Abstract

The utility model relates to a pen iron, which is an electric iron which can hold soldering tin. The pen iron is mainly composed of a copper body 6, lining aluminium 5, a piston plate 11, a tin-holding cavity 10 and resistance wires 7. The utility model replaces a traditional electric iron which affixes tin once after soldering once, and the pen iron can solder a lot of timesas long as tin is fed once. The utility model is more suitable for continuously wireless electric soldering, frequent continuous soldering and quick soldering.

Description

Pen iron

Pen iron is a kind of electric iron that can accommodate scolding tin.

Present electric iron can only be got scolding tin and welds object with the flatiron head end is sticking, during welding, often needs stickingly on the scolding tin to get scolding tin, picks up also inconvenience of scolding tin, brings a lot of troubles to the worker.

The purpose of this utility model provides a kind of electric iron that can accommodate scolding tin, just can weld a lot of objects as long as add a tin in holding the tin chamber, has realized needn't be often gluing to the scolding tin getting scolding tin and welding object.

Accompanying drawing is a cross-sectional view of the present utility model, and each label is respectively among the figure: 1-guide rod hole, 2-heat-insulating shield, 3-spring, 4-handle, 5-lining aluminium, 6-copper body, 7-resistance wire, 8-flatiron end, 9-Xi Men, 10-appearance tin chamber, 11-piston plate, 12-add tin dismounting screw thread, 13-piston plate guide rod, 14-spring chamber, 15-spring blocking plate, 16-piston plate button.

This utility model serves as a contrast aluminium mainly by the copper body, and piston plate holds the tin chamber, Resistance wire 7 forms. The copper body is the circle copper with inner chamber, and lining aluminium is a circle Aluminum barrel, the spring chamber is One metal cylinder, piston plate are plate piston. Copper body 6 is around with resistance wire 7, the copper body Be lined with aluminium 5 in 6, in the lining aluminium 5 cavity 10 arranged, lining aluminium tip is Xi Men, Holding in the tin chamber 10 has several piston plates 11, and piston plate is fixed on the guide rod 13, Piston plate and the chamber hermetic seal of appearance tin, and can in holding the tin chamber, be free to slide the spring chamber 14 with serving as a contrast aluminium 5 by being screwed at, and spring blocking plate 15 is solid with guide rod 13 Fix on together, the spring 3 natural jack-up spring blocking plates 15 in the spring chamber, the other end is blocked The lining aluminium an end on, heat-insulating shield be fixed on again be beneficial on the spring chamber 14 alleviate hot, Handle 4 is fixed on again on the heat-insulating shield 2 so that hand is taken, and installs one on the piston guide rod 13 Individual button is so that manual control.

Its operation principle of accompanying drawings.Back out the spring chamber by screw thread 12 and make spring chamber and lining aluminium be divided into two bodies, in holding the tin chamber, attach block tin, screw on then, connect power supply and make resistance wire 7 heatings, the block tin in the tin chamber is held in fusion, and this moment, Pen iron will keep flat, treat that block tin merges into an organic whole and can operate that during welding, the hand handle of putting on airs presses the button 16, tin liquor just flows on the parts from tin door 9, unnecessary tin liquor needs only release button, and tin liquor just is drawn into holds in the tin chamber unnecessary cool in this way block tin, want with the flatiron end it to be melted earlier, again release button.Using lining aluminium 5 is because aluminium is difficult for combining with tin, is difficult for oxidation again, and the lining aluminium wall of solder tip is thin especially, so that the Xi Men place many aluminium of copper are few, not sticking tin in the chamber, and soldering iron tip is the good result of sticking tin.

When welding object at every turn, all to arrive by traditional electric iron the sticking scolding tin of getting on the scolding tin, the utility model just can weld a lot of objects as long as add a tin, needn't be often stickingly to the scolding tin get scolding tin and weld object, it is more useful in wireless continuous welding and other frequent continuous welding, the satisfactory hand of answering, speed is fast, has brought a lot of convenience to the worker.

Embodiment: with the 50W electric iron is example, lining aluminium chamber directly is 6mm, wall thickness 2mm, the lining aluminium endoporus of soldering iron tip is that 1mm is thick, and wall thickness is 0.2mm only, this some very crucial, the copper body diameter is 20mm, solder tip copper body diameter 4mm will make three piston plates freely seal slip in holding the tin chamber, and these critical components are just done and are over.

Claims

Pen iron is a kind of electric iron that can accommodate scolding tin, feature of the present utility model is: it is by lining aluminium 5, lining aluminium 5 has one to hold tin chamber 10, hold in the tin chamber piston plate 11 that can be free to slide is within it arranged, piston plate is fixed on the guide rod 13, an end of 13 has button 16, lining aluminium 5 is tightened against one with the spring chamber by screw thread, spring 3 is arranged in the spring chamber, nature lower spring 3 is spring blocking plate 15 jack-up, and heat-insulating shield 2 is fixed on the spring chamber, and handle 4 is fixed on the heat-insulating shield, copper body 6 lock rings are in lining aluminium outside, but the external resistance wire 7 that is wound with electric heating of copper.
