Description

Technical Field

[0001] This utility model relates to the field of X-ray detection, specifically a vacuum spin structure for a liquid sample platform in an X-ray detection instrument. Background Technology

[0002] In existing X-ray detection techniques, air in the optical path can affect the measurement of light elements in liquid samples, thus requiring vacuuming of the measurement chamber. Furthermore, due to varying viscosities of liquid samples, the distribution of substances within the liquid is uneven. If the measurement is performed while the sample is stationary, the uneven distribution within the liquid sample can easily lead to deviations in the detection results. Therefore, it is necessary to find a structure that can both create a vacuum and ensure uniform distribution of the liquid sample. Utility Model Content

[0003] In view of this, this case mainly addresses the need to overcome at least one of the aforementioned defects in the prior art when conducting X-ray inspection.

[0004] This invention provides a vacuum spin structure for a liquid sample platform in an X-ray detection instrument, comprising a vacuum chamber, a motor disposed outside the vacuum chamber, a small gear connected to the motor and extending into the vacuum chamber, a large gear meshing with the small gear, and the large gear and the sample placement platform being connected via a carrying bracket disposed inside a hollow cavity of a rotating shaft; the vacuum chamber includes a measuring chamber and an upper chamber, the upper chamber being located above the measuring chamber, the motor being mounted on the upper part of the measuring chamber and located outside the upper chamber, the motor extending into the upper chamber via a small gear shaft and connected to the small gear, the small gear meshing with the large gear, the sample placement platform being disposed inside the carrying bracket, and the carrying bracket and the rotating shaft being synchronously rotated in the rotational direction and connected to the rotating shaft by a piston rod dynamic seal.

[0005] According to the background technology of this patent, in static measurement, it is necessary to evacuate the measurement chamber. At the same time, the different viscosities of liquid samples can lead to uneven distribution inside the liquid sample, resulting in deviations in the detection results. The vacuum spin structure of the liquid sample platform in the X-ray detection instrument disclosed in this utility model uses a motor to drive a small gear to rotate. The small gear meshes with a large gear to rotate, which drives the rotating shaft to rotate, thereby driving the hand-held support and the sample placement platform to rotate, thus achieving spin. At the same time, the entire chamber is sealed through various sealing structures, and the vacuum function is achieved by installing a connector through the threaded hole of the measuring chamber pipe.

[0006] In addition, the vacuum spin structure of the liquid sample platform in the X-ray detection instrument disclosed in this utility model also has the following additional technical features:

[0008] Furthermore, a motor bracket for fixing the motor is provided on the top cover.

[0009] Furthermore, the pinion is a small bevel gear, and the large gear is a large bevel gear. The small bevel gear and the large bevel gear mesh perpendicularly through a central axis. The large gear and the pinion can be installed in a parallel shaft configuration or in a bevel gear configuration. Using a bevel gear configuration can make more efficient use of space, reduce volume, and create a more portable shape.

[0010] Furthermore, the rotating shaft is connected to the top cover via a bearing and a bearing bracket. A piston rod static seal is used between the top cover and the top of the bearing bracket. The bearing bracket and the bearing are tightly fitted together. The bearing and the rotating shaft are tightly fitted together. A piston rod dynamic seal is used between the rotating shaft and the bearing bracket.

[0011] Furthermore, a bearing cap is provided on the bearing bracket for pressing the bearing.

[0012] Furthermore, a bearing retaining ring is fixed on the rotating shaft to limit the bearing position.

[0013] Furthermore, the large gear is tightened and tightly fitted with the rotating shaft by a set screw.

[0014] Furthermore, the pinion shaft and the geared motor are connected by a coupling.
