Abstract
The utility model relates to electric welding pliers preventing a hand from being scalded. The electric welding pliers comprise a sleeve, a welding nozzle, an electric conductor and an electric conductor pressing rod. The front end of the sleeve is connected with the welding nozzle, the electric conductor is arranged in the welding nozzle, and the electric conductor pressing rod is rotatably connected with the electric conductor through a bolt. The electric welding pliers preventing the hand from being scalded are characterized in that a hollow handle is connected to the rear end of the sleeve, an inner cavity of the handle is communicated with an inner cavity of the sleeve, a 90-degree included angle is formed between the handle and the sleeve, and a groove is formed in the electric conductor in the direction of the sleeve. According to the electric welding pliers preventing the hand from being scalded, by means of the reasonable arrangement of the direction of the groove in the electric conductor and the included angle between the handle and the sleeve, the temperature of the handle is low, and the electric welding pliers preventing the hand from being scalded have the advantages of being capable of effectively preventing the back of the hand of a user from being scalded.
Description
Technical field
The utility model relates to the welding set technical field, particularly a kind of hand scald-preventing electric welding tongs.
Background technology
Electrode holders are a kind of soldering appliances commonly used, in operating process, because electric conductor has certain resistance, can produce certain heat after energising.It is larger that the jaw position of tip particularly, electric conductor and welding rod contact heat-dissipating, and temperature is also the highest.Thermal insulation layer and handle all are fastened on electric conductor, so it is very fast to conduct heat, and dissipation of heat is not gone out.Weld interval one is long, and the electrode holders handle just can be hot, and it is hot that the operator can feel in use, thereby affected operating efficiency, and easily scald.In order to solve this technical problem, in existing product, use double-deck handle, namely between electric conductor and outer handle, increased one deck thermal insulation layer, as the internal layer handle, but the cooling-down effect of this double-deck handle is unsatisfactory, reason is that the radiating effect of this structure is bad.And the contact area of outer handle and thermal insulation layer and electric conductor is larger, atmosphere draught-free, make cooling-down effect have a greatly reduced quality.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of simple in structure, and thermal diffusivity is good, has the electrode holders of burn prevention function.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of hand scald-preventing electric welding tongs, comprise sleeve, tip, electric conductor and electric conductor depression bar, barrel forward end connects tip, and electric conductor is placed in tip, and the electric conductor depression bar is rotationally connected by bolt and electric conductor, it is characterized in that: described sleeve rear end also connects the handle of a hollow, intracavity of handle is communicated with barrel bore, and handle and sleeve are 90 ° of angles, along the sleeve direction, are provided with groove on described electric conductor.
The width of described groove is less than 2.5 mm.When electric conductor and electric conductor depression bar clamp most of welding rod like this, can not skid.
The utility model is arranged at a handle by the rear end at sleeve, and in vertical state, and the inner chamber of sleeve is communicated with the inner chamber of the back of the hand for this handle and sleeve, and so both the convenient electric wire that connects, facilitated circulation of air simultaneously.Electric conductor arranges groove along the sleeve direction, convenient clamping welding rod, and the direction of welding rod is identical with the sleeve direction.During electrode holders work, electric conductor and sleeve generally are in the place that location comparison is high, handle is in the place that location comparison is low, the heat that the electric conductor place produces makes ambient air temperature improve, pressure decreased, the air themperature of handle is low, pressure is high, the air at handle place moves to the electric conductor place like this, has so just formed wind, with the heat at electric conductor place, because wind is flowed to the electric conductor place by handle, so the handle temperature can be too not high, be conducive to reduce the stable of handle, prevent hot user's hand.
In sum, the utility model, by groove direction on electric conductor and the angle of handle and sleeve rationally are set, makes the handle temperature lower, has the beneficial effect that the back of the hand that can effectively prevent the user is scalded.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Specific embodiment
As shown in Figure 1, a kind of hand scald-preventing electric welding tongs, comprise sleeve 5, tip 1, electric conductor 4 and electric conductor depression bar 2, sleeve 5 front ends connect tip 1, and electric conductor 4 is placed in tip 1, and electric conductor depression bar 2 is rotationally connected by bolt and electric conductor 4, described sleeve 5 rear ends also connect the handle 6 of a hollow, handle 6 inner chambers are communicated with sleeve 5 inner chambers, and handle 6 is 90 ° of angles with sleeve 5, along sleeve 5 directions, is provided with groove 3 on described electric conductor 4.The width of described groove 3 is less than 2.5 mm, can not skid when electric conductor and electric conductor depression bar clamp most of welding rod like this.
Claims (2)
1. hand scald-preventing electric welding tongs, comprise sleeve, tip, electric conductor and electric conductor depression bar, barrel forward end connects tip, electric conductor is placed in tip, the electric conductor depression bar is rotationally connected by bolt and electric conductor, it is characterized in that: described sleeve rear end also connects the handle of a hollow, and intracavity of handle is communicated with barrel bore, handle and sleeve are 90 ° of angles, along the sleeve direction, are provided with groove on described electric conductor.
2. hand scald-preventing electric welding tongs according to claim 1, it is characterized in that: the width of described groove is less than 2.5 mm.
