Detailed Description
The present utility model will be described in further detail below with reference to the drawings and specific embodiments for the understanding of those skilled in the art.
As shown in fig. 1, 2 and 3, a welding head protecting sleeve for carbon dioxide arc welding comprises a sleeve main body 1, wherein one end of the sleeve main body 1 is provided with a first internal thread 11 for connecting with a welding gun, and the other end is butted with an end sleeve 2, and when the welding head protecting sleeve is used, the sleeve main body 1 is fixedly connected with the welding gun through the first thread 11. In order to ensure the reliability of installation, the first thread 11 is a T-shaped thread, which has a large thread clearance and is not affected by slight deformation, thus ensuring smooth disassembly and assembly.
The end sleeve 2 is provided with a connecting part 21 inserted into the sleeve body 1, the connecting part 21 is provided with an external thread 211, and the sleeve body 1 is internally provided with a second internal thread matched with the external thread 211. The external thread 211 is matched with the second internal thread, so that the end sleeve 2 can be conveniently assembled and disassembled with the sleeve main body 1. When the welding tool is used, the end sleeve 2 is close to a welding piece, the service time is long, the end sleeve 2 can be blocked by welding slag, or the end sleeve 2 is locally melted and damaged due to the influence of high temperature caused by touching the welding piece, and the end sleeve 2 is dismounted at the moment, and a new end sleeve 2 can be replaced. The connecting part 21 is inserted into the sleeve main body 1, namely, a section of protective barrier is formed in the sleeve main body 1, so that the sleeve main body 1 can be effectively protected, and the sleeve main body 1 is prevented from being damaged by welding slag splashing. The second internal threads are T-shaped threads, the thread gap is large, the influence of slight deformation is avoided, and even if the end sleeve 2 is slightly deformed under the high temperature condition, the smooth disassembly and assembly of the end sleeve 2 can be ensured.
The connecting portion 21 is provided with an extension protection section 212, and the extension protection section 212 extends outwards from the external thread 211. The extension of the protection segment 212 increases the safety of the protection sleeve body 1 without lengthening the length of the external thread 211. The length of the end sleeve 2 is 25-50mm, the length of the extension protection section 212 is 5-25mm, the length of the end sleeve 2 is saved as much as possible, the sleeve main body 1 can be effectively protected from damage, and the second internal thread on the sleeve main body 1 can be protected under the condition of ensuring the length of the external thread 211 by the length of the extension protection section 212. The external diameter of the end sleeve 2 is larger than that of the sleeve main body 1, and spatter in the welding process can be blocked by the outer ring of the end sleeve 2, so that the outer surface of the sleeve main body 1 is prevented from being spattered and damaged by welding slag.
The sleeve body 1 and the end sleeve 2 are respectively provided with a non-slip protrusion 4, and the non-slip protrusions 4 are convenient for non-slip in the disassembly and assembly process. A spring washer 3 is arranged between the sleeve body 1 and the end sleeve 2, and the spring washer 3 ensures that the sleeve body 1 and the end sleeve 2 are more stable and avoid loosening.
The above embodiments are preferred embodiments of the present utility model, and are not intended to limit the present utility model, and any obvious substitutions are within the scope of the present utility model without departing from the inventive concept of the present utility model.
