Abstract

Disclosed is a pair of heat isolating electric welding tongs, which belongs to a pair of electric welding tongs which is suitable for alternating current and direct current manual arc welding, providing a pair of novel heat isolating electric welding tongs, which can prevent cables swing because a handle of a pair of electric welding tongs is hot to ensure electric welders can work normally. The utility model is characterized in that a jaw is connected with a casing tube which is arranged in a handle and is used for passing through the cables and screws used for pressing a sheath tube; the end part of the bakelite handle is provided with a hanging ring. The utility model has the advantages of simple structure, easy fabrication and low manufacturing cost.

Description

Heat isolating electrode holder

The utility model genus is applicable to alternating current-direct current manual metal-arc welding electrode holders.

At present the electrode holders cable that generally uses is that endoporus by bakelite handle links to each other with associated jaw portion, uses screw fastening again.Because the effect of expanding with heat and contract with cold of jaw in use, the swing of cable is rocked when operating in addition, cable and jaw joint are loosening easily, this place's resistance increases, easier to be loosening when particularly carrying out vertical position welding or overhead welding operation, produce a large amount of heats, cause the heating of electrode holders handle, influence electric welder's normal operation.

At the problems referred to above, the purpose of this utility model is to provide a kind of improved electrode holders, can prevent because of the heating of electrode holders handle, prevents disorderly swing of cable, to guarantee the novel solar heat protection electrode holders of electric welder's operate as normal.

The utility model is finished with following mode: it has the tong-like structure that associated jaw portion and vice body partly constitute; Constitute associated jaw portion by upper jaw 9 and 4 connections of lower jaw 6 usefulness pins, upper jaw 9 outer surfaces have upper jaw guard shield 8, and have louvre 15, and lower jaw 6 outer surfaces have lower jaw guard shield 5, and the pincers place of chewing is connected with copper plate 7; Vice body partly is following structure: lower jaw 6 is connected with sleeve 2 and also is connected with bakelite handle 1, and sleeve 2 outer surfaces are fixed with sheath with sunk screw 3; Upper jaw 9 is connected with handle, be fixed with sheath 10 on its outer surface, and and sleeve 2 between be connected with tension spring 12, be with ebonite bush 11 outward, feature is to be equipped with to be used to wear the sleeve pipe 13 that passes through cable in the handle that upper jaw 9 is connected with, and is useful on the screw that compresses sheath 10 and fastening sleeve pipe 13; Hang circle 14 in addition in bakelite handle 1 end.

The utility model is owing to changed the mode that common electrical soldering turret cable links to each other with jaw by bakelite handle, can eliminate the blank area that links to each other with jaw because of cable and cause bakelite handle heating phenomenon because of loosening heating, simultaneously because cable has certain bending length in soldering turret, and cable can be compressed, significantly reduced the loosening phenomenon of cable adapter and taken place.Simple in structure, easy to manufacture, its version and existing electrode holders are similar, and the part parts can be general.Low cost of manufacture.

Now in conjunction with the accompanying drawings the utility model is described in further detail

Fig. 1 is the utility model structural representation

With reference to Fig. 1, the utility model is to make improvements on the basis of existing electrode holders, and cable enters in the hole of upper jaw 9 and fixes with headless screw through hanging circle 14, sleeve pipe 13.The effect of hanging circle 14 is to prevent disorderly swing of cable, prevents that electrode holders centre-of gravity shift from influencing work.Sleeve pipe 13 can impact with thin-walled welding pipe making or sheet iron to be made.Upper jaw 9 usefulness are cast red copper or are made with thin sheet copper punching press, and bore louvre 15 in the above.Sleeve pipe 13 is fixed with upper jaw 9 usefulness sunk screws.Sheath 10 is the bakelite insulation, and fixing with sleeve pipe 13 and upper jaw 9 by screw, the while screw works to compress cable.Tension spring 12 is installed in the ebonite bush 11, keeps electrode holders that enough chucking power clamping welding rods are arranged, be welded with the thick copper plate of 2mm 7 on the lower jaw 6, lower jaw 6 is welded on the sleeve 2 again, and sleeve 2 is the thin skin welded tube.Sleeve 2 usefulness sunk screws and bakelite handle 1 are fixing.

Claims

1, a kind of solar heat protection electrode holders have the tong-like structure that associated jaw portion and vice body partly constitute; Connect the formation associated jaw portion by upper jaw [9] and lower jaw [6] with pin [4], upper jaw [9] outer surface has upper jaw guard shield [8], and has louvre [15], and lower jaw [6] outer surface has lower jaw guard shield [5], and the pincers place of chewing is connected with copper plate [7]; Vice body partly is following structure: lower jaw [6] is connected with sleeve [2] and also is connected with bakelite handle [1], and sleeve [2] outer surface is fixed with sheath with sunk screw [3]; Upper jaw [9] is connected with handle, is fixed with sheath [10] on its outer surface, and and sleeve [2] between be connected with tension spring [12], be with ebonite bush [11] outward, it is characterized in that:

In the handle that upper jaw [9] is connected with, be equipped with and be used to wear the sleeve pipe [13] that passes through cable, and be useful on the screw that compresses sheath [10] and fastening sleeve pipe [13]; Hang circle [14] in addition in bakelite handle [1] end.
