Therefore, when in use, the polyethylene corrugated tube 21 is first hot-melted to the end of the electric fusion elbow body 1, and then the adapter tube 23 is hot-melted to the polyethylene corrugated tube 21 away from the electric fusion elbow. At one end of the head body 1, the water pipe and the expanded pipe section 232 of the transfer tube 23 are fixed by hot melting; through the provision of the polyethylene bellows 21, the bending angle and bending direction can be arbitrarily changed within a safe range to ensure that the electric fusion elbow body 1 is reliably connected to the water pipe fittings without changing the original form of the electric fusion elbow body 1; through the provision of the transfer tube 23, the inner wall of the expanded pipe section 232 is a step-shaped hole 2321, which is convenient for the electric fusion elbow body 1 to connect to a variety of water pipe fittings with different diameters, and has a wide range of applications.

[0028] Depend on Figure 1 , Figure 2 and Figure 3 As shown, an anti-skid groove 211 is provided at the position where the inner wall of the polyethylene bellows 21 contacts the electric fusion elbow body 1 to improve the anti-skid effect, thereby enhancing the stability of the fixation between the polyethylene bellows 21 and the electric fusion elbow body 1.

[0029] Depend on Figure 1 , Figure 2 and Figure 3 As shown, a positioning ring 22 is fixed at one end of the polyethylene corrugated tube 21 away from the electric fusion elbow body 1, and the adapter tube 23 is fixed on the positioning ring 22. The positioning ring 22 is a polyethylene component and is hot-melted to the end of the polyethylene corrugated tube 21 when in use. The adapter tube 23 is hot-melted to the positioning ring 22.

[0030] Depend on Figure 1 , Figure 2 and Figure 3 As shown, a positioning slot 221 is provided on the positioning ring 22 for the adapter tube 23 to be inserted into. After the adapter tube 23 is inserted into the positioning slot 221, it is hot-fused with the positioning ring 22, which has high stability and improves the reliability of the connection position between the adapter tube 23 and the positioning ring 22.

[0031] Depend on Figure 1 , Figure 2 and Figure 3 As shown, the thickness of the transfer tube 23 is equal to the width of the positioning slot 221 , which has a reliable positioning effect and improves the reliability of the connection position between the transfer tube 23 and the positioning ring 22 and the stability of the connection.

[0035] Working principle and use process of the utility model: When using the electric fusion elbow connector of the utility model, firstly heat-melt the polyethylene corrugated tube 21 at the end of the electric fusion elbow body 1, and then heat-melt the adapter tube 23 at the end of the polyethylene corrugated tube 21 away from the electric fusion elbow body 1, and the water delivery pipeline is tightly against the inner wall of the stepped hole 2321 and is heat-melted and fixed with the expanded pipe section 232 of the adapter tube 23;

[0036] After the water delivery pipe fitting and the expanded pipe section 232 are hot-melted, if the water delivery pipe fitting is thin, a gap will be generated between the water delivery pipe fitting and the second straight pipe section 233. A rubber sealing ring 24 of suitable thickness is selected and bonded to the inner wall of the second straight pipe section 233 to fill the gap between the water delivery pipe fitting and the second straight pipe section 233 and improve stability and sealing performance.

[0037] The utility model can change the bending angle and bending direction at will within a safe range by setting the polyethylene corrugated tube 21, so as to ensure that the main body 1 of the electric fusion elbow is reliably connected with the water pipe fittings without changing the original shape of the main body 1 of the electric fusion elbow;
