Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited by the following detailed description.

Referring to fig. 1, a first embodiment of the present invention provides a protective sleeve 1 for a gun head of a welding gun, including a gun tube 11 and a protective ring 12, wherein one end of the gun tube 11 is connected to the gun head, an opposite end of the gun tube is sleeved on an outer peripheral side of the protective ring 12, one end of the protective ring 12 is exposed out of the gun tube 11, and an opposite end of the protective ring is provided with a clamping portion 121. The clamping portion 121 is a groove structure inward of the surface of the protection ring 12, the surface of the barrel 11 is further inserted with a limiting member 111, the limiting member 111 can move in the radial direction of the barrel 11 relative to the surface of the barrel 11, the limiting member 111 can be disposed in the clamping portion 121, that is, when the limiting member 111 is disposed in the clamping portion 121, the limiting member 111 positions the protection ring 12 at a specified position in the barrel 11 to prevent the protection ring from falling off.

It can be understood that place in the protection ring 12 in the barrel 11 and part expose in the barrel 11 for when the user is welding operation, the welding slag that splashes can adhere to the inner periphery side of protection ring 12, the user's accessible removes locating part 111 makes locating part 111 keeps away from joint portion 121, with alone will carry out the scarfing cinder operation after protection ring 12 is dismantled, or directly change the protection ring 12 of renewing, made things convenient for the user to use, avoided directly clearing up barrel 11, improved barrel 11's life, also avoided directly changing barrel 11, reduced manufacturing cost, improved work efficiency.
