Description

Technical Field

[0001] The invention relates to the technical field of pressure reducers, and in particular to a pressure maintaining platform for a pressure reducer. Background Art

[0002] A pressure reducer is a device that reduces the high-pressure oxygen gas stored in an oxygen cylinder to the low-pressure oxygen required for gas welding. Since the gas pressure in the oxygen cylinder is relatively high, and the gas pressure used for gas welding and gas cutting is relatively low, a pressure reducer is needed to convert the gas pressure, so as to facilitate subsequent gas welding and gas cutting processing. The pressure reducing device pressure maintaining platform plays a supporting and limiting role when the pressure reducing device is connected to the oxygen cylinder gas pipe. The traditional pressure maintaining platform is generally installed on the outside of the gas outlet, and then the two sides are limited by nuts. After that, the pressure reducing device is placed on the pressure maintaining platform and the pressure reducing device is connected to the gas pipe of the oxygen cylinder.

[0003] During the installation and use of the traditional pressure reducing device pressure maintaining platform, since the pressure maintaining platform is mounted on the outside of the air pipe of the oxygen cylinder and is restricted by nuts on both sides, the position of the pressure maintaining platform needs to be adjusted when the pressure reducing device interface is connected to the oxygen cylinder interface. When adjusting, the nut at one end needs to be turned first, and then the pressure maintaining platform is pushed, and then the other set of nuts is turned to restrict the pressure maintaining platform. After adjustment, the pressure reducing device is placed on the pressure maintaining platform to check whether it is suitable. If it is not suitable, a second adjustment needs to be performed according to the above operation. Therefore, the adjustment method of the pressure reducing device pressure maintaining platform during use is relatively cumbersome and time-consuming, which leads to inconvenience in use. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that when the pressure-maintaining platform of the pressure reducer mentioned in the above-mentioned background technology is adjusted during use, it is necessary to first screw a set of nuts, push the pressure-maintaining platform, and then screw another set of nuts to fix it. After multiple adjustments, it is adjusted to a suitable position, which makes the adjustment method of the pressure-maintaining platform more cumbersome and time-consuming, thereby inconvenient to use.
