Abstract
The utility model relates to a mining intrinsic safety type keyboard. The mining intrinsic safety type keyboard comprises a square shell, an operation rocking bar and a USB data interface, wherein the lower surface of the square shell is open, a keyboard body is arranged at one end of the upper surface of the square shell, a touchpad mouse is arranged at the other end of the upper surface of the square shell, the operation rocking bar is located in the middle of the upper surface of the square shell, and the USB data interface is assembled in the square shell. A cover plate which is used for sealing the lower surface of the square shell is arranged on the lower surface of the square shell. An anti-explosion base plate is arranged on the lower surface of a base plate. A sealing rubber layer is arranged between the cover plate and the anti-explosion base plate. A control circuit board is arranged in the square shell. The control circuit board is provided with a drive circuit which is electrically connected with the operation rocking bar, the keyboard body, the touchpad mouse and the USB data interface. The anti-explosion base plate can have an anti-explosion function on the keyboard; the sealing rubber layer can play a role in sealing; the drive circuit can safely and stably drive corresponding components; consequently, the mining intrinsic safety type keyboard is reasonable in structural design and capable of completely meeting safety requirements of underground use.
