Description

Technical Field

[0001] The utility model relates to the field of pipeline connection, in particular to a composite reinforced flange connection device used for connecting air ducts. Background Art

[0002] During the installation of air ducts, if long-distance connection installation or connection installation at a bend is required, flange connectors are needed to connect two sections of air ducts. At present, in order to facilitate processing and connection installation, flange connectors between air ducts are preferably made of PVC material. Compared with traditional metal flange connectors, they are more plastic and sealed, and are lighter overall, which can greatly improve the convenience of the connection and installation process. However, flange connectors made of PVC material have the problem of insufficient strength. When used for a long time or when the air duct vibrates violently, they are prone to deformation, loosening and other problems. Utility Model Content

[0003] The utility model aims to provide a composite reinforced flange connection device for connecting air ducts, which solves the problems of low strength and easy deformation of the above-mentioned PVC material flange connection parts.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a composite reinforced flange connection device for connecting air ducts, comprising a first connecting head and a second connecting head that can be detachably connected, the first connecting head and the second connecting head are both provided with a plug-in groove for plugging and fixing with the air duct, and a U-shaped reinforced connecting piece is provided in the plug-in groove; the outer sides of the first connecting head and the second connecting head are both provided with fixing buckles, and the outer sides of the first connecting head and the second connecting head are fixedly connected by setting a fixing clip.

[0005] Specifically, the first connector and the second connector are made of PVC material, and the U-shaped reinforcing connector is made of metal material.

[0006] Specifically, a sealing connection pad is arranged between the first connection head and the second connection head.

[0007] Specifically, an anti-slip portion is provided on the inner side of the U-shaped reinforcing connector, and the anti-slip portion is in an inclined sawtooth shape inclined toward the bottom of the U-shaped reinforcing connector.

[0008] Specifically, the plug-in slots of the first connector and the second connector are both provided with a snap-in groove, and the U-shaped reinforcing connector is fixedly snap-into the snap-in groove.

[0009] The beneficial effect of the utility model is that by arranging a U-shaped reinforcing connector in the plug-in groove of the air duct connection, the flange connection device of the PVC material is kept light while having higher strength, effectively avoiding the problem of deformation and loosening after long-term use; and the anti-slip part arranged in the U-shaped reinforcing connector can further improve the stability of the air duct connection.
