In figure, cylinder 1, annular protrusion 11, first annular face 111 of inclining, the second annular incline face 112, the first arc angling 12, Plum blossom Hexagon hole 13, boss 14,141, the third annular that arches upward incline face 142, the second arc angling 143, third arc angling 144。

Specific embodiment

As shown in Figs 1-4, this cylinder barrel is set on 1 upper end outer part of cylinder including the cylinder 1 in upper end opening lower end closed There is annular protrusion 11, annular protrusion 11 is connected and is connected as a single entity structure with cylinder 1, between 11 lower end of annular protrusion and cylinder 1 Equipped with first annular face 111 of inclining, it is equipped with by outer end to inner end gradually between the inside of 11 upper end of annular protrusion on the outside of 1 upper end of cylinder The second annular reduced is inclined face 112, is formed with the first arc angling 12 between 1 side wall of 1 bottom of cylinder and cylinder, the first arc falls The thickness at angle 12 is gradually reduced by middle part to both ends until the thickness phase with 1 side wall of the thickness of 1 bottom of cylinder and cylinder respectively Match, plum blossom Hexagon hole 13 is equipped in the middle part of 1 bottom outside of cylinder, 1 bottom inside of cylinder is equipped with boss 14, and boss 14 is located at plum blossom 13 inner end of Hexagon hole.

More specifically, the ratio between thickness of the thickness of 1 bottom of cylinder and 1 side wall of cylinder is 3.78:2.27, the first arc is fallen The ratio between the thickness and the thickness of 1 bottom of cylinder at 12 middle part of angle are 4.35:3.78；Boss 14 is connected and is integrally formed with cylinder 1, convex 14 top surface of platform is equipped with by center and arches upward 141, and 141 sides of arching upward are to forming from top to bottom gradually inclined the between 14 lateral margin of boss Three annulars are inclined face 142, and third annular, which is inclined, forms the second arc angling 143,14 side of boss between 14 sidewall upper of face 142 and boss Third arc angling 144 is formed between 1 bottom of wall lower end and cylinder；The axial length of annular protrusion 11 and the axial direction of cylinder 1 are long The ratio between degree is 1:3.5；The ratio between diameter and the internal diameter of cylinder 1 of boss 14 are 18.5:50.
