboard, the detecting portion 3 is disposed right above the accommodating groove 22, the detecting portion 3 includes a detecting head 31 and a connecting cavity 34, the connecting cavity 34 is provided with an installing column 33, a spring 32 is sleeved outside the installing column 33, a first distance sensor 35 is disposed inside the installing column 33, the first distance sensor 35 is electrically connected to the controlling portion 1, a part of the detecting head 31 extends into the connecting cavity 34 and abuts against the spring 32, the stiffness coefficient of spring 32 is not more than the stiffness coefficient of the spring inside the detected piece, one side of supporting part 2 is equipped with second distance sensor 52, the lateral part of drive division 4 is equipped with connecting strip 5, the one end of connecting strip 5 with drive division 4 fixed connection, the other end of connecting strip 5 upwards extends, and the other end of connecting strip 5 is equipped with opening 51, works as when button testing arrangement is in shutdown state, opening 51 just in time exposes second distance sensor 52.
In this embodiment, the control portion 1 is provided with a control button 11 and a display panel 12, the control button 11 can control the motion state of the driving portion 4, so as to start detection or close detection, the detection portion 3 is provided with a first distance sensor 35 inside, which can detect the distance of the detection head 31 moving towards the inside of the connection cavity 34 after being pressed, since the stiffness coefficient of the spring is not greater than the stiffness coefficient of the spring inside the detected member (i.e. the keyboard), the distance of the detection head 31 moving towards the inside of the connection cavity 34 is always greater than the distance of the downward movement of the keys of the keyboard, before detection, the limit distance of the downward pressing of the keyboard is measured, and then the limit distance is converted into the distance value of the downward movement of the detection head 31 towards the inside of the connection cavity 34, so that a range from zero to the distance value can be preset through the control portion 1, and meanwhile, since during detection, the connecting bar 5 moves downwards along with the driving part 4, so that the opening 51 moves downwards, the connecting bar 5 covers the second distance sensor 52, and the second distance sensor 52 displays the start of detection;
