Embodiment one:
The present embodiment one provides a kind of ball fan, which is usually used in the heat dissipation etc. of equipment.
Referring to FIG. 1, the ball fan includes center rod structure, which includes that outline border 100 and ball separate
Frame 200.
The ball fan further includes two groups of ball assemblies 300, central spindle 400, flabellum connector 500 and flabellum 600 etc..
The installation pedestal of the center rod structure as ball fan, ball assembly 300, central spindle 400, flabellum connector 500
It is mounted directly or indirectly on the center rod structure with flabellum 600 Deng.
Fig. 1 to 6 is please referred to, the raised cylinder 110 in the middle part of the outline border 100, cylinder 110 is hollow to form cylindrical rolling
Pearl installation cavity 120.200 counter-cylinder 110 of ball separation frame be fixedly mounted, and ball separation frame 200 have at least two every
Block 210, spacer block 210 stretch out from the cavity wall of ball installation cavity 120 to the middle part of ball installation cavity 120, ball installation cavity 120 are divided
It is segmented into ball installation cavity and lower ball installation cavity, is connected in the middle part of upper ball installation cavity and lower ball installation cavity.
Two groups of ball assemblies 300 are separately mounted in ball installation cavity and lower ball installation cavity, at up-down structure.Axis
Core 400 passes through in the middle part of two groups of ball assemblies 300, and flabellum connector 500 and one end of central spindle 400 are fixedly connected, and flabellum 600 is solid
It is scheduled on flabellum connector 500.
Specifically, which can be used arbitrarily fixed form and is fixed on cylinder 110, due to this structure
Middle spacer block 210 and outline border 100 are composed in itself, rather than integrated molding in the prior art, the ball installation cavity of outline border 100
120 be a cylindricality easy to process, and ball installation cavity 120 can be formed in the fabrication process by a fuse, can be fine
Ground guarantees that upper ball installation cavity and lower ball installation cavity are concentric, therefore mold insert dislocation leads to lower opening up and down there is no the prior art
The problem of decentraction, can be very good the service life for extending ball fan, the especially service life of ball and central spindle.
At least two spacer block 210 is distributed around the center line of ball installation cavity 120.The quantity of spacer block 210 can be selected flexibly
It selects, different arrangement modes is also designed to according to the quantity of spacer block 210, if spacer block 210 is three in the present embodiment, this implementation
Three spacer blocks 210 are designed as the center line around ball installation cavity 120 into angular distribution by example, and spacer block 210 arrives center line
Straight line is considered as the radius for the circle that three spacer blocks 210 are constituted, the circle being made of the radius of two neighboring spacer block 210 and the center of circle
Heart angle is 120 °.
Certainly, when spacer block 210 is four, corresponding central angle may be 90 °, and the spacer block 210 of other quantity can be with
This analogizes.
In addition, can also be non-uniform Distribution between spacer block 210, i.e., the central angle size of two neighboring spacer block 210 can also be
It is different.
Spacer block 210 may be designed as arc towards the end face of central spindle 400, consequently facilitating cooperating with central spindle 400.
Spacer block 210 is preferably mounted on newel with removably fixed connection mode, and removably fixed connection mode may be
It is clamped, is spirally connected.
Referring to FIG. 4, ball separation frame 200 provided in this embodiment has at least two stabilizer blades 220, each stabilizer blade 220
It is respectively arranged with a spacer block 210, stabilizer blade 220 is fixed on cylinder 110, and also counter-cylinder 110 is solid to guarantee spacer block 210
It is fixed.
Here spacer block 210 is three, therefore stabilizer blade 220 is also configured as three.Similarly, three stabilizer blades 220 surround ball
The center line of installation cavity 120 is at angular distribution.
Ibid, the quantity for stabilizer blade 220 and distribution mode are also not limited to mode shown in attached drawing, can also same spacer block
210 are equally changed.
Further, please continue to refer to Fig. 2,3,4,7, ball separation frame 200 can also include pedestal 230, the stabilizer blade 220
Setting is upwardly extended from pedestal 230.The side wall of cylinder 110 has at least two flutings 130, and pedestal 230 is stuck in the one of cylinder 110
End, stabilizer blade 220 are extend into fluting 130 from ball installation cavity 120, and are clamped with the side wall 140 of fluting 130.It is clamped rear leg
220 inner wall and the inner wall of ball installation cavity 120 substantially remain in same cambered surface.
Specifically, fluting 130 is three, and 130 shape of slotting is the square groove to match with stabilizer blade 220.This three flutings
130 also around ball installation cavity 120 center line at angular distribution, certainly, 220 quantity of stabilizer blade and distribution mode difference can also be led
Cause the quantity of fluting 130 and distribution mode difference.
Fig. 1,4,5 and 7 are please referred to, the specific structure of clamping can be stabilizer blade 220 and the side of fluting 130 is provided with card
Button 240, buckle 240 and the side wall 140 of fluting 130 are clamped.
Ball separation frame 200 and outline border 100 can be used plastics and be made.First by ball separation frame 200 under outline border 100
Portion is inserted into ball installation cavity 120, and the compression of stabilizer blade 220 of ball separation frame 200 is slightly shunk, when the buckle 240 on stabilizer blade 220 moves
When moving at fluting 130,200 selfer power of ball separation frame makes to buckle 240 side walls for being stuck in fluting 130, to avoid rolling
Pearl separation frame 200 is dropped out out of ball installation cavity 120.
The above content is specific embodiment is combined, further detailed description of the invention, and it cannot be said that this hair
Bright specific implementation is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, it is not taking off
Under the premise of from present inventive concept, a number of simple deductions or replacements can also be made.
