Description

The igniter of welding torch or cutting torch

The utility model relates to the igniter of welding torch or cutting torch, particularly welding torch or cutting torch.

In welding procedure, the utilization of gas welding, gas cutting is very universal.But present employed welding torch, cutting torch all must be lighted a fire with match or lighter.One must carry match or lighter in addition like this; Its two, ignition operation needs two hands to cooperate, and holds welding torch or cutting torch for one, the another hand should be twisted the gentle oxygen valve of acetylene air valve, strikes a match again or makes the combustion lighter, and is very inconvenient, sometimes even need the another one people to assist just can finish ignition operation; Its three, during with the igniting of match or lighter, careless slightly meeting is sprayed onto on that hand of igniting the acetylene torch of lighting and burns, and is very dangerous.

The purpose of this utility model provides and a kind ofly can make welding torch and the cutting torch ignition operation is safer, welding torch and cutting torch igniter more easily.

For achieving the above object, the main technical schemes of the igniter of the utility model welding torch or cutting torch is: a telescoping mechanism of using " U " shape anchor ear to fix is being arranged on the mixing tube of welding torch or on the cutting torch of cutting torch.Between one end of the front arm of this telescoping mechanism and the front end of substrate, between the other end of front arm and the place, semi-girder centre position and between the rear end of an end of rear arm and substrate, all adopt turning cylinder to flexibly connect between the other end of rear arm and the boom point.The two ends of compression spring device withstand on respectively on the dead axle of the turning cylinder at semi-girder centre position place and the rear arm other end.Sparking mechanism in the useful bolting of front end of semi-girder.

The emery wheel of this lighter hinge on grinding carriage connects, emery wheel can freely rotate on grinding carriage, the front end of foot piece is with the screw thread that the screwed hole of attacking with grinding carriage lower end axial direction adapts, in axial direction about 2 centimetres of dark apertures are arranged the place, axle center at foot piece, firestone and flint compression spring are arranged in this aperture.The end of foot piece becomes 90 ° to be bent to form one and to stir handle.

According to this programme, as long as the emery wheel of igniter is pressed against on the surface of other planar objects, promptly promote forward, emery wheel rotates the friction firestone just strong spark can take place, and lights acetylene gas, need not other burning things which may cause a fire disaster, ignition operation safety, convenience.In addition,, foot piece and grinding carriage be threaded, so change, additional firestone is all very convenient because adopting.

Below in conjunction with accompanying drawing 1, Fig. 2, Fig. 3 and Fig. 4 the utility model embodiment is described.

Igniter shown in Figure 1 is to be fixed on by two holes 33 (seeing Figure 11) on the igniter substrate 3 on the mixing tube 1 of welding torch with " U " shape anchor ear 2.One end 22 of the front arm 12 of igniter (is seen Fig. 2, when mentioning each concrete position of parts of telescoping mechanism to descend to the mortal world, even see Fig. 2) and the front end 15 of substrate 3 between, between the other end 21 of front arm 12 and the meta position 14 of semi-girder 6, and between the rear end 16 of an end 17 of rear arm 4 and substrate 3, all adopt turning cylinder to be connected between the other end 18 of rear arm 4 and the end 19 of semi-girder 6, the two ends recess 29 and 30 (seeing Figure 12) of compression spring device 5 withstands on respectively on the dead axle 13 of semi-girder 6 centre positions, 14 turning cylinders and postbrachium 4 other ends 18, on the front end 20 of the semi-girder 6 of telescoping mechanism, useful bolt 8 is by the fixing sparking mechanism of hole 26 (see figure 3)s on the foot piece 9, the emery wheel 11 of this sparking mechanism hinge on grinding carriage 10 connects, emery wheel 11 can freely rotate on grinding carriage 10, the front end of foot piece 9 is with screw thread, the rear end becomes 90 ° of bendings, form one and stir handle 7, there is a screwed hole 27 at place, axle center, grinding carriage 10 lower end, foot piece 9 front ends are threaded by hole 27 with grinding carriage 10, in axial direction there is hole 25 dark about 2 centimetres at place, foot piece 9 front end axle center, there are firestone 23, flint compression spring 24 in the inside.Under the effect of flint compression spring 24, firestone 23 is pressed on the surface of emery wheel 11 like this.

Compression spring device 5 shown in Figure 12 is by the sealing of one thick one a thin end, and

band depression

30 and 29 circular sleeve 32 with 31 pairs of covers and become, compression spring 28 is enclosed in the inside, then can freely stretch when two ends are stressed.

During ignition operation, the pushing fixed handle 7 forward, when shifting certain stroke onto, under 5 effects of compression spring device, " " one, telescoping mechanism can stretch out automatically, make the sparking mechanism reach predetermined ignition location, as shown in Figure 1, suitably open acetylene air valve and oxygen valve, then emery wheel 11 slightly firmly is pressed against on the more flat object surfaces, promptly push away forward, emery wheel 11 rotates friction firestone 23 and sends strong spark, lights inflammable gas acetylene.

After igniting finishes, pull back and stir handle 7, when moving certain stroke to, under the effect of compression spring device 5, " " telescoping mechanism can automatic drawing back, make sparking mechanism get back to initial position, as shown in Figure 4, finish ignition operation, use very convenient.

Igniter of the present utility model is installed in the embodiment on the cutting torch, on the cutting torch that is installed in cutting torch, its technical scheme is identical.Therefore, its explanation and schematic diagram all omit.

Certainly, igniter of the present utility model not only can be installed on the welding torch or cutting torch of burning acetylene gas, but also can be installed on welding torches or cutting torch of other combustion matter, as with gasoline being the welding torch or the cutting torch of combustion matter, and on the igniting apparatus of other easy combustion gas, liquid.
