Abstract
The utility model relates to a pair of electric welding pliers without scalding hands. The utility model comprises a handgrip, a bending hilt, a conductive body of the welding pliers, a jaw helmet and a copper head, wherein, a spring is arranged between the bending hilt and the handgrip; the handgrip comprises a front insulated sleeve and a back insulated handgrip; the back part of the conductive body of the welding pliers is arranged in the front insulated sleeve, and the front part of the conductive body of the welding pliers is arranged in the jaw helmet; a plurality of heat radiation holes are arranged on the back insulated handgrip and the jaw helmet. Because a part of the jaw helmet is provided with the heat radiation holes, heat generated by the electric welding pliers is dissipated through the heat radiation holes on the part of the helmet and the heat radiation holes in the back insulated handgrip, and stairway type heat dissipation is formed so that the handgrip is not easily hot.
Description
The utility model relates to the soldering appliance field, particularly a kind of non scalding hand electric welding tongs having.
In electric welding field, electrode holders clamping welding rod and bearing great current make between welding rod and the welding base metal and produce electric arc, dissolve welding rod and mother metal welds, and the electrode holders handle is easy to hot.In order to solve the hot problem of handle, Chinese patent just discloses a kind of non scalding hand electric welding tongs having No. 99215730.7.It adopts to be provided with between soldering turret conductor and handle isolates external member and reaches and make the not hot purpose of handle.But these electrode holders only are provided with a louvre isolating the external member top, the soldering turret conductor with isolate external member, isolate between external member and handle and adopt ring-type contact, the heat that makes the soldering turret conductor be produced is difficult lost, handle still will generate heat.Moreover, in the jaw head-shield electrode holders heatings the most concentrated, its heat is owing to there is louvre to be difficult for scattering and disappearing.
The purpose of this utility model is: provide a kind of handle surfaces temperature rise lower electrode holders.
In order to reach the above purpose, the utility model is this realization by the following technical programs:
A kind of non scalding hand electric welding tongs having comprises handle, curved handle, soldering turret conductor, jaw head-shield, copperhead; Between curved handle and the handle spring is housed; Insulation sleeve and back insulated handle before handle comprises; In the insulation sleeve, soldering turret conductor front portion was located in the jaw head-shield before soldering turret conductor rear portion was located at; On back insulated handle and jaw head-shield, be provided with some louvres.
In the utility model, between soldering turret conductor and preceding insulation sleeve and before preferably contact between insulation sleeve and back insulated handle by point continuous.Make to reach between soldering turret conductor and preceding insulation sleeve between preceding insulation sleeve and back insulated handle all to form the gap, be beneficial to heat radiation.Preceding insulation sleeve end is provided with a notch, and the soldering turret conductor part directly contacts with air.
Advantage of the present utility model is: because jaw head-shield portion is provided with louvre, the heat that electrode holders produced scatters and disappears by the louvre of head-shield portion earlier, because between soldering turret conductor and preceding insulation sleeve and before contact by point between insulation sleeve and back insulated handle continuous, just do not scatter and disappear by cross-ventilation when the most of heat that makes the soldering turret conductor produce passes to the back insulated handle, the heat on the back insulated handle is less; Louvre in insulated handle heat radiation after the warp again forms the staged heat radiation, and handle is difficult for hot.Moreover preceding insulation sleeve end is provided with a notch, and the soldering turret conductor part is directly contacted with air, and it is faster that heat is scattered and disappeared.
Be elaborated the utility model in order more clearly to illustrate below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is insulation sleeve and a back insulated handle portion schematic diagram before the utility model.
As shown in Figure 1: insulation sleeve 1 and back insulated handle 2 before non scalding hand electric welding tongs having comprises, curved 3, soldering turret conductor 4, jaw head-shield 5, copperhead 6; Curved 3 and preceding insulation sleeve 1 between spring 7 is housed.Because electrode holders are provided with preceding insulation sleeve, back insulated handle, make to reach that the heat on the insulated handle greatly reduces behind the electrode holders.Soldering turret conductor 4 front portions are located in the jaw head-shield 5; Before being fixed in by some fulcrums, soldering turret conductor 4 rear portions in the groove of insulation sleeve 1 inboard, make it to be difficult for rocking.Be equipped with some louvres on back insulated handle 2 and the jaw head-shield 5, and formation is subjected to thermal control air cavity 9 in the jaw head-shield, is beneficial to the formation hot-air convection.Preceding insulation sleeve 1 end is provided with a notch 10, and the soldering turret conductor part directly contacts with air.Under the premise that security is guaranteed, it is faster heat to be scattered and disappeared.
In conjunction with Fig. 1, shown in Figure 2, soldering turret conductor 4 contacts continuous with 1 of preceding insulation sleeve and preceding insulation sleeve 1 with 2 of back insulated handles by point; Soldering turret conductor 4, preceding insulation sleeve 1,2 of the insulated handles in back are all gapped.Not only can reduce the heat that reaches handle portion, be beneficial to cross-ventilation simultaneously and make radiating effect better.
Claims (3)
1, a kind of non scalding hand electric welding tongs having comprises handle, curved handle, soldering turret conductor, jaw head-shield; Between curved handle and the handle spring is housed; It is characterized in that: insulation sleeve and back insulated handle before described handle comprises; In the insulation sleeve, soldering turret conductor front portion was located in the jaw head-shield before soldering turret conductor rear portion was located at; On back insulated handle and jaw head-shield, be provided with some louvres.
2, non scalding hand electric welding tongs having according to claim 1 is characterized in that: contact by point between described soldering turret conductor and preceding insulation sleeve and links to each other, and continuous between preceding insulation sleeve and back insulated handle by contacting.
3, non scalding hand electric welding tongs having according to claim 1 is characterized in that: the insulation sleeve end is provided with a notch before described, and the soldering turret conductor part directly contacts with air.
