Description

Technical Field

[0001] The invention relates to the technical field of photometers, in particular to an ultra-micro spectrophotometer and testing equipment thereof. Background Art

[0002] Ultra-micro spectrophotometer plays a vital role in biochemistry and molecular biology laboratories. This sophisticated instrument can accurately quantify biological macromolecules such as DNA, RNA and protein by measuring the absorbance of samples at specific wavelengths, thereby evaluating their concentration and purity. In order to achieve these high-precision measurements, ultra-micro spectrophotometers use high-brightness xenon lamps as light sources. Their spectral range covers a wide range of ultraviolet-visible regions, making the device suitable for a variety of biological samples. Ultra-micro spectrophotometers have become an indispensable research tool in modern laboratories due to their efficient and reliable performance. They are widely used in gene expression research, molecular diagnosis, biotechnology, drug development and other fields, providing strong support for scientific research and medical development.

[0003] When currently used, the existing ultra-micro spectrophotometer needs to be turned on and preheated first, and then the upper and lower bases are cleaned to ensure accurate measurement, followed by blank calibration to establish a measurement benchmark, and then 1-2μL of sample solution is moved to the base and measurement begins. The instrument will automatically complete the detection and display the results, and finally save and analyze the data, and further process it as needed. However, during the detection process, the device lacks a structure for shielding the light source of the detection equipment. When the sample is placed on the sample column for measurement, if the ambient light around the existing device is strong, it may affect the instrument's detection of the stability and accuracy of parameters such as sample concentration and absorbance. Although this open structure light source design simplifies the sample loading process, it may also cause the measurement results to be interfered with by external light, thereby affecting the accuracy and repeatability of the data. In view of this, we provide an ultra-micro spectrophotometer and its test equipment. Summary of the invention

[0009] As mentioned above, a rack is provided on the outer wall of the bottom end of the adjusting slider, and the center of the bottom surface of the adjusting slider is rotatably connected with the center of the top surface of the sliding gear through the meshing of the rack.

[0010] As mentioned above, a plurality of corresponding guide frames are fixedly connected on both sides of the inner wall of the photometer tester, and a lifting support is slidably connected to the inner center of the photometer tester through the guide frames, the light-shielding baffle is located on both sides of the top surface of the lifting support, and the outer wall of the bottom end of the light-shielding baffle is fixedly connected to one side of the top surface of the lifting support.

The first drive gear and the second drive gear are respectively located on both sides of the inside of the lifting support, and the two sides of the inner wall of the lifting support are rotatably connected to the outer walls of one side of the first drive gear and the second drive gear through gear meshing.

[0014] In addition, the present invention also provides a testing device, comprising the above-mentioned ultra-micro spectrophotometer.

[0015] Compared with the prior art, the ultra-micro spectrophotometer and its testing equipment have the following beneficial effects:

[0016] 1. In order to improve the protection and operation convenience of the photometer tester, the designer of the present invention has carefully designed a group of slide grooves on one side of the inner part of the lower base. These slide grooves are not only used to guide the movement of the adjustment slider, but also play a limiting role to ensure that the adjustment slider can only move horizontally along the direction of the slide groove during the movement. This design effectively prevents the adjustment slider from moving in an unexpected direction. A sliding gear is also provided on one side of the inner part of the lower base. The outer wall of one end of the sliding gear is fixed to the outer wall of one side of the protective baffle to form a rotation connection. When the device is no longer in use, the operator can push the adjustment slider along the inner wall of the slide groove. As the adjustment slider moves, the sliding gear is rotated. The protective baffle rotates by itself, driving the protective baffle to rotate with the sliding gear as the center. This rotational movement enables the protective baffle to fit tightly with the outer wall of one side of the test base, thereby effectively protecting the photometric camera, while avoiding the risk of potential damage to the photometric camera when idle, and reducing the impact of environmental factors on the photometric camera. Therefore, by adjusting the close engagement of the slider and the sliding gear, the photometric camera can be protected. At the same time, when the photometric camera needs to be used for detection, the protective baffle can be manually rotated in the opposite direction to rotate it away from the test base with the sliding gear as the center, exposing the photometric camera for normal detection.

