Description

Technical Field

[0001] This utility model relates to the field of soil sample testing with a spectrometer, and more particularly to a support device for soil sample testing with a spectrometer. Background Technology

[0002] A spectrometer is a scientific instrument that breaks down complex light into spectral lines. It consists of prisms or diffraction gratings and measures the light reflected from the surface of an object. By capturing light information with a spectrometer, developing it on photographic film, or displaying and analyzing the data using computerized automated instruments, the elements contained in an object can be determined. This technology is widely used in the detection of air pollution, water pollution, food hygiene, and in the metal industry.

[0003] XRF spectrometers can be used to test soil samples. However, the instruments themselves are relatively heavy, and prolonged handheld use can cause arm pain and shaking, reducing testing efficiency. Furthermore, the gap between the instrument and the sample during testing can affect the accuracy of the results. To address these issues, those skilled in the art have designed a support device for soil sample testing using a spectrometer. This device uses a screw to connect a placement ring for the XRF spectrometer, and rotating the screw moves the placement ring closer to or away from the soil sample, thus moving the XRF spectrometer closer to or further away from the sample for soil sample analysis. However, this method of moving the XRF spectrometer closer to or further away from the sample by rotating the screw results in low movement efficiency, further reducing the efficiency of soil sample testing. Therefore, a support device for soil sample testing using a spectrometer is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a support device for soil sample testing with a spectrometer, thereby solving the above-mentioned problems.

[0005] To achieve this objective, the present invention adopts the following technical solution: A support device for spectrometer soil sample testing, comprising: Support platform; An elastic support assembly is disposed on the support platform, the elastic support assembly including an elastic support plate and a cushion disposed on one side of the elastic support plate; The transfer assembly includes a slide rail disposed on the support platform, a slide rod disposed on the slide rail, a mounting ring disposed at one end of the slide rod near the cushion, a spectrometer being mounted on the mounting ring, and a plurality of limiting teeth disposed on one side of the slide rod, one side of the limiting teeth being an inclined surface; A limiter is disposed on the support platform, and the limiter includes an elastic limit plate corresponding to the limit tooth.

[0006] Optionally, the elastic support assembly further includes a first upright plate disposed on the support platform, the first upright plate being connected to the elastic support plate via a first spring.

[0007] Optionally, the elastic support assembly further includes a first telescopic rod, which is sleeved inside the first spring, with one end of the first telescopic rod connected to the first upright plate and the other end connected to the elastic support plate.

[0008] Optionally, the limiter is mounted on the support platform via a mounting base; The limiter includes a housing, a first through hole on one side of the housing for the elastic limiting plate to pass through, a sliding plate and a second spring connected at one end to the sliding plate inside the housing, the other end of the second spring being connected to the inner wall of the housing, and the elastic limiting plate being disposed on one side of the sliding plate.

[0009] Optionally, a second telescopic rod is also provided inside the housing. The second telescopic rod is sleeved inside the second spring. One end of the second telescopic rod is connected to the inner wall of the housing, and the other end is connected to the sliding plate.

[0010] Optionally, a pull rod is provided on the side of the slide away from the elastic limiting plate. The pull rod passes through the housing and extends outside the housing, and a pull ring is provided at one end of the pull rod.

[0011] Optionally, a reset assembly is provided on the side of the slide rod away from the limiter. The reset assembly includes a second upright plate disposed on the support platform and an extension plate disposed on one side of the slide rod. The second upright plate and the extension plate are connected by a third spring.

[0012] Optionally, the reset assembly further includes a third telescopic rod, which is sleeved inside the third spring. One end of the third telescopic rod is connected to the second upright plate, and the other end is connected to the outer extension plate.

[0013] Optionally, a push ring is provided at the end of the slide rod away from the mounting ring; The support platform is provided with a second through hole for the spectrometer to pass through, and a support column is provided on the bottom surface of the support platform.

