Abstract

The utility model relates to a pair of electric soldering pliers with a protective cover, and the utility model is an improved pair of electric soldering pliers. The structure of the utility model is that the protective cover is arranged on a hand grip sleeve, and the protective cover is used for preventing arc light from baking and welding slag from splashing to burn out welders' gloves.

Description

Electric welding plicers with protective face guard

The utility model is a kind of improved electrode holders.

In the prior art, I see the domestic patent No. at invention " being difficult for the heating electrode holders ": 89215041.6, though it can suppress the main heating factor of electrode holders effectively, it does not prevent the electro-welding arc baking, and welding slag splashes and burns out welder's gloves.There are a kind of " electrode holders of band collet or heat shield " to see domestic number of patent application: 85 2 04252, though it is equipped with protective cover on electrode holders, but it is not a week, but adorned one section heat shield in the part, in welder's welding process, especially execute in the overhead welding process in order to guarantee that welding quality is unlikely to make the weldering liquation to fall down, soldering turret is always wanted the conversion different angles, and this in this case local heat shield is just inoperative.Have a kind of " bar type all position welding pincers " to see domestic number of patent application 90225616.5, it has dish-shaped guard shield at the front end of handle, though it can play certain protective action, it has following shortcoming: if the too small protective action that do not have of 1 guard shield.If the excessive this disc type guard shield of 2 guard shields influences welder's sight line when every root bead bar is soldered near end, in order to guarantee welding quality, make soldering turret and weldment need keep respective angles, the welder has to twist health and makes the body and hands arm can not keep corresponding laborsaving position like this, this spline structure also makes welding rod use up to cause the welding rod waste on the other hand, especially in the work-yard when narrow and small this soldering turret can't use.3, the welder execute when overhead welding welding place, welding rod, soldering turret often can not be point-blank, and to form certain angle, dropping under the effect of electric arc of welding slag often is not vertically to fall, and forms certain radian and fall, and this soldering turret has not just had protective action in these cases.

The utility model purpose will provide a kind of no matter soldering turret, welding rod, welding place to form which type of angle exactly, can both play the electrode holders that protective cover is housed of protective action when especially executing overhead welding.

The utility model is: holding grip (3) at electrode holders and load onto protective cover (2), is will have screw by screw (7) to have a look to have held concurrently and prevent that welding slag from directly falling to being parked in clamping sleeve (1), protective cover (2) on the protective cover (2), holding grip (3) and internally threaded clamp ring (4) links together.Protective cover (2) is that a week is totally-enclosed in the connection of holding on the grip (3), the opening part that is installed in the protective cover of holding on the grip (3) (2) be in protective cover (2) the rear end (holding grip (3) and protective cover (2) junction is a basic point, the welding rod clamping be in the place ahead to.), the shape of protective cover (2) is that the front end section is long-pending little, the rear end section is long-pending big.This structure is applicable to the bar type electrode holders.

The utility model also is: a hole (6) that is used to wear welding rod pressure handle (5) is set on the wall of protective cover (2), and this structure is applicable to the clipping electrode holders of pressure handle.

Because it is tubular that protective cover of the present utility model (2) is taked all totally-enclosed connections and shape, so it can be made by flexible material.Because having to have held concurrently, the front end of protective cover (2) prevents that welding slag from directly stopping to drop on the clamping sleeve (1) on the protective cover (2), again since the utility model in use protective cover (2) thus wall become the arcuation welding slag to be difficult for stopping dropping on the protective cover (2), so to the material of protective cover (2) be chosen in do not need to require on fire-retardant, the heat resistance strict.Because protective cover (2) and hold grip (3) so the effect of connection is only worked than long-pending little many of dish-shaped guard shield section in the junction, again owing to protective cover (2) thus by flexible material make than the electrode holders that dish-shaped guard shield is housed be easy to use many.Since protective cover (2) thus shape be tubular can play comprehensive protective action in use, the electrode holders conversion is arbitrarily angled all can play protective action, especially the welder executes overhead welding and the time more can show its superiority.

Description of drawings:

Fig. 1: the electrode holders structural representation that protective cover is housed.

Fig. 2: A shown in Figure 1 is to schematic diagram.

Clamping sleeve in the utility model (1) can take foil to make, clamping sleeve (1) can be made into one when clamping sleeve (1) endoporus can be passed in protective cover (2) and the front of holding grip (3) junction, otherwise can be made into non-one.Protective cover in the utility model (2) can adopt the flame-proof heat-resistant performance preferably flexible material make.

Claims

1, a kind of electrode holders that protective cover is housed have protective cover (2), hold grip (3), it is characterized in that:

A, protective cover (2) are installed in to be held on the grip (3),

B, protective cover (2) are all totally-enclosed connections holding on the grip (3),

The opening part of c, protective cover (2) is the rear end at protective cover,

The preceding end cross-sectional area of d, protective cover (2) is little, the back end cross-sectional area is big.

2, according to the described a kind of electrode holders that protective cover is housed of claim 1, it is characterized in that on the wall of protective cover (2), being useful on the hole (6) of wearing welding rod pressure handle (5).
