Description

Technical Field

[0001] The utility model relates to the technical field of ventilation pipe equipment, in particular to a reinforced outdoor windproof stainless steel ventilation pipe. Background Art

[0002] Ventilation ducts are hollow pipes used for ventilation, mostly round or square. Ventilation ducts generally include: purification system return air ducts, central air conditioning ventilation ducts, industrial supply and exhaust ventilation ducts, environmental protection system suction and exhaust ducts, mining gas extraction pipes, mining rubberized cloth air ducts; fire smoke ventilation ducts, etc. Among them, outdoor ventilation ducts are installed outdoors all year round and are easily damaged by external wind damage or external force collisions and other damaging impacts. Therefore, users have higher requirements for the strength of outdoor ventilation ducts.

[0003] Application number CN202120631720.3 discloses a reinforced outdoor windproof ventilation duct, including a pipe body made of rectangular stainless steel with a rectangular tube cavity inside the pipe body. The pipe body has an inner and outer double-layer structure, and columnar reinforcing ribs are welded between the inner outer wall of the pipe body and the outer inner wall of the pipe body. A reinforcement frame is clamped on the outer surface of the pipe body, and a plurality of fastening bolts are tightened in threaded holes on the outer surface of the reinforcement frame to fix the reinforcement frame to the outer surface of the pipe body. The bottom end surface of the fastening bolts engages with the threaded concave holes recessed on the outer surface of the pipe body. The utility model is easy to adjust and has a high degree of fit. The outer wall of the pipe body can be reinforced according to user needs to achieve the purpose of windproof and impact resistance.

[0004] The reinforced outdoor windproof ventilation duct disclosed in the above document has the following defects: the structure firmly connects the joints of the two pipes through a reinforcement frame and bolts. When the two pipes are hit by strong winds, if there is no fixing component between the reinforcement frame and the pipes, the pipes may loosen and fall off from the reinforcement frame.

[0005] It can be seen from this that the existing outdoor windproof ventilation pipe does not have the function of reinforcing the connection between the connector and the pipe. It is necessary to improve the existing deficiencies and provide a function that can reinforce the connection between the connector and the pipe. Utility Model Content
