The annular convex part has lower production difficulty, and the annular convex part can completely surround the pipeline, so that the pipeline has better leakage-proof effect.
Preferably, the cross section of the annular convex part is trapezoidal, the slope of one side of the annular convex part close to the pipe orifice is larger, and the slope of one side of the annular convex part far away from the pipe orifice is smaller, so that the resistance when the pipeline is inserted is lower, and the resistance when the pipeline slides outwards is larger, and the pipeline is better fixed in the connecting pipe.
Preferably, the pipe pad is in the shape of an incompletely closed ring, and one end of the pipe pad is provided with an uncovering part for conveniently detaching the pipe pad, so that the difficulty in detaching and installing the pipe pad is reduced.
Preferably, the large tube fixing part and the small tube fixing part are both provided with at least one injection hole for injecting the filler; the tube pad is also provided with at least one opening, and the opening of the tube pad is aligned with the injection hole. Thermoplastic or other waterproof materials can be injected through the injection holes to fill the gap between the pipeline and the pipeline connecting pipe, so that water leakage is avoided.
Preferably, the quantity of pipe pad is three, can dismantle the connection between every pipe pad, can be applicable to the butt joint of the pipeline of four kinds of sizes, can satisfy most of engineering requirements, is favorable to controlling manufacturing cost again, if the quantity of pipe pad is too much, then can greatly increased production degree of difficulty and manufacturing cost.
