Abstract

The utility model discloses an electronic igniting cutting torch in hand-pressing type with wind-proof function. An electric spark generator which is composed of a press-button (15), a casing (16), a metallic electrode (17) and an electrode wire (7) is arranged in a handle of the cutting torch. The press-button (15) is exposed outside the handle, the shell (16) is vertically arranged in the handle, the metallic electrode (17) tightly clung to the wall of a combustible gas conveying pipe is a small copper sheet, the electrode wire (7) is arranged on the outer side of a high voltage cutting oxygen pipe (5) in parallel, and the tail section of the electrode wire (7) enters a cutting torch head (4); the electrode wire passes through a thread hole of a housing pin of the cutting torch head, and then passes through a ceramic pipe (18) to the annular space of a cutting nozzle (1).

Description

Hand-pressing wind-proof electronci ignition torch for cutting

The utility model relates to a kind of hand push type wind resistance electronic ignition cutting torch, belongs to steel heat cutting specific purpose tool.

Existing cutting torch generally is no self-ignition cutting torch, after opening the fuel gas switch during use, strike a match with hand again or other ignitor, both wasted energy, burn hand again easily or burn out ignitor, it is not only dangerous but also inconvenient to work together, in order to overcome these deficiencies, the electronic ignition cutting torch has appearred, and this electronic ignition cutting torch has overcome unsafe deficiency, but owing to itself add the annex height, complex structure increases the weight of cutting torch, uses very inconvenient, the rate of lighting of this besides electronic ignition cutting torch is low, and being not suitable for is especially having wind field ground, open-air open work and work high above the ground are used.

The purpose of this utility model provides and a kind ofly can be applicable to the use of various places, wind resistance, safety, hand push type wind resistance electronic ignition cutting torch easily, to overcome above-mentioned weak point of the prior art.

The purpose of this utility model is achieved in that the utility model comprises cutting torch, big nut, housing pin, torch head, the high pressure cutting oxygen pipe, mixture pipe, plastic bushing, cutting oxygen valve, the Low Pressure Oxygen valve, handle, the combustible gas carrier pipe, oxygen conveying pipe, cutting torch is connected with torch head by big nut, torch head and high pressure cutting oxygen pipe, mixture pipe connects, the high pressure cutting oxygen pipe is provided with cutting oxygen valve, mixture pipe is provided with the Low Pressure Oxygen valve, cutting oxygen valve communicates with the Low Pressure Oxygen valve and is connected the combustible gas carrier pipe with handle, oxygen conveying pipe is placed in parallel in the handle.The utility model is provided with the electric spark TRT, is made up of button, housing, metal electrode, electrode wires.The electric spark TRT is installed in the handle, the button of this device upper end places handle outer, the lower end is provided with metal electrode, metal electrode film is close on the combustible gas carrier wall, by drawing a strip electrode line on the electric spark TRT, the parallel outside that is placed on the high pressure cutting oxygen pipe of electrode wires, electrode wires is passed plastic bushing and is placed in the torch head, in torch head, electrode wires is passed the through wires hole of torch head housing pin, penetrates then in the annular space that earthenware is incorporated into cutting torch and mouth core.

The purpose of this utility model can also reach by following measure: be provided with cutting nozzle core in the cutting torch of the present utility model, cutting nozzle core is provided with various through wires holes.

Embodiment describes the utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an electric spark generating device structure schematic diagram of the present utility model.

Fig. 3 is the utility model torch head and cutting torch syndeton schematic diagram.

Fig. 4 is the profile of the utility model along cutting nozzle core A--A direction in the big nut.

The long 30mm of electric spark TRT of the present utility model (11), wide 5mm weighs 10 grams.With handle apart from (9) 2 centimeters places of cutting oxygen valve, open the square hole of a 5mm, electric spark TRT (11) is bumped in the handle, combustible gas carrier pipe (14), it is curved that oxygen conveying pipe (13) is pressed with little spill, the housing (16) of electric spark TRT (11) is positioned at combustible gas carrier pipe (14), in the middle of the spill of oxygen conveying pipe (13) is curved, housing (16) is plastic products, the top of housing (16) is the button (15) of electric spark TRT, the 7mm height of button (15) is exposed at the outside of handle (12), the metal electrode of electric spark TRT (17) is a circular copper sheet, copper sheet is close on the combustible gas carrier wall, draw an electrode wires (7) by another of electric spark TRT on extremely, parallel high pressure cutting oxygen pipe (5) outside that is placed on of electrode wires (7), and be inserted in the plastic tube simultaneously with cutting oxygen pipe, pass cutting oxygen valve (9), plastic bushing (8) enters in the torch head (4), have through wires hole on the housing pin (3) in the torch head, electrode wires (7) is passed earthenware (18) after entering through wires hole, passes from an aperture of cutting nozzle core (19) then and enters into annular space (20).Have 7 apertures on the cutting nozzle core of the present utility model (19), promptly cut the oxygen through hole, gaseous mixture through hole, electrode wires through hole etc., the through-hole aperture of electrode wires is 2mm.

Working procedure of the present utility model is: open the Low Pressure Oxygen valve earlier, the back is opened flammable air valve and is pressed button (15) again, when fuel gas passes through annular gap, electric spark can puncture the fuel gas air curtain, cutting torch is lighted, electric spark is created in the inside of cutting torch (1), so wind outside does not influence finishing of igniting more greatly yet.

It is strong to the utlity model has compared to existing technology wind loading rating, and the saving energy (without battery) manufacturing process is simple, easy to use, and handling safety is lighted the rate height, is generally 100%, is desirable wind resistance electronic ignition torch.
