The frame 2 to be welded includes an outer frame 201 and connecting rods 202. A transverse support rod 3 and a vertical support rod 4 are fixedly connected to the interior of the fixing frame 1. The transverse support rod 3 and the vertical support rod 4 each have a first retaining groove formed therein to mate with the outer frame 201. The vertical support rod 4 has a second retaining groove formed therein to mate with the connecting rod 202. The first and second retaining grooves can be used to securely limit the position of the outer frame 201 and the connecting rod 202, thereby facilitating subsequent welding of the outer frame 201 and the connecting rod 202 by staff.

[0034] Furthermore, a first handle 15 is fixedly mounted on the outer surface of the fixed frame 1, which facilitates handling and turning of the fixed frame 1. A plurality of stoppers 16 are symmetrically mounted on the inner wall of the fixed frame 1. The ends of the connecting rod 202 can contact the stoppers 16, which limit the position of the connecting rod 202 and further improve the welding accuracy between the connecting rod 202 and the outer frame 201.

[0035] Furthermore, a purification box 5 is fixedly installed at the bottom of the fixed frame 1, and interconnected air inlet slots are provided inside the fixed frame 1 and the purification box 5. A coarse filter 13 is fixedly installed on the inner wall of the air inlet slot opened inside the fixed frame 1. The coarse filter 13 can reduce the entry of larger external objects and impurities into the air inlet slot, causing blockage of the air inlet slot.

[0036] Furthermore, an exhaust fan 6 is fixedly installed on one side of the purification box 5, and the air inlet end of the exhaust fan 6 passes through the interior of the purification box 5. The interior of the purification box 5 is slidably connected to a purification drawer 7, and a card block 14 is fixedly installed on the inner side surface of the purification drawer 7. The inner wall of the purification box 5 is provided with a card slot adapted to the card block 14. The card block 14 and the card slot can increase the contact area between the purification drawer 7 and the purification box 5, and can make the connection between the purification drawer 7 and the purification box 5 more stable.

[0037] Furthermore, the inner wall of the purification drawer 7 is provided with a purification assembly 8, which includes a fine filter 81 and an activated carbon mesh 82. The fine filter 81 and the activated carbon mesh 82 are both mounted on the inner wall of the purification drawer 7. The fine filter 81 can filter some solid particulate impurities in the welding gas, and the activated carbon mesh 82 can adsorb carbon monoxide in the welding gas, thereby reducing the high carbon monoxide concentration in the air, which in turn affects the health of workers.

[0038] Furthermore, a mounting groove is provided inside the clean drawer 7. A spring 9 is fixedly installed on the inner wall of the mounting groove provided inside the clean drawer 7. A semicircular block 10 is fixedly installed on one end of the spring 9. A semicircular slot that matches the semicircular block 10 is provided inside the clean box 5. A slider is fixedly installed on the outer surface of the semicircular block 10. A chute that matches the slider is provided inside the clean drawer 7. The slider and chute can limit the range of movement of the semicircular block 10 and make the semicircular block 10 move more smoothly. A pull groove is provided on the outer side of the clean drawer 7. A second handle 17 is fixedly installed on the inner wall of the pull groove provided inside the clean drawer 7. The second handle 17 can facilitate the staff to pull out the clean drawer 7. When the fine filter 81 and the activated carbon net 82 need to be cleaned or replaced, the staff can pull the second handle 17, and the second handle 17 can drive the purification drawer 7 to move outward. At the same time, the semicircular block 10 can be squeezed by the purification box 5 to push the spring 9 to compress, so that the staff can quickly pull out the purification drawer 7 and clean or replace the fine filter 81 and the activated carbon net 82.

[0039] Furthermore, a base 11 is fixedly installed on the outer surface of the fixed frame 1, and a pressure rod 12 is rotatably connected to the inside of the base 11 through a damping shaft. The pressure rod 12 can contact the outer frame 201 and the connecting rod 202. During use, the staff can lower the pressure rod 12 through the base 11 and the damping shaft to contact the outer frame 201 and the connecting rod 202, so that the fixed frame 1 can be flipped, which makes it more convenient for the staff to flip the outer frame 201 and the connecting rod 202.

[0040] The implementation principle of the present utility model is as follows: when in use, the staff can put the connecting rod 202 to be welded into the second slot provided in the vertical support rod 4, and the limit block 16 and the second slot can limit the position of the connecting rod 202 to reduce shaking during welding. Afterwards, the staff can put the outer frame 201 to be welded into the first slot provided in the horizontal support rod 3 and the vertical support rod 4. The first slot can fix the position of the outer frame 201, and then weld the connection between the connecting rod 202 and the outer frame 201, thereby improving welding accuracy and welding efficiency. In addition, during use, the staff can lower the pressure rod 12 through the base 11 and the damping shaft to contact the outer frame 201 and the connecting rod 202, so that the fixed frame 1 can be turned over, which is more convenient for the staff to weld the outer frame 201 and the connecting rod 202.

[0041] During welding, the staff can start the exhaust fan 6, which can draw the smoke generated by welding into the purification box 5 through the air inlet slot. The fine filter 81 and the activated carbon net 82 inside the purification box 5 can filter the smoke. The fine filter 81 can filter some solid particle impurities in the welding gas, and the activated carbon net 82 can adsorb carbon monoxide in the welding gas, reducing the high concentration of carbon monoxide in the air, which in turn affects the health of the staff. When it is necessary to clean or replace the fine filter 81 and the activated carbon net 82, the staff can pull the second handle 17, and the second handle 17 can drive the purification drawer 7 to move outward. At the same time, the semicircular block 10 can be squeezed by the purification box 5 to push the spring 9 to compress, so that the staff can quickly pull out the purification drawer 7 and clean or replace the fine filter 81 and the activated carbon net 82.
