Conventional central air conditioner cold water unit is generally open type design, user, meets after functional requirement, equipment acoustic noise and outward appearance is proposed to higher demand, adopts gradually trend of enclosed construction design.Central air-conditioning product exists model specification many, and same model volume production is few, and structural design versatility is poor, shell sizes is large, the heavier feature of panel, it is uneconomical that obviously panel adopts die sinking design, thereby need seek to process simple, easy for installation, fixed, practical panel construction mode.
Utility model content
The purpose of this utility model is to provide that a kind of to design succinct, overall appearance, installation convenient, fixing reliable and be easy to the central air-conditioning panel of processing and implementation and the syndeton of frame, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
The syndeton of a kind of central air-conditioning panel and frame, comprise sheet metal panel, frame and bolt, described sheet metal panel punching processes by the secondary bending of colding pressing, in sheet metal panel upper end, flanging offers screw hanging hole, on the sheet metal panel of screw hanging hole right opposite, offer fabrication hole, the frame upper end coordinating with sheet metal panel is provided with riveting nut, on riveting nut, be screwed into the machine screw identical with screw hanging hole, infolding base, described sheet metal panel lower end is also provided with riveting nut, described frame lower end is welded with the support member of accepting sheet metal panel, on support member, offer lower fabrication hole, described bolt is screwed in riveting nut by lower fabrication hole.
As further program of the utility model: described screw hanging hole is provided with three, and described support member is provided with two, and described upper fabrication hole is furnished with plastics stopple.
As the utility model scheme further: described sheet metal panel is integral panels or split panel, and the trimming of sheet metal panel lower end forms outer splayed configuration panel.
Compared with prior art, the beneficial effects of the utility model are: stopple covers fabrication hole, and bottom bolt is hidden in sight line naturally, realize positively without exposed screws, beautifying appearance effect, and global design simplicity generosity, machining are simple, easy for installation.