[0017] 2. The present invention provides a plurality of guide frames on both sides of the interior of the photometer tester, and the guide frames are located on both sides of the interior of the lifting support. By passing the guide frames through both sides of the interior of the lifting support, the movement of the lifting support is limited, and the lifting support can only move vertically along the two sides of the outer wall of the guide frame during the movement, so that the lifting support and the shading baffles on both sides of the top of the lifting support can move steadily and smoothly along the outer wall of the guide frame toward the top of the device.

[0018] 3. In the photometric test preparation stage of the sample of the present invention, the operator needs to accurately move 1-2 μL of sample solution to the surface of the lower sample column. After the sample is placed, the upper base is carefully covered on the top of the lower base to ensure the stability of the sample and avoid external interference. At this time, the first motor located in the center of the photometer tester is activated, and its output end drives the power shaft and the power gears on both sides of the outer wall of the power shaft to rotate. The outer wall of one side of the power gear is meshed and rotatably connected with the outer wall of one end of the double-headed bevel gear, so that the rotation of the power shaft can be accurately transmitted to multiple double-headed bevel gears through gear meshing. These double-headed bevel gears are distributed on both sides of the power shaft. Through gear meshing transmission, the power shaft can simultaneously drive the lifting support The first drive gear and the second drive gear on both sides of the seat rotate toward the inner center of the photometer tester. With the synchronous rotation of the first drive gear and the second drive gear, the lifting support and the shading baffles on both sides of the top thereof move along the outer wall of the guide frame toward the top of the outer wall of the guide frame under the action of gear meshing, so that the shading baffle can perfectly block the ambient light on both sides of the photometric camera, thereby eliminating the interference of external light on the photometric measurement. Therefore, through the action of the first motor and the gear meshing, it is ensured that the photometric camera can effectively avoid the interference of external light on the test process during the measurement process, and at the same time effectively reduce the measurement error caused by ambient light, thereby ensuring that stable and reliable test results can be obtained under different lighting conditions.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] By opening a set of corresponding slide grooves 208 on one side of the lower base 2, and by penetrating one side of the outer wall of the adjusting slider 207 with one end of the inner side of the slide groove 208, the adjusting slider 207 is limited so that the adjusting slider 207 can only move horizontally along the slide groove 208 during the movement;

[0033] A sliding gear 209 is provided on one side of the lower base 2, and an outer wall of one end of the sliding gear 209 penetrates through one side of the lower base 2 and is fixed to an outer wall of one side of the protective baffle 206;

[0034] When the device is idle, the adjusting slider 207 can be pushed along the inner wall of the slide groove 208, and the adjusting slider 207 and the sliding gear 209 can rotate to drive the protective baffle 206 to rotate with the sliding gear 209 as the center, so that the protective baffle 206 fits with the outer wall of one side of the test base 204 and protects the photometric camera 205;

[0035] After 1-2 μL of sample solution is transferred to the surface of the lower sample column 202, the upper base 201 is covered on the top of the lower base 2, and the first motor 3 located in the center of the photometer tester 1 is activated, and the power shaft 304 and the power gears 305 on both sides of the outer wall thereof are driven to rotate through the output end thereof, because the outer wall of one side of the power gear 305 is meshed with the outer wall of one end of the double-headed cone gear 306 and is rotatably connected;

[0036] As the power shaft 304 rotates, the power shaft 304 drives the multiple double-headed bevel gears 306 located on both sides of the power shaft 304 to rotate on both sides of the power shaft 304 through gear meshing. By arranging multiple double-headed bevel gears 306 on both sides of the power shaft 304 through gear meshing transmission, the power shaft 304 can simultaneously drive the first driving gear 307 and the second driving gear 308 on both sides of the lifting support 303 to rotate toward the center of the photometer tester 1 at the same time;

[0037] In view of the fact that a plurality of guide frames 302 are arranged on both sides of the interior of the photometer tester 1, and the guide frames 302 are located on both sides of the interior of the lifting support 303, the movement of the lifting support 303 is limited by passing the guide frames 302 through both sides of the interior of the lifting support 303, and the lifting support 303 can only move vertically along both sides of the outer wall of the guide frames 302 during the movement;

[0038] As the first driving gear 307 and the second driving gear 308 on both sides of the photometer tester 1 rotate simultaneously, the lifting support 303 and the light shielding baffles 301 on both sides of the top thereof are driven to move simultaneously along the outer wall of the guide frame 302 toward the top of the outer wall of the guide frame 302 under the action of gear meshing, so that the light shielding baffles 301 perfectly shield the ambient light on both sides of the photometric camera 205;

[0039] Thus, through the action of the first motor 3 and the gear meshing, the photometric camera 205 can effectively avoid the interference of external light on the test process during the measurement process, and at the same time effectively reduce the measurement error caused by ambient light, ensuring that stable and reliable test results can be obtained under different lighting conditions.

