Description

Technical Field

[0001] This utility model relates to the field of spectrometer technology, and in particular to a spectrophotometer sample reflectance measurement bracket. Background Technology

[0002] A spectrophotometer, also known as a spectrometer, is a scientific instrument that breaks down complex light into spectral lines. Its measurement range generally includes the visible light region (380-780 nm) and the ultraviolet light region (200-380 nm). Different light sources have their own unique emission spectra, therefore different light sources can be used as the instrument's light source. The emission spectrum of a tungsten lamp: The 380-780 nm wavelength spectral light emitted by a tungsten lamp, after being refracted by a prism, yields a continuous chromatogram composed of red, orange, yellow, green, blue, indigo, and violet; this chromatogram can be used as the light source for a visible light spectrophotometer. When measuring the reflectance spectrum of a sample with an infrared spectrophotometer, the standard reflectance accessory can only measure samples smaller than 100x100 mm. Since some users need to test samples of 300x300 mm or even larger, this limitation restricts its application.

[0003] Patent CN214668526U discloses a large sample reflectance measurement bracket for a spectrophotometer, comprising: a standard reflectance accessory, disposed at the top left side of the sample chamber floor and used to support and place the sample to be measured; and a large sample bracket, disposed at the top right side of the sample chamber floor and used to support and place a larger sample to be measured.

[0004] The aforementioned patents still have the following technical defects: although the large sample support can meet the support requirements for large samples, its support structure is inconvenient to disassemble, resulting in a large overall space occupied by the equipment. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a spectrophotometer sample reflectance measurement bracket.

[0023] Example 1

[0024] like Figures 1-4 As shown in the figure, the spectrophotometer sample reflectance measurement bracket proposed in this embodiment includes at least three support frame mechanisms. Each support frame mechanism includes a rotating support rod 1 and a telescopic rod assembly. The rotating support rod 1 is rotatably mounted on the top periphery of the spectrophotometer body 11. The telescopic rod assembly is rotatably mounted on the rotating support rod 1 at one end away from the spectrophotometer body 11. Furthermore, after the rotating support rod 1 is rotated to be perpendicular to the spectrophotometer body 11, the upper end surface of the rotating support rod 1 is higher than the detection surface at the top of the spectrophotometer body 11. In this way, the weight of the sample is distributed among multiple support frame mechanisms, and no pressure is applied to the upper end of the spectrophotometer body 11, thereby reducing the probability of damage to the spectrophotometer body 11.

[0025] A positioning rod 8 is slidably connected to one side of the rotating support rod 1 adjacent to the telescopic rod assembly. A base 111 is provided at the bottom of the spectrophotometer body 11. The base 111 has multiple positioning slots 1111 for the insertion of the rod 8. When folding the support frame mechanism, the telescopic rod assembly is first retracted to its shortest length. Then, the telescopic rod assembly is driven to rotate and make it parallel to the rotating support rod 1. Then, the rotating support rod 1 is driven to rotate downward and make it vertical. During this process, the positioning rod 8 should be held down. When the rotating support rod 1 is vertical, the positioning rod 8 slides downward due to gravity and its bottom end is inserted into the positioning slot 1111, thereby completing the limiting work of the folded support frame mechanism.

[0026] The rotating support rod 1 has a fitting groove 101 along its length for accommodating the telescopic rod assembly. The fitting groove 101 can be used to store the folded telescopic rod assembly, thereby further reducing the space occupied by the support frame mechanism.

[0027] The spectrophotometer sample reflectance measurement bracket also includes a partition 9. The upper end of the spectrophotometer body 11 has a probe hole 1101. The side of the spectrophotometer body 11 has a slot 1102 for inserting the partition 9. The slot 1102 communicates with the probe hole 1101. After the partition 9 is inserted into the defined position inside the slot 1102, the partition 9 completely covers the probe hole 1101.

[0028] Multiple rotating support rods 1 are equipped with clamping components. Each clamping component includes a clamping block 4, a fixed seat 5, a threaded rod 6, and a knob 7. The fixed seat 5 is mounted on the rotating support rod 1. The threaded rod 6 is threadedly connected to the fixed seat 5. The clamping block 4 and the knob 7 are respectively mounted on both ends of the threaded rod 6. A guide rod 10 is connected to the clamping block 4. The guide rod 10 moves through the fixed seat 5.

[0029] Before placing the sample, insert the partition 9 into the inside of the slot 1102, then place the sample in the detection area at the top of the spectrophotometer body 11, and drive the multiple clamping blocks 4 to move to clamp and fix the sample. Then, pull the partition 9 out from the inside of the slot 1102, and finally turn on the machine to perform the detection. The above structure is designed to prevent samples with sharp corners from scratching the lens, thus protecting the lens. Secondly, when not in use, the partition 9 covers the probe hole 1101, thereby preventing dust from accumulating on the lens surface and ensuring that the detection accuracy is not affected by dust.

[0030] Specifically, in this technical solution, after unfolding multiple support frame mechanisms, multiple rotating support rods 1 can form a horizontal support structure, which can support large samples, making it possible for the instrument to detect large-sized samples. Furthermore, multiple support frame mechanisms can be folded and retracted one by one, and the space occupied after folding is small. In summary, this technical solution can overcome the instrument's detection requirements for small-sized samples and meet the detection requirements for large-sized samples. Moreover, the support frame mechanisms can be easily folded and unfolded, and have the advantages of simplified structure and strong applicability.

[0031] Example 2

[0032] like Figure 3 As shown in the figure, the spectrophotometer sample reflectance measurement bracket proposed in this embodiment has the following features compared to Embodiment 1: the telescopic rod assembly includes a sleeve 2 and a movable support leg 3. The sleeve 2 and the rotating support rod 1 have a rotatable connection structure. The end of the movable support leg 3 is slidably installed on the inner side of the sleeve 2. A wing bolt 12 is threaded onto the sleeve 2. A limit groove is provided on the movable support leg 3. The telescopic rod assembly is designed to facilitate folding and storage.

[0033] Example 3

[0034] like Figure 3 and Figure 4As shown in this embodiment, a spectrophotometer sample reflectance measurement bracket is proposed. Compared with the first embodiment, in this embodiment, a T-shaped limiting block 13 is provided at one end of the rotating support rod 1 near the telescopic rod assembly. A T-shaped hole 102 is provided on the rotating support rod 1 for the T-shaped limiting block 13 to be inserted. A limiting hole 201 is provided on the sleeve 2 near its rotating shaft end. After the support frame mechanism is fully extended, the T-shaped limiting block 13 is inserted into the T-shaped hole 102. At this time, the T-shaped limiting block 13 contacts the side wall of the sleeve 2, which can limit the sleeve 2. Furthermore, a limiting block should be provided at the end of the rotating support rod 1. The limiting block is used to limit the rotation of the telescopic rod assembly, so that the maximum rotation angle of the telescopic rod assembly is 90 degrees. With the T-shaped limiting block 13, the sleeve 2 and the rotating support rod 1 always remain perpendicular.

[0035] The spectrophotometer body 11 has multiple circular slots 1103 for inserting multiple wing bolts 12. When the support frame mechanism is folded, the wing bolts 12 are placed inside the circular slots 1103 on the corresponding side, so that the sleeve 2 can be set tightly against the outer wall of the spectrophotometer body 11, reducing the space occupied.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
