Oil tube connecting and sealing structure used in oil exploitation industry

The utility model discloses an oil tube connecting and sealing mechanism used in the oil exploitation industry. The oil tube connecting and sealing mechanism used in the oil exploitation industry comprises a sealing rotary shell, a deep groove ball bearing disc, a ball bearing, an elastic bearing compression ring, a nut, a first oil tube joint and a second oil tube joint. As a ball rotates synchronously, a driven shaft reverses relative to a drive shaft under action of friction countertorque; the end faces of the first oil tube joint, the elastic bearing pressing compression ring and the second oil tube joint are provided with bearing tracks wide in margin so as to ensure the self adaptability under not high coaxiality. Silicone filler can play a good role in sealing, oil leakage is prevented, and an oil tube can freely rotate. Compared with the prior art, the oil tube connecting and sealing mechanism plays a good role in sealing butt joint of the oil tube in the oil exploitation industry, the oil tube can ro
