[0014] This invention provides a gas cylinder filling and pressurization system. Compared with the prior art, it has the following advantages:

[0015] 1. The cylinder output drives the extension ear to rotate the ring frame. The ring frame drives the slider to slide along the inside of the arc groove through the arc groove. The slider drives the mounting block to slide along the straight groove. At the same time, the mounting block drives the threaded rod to move, thereby adjusting the distance between each threaded rod and the shaft. This allows it to adapt to flanges of different specifications, solving the compatibility problem caused by inconsistent specifications in traditional flange connections and improving the system's versatility and installation efficiency.

Several circularly distributed arc grooves 213 are opened inside the ring frame 212. A slider 214 is slidably mounted inside the arc grooves 213. An extension ear 219 is fixed at one end of the edge of the ring frame 212. A disc cover 215 is installed at the outer end of the ring frame 212. Several circularly distributed straight grooves 216 are opened inside the disc cover 215. An installation block 217 is slidably mounted inside the straight grooves 216. The installation block 217 is rotatably mounted with the slider 214. A threaded rod 218 is installed at the outer end of the installation block 217.

[0026] The drive assembly 22 is mounted on the disc base 211 and is used to drive the ring frame 212 to rotate.

[0027] In this embodiment, when the ring frame 212 rotates, it drives the slider 214 to slide along the inside of the arc groove 213 through the arc groove 213, and the slider 214 drives the mounting block 217 to slide along the straight groove 216. At the same time, the mounting block 217 drives the threaded rod 218 to move, thereby adjusting the distance between each threaded rod 218 and the shaft center at the same time, so as to adapt to flanges of different specifications, solve the compatibility problem caused by the non-uniformity of specifications in traditional flange connections, and improve the versatility and installation efficiency of the system.

[0028] Specifically, the main component 21 also includes a threaded hole 2110 opened inside the mounting block 217, and an internal hex bolt 2111 is inserted into the threaded rod 218 and threadedly installed in the threaded hole 2110 on the mounting block 217.

[0030] Specifically, the drive assembly 22 includes a shaft bracket 221 fixed to the edge of the disc base 211, a cylinder 222 pivotally connected to the shaft bracket 221, and the output end of the cylinder 222 pivotally connected to the extension ear 219.

[0031] In this embodiment, the output end of the cylinder 222 drives the extension ear 219 to rotate the ring frame 212.

[0032] Specifically, the main component 21 also includes a slot 2112 formed inside one end of the edge of the base 211, and the extension ear 219 is located in the slot 2112.

[0033] In this embodiment, the slot 2112 is used to avoid motion interference with the movement of the extension ear 219.
