Description

Portable fully sealing electrode holder

The utility model relates to the electrode holders that a kind of electric welder uses, promptly a kind of totally-enclosed electrode holders.

The insulating barrier at positions such as the pincers handle of existing electrode holders, pressure handle, binding clip adopts 4～6 screws to fix, screw cap is exposed outside, the situation of perspiring and being shocked by electricity owing to hand during welding until the moist normal generation of gloves, the hand-holding part of soldering turret in use becomes flexible or loses owing to screw, cause insulation sleeve and binding clip to break away from or rotation, the soldering turret insulating reliability reduces; Simultaneously because terminals are the connecting modes that compress cable by screw, sometimes point of attachment produces virtual connection, local electrical resistance increases, make pincers scalding one's hand, No. 85204252 patent has increased a collet between electric conductor and handle, make the heat of electric conductor and welding cable directly not reach handle, but this has just temporarily reduced the handle surfaces temperature.The structure of existing electrode holders makes that soldering turret itself is heavier, and the external force that presses the soldering turret needs is bigger.

The purpose of this utility model is to overcome the many disadvantages that above-mentioned electrode holders exist, design a kind of light, non-scald on hand, safe and reliable, clamping is firm and the totally-enclosed electrode holders in labour-saving.

Design feature of the present utility model is: in be placed in the insulation crust of retaining part opening, in the interior cover end being arranged is the core bar of clamping head, make clamping head and interior cover form variable grasping part, the other end of core bar links to each other with binding post, core bar is with spring and follow-up nut successively by the first end of clamping outward, the follow-up nut the support protrusion position with by the handle be connected, by press the boss of follow-up nut by handle, make spring along continuous straight runs under the effect of follow-up nut flexible, play clamping action.

The utility model is described further in conjunction with embodiment below by accompanying drawing.

Fig. 1 is a whole cutaway view of the present utility model

Fig. 2 is the vertical view of the utility model clamping head

Fig. 3 is by cam is pitched schematic diagram

Fig. 4 be along C to cam fork bottom plan view

Referring to Fig. 1, interior cover (7) places insulation crust (1), have corresponding mouthful at the clamping head position of shell, so that welding rod is by the clamping head clamping in the interior cover, cover top portion and side have louvre (9), be equipped with core bar (2) in the interior cover (7), one end of core bar (2) is being fixed and its all-in-one-piece clamping head (13), clamping head (13) can form variable grasping part with interior cover, the core bar other end binding post (12) of ining succession, binding post and core bar be with clench nail (11) riveted joint, virtual connection occurs when avoiding work, and the electrode holder heating is scalded one's hand.Core bar is with spring (8) by the first end of clamping outward, follow-up nut (10) near spring housing, in put at clamping head and telescopic spring position and have mouth; The clamping head external diameter is greater than the core bar diameter, and the external diameter that is enclosed within the core bar upper spring makes spring withstand on the convex edge of clamping head end less than the clamping head external diameter like this.On the follow-up nut (10) a support protrusion position is arranged, be the cam-shaped twin props, see Fig. 3, Fig. 4, by (a 5) crust is insulating barrier, by fixing in the handle by cam being pitched (15), by being cam fork bottom one arc fork, in the middle of the cam twin props that the cam fork is clipped on the follow-up nut,, axle (4) it is connected with the cam hole that cam is stuck by being passed twin props.Cover withstood on the outer follow-up nut of core bar in jackscrew (6) passed, and, had both played the effect that the follow-up nut is connected with the inner sleeve, cover rotation in preventing again with 90 ° of angles keeping follow-up nut and clamping head point-blank.Brake block (3) passes core bar, and the brake block cap that is stuck on the core bar is pitched into sliding-contact with the arc bottom cam is pitched.See Fig. 2, have the holding angle (14) of different angles on the clamping head, holding angle (14) is respectively preceding 45 °, back 45 °, 90 ° angles, to satisfy the clamping welding rod in different directions and position work.The junction of insulation crust (1) is for being threaded, and insulation crust can be various insulating materials, makes as insulation duroplasts etc.

Depress earlier during work by handle, make by the arc fork of bottom on the brake block of sliding core pole, also work simultaneously with by the cam twin props on the follow-up nut that the cam fork is linked to each other, make the follow-up nut promote spring, force spring to shrink, make clamping head with in be with a welding rod grasping part, when welding rod is sandwiched in this space, extension elastic force by spring promotes clamping head and interior cover shortening space, and welding rod is tightly clamped.

These electrode holders insulation crust hand-holding part adopts with anterior insulation sleeve and is threaded, except the retaining part opening, whole soldering turret is totally enclosed type, greatly improved insulating reliability and security, be particularly suitable in the ball-type tank, be to use in the environment of electric conductor and the work high above the ground around in the pipeline etc. The utility model can substitute the soldering turret of existing 300A and two kinds of specifications of 500A, can all make standardized element and install, and rational in infrastructure simple, the required external force of clamping welding rod is littler, and soldering turret weight is about 0.5 kilogram.
