The invention will be further elucidated with reference to the accompanying figures 1 to 9:

the first embodiment is as follows:

as shown in fig. 1 and 2, the tubular-to-tubular-. The first air duct 1 comprises an air duct box body 11, 3L-shaped angle steel pieces 13 with 4 bolt through holes and 1L-shaped angle steel piece 12 with 2 bending teeth. The second ductwork 2 comprises a ductwork box 21 containing 3L-angle pieces 23 for mounting bolts and 1L-angle piece 22 with 2 kidney-shaped holes. First tuber pipe 1 all is equipped with four flanges that turn over to the pipe wall outside towards the port department of second tuber pipe 2 and the port department of second tuber pipe 2 towards first tuber pipe 1, and all flanges are rectangular long strip along the horizontal square, and flange thickness is the same with the tuber pipe wall, and flange length is 30mm in this embodiment. The L-shaped angle steel piece is fixed on the wall of the air pipe in a rivet connection mode, the other end face of the L-shaped angle steel piece is tightly attached to the flange, and the thickness of the L-shaped angle steel piece is 3 mm.

As shown in figures 5 and 7, the bending teeth of the L-shaped angle steel part form an acute angle with the horizontal, the angle is 60 degrees, the thickness of the bending teeth is the same as that of the L-shaped angle steel part, and the width of the bending teeth is 10 mm. The machining of the bending teeth is firstly to cut the L-shaped angle steel part according to the length of the bending teeth and bend the L-shaped angle steel part through a bending machine, and the machining is convenient and simple. Waist shape through-hole is the same with the tooth width of bending, and its length will be 5mm so that the smooth of bending the tooth inserts, the joint strip that is the rectangle is all installed to the flange downside of first tuber pipe and second tuber pipe flange upside, and adhesive tape thickness is 2.5mm in this embodiment. The air pipe box body integral installation idea is that first an air pipe and a second air pipe are staggered, bending teeth of the first air pipe are vertically inserted into a waist-shaped hole, then the bending teeth are pushed towards the direction of a wall body, other three side hole sites are aligned, and finally, the three side bolts of the air pipe box body are fixedly connected. The principle of the air pipe box body is that three sides of the air pipe box body are fixed through bolts, the upper surface of a bending tooth close to the wall side is in contact with the lower side of a waist-shaped hole, the bending tooth generates small deformation and friction force to extrude the waist-shaped hole, and the attaching and sealing effects are achieved.
