Ultralow tension slippage ring

The utility model discloses an ultralow tension slippage ring, the utility model discloses because be equipped with graphite in concave point or the recess, long lasting lubrication can be realized tographite. But as emollient the problem that graphite dust spills over appears easily with graphite, and the utility model discloses a setting of sealing washer can prevent the loss of graphite, can prevent also that the graphite powder from gluing the film on, be equipped with the diaphragm between tensioning piece and the lifting cambered surface. Owing to there is the setting of diaphragm, thegraphite powder can the adhesion to the diaphragm, so tensioning piece and lifting cambered surface are not direct contact is favorable to reducing friction to carry high sensitivity, protection tensioning piece and lifting face, the periodic replacement diaphragm just can be guaranteed moreover the utility model discloses a sensitivity. The utility model is used for the slippage ring. 本实用新型公开种超低张力滑差环，本实用新型由于凹点或凹槽内设有石墨，石墨能
