Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, wherein the embodiments of the present invention are described in detail with reference to the accompanying drawings, for example, the shapes and structures of the respective members, the mutual positions and connection relationships between the respective portions, the functions and operation principles of the respective portions, and the like.
As fig. 1-7, the utility model discloses a ball round pin quick connect structure, including ball round pin assembly 1 and knuckle body 2, be equipped with the mounting hole 21 that is used for installing pin 11 of ball round pin assembly 1 on the knuckle body 2, install jump ring 3 through draw-in groove 12 on ball round pin assembly 1's the pin 11, mounting hole 21 includes taper hole section 211 and joint section 212 along the axial, and the bottom diameter of taper hole section 211 is less than the diameter of jump ring 3, and taper hole section 211 is equipped with the annular joint face 22 with 3 complex of jump ring with the junction of joint section 212.
In a preferred embodiment, the side surface of the snap spring 3 is a snap spring side wall tapered surface a, and the taper α 2 of the snap spring side wall tapered surface a is the same as the taper α 2 of the side wall surface a of the taper hole section 211. Can reduce the jamming like this when the lateral wall of jump ring 3 slides along the lateral wall of taper hole section 211, the external diameter of the jump ring 3 of being convenient for shrinks.
Preferably, the top surface of the snap spring 3 includes a snap spring support surface c at the inner periphery and a snap spring end surface tapered surface B at the outer periphery, the annular snap surface 22 is a tapered surface B, and the taper α 1 of the snap spring end surface tapered surface B is the same as the taper α 1 of the tapered surface B of the annular snap surface 22. So be convenient for at the external diameter of jump ring 3 in the in-process of expansion under the elastic return effect, realize through the slip mode, guarantee that the external diameter of jump ring 3 can expand to the degree that can the chucking at annular joint surface 22.
