[0002] Negative pressure degassing device is a device used to remove gas molecules from substances, usually used in laboratories, production lines, etc. Its working principle is to reduce the air pressure so that the gas molecules in the substance are separated from the surface of the substance and sucked away to achieve the purpose of degassing.

[0003] However, in the prior art, in order to prevent the equipment from being directly disconnected from the ground and damaged after long-term use, some existing negative pressure degassing devices usually install a bottom plate frame at the bottom of the equipment to fix and isolate it from the ground. However, the bottom plate frame currently used is usually welded from multiple steel rods. Since the bottom plate frame is welded from multiple steel rods, it may bend, deform, etc. under load, thereby causing instability and damage to the equipment. At the same time, since the bottom plate frame is welded from multiple steel rods, if there is a problem and needs to be repaired or replaced, it needs to be cut and disassembled, which increases the difficulty of maintenance and causes unnecessary trouble. Utility Model Content

After the limit is good, the two connecting frames 16 can be fixed between the fixing members 17 and the load-bearing plate 11 by rotating the fixing members 17 in sequence. When the staff uses it, they can first start the vacuum 15. When the vacuum 15 is driven, its output shaft will extract the gas through the transmission pipe 14 to form a vacuum. During this process, the vacuum 15 will continue to work, so that the internal pressure of the vacuum tank 13 is continuously reduced until the required vacuum degree is reached. At the same time, through the structural design of the support frame 12 and the load-bearing plate 11, the stability of the equipment can be guaranteed, and it can withstand the pressure generated by the equipment during operation. Finally, through the connection between the surface of the vacuum tank 13 and the top of the support frame 12, leakage can be prevented during the air extraction process, thereby ensuring the air extraction efficiency and stability of the equipment.
