[0024] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0025] To address the problems existing in the background art, this application proposes the following technical solution: a stainless steel valve handle that is easy to install.

[0026] The specific technical solution includes a valve body 1, a valve stem 2, and a handle 3. A disassembly / assembly mechanism 4 is provided on the lower side of the valve body 1 and the handle 3. The disassembly / assembly mechanism 4 corresponds to the valve stem 2, which is located on the upper side of the valve body 1. The handle 3 is connected to the valve stem 2 via the disassembly / assembly mechanism 4. The disassembly / assembly mechanism 4 includes a limiting plate 7, a plug-in plate 8, and a rotating shaft 10. The plug-in plate 8 is fixedly installed on the lower side of the limiting plate 7. An installation cavity 9 is opened inside the plug-in plate 8. The rotating shaft 10 is rotatably installed inside the installation cavity 9. Four sliding grooves 12 are opened on the circumference of the inner wall of the installation cavity 9. A locking block 13 is slidably installed in each of the four sliding grooves 12. A toothed plate 14 is fixedly installed on one side of the locking block 13. A gear 11 is fixedly installed on the circumference of the rotating shaft 10. All four toothed plates 14... The four toothed plates 14 are staggered from top to bottom and mesh with the gear 11, so that when the gear 11 drives the four toothed plates 14 and the four locking blocks 13 to move, they will not interfere with each other. The valve stem 2 has a plug groove 5 on the upper side, and four locking grooves are opened on the inner wall of the plug groove 5. The plug plate 8 is plugged into the plug groove 5, and the locking block 13 is locked in the locking groove. The bottom of the inner wall of the plug groove 5 has an internal hexagonal groove 6. An internal hexagonal plug is fixedly installed at the lower end of the plug plate 8. The internal hexagonal plug is inserted into the internal hexagonal groove 6. By inserting the internal hexagonal plug into the internal hexagonal groove 6, the plug plate 8 can be limited, and the handle 3 can drive the valve stem 2 to rotate. The handle 3 is fixedly connected to the limiting plate 7.

[0027] Reference Figure 3 and Figure 4 As shown, a limiting mechanism 15 is provided between the limiting plate 7 and the insertion plate 8, and the limiting mechanism 15 is connected to the rotating shaft 10. The limiting mechanism 15 includes a rotating rod 17, a fixed cylinder 18, and a threaded rod 20. A rotating groove 16 is provided on the upper side of the limiting plate 7, and the rotating rod 17 is rotatably installed in the rotating groove 16. The fixed cylinder 18 is eccentrically installed on the upper end of the rotating rod 17. A threaded groove 19 is provided in the fixed cylinder 18, and the threaded rod 20 is threadedly installed in the threaded groove 19. A slot 21 is provided on the upper side of the limiting plate 7, and one end of the threaded rod 20 is inserted into the slot 21. The rotating groove 16 is connected to the mounting cavity 9. The lower end of the rotating rod 17 is fixedly connected to the upper end of the rotating shaft 10. A rotating knob 22 is provided on the upper end of the threaded rod 20. The threaded rod 20 and the threaded groove 19 have a large pitch, so that one end of the threaded rod 20 can be disengaged from the slot 21 after rotating one revolution.

[0028] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0029] In use, when it is necessary to disassemble the handle 3 from the valve stem 2, the rotating knob 22 is turned, causing the threaded rod 20 to rotate. The rotation of the threaded rod 20 allows it to move upward through the threaded groove 19, thereby disengaging one end of the threaded rod 20 from the slot 21 and releasing the restriction on the rotating rod 17. Then, the rotating rod 17 is rotated through the fixed cylinder 18, causing the rotating rod 17 to drive the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 drives the gear 11 to rotate, which in turn drives the four toothed plates 14 to move synchronously. The synchronous movement of the four toothed plates 14 drives the four locking blocks 13 to retract synchronously, causing the locking blocks 13 to retract into the sliding groove 12 and the mounting cavity 9, thereby releasing the restriction and fixation between the plug plate 8 and the valve stem 2. Then, the handle 3 is pulled upward, causing the plug plate 8 to disengage from the plug groove 5, thus completing the disassembly of the handle 3. During installation, the above steps are reversed to easily and quickly fix the handle 3 to the valve stem 2.
