Description

Heating tube

Technical Field

The utility model relates to a heating equipment, especially a heating tube.

Background

The heating tube is formed by filling heating wires into seamless metal tubes (carbon steel tubes, titanium tubes, stainless steel tubes and copper tubes), filling magnesium oxide powder with good thermal conductivity and insulativity into the gaps, and then shrinking the tubes, and then processing the tubes into various shapes required by users. It has simple structure, high heat efficiency, high mechanical strength and excellent adaptability to harsh environment. The heating wire is drawn out from the metal tube and connected in external plug, the end of the metal tube needs to be provided with a connector for drawing out, the connector of the cover is connected with the external plug through a wire, the interfaces of the heating tube are more, the electric leakage risk is greater, the production process is complex, and the production cost is high.

Disclosure of Invention

The technical problem that this practicality will be solved provides a heating tube, reduces and connects, simplifies production technology, reduction in production cost.

In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a heating tube, includes the tubular metal resonator and establishes the heater in the tubular metal resonator, the both ends of heater are drawn forth and are connected with external plug from the both ends of tubular metal resonator respectively, the heater draws forth the outside part parcel protective sheath of tubular metal resonator, be equipped with the wire that is used for the heater between short circuit external plug and the tubular metal resonator in the protective sheath. The utility model discloses the principle: the heating wire in the metal tube is directly led out and connected with the external plug, so that the original joint at the end part of the metal tube can be eliminated, the joints are reduced, the production process is simplified, and the production cost is reduced; the heating wire outside the metal tube is short-circuited through the metal wire, after the external plug is electrified, current is directly transmitted to the heating wire inside the metal tube through the metal guide wire, the led heating wire does not work to generate heat, and the whole heating tube is safe and reliable.

As an improvement, the protective sleeve is a transparent rubber sleeve.

As an improvement, a heat-shrinkable sleeve is arranged at the joint of the protective sleeve and the metal pipe.

As an improvement, the metal pipe is an aluminum alloy pipe or a copper pipe, and the metal wire is a copper wire.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 3, a heating tube includes a metal tube 1, a heating wire disposed in the metal tube 1, and an external plug 3 disposed outside the metal tube 1. The metal pipe 1 is an aluminum alloy pipe or a copper pipe, and can be bent and shaped according to different requirements. Two ends of the heating wire are respectively led out from two ends of the metal tube 1 by 10-30 mm and then connected with the external plug 3; the heating wire section 6 outside the heating wire leading-out metal tube 1 wraps the protective sleeve 2, and the protective sleeve 2 is a transparent rubber tube sleeve and has good insulating and waterproof properties; a heat-shrinkable sleeve 4 is arranged at the joint of the protective sleeve 2 and the metal tube 1, and sealant can be filled into the end part of the metal tube 1, so that water vapor enters the metal tube 1 from the joint; be equipped with in the protective sheath 2 and be used for short circuit external plug 3 and tubular metal resonator 1 between the wire 5 of heater section 6, wire 5 is the copper line, wire 5's one end and external plug 3's contact electric connection, wire 5's the other end along heater section 6 entering tubular metal resonator 1.

The utility model discloses the principle: the heating wire in the metal tube is directly led out and connected with the external plug, so that the original joint at the end part of the metal tube can be eliminated, the joints are reduced, the production process is simplified, and the production cost is reduced; the heating wire outside the metal tube is short-circuited through the metal wire, after the external plug is electrified, the current is directly transmitted to the heating wire inside the metal tube through the metal guide wire, the led heating wire does not work to generate heat, and the whole heating tube is safe and reliable.
