Description

Technical Field

[0001] This utility model relates to the field of experimental equipment, specifically to a sample holder for an X-ray fluorescence spectrometer. Background Technology

[0002] X-ray fluorescence spectrometry (XRF) is frequently used in industry for the analysis of solid, liquid, and powdered samples. For bulk raw materials, powdered samples are typically cast into glass slides or directly pressed into slides. Regardless of the method, the slides must be placed in a sample cup, secured to the cup with a sample holder, and then placed in a specific position on the XRF analyzer, awaiting gripping by the robotic arm for analysis. Without proper securing, sample shifting during transfer and analysis can lead to distorted test results. Previously, manufacturer-installed metal screw locks were used for securing the slides; however, this method is complex, difficult to operate, unsuitable for low-cost testing, and inconvenient for staff. Utility Model Content

[0003] The purpose of this invention is to provide a sample holder for an X-ray fluorescence spectrometer.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an X-ray fluorescence spectrometer sample holder, including a handle, an extension body and a sample slot, wherein the extension body is a cylinder, the top surface of the extension body is provided with a handle, and the bottom surface of the extension body is provided with a sample slot.

[0005] Furthermore, the hand handle is located at the center of the top surface of the heightening body.

[0006] Furthermore, the sample slot is vertically located at the center of the bottom surface of the heightening body.

[0007] Furthermore, the handle includes a top surface and a side surface. The top surface is parallel to the horizontal plane, and the side surface is recessed towards the central axis of the handle, with the recess being arc-shaped.

[0008] Furthermore, the diameter of the sample slot in the sample holder is slightly smaller than the diameter of the sample, and the depth is slightly smaller than the thickness of the sample.

[0009] Furthermore, the hand handle is 15mm high and has a top diameter of 20mm.

[0010] Furthermore, the height of the augmenting body is 15mm and the diameter is 51mm.

[0011] Furthermore, the cross-section of the sample slot is circular, with a diameter of 38mm and a depth of 3mm.

[0012] Furthermore, chamfers are provided at the connection between the top surface of the hand handle and the side surface of the hand handle, the connection between the top surface of the heightening body and the side surface of the heightening body, and the connection between the side surface of the heightening body and the bottom surface of the heightening body.

[0013] Furthermore, the entire sample holder is made of ABS resin.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Improved operational efficiency: Traditional metal locks require rotation to tighten (taking 1-2 minutes), while this sample holder uses an inverted design, requiring only the sample cup to be flipped after placement to secure it, reducing operation time to 20-30 seconds and increasing efficiency by over 60%. Made of lightweight ABS resin (weighing only 18-22g), the ergonomic handle allows for easy one-handed operation, reducing labor intensity.

[0016] 2. Significantly reduced costs: The manufacturing cost of a single ABS resin component is 15-20 yuan, which is 85%-90% lower than that of metal buckles. ABS resin is wear-resistant and deformation-resistant. Experiments show that after one year of continuous use, the locking force retention rate is >95%, eliminating the need for frequent replacements and reducing annual maintenance costs by approximately 70%.

[0017] 3. Guaranteed detection accuracy: ABS resin has a low absorption rate of X-rays and does not contain any metal elements, thus avoiding the background noise caused by chromium and nickel in traditional locks. Attached Figure Description

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown, an X-ray fluorescence spectrometer sample holder is integrally injection molded from ABS resin, including a handle 1, a heightening body 2, and a sample slot 3. The heightening body 2 is a cylindrical structure, with the handle 1 vertically fixed at the center of its top surface, and the sample slot 3 vertically formed at the center of its bottom surface.

[0027] Specifically, the handle 1 includes a top surface 101 and a side surface 102. The top surface 101 is a circular plane parallel to the horizontal plane, with a diameter of 20mm. The side surface 102 is recessed towards the central axis, and the recess is arc-shaped, forming an ergonomic grip structure for easy one-handed operation. The total height of the handle 1 is 15mm, and a chamfer 4 with a radius of 1mm is provided at the connection between its top and side surfaces to prevent scratches to the user during operation and to prevent scratches on the inner wall of the X-ray fluorescence spectrometer sample cup.

[0028] The heightening body 2 is a cylinder with a diameter of 51mm and a height of 15mm. Chamfers 4, with a radius of 1mm, are provided at the junctions of its top and side surfaces, and at the junctions of its side surface and bottom surface. A sample slot 3 is formed at the center of the bottom surface of the heightening body 2. The slot has a circular cross-section with a diameter of 38mm and a depth of 3mm. The diameter of the sample slot 3 is slightly smaller than the diameter of the standard sample, and the depth is slightly smaller than the thickness of the sample. An interference fit is used to securely engage the sample.

[0029] During sample installation, hold the sample holder upside down and place the fused sample (not shown, analytical side up) into the sample holder's slot 3. Utilizing the elastic deformation properties of ABS resin, the sample edge is tightly secured by the sidewall of the slot. Then, place the bottom 5 of the X-ray fluorescence spectrometer's sample cup onto the sample holder from top to bottom. Next, flip the sample holder so that the handle 1 faces upwards and the sample holder 3 faces downwards. Fit the X-ray fluorescence spectrometer's sample cup wall 6 over the sample holder and secure it to the bottom 5. Finally, place the sample holder in the X-ray fluorescence spectrometer's detection position. Because ABS resin has low X-ray absorption and contains no metal components, interference with the detection signal is avoided.

[0030] In this embodiment, the total weight of the sample holder is 20g, significantly lighter than traditional metal locking structures. Furthermore, the abrasion resistance and deformation resistance of the ABS resin ensure that the locking force of the sample slot 3 remains above 95% even after long-term use.

[0031] The above embodiments are merely illustrative examples of the technical solutions of this utility model. Those skilled in the art can make adaptive adjustments to the dimensions, chamfer parameters, or materials according to actual needs, and such adjustments should all fall within the scope defined by the claims of this utility model.
