STATEMENT OF FEDERALLY SPONSORED.
Background technology：
Blower fan fire resisting damper is mounted in passage of central air conditioner system, and operation principle is easily molten using what is installed on valve
The temperature control of alloy, using the effect of Action of Gravity Field and spring mechanism, when fire occurs, flame invasion air channel, high temperature makes
Fusible alloy on valve melts, or memorial alloy is produced deformation makes valve close automatically, is passed through for air channel and fire compartment
The occasion worn；
Existing blower fan fire resisting damper is typically also engaged to be led to by what the louvre blade in frame, frame and control louvre blade rotated
Wind component；The general plugged and fixed of louvre blade has STATEMENT OF FEDERALLY SPONSORED, realizes rotation together by connecting rod, existing STATEMENT OF FEDERALLY SPONSORED as shown in figure 1,
Its STATEMENT OF FEDERALLY SPONSORED is realized and branch piece 2 by quadrangular 1, branch piece 2 and alignment pin 3, quadrangular 1 and alignment pin 3 by being interference fitted
Connection, so as to need to knock in quadrangular 1 and alignment pin 3 in branch piece 2, but because the thinner thickness of branch piece 2 itself, alignment pin 3 strike
It is short to enter the length of branch piece 2, the branch piece that easily comes off 2, and when quadrangular 1 knocks in branch piece 2, its branch piece 2 is easily deformed.
Utility model content：
The purpose of this utility model and provides structure on a kind of blower fan fire resisting damper and changed aiming at the deficiency of prior art
The STATEMENT OF FEDERALLY SPONSORED entered, it is avoided that the deformation of branch piece, facilitates the connection of quadrangular and branch piece, while strengthens alignment pin and branch piece
Bonding strength.
The improved STATEMENT OF FEDERALLY SPONSORED of structure on a kind of blower fan fire resisting damper, including quadrangular, form in a side wall of quadrangular straight
First grooving of angle triangle, form in another side wall relative with the first grooving on quadrangular and be inverted the of right angled triangle
Two groovings, the second grooving are distributed in the upside of the first grooving, and quadrangular upper sleeve has a branch piece of cam-like, bending forming in branch piece
Limited bit slice, banking stop are plugged in the first grooving and the second grooving of quadrangular respectively；Positioning is plugged with described branch piece
Pin, the bottom of alignment pin forms riveted holes and is fixed on by T-shaped riveting parts in branch piece.
The upper/lower terminal of the quadrangular forms fillet.
The branch piece is made up of the connecting portion between great circle, roundlet and connection great circle, roundlet, the center of circle shaping of branch piece great circle
There is rectangular opening, banking stop is molded on the relative two side of rectangular opening, and quadrangular is plugged in the rectangular opening of branch piece, alignment pin point
Circle centre position of the cloth in branch piece roundlet.
The alignment pin bottom forms annular boss, and annular boss is resisted against in branch piece, and the top of alignment pin forms
Pin-and-hole.
The beneficial effects of the utility model are：
It is simple in construction, and existing STATEMENT OF FEDERALLY SPONSORED is rectified and improved, convenient when being connected so as to the parts of STATEMENT OF FEDERALLY SPONSORED, while not
The deformation of branch piece can be caused, and effectively strengthens the bonding strength between branch piece and alignment pin.
Brief description of the drawings：
Fig. 1 is the schematic perspective view of existing STATEMENT OF FEDERALLY SPONSORED；
Fig. 2 is the three-dimensional structural representation of the utility model；
Fig. 3 is the half-sectional structural representation of the utility model.
In figure：1st, quadrangular；11st, the first grooving；12nd, the second grooving；2nd, branch piece；21st, banking stop；3rd, alignment pin；31st, ring
Shape boss；32nd, pin-and-hole；33rd, riveted holes；4th, riveting parts.
Embodiment：
Embodiment：As shown in Fig. 2,3, the improved STATEMENT OF FEDERALLY SPONSORED of structure on a kind of blower fan fire resisting damper, including quadrangular 1, four ribs
Form the first grooving 11 of right angled triangle in one side wall of post 1, another side wall relative with the first grooving 11 on quadrangular 1
On form the second grooving 12 for being inverted right angled triangle, the second grooving 12 is distributed in the upside of the first grooving 11, on quadrangular 1
It is inserted with the branch piece 2 of cam-like, the limited bit slice 21 of bending forming in branch piece 2, banking stop 21 is plugged on the first of quadrangular 1 respectively
In the grooving 12 of grooving 11 and second；Alignment pin 3 is plugged with described branch piece 2, the bottom of alignment pin 3 forms riveted holes 33 simultaneously
It is fixed on by T-shaped riveting parts 4 in branch piece 2.
The upper/lower terminal of the quadrangular 1 forms fillet.
The branch piece 2 is made up of great circle, roundlet and connection great circle, the connecting portion between roundlet, the center of circle of the great circle of branch piece 2 into
Type has rectangular opening, and banking stop 21 is molded on the relative two side of rectangular opening, and quadrangular 1 is plugged in the rectangular opening of branch piece 2, fixed
Position pin 3 is distributed in the circle centre position of the roundlet of branch piece 2.
