Abstract

The utility model relates to a pair of screw-fastening electric welding pliers which are composed of a screw, a screw head, a housing insert, a handle housing, a handle, etc. The utility model overcomes the malady that the electric welding rod of the electric welding pliers is difficult to load. When the electric welding rod is loaded and unloaded, a handle body is just needed to rotate towards a left side or a right side, which is easy and labor-saving, the electric welding rod can be loaded into two different angles of 45 DEG or 90 DEG, and users can automatically select welding direction according to different conditions of working environment, which is a welding requirement accommodating industry such as shipbuilding, chemical industry, building industry, etc.

Description

Screw-fastening electric welding handle

The utility model is that a kind of screw rod tightens up the formula electric weld handle, belongs to electric welding tool kind.

Known to the designer, at present domestic and international electrode holders adopt spring to clamp the formula electrode holders mostly, and this electrode holders weld after relying on spring force to clamp welding rod, and its elastic force is very strong, extremely require great effort when the compression spring is gone into welding rod.

The purpose of this utility model is that a kind of screw rod of design tightens up the formula electric weld handle, as long as handle is left-handed, very light laborsaving, and welding rod can dress up 90 ° or 45 ° of two kinds of different angles, carries out freely selecting according to work characteristics and requirement during welding rod in loading and unloading.Therefore the utlity model has easy to loading and unloadingly, welding rod angle can be selected advantage voluntarily according to the working environment difference.

The utility model is achieved like this, overall structure has the cylindrical shape handle body, be split into rotational circle tubular handle body when axially welding rods at 45 and 90 ° are assigned the hole on screw rod, screw head, case inserts and the handle respectively, make the screw rod rotation, the augering screw head, welding rod is tightly withstood, after with the reverse rotation of cylinder handle body, withdraw from screw head, loosen welding rod, can take out, welding rod can have two kinds of different angles available to the Worker's Stadium, promptly 45 ° or 90 °, at this moment,, welding rod assigns the hole as long as being inserted corresponding welding rod.

Below in conjunction with accompanying drawing the utility model is done an into fixed step explanation;

Fig. 1 screw rod tightens up electric weld handle general structure cutaway view.

Fig. 2 is the handle body schematic diagram.

Fig. 3 is the screw rod schematic diagram.

Fig. 4 is the screw head schematic diagram.

Fig. 5 be the structural representation of handle casing structure to.

Fig. 6 is a shell inlay schematic diagram.

With reference to figure 1-5, the utility model handle casing 1, shell inlay 2, screw head 3, the parts such as screw rod 4 and handle body 5 form, handle body is a cylinder that forms with rubber die casting, in order to prevent rolling, at many ribs of cylinder body outer wall or groove, the inwall of cylindrical shell is a regular hexagon column casing body with varying cross-section size, in regular hexagon column casing body, insert screw rod 4, screw rod 4 is one and forms with the turning of H62 hexagonal brass rod, at hexagon prism cylindrical shell end, a screw is housed, in order to tighten up power line, and at the threaded tip of screw rod 4 screw head 3 of packing into, screw head is that an end becomes cylinder, the other end is cone shape, and the cone head made have certain garden arc fluting, in order to tighten up the welding rod of garden shape, in screw rod 4 and screw head 3 outsides, case inserts 2 is screwed on the screw rod 4, and case inserts 2 is spherical Cylinders that form with the turning of H62 brass bar. And have many grooves at the outer wall of Cylinder end, to increase the friction with handle casing, at the spheric end of case inserts 2, have two with axial at 45 ° and 90 ° assign the hole, for the welding rod usefulness of packing into. The center is post hole, a garden. At its skin, be one with the handle casing 1 of plastic injection-moulded one-tenth of PF, handle casing 1 and case inserts phase tight fit, and have in corresponding position with axial at 45 ° and 90 ° two and assign the hole, with assign the hole corresponding on the case inserts 2, its outer wall has four and half garden shape fins.

Describe in detail for embodiment: screw rod tightens up formula electric weld handle total length 215m, and handle body is a hexagon cylinder garden cylindrical shell in the rubber of Φ a 33 * 130mm is cast into, and screw rod is by H62 hexagonal brass body, total length 129.5mm, and screw head is by T ₈Material constitutes, and the top that is installed in screw rod also screws in the outer casing member in the lump, and case inserts is the spherical Cylinder of a brass body, total length 63mm, the radius of a ball are 9mm, and handle casing is black PF plastics cylinders, the long 93mm of handle, the end radius of a ball are 20mm, and its outer wall has four and half garden column convex ribs.

Claims

1, a kind of screw rod of being made up of handle and shell tightens up the formula electric weld handle, it is characterized in that: the screw rod of packing in the garden shape handle body is arranged, the head of screw rod has a screw head, and is enclosed within screw rod and screw head outside at the shell inlay, has two welding rod jacks on the shell inlay.

2, electric weld handle according to claim 1 is characterized in that: be split into respectively on case inserts and the handle casing with axial at 45 and 90 ° of welding rods and assign the hole.

3, electric weld handle according to claim 2 is characterized in that: handle body is a garden cylindrical shell that is cast into rubber, and cylinder body outer wall is many ribs or groove, and cylinder inboard wall is the regular hexagon column casing body with varying cross-section size.

4, electric weld handle according to claim 3 is characterized in that: screw rod is the hexagonal cylinder of a H62 brass, on its top screw head is housed, it is that one one end becomes Cylinder, the other end is a cone, and the cone head is made certain garden arc fluting, so that withstand the welding rod of garden shape.
