Abstract

The utility model belongs to electric soldering iron in the electric appliance maintenance industry, and particularly relates to tin dripping type electric soldering iron. The tin dripping type electric soldering iron comprises a welding nozzle, an outer sleeve, a piston, a heating tube, an insulation push rod, a pin, a conducting wire, a handle, a set screw, a push rod, a conducting wire joint, a reset spring, a rear cover and a button. During welding, a solder wire penetrates into a wire feeding hole, the button is pressed down, an annular cutting edge of the piston and a cutting edge of the outer sleeve act jointly to cut off the solder wire and seal the solder wire in a tin melting cavity between the welding nozzle and the piston, the button is pressed down continuously, and a solder fluid is pushed out through a tin outlet hole in the front end of the welding nozzle. The piston can form pressure difference in the tin melting cavity during reset under the action of the reset spring, and solder can be recovered, that is, the electric soldering iron has functions of the electric soldering iron and a solder sucker. The electric soldering iron can solve the problem that rosin in the solder wire volatilizes easily in the tin dripping type electric soldering iron and can further solve the problems of small contact area of the solder wire and a welding head, low temperature increase, proneness to insufficient solder and desoldering, difficulty in control of flow direction and flow rate of solder as well as requirement for both-hand operation of a common electric soldering iron.

Description

Drip tin formula electric iron

Technical field

The invention belongs to electrical maintenance industry electric iron, be specifically related to a kind of tin formula electric iron that drips.

Technical background

Rosin high temperature is volatile, a current tin class electric iron, and the ubiquity solder stick heat time, the long rosin being wherein mixed with that makes volatilized, and affected the problem of welding effect.

There is wire feed inconvenience in existing electric iron, solder stick and soldering tip contact area little mostly, and intensification is slow, efficiency is low, easily causes the problem of rosin joint, sealing-off.

The flow direction and the flow of existing electric iron scolding tin scarcely easy to control, need bimanualness, and non-soldering tin reclaims function.

Summary of the invention

For the deficiencies in the prior art, the object of this invention is to provide a kind of tin formula electric iron that drips, can effectively address the above problem.

In order to realize above-mentioned target, the present invention is achieved by the following technical programs:

Drip tin formula electric iron by tip 1, outer sleeve 2, piston 3, heat-generating pipe 4, adiabatic push rod 5, pin 6, wire 7, handle 8, holding screw 9, push rod 10, terminal 11, back-moving spring 12, bonnet 13, button 14 forms.

Described outer sleeve 1 front end has screw thread, and the right of this screw thread has wire feed hole 15, and this pore area has cutting edge 16, and the rear end of outer sleeve 1 has circumferentially 4 uniform set screw hole 17.

The front end of described piston 3 has annular cutting edge 18.

Described push rod 10 hollows and with wire notch 20, wire notch 21, its rear end is provided with the lug 19 of fixed reset spring 12.

Piston 3 is all connected by pin 6 with push rod 10 with adiabatic push rod 5, adiabatic push rod 5, and push rod 10 is connected with button 14.

Tip 1 is connected with outer sleeve 2 by screw thread, and there is heat-generating pipe 4 in outer sleeve 2 outsides, and outer sleeve 2 is connected with handle 8 use holding screws 9.

Piston 3, adiabatic push rod 5, push rod 10 are through in outer sleeve 2, form syringe-type structure.

Usefulness of the present invention is:

Adiabatic push rod 5 separates piston 3 and push rod 10, reduces heat and uploads, and avoids handle 8 to produce high temperature, and impact is used.

In the time of welding, solder stick is penetrated to wire feed hole 15, connect knob down 14, piston annular cutting edge 18 and 16 actings in conjunction of outer sleeve cutting edge are cut off solder stick be encapsulated in the molten tin chamber between tip 1 and piston 3, continue to press the button 14 and tin soldering liquid is brought out before tip to the release of tin hole after solder stick fusing.

As mentioned above, tip 1 is interchangeable, and different tips go out tin bore dia difference.

As mentioned above, when welding, solder stick is penetrated to wire feed hole 15, i.e. the present invention has wire feed feature easily, can send into length control tin output amount by control; Cut molten method because the present invention adopts, thus solder stick can be in molten chamber long-time heating, for adding the solder stick of rosin, can not cause rosin volatilization; Solder stick is encapsulated in molten chamber, and tip and solder stick contact area are large, can make solder stick rapid melting, improves welding efficiency; Because solder stick is cut off the rear molten chamber that automatically falls into, therefore can singlehanded complete operation in the time of welding; Owing to oozing from going out tin hole after melts soldering tin, so welding quality is high, weld bond is attractive in appearance.

The present invention is syringe-type structure, and piston can form pressure reduction in molten tin chamber while reset under back-moving spring 12 effects, and for reclaiming scolding tin, i.e. the present invention has had both the function of electric iron and solder sucker.

Detailed description of the invention

When welding, solder stick is penetrated to wire feed hole 15, press the button 14, piston annular cutting edge 18 and 16 actings in conjunction of outer sleeve cutting edge are cut off solder stick be encapsulated in the molten tin chamber between tip 1 and piston 3, after solder stick fusing, continue to press the button 14 and tin soldering liquid is brought out before tip to the release of tin hole, can press the button 14 speed by control and control Solder Flowrate, release button 14 after welding, push rod 10 drives button 14 to get back to original position under the effect of back-moving spring 12.

While reclaiming scolding tin, first sky presses the button 14, and piston can form pressure reduction in molten tin chamber while reset under back-moving spring 12 effects, tin soldering liquid can be reclaimed.
