Abstract
The utility model relates to an electric arc welding device, in particular to an electrode holder, which comprises an external handle sleeve, a welding nozzle, an electric conductor and an electric conductor compression rod, wherein the electric conductor is arranged in the welding nozzle, and the electric conductor compression rod is rotatably connected with the electric conductor through a screw bolt. The device is characterized in that the rear end of the welding nozzle is a U-shaped inner handle, the U-shaped inner handle and the welding nozzle are a fixed integral assembly, and the U-shaped inner handle is inserted into the external handle sleeve. A spring blade is connected between the electric conductor and the external handle sleeve, and an insulating pad is further arranged between the spring blade and the electric conductor. A groove is arranged on the inner wall of the front end of the external handle sleeve, one end of the spring blade is fixed in the groove, and the other end is connected with the electric conductor through the insulating pad. The rear end of the welding nozzle of the electric arc welding device is the U-shaped inner handle which is directly inserted into the external handle sleeve, the assembly is very convenient, and the space between the inner handle and the external handle is added, the heat dissipating effect is improved, thereby the temperature of the handle is reduced, and the handle is no longer hot to touch.
Description
Technical field
The utility model relates to arc-welding apparatus, particularly a kind of electrode holders.
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 the energising.The jaw position of tip particularly, electric conductor contact with welding rod that to give birth to heat bigger, and temperature is also the highest.Thermal insulation layer and handle all are fastened on the electric conductor, so it is very fast to conduct heat, and heat distributes and do not go 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 influenced operating efficiency, and scald easily.In order to solve this technical problem, used double-deck handle in the existing product, promptly increased one deck thermal insulation layer between electric conductor and the outer handle, as the internal layer handle, but the cooling-down effect of this double-deck handle is unsatisfactory, and 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 bigger, and atmosphere draught-free makes cooling-down effect have a greatly reduced quality.Be connected by screw between internal layer handle and outer handle and the tip, this structure is also more loaded down with trivial details in assembling process, time-consuming consumption power.
Summary of the invention
The technical problems to be solved in the utility model is: the electrode holders heating is scalded one's hand, and assembles loaded down with trivial details technical problem.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: electrode holders, comprise outer sleeve tube, tip, electric conductor and electric conductor depression bar, electric conductor places in the tip, the electric conductor depression bar is rotationally connected by bolt and electric conductor, it is characterized in that: described tip rear end is a handle in the U-shaped, and handle and tip are a fixing whole accessory in the described U-shaped, and handle is plugged in the outer sleeve tube in the U-shaped.
As further improvement of the utility model, be connected with spring leaf between described electric conductor and the outer sleeve tube.
Further, also be provided with heat insulating mattress between described spring leaf and the electric conductor.
Described outer sleeve tube front inner wall is provided with groove, and described spring leaf one end is fixed in this groove, and the other end is connected with electric conductor by described heat insulating mattress.
Handle is become after reaming half vertically by cylinder in the described U-shaped.
The handle outer wall is provided with plurality of strengthening ribs in the described U-shaped, and described outer sleeve tube front inner wall also is provided with the fixed block that matches with reinforcement.
The rear end of described electric conductor is provided with two wiring holes.
As further improvement of the utility model, handle is become after reaming half vertically by cylinder in the described flute profile.
Tip of the present utility model rear end is a handle in the U-shaped, directly is plugged on the outer sleeve tube, assembles very convenient.Adopt the interior handle of U-shaped to be connected, and on the handle outer wall reinforcement is set in the U-shaped, reduced the contact area of outer handle and interior handle, reduced hot conduction with outer sleeve tube; Increased the space between interior handle and the outer handle simultaneously, made and circulation of air improved radiating effect, further reduced the temperature of handle, made handle no longer hot.
