The beneficial effects of the utility model are: the metal wire is buried in the pipe joint, the pipe processing is convenient, and the welding process is convenient, and the welding operation is convenient and fast, and the heating is uniform.

Description

A hot-melt pipe fitting connector

technical field

The utility model relates to the field of hot-melt connection of plastic pipes, in particular to a hot-melt pipe connector.

Background technique

In the prior art, the connecting pipe fittings of plastic pipes are put into the resistance wire, and an exposed joint is provided at both ends of the resistance wire, such as the hot-melt pipe connector disclosed in the utility model patent with the patent number 97218248.9, through welding machine and The two exposed joints are connected, a heating voltage is set for the resistance wire, and the current change is detected by the current detection element inside the welding machine to realize heating and welding of the pipe fittings. This method often has uneven heating, too long time, and unstable welding quality of pipe fittings, which affects product quality.

Contents of the invention

The purpose of the invention of the utility model is to provide a hot-melt pipe connector with uniform heat generation and stable welding quality.

In order to achieve the purpose of the above invention, the utility model adopts the following technical scheme: a hot-melt pipe connector, including an intubation tube and a sleeve, and a metal wire is arranged on the contact surface of the intubation tube and the sleeve tube. By embedding the metal wire in the contact part of the pipe fitting, the induction coil is placed on the wire part of the electrofusion pipe fitting, and then the pipe fitting is welded by adding induction equipment to the metal induction to generate heat, which overcomes the defect that the exposed joint must be provided in the prior art, It makes the pipe processing convenient, and at the same time facilitates the welding process, making the welding operation convenient and fast, and the heat generation is uniform.

A further improvement of the utility model lies in that the metal wire is buried on the outer surface of the intubation tube.

The further improvement of the utility model lies in that the metal wire is buried on the inner surface of the casing.

The beneficial effects of the utility model are: the metal wire is buried in the pipe joint, the pipe processing is convenient, and the welding process is convenient, and the welding operation is convenient and fast, and the heating is uniform.

Description of drawings

Detailed ways

Example 1

As shown in FIG. 1 , the hot-melt pipe connector of the present invention includes a cannula 1 and a sleeve 2 , and a metal wire 3 is buried on the outer surface of the cannula 1 when the cannula 1 is formed.

The principle of the utility model is to weld the pipe fittings by embedding metal wires in the pipe fittings and generating heat for the metal induction with an external induction device. The device and method can set the voltage or current value at will, and can set the welding time. Through the peripheral heating coil, the specified welding time is completed according to the set voltage or current value. The welding equipment can effectively block the unevenness of the heating wire and the long welding time, and improve the product quality and efficiency.

Example 2

The improvement of embodiment 2 relative to embodiment 1 is that the metal wire is buried on the inner surface of the casing 2 .
