Description

Technical Field

[0001] This application relates to the technical field of photometers, and particularly to a quantitative sampling device for protein labeling. Background Art

[0002] The quantitative sampling device for protein labeling is an ultra-micro spectrophotometer. The ultra-micro spectrophotometer is based on the principle of spectrophotometry and determines the concentration of a substance by measuring the absorption or transmission of light of a specific wavelength by the substance in a solution. It mainly includes a light source, a sample chamber, a detector, and a signal processing system. The light emitted by the light source is split into light beams of different wavelengths by a spectroscopic device, and the wavelength corresponding to the absorption peak of the substance to be measured is selected. The solution in the sample chamber is placed in the optical path, and when the light beam passes through the solution, it is absorbed or transmitted by the substance in the solution. The detector converts the light signal into an electrical signal, and then the electrical signal is transmitted to the signal processing system for processing and analysis to obtain the concentration of the substance.

[0003] The application scenario of the ultra-micro spectrophotometer is usually in a relatively clean environment such as a hospital laboratory or a factory inspection room. However, during sampling detection, the earlier the sample is detected, the more accurate the detected data will be. Therefore, in the prior art, an ultra-micro spectrophotometer with a smaller system is set up to facilitate the staff to carry it to the site for detection, thereby improving the accuracy of the detected data.

[0004] However, due to the influence of machines, the environment at the factory manufacturing site is not very clean, which results in a decrease in the accuracy rate of the detected data of the ultra-micro spectrophotometer. Therefore, a quantitative sampling device for protein labeling is needed. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, the purpose of this application is to provide a quantitative sampling device for protein labeling, which is used to solve the technical problem that the environment at the manufacturing site in the prior art is not very clean, resulting in a decrease in the accuracy rate of the detected data of the ultra-micro spectrophotometer.

[0006] The above object of this application is achieved through the following technical solutions: A quantitative sampling device for protein labeling includes a box body and a photometer placed in the box body. The box body has an opening facing upwards, and through slots are opened on the opposite side walls of the box body that penetrate the box body. A box cover is provided on one side of the box body and is inserted into the box body through the through slots. Two through openings that penetrate the box cover are opened on the upper surface of the box cover, and a plurality of triangular rubbers are fixedly provided on the inner wall of the through openings. The triangular rubbers are evenly distributed annularly on the inner wall of the through openings and cover the through openings.

[0007] By adopting the above technical solution, the inside of the box is first disinfected in advance. Then, when it is necessary to take the photometer to the site for detection, the photometer is placed inside the box. Then, the box cover is pushed to block the opening of the box. Then, the box is moved to the site. After the substance to be detected is extracted at the site, through the through-hole on the box cover, first push the triangular rubber so that the triangular rubber sinks into the box. The sunken triangular rubber no longer completely blocks the through-hole. Then, the staff sends the substance to be detected into the box and places the substance to be detected on the photometer for detection. At this time, the triangular rubber squeezes the periphery of the staff's arm extending into the box to prevent dust from entering and affecting the detection result. In this way, the technical problem that the environment at the manufacturing site in the prior art is not very clean, resulting in a decrease in the data accuracy rate of the ultra-micro spectrophotometer, is solved, and the data accuracy rate of on-site detection of the photometer is improved.

[0008] Furthermore, the box cover is made of transparent plastic.

[0009] By adopting the above technical solution, the box cover made of transparent plastic facilitates the staff to observe the condition of the photometer inside the box and is convenient for operation.

[0010] Furthermore, a protective structure for preventing dust accumulation on the triangular rubber is provided on the upper surface of the box cover.

[0011] By adopting the above technical solution, although the setting of the triangular rubber can prevent dust or foreign objects from entering the box during on-site detection by the staff, if dust accumulates on the surface of the triangular rubber, the staff will bring the dust into the box when pushing the triangular rubber, resulting in a decrease in the data accuracy rate of the detection. The setting of the protective structure solves this technical problem. When the photometer is not in use, the upper surface of the triangular rubber is blocked by the protective device to prevent dust accumulation. In this way, when used next time, there will be no dust left on the surface of the triangular rubber, and it will not affect the data accuracy rate of the photometer detection.

[0012] Furthermore, the protective structure includes fixing strips fixedly arranged on both sides of the box cover and a protective plate arranged between the two fixing strips. Insertion openings are formed on the opposite surfaces of the two fixing strips, and both sides of the protective plate are inserted into the two fixing strips through the insertion openings.

[0013] By adopting the above technical solution, sliding the protective plate to block the triangular rubber can prevent dust from accumulating on the surface of the triangular rubber.

[0014] Furthermore, attracting magnets are fixedly arranged on the bottom surface of the box.

