Description

Technical Field

[0001] This utility model relates to the field of elemental analysis equipment technology, and in particular to a portable XRF sample detection device. Background Technology

[0002] The analytical principle of XRF sample detection devices is as follows: a light source emits primary X-rays, which irradiate the sample. The atoms of the element to be measured absorb the corresponding energy to form an excited state, and the outer electrons transition to lower energy levels, simultaneously emitting secondary X-rays, i.e., X-ray fluorescence, to release energy. The intensity of the X-ray fluorescence is detected by a detector, thereby determining the content of the element to be measured. Portable XRF sample detection devices include handheld XRF sample detection devices.

[0003] However, in the existing technology, it has been found that some portable XRF sample inspection devices do not have protective measures for their inspection lenses and screens, which may result in the inspection lenses and screens being accidentally scratched when the portable XRF sample inspection device is not in use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-9 This utility model provides a technical solution: a portable XRF sample detection device, comprising: an XRF sample detector body 1, a connecting ear 101 fixedly connected to one end of the bottom of the XRF sample detector body 1, a protective groove 102 opened at one end of the XRF sample detector body 1, a detection lens 103 fixedly embedded and connected inside the protective groove 102, mounting grooves 104 opened on both sides of one end of the XRF sample detector body 1, a second protective groove 105 opened at the other end of the XRF sample detector body 1, a screen 106 fixedly embedded and connected inside the second protective groove 105, a protective plate moving groove 107 opened at one end of the top of the XRF sample detector body 1, the protective plate moving groove 107 communicating with the interior of the second protective groove 105, mounting grooves 108 opened at both ends of both sides of the inner cavity of the protective plate moving groove 107, a lens protection component 2 provided on the surface of one end of the XRF sample detector body 1, and a screen protection component 3 provided inside the protective plate moving groove 107.

[0028] Specifically: After the test is completed, the protective cover 201 is reattached to the surface of one end of the XRF sample detector body 1, and the lever 303 is pulled down so that the protective plate 301 covers the screen 106. This design of the portable XRF sample detector protects the detection lens 103 and the screen 106, preventing accidental scratches when the portable XRF sample detector is not in use. The opening of the protective groove 102 ensures that after the protective cover 201 is attached to the surface of one end of 1, there is still a certain gap between the detection lens 103 and the inner end of the protective cover 201, preventing the detection lens 103 from contacting the protective cover 201 and causing wear to the detection lens 103. There is also a certain gap between the installation of the screen 106 and the protective plate 301, preventing the protective plate 301 from contacting the screen 106 and causing wear to the screen 106. The XRF sample detector body 1 is usually designed to be handheld for easy carrying by the testing personnel.

[0029] In one embodiment, the lens protection assembly 2 includes a protective cover 201, a connecting ear 202 fixedly connected to the bottom of the protective cover 201, a connecting rope 203 wound around the inside of the connecting ear 202, and arc-shaped grooves 204 on both sides of the inner cavity of the protective cover 201, with a limiting ball 205 movably embedded inside each of the two arc-shaped grooves 204.

[0030] Specifically: The protective cover 201 and the XRF sample detector body 1 are connected by the connecting rope 203 to prevent the testing personnel from placing the protective cover 201 anywhere after it is removed, which could lead to the accidental loss of the protective cover 201.

[0031] In one embodiment, a T-shaped moving rod 206 is fixedly connected to one side of the arc-shaped surface of each of the two limiting balls 205. A sleeve 207 is movably sleeved on the other end of each of the two T-shaped moving rods 206. The two T-shaped moving rods 206 and the two sleeves 207 are paired together. Springs 208 are movably sleeved on the surfaces of the two pairs of T-shaped moving rods 206 and sleeves 207. One end of each spring 208 is fixedly connected to the arc-shaped surface of the two limiting balls 205. The other end of each sleeve 207 is fixedly connected to one side of the interior of the two mounting grooves 104. The other end of each spring 208 is fixedly connected to one side of the interior of the two mounting grooves 104.

[0032] Specifically: One end of the T-shaped moving rod 206 is movably embedded inside the sleeve 207. The diameter of one end of the T-shaped moving rod 206 is smaller than the diameter of the inner cavity of the sleeve 207 but larger than the diameter of the opening of the sleeve 207. This limits the movement of the T-shaped moving rod 206, ensuring that the limiting ball 205 is always mostly embedded inside the mounting groove 104, thus avoiding affecting the installation and removal of the protective cover 201.

