Title:
POLYGONAL CONNECTION HOLE STRUCTURE
Document Type and Number:
Japanese Patent JP2016183731
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a polygonal connection hole structure.SOLUTION: A polygonal connection hole structure of this invention is mounted on a female end item so as to connect the female end item with another male end item. The connection hole has several teeth and these teeth are relatively spaced apart under a prescribed angle, a connecting end of the male end item has several protrusions and these protrusions correspond to the teeth, cause the male end item to pass through the connection hole and further fix it. When a rotating motion is applied from outside after the male end item passes through the connection hole, friction occurs at the inner wall surfaces of these teeth and outer surfaces of the protrusions to generate a power feed-back or cause these protrusions to be compressed, thereby after the protrusions are engaged into recessed groove of these teeth after passing through the teeth, the protrusions are returned back to original positions and set or crossed to each other and engaged, abutted against the rear surfaces of the connection holes to form a fixed state through connections.SELECTED DRAWING: Figure 1
