Description

Technical Field

[0001] The utility model relates to the technical field of fresh air ducts, in particular to a fresh air duct structure. Background Art

[0002] The fresh air system is based on using special equipment to deliver fresh air to the room on one side of a closed room, and then exhaust it to the outside from the other side by special equipment, forming a "fresh air flow field" in the room, thereby meeting the needs of indoor fresh air ventilation. When fresh air is delivered, pipes need to be arranged indoors. During the use of the pipes, dust, bacteria, etc. will accumulate inside the pipes over time, so they need to be cleaned. Traditional pipes are integral cylindrical pipes, and the inside is not easy to clean and thoroughly, which will affect health. For this reason, we propose a fresh air pipe structure.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1 , Figure 2 A fresh air duct structure comprises a first semicircular tube 1 and a second semicircular tube 2, wherein the two straight sides of the first semicircular tube 1 are fixed with a first boss 3, and the two straight sides of the second semicircular tube 2 are fixed with a second boss 4, and the first boss 3 and the second boss 4 are detachably connected via a locking assembly 7, wherein the locking assembly 7 is provided with a plurality of groups, and the duct consists of the first semicircular tube 1 and the second semicircular tube 2, and is detachably connected via the locking assembly 7, so as to facilitate the cleaning of the interior of the first semicircular tube 1 and the second semicircular tube 2 after being unfolded, thereby avoiding the problem of a large number of bacteria generated due to the accumulation of dust inside and being unable to be cleaned.

[0022] Reference Figure 2 Both ends of the first semicircular tube 1 are fixed with first connecting blocks 5 with bolt holes, and both ends of the second semicircular tube 2 are fixed with second connecting blocks 6 with bolt holes. The bolt holes on the first connecting block 5 and the bolt holes on the second connecting block 6 can be used to connect with other pipelines, which is convenient for disassembly and assembly.

[0023] Reference Figure 2 , Figure 4 , Figure 5 A first semicircular sealing groove 10 is provided at both ends of the first semicircular tube 1, and a second semicircular sealing groove 11 is provided at both ends of the second semicircular tube 2. The first semicircular sealing groove 10 and the second semicircular sealing groove 11 are sleeved with the same sealing ring 8, which helps to improve the airtightness of the connection with other pipelines and avoid leakage.

[0024] Reference Figure 3 When the locking cam 72 is in the state of being moved forward, the locking cam 71 can be turned to the left of the locking cam 74, so that the locking cam 72 can be turned back to the locking cam 74. When the locking cam 72 is in the state of being moved forward, the locking cam 71 can be turned to the right of the locking cam 74.

[0025] Reference Figure 3 , Figure 4 , Figure 5 A first strip sealing groove 12 is provided on the end face of the first boss 3, and a second strip sealing groove 13 is provided on the end face of the second boss 4.
