Testing device for rubber water stop joint

The invention discloses a testing device for a rubber water stop joint, and relates to the technical field of rubber water stop joints. The detection efficiency is improved. The device specifically comprises a base, a supporting part and a testing part used for conducting pressure testing on a water stop connector body, the testing part comprises a support fixed to the outer wall of the top of the base, a piston cylinder is fixed to the outer wall of the top of the support, and a filling pipe and an adjusting pipe are welded to the outer wall of the circumference of the piston cylinder; and the piston plate is movably connected to the circumferential inner wall of the piston cylinder. The bending seat can be driven to rotate by arranging the driving plate, so that the top of the water stop joint main body can be twisted by utilizing the rotation of the bending seat, the anti-twisting performance of the bending seat can be tested, and meanwhile, the circular motion of the driving plate can be converted into th
