STRUCTURE OF HOSE CONNECTION PART AND JOINT
Document Type and Number:
Japanese Patent JP2022170764
Kind Code:
A
Abstract:
To provide a structure of a hose connection part in which a cylindrical insertion part can be connected to a hose, fluid can be caused to flow immediately, and which can be used.SOLUTION: A structure of a hose connection part includes: a cylindrical insertion part inserted to the inside of a hose; a seal annular projection which projects from an outer surface of the cylindrical insertion part, bites in the hose, and seals the hose and the cylindrical insertion part; a pair of groove formation projections which project from the outer surface of the cylindrical insertion part, in which an engaging radius to be a distance between a projection end and a central axis of the cylindrical insertion part is the engaging radius of the seal annular projection or smaller, and which form an annular groove mutually opposite in an axial direction of the cylindrical insertion part; and an elastic ring which is received by the annular groove, has an engaging radius larger than the engaging radii of the seal annular projection and the groove formation projection, is adhered to an inner surface of the hose, and seals between the hose and the cylindrical insertion part.SELECTED DRAWING: Figure 1