A rack is provided on the outer wall of the bottom end of the adjusting slider 207, and the center of the bottom surface of the adjusting slider 207 is rotatably connected to the center of the top surface of the sliding gear 209 through the meshing of the rack.

[0041] By opening a set of corresponding slide grooves 208 on one side of the lower base 2, and by penetrating one side of the outer wall of the adjusting slider 207 with one end of the inner side of the slide groove 208, the adjusting slider 207 is limited so that the adjusting slider 207 can only move horizontally along the slide groove 208 during the movement;

[0042] A sliding gear 209 is provided on one side of the lower base 2, and an outer wall of one end of the sliding gear 209 penetrates through one side of the lower base 2 and is fixed to an outer wall of one side of the protective baffle 206;

[0043] When the device is idle, the adjusting slider 207 can be pushed along the inner wall of the slide groove 208, and the adjusting slider 207 and the sliding gear 209 can rotate to drive the protective baffle 206 to rotate with the sliding gear 209 as the center, so that the protective baffle 206 fits with the outer wall of one side of the test base 204 and protects the photometric camera 205;

[0044] By adjusting the tight engagement of the slider 207 and the sliding gear 209, the photometric camera 205 can be protected. At the same time, when the photometric camera 205 needs to be used for detection, the protective baffle 206 can be manually rotated in the opposite direction to rotate away from the test base 204 with the sliding gear 209 as the center, exposing the photometric camera 205 for normal detection work.

[0048] In view of the fact that a plurality of guide frames 302 are arranged on both sides of the interior of the photometer tester 1, and the guide frames 302 are located on both sides of the interior of the lifting support 303, the movement of the lifting support 303 is limited by passing the guide frames 302 through both sides of the interior of the lifting support 303, and the lifting support 303 can only move vertically along both sides of the outer wall of the guide frames 302 during the movement;

[0050] Thus, through the action of the first motor 3 and the gear meshing, the photometric camera 205 can effectively avoid the interference of external light on the test process during the measurement process, and at the same time effectively reduce the measurement error caused by ambient light, ensuring that stable and reliable test results can be obtained under different lighting conditions.

[0051] Working principle: A set of corresponding slide grooves 208 are provided on one side of the lower base 2, and one side of the outer wall of the adjusting slider 207 is penetrated with one end of the inner side of the slide groove 208 to limit the adjusting slider 207 so that the adjusting slider 207 can only move horizontally along the slide groove 208 during the movement;

[0052] A sliding gear 209 is provided on one side of the lower base 2, and an outer wall of one end of the sliding gear 209 penetrates through one side of the lower base 2 and is fixed to an outer wall of one side of the protective baffle 206;

By arranging multiple double-headed bevel gears 306 on both sides of the power shaft 304 through gear meshing transmission, the power shaft 304 can simultaneously drive the first driving gear 307 and the second driving gear 308 on both sides of the lifting support 303 to rotate toward the center of the photometer tester 1 at the same time;

[0056] In view of the fact that a plurality of guide frames 302 are arranged on both sides of the interior of the photometer tester 1, and the guide frames 302 are located on both sides of the interior of the lifting support 303, the movement of the lifting support 303 is limited by passing the guide frames 302 through both sides of the interior of the lifting support 303, and the lifting support 303 can only move vertically along both sides of the outer wall of the guide frames 302 during the movement;

[0057] As the first driving gear 307 and the second driving gear 308 on both sides of the photometer tester 1 rotate simultaneously, the lifting support 303 and the light shielding baffles 301 on both sides of the top thereof are driven to move simultaneously along the outer wall of the guide frame 302 toward the top of the outer wall of the guide frame 302 under the action of gear meshing, so that the light shielding baffles 301 perfectly shield the ambient light on both sides of the photometric camera 205;

[0058] Therefore, through the action of the first motor 3 and the gear meshing, it is ensured that the photometric camera 205 can effectively avoid the interference of external light on the test process during the measurement process.
