[0002] Grooved pipe fitting connection technology, also known as clamp connection technology, has the problem that existing pipe clamps have poor sealing performance, which can lead to water leakage at the pipe joints. They also cannot properly clamp the grooved pipe fittings, causing them to loosen and become damaged.

[0003] In the prior art, patent (CN213236427U) proposes a detachable and splicable grooved pipe fitting, including a pipe body and a clamp. Connecting rings are installed at both ends of the pipe body. The clamp can be split into two halves. Two annular grooves are provided on the inner wall of the clamp for placing the connecting rings. A ring-shaped rubber ring is installed on the rear inner wall of the annular groove. Hidden grooves are provided on the upper and lower sides of the annular groove, and springs are installed in the hidden grooves. One end of the spring is fixed to the inner wall of the hidden groove, and the other end is connected to a clamping block. Fixing ring blocks are provided on both sides of the clamp. Through holes are provided at both ends of the fixing ring blocks, and bolts penetrate the through holes. A fixing knob is fitted on one side of the bolt. Through the cooperation of the annular grooves and connecting rings, coupled with the design of the ring-shaped rubber rings, the grooved pipe fitting can be effectively connected with good sealing, preventing water leakage. The clamping block design effectively fixes the connecting rings, preventing loosening and protecting the grooved pipe fitting.
