Description

Polytetrafluoroethylene sealing ring structure Technical Field The utility model relates to the technical field of sealing rings, in particular to a polytetrafluoroethylene sealing ring structure. Background The sealing ring has sealing effect, and the polytetrafluoroethylene sealing ring has the characteristics of acid resistance, alkali resistance and resistance to various organic solvents, and is almost insoluble in all solvents. When the traditional polytetrafluoroethylene sealing ring is used, a worker installs the sealing ring at a working position, so that the connecting position of two parts is sealed through the sealing ring; However, when the polytetrafluoroethylene sealing ring is used, the sealing ring is easy to rotate due to lower friction force, so that abnormal friction is generated between the sealing ring and the surface of a part in the rotating process, the self abrasion of the sealing ring is accelerated, the service life is shortened, the sealing surface of the part is scratched, and the problems of scratches, pits and damage are formed. Disclosure of utility model Aiming at the defects of the prior art, the utility model provides a polytetrafluoroethylene sealing ring structure, which solves the problems that when the polytetrafluoroethylene sealing ring is used, the sealing ring is easy to rotate due to lower friction force, so that the self abrasion of the sealing ring is accelerated, the service life is shortened, the sealing surface of a part is scratched, and scratches, pits and damages are formed. The polytetrafluoroethylene sealing ring structure comprises a sealing ring, an anti-slip mechanism is arranged outside the sealing ring, the anti-slip mechanism comprises a first annular plate, a second annular plate, a first lug and a second lug, the top of the inner wall of the sealing ring is fixedly connected with the first annular plate, the bottom of the inner wall of the sealing ring is fixedly connected with the second annular plate, one side, close to the first annular plate, of the inner wall of the sealing ring is fixedly connected with the first lug, and one side, close to the second annular plate, of the inner wall of the sealing ring is fixedly connected with the second lug. Preferably, the first groove is formed in the top of the outer wall of the sealing ring, the second groove is formed in the bottom of the outer wall of the sealing ring, and the first groove and the second groove extend to the inner wall of the sealing ring respectively. Preferably, the side surface of the sealing ring is respectively provided with a first clamping groove and a second groove, and the first clamping groove and the second groove respectively extend to the inside of the sealing ring. Preferably, the upper and lower inner walls of the first clamping groove and the second groove are respectively fixedly connected with a third bump. Preferably, the outer wall of the sealing ring is provided with an extrusion-resistant part. Advantageous effects The utility model provides a polytetrafluoroethylene sealing ring structure.
