[0002] In the field of welding technology, the electrode arm is a crucial component of welding equipment, supporting the welding head for welding operations. However, traditional electrode arms often lack sufficient protection during welding, especially in high-temperature and spark-splashing environments, making them susceptible to damage and even potential fires or other safety accidents. Furthermore, poor current conduction during use can lead to a decline in weld quality. Utility Model Content

[0018] Please see Figures 1-5 In this embodiment of the invention, the electrode arm with a flame-retardant protective strip includes a horizontal bar 1. One end of the horizontal bar 1 is fixedly connected to a bend 3. The end of the bend 3 away from the horizontal bar 1 is fixedly connected to a vertical bar 4. A welding head 5 is provided at the end of the vertical bar 4 away from the bend 3. An electric wire 2 is fixedly connected through the end of the horizontal bar 1 away from the bend 3 to provide current to the welding head 5.

[0019] Both the outer walls of the horizontal bar 1 and the vertical bar 4 are equipped with protective strips 6, such as Figure 4 and Figure 5 As shown, a protective inner cavity 61 is formed through the inner wall of the protective strip 6, and both the horizontal bar 1 and the vertical bar 4 are located inside the protective inner cavity 61. An insulating layer 62 is provided at one end of the protective strip 6 near the protective inner cavity 61, and a fireproof layer 63 is fixedly connected to the outer wall of the insulating layer 62. A heat insulation layer 64 is fixedly connected to the outer wall of the fireproof layer 63, and a flexible protective layer 65 is fixedly connected to the outer wall of the heat insulation layer 64. This multi-layered structural design enables the protective strip 6 to have multiple functions such as flame retardancy, heat insulation, and flexible protection.

[0020] Each of the two protective straps 6, located at opposite ends, is equipped with a fixing component 7 to secure the protective straps 6 to the electrode arm. Figure 3 As shown, the fixing assembly 7 includes a fixing ring 71, with a through hole 72 on its inner wall. Two protective strips 6 are disposed inside the through hole 72. Multiple connecting blocks 73 are fixedly connected to the outer wall of the fixing ring 71 through one end. Each connecting block 73 is threadedly connected to the others with a fastening bolt 74. By tightening the fastening bolts 74, the fixing ring 71 and the protective strips 6 can be securely fixed to the electrode arm.

[0021] Among them, the insulation layer 62 can be made of materials such as rubber, plastic (such as polyvinyl chloride, polyethylene, etc.), ceramics and glass fiber; the fireproof layer 63 can be made of materials such as flame-retardant fiber, flame-retardant coating, inorganic fireproof material, etc.; the heat insulation layer 64 can be made of materials such as aerogel, foam material (such as polyurethane foam, polystyrene foam, etc.), aluminum silicate fiber, etc.; the flexible protective layer 65 can be made of materials such as high temperature resistant rubber, flame-retardant fabric (such as flame-retardant cotton cloth, flame-retardant synthetic fiber cloth, etc.), high temperature silicone, etc.

[0022] The working principle of this invention is as follows: The electrode arm mainly consists of a horizontal bar 1, a bend 3, a vertical bar 4, and a welding head 5. One end of the horizontal bar 1 is connected to the vertical bar 4 via the bend 3, and the welding head 5 is installed at the end of the vertical bar 4. This structure allows the welding head 5 to be flexibly positioned at the welding location. The end of the horizontal bar 1 away from the bend 3 is connected to a power source via a wire 2 to provide the necessary current to the welding head 5.

[0023] The protective strip 6 is the core component of this invention, tightly wrapping around the outer walls of the horizontal bar 1 and the vertical bar 4. The protective strip 6 has a multi-layered protective structure, including an insulation layer 62, a fireproof layer 63, a heat insulation layer 64, and a flexible protective layer 65. When the welding head 5 is working, it generates high temperatures and sparks. These high temperatures and sparks first come into contact with the flexible protective layer 65 of the protective strip 6. This layer material has certain high-temperature resistance and flame-retardant properties, which can initially block the transfer of heat and the splashing of sparks.

[0024] If heat penetrates the flexible protective layer 65, it will next encounter the heat insulation layer 64. The heat insulation layer 64 is made of a high thermal resistance material, which can effectively reduce the rate of heat transfer and further protect the electrode arm from high temperatures.

[0025] If the heat continues to transfer inward, it will encounter the fireproof layer 63. The fireproof layer 63 is made of flame-retardant material and will not burn even at high temperatures, thus cutting off the path of the flame to spread into the electrode arm.

[0026] The innermost insulating layer 62 ensures that the current is not lost or short-circuited due to the material of the electrode arm during transmission, guaranteeing welding quality and current stability. The protective band 6 is fixed to the electrode arm by the fixing assembly 7. The fixing assembly 7 includes a fixing ring 71, a through hole 72, a connecting block 73, and a fastening bolt 74.

[0027] The protective strap 6 passes through the through hole 72 of the retaining ring 71, and the retaining ring 71 and the connecting block 73 are tightly locked to the electrode arm by the fastening bolt 74. This structure ensures that the protective strap 6 will not fall off or loosen during use, thereby maintaining the overall stability and safety of the electrode arm.
