Abstract
This utility model discloses a pipe plug type connector, relating to the field of connector technology. Its key technical features include a pipe, a connector inside the pipe, a screw inserted into the pipe and connector, a connecting cylinder screwed onto the screw, and a connecting seat fixedly connected to the bottom of the connecting cylinder. The connector includes a plastic tube inserted inside the pipe, a plug integrally formed at one end of the plastic tube, and four spring pieces integrally formed at the other end of the plastic tube. Limiting blocks are fixedly connected to the outside of the spring pieces. The technical effect is that the elastic deformation of the plastic tube absorbs the radial pressure when the screw is tightened, preventing the pipe from denting due to local stress concentration, thus improving the compressive strength of the pipe. The plug at one end of the plastic tube directly seals the pipe port, replacing the traditional split plug, reducing assembly steps and improving tightness. The height of the connecting seat can be adjusted by rotating the connecting cylinder, effectively leveling each moving wheel.
