[0030] Example 2
[0031] Based on Embodiment 1, a rotating mechanism 4 is provided to facilitate subsequent maintenance by personnel. The other end of the rotating mechanism 4 is fixedly connected to the connecting rod 5. The connecting rod 5 has a cylindrical structure and can slide along the connecting groove 6 opened on the main body of the mounting structure 3. The connecting groove 6 has a circular groove structure. The diameter of the threaded end on the rotating mechanism 4 is smaller than the inner diameter of the connecting groove 6. The operator can rotate the rotating mechanism 4, and the threaded end on the rotating mechanism 4 rotates along the threaded hole on the main body of the mounting structure 3, so that the connecting rod 5 slides along the connecting groove 6.
[0032] The connecting rod 5 is rotatably connected to the upper pressing block 8. The upper pressing block 8 is a combination of two "L"-shaped plates. The upper pressing block 8 fits perfectly into the sliding groove 7 opened in the main body of the installation structure 3. The upper pressing block 8 can slide along the sliding groove 7, which has a square groove structure. This allows the upper pressing block 8 to slide along the sliding groove 7, so that the right angle on the upper pressing block 8 presses against the inclined surface on the connecting block 11, as in the example. Figure 8 The structure allows the connecting block 11 to slide along the limiting groove 10 by pressing the right angle of the upper pressing block 8 against the inclined surface of the connecting block 11.
[0033] The connecting block 11 is fixedly connected to the locking block 12. The locking block 12 has an arc-shaped plate structure. The locking block 12 is just locked in the storage groove 16 opened on the inner side of the mounting structure body 3. The locking block 12 can be removed from the storage groove 16 and locked into the locking groove 17 opened on the inner side of the valve body 2. The locking groove 17 has a circular groove structure. One end of the locking block 12 is locked into the locking groove 17, which can fix the valve body 2 on the mounting structure body 3, and then install the valve body 2 on the cylinder body 1.
[0034] A lower extrusion block 9 is fixedly connected to the upper extrusion block 8. The lower extrusion block 9 has a square plate-like structure. One end of the lower extrusion block 9 is set in the lower groove 15 opened on the connecting block 11. The lower groove 15 has a trapezoidal groove-like structure. When one end of the locking block 12 is in the locking groove 17, the lower extrusion block 9 just contacts the inclined surface at the sharp corner of the lower end of the connecting block 11. The upper end of the lower extrusion block 9 is still in the lower groove 15. The operator can rotate the rotating mechanism 4 to make the upper extrusion block 8 slide along the sliding groove 7 and make the lower extrusion block 9 press the inclined surface on the connecting block 11, so that the connecting block 11 can slide along the limiting groove 10.
[0035] The connecting block 11 is a combination of a trapezoidal plate and a square plate fixedly connected. The connecting block 11 fits perfectly into the limiting groove 10 opened on the main body of the installation structure 3. The connecting block 11 can slide along the limiting groove 10, which has a square groove structure, so that the locking block 12 can be moved back into the storage groove 16. At this time, the position of the lower pressing block 9 is as shown in the example. Figure 8 As shown, the above structures work together to facilitate the installation and removal of the valve body 2 on the cylinder body 1 by personnel, making it convenient for actual use without the need for other tools.
[0036] Example 3
[0037] Based on Embodiment 2, a rotating mechanism 4 is provided to improve the performance of the device. The threaded end of the rotating mechanism 4 is threadedly connected to the mounting structure body 3. The threaded end of the mounting structure body 3 can be threadedly connected to the mounting location of the cylinder body 1. A support block 13 is fixedly connected inside the mounting structure body 3. The support block 13 has a circular annular plate structure. A sealing gasket 14 is fixedly connected to the upper surface of the support block 13. The sealing gasket 14 has a circular annular plate structure. When the personnel install the mounting structure body 3 to the mounting location of the cylinder body 1 and thread it, the personnel can install the valve body 2 onto the mounting structure body 3, thus completing the installation of the mounting structure body 3 onto the cylinder body 1. After installation, the sealing gasket 14 fixedly connected to the support block 13 contacts the lower edge of the valve body 2, which can improve its sealing performance.
[0038] In actual use, the rotating mechanism 4 rotates along the threaded hole on the mounting structure body 3, causing the upper pressing block 8 to slide along the slide groove 7, and the lower pressing block 9 to press the inclined surface on the connecting block 11. This allows the connecting block 11 to slide along the limiting groove 10, causing the locking block 12 to move back into the storage groove 16, thus releasing the lock on the valve body 2. It can then be disassembled for maintenance. The structure is simple, making it easy for personnel to install and disassemble the valve body 2 on the cylinder body 1. It is convenient for personnel to use and does not require the use of other tools for disassembly.
