[0033] Refer to the attached Figure 1-4 A protective structure for welding steel, comprising a fixed protective ring 1, a square steel body 11 is arranged inside the fixed protective ring 1, a side plate 2 is arranged on the outer wall of the fixed protective ring 1, an exhaust pipe 3 is arranged inside one side of the side plate 2, a suction cup 4 is arranged at the bottom of the exhaust pipe 3, a connecting bolt 5 is arranged inside the exhaust pipe 3, the connecting bolt 5 is threadedly connected to the exhaust pipe 3, the suction cup 4 is fitted with the square steel body 11, a second guide groove 7 is opened on the outer wall of the fixed protective ring 1, a limiting groove 8 is opened on the inner wall of the second guide groove 7, a connecting structure 9 is slidably connected inside the second guide groove 7, and a first guide groove 6 is opened on the outer wall of the side plate 2;

[0034] The number of the fixed protection rings 1 is set to two, the two fixed protection rings 1 are connected by a connecting structure 9 , and a welding protection structure 10 is arranged between the two fixed protection rings 1 .

[0035] Furthermore, the number of the second guide grooves 7 is set to four, and the four second guide grooves 7 are distributed on four outer walls of the fixed protection ring 1, and the cross-section of the fixed protection ring 1 is set to be a square.

[0036] Furthermore, the connecting structure 9 includes a push rod 901, a mounting block 902 is provided on the top of the push rod 901, limit strips 903 are provided on both sides of the inner wall of the mounting block 902, a spring is provided between the two limit strips 903, the limit strips 903 are engaged with the limit groove 8, a connecting shaft 904 is provided at one end of the push rod 901, an external thread 905 is provided on the outer wall of the connecting shaft 904, a fixing nut 906 is provided on the outer wall of the connecting shaft 904, and the fixing nut The female thread 906 is connected to the external thread 905, pushing the connecting structure 9 in the fixed protective ring 1 on both sides inward, so that the limiting strip 903 engages with the limiting groove 8 to fix the position of the connecting structure 9 on both sides, and one end of the connecting shafts 904 on both sides fits against each other and rotates the fixing nut 906 on the outer wall of the connecting shaft 904, and the fixing nut 906 enters the outer wall between the two connecting shafts 904, thereby connecting the two connecting structures 9 and fixing the position of the square steel body 11 set inside the fixed protective ring 1.

[0037] Furthermore, the welding protection structure 10 includes a protection plate 1001, which is arranged between the two fixed protection rings 1, and a mounting groove 1002 is opened in the middle of the protection plate 1001, and a slider 1003 is slidably connected inside the mounting groove 1002, and a connecting hole 1004 is opened in the middle of the slider 1003. After the fixed protection ring 1 and the connecting structure 9 fix the square steel body 11, the protection plate 1001 is placed between the two fixed protection rings 1, and then the welding rod is inserted into the inside of the connecting hole 1004, so that the welding rod in the welding device welds the two square steel bodies 11, and the sparks generated during the welding process splash onto the inner wall of the protection plate 1001 and the fixed protection ring 1, and block the protection plate 1001 and the fixed protection ring 1 to prevent the sparks from splashing out. At the same time, when the welding device moves, it can drive the slider 1003 to move inside the mounting groove 1002, which is used to adjust the position of the slider 1003 so that the welding rod is always aligned between the two square steel bodies 11.

[0038] In this embodiment, when it is necessary to weld the two square steel bodies 11 together, the two square steel bodies 11 are respectively installed inside the fixed protective ring 1, so that the suction cup 4 fits with the outer wall of the fixed protective ring 1, and then the connecting bolt 5 is rotated to make the suction cup 4 fit with the outer wall of the fixed protective ring 1, and then the two fixed protective rings 1 are placed in the same horizontal plane, and the mounting block 902 is pushed to move inward inside the limiting groove 8, so that the limiting strip 903 passes through the limiting groove 8 in turn and squeezes the spring. When the two connecting shafts 904 fit each other, the spring pushes the limiting strip 903 to reset and engage with the limiting groove 8, and the fixing nut 906 is manually rotated, and the fixing nut 906 is connected to the external thread 905 on the outer wall of the connecting shaft 904 on the other side, so that the two connecting structures 9 are connected to each other to fix the fixed protective ring 1 and the internal square steel body 11;

[0039] Then put the protective plate 1001 between the two fixed protective rings 1, and the connecting structure 9 directly below the fixed protective ring 1 is not connected to prevent the connecting structure 9 from blocking the welding. The connecting structures 9 on the other three surfaces are connected to each other, and then the welding rod in the welding device is inserted into the interior of the connecting hole 1004. When the welding device moves, the slider 1003 is driven to slide on the inner wall of the mounting groove 1002 to guide the welding device. When the cross-sectional area of the square steel body 11 is large and all four surfaces need to be welded, remove the protective plate 1001, connect the connecting structures 9 on the welded surfaces to each other, and then separate the connecting structures 9 on the surfaces that need to be welded, repeat the above-mentioned parts operation to weld the other surfaces of the square steel body 11, and the sparks generated during the welding process are blocked by the protective plate 1001 and the fixed protective ring 1 to prevent sparks from splashing out.

[0040] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
