Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time:

[0018] Embodiment 1:

[0019] Reference Figure 1-Figure 7 According to an embodiment of the utility model, a welding work protection absorption box comprises two fixed arc boxes 10 distributed up and down, the left ends of the two fixed arc boxes 10 are connected by a hinged rod, and the right ends of the two fixed arc boxes 10 are fixedly provided with a mounting plate 11, and a threaded fixing hole is provided on the mounting plate 11. The two fixed arc boxes 10 are both opened forward, and a collecting chamber 25 is provided in the two fixed arc boxes 10. A group of guide slides 20 are fixed in each collecting chamber 25, and each group of guide slides 20 is connected to a filter screen 12 and a collection protection box 22 that can slide back and forth. The filter screen 12 is arranged in a double layer front and back, and the front end of each group of guide slides 20 is hinged with an abutment plate 21, and a torsion spring is provided at the hinged part of the guide slide 20 and the abutment plate 21. The ends of the two fixed arc boxes 10 that are far away from each other are fixedly provided with exhaust fans 13, and on the circumferential surface of the fixed arc boxes 10, A connecting chamber 23 is provided at the exhaust fan 13, and the connecting chamber 23 is communicated with the collecting chamber 25. A baffle 24 is provided in the collecting chamber 25 and in the upper and lower areas of the exhaust fan 13. The baffle 24 is L-shaped and abuts against the filter screen 12. The collecting protection box 22 is symmetrical on the left and right, and the opening is arranged forward. The collecting protection box 22 abuts against the baffle 24. A filter plate is provided at the abutment between the collecting protection box 22 and the baffle 24. Two symmetrical hinge seats 14 are fixed on the inner circumference of the two fixed arc boxes 10. Each hinge seat 14 is rotatably connected to an hinge frame 15. Each hinge frame 15 is connected to a hinge rod 16. A torsion spring connecting rod 17 is connected between the hinge frame 15 and the hinge rod 16. A spring telescopic frame 18 is provided between the hinge frame 15 and the hinge rod 16. An abutting wheel 19 is rotatably connected to each hinge rod 16.

[0020] Two pipes are placed so that the pipes are butted against each other on the left and right sides. A welding mechanism is provided at the butting part of the two pipes for welding. A fixed arc box 10 is placed at one end of the pipe. At this time, the two fixed arc boxes 10 are in an open state. The user pushes the two fixed arc boxes 10 to make the two fixed arc boxes 10 approach each other. The fixed arc boxes 10 swing toward each other through the hinge rod at the left end, so that the mounting plates 11 at the right end of the fixed arc boxes 10 abut against each other. Threaded fixings are installed at the threaded fixing holes of the mounting plates 11 for fixed installation. The two fixed arc boxes 10 approach each other as shown in FIG. Figure 1As shown, the articulated frame 15, the articulated rod 16 and the abutting wheel 19 arranged on the inner periphery of the fixed arc box 10 abut against the peripheral surface of the pipeline under the action of the spring force. According to the radius of the pipeline in the abutting state, the angle between the articulated frame 15 and the articulated rod 16 also changes accordingly. The articulated frame 15 and the articulated rod 16 overcome the torsion spring force at the torsion spring connecting rod 17, and the articulated rod 16 overcomes the spring force at the spring telescopic frame 18 to tilt. The larger the radius of the pipeline, the smaller the angle between the articulated frame 15 and the articulated rod 16, and the abutting wheel 19 abuts against the outer peripheral surface of the pipeline through the support of the spring force.

[0021] The upper and lower exhaust fans 13 are powered on and working. Through the connection between the connecting chamber 23 and the collecting chamber 25, the filter plate at the collecting protection box 22 is connected, and the air is drawn into the collecting chamber 25 from the front end of the fixed arc box 10. The air carries the smoke and scattered sparks generated during the welding process and enters the collecting chamber 25 through the filtration of the filter screen 12. The air is filtered by the filter screen 12 and flows to the collecting protection box 22. From the collecting protection box 22, it flows upward or downward to the filter plate at the abutment part of the collecting protection box 22 and the baffle 24, flows through the filter plate to the connecting chamber 23, and is discharged outward by the exhaust fan 13.

[0022] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
