A kind of Miniature wind mouth structure
Technical field
The present invention relates to the technical field of air cleaning facility ventilating opening structure, be specially a kind of Miniature wind mouth structure.
Background technology
The inside in small-sized air port is provided with filter, between filter and casing, need sealing, its hermetically-sealed construction Structure of need supporting, fastening, existing small-sized air port, it is by completing at cabinet wall welding knife-edge flange, knife-edge flange needs and casing passes through separately respectively bender bending and molding, the inner side of knife-edge flange is rib bar, top is flange face, outside is for being welded to connect face, bottom is also flange face, upper flange face is fastenedly connected sealing supporting structure, lower flange face is fastenedly connected diffuser plate, due to knife-edge flange, after the independent machine-shaping of casing, welding is located by connecting, the accuracy of the appearance and size of its very difficult guarantee equipment, affect the formed precision of equipment, and the sealing of its commissure can not ensure.
Summary of the invention
For the problems referred to above, the invention provides a kind of Miniature wind mouth structure, it makes simple, good seal performance, and guaranteed the accuracy of appearance and size, guarantee the formed precision of equipment.
A kind of Miniature wind mouth structure, its technical scheme is such: it comprises casing, filter, sealing supporting structure, diffuser plate, described filter is supported on described sealing supporting structure, it is characterized in that: the At The Height that is positioned at described sealing supporting structure of described casing convexes into horizontal upper part flange, longitudinally rib bar, described horizontal upper part flange, longitudinally rib bar is all two-layer structure, the external wall of upper portion ffp filter of described casing connects the upper strata of described horizontal upper part flange, the upper strata of described horizontal upper part flange, the longitudinally internal layer of rib bar, the longitudinally skin of rib bar, between the lower floor of horizontal upper part flange, arc transition connects continuously successively, between the bottom outer wall of the lower floor of described horizontal upper part flange and casing, be connected continuously, the bottom outer wall of described casing connects horizontal lower outer flange continuously.
It is further characterized in that: described sealing supporting structure is bolted connection described horizontal upper part flange;
Described diffuser plate is bolted connection described horizontal lower outer flange.
Adopt after structure of the present invention, by steel plate by the one-body molded external wall of upper portion that forms casing, horizontal upper part flange, the longitudinal bottom outer wall of rib bar, casing, without forming sealing by extra soldered, and horizontal upper part flange, longitudinal rib bar are all two-layer structure, it makes simple, good seal performance, and guaranteed the accuracy of appearance and size, guarantee the formed precision of equipment.
