Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically to a sample tube fixing assembly for a nuclear magnetic resonance spectrometer used for traditional Chinese medicine detection. Background Technology

[0002] Nuclear magnetic resonance (NMR) spectroscopy (NMR) analysis of traditional Chinese medicine (TCM) involves analyzing the magnetic resonance signals of hydrogen or carbon atoms to obtain information about its chemical composition and structure. This technique utilizes the differences in resonance frequencies of atomic nuclei under different chemical environments to generate characteristic spectra, which are used to identify the authenticity of medicinal materials, assess quality, and study the material basis of their efficacy. For example, the carbon spectrum of ginsenosides can clearly show the carbon atom bonding patterns, providing a basis for TCM quality control. Currently, to ensure the stability of the sample tubes, sample tube fixing components are usually used to limit their position.

[0003] Sample tube fixing assemblies on the market usually lack automated auxiliary sample introduction mechanisms, have simple structures, lack automation functions, and have low operating efficiency. To address this, we propose a sample tube fixing assembly for a nuclear magnetic resonance spectrometer for the detection of traditional Chinese medicine. Utility Model Content

[0004] The purpose of this invention is to provide a sample tube fixing component for a nuclear magnetic resonance spectrometer used for the detection of traditional Chinese medicine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sample tube fixing assembly for a nuclear magnetic resonance spectrometer for traditional Chinese medicine detection, comprising a support base and a sample injection assembly. The support base is an integrated structure, and a fixing seat is provided on the upper side of the support base. The bottom of the fixing seat is tightly connected to the upper surface of the support base. A receiving groove is provided on the upper surface of the fixing seat. The sample injection assembly is disposed inside the fixing seat and includes a receiving cavity, a dustproof heat dissipation port, a stepper motor, a support column, an electric telescopic rod, and a support groove. The receiving cavity is located at the lower end inside the fixing seat, and a dustproof heat dissipation port is provided on the side surface of the receiving cavity. A stepper motor is provided on the upper side inside the receiving cavity, and the output end of the stepper motor is connected to the support column through a coupling.

[0006] Furthermore, an electric telescopic rod is installed on the upper right end of the accommodating cavity, and a support groove is provided on the top of the electric telescopic rod.

[0007] Furthermore, a magnetic layer is provided on the inner surface of the support groove, and the lower surface of the support groove is tightly connected to the top of the electric telescopic rod.

[0008] Furthermore, an arc-shaped protective plate is installed on the upper left side of the fixed base, and the arc-shaped protective plate is made of transparent acrylic sheet material.

[0009] Furthermore, the surface of the support column is provided with a limiting component for limiting and fixing the sample tube, and the limiting component includes a limiting support plate, a limiting support hole, a sample tube limiting cylinder, a magnetic suction cup, a rubber elastic pad, and a limiting hole.

[0010] Furthermore, the limiting support plate is disposed on the upper surface of the support column, and the limiting support plate has a limiting support hole on its surface.

[0011] Furthermore, a sample tube limiting cylinder is slidably connected to the inner side of the limiting support hole, and a magnetic chuck is provided at the bottom of the sample tube limiting cylinder.

[0012] Furthermore, a rubber elastic pad is provided inside the sample tube limiting cylinder, and a limiting hole is formed on the surface of the rubber elastic pad.

[0013] This utility model provides a sample tube fixing component for a nuclear magnetic resonance spectrometer for the detection of traditional Chinese medicine, which has the following beneficial effects:

[0014] 1. This utility model, by setting up a sample injection component, includes a accommodating cavity, a dustproof heat dissipation port, a stepper motor, a support column, an electric telescopic rod, and a support groove. In use, the accommodating cavity is the internal space that houses the core components of the auxiliary sample injection mechanism. Activating the stepper motor causes the support column to rotate, which in turn rotates the sample tube limiting cylinder on the limiting support plate to above the support groove. Activating the electric telescopic rod causes the support groove to move upwards until the magnetic layer inside the support groove magnetically connects with the magnetic chuck on the lower side of the sample tube limiting cylinder. The support groove then lifts the sample tube limiting cylinder for auxiliary sample injection. Thus, through the coordinated action of the stepper motor and the electric telescopic rod, this device achieves precise positioning of the sample tube, automates auxiliary sample injection, and significantly improves detection efficiency.

