[0017] In order to make the purpose, technical solutions, and advantages of the present utility model clearer, the preferred embodiments of the present utility model will be described in detail below with reference to the drawings for the convenience of those skilled in the art to understand.

[0018] The utility model discloses an air duct connection structure for an airport. The air duct connection structure for an airport mainly includes an air duct 1, a sealing component 3, and a connecting component 4. The air duct 1 is connected to an adjacent air duct 1 through the sealing component 3. The sealing component 3 includes an annular rubber block 301, an elastic sealing ring 302, a suede magic tape 303, and a hook magic tape 304. An annular rubber block 301 is provided at one end of the air duct 1. An annular positioning groove 3011 with a circular cross-section is formed on the inner wall of the annular rubber block 301. An elastic sealing ring 302 that is engaged with the annular positioning groove 3011 on the adjacent air duct 1 is provided on the outer wall of the other end of the air duct 1. A hook magic tape 304 is provided on the outer surface of the air duct 1, and the hook magic tape 304 is close to the elastic sealing ring 302. A suede magic tape 303 that is adhesively bonded to the hook magic tape 304 is provided on the inner wall of the annular rubber block 301. The suede magic tape 303 is close to the port position of the annular rubber block 301. The end of the air duct 1 extends into the interior of the adjacent air duct 1 and is connected to each other through the connecting component 4. The connecting component 4 is distributed in a circumferential array along the air duct 1. The connecting component 4 includes a flexible belt 401, a male head 402, a female head 403, and an elastic plug 404. A plurality of flexible belts 401 are uniformly arranged on the outer wall of the end of the air duct 1 along the circumferential direction. Straight notch openings 4021 for winding the flexible belt 401 are formed on both the male head 402 and the female head 403. A slot 4031 is formed inside the female head 403. Two elastic plugs 404 that are engaged with the slot 4031 are provided at the end of the male head 402. Rectangular through holes 4032 that are communicated with the slot 4031 are formed on both sides of the female head 403.

[0019] When connecting the two ends of the air duct, the ground crew inserts one end of the air duct 1 into the interior of the other section of the air duct 1, so that the elastic sealing ring 302 on the outer wall of the air duct 1 is embedded into the annular positioning groove 3011 on the annular rubber block 301 at the end of the other section of the air duct 1, and they form a sealed connection under the action of air pressure, ensuring the sealing performance at the connection of the air duct and effectively preventing air leakage of the air duct 1, thereby reducing energy loss and improving the operating efficiency of the air conditioning system. Then, the ground crew presses the annular rubber block 301 along the circumferential direction of the air duct 1, so that the suede magic tape 303 on the inner wall of the annular rubber block 301 is adhesively bonded to the hook magic tape 304 on the outer wall of the other section of the air duct 1, ensuring that the air duct 1 will not slip off under vibration or external force. Next, the ground crew inserts the elastic plug 404 on the male head 402 into the slot 4031 on the female head 403 to connect the two sections of the air duct 1, avoiding the problem of the air duct slipping off under the action of external force dragging, and further improving the stability of the air duct connection. When disassembling, the finger presses the elastic plug 404 through the rectangular through hole 4032, and the male head 402 and the female head 403 can be disassembled, and the operation is simple and fast.

[0020] The distance between the elastic sealing ring 302 and the end of the air duct 1 is not less than 5 cm. During operation, under the action of gas pressure at the connection between the end of the air duct 1 and the adjacent air duct 1, the outer wall of this air duct 1 is closely attached to the inner wall of the adjacent air duct 1, forming a sealed connection, which is beneficial to improving the sealing performance of the connection of the air duct 1 and effectively preventing gas leakage.

[0021] Operation process:

[0022] When connecting the air ducts at both ends, the ground crew inserts one end of the air duct 1 into the interior of another section of the air duct 1, so that the elastic sealing ring 302 on the outer wall of the air duct 1 is embedded in the annular positioning groove 3011 on the annular rubber block 301 at the end of another section of the air duct 1, and they form a sealed connection with each other under the action of air pressure, ensuring the sealing performance at the connection of the air ducts and effectively preventing air leakage of the air duct 1, thereby reducing energy consumption and improving the operation efficiency of the air conditioning system. Then, the ground crew presses the annular rubber block 301 along the circumferential direction of the air duct 1, so that the flocked magic tape 303 on the inner wall of the annular rubber block 301 adheres to the hook magic tape 304 on the outer wall of another section of the air duct 1, ensuring that the air duct 1 will not slip off under the action of vibration or external force. Next, the ground crew inserts the elastic plug 404 on the male head 402 into the slot 4031 on the female head 403 to connect the two sections of the air duct 1, avoiding the problem of the air duct slipping off under the action of external force dragging, and further improving the stability of the connection of the air duct. When disassembling, the finger presses the elastic plug 404 through the rectangular through hole 4032 to disassemble the male head 402 from the female head 403, and the operation is simple and fast.
