The technical solution of the utility model is: a kind of swivel joint of design, this swivel joint is mainly by swivel joint axle sleeve, swivel joint mandrel and swivel joint connect seat three part and are formed by connecting, and swivel joint mandrel connects described axle sleeve by non-threaded connected mode and connects seat.
Described swivel joint axle sleeve is provided with swivel joint spacer, the first groove and the second groove, described second groove diameter is more than described first groove, described swivel joint mandrel is provided with the first axle body, the second axle body and three-axis body, the diameter of described the second axle body is more than the first axle body, described the first axle body and described first fit depressions, described the second axle body and the second fit depressions, described swivel joint mandrel can rotate in axle sleeve, and connect seat and linked together with described three-axis body by non-threaded connected mode.
Also being placed with, in described second groove, the outside framework oil seal matched with the first axle body, outside framework oil seal is arranged between swivel joint spacer and the first groove, and swivel joint is limited between outside framework oil seal and swivel joint axle sleeve.
Further, described the first axle body being provided with the first jump-ring slot, be placed with jump ring/back-up ring in jump-ring slot, described outside framework oil seal is limited between the first groove and the first jump-ring slot.
Further, described swivel joint spacer is provided with the second jump-ring slot, is placed with jump ring/back-up ring in jump-ring slot, between spacer and the second jump-ring slot, is placed with the bearing matched with the first axle body.
Further, the bearing matched with the first axle body has more than a pair.
Further, described three-axis body is provided with seal groove.
Further, described connection seat is connected by sunk screw with described swivel joint mandrel.
Further, described swivel joint sleeve length is 86mm, and the first groove diameter is 19mm, and the second groove diameter is 35mm, upper deviation 0.02mm, lower deviation 0.007mm, and axle sleeve hollow diameters is 9mm.
Further, the described swivel joint a diameter of 17mm of mandrel the first axle body, upper lower deviation is respectively-0.007mm and-0.02mm, the a diameter of 21mm of the second axle body, the a diameter of 20mm of three-axis body, upper lower deviation is respectively-0.02mm and-0.05mm, and swivel joint mandrel total length is 78mm, and the hollow diameters of described swivel joint mandrel is 9mm.
Further, the hollow diameters of described connection seat is 9mm.
