Description
Technical field
This utility model relates to a kind of fire trapping ring spot welder dedicated.
Background technology
After the rapid economic development of China and construction fever, Real estate craze, the problem such as safe and environment-friendly, the energy of exposure becomes increasingly conspicuous.Plastic conduit is used widely in all kinds of public and civil buildings, but plastic conduit tends to become the passage of fire-propagation, plastic conduit heat burns the hole formed after ruining as a chimney, flame and flue gas is made to spread along pipeline from one layer and diffuse to another layer, or spread from a room and be diffused into another room, make fire damage expand.Countries in the world fire protection organization draws consistent conclusion, and plastic conduit is the arch-criminal that fire road spreads and spreads.Fire trapping ring is to be made shell, interior filling fire-retardant expansion core by metal material, is enclosed within hard polyvinyl chloride pipeline outer wall, being fixed on floor or body of wall position, when fire occurs, core is heated and expands rapidly, extrudes UPVC pipeline, within a short period of time, blocking pipe Durchgangshohle mouth, stoped the intensity of a fire to spread along hole.
Mash welder system uses two-sided two point to cross the principle that fluid welding connects, during work, two electrode pressurization workpiece make double layer of metal form certain contact resistance under the pressure of two electrodes, and welding current forms the thermal welding of moment when an electrode flows through another electrode at 2 contact resistance points, and welding current moment flow to this electrode from another electrode along two workpiece and forms loop, and the internal structure of welded piece will not be injured.
Fire trapping ring carries out soldering sometimes, but current mash welder volume is relatively big, carries inconvenience.
Utility model content
It is little that the technical problems to be solved in the utility model is to provide a kind of volume, fire trapping ring spot welder dedicated easy to carry.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of fire trapping ring spot welder dedicated, including weldering arm, wood handle, transformator and printed circuit board, described weldering arm includes weldering arm and lower weldering arm, it is provided with electrode tip on described upper weldering arm and lower weldering arm, it is provided with connecting rod between described upper weldering arm and lower weldering arm, described upper weldering arm and lower weldering arm are all articulated and connected with connecting rod, it is provided with trigger on described lower weldering arm, described trigger is rotationally connected with lower weldering arm, described trigger end is provided with spring, described trigger and upper weldering arm are all articulated and connected with spring, described transformator and printed circuit board are respectively positioned in wood handle, described transformator and electrode tip are all electrically connected with printed circuit board, described printed circuit board is connected with switch and power line.
As preferably, described upper weldering arm is provided with thermometer, the temperature of upper weldering arm can be recognized in time.
As preferably, described lower weldering arm is provided with test pencil, can detect that lower weldering arm is the most charged.
As preferably, described upper weldering arm and lower weldering arm are all connected with electrode tip clamping, Stability Analysis of Structures, connect reliable.
As preferably, described switch is positioned at faced by wood handle surface, described switch and trigger, easy to use.
As preferably, described thermometer is embedded in weldering arm and arranges, good integrity, Stability Analysis of Structures.
As preferably, described test pencil is embedded in lower weldering arm and arranges, good integrity, Stability Analysis of Structures.
As preferably, described weldering arm is enclosed with insulation rubber sleeve, good insulation effect can be played.
The beneficial effects of the utility model are: be provided by welding arm, wood handle, transformator and printed circuit board; simple in construction; volume is little; easy to carry; and transformator and printed circuit board are respectively positioned in wood handle; it is possible not only to play good insulation effect, and transformator and printed circuit board are played a good protection.
