Abstract
The utility model relates to a pair of electric welding pliers with a holding handle with heat protection and creepage protection, belonging to the improvement of a tool of the electric welding pliers for holding electric welding rods. Because the electric welding pliers utilize a release spring and a V-shaped spring to fix exterior trimming and insulating parts, no screws for fixing the exterior trimming and insulating parts are arranged on the integral electric welding pliers, and aspects of creepage protection and insulating performance are further reliable. The double-layer holding handle adopts a gear-shaped sectional plane for connection and a suspension type heat-insulated method of a middle annular shape, which is obviously superior than the existing electric welding pliers. Labor conditions are improved, and work efficiency is enhanced.
Description
The utility model relates to a kind of handicraft arc-welding instrument, particularly a kind of transformation of clipping alternating current-direct current manual metal-arc welding electrode holders.Existing various electrode holders, because due to its structure, make the hold-down screw of electrode holders expose outside at electrode holders exterior trim insulating part, hold-down screw pincers heart body direct again and the electrode holders conduction links, so fixing screw is also charged, though the handle of electrode holders also is double-deck, when linking, the end is semiclosed, can better not dispel the heat, heat-blocking action.Therefore, the effect of ventilation and heat is not good enough, in the operation and easily and metal bump, causes short circuit and damages electrode holders, also damages electric welding machine when serious.Above-mentioned problem such as all brings many inconveniences for operative employee author, has also shortened the working life of electrode holders.
The utility model is to adopt following proposal to realize, to have the electrode holders return spring now uses, return spring withstands on the little bowl, little bowl is pressed on the nut, connect the jackscrew that penetrates conduction pincers heart body by nut, clamp in the heart body process when interior handle is inserted in conduction, interior handle jackscrew upwards pushes back a spring, interior handle is inserted in the back return spring back-pressure that puts in place, and jackscrew is pressed on the interior circular arc type hole of interior handle.
Electrode holders jaw sheath is that cover is inserted on the pincers heart body of conduction, is the screw that need not leak electricity, and the jaw sheath is provided with a V-type spring between the conduction pincers heart body, and the slotting good back of cover just tightens automatically.
With these the two kinds fixing methods of exterior trim insulation, major advantage is a screw of having cancelled the band electric leakage, long-time use the part that is coupled to each other loosening, do not come off.
The electrode holders handle is divided into interior handle, outer handle, overlapping gear type cross section, two ends Zhi Chao behind the outer handle sleeve of interior handle, making inside and outside handle all is a contact, the heat of handle just can not import outer handle into like this, simultaneously for better heat insulation, the unsettled air draught of utilizing of mid portion ring-type overlapping behind interior handle, the outer handle sleeve is dispelled the heat, and uses all non-scald on hand for a long time.Linking between the inside and outside handle is provided with the V-type spring and tightens automatically, is not screwed too.
Below in conjunction with accompanying drawing the present invention is described in further detail, the mark in the accompanying drawing is: 1, handle 2, air vent 3, V-type spring 4, outer handle block card 5, electricity pincers heart body 6, nut 7, little bowl 8, jackscrew 9, locking card 10, return spring 11, last handle 12, fan type ox horn support 13, V-type spring 14, jaw sheath 15, outer handle 16, outer handle block 17, outer handle A-A18, louvre 19, gear type cross section 20, outer handle B-B21, ring-type unsettled 23, interior handle circular hole 24, the fan type ox horn support 25 of handle circular hole part in being inserted in, rubber sleeve 26, circle Lantern hole 27, be inserted in jaw jacket portions fan type ox horn support 28, top, convex hole 29, convex hole 30, conduction pincers heart body worker type cross section
Referring to figure: return spring (10) is pressed in little bowl (7) nut (6) and penetrates conduction pincers heart bodies (5) and will push to jackscrew (8) when interior handle is inserted in the conduction pincers heart body process, return spring (10) is under pressure, what package passes through fan type ox horn support (12) bounce-back bearing down on one silk (8) on return spring (10) and the conduction pincers heart bodies (5), jackscrew (8) and being clamped in the circular arc aperture in the interior handle (1).Jaw sheath (14) is inserted in conduction pincers heart bodies (5) by convex hole (29) location on the jaw sheath, this localization method, top, convex hole (28) stenosis is blocked conduction pincers heart body worker type cross section (30), also increased the thickness of jaw sheath (14) wall when can not swing, improved service life, be exactly that jaw sheath (14) front is by arclight, the convex hole still can be enclosed within on the conduction pincers heart body firmly when electric spark burnt out, do not come off and still can use normally, for making jaw sheath (14) better fixing, be inserted on the conduction pincers heart body fan type ox horn supports (27) in jaw sheath circle Lantern hole (26), again by jaw sheath V-type spring (13) chucking.
Outer handle (15) sleeve is fixed two inside and outside handles by V-type spring (3) chucking on interior handle (1).During outer handle (15) sleeve, when the outer handle of control can not axial rotation in the ditch of handle grooved in outer handle block card (4) inserted, also be stuck on the V-type spring (3).Interior handle gear type cross section (19) outer handle (15) together all is the contact of point, the heat of interior handle (1) can not import outer handle (15), for better heat insulation, overlapping mid portion behind interior handle, the outer handle sleeve, ring-type unsettled (21), such structure is by test aborning, when 100 ℃ above freezing of interior handle, just about 20 ℃ above freezing of outer handles also are with the rubber sleeve (25) that arc protection light and electric spark scald one's hand on the interior handle (1).
