Description

Technical Field

[0001] The utility model relates to the technical field of ventilation ducts, in particular to a ventilation duct connection structure for electromechanical engineering. Background Art

[0002] Ventilation ducts are metal or non-metallic ducts used for ventilation in air-conditioning projects in industrial or civil buildings. They are a kind of municipal infrastructure designed to allow air circulation and reduce the concentration of harmful gases. Ventilation ducts are generally divided into three types of materials: galvanized ventilation ducts, fiberglass ventilation ducts and composite ventilation ducts. The most common are galvanized ventilation ducts. A complete ventilation system is assembled by connecting multiple ventilation ducts. At present, most ventilation ducts are connected together using bolts.

[0003] Current ventilation ducts are usually connected by bolts when in use. When encountering vibration, the bolted joints are easily broken. In addition, the sealing effect is poor when connected only by bolts. Therefore, a ventilation duct connection structure for electromechanical engineering is needed. Utility Model Content
