[0027] When the protective cap 7 is to be fixed on the oxygen cylinder 1, first the limiting column 9 is inserted into the limiting rotating groove 3, then the rotating plate 11 is rotated to make the buckle 18 sleeve on the surface of the limiting block 5, and finally the threaded rod 13 is rotated to drive the driven plate 16 to move upward until the buckle 18 is buckled into the slot 6, thereby fixing the protective cap 7 on the oxygen cylinder 1 to protect the switch valve 2. This fixing method is simple to operate, convenient and fast. At the same time, the limiting column 9 is inserted into the limiting rotating groove 3 and the buckle 18 is buckled into the slot 6 to provide double installation reinforcement for the protective cap 7, thereby making the installation of the protective cap 7 more stable.

[0028] Embodiment 2

[0029] On the basis of the first embodiment, in order to install the protective cap 7 on the upper surface of the oxygen cylinder 1, a switch valve 2 is provided and fixedly connected to the upper surface of the oxygen cylinder 1, a limit rotation groove 3 is provided on the outer side of the upper surface of the oxygen cylinder 1, a slot 4 is provided at the end of the limit rotation groove 3, a through groove 8 is provided on the side of the protective cap 7, and a limit column 9 is fixedly connected to the lower surface of the protective cap 7, and the limit column 9 is a cylindrical structure;

This installation method is simple to operate, convenient and fast, and the through groove 8 opened on the surface of the protective cap 7 can facilitate the connection of the switch valve 2 with the oxygen supply pipeline.

[0031] Embodiment 3

[0032] On the basis of the second embodiment, in order to fix the protective cap 7 on the upper surface of the oxygen cylinder 1, a limit block 5 is provided and fixedly connected to the side of the upper end of the oxygen cylinder 1.

The threaded rod 13 drives the driven plate 16 on the surface of the driving shaft 15 to move upward through the spiral transmission with the threaded seat 12 until the buckle 18 is buckled into the slot 6. The sliding column 17 can ensure that the driven plate 16 is more stable when moving, so that the protective cap 7 is fixed on the oxygen cylinder 1 to protect the switch valve 2. This fixing method is convenient and fast, saves time and effort, and makes the installation of the protective cap 7 more stable.

[0034] In actual use, when the protective cap 7 is to be fixed on the oxygen cylinder 1, the limiting column 9 is first inserted into the limiting rotation groove 3, and then the rotating plate 11 is rotated to make the buckle 18 sleeve on the surface of the limiting block 5, and finally the threaded rod 13 is rotated to drive the driven plate 16 to move upward until the buckle 18 is buckled into the slot 6, thereby fixing the protective cap 7 on the oxygen cylinder 1 to protect the switch valve 2.
