Abstract
Description
Technical Field
[0001] This utility model relates to the field of analyzer technology, specifically a portable XRF analyzer. Background Technology
[0002] A handheld spectrometer is a spectroscopic analysis instrument based on XRF spectral analysis technology. When high-energy X-rays with energy higher than the binding energy of inner-shell electrons collide with an atom, they expel an inner-shell electron, creating a hole and making the entire atomic system unstable. When an outer-shell electron jumps to the hole, a primary photoelectron is generated. The ejected photon may be absorbed again, expelling another secondary photoelectron from the outer shell, resulting in the Auger effect, also known as the secondary photoelectric effect or non-radiative effect.
[0003] Authorization announcement number CN210982278U discloses a handheld XRF analyzer. This device mainly achieves a focused light effect when irradiating objects by using an irradiation tube in conjunction with a trapezoidal mirror, thus improving the accuracy of the test. This utility model also facilitates the maintenance of parts and improves the durability of the analyzer by using a rotating shaft in conjunction with a movable rod. However, the device still has the following drawbacks in actual use:
[0004] The aforementioned patent mainly achieves the effect of focusing light by setting a trapezoidal mirror, which improves the accuracy of the test. However, in actual use of XRF analyzers, the data analyzed is usually observed through the display screen. However, the display screen of the handheld analyzer is exposed and is easy to accidentally touch when not in use. It is also difficult to store and protect the display screen. In addition, the display screen does not have a recording function, making it difficult to manually record the analyzed data, which increases the limitations of the analyzer and reduces the detection efficiency.

[0030] Working principle: This portable XRF analyzer;
[0031] When using the XRF analyzer, by pulling the plug 34, the first spring 35 is elastically extended and retracted, canceling the positioning of the plug 34 and a set of slots 33. At this time, the sleeve 32 can be pulled out from the guide groove 31, thereby extending the handle length of the handle 2. After reaching the designated position, the pulling force of the plug 34 is released, and the elastic restoring force of the first spring 35 drives the plug 34 to reset and lock into another set of slots 33 for fixation. Thus, the extension of the sleeve 32 increases the grip length of the analyzer body 1, and the protective cover 38 can be opened to take out and put in the stored recording pen 37 as needed, increasing the structure's storage, carrying and length extension functions.
[0032] Pulling the lever 52 causes the second spring 53 to extend and retract elastically, causing the lever 52 to cause the locking plate 54 to disengage from the locking rack 56. At this time, the movable cover 4 can be opened, the trapezoidal seat 7 can be pulled out from the mounting slot 6, and the display and recording device 8 can be exposed. After reaching the designated position, the pulling force of the lever 52 is released, causing the lever 52 to drive the locking plate 54 to reset and re-engage with the locking rack 56 under the elastic restoring force of the second spring 53, so that the structure of the unfolded trapezoidal seat 7 is positioned. Then, the folding display screen 81 and the folding recording plate 82 are unfolded. The detector 9 in the analyzer body 1 performs the analyzer's detection work, and the data is observed through the folding display screen 81. The recording work is carried out in conjunction with the removed recording pen 37 and the folding recording plate 82, increasing the operability and convenience of the analyzer.
