Sealing joint for PVC (polyvinyl chloride) pipe

Abstract

The utility model relates to the technical field of PVC (polyvinyl chloride) pipes, and discloses a sealing joint for a PVC pipe, which comprises a sealing pipe, rotating thread bushings are sleeved at two ends of the sealing pipe, limiting annular plates are fixed on the sides, far away from each other, of the two rotating thread bushings, and circular rings are arranged on the sides, far away from each other, of the two rotating thread bushings. A limiting annular groove is formed in the side, close to the rotary threaded sleeve, of the circular ring, the limiting annular plate is arranged in the limiting annular groove and slidably connected with the circular ring, fixing plates are fixed to the outer wall of the circular ring, square plates are fixed to the sides, close to each other, of the two fixing plates, mounting grooves are formed in the two ends of each square plate, and T-shaped plates are arranged in the mounting grooves. The T-shaped plates are slidably connected with the square plate, first clamping strips are fixed to the sides, away from each other, of the two T-shaped plates, and second clamping strips matched with the first clamping strips are arranged on the sides, away from the T-shaped plates, of the first clamping strips. According to the utility model, the stability of connection with the PVC pipe can be improved, and leakage and the like can be avoided.
