Description

Technical Field

[0001] The utility model relates to the technical field of liquid oxygen storage, in particular to a fixing device for a liquid oxygen storage tank. Background Art

[0002] Liquid oxygen storage tanks usually use specially designed fixing devices to ensure their safety and stability. By using these fixing devices, the liquid oxygen storage tanks can be kept stable and safe during transportation, storage and use, reducing the occurrence of accidents;

[0003] After searching, the applicant discovered a Chinese patent disclosure for "A Fixing Device for Liquid Oxygen Storage Tanks" with publication number "CN219995071 U." This patent mainly uses a tank body clamp to fix liquid oxygen storage tanks of different sizes. The storage tank is placed inside a placement slot. The anti-slip strip provided inside the placement slot can prevent the storage tank from slipping. The knob is rotated to move the clamp adjustment threaded rod forward inside the clamp connection block, so that the tank body clamp can fix the storage tank. The provided balancing telescopic rod can prevent the tank body clamp from rotating on the clamp adjustment threaded rod. However, this device may be unable to move during the clamping process and the clamping may be unstable. To this end, we propose a fixing device for liquid oxygen storage tanks.
