Abstract
The utility model discloses an air port connecting device for a centrifugal fan. The air port connecting device consists of a first connecting flange and a second connecting flange, wherein the first connecting flange and a first hoop are integrally connected through a bolt; the second connecting flange is integrally connected with a second hoop by the bolt; one end of a soft rubber sheet is clamped between the first connecting flange and the first hoop while the other end thereof is clamped between the second connecting flange and the second hoop; and two ends of a supporting plate are respectively connected to the first hoop and the second hoop by the bolts. The air port connecting device disclosed by the utility model improves the rigidity, and prevents the soft rubber sheet from being damaged during conveying and mounting; meanwhile, the mounting error can be automatically compensated during mounting; the stretching force can be transformed from the soft rubber sheet to the supporting plate during using, and the soft rubber sheet is prevented from being damaged during operating the device.
Description
Technical field:
The utility model relates to the ventilator field, more specifically to a kind of air port connection set of centrifugal blower.
Background technique:
The exhaust outlet of centrifugal blower is to link to each other through the air port connection set with ventilation duct; Existing air port connection set connects exhaust outlet and ventilation duct road junction through two flanges; Be fixed with soft rubber between two flange plate; This can adjust some alignment errors that occur when installing when ventilation duct is installed, simultaneously, can solve the phenomenon of expanding with heat and contract with cold that produces when ventilating.Its deficiency is: owing to only be fixed with soft rubber between two flanges, this can't guarantee the intact of connection set when installing and transporting; Simultaneously, when using after the installation, do not support; Wind lets soft rubber agitate stretching through meeting, soft rubber is worn out break.
The model utility content:
The purpose of the utility model is exactly the deficiency to existing technology; And a kind of air port connection set of centrifugal blower is provided, it has strengthened the rigidity of whole air port connection set, has guaranteed can soft rubber not to be damaged when the air port connection set transports and installs; Simultaneously; Can remedy alignment error automatically when mounted, in use tensile force transferred on the dunnage from soft rubber, soft rubber can not damage during the running of assurance equipment.
The technological solution of the utility model is following:
A kind of air port connection set of centrifugal blower comprises first adpting flange and second adpting flange, and first adpting flange and first anchor ear link together through bolt, and second adpting flange and second anchor ear link together through bolt; Soft rubber one end is clamped between first adpting flange and first anchor ear, and the other end is clamped between second adpting flange and second anchor ear, and two ends of dunnage are connected on first anchor ear and second anchor ear through bolt respectively.
Said bolt is made up of screw rod and nut, and the dunnage sleeve forms hinged on screw rod.
Said nut compresses dunnage formation and tightens up.
Said first anchor ear and second anchor ear are connected with two dunnages through bolt, and two dunnages are that the diagonal angle, center distributes with the center of first adpting flange.
The beneficial effect of the utility model is:
It has strengthened the rigidity of whole air port connection set; Guaranteed can soft rubber not damaged when the air port connection set transports and installs; Simultaneously; Can remedy alignment error automatically when mounted, in use tensile force transferred on the dunnage from soft rubber, soft rubber can not damage during the running of assurance equipment.
Description of drawings:
Fig. 1 is the perspective view of the utility model;
Fig. 2 is the linkage structure schematic representation between second adpting flange, second anchor ear, soft rubber and the dunnage of the utility model;
Fig. 3 is the sectional view of the utility model.
Among the figure: 1, first adpting flange; 2, second adpting flange; 3, first anchor ear; 4, second anchor ear; 5, soft rubber; 6, dunnage.
Embodiment:
Embodiment: of Fig. 1 to Fig. 3; A kind of air port connection set of centrifugal blower; Comprise that first adpting flange 1 and second adpting flange, 2, the first adpting flanges 1 and first anchor ear 3 link together through bolt, second adpting flange 2 and second anchor ear 4 link together through bolt; Soft rubber 5 one ends are clamped between first adpting flange 1 and first anchor ear 3, and the other end is clamped between second adpting flange 2 and second anchor ear 4, and two ends of dunnage 6 are connected on first anchor ear 3 and second anchor ear 4 through bolt respectively.
Bolt is made up of screw rod and nut, and dunnage 6 sleeves form hinged on screw rod.
Nut compresses dunnage 6 formation and tightens up.
It is that the diagonal angle, center distributes with the center of first adpting flange 1 that first anchor ear 3 and second anchor ear 4 are connected with 6, two dunnages 6 of two dunnages through bolt.
Working principle: with the air port connection set with when ventilation duct is connected, unclamp the bolt that connects dunnage 6, make that dunnage 6 can rotation angle; Can tricklely adjust when mounted, guarantee that the air port connection set is connected with ventilation duct is complete, connect the bolt that will connect dunnage 6 after accomplishing and tighten; So not only increased the rigidity of whole air port connection set, guaranteed that the air port connection set transports Shi Buhui soft rubber 5 is damaged, simultaneously; Can remedy alignment error automatically when mounted, feasible normally connection, simultaneously; In use wind passes through from ventilation duct, and the soft rubber 5 of air port connection set can be stretched in the agitating of wind, owing to be connected with dunnage 6; Make tensile force transfer on the dunnage 6 from soft rubber 5 like this, soft rubber 5 can not damage during the running of assurance equipment.
