In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a dustproof sealing ring, includes the sealing washer body, one side of the sealing washer body is equipped with the rubber outer lane, one side of rubber outer lane is equipped with the oil gallery, the top of rubber outer lane is equipped with single lip circle, the inboard of the sealing washer body is equipped with dustproof blade, the bottom of the sealing washer body is equipped with the draw-in groove, the bottom of draw-in groove is equipped with double lip circle, one side of the sealing washer body is equipped with the seal groove, the inside of seal groove is equipped with O type circle.

Preferably, the top of the sealing ring body is fixedly provided with a rubber outer ring, and an oil return hole is fixedly formed in one side surface of the rubber outer ring.

Preferably, a single lip ring is fixedly arranged at the top of the rubber outer ring, and a dustproof cutting edge is fixedly arranged on the inner side surface of the sealing ring body.

Preferably, a clamping groove is fixedly formed in the bottom surface of the sealing ring body, and a double-lip ring is fixedly connected to the bottom of the clamping groove.

Preferably, a sealing groove is fixedly formed in one side surface of the sealing ring body, and an O-shaped ring is embedded and connected in the sealing groove.

Compared with the prior art, the utility model has the beneficial effects that:

1. Through seal groove and O type circle that is equipped with, improved the abrasionproof nature in the external side of sealing washer, O type circle has fabulous regulation and locate capability in the inside of seal groove, further prolonged the life of sealing washer body.

2. Through the single lip circle and the double lip circle that are equipped with, can improve the holistic leakproofness of sealing washer body, inwards have the scraping oil function of U-shaped sealing washer to and outwards have the scraping dustproof effect that prevents the invasion of filth, can prevent simultaneously that remaining oil film from extending on the piston rod.
