Abstract
An electric heating pipe comprises an internal heating element and an external quartz tube. Wherein, both ends of the electric heating pipe are arranged with metal contacts and connected with at least one joint of an insulating pipe. The insulating pipe joint is ceramic and composed of a sleeve with two parallel sides and a central connecting strip. In addition, both ends of the electric heating pipe are sheathed respectively from one side. However, metal contacts at both ends of the electric heating pipe are exposed on the other side of the pipe joint. Moreover, the insulating pipe joint can be an integrated block. Both sides of the pipe joint are provided with holes for sheathing and fixing the pipe. Metal contacts at both ends of the pipe joint are exposed towards the other side of the pipe joint. The pipe is provided with a U-shaped, circular, butterfly or other irregular structure and is characterized in simple structure, easy operation, high reliability, increased connecting strength of the pipe joint and long service life, thus ensuring operating distance between both pipe ends and improving operating safety.
Description
Technical field
The utility model relates to a kind of electric heating tube, the electric heating tube that uses in especially a kind of warmer belongs to a kind of electrical heating element.
Background technology
In daily life, the use of electric heating element is quite universal, modal is electrothermal wire heating's element, it is after energising, and because of the resistance of resistance wire is bigger, institute is so that electric energy is converted to heat energy, thereby heating, but the heating efficiency of heating wire is lower, and is existing at present by other electric heating element, as the development trend of products such as quartz ampoule, Electric radiant Heating Film replacement.What application was more in warmer is exothermal infrared bulb, by the outside radiations heat energy of this bulb.Also have a kind of electric heating tube product to come out at present, it regains quartz ampoule by built-in heater element and outsourcing forms, and the two ends of its pipe respectively are provided with hard contact to connect power supply, and promptly it can make heat-generating pipe generation heat, and externally carries out the radiation etc. of heat.But this electric heating tube, the two ends of its pipe are not fixedly coupled device, thereby the intensity that not only connects behind the power supply is lower, is damaged easily, and connect difficult the fixing in position of power supply, have influence on the normal use of whole electric heating tube.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple in structure, easy to use, safe and reliable electric heating tube.This electric heating tube is made up of the body that built-in heater element and outsourcing regain quartz ampoule, and the two ends of body are provided with metal contact, and described body both ends are socketed at least one insulated tube joint.
Described insulated tube joint is a porcelain connector, and it is made of in flakes sleeve pipe and centre that both sides be arranged in parallel at least, and be inserted among sleeve pipe from a side respectively at the body both ends, and the metal contact at body two ends is then outer to be exposed on the opposite side of pipe joint.
Described insulated tube joint also can be the blocks that is made into integration, and its both sides are provided with for body both ends and are inserted in and the fixing sleeve joint hole of usefulness from a side, and the hard contact at body two ends is then outer to be exposed on the opposite side of pipe joint.
Described tubular form is that U type, circular ring type, buttferfly-type or other are irregularly shaped.
The utility model belongs to a kind of improvement to prior art, and it has simple in structure, and is easy to use, reliable, increased the bonding strength of body power connection, prolong useful life, can also guarantee the service range of two pipe ends of body simultaneously, improved the characteristics of using such as fail safe.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing, the utility model is made up of the body 3 that built-in heater element 1 and outsourcing regain quartz ampoule 2, the two ends of body 3 are provided with metal contact 4, be used to connect external power, it can connect on special and the matching used plug special of socket.Described body 3 both ends are socketed at least one insulated tube joint 5.This insulated tube joint 5 can be a kind of plug special structure.
Insulated tube joint shown in the figure is a porcelain connector, and sleeve pipe 6 that it is be arranged in parallel by both sides at least and centre 7 are formed in flakes, and be inserted among sleeve pipe 6 from a side respectively at body 3 both ends, and the metal contact 4 at body 3 two ends then is exposed at outward on the opposite side of pipe joint 5.
The blocks that other embodiment of the present utility model also can be designed to described insulated tube joint 5 to be made into integration, its both sides are provided with for body both ends and are inserted in and the fixing sleeve joint hole of usefulness from a side, and the hard contact at body two ends is then outer to be exposed on the opposite side of pipe joint.
Tubular form described in the utility model can be irregularly shaped for U type, circular ring type, buttferfly-type or other.
