Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, but not as to restriction of the present utility model：
A kind of end cap for having covering of the fan connected in star, including end cap body, it is characterised in that：Described end cap body is four sections of ranks
Terraced axle, is followed successively by cylinder boss 1, the big end of cone boss 2, multidiameter, boss A from front to back, is provided with front of end cap body
Annular groove 7, the section of annular groove 7 is pre-large post-small trapezium structure；Circumferentially uniform three are provided with annular groove 7
Individual reinforcement A3, is provided with circumferentially uniform three reinforcement B5, reinforcement A3 and reinforcement B5 angularly in annular groove 7
Arranged for interval；Three are provided with platform between the outer ring edge of annular groove 7 and end cap body around uniform square of circular shaft
Boss 6, the middle part of square boss 6 are provided with waist-shaped hole 4；The outer ring of cylinder boss 1 be provided with three it is circumferentially uniform convex
Rib, the center of each fin are corresponded and are connected by reinforcement A3 with the center of each waist-shaped hole 4；The big end of end cap body
Circumferentially disposed covering of the fan connected in star 8 is provided with rear end face；In the centrage and top waist-shaped hole 4 of covering of the fan connected in star 8
Heart line arrangement at an acute angle；The angle of covering of the fan connected in star 8 is β, and angle β 9 is acute angle；End cap body is provided centrally with three sections of ladders
Hole, at boss A ends, the small end of three sections of shoulder holes is at 1 end of cylinder boss at the big end of three sections of shoulder holes；Described reinforcement A3 and side
The width of 6 joint of shape boss is more than reinforcement A3 and the width of fin joint；The centrage of described covering of the fan connected in star 8 with
Acute angle between the centrage of top waist-shaped hole 4 is 30 °；Described angle β 9 is 36 °.
When being embodied as, the end cap and the end cap without covering of the fan connected in star 8 for having covering of the fan connected in star 8 need not open two pairs of moulds,