[0033] In one embodiment, the screen protection component 3 includes a protective plate 301. Limiting blocks 302 are fixedly connected to the bottom of both sides of the protective plate 301. A bending block 303 is fixedly connected to one side of one of the limiting blocks 302. Arc-shaped grooves 304 are opened at both ends of the other two sides of the protective plate 301. Limiting balls 305 are movably embedded in the interior of the four arc-shaped grooves 304.

[0034] Specifically: the limiting block 302 limits the movement of the protective plate moving groove 107 inside the protective plate moving groove 107, preventing the protective plate 301 from detaching from the inside of the protective plate moving groove 107.

[0035] In one embodiment, a T-shaped moving rod 306 is fixedly connected to one side of the arc-shaped surface of each of the four limiting balls 305. A sleeve 307 is movably fitted onto the other end of each of the four T-shaped moving rods 306. The four T-shaped moving rods 306 and the four sleeves 307 are paired together. Springs 308 are movably fitted onto the surfaces of the four pairs of T-shaped moving rods 306 and sleeves 307. One end of each of the four springs 308 is fixedly connected to the arc-shaped surface of the four limiting balls 305. The other end of each of the four sleeves 307 is fixedly connected to one side of the interior of the four mounting grooves 108. The other end of each of the two springs 308 is fixedly connected to one side of the interior of the two mounting grooves 108.

[0036] Specifically: One end of the T-shaped moving rod 306 is movably embedded inside the sleeve 307. The diameter of one end of the T-shaped moving rod 306 is smaller than the diameter of the inner cavity of the sleeve 307 but larger than the diameter of the opening of the sleeve 307. This limits the movement of the T-shaped moving rod 306, ensuring that the limiting ball 305 is always partially embedded inside the mounting groove 108, thus avoiding affecting the up-and-down movement of the protective plate 301 and the limiting ball 305's limiting and fixing of the protective plate 301.

[0037] In one embodiment, the other end of the connecting rope 203 is wound around and connected to the inside of the connecting ear 101, the inside of the protective cover 201 is movably sleeved on the surface of one end of the XRF sample detector body 1, and the surfaces of the two limiting balls 205 are movably embedded in the inside of the two mounting slots 104.

[0038] Specifically: After the test is completed, the protective cover 201 is placed on the surface of one end of the XRF sample detector body 1 to prevent the detection lens 103 from being accidentally scratched when the portable XRF sample detection device is not in use.

[0039] In one embodiment, the surface of the protective plate 301 is movably embedded inside the protective plate moving groove 107, and the surfaces of the four limiting balls 305 are movably embedded inside the four mounting grooves 108.

[0040] Specifically: After the test is completed, cover the screen 106 with the protective plate 301 to prevent the screen 106 from being accidentally scratched when the portable XRF sample testing device is not in use.

[0041] Working principle: When this portable XRF sample testing device is needed to test the required material, the lever 303 is pulled upwards. The second limiting ball 305 moves into the mounting groove 108 under the pressure of the protective plate 301. The second spring 308 undergoes elastic deformation, and the second limiting ball 305 disengages from the inside of the arc-shaped groove 304. After the protective plate 301 loses the limiting ball 305, it moves upwards inside the protective plate moving groove 107. The two lower limiting balls 305, after losing the limiting of the protective plate 301, return to their original positions under the elastic force of the second spring 308. When the two arc-shaped grooves 304 below the protective plate 301 move to the position of the two upper limiting balls 305, the limiting balls 305 move into the arc-shaped groove 304 under the elastic force of the two upper springs 308 to fix the protective plate 301.

[0042] Hold the protective cover 201 and pull it outward from the XRF sample detector body 1. Under the pressure of the protective cover 201, the limiting ball 205 moves into the mounting groove 104. The spring 208 undergoes elastic deformation, and the limiting ball 205 disengages from the inside of the arc groove 204. After the protective cover 201 loses the limiting of the limiting ball 205, it can be removed from the surface of one end of the XRF sample detector body 1. Then, use this portable XRF sample detection device to detect the required material.

[0043] After the test is completed, put the protective cover 201 back on the surface of one end of the XRF sample detector body 1, and pull down the lever 303 so that the protective plate 301 covers the screen 106. This design of the portable XRF sample detection device can protect the detection lens 103 and the screen 106, and prevent the detection lens 103 and the screen 106 from being accidentally scratched when the portable XRF sample detection device is not in use.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
