[0002] Electric fusion fittings are plastic (polyethylene) pipe fittings that can be melted by the temperature generated by electric current to achieve connection. Since the main material of electric fusion fittings is polyethylene, which has excellent corrosion resistance, electric fusion fittings have a relatively long service life and are suitable for connecting various water supply pipes, including building water supply and drinking water.

[0003] Patent number CN203836468U discloses an electric fusion pipe fitting comprising a hollow pipe body, a plurality of terminal ends provided on the pipe body, a plurality of terminal posts, and a plurality of resistance wires. The terminal posts are provided within the terminal ends and include a projecting end and a mounting end connected to each other. The mounting end has an open opening at the bottom thereof, and a straight hole extending axially along the terminal post at the bottom thereof. The hole has a diameter smaller than the outer diameter of the resistance wire. One end of the resistance wire is interference-fitted with the hole. The upper portion of the mounting end is provided with a plurality of anti-pullout protrusions. The electric fusion pipe fitting of the utility model improves the contact rate and connection tightness between the resistance wire and the terminal posts in the electric fusion pipe fitting, effectively avoiding the problem of contact failure between the resistance wire and the terminal posts due to loose connection, improving the electrical performance of the electric fusion pipe fitting, and ensuring the safety of the electric fusion pipe fitting.

[0004] Although the above technology improves the contact rate and connection tightness between the resistance wire and the terminal in the electric fusion pipe fitting, and effectively avoids the problem of contact failure between the resistance wire and the terminal due to loose connection, the traditional electric fusion pipe fitting is prone to rust when encountering humid air during placement, and poor contact occurs when connected to the electric fusion equipment. Therefore, a high-strength and convenient electric fusion pipe fitting is needed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a high-strength and convenient electric fusion pipe fitting, so as to solve the defect that the connecting column of the traditional electric fusion pipe fitting is easily rusted when encountering humid air during placement.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a high-strength and convenient electric fusion pipe fitting, comprising an electric fusion pipe fitting and an installation groove provided therein; a reinforcement structure is provided inside the electric fusion pipe fitting, a mounting head is installed at the top end of the electric fusion pipe fitting, a connecting column is installed inside the mounting head, and a rust-proof structure is provided on the outside of the mounting head;

[0007] The anti-rust structure includes an anti-rust cover, a fixing box, a through hole and a drying block. The anti-rust cover is installed on the top of the mounting head, and the fixing box is fixed on the top of the interior of the anti-rust cover.

[0008] A drying block is installed inside the fixing box, and a through hole is opened at the bottom end of the fixing box.

[0009] Preferably, the through holes are provided in a plurality of groups, and the plurality of groups of through holes are distributed in a ring shape at the bottom end of the fixing box.

[0014] Preferably, one end of the connecting column is connected to one end of the heating wire, and two groups of the connecting columns are symmetrically distributed on the top end of the electric fusion pipe.

[0015] The utility model provides a high-strength and convenient electric fusion pipe fitting, which has the following advantages:

[0016] By providing a reinforcement structure, when the electric fusion pipe fitting is used, the strength of the interior of the electric fusion pipe fitting can be reinforced through the coordinated use of the first reinforcement layer and the second reinforcement layer, so that the electric fusion pipe fitting is not easily bent or deformed due to external forces during use, thereby improving the overall strength of the electric fusion pipe fitting. The use of the protective layer can protect the surface of the electric fusion pipe fitting so that its surface will not be scratched during use, thereby completing the protection work.

Figure 1-Figure 5 As shown, it includes an electric fusion pipe fitting 1 and a mounting groove 2 opened inside the electric fusion pipe fitting 1; a reinforcing structure 3 is provided inside the electric fusion pipe fitting 1, a mounting head 4 is installed at the top of the electric fusion pipe fitting 1, a connecting column 7 is installed inside the mounting head 4, and an anti-rust structure 5 is provided on the outside of the mounting head 4.

[0026] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the reinforcement structure 3 includes a first reinforcement layer 301, a second reinforcement 302 and a protective layer 303. The first reinforcement layer 301 is installed inside the electric fusion pipe fitting 1, the second reinforcement 302 is installed on one side of the first reinforcement layer 301, and the protective layer 303 is installed on the outside of the electric fusion pipe fitting 1. The first reinforcement layer 301 is made of steel frame, the second reinforcement 302 is made of glass fiber, and the protective layer 303 is made of rubber. One end of the connecting column 7 is connected to one end of the heating wire 6, and the two groups of connecting columns 7 are symmetrically distributed at the top of the electric fusion pipe fitting 1.

[0027] Specifically, when the electrofusion pipe fitting 1 is used, the first reinforcement layer 301 and the second reinforcement layer 302 are used in conjunction to strengthen the internal strength of the electrofusion pipe fitting 1, so that the electrofusion pipe fitting 1 is not easily bent or deformed due to external forces during use, thereby completing the reinforcement work. The use of the protective layer 303 can protect the surface of the electrofusion pipe fitting 1 so that it will not be scratched during use, thereby completing the protection work.

[0028] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the rust-proof structure 5 includes an anti-rust cover 501, a fixing box 502, a through hole 503 and a drying block 504. The anti-rust cover 501 is installed on the top of the mounting head 4. The fixing box 502 is fixed to the top of the inside of the anti-rust cover 501. The drying block 504 is installed inside the fixing box 502. The bottom end of the fixing box 502 is provided with a through hole 503. There are multiple groups of through holes 503.

The anti-rust cover 501 and the mounting head 4 are threadedly connected.

[0029] Specifically, when it is necessary to use the electric fusion pipe fitting 1 to connect the pipeline, the pipeline is inserted into the interior of the installation groove 2, and then the anti-rust cover 501 is opened, and the electric fusion equipment is brought into contact with the connecting column 7, thereby heating the heating wire 6, melting the interior of the electric fusion pipe fitting 1, and allowing the melted raw material to fill the connection between the installation groove 2 and the connecting column 7 to complete the connection work, making it more convenient when connecting. Before the electric fusion pipe fitting 1 is used, the anti-rust cover 501 is installed on the outside of the installation head 4. After the installation is completed, the use of the drying block 504 can absorb the moisture in the air inside the anti-rust cover 501, so that the inside of the anti-rust cover 501 remains dry, so that the electric fusion pipe fitting 1 will not rust when encountering humid air, thereby completing the rust prevention work.
