Abstract

The utility model discloses a hand-held welding electrode holder. A cord inlet clamp [3] for a power cord is arranged on the tail end of a bending arm of a common hand-held electrode holder of the welding holder; the access of the power cord from a straight handle in a handle of the welding holder can be convered to the asscess of the power cord from the cord inlet clamp [3] for a power cord arranged on the tail end of the bending arm [1] of the welding holder; the straight handle of the welding holder avoid a heat source and the heat quantity diffused to the handle of the welding holder caused by conductive current; welders can not feel the scald of the handle of the welding handle in the long welding operation; the welding quality and the work efficiency can be increased.

Description

A kind of Electrode holder

The utility model relates to the Electrode holder that a kind of Electrode holder especially has no hot handle.

The Electrode holder of Chu Shouing is exactly this structure in the market, mainly form by handle, staight shank, staight shank case, curved boom, curved boom case, upper jaw, upper jaw case, lower jaw, lower jaw case, steady pin, spring, the upper and lower case of spring, its power line is to pass to be connected on the staight shank in the handle center hole, the heat that produces when electric current is by staight shank during welding directly is diffused on the handle, especially long-time continuous welding, temperature on the welding clamp handle is higher, it is hot that the welder feels usually, thereby influence welding quality and efficient.

The purpose of this utility model provides a kind of no hot handle Electrode holder.

The technical solution of the utility model is: the curved boom tail end in the electrode holders of being made up of handle, staight shank, staight shank case, curved boom, curved boom case, upper jaw, upper jaw case, lower jaw, lower jaw case, steady pin, spring, the upper and lower case of spring makes a power line inlet wire folder, and upper jaw, curved boom, the power line inlet wire clipping of soldering turret become same overall structure, simultaneously, for guaranteeing safety, power line inlet wire folder appearance is with the curved boom case and is linked as holistic insulating sleeve case.The upper and lower jaw case of soldering turret is fixed on the back side of upper and lower jaw by screw respectively, and curved boom case and power line inlet wire folder insulating sleeve case are fixed on the curved boom by the spring fixed screw that is screwed on the curved boom.Handle is fixed on the staight shank by fixed screw, upper jaw and lower jaw afterbody have a hinge joint hole, to form half of soldering turret and second half hinge joint of forming soldering turret by lower jaw, lower jaw case, staight shank, handle together by upper jaw, upper jaw case, curved boom, curved boom case, electric power incoming line folder and insulating sleeve case with steady pin, and the upper and lower jaw of assurance is installed between curved boom and staight shank the tight spring of holding of enough folder power is arranged and be enclosed within the upper and lower case of spring outside the spring.When needs weld, with electrode carrier between the upper and lower jaw of soldering turret, connect power supply, electric current just can be pressed from both sides through curved boom to soldering turret upper jaw and lower jaw and welding rod by the power line inlet wire, like this, staight shank in the handle because of do not have electric current by the time generation thermal source, just be not diffused into the heat on the handle yet, thereby, realize no hot handle welding.For guaranteeing that curved boom and power line inlet wire anchor clamps have excellent conducting performance and enough intensity, can make curved boom and power line inlet wire clipping the overall structure of the same with the soldering turret upper jaw (as red copper) material.To produce the eccentricity that causes because of power line gravity on the welding clamp handle in order not making, at the handle tail end garden orifice ring to be set, power line is by inserting after passing in this garden orifice ring in the power line inlet wire folder again.

The power line inlet wire presss from both sides by metal sleeve, a tension disc and is at least two line ball bolts to be formed, tension disc is in metal sleeve and be pressed on the power line that inserts in the metal sleeve, the line ball bolt passes the insulating sleeve of curved boom case tail end, and is screwed into the metal sleeve that is threaded perforation and directly is pressed on the tension disc.In order to make curved boom non-slip when pressing down, be equipped with and point several finger spill wave troughs that adapt at the insulating sleeve pressure finger section position of curved boom tail end with finger.

The utility model is compared with the Electrode holder of selling in the market, when welding, just there has not been the heat that scalds one's hand on the thermal source welding clamp handle that produces when not depositing because of electric current in the welding clamp handle by staight shank yet, especially when long-time continuous welding, the welder holds welding clamp handle and just can not feel to have scalded one's hand, thereby has improved welder's operating efficiency and welding quality.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is the longitudinal section of the utility model Electrode holder.

In profilograph shown in Figure 1, front end and soldering turret upper jaw 2 with curved boom 1 in the no hot handle electrode holders of being made up of handle 9, staight shank 11, staight shank case 12, curved boom 1, curved boom case 5, upper jaw 2, upper jaw case 13, lower jaw 14, lower jaw case 15, steady pin 16, spring 17, spring upper encloser 18, spring lower encioser 19 are made for an integral body, the tail end of curved boom 1 makes a power line inlet wire folder 3, inlet wire folder 3 is insulated sleeve 4 covers inside, and insulating sleeve 4 is linked as an integral body with curved boom case 5.Power line inlet wire folder 3 is by a

metal sleeve

6, and 7, two line ball bolts of tension disc 8 are formed.Power line is inserted in the metal sleeve 6, and the tension disc 7 in the metal sleeve 6 is pressed on the power line.Line ball bolt 8 passes the insulating sleeve 4 of curved boom case tail end and is screwed in the metal sleeve 6 that is threaded perforation and promptly directly is pressed in above the tension disc 7, and power line is pressed in the metal sleeve 6.Pressure finger position at the insulating sleeve 4 of curved boom tail end is provided with three finger spill wave troughs that adapt with finger.Establish a garden orifice ring 10 that power line is passed at the tail end of handle 9.When power supply send electricity, electric current from power line inlet wire folder 3 to curved boom 1 to soldering turret upper jaw 2, thereby realize that no hot handle welds.

Claims
