The sealing cover 4 is made of stainless steel and is used to seal the gas cylinder mouth when the low-pressure gas cylinder leaks. An elastic sealing ring 43 matching the gas cylinder is also provided at the lower end of the sealing cover 4 to improve the sealing effect of the gas cylinder, ensure the complete sealing of the leaking gas cylinder, and ensure the treatment effect of the leaking gas cylinder.

[0036] The gas cylinder rack 2 is provided with a plurality of positioning frames 21 that match the gas cylinder and are U-shaped, and the plurality of positioning frames 21 are vertically stacked. A plurality of reinforcing ribs 22 are vertically arranged between the plurality of positioning frames 21. Elastic clamping springs 23 corresponding to the gas cylinder are provided on the inner walls of both sides of the positioning frame 21.

The strength of the gas cylinder rack 2 is ensured by cooperating with the reinforcing ribs 22, and the placed gas cylinder is pressed tightly by cooperating with the elastic clamping springs 23 to ensure the fixing effect of the gas cylinder rack 2 on the gas cylinder.

[0037] A fixing arm 42 is horizontally installed at the rear side of the sealing cover 4. A regulating rod 5 is rotatably connected to the rear side of the fixing arm 42. A fixing rod 6 is vertically slidably connected to the outer side of the regulating rod 5. The fixing rod 6 is vertically fixedly installed on the bottom plate 1. By adjusting the regulating rod 5 in the fixing rod 6, the height of the sealing cover 4 can be conveniently adjusted to adapt to gas cylinders of different sizes and heights, ensuring the applicability in case of being bumped.

[0038] Adjusting holes 7 are correspondingly opened on both the regulating rod 5 and the fixing rod 6, and fixing bolts 8 are arranged in the adjusting holes 7 to ensure the stable fixing of the sealing cover 4 and the use effect of the device.

[0039] This low-pressure gas cylinder treatment device can be used as a fixing bracket for the normal use of the gas cylinder or as a standby for emergency treatment equipment for gas cylinder leakage. When the device is in use, the gas cylinder is placed in the gas cylinder rack 2, and the elastic clamping springs 23 are used to fix and clamp the gas cylinder to ensure the stable use of the gas cylinder. At the same time, the height of the regulating rod 5 is adjusted so that the height of the sealing cover 4 matches the gas cylinder to ensure that the leaking gas cylinder can be quickly processed in case of an emergency.
