State the connecting plate of first surface plate and the support axis connection；
The first surface plate is integrally located on the inside of the blade edge, the two sides sideline of the connecting plate and the blade afterbody
Two extension wire shapeds being extended to form towards the support shaft along itself direction of a curve of two sides sideline are identical and position one by one
It is corresponding.
Preferably, the first surface plate covers the position where the blade center of gravity.
Preferably, the first surface plate becomes narrow gradually along the direction far from the support shaft.
Preferably, the connecting plate becomes narrow gradually along the direction close to the support shaft, the maximum width of the connecting plate
Less than or equal to the width of the blade tail end.
Preferably, gap distribution between the blade afterbody and the support shaft.
Preferably, the connecting plate is the second curved slab, curved surface and the blade afterbody where second curved slab
It is bonded to each other along itself curved surface direction towards the curved surface that the support shaft extends to form and shape is identical.
Preferably, the axial flow blower further includes the rivet for connecting the first surface plate and the blade.
Due to the application of the above technical scheme, compared with the prior art, the invention has the following advantages: a kind of axis of the present invention
Flow fan, first surface plate and the cooperation contact of blade afterbody curved surface, contact area are contacted than conventional connecting bracket with blade plane
Linear area it is bigger, be connected and fixed fastness height；The extension wire shaped in connecting plate two sides sideline and blade afterbody two sides sideline
Unanimously, effective acting area of blower is improved, fan performance and efficiency are improved, the vortex and wadding stream of fan airflow are reduced,
Reduce fan vibration and noise.
Detailed description of the invention
Attached drawing 1 is the front view of apparatus of the present invention；
Attached drawing 2 is the structural schematic diagram of apparatus of the present invention.
Wherein: 1, support shaft；2, blade；3, first surface plate；4, connecting plate；5, rivet.
Specific embodiment
The technical solution of the present invention will be further described below with reference to the accompanying drawings.
Referring to shown in Fig. 1-2, a kind of above-mentioned axial flow blower, including support shaft 1, for driving support shaft 1 around Pivot Point Center
The motor (not shown) of line direction rotation, multiple be along the circumferential direction successively spaced evenly distributed are set to 1 outside of support shaft
The connector of circumference, the blade 2 being connected on connector correspondingly.Blade 2 is tail portion close to the side of support shaft 1, far
Side from support shaft 1 is head, gap distribution between 2 tail portion of blade and support shaft 1.
Above-mentioned connector include curved surface cooperation the first surface plate 3 for being attached at 2 tail portion one side of blade, both ends respectively with
The connecting plate 4 that first surface plate 3 and support shaft 1 connect.
In the present embodiment, first surface plate 3 is integrally located on the inside of 2 edge of blade, the curve form of first surface plate 3 with
The curve form of 2 tail portion joint place of blade is identical, first surface plate 3 and the cooperation contact of 2 tail section curved surface of blade, contact area
Linear area than conventional connecting bracket and 2 plane contact of blade is bigger, is connected and fixed fastness height.
In the present embodiment, first surface plate 3 covers the position where 2 center of gravity of blade, and first surface plate 3 is along far from support
The direction of axis 1 becomes narrow gradually.It is arranged by this, while guaranteeing to be connected firmly to blade 2, reduces first surface plate 3
Area, effectively reduce fan energy consumption.
The two sides sideline of above-mentioned connecting plate 4 and the two sides sideline of 2 tail portion of blade are prolonged along itself direction of a curve towards support shaft 1
Stretch that the two extension wire shapeds to be formed are identical and position corresponds.Position said herein corresponds, and refers to 4 two sides of connecting plate
Sideline overlaps with two extension lines along the axial orthographic projection of support shaft 1 along the axial orthographic projection of support shaft 1.4 liang of connecting plate
Side line is consistent with the extension wire shaped in 2 two sides of tail sideline of blade, improves effective acting area of blower, fan performance and effect
Rate is improved, and is reduced the vortex and wadding stream of fan airflow, is reduced fan vibration and noise.
In the present embodiment, connecting plate 4 is the second curved slab, and the curved surface and 2 tail portion of blade where the second curved slab are along certainly
Body curved surface direction is bonded to each other towards the curved surface that support shaft 1 extends to form and shape is identical.It is arranged by this, is further increased
Fan performance and efficiency.
In the present embodiment, connecting plate 4 becomes narrow gradually along the direction close to support shaft 1, and the maximum width of connecting plate 4 is equal to
The width of 2 tail end of blade.
A kind of above-mentioned axial flow blower further includes the rivet 5 for connecting first surface plate 3 and blade 2.In the present embodiment,
The rivet 5 is large oval head rivet 5.
It is designed by the structure to connector, keeps the curved surface of 2 tail portion of blade identical as first surface plate 3, make blade 2
The extension line in two sides of tail sideline is identical as the second curved slab two sides sideline, and after blade 2 and connector assembling, the two forms one
A entirety that Effective power is done to blower improves effective acting area of blower, improves fan performance and efficiency, reduces fan airflow
Vortex and wadding stream, reduce fan vibration and noise.
