Description

Technical Field

[0001] The utility model belongs to the technical field of design and manufacture of isotope magnetic mass spectrometers in analytical instruments, and specifically relates to a support column for a mass spectrometer system. Background Art

[0002] There are many factors that need to be considered when designing a mass spectrometer. Generally, due to the limited distance between the ion source outlet slit and the edge of the magnet, it is impossible to effectively design the mechanical support. If a hard connection is used, it is impossible to ensure that the final installation position meets the design conditions. If you want to make adjustments, you need to add a bellows to connect the ion source cavity and the flight flat tube, but the distance is not enough to install multiple flange connections. Utility Model Content

[0003] In order to solve the above problems in the prior art, namely, the hard connection between the ion source cavity and the flying flat tube of the existing thermal ionization mass spectrometer makes it impossible to adjust, and the subsequent installation of the bellows is too long but the distance is limited to make it impossible to effectively install, the utility model provides a mass spectrometer system support column.

[0004] The present application provides a mass spectrometer system support column, which adopts the following technical solution:

[0005] A mass spectrometer system support column, comprising a support member, a bellows and a flange;

[0006] The support member includes a support block and a support plate, the support plate supports the support block, and a connecting hole is formed through the support block;

[0007] One end of the bellows is inserted into the connecting hole and fixedly connected to the supporting block, and the other end is fixedly connected to the flange.

[0008] By adopting the above technical solution, when in use, the flange is connected to the ion source cavity of the thermal ionization mass spectrometer, and the bellows is connected to the ion source cavity of the thermal ionization mass spectrometer by installing screws. The problem of no space for installing two flanges of the bellows connected separately is solved through one-piece welding. The three parts are processed separately and welded together, and the flange is cleverly designed on the support column. The design is clever, space-saving, and easy to install.

[0009] Then, when installing a longer corrugated pipe, multiple support columns are connected together to increase the length of the overall corrugated pipe, and when two adjacent support columns are connected together, the flange of the corrugated pipe is connected to the support block. When multiple support columns are connected together, the arrangement height of the corrugated pipe is the same.

[0010] Preferably, the flange is provided with a plurality of cutouts in the circumferential direction, and the plurality of cutouts are arranged at equal intervals in the circumferential direction of the flange.

[0011] By adopting the above technical solution and the design of the cutout, the problem that the screws cannot be installed is solved.

[0012] Preferably, a plurality of connecting screw holes are opened in the circumference of the connecting hole, and the plurality of connecting screw holes are arranged at equal intervals; and the incision is aligned with the connecting screw holes.

[0013] Preferably, the incision is U-shaped.

[0014] By adopting the above technical solution, it is convenient to set the incision.

[0015] Preferably, a base is fixedly connected to the lower side of the support plate, and a plurality of mounting holes are formed through the base.

[0016] By adopting the above technical solution, the base can be conveniently installed on the table.

[0017] Preferably, a reinforcing rib is fixedly connected between the support plate and the base.

[0018] Preferably, the base, support plate, support block and reinforcing ribs are integrally formed.

[0019] Beneficial effects of the utility model:

[0020] (1) Cut the six screw holes on the flange into U-shaped cutouts to facilitate the installation of the connecting screws.

[0021] (2) The overall design is compact and easy to install, which solves the problem of installation in small space.

[0022] (3) By connecting the bellows, the hard connection is changed to a soft connection, which greatly facilitates the installation, debugging and correction of the instrument. BRIEF DESCRIPTION OF THE DRAWINGS
