Abstract

The utility model discloses a rapid screwed nipple, which comprises a cylinder body. One end of the cylinder body is provided with a thread sleeve and the other end of the cylinder body is provided with a threaded rod opening. A threaded rod is of a cylindrical shape and is divided into a plurality of clacks along the axial direction. A cavity for containing a guide rod is formed in the axial direction in the middle of the threaded rod. When an expansive force is applied by the guide rod to the inside of the threaded rod, the clack-shaped cylinder is expanded longitudinally so that the diameter of the whole threaded rod is increased. When the expansive force is not applied to the inside of the threaded rod, the diameter of the threaded rod is returned to a initial state. The threaded rod is provided with a clamping groove for clamping an internal screw thread of a workpiece along the circumferential surface in a surrounding mode. The end of the threaded rod, which is positioned in the cylinder body, is fixedly connected with a piston. The other end of the piston is in threaded connection with a spring guide seat. A reset spring is sleeved outside the spring guide seat. The thread sleeve is provided with a handle. The handle can be used for driving the spring guide seat to move through a key board and a pressure head. By matching of the threaded rod and the guide rod, the rapid screwed nipple can be rapidly connected with an inner threaded hole of the workpiece, so that the combination and loosening time is shortened, the efficiency is improved, the labor intensity of workers is reduced and the production cost of enterprises is reduced.

Embodiment

Specific embodiment of the utility model, referring to figs. 1 through Fig. 4, a kind of quick inipple comprises cylinder body 1, side of cylinder block is provided with fluid passage 11.Cylinder body one end is provided with swivel nut 5, and the other end is provided with tooth bar opening.

Described tooth bar 2 is the cylinder that pintongs 1/4 cylindrical body 2A/2B/2C/2D forms, it can be along the tooth bar opening shaft of cylinder body to activity, form cavity 23 in the middle of this pintongs 1/4 cylindrical body to hold guide rod 6, when this tooth bar inside is subjected to the expansive force of guide rod 6, its pintongs radial expansion is respectively opened, make the diameter of whole tooth bar become big, and when not being subjected to expansive force, be returned to original state again.Tooth bar upper edge circumferential surface is equipped with the draw-in groove 21 that is used for clamping workpiece internal thread.Tooth bar one end is arranged in outside the cylinder body 1, is positioned at the fixedly connected piston 3 of the other end of cylinder body 1.Be provided with seal ring 33 and seal ring 34 between this piston 3 and cylinder body 1 inwall, and be provided with seal ring 35 and cushion block 36 between the guide rod 6.

Be provided with seal ring 22 between tooth bar 2 and the cylinder body 1.The other end spiral that is provided with spring 31 and spring housing 32. these pistons 3 between piston 3 and the guide rod 6 is connected a spring guide bracket 4, and this spring guide bracket 4 can endwisely slip in cylinder body.Its outer socket one Returnning spring 41, these Returnning spring 41 1 ends are connected to the projection 42 of spring guide bracket, the step butt in the cushion block 43 in the other end butt cylinder body, this cushion block 43 and cylinder body.

Swivel nut 5 is provided with one handle 9, thereby it articulates by threaded 91 this handle can be rotated around this threaded 91, articulate a key plate 8 by pin 81 in addition on this handle, the other end of key plate 8 articulates a pressure head 7 by pin 82, and this pressure head 7 stretches in the cylinder body by the opening on the swivel nut.

One end of guide rod 6 is fixedlyed connected with swivel nut the inner, and the other end extend in the cavity of tooth bar 2, and the diameter of this guide rod 6 dwindles from inside to outside.

Principle of the present utility model is as follows: referring to Fig. 1, this moment, handle was a releasing orientation, and guide rod stretches out in tooth bar outer end, and in this state, the tooth bar is subjected to the extruding of guide rod and expands, and diameter is maximum.Referring to Fig. 3, during use, press down handle, because threaded fixes, handle forces the key plate that is connected to handle by pin 19 to press down, and makes the dextrad motion of pressure head in figure.This pressure head so promote the spring guide bracket, Returnning spring is compressed, and and the piston that is spirally connected of this spring guide bracket move right, promote the tooth bar at last to the right, just stretch out to cylinder body 1 right-hand member.And guide rod is owing to be to fixedly connected with swivel nut, and it is motionless also to remain on anchored in place, so the tooth bar just outwards moves with respect to guide rod, and tooth bar outer end no longer is subjected to the extrusion expansion of guide rod, reduced at this moment.At this moment the tooth bar of reduced can be inserted in the internal thread of workpiece.

Release handle, handle disappears to the suppressing action power of key plate and pressure head, and this moment is under the effect of restoring force, spring is unfolded, with the spring guide bracket promote left until lean on swivel nut and piston that this spring guide bracket is spirally connected to left movement, spur the tooth bar at last left, just in cylinder body 1, reclaim.And guide rod is owing to be to fixedly connected with swivel nut, and it is motionless also to remain on anchored in place, so the tooth bar just inwardly moves with respect to guide rod, and this moment, the tooth bar was subjected to the extrusion expansion of guide rod, and diameter becomes greatly.Groove on the tooth bar is connected in the internal thread of workpiece, finishes quick connection procedure.

Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
