The specific embodiment
As shown in Figure 1, 2, a kind of safe heat insulation electric welding tongs, comprise jaw 1, grip 2, main spring 13 and pressure handle 3, jaw 1 is fixed on the top of grip 2, and main spring 13 two ends are individually fixed on pressure handle 3 and grip 2 interior (above structure is electrode holders structure common in prior art);
Jaw 1 bottom has electric conductor, and electric conductor stretches in grip 2, has fixed head 9 and connecting rod 5 in grip 2;
Electric conductor is divided into electric conductor epimere 10, electric conductor stage casing 12 and electric conductor hypomere 11, upper and lower section 10 of electric conductor, 11 is all fixed on fixed head 9, electric conductor stage casing 12 is fixed on connecting rod 5, on grip 2 lateral walls, there is bar cover 16, bar cover 16 and grip 2 internal run-throughs, stretch out outside the sidewall of grip 2 through bar cover 16 one end of connecting rod 5, bar overlaps 16 tops and has outer shoulder 17, connecting rod 5 stretches out on one end of grip 2 sidewalls and has shoulder plate 18, on connecting rod 5, cover has spring 19, spring 19 two ends to be individually fixed on shoulder plate 18 and outer shoulder 17;
Pressure handle 3 bottoms have safety push-rod 4, and safety push-rod 4 one end are fixed on pressure handle 3, and the other end of safety push-rod 4 stretches in grip 2 and through fixed head 9;
During actual use, in jaw 1, clamp welding rod, when pressure handle 3 does not stress, safety push-rod 4 does not contact with connecting rod 5, and spring 19 is held connecting rod 5 contacts respectively the two ends in electric conductor stage casing 12 with electric conductor hypomere 11 with electric conductor epimere 10; Now electric current and welding rod are connected.
When pressure handle 3 stressed, when jaw 1 opens, pressure handle 3 is close to grip 2, now safety push-rod 4 contacts with connecting rod 5, promote the deformation that connecting rod 5 overcomes spring 19, drive electric conductor stage casing 12 towards moving away from upper and lower section 10 of electric conductor, 11 direction, electric conductor stage casing 12 can not contact with upper and lower section 10 of electric conductor, 11.Now welding rod is put into jaw 1, because electric conductor stage casing is in off-state, therefore whether electric conductor hypomere 11 is switched on and electric current can not introduced on welding rod, has guaranteed operator's personal safety.
Further, be fixed with spring case cover 6 on grip 2 lateral walls, it is other that spring case cover 6 is positioned at bar cover 16, and spring case cover 6 is open surface towards the face of bar cover, in spring case cover 6, has plate 7, and the open surface of spring case cover 6 is stretched out in plate 7 one end;
In spring case cover 6, have little spring 15, the two ends of little spring 15 are fixed with the inwall of plate 7 and spring case cover 6 respectively;
On connecting rod 5 sidewalls, have socket, when safety push-rod 4 does not contact with connecting rod 5, socket is positioned at grip 2 near the position of grip 2 sidewalls; Bar cover 16 is evolution face towards the face of spring case cover 6, and safety push-rod 4 can promote connecting rod 5 stretches out outside grip 2 socket, and now plate 7 can stretch in socket.In actual use, when jaw 1 opens, operator puts into jaw 1 by welding rod, cooperation due to plate 7 and socket, jaw 1 is clamped after welding rod and can not be immediately upper and lower section 10 of electric conductor stage casing 12 and electric conductor, 11 to be communicated with, need operator that plate 7 is extracted after socket to the stage casing 12 of electric conductor and could connect electric current is introduced to welding rod, so just increased an operating procedure, further ensured safety.
Plate 7 sides have shifting block 8, have the slotted hole (not shown) that can make shifting block 8 stretch out spring housing box 6 sidewalls on spring housing box 6 sidewalls, and shifting block 8 can slide in slotted hole, near or away from connecting rod 5.The operation of person to plate 7 that arrange convenient operation of shifting block 8.
Electric conductor is preferably copper conductor.