[0015] 2. This utility model incorporates a limiting component, which includes a limiting support plate, a limiting support hole, a sample tube limiting cylinder, a magnetic chuck, a rubber elastic pad, and a limiting hole. In use, the sample tube is inserted into the limiting hole on the surface of the rubber elastic pad in the sample tube limiting cylinder. Due to the elasticity of the rubber elastic pad, the limiting hole can expand according to the diameter of the sample tube to accommodate limiting sample tubes of different diameters. The sample tube is stably limited by the equidistantly spaced rubber elastic pads. The sample tube limiting cylinder is positioned on the limiting support plate by the engaging connection between the sample tube limiting cylinder and the inner side of the limiting support hole. This allows the device to stably limit the sample tube and is adaptable to sample tubes of different diameters. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 4 As shown, a sample tube fixing assembly for a nuclear magnetic resonance spectrometer used for traditional Chinese medicine detection includes a support base 1 and a sample injection assembly 4. The support base 1 is an integrated structure, and a fixing seat 2 is provided on the upper side of the support base 1. The bottom of the fixing seat 2 is tightly connected to the upper surface of the support base 1. A receiving groove 3 is formed on the upper surface of the fixing seat 2. The sample injection assembly 4 is disposed inside the fixing seat 2 and includes a receiving cavity 401, a dustproof heat dissipation port 402, a stepper motor 403, a support column 404, an electric telescopic rod 405, and a support groove 406. The cavity 401 is located at the lower end of the fixed base 2, and a dustproof heat dissipation vent 402 is provided on the side surface of the cavity 401. A stepper motor 403 is provided on the upper side of the cavity 401, and the output end of the stepper motor 403 is connected to a support column 404 through a coupling. An electric telescopic rod 405 is installed on the upper right end of the cavity 401, and a support groove 406 is provided on the top of the electric telescopic rod 405. A magnetic layer is provided on the inner surface of the support groove 406, and the lower surface of the support groove 406 is tightly connected to the top of the electric telescopic rod 405.

[0023] The specific operation is as follows: During use, the accommodating cavity 401 is the internal space that accommodates the core components of the auxiliary sample injection mechanism. The stepper motor 403 is started, which drives the support column 404 to rotate. The support column 404 drives the sample tube limiting cylinder 603 on the limiting support plate 601 to rotate above the support groove 406. The electric telescopic rod 405 is started, which drives the support groove 406 to move upward until the magnetic layer inside the support groove 406 is magnetically connected to the magnetic chuck 604 on the lower side of the sample tube limiting cylinder 603. The support groove 406 then lifts the sample tube limiting cylinder 603 to perform auxiliary sample injection.

[0024] Please refer to Figures 3 to 4 An arc-shaped protective plate 5 is installed on the upper left side of the fixed base 2. The arc-shaped protective plate 5 is made of transparent acrylic sheet material. The surface of the support column 404 is provided with a limiting component 6 for limiting and fixing the sample tube. The limiting component 6 includes a limiting support plate 601, a limiting support hole 602, a sample tube limiting cylinder 603, a magnetic suction cup 604, a rubber elastic pad 605, and a limiting hole 606. The limiting support plate 601 is located on the upper surface of the support column 404. The limiting support plate 601 has a limiting support hole 602 on its surface. The sample tube limiting cylinder 603 is slidably connected to the inner side of the limiting support hole 602. The sample tube limiting cylinder 603 has a magnetic suction cup 604 at its bottom. The sample tube limiting cylinder 603 has a rubber elastic pad 605 on its inner side. The rubber elastic pad 605 has a limiting hole 606 on its surface.

[0025] The specific operation is as follows: When in use, insert the sample tube into the limiting hole 606 on the surface of the rubber elastic pad 605 in the sample tube limiting cylinder 603. Due to the elasticity of the rubber elastic pad 605, the limiting hole 606 can expand according to the diameter of the sample tube to accommodate the limiting of sample tubes of different diameters. The sample tube is stably limited by the equidistant rubber elastic pads 605. The sample tube limiting cylinder 603 is set on the limiting support plate 601 by the snap-fit ​​connection between the sample tube limiting cylinder 603 and the inner side of the limiting support hole 602.

[0026] In summary, as Figures 1 to 4As shown, the sample tube fixing assembly for the nuclear magnetic resonance spectrometer used for traditional Chinese medicine detection is used as follows: First, the sample tube is inserted into the limiting hole 606 on the surface of the rubber elastic pad 605 in the sample tube limiting cylinder 603. Due to the elasticity of the rubber elastic pad 605, the limiting hole 606 can expand according to the diameter of the sample tube to accommodate sample tubes of different diameters. The sample tube is stably limited by the equidistantly spaced rubber elastic pads 605. The sample tube limiting cylinder 603 is then set on the limiting support plate 601 by the engaging connection between the sample tube limiting cylinder 603 and the limiting support hole 602. The cavity 401 is the internal space that houses the core components of the auxiliary sample injection mechanism. The stepper motor 403 is started, causing the support column 404 to rotate. The support column 404 drives the sample tube limiting cylinder 603 on the limiting support plate 601 to rotate above the support groove 406. The electric telescopic rod 405 is started, causing the support groove 406 to move upward until the magnetic layer inside the support groove 406 is magnetically connected to the magnetic chuck 604 on the lower side of the sample tube limiting cylinder 603. The support groove 406 then lifts the sample tube limiting cylinder 603 for auxiliary sample injection.
