Abstract
The utility model relates to a welding tool, specifically to a pocket welding pen, which has no drawbacks of prior electric welding devices such as unwieldy size, inconvenient operation, power dependence etc. and comprises a pen tube, which has within a cartridge full of agents, two ends of the cartridge having conical combustion-supporting masks connected; the pen tube has an igniting head at front end and a combustion-retarding head at rear end, between the igniting head and a combustion-supporting mask being an igniting section replete of igniting agents; the pen tube has protective cases at ends and a marking color band corresponding to a tail of a conical combustion-supporting mask; an igniting magnesium strip passes through front end head of the cartridge and the igniting section. Compared with existing technology, the utility model has small size and does not need a power supply; with convenient usage and simple structure, the utility model only needs a lighting source to initiate the continuous chemical reaction of the filled agents within for welding completion.
Description
Technical field
The utility model relates to a kind of soldering appliance, is specially pocket weldering pen.
Background technology
Welding equipment commonly used at present is to be the equipment of main flow with the electric welding, its volume heaviness, handle to be difficult for and to need jumbo power supply as supporting and can launch very strong ultraviolet light when using in addition, thereby when relating to small-scale local welding, will lose more than gain.
Summary of the invention
The utility model is in order to solve existing electric welding equipment volume heaviness, to handle shortcomings such as being difficult for, relying on power supply and a kind of pocket weldering pen is provided.
The utility model is to adopt following technical scheme to realize: pocket weldering pen, comprise the shaft of a writing brush, and be provided with the cartridge case that inside is full of medicine in the shaft of a writing brush, the cartridge case two ends is provided with the combustion-supporting cover of connected taper; Shaft of a writing brush front end is provided with match board head, and the rear end is provided with fire-retardant head; It between the combustion-supporting cover of match board head and taper the section of igniting that is full of detonator.Medicine in the cartridge case described in the utility model is a thermite; thermite is made up of 26.3% aluminium powder, 11.9% magnesium powder, 2.4% titanium valve, 4.8% tri-iron tetroxide, 9.5% di-iron trioxide and 45.1% dimethyl siloxane; and cartridge case is to be made by silicate, carbonate, titanium dioxide, ferromanganese and ilmenite; to guarantee that cartridge case melts and floats on the liquid iron under hot conditions; not only can play the effect of protecting liquid iron to avoid air oxidation but also can remove impurity in the fused mass simultaneously, and guarantee welding quality.The utility model adopts the principle of thermit reaction, and the thermite in the cartridge case is lighted under the effect of the match board head and the section of igniting and begun and fused solution iron generation displacement reaction, reaches the purpose of welding afterwards.After cartridge case had burnt, fire-retardant head can make flame put out, and the operator is played the certain protection effect.
The shaft of a writing brush described in the utility model termination is provided with protective sleeve, the match board head in case accident is ignited.
Be provided with sign chromatape on the shaft of a writing brush described in the utility model and corresponding to the afterbody of the combustion-supporting cover of taper, when the combustion-supporting cover of taper burnouts, can formally begin with the expression welding.
Be penetrated with the magnesium ribbon of igniting between the cartridge case front end described in the utility model and the section of igniting, the medicine in the cartridge case can be ignited after burnouting with the assurance section of igniting.
The utility model is compared with prior art, and is not only small and exquisite but also do not need to use power supply, only need burning things which may cause a fire disaster cause in the chemical reaction that continues of powder charge agent and finish welding, easy to operate, simple in structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1-shaft of a writing brush 2-cartridge case 3, fire-retardant the 7-section of igniting of the combustion-supporting cover of the 4-taper 5-match board head 6-8-protective sleeve 9-sign chromatape 10-magnesium ribbon of igniting
The specific embodiment
Pocket weldering pen comprises the shaft of a writing brush 1, and the shaft of a writing brush 1 is made for combustible materials such as paper or plastics, be provided with the cartridge case 2 that inside is full of medicine in the shaft of a writing brush 1, this medicine is a thermite, and cartridge case 2 two ends are provided with the combustion-supporting cover 3,4 of connected taper, and the material of the combustion-supporting cover of taper is a celluloid; The shaft of a writing brush 1 front end is provided with match board head 5, and match board head 5 is consistent with the employed medicine component of common match end, and the shaft of a writing brush 1 rear end is provided with fire-retardant 6, fire-retardant 6 for cement etc. not combustible material solidify and form; For being full of the section of igniting 7 of detonator, wherein detonator can be commercially available Schmidt and welds special-purpose pyrophoric powder between the combustion-supporting cover 3 of match board head 5 and taper; The shaft of a writing brush 1 termination is provided with protective sleeve 8; Be provided with sign chromatape 9 on the shaft of a writing brush 1 and corresponding to the afterbody of the combustion-supporting cover 3 of taper; Be penetrated with the magnesium ribbon 10 of igniting between cartridge case 2 front ends and the section of igniting 7.
When being used to weld; take off protective sleeve, light match board head, under the effect of ignite magnesium ribbon and the combustion-supporting cover of taper, make the thermite burning in the cartridge case then so that detonator, ignite magnesium ribbon and the combustion-supporting cover of taper burn successively; under hot conditions,, reach the purpose of welding with iron generation displacement reaction.The high temperature of its generation simultaneously can be so that outside cartridge case fusing and floating on both can have been played the protection liquid iron on the liquid iron avoid the work of air oxidation and can remove impurity in the fused mass simultaneously, and guarantee welding quality.After cartridge case had burnt, fire-retardant head can make flame put out, and the operator is played the certain protection effect.
