Embodiment
A kind of specific embodiment as shown in Figure 1, it comprises movable sheath 1 and fixed cover 9, movable sheath 1 is threaded with fixed cover 9.
Be provided with the lock sleeve 4 that is rotationally connected with movable sheath 1 in the movable sheath 1; Lock sleeve 4 is provided with the positive stop lug boss of outside protrusion, and the trepanning of movable sheath 1 is a shoulder hole, and a wide-aperture end is used for being connected with fixed cover 9; Be provided with thrust-bearing 2 in the lock sleeve 4 wide-aperture ends; Thrust-bearing 2 is clipped on the interior step surface of positive stop lug boss and movable sheath 1 on the lock sleeve 4, and the positive stop lug boss on the lock sleeve 4 is away from the porose back-up ring 3 of a side peripheral hardware of thrust-bearing 2, and hole back-up ring 3 is fixed on the movable sheath 1.Make lock sleeve 4 in movable sheath 1, to rotate and can not move axially.
Be provided with connecting sleeve 5 in the fixed cover 9; The trepanning of fixed cover 9 also is a shoulder hole; Make the connecting sleeve limit dais terrace and the oxygen lance limit dais terrace that is used to limit oxygen lance 10 axial displacements that is formed for limiting connecting sleeve 5 axial displacements in the fixed cover 9; Connecting sleeve 5 is away from being provided with flexible rubber ring 7 between the connecting sleeve limit dais terrace in end of movable sheath 1 and the fixed cover 9; Fixed cover 9 is provided with the tight fixed bolt 6 that is used to lock connecting sleeve 5, and like Fig. 1, Fig. 2 and Fig. 3 institute method, an end of connecting sleeve 5 contiguous movable sheaths 1 is provided with a plurality of elasticity card lobes 11; Elasticity card lobe 11 can be that the end by connecting sleeve 5 plucks out a plurality of elongated slots and forms; The inner side surface of elasticity card lobe 11 is provided with boss 12, and oxygen lance limit dais terrace is provided with seal ring 8 in the fixed cover 9, and the internal diameter of seal ring 8 is less than the minimum aperture of the trepanning of movable sheath 1, lock sleeve 4 and connecting sleeve 5.Movable sheath 1, lock sleeve 4, connecting sleeve 5 and fixed cover 9 are on the same axis.
When oxygen lance 10 passes movable sheath 1, lock sleeve 4 and connecting sleeve 5 and is attached on the seal ring 8; And being threaded when reaching certain-length of fixed cover and movable sheath; Elasticity card lobe on the connecting sleeve is inserted in the lock sleeve, and lock sleeve, connecting sleeve and Oxygen tube three hold tightly.
The periphery of elasticity card lobe 11 has tapering; Elasticity card lobe is used to insert the radius of an end of lock sleeve less than the radius of the other end; Also can be at the certain tapering of trepanning face design of lock sleeve 4; And making the pore radius of an end that lock sleeve 4 is used to admit elasticity card lobe 11 greater than the other end pore radius, the tapering of the tapering of the periphery of elasticity card lobe 11 and the trepanning face of lock sleeve 4 can possess simultaneously.
Its working principle is: during use, oxygen lance 10 is inserted into fixed cover 9 from movable sheath 1, contacts with seal ring 8 up to the end face of oxygen lance 10; Make it pass through the direction motion of screw thread with hand dextrorotation movable sheath 1 to fixed cover 9; Drive lock sleeve 4 and move right, elasticity card lobe 11 progresses into lock sleeve 4 in the movement process, makes the boss 12 on the elasticity card lobe 11 hold oxygen lance 10 tightly up to lock sleeve 4 extruding elasticity card lobes 11; Turn movable sheath 1 feeding certain distance to the right again; Drive connecting sleeve 5 and also move right with oxygen lance 10, make oxygen lance 10 compresses seal 8, seal ring 8 is compacted; Thereby realize the sealing between oxygen lance 10 and the fixed cover 9, tighten tight fixed bolt 6.When taking off oxygen lance 10, in the other direction turn movable sheath 1, lock sleeve 4 is thrown off with connecting sleeve 5 under the effect of tight fixed bolt 6, and elasticity card lobe 11 unclamps oxygen lance 10 under the effect of self elastic force, can take off oxygen lance 10 smoothly.The other end of fixed cover 9 is used to connect oxygen source.
