Abstract

The utility model relates to an installation device of electrothermal tube, it is especially suitable for assembling in the metal kettle body, has mainly solved the kettle body and has easily leaked and can not use the stove fire directly to the kettle body heat scheduling problem, including sealed fastener 11 and by outer guard ring 6, plug guide ring 8, bakelite block 12, the double-deck heat-proof device 13 that electrode double-screw bolt 9 constitutes, wherein outer guard ring 6 hugs closely the kettle body 3 so that the conduction expands the heat dissipation capacity rapidly, makes it can be applicable to the stove fire and heats, also can use the electrothermal tube to heat, sealing performance is good, is difficult for leaking, can extensively be applicable to the house, the hotel, use in the environment such as dining room.

Description

Sealing and heat-proof device that electrothermal tube is installed

The utility model belongs to the erecting device in daily living article field, particularly a kind of electrothermal tube.

At present, mostly known electrothermal tube is to utilize that rubber gasket is fixed in pottery, metal or the plastics kettle body on the electrode sleeve installing, in use there is following shortcoming in it: first, electrode is subjected to the influence of plug and easily becomes flexible leakage, the spiral of minor diameter is directly as stressed fastening spiral, frangibility on the electrode bar; The second, unavailable stove fire directly heats the kettle body.

The purpose of this utility model provides sealing and the heat-proof device that a kind of electrothermal tube is installed, and it especially is fit to be contained in the metal kettle body, both can utilize electrothermal tube to heat, and also can rely on stove fire to heat, and good insulation preformance and difficult the leakage are convenient and practical.

The purpose of this utility model is achieved in that at first, electrothermal tube adopts sealing fastening device at fit on, it is made of hollow bolt, nut, silica gel sealing ring, heavy in section bolt, nut make electrothermal tube more firm, the built-in sealing area that makes of silica gel circle is dwindled, improve sealing, the sex change that also keeps from heat has overcome the defective of easy leakage; Secondly, the external connection end of electrode then adopts the double thermal insulation device that is made of outer guard ring, plug guide collar, bakelite piece, stud electrode, wherein, outer guard ring is close to the kettle body, when heating with stove fire, can be diffused into the quick conduction of the heat that stove fire radiates on the kettle body, add the heat-blocking action of plug guide collar, make electrode do not burnt out, thereby realize can be used for the purpose of stove fire heating.

Advantage of the present utility model:

The first, the use of double thermal insulation device makes its both available stove fire heating, also available electrothermal tube heating;

The second, the use of sealing fastening device makes electrothermal tube firmer, easy to leak not, good insulation preformance;

The 3rd, electrothermal tube shell and other member all are that stainless steel material is made, and be durable in use.

Structure of the present utility model is seen accompanying drawing, and wherein Fig. 1 is the electrothermal tube sealing of installing and the partial sectional view of heat-proof device, and Fig. 2 is that the A of Fig. 1 is to partial view.

Embodiment:

Hollow bolt 3 is packed into electrothermal tube shell 1, welding is fixing, put silica gel sealing ring 4, screw nut 7 formation sealing fastening devices 11 and on kettle body 5 walls, bore two holes, the aperture is slightly larger than the external diameter of hollow bolt 3, electrothermal tube 10 is injected aperture, and put outer guard ring 6, screw nut 7 again electrothermal tube is fastened on kettle body 5 walls together with outer guard ring 6; Then put plug guide collar 8 in the guard ring 6 outside, and electricity consumption wooden unit 12 blocks it, two apertures are arranged on the bakelite piece 9, electrode 2 passes through respectively thus, precession electrode column 9, fixedly bakelite piece 12 makes it tightly block plug guide collar 8, and wherein, outer guard ring 6, plug guide collar 8, bakelite piece 12, stud electrode 9 combine and constitute double thermal insulation device 13.
