The invention discloses a flying dust prevention foot pad which comprises a hollow rubber pad, an elastic metal net and a braided fabric dust filtering ring, the braided fabric dust filtering ring wraps the peripheral side of the elastic metal net, the elastic metal net is arranged in the hollow rubber pad and fills an inner cavity of the hollow rubber pad, and a dust collection groove array is arranged on the upper surface of the hollow rubber pad. Dust collection holes are formed in the bottoms of dust collection grooves, the dust collection holes are communicated with an inner cavity of the hollow rubber pad, a first disc-shaped rubber sheet is arranged at the lower end of each dust collection hole, and the first disc-shaped rubber sheets are in point connection with the interior of the hollow rubber pad; a pressure relief hole is formed in the annular side of the hollow rubber pad, a second disc-shaped rubber sheet is arranged at an outlet of the pressure relief hole, and the second disc-shaped rubber sheet is connected with an external point of the hollow rubber pad. By means of the internal and external pressure difference generated by deformation of the rubber pad, when the rubber pad is treaded, dust left on the surface of the foot pad is sucked and stored in the foot pad, and flying dust is reduced.

    本发明公开了一种防飞尘脚垫,包括中空橡胶垫、弹性金属网和编织物滤尘环,所述编织物滤尘环包裹于弹性金属网周侧,所述弹性金属网设置于中空橡胶垫内部且充满中空橡胶垫的内部空腔,所述中空橡胶垫上表面设置有集尘槽阵列,所述集尘槽底部设置有吸尘孔,所述吸尘孔连通中空橡胶垫的内部空腔,所述吸尘孔下端设置有第一碟型胶片,所述第一碟型胶片与中空橡胶垫的内部点连接;所述中空橡胶垫环侧设置有泄压孔,所述泄压孔出口设置有第二碟型胶片,所述第二碟型胶片与中空胶垫的外部点连接。本发明利用胶垫被踩踏时发生形变产生的内外压差,将滞留在脚垫表面的灰尘吸入存储于脚垫内部,减少飞尘。
