Furthermore, at least one support lug is fixedly arranged on the outer wall of the locking sleeve.
Furthermore, the inner wall of the first joint is provided with a second annular concave part, and the outer wall of the second joint is provided with an annular convex part matched with the second annular concave part.
Further, still including setting up the sealing washer between first joint and second joint.
From the above description of the structure of the present invention, it can be seen that the present invention has the following advantages:
the utility model comprises a first joint connected with an oxygen lance water inlet pipe, a second joint connected with an oxygen lance water outlet pipe and a locking sleeve, wherein the locking sleeve is detachably sleeved outside the first joint and the second joint. Therefore, the structure of the oxygen lance is simple in design, the first joint and the second joint can be kept fastened or separated from each other by screwing and loosening the locking sleeve, the oxygen lance can be quickly replaced and installed, the maintenance time is shortened, the working strength of workers is reduced, and the maintenance efficiency of the oxygen lance is greatly improved.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in figure 1, the oxygen lance quick-change device comprises a first connector 1, a second connector 2 and a locking sleeve 3, wherein the first connector 1 is connected to a water inlet pipe of an oxygen lance, the second connector 2 is connected to a water outlet pipe of the oxygen lance, and the locking sleeve 3 is detachably sleeved outside the first connector 1 and the second connector 2 and used for realizing the fastening and the separation of the first connector 1 and the second connector 2. Therefore, the structure of the oxygen lance maintenance device is simple in design, the first connector 1 and the second connector 2 can be kept fastened or separated from each other by screwing and loosening the locking sleeve 3, the oxygen lance is quickly replaced and installed, the maintenance time is shortened, the working strength of workers is reduced, and the maintenance efficiency of the oxygen lance is greatly improved.
As shown in fig. 1 to 4, the inner wall of the locking sleeve 3 is provided with a first annular recess 31 distributed in a stepped manner, and the upper end of the locking sleeve is provided with two claws 32; the outer wall of the first joint 1 is provided with a first annular boss 11 matched with the first annular concave part 31. The outer side walls of the first annular boss 11 and the first annular recess 31 are attached to each other, so that the locking sleeve 3 is detachably sleeved outside the first connector 1. The outer wall of the second joint 2 is provided with a second annular boss 21, and the second annular boss is provided with a spiral bulge 22. The spiral protrusion 22 is provided with a notch for two claws 32 of the locking sleeve 3, and the two claws 32 are clamped on the spiral protrusion 22 after passing through the notch. In actual production, the size and the edge of the clamping jaw can be designed according to specific matching requirements, so that the clamping jaw can be flexibly adapted to the spiral protrusion 22, and the clamping jaw can be conveniently clamped on the spiral protrusion 22 after passing through the notch.
As shown in fig. 1 to 2, two lugs 33 are fixed to the outer wall of the locking sleeve 3 for tightening and loosening the locking sleeve 3. In the actual operation process, when the locking sleeve 3 is sleeved outside the first joint 1 and the second joint 2, the two support lugs 33 are held forcefully, and the locking sleeve 3 is rotated, so that the first joint 1 and the second joint 2 can be fastened and separated quickly, the operation is easy, the time for workers to replace the oxygen lance is reduced, and the overhauling efficiency of the oxygen lance is improved greatly.