[0015] By adopting the above technical solution, although the setting of the box can provide a clean environment for the photometer to perform detection, there are usually multiple machines working at the manufacturing site, which makes the box susceptible to the vibration generated by multiple machines working, causing the photometer located in the box to be affected by the vibration, thereby reducing the accuracy of the detection data. The setting of the attraction magnet solves this technical problem. The box is placed on a metal that can be adsorbed by a magnet, so that the attraction magnet adsorbs the metal. In this way, the box will not be affected by the vibration, thereby improving the stability of the photometer detection.

[0016] Furthermore, the inner bottom surface of the box body is provided with a fixing structure for fixing the photometer.

[0017] By adopting the above technical solution, although the setting of the attraction magnet fixes the box so that the box does not vibrate, thereby improving the detection stability of the photometer, the transmission of the vibration frequency through the box will still slightly affect the photometer in the box, causing the photometer to shake slightly, resulting in erroneous detection data. The setting of the fixed structure solves this technical problem. The photometer is fixed in the box through the fixed structure. After being restricted by the fixed structure, the photometer will not shake, thereby further improving the detection stability of the photometer.

[0018] Furthermore, the fixing structure includes a connecting plate fixedly connected to the bottom surface of the box body and a fixing column fixedly connected to the bottom surface of the photometer. The connecting plate is provided with a fixing hole adapted to the fixing column. An end of the fixing column away from the photometer is fixedly connected to an adsorption magnet, and the adsorption magnet has an attraction surface facing the attraction magnet.

[0019] By adopting the above technical solution, when placing the photometer in the box, first align the fixing column with the fixing hole, and then put the photometer in. At this time, the adsorption magnet adsorbs the magnet through the box, and the photometer is fixed due to the limitation of the fixing hole, so that the photometer can be restricted and will not shake.

[0020] Furthermore, a wiring hole is provided on one side of the box body, and a filling rubber is provided inside the wiring hole.

[0021] By adopting the above technical solution, the wires of the photometer go out from the wiring hole, and the filling rubber squeezes the wires of the photometer to prevent dust from entering the box through the gap between the wires of the photometer and the inner wall of the wiring hole.

[0022] In summary, the present application includes at least one of the following beneficial technical effects.

[0023] Through the arrangement of the box body, the box cover and the triangular rubber, it is achieved that the box body is first disinfected in advance, and then when the photometer needs to be brought to the site for detection, the photometer is placed in the box body, and then the box cover is pushed to block the box body opening, and then the box body is moved to the present, and after the substance to be detected is extracted on site, the triangular rubber is first pushed in the box body through the opening on the box cover to make the triangular rubber concave into the box body, and the concave triangular rubber no longer completely blocks the opening, and then the staff sends the substance to be detected into the box body and places the substance to be detected on the photometer for detection. At this time, the triangular rubber squeezes the periphery of the staff's arm inserted into the box body to prevent dust from entering and affecting the detection results, thereby improving the data accuracy of the on-site detection of the photometer.

[0024] By setting up the protective structure, when the photometer is not in use, the protective plate can be slid to block the triangular rubber to prevent dust from accumulating on the surface of the triangular rubber. In this way, when it is used next time, there will be no dust on the surface of the triangular rubber, and the accuracy of the photometer detection data will not be affected.

[0025] By setting the fixing structure and the attraction magnet, it is possible to place the box on a metal that can be adsorbed by the magnet, so that the attraction magnet adsorbs the metal, so that the box will not be affected by vibration, thereby improving the stability of the photometer detection. When the photometer is placed in the box, first align the fixing column with the fixing hole, and then put the photometer in. At this time, the adsorption magnet adsorbs the attraction magnet across the box, and the photometer is fixed due to the limitation of the fixing hole. In this way, the photometer can be restricted from shaking, thereby further improving the stability of the photometer detection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] Example, referring to Figure 1 , a quantitative sampling device for protein labeling, including a box body 1 and a photometer 2 placed in the box body 1. The box body 1 has an upward opening, and through slots 10 penetrating the box body 1 are provided on opposite side walls. A box cover 3 inserted into the box body 1 through the through slots 10 is provided on one side of the box body 1. Two through openings 30 penetrating the box cover 3 are provided on the upper surface of the box cover 3. A plurality of triangular rubbers 31 are fixedly provided on the inner wall of the through openings 30. The triangular rubbers 31 are evenly distributed in a ring on the inner wall of the through openings 30 and cover the through openings 30. First, disinfect the inside of the box body 1 in advance. Then, when the photometer 2 needs to be taken to the site for detection, place the photometer 2 in the box body 1, then push the box cover 3 to block the opening of the box body 1, and then move the box body 1 to the site. After extracting the substance to be detected at the site, through the through openings 30 on the box cover 3, first push the triangular rubbers 31 to make the triangular rubbers 31 sink into the box body 1. The sunken triangular rubbers 31 no longer completely block the through openings 30. Then, the staff sends the substance to be detected into the box body 1 and places the substance to be detected on the photometer 2 for detection. At this time, the triangular rubbers 31 squeeze the periphery of the staff's arm extending into the box body 1 to prevent dust from entering and affecting the detection result. In this way, the technical problem that the environmental cleanliness of the manufacturing site in the prior art is not very high, resulting in a decrease in the data accuracy rate of the ultra-micro spectrophotometer 2, is solved, and the data accuracy rate of the on-site detection of the photometer 2 is improved. Moreover, the box cover 3 is made of transparent plastic, and the box cover 3 made of transparent plastic is convenient for the staff to observe the condition of the photometer 2 in the box body 1 and is convenient for operation.

