Abstract

The utility model discloses a welding rod lengthening device which comprises a clamping roller, a casing pipe, a spring and a spring bulge, wherein the clamping roller is cone-shaped; a triangle claw is arranged at the thick end of the clamping roller; the casing pipe is sheathed on the clamping roller; both ends of the clamping roller are exposed out of the casing pipe; the thick end of the clamping roller is blocked outside the casing pipe; the spring bulge is arranged at the thin end of the clamping roller; the spring is arranged between the casing pipe and the spring bulge; and a handle is arranged outside the casing pipe; the welding rod lengthening device has the advantages that the welding length of a welding rod is effectively prolonged, the normal welding construction can be carried out in a limited position, and the waste of the welding rod is reduced; and the device is simple in structure and is convenient to produce and maintain.

Description

Welding rod lengthening device

Technical field

The utility model belongs to field of welding devices, relates to a kind of welding rod lengthening device.

Background technology

In the capital construction weld job, because various angles and welding position that steel member overlap joint produces, the electric welder can only utilize the finite length of welding rod; Welding reluctantly; Thereby cause a root bead bar can only weld a part, can only more renew welding rod when length is not enough, increased material cost virtually; And in welding process at ordinary times,, can not welding rod be made the best use of everything, cause waste owing to, during welding rod welding end, blocked by sight line the design reasons of pincers.

The utility model content

The purpose of the utility model is to provide a kind of welding rod lengthening device, in limited position, through prolonging the limited weld length of welding rod, reaches the welding purpose.

The utility model solves the technical scheme that its technical problem adopted:

A kind of welding rod lengthening device is provided, comprises clamping stick, sleeve pipe, spring and spring projection, it is characterized in that: clamping stick becomes cone shape, and the clamping stick butt end is provided with the triangle pawl; Sleeve pipe is placed on the clamping stick, and the two ends of clamping stick are exposed to outside the sleeve pipe, and the clamping stick butt end is blocked in outside the sleeve pipe, and the thin end of clamping stick is provided with the spring projection; Spring is installed between sleeve pipe and the spring projection, and jacket exterior is provided with handle.

Described welding rod lengthening device, the triangle pawl center of clamping stick butt end becomes cylindric hollow.

Described welding rod lengthening device, clamping stick adopts red copper materials processing to form, and sleeve pipe adopts heat-resistant insulation material to process, preferred tetrafluoro ceramic material.

When carrying out weld job, welding rod lengthening device can be held welding rod by a head-clamp, and other end and electric weld handle clipper joint have effectively prolonged the weld length of welding rod through above indirect connection, reach the purpose of welding procedure.

The advantage of the utility model is: effectively prolonged the weld length of welding rod, can normally carry out welding procedure in constrained position, and reduced the waste of welding rod; This device structure is simple simultaneously, is convenient to produce and safeguard.

Among the figure: 1, clamping stick; 2, sleeve pipe; 3, spring; 4, spring projection; 5, triangle pawl; 6, handle.

The specific embodiment

Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:

Of Fig. 1-3, the utility model comprises clamping stick 1, sleeve pipe 2, spring 3 and spring projection 4,1 one-tenth cone shape of clamping stick, and clamping stick 1 butt end is provided with triangle pawl 5; Sleeve pipe 2 is placed on the clamping stick 1, and the two ends of clamping stick 1 are exposed to outside the sleeve pipe 2, and clamping stick 1 butt end is blocked in outside the sleeve pipe 2, and the thin end of clamping stick 1 is provided with spring projection 4; Spring 3 is installed between sleeve pipe 2 and the spring projection 4, and sleeve pipe 2 outer setting have handle 6.

The factor of electric current heating when considering welding, use has satisfactory electrical conductivity and stable on heating red copper is done raw material, is processed into the clamping stick 1 that has a little cone shape; Be processed into the thickness of one welding rod at the thinner end of cone, can be clipped on the electric weld handle pincers as welding rod easily; At the other end of cone, the triangle pawl 5 that is processed into 4 centimetre lengths is cut in a just thicker end-grain cutting, and triangle pawl 5 central parts are processed into hollow cylinder, just can put into welding rod so in use.

Use material heat-resisting and insulation, like the tetrafluoro ceramic material, be processed into a sleeve pipe 2, the diameter of sleeve pipe 2 is slightly thinner than clamping stick 1 butt end, and sleeve pipe 2 can be put into from a thin end, promotes triangle pawl 5 closures, and can not deviate from from a thick end.

The thin end of clamping stick 1 is provided with spring projection 4, and sleeve pipe 2 outer setting have handle 6, and spring 3 is installed between sleeve pipe 2 and the spring projection 4; Only need handle 6 to pull back in use, drive sleeve pipe 2 compression springs 3, sleeve pipe 2 promptly separates with triangle pawl 5 parts of clamping stick 1, and triangle pawl 5 is able to open, and makes it to change welding rod; Release handle 6 after finishing, the spring 3 that is in compressive state produces elastic force promotion sleeve pipes 2 and moves forward, and makes triangle pawl 5 closures of cone base, thereby steps up welding rod, is used for welding.
