Abstract

The present invention provides a Teflon coupling mechanism for a torch body that prevents damage or deformation of the Teflon when coupling it to a welding torch body, and enables the Teflon to be coupled to the torch body stably and quickly by using a Teflon coupling mechanism having a simple configuration, thereby increasing work efficiency. The present invention provides a coupling mechanism for coupling Teflon (3) for insulation to a connecting connector (2) of a torch body, comprising: a body (200) having a cylindrical shape and having a hollow (210) formed inside so that the upper and lower parts penetrate; a support member (300) positioned on the hollow (210) of the body (200) and formed so that the lower part penetrates the lower part of the body (200); and an elastic member (400) positioned on the upper part of the support member (300) on the hollow (210) of the body (200). It is characterized by including a fixing member (500) that is coupled to the upper part of the body (200) and prevents the elastic member (400) from detaching.

Description

Teflon joint mechanism for torch body The present invention relates to a Teflon coupling mechanism for a torch body, and more specifically, to a Teflon coupling mechanism for a torch body that prevents damage or deformation of the Teflon when coupling the Teflon to a welding torch body, and enables the Teflon to be coupled to the torch body stably and quickly by using a Teflon coupling mechanism having a simple configuration, thereby increasing work efficiency. Typically, a CO2 welding torch is a welding device that improves welding quality by preventing oxidation of the molten metal through the release of CO2 gas between the welding wire and the base material while feeding the welding wire, thereby isolating the welding from the atmosphere. And the CO2 welding torch as described above is composed of a torch body (1) in which a connecting part (22) of a gas diffuser (2) having a plurality of diffusion holes (21) is assembled to a connecting hole (11) at one end and a torch cable (101) is assembled to the other end, a torch handle (3) having a built-in trager (not shown in the drawing) configured on the outside of the torch body (1) to allow the user to operate the supply of CO2 gas and welding wire, a tip (102) assembled to one end of the gas diffuser (2), an insulating tube (103) screw-assembled to the outer circumference of the gas diffuser (2), and a cylindrical nozzle (104) assembled to one end of the insulating tube (103) and surrounding the gas diffuser (2) and the tip (102). In the above CO2 welding torch, the torch body (1) is for connecting the gas diffuser and the torch cable, and an insulating member, namely Teflon, is formed on the outside of the connecting connector and the connecting connector for insulation. As shown in FIG. 2, the method of attaching Teflon to the connecting connector of the torch body is to cut the Teflon (11) (see FIG. 2 (a)), place the cut Teflon (11) on the upper part of the connecting connector (12) (see FIG. 2 (b)), and then attach the Teflon (11) to the connecting connector (12) by striking it with a striking member (13), such as a hammer (see FIG. 2 (c)). Afterwards, when the upper part of the Teflon (11) and the upper part of the connecting connector (12) are aligned (see (d) in FIG. 2), a separate pipe (14) is used to position it on the upper part of the Teflon (11), and the upper part of the pipe (14) is struck (see (e) in FIG. 2) to insert the Teflon (11) into the lower part of the connecting connector (12) (see (f) in FIG. 2) so that the connecting connector (12) and the Teflon (11) are joined. As described above, when striking the upper part of the Teflon using a striking member, there is no separate mechanism to support the inner diameter of the Teflon, so the Teflon may be crushed or damaged. Since all such work is performed manually, there is a problem of high worker fatigue and reduced productivity, leading to decreased work efficiency.
