Description
Technical field
The utility model relates to air-conditioning, refers in particular to a kind of ajutage of central air-conditioning.
Background technology
Air-conditioning refers to uses artificial means, the parameter such as temperature, humidity, cleanliness factor, speed of building/structures environment air is carried out to the process of regulation and control.It is made up of cold and heat source system and air handling system.The principle of vaporizing liquid refrigeration is adopted to provide institute's chilling requirement, in order to offset the refrigeration duty of indoor environment for air handling system; Heating provides the heat of offsetting indoor environment thermic load for air handling system.When airduct is oversize, can produces built on the sand and rock, tilt, tradition be by increasing support bar in centre; This mode not only has impact to sealing, and processing is installed complicated, particularly to the cleaning of inside, usually clears up with small machine people, and middle support bar can block, and cannot realize effective cleaning.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of structure of central air-conditioning is simple, high, the indeformable ajutage of good airproof performance, intensity.
For achieving the above object, technical scheme provided by the utility model is: a kind of ajutage of central air-conditioning, described ajutage tube wall is by two-layer color steel and be positioned at the middle heat-insulation layer composite molding of color steel, after compound, sheet material cuts the V-arrangement folding groove of 90 degree, main body is converted into after covering glue in folding groove, be converted into the corner after main body and be provided with fixed angles pin, fixed angles pin is by the corner of rivet in main body wall, described fixed angles pin adopts sheet metal bent 90 degree to form main body, two connection panels of fixed angles pin are respectively provided with several riveted holes, the connection panel of fixed angles pin is provided with protruding ribs.
Described folding slot is on the color steel and heat-insulation layer of tube wall internal layer.
The utility model has the advantage of: by reinforcing at right angle fixed angles pin, fix at airduct outer wall rivet during installation, considerably increase firmness, and install very convenient, in addition, fixed angles instep plate extrudes the raised rib strengthened, increase angle pin intensity, if be fixed on outer wall, then the projection on iron pin is preferably protruding laterally, what make at present due to client is fixing with on inwall, therefore is inwardly protruding.The structure of this programme is simple, good airproof performance, intensity are high, indeformable.
Accompanying drawing explanation
Fig. 1 is V groove schematic diagram of the present utility model.
Fig. 2 is overall structure schematic diagram of the present utility model.
Fig. 3 is fixed angles pin schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1 to accompanying drawing 3, the ajutage tube wall of central air-conditioning described in the present embodiment is by two-layer color steel 1 and be positioned at middle heat-insulation layer 2 composite molding of color steel, after compound, sheet material cuts the V-arrangement folding groove 3 of 90 degree, roll on groove 3 color steel 1 that is positioned at tube wall internal layer and heat-insulation layer 2; Main body is converted into after covering glue in folding groove 3, be converted into the corner after main body and be provided with fixed angles pin 4, fixed angles pin 4 is by the corner of rivet in main body wall, described fixed angles pin 4 adopts sheet metal bent 90 degree to form main body, two connection panels of fixed angles pin 4 are respectively provided with several riveted holes 5, and the connection panel of fixed angles pin 4 is provided with protruding ribs 6.By reinforcing at right angle fixed angles pin, fix at airduct outer wall rivet during installation, considerably increase firmness, and install very convenient, in addition, fixed angles instep plate extrudes the raised rib strengthened, increase angle pin intensity, if be fixed on outer wall, then the projection on iron pin is preferably protruding laterally, what make at present due to client is fixing with on inwall, therefore is inwardly protruding.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
