Abstract
A mating connection assembly of the present invention permits quick and efficient connecting and disconnecting of tubular goods. A female box-end connection member has an inner body defining sockets; ball bearings held within such sockets with an outer sleeve. A male pin-end connection member is inserted within the box end connection. By moving the outer sleeve axially, the ball bearings are urged inward toward the male pin-end connection, creating a frictional locking relationship between the female box-end connection member and male pin-end connection member.
Claims9
A connection assembly comprising:
- a) a box end connection member comprising:
- i) a substantially tubular body having an upper end, a lower end, an outer surface, a central through bore extending from said upper end to said lower end, and a plurality of transverse sockets extending through said body member from said outer surface to said central bore;
- ii) at least one lug finger disposed at said lower end of said body;
- b) at least one ball received within said at least one transverse socket;
- c) a sleeve slidably disposed over said body of said box end connection member, said sleeve having an upper end, a lower end, an inner surface and a plurality of spaced circumferential grooves around said inner surface;
- and
- d) a pin end connection member, adapted to be partially received within said box end connection member, comprising:
- i) a substantially tubular body having an upper end, a lower end, an outer surface and a central through bore extending from said upper end to said lower end, and a plurality of circumferential grooves disposed around said body;
- ii) a shoulder member extending radially outward from said body, having at least one lug recess adapted to receive a lug finger of said box end connection member.