[0014] Compared with existing technologies, this invention has the following advantages: During testing, the spectrometer is mounted on the mounting ring, and the soil sample is placed on the support platform. Then, the operator pushes the sliding rod, causing it to move along the slide rail towards the elastic support plate. This causes the mounting ring and the spectrometer to move, with the inner end of the spectrometer pressing against the soil sample and continuing to move. When the other end of the soil sample is pressed against the pad and continues to move, the elastic support plate generates a spring force on the pad. This spring force acts on the sliding rod through the soil sample, the spectrometer, and the mounting ring, causing the sliding rod to tend to move away from the elastic support plate. At this time, the elastic limiting plate engages with the limiting teeth, preventing the sliding rod from moving away from the elastic support plate. Simultaneously, the inner end of the spectrometer presses against the soil sample and tests it, effectively avoiding gaps between the spectrometer and the soil sample during testing and improving testing accuracy. Furthermore, by pushing the sliding rod, the spectrometer moves rapidly towards the soil sample, greatly improving the efficiency of soil sample testing. Attached Figure Description

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1 to 4This utility model provides a support device for soil sample testing using a spectrometer 100, including a support platform 10, an elastic support assembly 20, a transfer assembly 30, and a limiter 40. The support platform 10 has a rectangular surface, and the elastic support assembly 20 is disposed on the support platform 10 and located at one end of the surface. The elastic support assembly 20 includes an elastic support plate 21 and a cushion 22 disposed on one side of the elastic support plate 21. The cushion 22 is made of a soft material. The cushion 22 is used to protect and support the soil sample carrier. By using a soft material, it can prevent the elastic support plate 21 from damaging the soil sample, thereby ensuring the reliable operation of the testing device. The transfer assembly 30 includes a slide rail 31 disposed on the support platform 10, and a slide rod 32 is disposed on the slide rail 31. The slide rod 32 can slide on the slide rail 31, and the sliding direction of the slide rod 32 is perpendicular to the plane where the elastic support plate 21 is located. A mounting ring 33 is provided at one end of the slide rod 32 near the cushion 22. The spectrometer 100 is mounted on the mounting ring 33. When the slide rod 32 is slidable, the slide rod 32 drives the mounting ring 33 and the spectrometer 100 to move towards or away from the elastic support plate 21. A plurality of limiting teeth 34 are provided on one side of the slide rod 32, and the side of the limiting teeth 34 near the cushion 22 is inclined. It should be noted that the slide rod 32 in this embodiment of the present invention is a square rod, that is, the cross-section of the slide rod 32 is square. The limiting teeth 34 are provided on one side surface of the slide rod 32. The limiter 40 is provided on the support platform 10. The limiter 40 includes an elastic limiting plate 41 corresponding to the limiting teeth 34. When the slide rod 32 moves towards the elastic support plate 21 and is subjected to the elastic force of the elastic support plate 21, the elastic limiting plate 41 is engaged with the limiting teeth 34 to prevent the slide rod 32 from moving away from the elastic support plate 21.

[0023] Specifically, during the test, the spectrometer 100 is mounted on the mounting ring 33, and the soil sample is placed on the support platform 10. Then, the operator pushes the slide bar 32, causing it to move along the slide rail 31 towards the elastic support plate 21. This causes the slide bar 32 to move the mounting ring 33 and the spectrometer 100. The inner end of the spectrometer 100 presses against the soil sample and continues to move. When the other end of the soil sample is pressed against the pad 22 and continues to move, the elastic support plate 21 generates an elastic force on the pad 22. This elastic force acts on the slide bar 32 through the soil sample, the spectrometer 100, and the mounting ring 33, causing the slide bar 32 to tend to move away from the elastic support plate 21. At this time, the elastic limiting plate 41 is engaged with the limiting tooth 34 to prevent the slide bar 32 from moving away from the elastic support plate 21. At this time, the inner end of the spectrometer 100 presses against the soil sample and tests the soil sample, effectively avoiding the gap between the spectrometer 100 and the soil sample during the test and improving the test accuracy; at the same time, by pushing the slide bar 32, the spectrometer 100 is moved quickly towards the soil sample, which greatly improves the efficiency of soil sample testing.

[0024] Furthermore, the elastic support assembly 20 also includes a first upright plate 23 fixedly mounted on the support platform 10. The first upright plate 23 is connected to the elastic support plate 21 via a first spring 24. In this embodiment of the invention, there are four first springs 24, the first upright plate 23 is rectangular, and the first springs 24 are located at the four corners of the first upright plate 23, thereby improving the stability of the elastic support plate 21.

[0025] Furthermore, the elastic support assembly 20 also includes a first telescopic rod 25, which is sleeved within the first spring 24. One end of the first telescopic rod 25 is connected to the first upright plate 23, and the other end is connected to the elastic support plate 21. This technical solution ensures that the elastic support plate 21 remains parallel to the first upright plate 23 as it moves closer to or further away from it.