[0033] Although the setting of the triangular rubbers 31 can prevent dust or foreign objects from entering the box body 1 when the staff conducts on-site detection, if dust accumulates on the surface of the triangular rubbers 31, the staff will bring the dust into the box body 1 when pushing the triangular rubbers 31, resulting in a decrease in the data accuracy rate of the detection. To solve this technical problem, referring to Figure 2 , in this embodiment, a protection structure 4 for preventing dust accumulation on the triangular rubbers 31 is provided on the upper surface of the box cover 3. The protection structure 4 includes fixing strips 40 fixedly provided on both sides of the box cover 3 and a protection plate 41 provided between the two fixing strips 40. Insertion openings 42 are provided on the opposite sides of the two fixing strips 40 facing each other. Both sides of the protection plate 41 are inserted into the two fixing strips 40 through the insertion openings 42. When the photometer 2 is not in use, slide the protection plate 41 to block the triangular rubbers 31, which can prevent dust from accumulating on the surface of the triangular rubbers 31. In this way, when used next time, there will be no dust left on the surface of the triangular rubbers 31, and it will not affect the data accuracy rate of the photometer 2 detection.

[0034] Although the setting of the box 1 can provide a clean environment for the photometer 2 to perform detection, there are usually multiple machines working at the manufacturing site, which makes the box 1 susceptible to the vibrations generated by the multiple machines working, causing the photometer 2 located in the box 1 to be affected by the vibrations, thereby reducing the accuracy of the detection data. In order to solve this technical problem, in this embodiment, an attraction magnet 11 is fixedly provided on the bottom surface of the box 1, and the box 1 is placed on a metal that can be adsorbed by the magnet, so that the attraction magnet 11 adsorbs the metal. In this way, the box 1 will not be affected by the vibration, thereby improving the detection stability of the photometer 2. A wiring hole 12 is provided on one side of the box 1, and a filling rubber 13 is provided inside the wiring hole 12. The wires of the photometer 2 go out of the wiring hole 12, and the filling rubber 13 squeezes the wires of the photometer 2 to prevent dust from entering the box 1 from the gap between the wires of the photometer 2 and the inner wall of the wiring hole 12.

[0035] Although the magnet 11 fixes the box 1 so that the box 1 does not vibrate, thereby improving the stability of the detection of the photometer 2, the vibration frequency transmitted through the box 1 will still slightly affect the photometer 2 in the box 1, causing the photometer 2 to shake slightly, resulting in errors in the detection data. Figure 3 , Figure 4 In order to solve this technical problem, in this embodiment, a fixing structure 5 for fixing the photometer 2 is provided on the bottom surface of the box body 1. The fixing structure 5 includes a connecting plate 50 fixedly connected to the bottom surface of the box body 1 and a fixing column 51 fixedly connected to the bottom surface of the photometer 2. The connecting plate 50 is provided with a fixing hole 52 adapted to the fixing column 51. An adsorption magnet 53 is fixedly connected to one end of the fixing column 51 away from the photometer 2. The adsorption magnet 53 has an attractive surface facing the attractive magnet 11. When the photometer 2 is placed in the box body 1, the fixing column 51 is first aligned with the fixing hole 52, and then the photometer 2 is put in. At this time, the adsorption magnet 53 adsorbs the attractive magnet 11 across the box body 1. Because of the restriction of the fixing hole 52, the photometer 2 is fixed, so that the photometer 2 can be restricted from shaking, which further improves the detection stability of the photometer 2.

[0036] Specific implementation process: first, align the fixing column 51 at the bottom of the photometer 2 with the fixing hole 52 and put it into the box 1, then slide the box cover 3 to cover the opening of the box 1, and then transport the box 1 to the manufacturing site, and place the box 1 on a metal plate that can be adsorbed by a magnet at the manufacturing site, then pull open the protective plate 41, then extract the substance to be detected, push open the triangular rubber 31, put your hand into the box 1, and operate the photometer 2 for detection.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
