[0023] A heat-insulating fire-resistant air duct includes: a ventilation duct 1 and a connecting structure 2. The outer side of the inner pipe 101 in the ventilation duct 1 is welded to the triangular groove 102. The triangular groove 102 is filled with heat-insulating sponge 103. The outer side of the triangular groove 102 is welded to the lower end of the middle pipe 104. The outer side of the front end of the ventilation duct 1 is welded to the inner side of the connecting structure 2. The inner side of the first connecting piece 201 in the connecting structure 2 is welded to the upper end of the inner groove 203. The lower end of the inner groove 203 is welded to the outer side of the second connecting piece 206.

[0024] Furthermore, the outer side of the internal pipe 101 in the ventilation pipe 1 is welded to the lower end of the triangular groove 102. The triangular groove 102 is filled with heat-insulating sponge 103. The triangular groove 102 on the outer side of the internal pipe 101 is used to divide the heat-insulating sponge 103 so that the heat-insulating sponge 103 will not burn together when it is burned.

[0025] Furthermore, the insulating sponge 103 fills the internal void of the triangular groove 102, and the outer side of the triangular groove 102 is welded to the lower end of the middle pipe 104. The middle pipe 104 is used to protect the triangular groove 102 and the insulating sponge 103.

[0026] Furthermore, the outer side of the intermediate pipe 104 is welded to the lower end of the outer support 105, and the upper end of the outer support 105 is welded to the inner side of the outer shell 106. The outer support 105 on the outside of the intermediate pipe 104 is used to protect the intermediate pipe 104 from easily breaking when it is impacted. The outer shell 106 wraps around the outer support 105 to protect the outer support 105 from easily being damaged when it is impacted.

[0027] Furthermore, the inner side of the second connecting piece 206 in the connecting structure 2 is welded to the outer ring of the outer shell 106 in the ventilation pipe 1, the inner side of the first connecting piece 201 is hollow to form a first threaded hole 202, the second connecting piece 206 is used to weld to the lower end of the inner groove 203, and the first threaded hole 202 is used to connect the first connecting piece 201 and the third connecting piece 207.

[0028] Furthermore, the inner side of the first connecting piece 201 is welded to the outer side of the inner groove 203. The inner groove 203 is hollow inside, and the outer ring of the inner groove 203 is hollow to form a second threaded hole 204. The inner groove 203 is used to insert the insert 208, and the second threaded hole 204 is used to connect the inner groove 203 and the insert 208 together and use the threaded groove 205 to connect the bolts.

[0029] Furthermore, the lower end of the second threaded hole 204 is welded to the threaded groove 205, the lower end of the inner groove 203 is welded to the periphery of the second connecting piece 206, and the first connecting piece 201 and the third connecting piece 207 are connected by inserting a plug 208. The third connecting piece 207 is used to insert the pipe at the other end into the inner groove 203 inside the first connecting piece 201 using the plug 208.

[0030] Working principle: When in use, insert the plug 208 into the inner groove 203, aligning the first threaded hole 202 in the first connecting piece 201 with the first threaded hole 202 in the third connecting piece 207. Then, insert a bolt into the first threaded hole 202 to connect the first connecting piece 201 and the third connecting piece 207. Finally, insert a bolt into the second threaded hole 204 to connect the inner groove 203 with the plug 208. When hot air is transmitted inside the pipe, the heat-insulating sponge 103 inside the triangular groove 102 insulates the hot air. When the air passes through the pipe connection, the plug 208 blocks the gap leading to the outside of the pipe, preventing the air from leaking out from the pipe connection.
