[0011] As a further solution of the utility model, the packing washer matches the buckle, and both the packing washer and the buckle are made of plastic PE material.

[0012] As a further solution of the utility model, a gap is left between the buckle and the rear end surface of the elbow joint body after assembly, and the gap is 2 mm.

[0013] As a further solution of the utility model, the protective sleeve structure includes a polyurethane insulation layer and a waterproof and corrosion-resistant layer. The polyurethane insulation layer is arranged on the outer wall of the elbow joint body, and the waterproof and corrosion-resistant layer is arranged outside the polyurethane insulation layer.

[0014] The beneficial effects of the utility model are as follows: the sealing performance is improved by arranging a sealing component to prevent water leakage when the water pressure is too high; the installation of water pipes is facilitated by arranging a buckle; and a protective sleeve structure with a polyurethane insulation layer and a waterproof and corrosion-resistant layer is arranged on the outer wall of the elbow joint body, thereby greatly improving the waterproof, corrosion-resistant and thermal insulation properties of the elbow joint body, thereby improving the water supply quality and the service life of the elbow joint body.