[0026] Furthermore, the limiter 40 is mounted on the support platform 10 via the mounting base 50. The limiter 40 includes a housing 42, one side of which has a first through hole for the elastic limiter plate 41 to pass through. It should be noted that the side of the housing 42 where the first through hole is located is parallel to the side of the slide rod 32. Inside the housing 42, there is a slide plate 43 and a second spring 44, one end of which is connected to the slide plate 43. The other end of the second spring 44 is connected to the inner wall of the housing 42. The elastic limiter plate 41 is disposed on one side of the slide plate 43. With this technical solution, the elastic limiter plate 41 can extend out of the housing 42 through the first through hole, or it can retract into the housing 42 through the first through hole. When the elastic limiter plate 41 extends out of the housing 42 through the first through hole, the elastic limiter plate 41 can be engaged with the limiter tooth 34. Specifically, when the operator pushes the slide rod 32 to move closer to the elastic support plate 21, the inclined surface of the limiting tooth 34 presses against the elastic limiting plate 41, causing the elastic limiting plate 41 to contract, thus allowing the slide rod 32 to continue moving closer to the elastic support plate 21. When the elastic support plate 21 exerts a spring force on the slide rod 32, causing the slide rod 32 to tend to move away from the elastic support plate 21, the elastic limiting plate 41 engages with the limiting tooth 34, preventing the slide rod 32 from moving away from the elastic support plate 21. It should be noted that the second spring 44 in this embodiment is always in a compressed state, so that one end of the elastic limiting plate 41 is always in contact with the limiting tooth 34.

[0027] Furthermore, a second telescopic rod 45 is also provided inside the housing 42. The second telescopic rod 45 is sleeved inside the second spring 44. One end of the second telescopic rod 45 is connected to the inner wall of the housing 42, and the other end is connected to the slide plate 43. In this embodiment of the present invention, there are two second springs 44, and correspondingly, there are also two second telescopic rods 45, so that the slide plate 43 remains parallel to the inner wall surface of the housing 42 during movement.

[0028] Furthermore, a pull rod 46 is provided on the side of the slide plate 43 away from the elastic limiting plate 41, and a third through hole is provided on the side wall of the housing 42 away from the first through hole. The pull rod 46 passes through the third through hole and extends to the outside of the housing 42, and a pull ring 47 is provided at one end of the pull rod 46. When it is necessary to release the limiting tooth 34 by the elastic limiting plate 41, the pull rod 46 is pulled by the pull ring 47, thereby pulling the slide plate 43, causing the elastic limiting plate 41 to move away from the slide rod 32, so that the elastic limiting plate 41 disengages from the limiting tooth 34. At this time, the slide rod 32 can move away from the elastic support plate 21.

[0029] Furthermore, a reset assembly 60 is provided on the side of the slide rod 32 away from the limiter 40. The reset assembly 60 includes a second upright plate 61 disposed on the support platform 10 and an extension plate 62 disposed on one side of the slide rod 32. The second upright plate 61 and the extension plate 62 are connected by a third spring 63. When the operator pushes the slide rod 32, causing it to move along the slide rail 31 in a direction close to the elastic support plate 21, and the inner end of the spectrometer 100 presses against the soil sample, while the other end of the soil sample is pressed against the pad 22, the third spring 63 is in a compressed state. After the soil test is completed, the operator pulls the pull ring 47, causing the elastic limit plate 41 to disengage from the limit tooth 34. Under the elastic force of the third spring 63, the slide rod 32 moves away from the elastic support plate 21 until the spectrometer 100 separates from the soil sample, so that the operator can remove the soil sample.

[0030] Furthermore, the reset assembly 60 also includes a third telescopic rod 64, which is sleeved within the third spring 63. One end of the third telescopic rod 64 is connected to the second vertical plate 61, and the other end is connected to the outer extension plate 62. This technical solution avoids bending of the third spring 63 when it is compressed, thus improving the stability of the reset assembly 60.

[0031] Furthermore, a push ring 35 is provided at the end of the slide rod 32 away from the mounting ring 33, so that the operator can push the slide rod 32. The support platform 10 is provided with a second through hole 11 for the spectrometer 100 to pass through, and a support column 12 is provided on the bottom surface of the support platform 10.

[0032] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
