Abstract

The invention relates to a mass spectrometry instrument, in particular to a buckling lock type rapid sealing device. The specific structure comprises a rapid sealing cavity, a buckling lock and a sealing ring. A sealing ring groove, the sealing ring and an assembly body needing to be sealed are arranged in the rapid sealing cavity in the installation sequence direction of the assembled mass spectrometer, and all the devices are of a flat plate structure with a middle through hole and are arranged in parallel, coaxially and insulatively. The four sides of the outer wall of the rapid sealing device are each provided with a buckling lock, so that it is guaranteed that the four sides of the rapid sealing device are evenly and coaxially stressed, the sealing characteristic is guaranteed, and meanwhile the manufacturing cost and dismounting time are saved. According to the novel buckling and pressing lock type rapid sealing device, the disassembly and assembly efficiency of a mass spectrometry instrument in daily work such as maintenance and overhaul is greatly improved, manpower, material resources and time are greatly saved while the sealing characteristic is guaranteed, and the buckling and pressing lock type rapid sealing device has wide application prospects in the field of analysis instruments used for environmental monitoring, food safety and medical diagnosis.

Description

technical field [0001] The invention relates to a mass spectrometer analysis instrument, in particular to a buckle lock type fast sealing device. The new buckle lock type quick sealing device technology greatly improves the efficiency of disassembly and assembly of mass spectrometer analysis instruments in daily work such as maintenance and repair, and greatly saves manpower, material resources and time while ensuring sealing characteristics. It has broad application prospects in the field of analytical instruments used by others. Background technique [0002] Mass spectrometry instruments are precision instruments in analytical chemistry. Analyzing sample substances in analytical chemistry requires mass spectrometry instruments to have high sensitivity and resolution. However, to improve the sensitivity and resolution of mass spectrometry instruments, not only When assembling, use high-precision assembly parts for reasonable matching, and at the same time, it is necessary ...
