Abstract
A connecting fitting includes a body having a cam surface and an inserting assembly which is pivotally connected with the body. The inserting assembly includes an inserting member and at least one expandable member mounted between the body and the inserting member. The expandable member includes an expandable portion and a lip portion extending from the expandable portion. A compressible space is defined by the expandable portion and the lip portion, and the expandable portion has a plurality of snap portions. When the body is axially turned relative to the inserting assembly at a certain angle to generate a push force, the snap portions will be expanded outwardly by the push force.
Claims10
A connecting fitting, comprising:
- a body having a cam surface thereon;
- an inserting assembly comprising an inserting member, at least a pair of expandable members disposed in reverse relation one to another, and a plug insertable within an installation hole formed within an object;
- said inserting member comprising a head portion and a body portion extending from said head portion, said body portion being pivotally connected to said body;
- said pair of expandable members mounted between said body and said head portion of said inserting member, each of said expandable members comprising an expandable portion and a lip portion extending from said expandable portion, said expandable portions and said lip portions of each of said pair of expandable members cooperatively defining a compressible space therebetween, and each said expandable portion comprising a plurality of notches and snap portions;
- and
- said plug fitted on said body portion of said inserting member and located between said pair of expandable members and said body, wherein when said body is rotationally displaced, said expandable members are compressed between said plug and said head portion of said inserting member for radial displacement of said expandable members into engagement with an inner surface of said object formed by said hole.
A connecting fitting, comprising:
- a body comprising a pair of lugs spaced from each other, a slot formed between said pair of lugs, and a connecting hole penetrating through said pair of lugs, said pair of lugs each having a first surface and a second surface, a first distance defined from the center of said connecting hole to said first surface, a second distance defined from the center of said connecting hole to said second surface, said first distance and said second distance being different;
- an inserting assembly, said inserting assembly comprising an inserting member, at least a pair of expandable members disposed in reverse relation one to another, and a plug insertable within an installation hole formed within an object;
- said inserting member comprising a head portion and a body portion extending from said head portion, said body portion being pivotally connected to said body;
- said pair of expandable members mounted between said body and said head portion of said inserting member, each of said expandable members comprising an expandable portion and a lip portion extending from said expandable portion, said expandable portions and said lip portions of each of said pair of expandable members cooperatively defining a compressible space therebetween, each said expandable portion comprising a plurality of notches and snap portions;
- and
- said plug fitted on said body portion of said inserting member and located between said pair of expandable members and said body, wherein when said body is rotationally displaced, said expandable members are compressed between said plug and said head portion of said inserting member for radial displacement of said expandable members into engagement with an inner surface of said object formed by said hole.
