Description
Technical field
The present invention relates to a kind of scalding-resistant electric-welding pliers.
Background technology
Electrode holders are used to clamp welding rod, conduct the apparatus of welding current during welding.Matching used with arc welder, during manual electric arc welding, in order to clamping and manipulating electrode, and the hand-held insulation utensil that guarantee and welding rod are electrically connected.
At present, the mode that the scalding-resistant electric-welding pliers of prior art adopts has two kinds, and a kind of is electric conductor and handle are separated by insulating assembly in the front end of electrode holders, and another kind arranges heat dissipation channel, although the former makes the temperature of handle portion reduce, but because the metallic supports of electric conductor and handle is integral type structure, and the metallic supports of metallic supports in up knob and handle is hinged, the heat then in use electric conductor produced will be transmitted on up knob through metal hinge part, thus make up knob in use still there is the higher problem of temperature, when changing welding wire, workman cannot direct control, the operation changing welding wire just can be carried out after needing cooling, make work task efficiency lower, and safety in utilization is also relatively poor, and due to heat dissipation channel, the latter is arranged so that the structure of handle is more complicated, affect the intensity of handle, and radiating effect is poor, the heat that electric conductor produces still can be transmitted on up knob through metal hinge part, and up knob still exists the higher problem of temperature.
Summary of the invention
The present invention is directed to the lower and good scalding-resistant electric-welding pliers of safety in utilization of up knob temperature when above problem provides a kind of use.
The present invention overcomes the above problems technical scheme used: provide a kind of scalding-resistant electric-welding pliers with following structure, it comprises upper clamp nozzle, up knob, back-moving spring, body cradle, handle and electric conductor, described body cradle one end is positioned at up knob, the body cradle other end is positioned at upper clamp nozzle, described electric conductor is divided into conductive part and articulated section, described one end, articulated section is provided with heat insulation, and conducting position is connected in the top of heat insulation with heat insulation, one end, articulated section is positioned at handle and is connected with handle; The middle part of described body cradle and the middle part of articulated section hinged.
After adopting above structure, compared with prior art, the present invention due to conductive part and articulated section be split-type structural, then in use articulated section and body cradle are not charged, safety in utilization is better, the heat that conductive part produces simultaneously cannot be transmitted to articulated section under heat insulation effect, heat also just cannot be transmitted to up knob, therefore the long-time state that handle and up knob also there will not be when using high temperature (more than 40 DEG C), workman can carry out welding wire timely at any time as required and change, no longer need the cooling waiting for handle and up knob, operating efficiency is higher.Therefore the present invention has the lower and good feature of safety in utilization of up knob temperature.
As improvement, the both sides of described body cradle are provided with the first pin-joint piece, and the both sides of articulated section are provided with and the first pin-joint piece the second pin-joint piece one to one; After then this articulated structure is arranged, cable directly can be connected with conductive part through hinged place, and then reduce the raw-material use amount of conductive part, also be convenient to the punch forming of conductive part and articulated section simultaneously, enhance productivity, and then reduce production cost, significantly to reduce cost of the present invention.
As further improvement, described back-moving spring is two, and one end of back-moving spring and up knob support and close, and the other end of back-moving spring and handle or articulated section are to closing; After then arranging like this, the elastic force of single spring can be reduced, and then lower the production difficulty of spring and reduce the diameter of spring, ensure the prerequisite decline low production cost of enough elastic force, and spring also not easily occurs the situation of inefficacy in use procedure, extend the service life of spring.
As improving further again, described up knob is provided with projection, projection is provided with two counterbores, the axis of counterbore is vertical with up knob, and counterbore is positioned at the both sides of up knob, described handle or articulated section are provided with and back-moving spring spring retainer seat one to one, and one end of described back-moving spring is arranged in each self-corresponding counterbore, and the other end of back-moving spring is to being combined on each self-corresponding spring retainer seat; Then this spring is positioned at the setting of handle both sides, after cable is entered from the rear portion of handle, can directly pass between two springs, do not need again as original needs on handle to cable reserved passageway, the structure of handle is simpler, preparation cost is also just lower, and spring and handle support the part of closing and also not easily lost efficacy, and stability is better; And the situation of being partial to not easily appears in up knob when rotating, the stability of rotation is also just better, the use of the user that is more convenient for.
As improving further, the position below described handle upper protruding block is provided with the projection for preventing back-moving spring from exposing again; After then projection is arranged, spring is played to the effect of protection, effectively can prevent the situation of tong, foreign object also not easily has influence on normal deformation and the reset of spring simultaneously, ensures the operating efficiency of spring.
As improving further, described counterbore is truncated cone-shaped hole again, and the aperture of counterbore base is less than the aperture of counterbore opening part; Then the counterbore of this structure makes spring more easily be connected in counterbore, the assembling of the workman that is more convenient for, and in use spring also not easily skids off from counterbore, makes stability in use of the present invention better.
As improving further, described upper clamp nozzle lower surface is provided with and coordinates iron tongue with conductive part again, is provided with heat insulating mattress between described iron tongue and upper clamp nozzle; After then heat insulating mattress is arranged, the heat that iron tongue is produced in the course of the work is not easily transmitted to upper clamp nozzle, and upper clamp nozzle and up knob are integral type structure, therefore heat is also just not easily transmitted on up knob, thus make the temperature of up knob more not easily too high, ensure stability in use of the present invention further.
As improving further again, one end of the nearly hinged place of described conductive part is provided with connecting hole, and conductive part lower end is provided with screwed hole, and described screwed hole is communicated with connecting hole, described heat insulation is provided with and screwed hole through hole one to one, and the aperture of through hole is greater than the aperture of screwed hole; Then the conductive part of this structure is without the need to arranging the syndeton be connected with cable in addition, only need directly to punch on conductive part, not only can reduce raw-material use amount, also reduce the difficulty of processing of conductive part and shorten the process-cycle, and then significantly can reduce the preparation cost of conductive part, thus reduce preparation cost of the present invention.
As further improving, described heat insulation is then provided with protective cover outward; After then protective cover is arranged, can effectively prevent conductive part from exposing and the generation of the security incident caused, make safety in utilization of the present invention higher.
