Description

Technical Field

[0001] The present application relates to the technical field of ventilation ducts, and in particular to a ventilation duct connection structure. Background Art

[0002] Ventilation ducts, also known as air ducts, are metal or non-metallic pipes used in ventilation and air-conditioning projects in industrial and civil buildings. They are mainly used to achieve the circulation and exchange of air inside the building, thereby keeping the indoor air fresh and comfortable.

[0003] For example, the Chinese utility model patent with publication number "CN216813270U" discloses a combined ventilation duct connection structure. The utility model provides connecting plates on the outer sides of the ventilation ducts, and respectively provides connecting heads and connecting grooves on the connecting plates of adjacent ventilation ducts. When the ventilation ducts need to be assembled together, the connecting plates at the ends of the two ventilation ducts are aligned, the connecting head on one end connecting plate is slid into the connecting groove on the other connecting plate, and the position of the connecting head is preliminarily fixed by an elastic sheet, thereby realizing rapid connection of the two ventilation ducts, making the docking of the ventilation ducts more accurate and the assembly efficiency higher; a connecting rod is rotatably provided on one of the connecting plates, and a fixed column is provided on the other connecting plate. After the docking is completed, the connecting rod is rotated so that one side of the connecting rod is close to the fixed column, and the positioning rod on the sliding connecting rod is matched with the fixed column. The position of the positioning rod is limited by a reset spring, thereby realizing a fixed connection between the connecting rod and the fixed column.

[0004] The aforementioned patent allows the ventilation duct to be connected, but the device is difficult to filter the circulating air when in use, and it is difficult to effectively remove dust and other harmful substances in the air. These pollutants are transported into the room with the air flow, resulting in a decrease in indoor air quality. Utility Model Content

Through the connecting mechanism 2, the connecting plate 204 can be pulled by pulling the pull rod 206 to drive the No. 1 limit block 205 to rise while the telescopic rod 203 and the No. 1 spring 207 are retracted, and then the two duct bodies 1 are aligned to make the connecting block 202 slide Into the inner wall surface of the connecting pipe 201, loosen the pull rod 206, and the No. 1 spring 207 rebounds to drive the telescopic rod 203 and the No. 1 limit block 205 to reset, so that the No. 1 limit block 205 slides into the inner wall surface of the connecting block 202 to limit the connecting block 202 and thus connect the two pipe bodies 1. Through the filtering mechanism 3, the filter plate 301 can filter the circulating air during use to prevent dust from entering the room. When the filter plate 301 needs to be cleaned or replaced, pull the sliding rod 305 to disengage the No. 2 limit block 304 from the fixed block 303, and then pull the fixed block 303 to pull the fixed block 303 out of the device to facilitate cleaning or replacement of the filter plate 301.

[0039] Working principle: When using the device, you should first pull the pull rod 206 to make the connecting plate 204 drive the No. 1 limit block 205 to rise while the telescopic rod 203 and the No. 1 spring 207 retract. Then, align the two pipe bodies 1 so that the connecting block 202 slides into the inner wall surface of the connecting pipe 201, release the pull rod 206, and the No. 1 spring 207 rebounds to drive the telescopic rod 203 and the No. 1 limit block 205 to reset so that the No. 1 limit block 205 slides into the inner wall surface of the connecting block 202 to limit the connecting block 202 and thus connect the two pipe bodies 1. When the ventilation duct is in use, the filter plate 301 can filter the circulating air to prevent dust from entering the room.
