Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-6 In the embodiment of the present invention, a high-efficiency air outlet comprises an air outlet frame 1 installed at the opening of the wind box 17. The air outlet frame 1 is provided with two and the two air outlet frames 1 are rotatably connected. The air outlet frame 1 is a rectangular structure. The middle part of the air outlet frame 1 is a rectangular through-hole structure. A mesh plate or a blade is installed at the rectangular through-hole position of the air outlet frame 1. The air outlet frames 1 on both sides are directly rotatably connected through the rotating shaft 2. The rotating shaft 2 is rotatably connected with a plywood 3 on both sides. The plywood 3 on both sides is respectively fixedly connected to the frame of the air outlet frame 1 on both sides. Tenons 5 and rivet holes 6 are respectively provided at both ends of the air outlet frame 1. Adjacent air outlet frames 1 are connected by the tenons 5 and rivet holes 6 is connected in a mating manner. In this embodiment, the size of the air outlet on the bellows 17 is 630 mm × 250 mm, the bottom surface of the bellows 17 is 1160 mm × 2320 mm, the air supply outlet is opened on the bottom surface, the thickness of the cold-rolled steel plate used to make the bellows 17 is above 1.2 mm, the air outlet frame 1 is installed at the air outlet of the bellows 17, the frame of the air outlet frame 1 is pressed against the inner wall of the bellows 17, and the outer side of the air outlet frame 1 is movably connected to the top block 4, the top block 4 and the frame of the air outlet frame 1 are slidably connected, and a compression spring is provided between the top block 4 and the frame of the air outlet frame 1, and the end of the top block 4 is curved.

[0026] The lower end of the air vent frame 1 is provided with a connecting portion for fixing to the inner wall of the bellows 17, and the connecting portion includes a top plate 12 slidingly connected to the air vent frame 1, and a cavity 11 is provided in the frame of the air vent frame 1. The top plate 12 is slidably connected to the cavity 11. The air vent frame 1 is threaded with a bolt 7 for adjusting the relative position of the top plate 12 and the air vent frame 1. A threaded connection seat 14 is provided on the side of the top plate 12 close to the bolt 7, and the end of the bolt 7 is freely rotatably connected to the threaded connection seat 14. An avoidance hole 18 for avoiding the bolt 7 is provided on the inner wall of the bellows 17. A piston tube 15 is provided on the air vent frame 1, and one end of the piston tube 15 extends to the outside of the air vent frame 1 and is connected to a suction cup 10. The other end of the piston tube 15 is inserted into the piston column 13, and the end of the piston column 13 away from the suction cup 10 is fixedly connected to the top plate 12. A mounting plate 8 is slidably connected to the air outlet frame 1 , a ball bearing 9 is movably connected to the side of the mounting plate 8 away from the top plate 12 , and a spring rod 16 is provided between the side of the mounting plate 8 close to the top plate 12 and the top plate 12 .

[0027] When the utility model is in use, the shaft 2 is used as the central axis to rotate the air vent frames 1 on both sides of the shaft, so that the shaft 2 drives the air vent frames 1 on both sides that are not fully unfolded to enter the bellows 17, and then the shaft 2 is slowly rotated to gradually adjust the angle of the shaft 2 and make the air vent frames 1 on both sides horizontal. Under the action of gravity, the air vent frames 1 on both sides of the shaft 2 are gradually unfolded until they are flattened to the inside of the bellows 17, which is better for the layout of workshop pipelines, lighting, and fire protection. The layout space is saved by merging high-efficiency air vents, and the layout in the workshop is beautiful. On the one hand, multiple existing small air vents can be integrated into a large air vent, and on the other hand, the two air vent frames 1 and the bellows 17 can be quickly installed. When the unfolded air vent frame 1 is flattened inside the bellows 17, the top block 4 will be tightly pressed against the inner wall of the bellows 17 under the action of elastic force, and the elastic force is used to achieve clamping to improve the stability of the air vent frame 1.

[0028] When the two tuyere frames 1 are spread out flat, the rolling characteristics of the ball 9 are used to move the tuyere frame 1 on the horizontal plane to adjust the position of the tuyere frame 1, so that the tuyere frame 1 can be accurately installed in the bellows 17. Then, the bolt 7 is rotated to drive the top plate 12 downward through the threaded transmission characteristics between the bolt 7 and the tuyere frame 1. While the spring rod 16 is compressed and contracted, the suction cup 10 gradually discharges the air in the suction cup 10. Then, the bolt 7 is rotated in the opposite direction to allow the piston column 13 to move upward in the piston tube 15. The negative pressure is used to allow the suction cup 10 to be tightly adsorbed on the inner wall of the bellows 17, thereby improving the stability of the position of the tuyere frame 1 in the bellows 17. After the artificially applied force is removed, the bolt 7 can use the self-locking characteristic to keep relatively still with the tuyere frame 1.
