The invention discloses a snap ring mechanism, and belongs to the field of pipeline maintenance and plugging. The snap ring mechanism comprises a nut, a bolt, a snap ring and a limiting piece; a connecting column is arranged at the first end of the nut; a connecting groove is formed in the snap ring; the connecting column is a circular table structural piece; furthermore, at least one diagonal plane is arranged on the peripheral wall of each of the connecting column and the connecting groove; the second end of the nut is in threaded fit with the first end of the bolt; a driving convex column is coaxially arranged at the second end of the bolt; the driving convex column is rotatably inserted into the inner peripheral wall of a flange; the limiting piece is fixedly inserted into the outer peripheral wall of the flange; the driving convex column is axially clamped between the flange and the limiting piece; and a through hole is formed in the limiting piece. According to the invention, the nut is in threaded connection with the bolt; the nut is connected with the snap ring, so that the snap ring can be driven to move by driving the bolt to rotate; therefore, a plug handle and the flange are clamped; the snap ring mechanism can effectively drive the snap ring to move; and the arrangement efficiency of the snap ring is improved.
Description
technical field [0001] The invention belongs to the field of pipeline maintenance and plugging, and in particular relates to a clasp mechanism. Background technique [0002] After the damaged pipeline completes the plugging operation, it is necessary to plug the plugging tee on the damaged pipeline opening, so as to realize the sealing of the damaged pipeline opening. [0003] The main method of sealing the tee is to insert the plug handle at the flange of the tee, and push the snap ring inserted on the inner wall of the flange through the push rod, so that the snap ring snaps on the plug Handle and flange, so as to complete the plugging of the plugging tee. [0004] However, since the snap ring is an arc-shaped structural member, it is not easy for the push rod to push against and push the snap ring, which makes the above method inconvenient to operate and difficult to control the snap ring, resulting in low efficiency in the arrangement of the snap ring.
