Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As depicted in figs. 1 and 2, a kind of keyboard with automatic anti-dust device comprises keyboard body 1, one end of this keyboard body 1 is provided with dust shield case 2, the end face of this dust shield case 2 is higher than above keyboard body 1, and dust shield case 2 is provided with opening (omit in figure and do not draw) towards the side of the vertical setting of keyboard body 1; And the relative both sides of keyboard body 1 are respectively equipped with a slideway 3.
The present invention also comprises dust guard, and this dust guard comprises:
Spool 42 as shown in Figure 1, Figure 2 and Figure 3, this spool 42 is located in dust shield case 2, ensures that it can rotate during installation; Spool 42 is wound with strip for blocking the stainless steel substrates 40 above keyboard body 1, dust shield case 2 is stretched out from opening in the end of this stainless steel substrates 40, the both sides of stainless steel substrates 40 are provided with the bound edge 400 for increasing security, and namely the both sides of stainless steel substrates 40 can not hurt people; The stainless steel substrates 40 of the present embodiment is thin slice, makes it easy to retract.
