Abstract:
A dustproof device is provided for use with a ball screw which includes a screw rod and a nut mounted around the screw rod. The dustproof device includes an annular body and an elastic valve plate. The annular body is disposed inside the nut and penetrated by the screw rod and has an outer annular surface provided with a debris exit. The debris exit has one end in communication with a spiral passage formed between the screw rod and the nut. The elastic valve plate, which is provided at the opposite end of the debris exit of the annular body, can be pushed open by a fluid and thus opens the debris exit, allowing the debris generated by the ball screw to be discharged through the debris exit along with the fluid, thereby contributing to extending the service life of the ball screw.

Claim (Index 6):
The dustproof device of  claim 4 , wherein the pore has a cross-shaped cross-section.
