Description

Technical Field

[0001] This utility model relates to the field of fluorescent reagent storage technology, specifically a fluorescent reagent storage box with light-shielding function. Background Technology

[0002] Fluorescent reagents are widely used in biological detection, medical diagnosis, and scientific research experiments. Their core components (such as fluorescently labeled probes and enzymes) are extremely sensitive to light and temperature. Light exposure can trigger photochemical reactions, leading to attenuation of fluorescence signals or reagent decomposition; temperature fluctuations may destroy enzyme activity or cause molecular denaturation. For example, luciferase reagents are prone to inactivation under repeated freeze-thaw cycles or high-temperature environments, affecting the accuracy of detection results.

[0003] Most traditional reagent kits are made of transparent or semi-transparent materials, which cannot effectively block ultraviolet and visible light, leading to a decline in the performance of fluorescent reagents after long-term exposure. At the same time, when storing at low temperatures, the entire kit is usually placed in the refrigerator. When taking it out, the lid needs to be opened to let all the reagents inside leak out before they can be used, which will cause large temperature fluctuations and affect the activity of unused reagents. To address these issues, we propose a fluorescent reagent storage box with light-shielding function. Utility Model Content

[0004] The purpose of this invention is to provide a fluorescent reagent storage box with light-shielding function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fluorescent reagent storage box with light-shielding function, comprising a cylindrical box body, a switching shaft coaxially rotatably sleeved inside the cylindrical box body, a ratchet assembly fixedly connected to the top of the switching shaft, the ratchet assembly being movably disposed inside a protective cover, the protective cover being fixedly connected to the top outer wall of the cylindrical box body and the switching shaft being rotatably sleeved inside the protective cover, and a switching knob coaxially fixedly connected to the top of the switching shaft;

[0006] Multiple partitions are fixedly connected to the outer wall of the switching shaft. The multiple partitions are slidably disposed in the cylindrical box. A fan-shaped support plate is fixedly connected to the bottom of each of two adjacent partitions. A positioning groove is recessed in the top surface of the fan-shaped support plate. A circular opening is coaxially opened at the bottom of the positioning groove. A rectangular opening is opened on the side of the circular opening away from the switching shaft. An insertion port is opened on one side of the top of the cylindrical box. A sliding opening is opened on the side of the insertion port away from the switching shaft. A picking rod is slidably sleeved in the sliding opening. A lifting plate is fixedly connected to one side of the bottom end of the picking rod. The lifting plate is movably disposed at the bottom of the fan-shaped support plate.

[0007] Preferably, the inlet is fitted with a sealing cap via an interference fit.

[0008] Preferably, the partitions are evenly distributed around the circumference, and a fan-shaped cavity is formed between two adjacent partitions.

[0009] Preferably, the top of the protective cover has an arc-shaped opening.

[0010] Preferably, the ratchet assembly includes a ratchet, a pawl, a spring, a lever, and a cylindrical pin. The ratchet is fixedly sleeved on the top of the switching shaft. The ratchet is engaged with one end of the pawl, and the other end of the pawl is rotatably connected to the cylindrical pin. One end of the cylindrical pin is fixedly connected to the top outer wall of the cylindrical box. The outer wall of the pawl away from the ratchet is fixedly connected to one end of the spring. The other end of the spring is fixedly connected to the inner wall of the protective cover. The end of the pawl away from the cylindrical box is fixedly connected to one end of the lever, and the other side of the lever slides out of the arc-shaped opening.

[0011] Preferably, the picking rod has an L-shaped structure, and the diameter of the insertion port is larger than the inner diameter of the positioning groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Place the fluorescent reagent bottles to be stored into the cylindrical box through the insertion port, and seal the insertion port with the sealing cap. The cylindrical box is made of light-shielding material, which can effectively block ultraviolet and visible light and prevent the performance of fluorescent reagents from deteriorating due to light exposure.

[0014] 2. When a fluorescent reagent bottle needs to be taken, rotate the switching knob to drive the switching shaft to rotate. The switching shaft drives the sector support plate to rotate through the partition, so that the corresponding sector support plate moves to below the placement port. At this time, pull the picking rod upward. The picking rod drives the lifting plate to move upward. The lifting plate passes through the rectangular opening and extends out from the circular opening, lifting the fluorescent reagent bottle in the positioning groove, making it easy for the user to take it out from the placement port. At the same time, during the taking process, the other fluorescent reagent bottles are still in an independent sealed state, which effectively reduces the influence of the external temperature on the unused reagents and avoids the overall temperature fluctuation caused by frequent opening of the box lid.

[0015] 3. When the ratchet assembly switches the rotating shaft, the one-way meshing characteristic of the ratchet and pawl ensures that the sector support plate will not rotate in the opposite direction after positioning, thus improving the stability of the reagent bottle positioning. When it is necessary to switch the sector cavity in the opposite direction, simply move the lever on the top of the protective cover to disengage the pawl from the ratchet, and the rotating shaft can be rotated in the opposite direction. The operation is convenient and flexible.

[0016] 4. Multiple circumferentially distributed partitions divide the internal space of the cylindrical box into independent sector-shaped cavities. Each sector-shaped cavity can store different types of fluorescent reagents separately. At the same time, the positioning grooves on the sector-shaped support plates can effectively fix the reagent bottles and prevent them from shaking or tipping over during storage.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a fluorescent reagent storage box with light-shielding function, including a cylindrical box body 1. The cylindrical box body 1 is made of light-shielding material (such as ABS plastic material) and the inner wall is fixedly connected with heat insulation material. A switching shaft 13 is coaxially rotatably sleeved inside the cylindrical box body 1. A ratchet assembly 4 is fixedly connected to the top of the switching shaft 13. The ratchet assembly 4 is movably disposed inside the protective cover 3. The protective cover 3 is fixedly connected to the top outer wall of the cylindrical box body 1 and the switching shaft 13 is rotatably sleeved inside the protective cover 3. A switching knob 2 is coaxially fixedly connected to the top of the switching shaft 13.

[0026] Multiple partitions 7 are fixedly connected to the outer wall of the switching shaft 13. The multiple partitions 7 are slidably disposed in the cylindrical box 1. A fan-shaped support plate 8 is fixedly connected to the bottom between two adjacent partitions 7. A positioning groove 9 is recessed in the top surface of the fan-shaped support plate 8. A circular opening 10 is coaxially opened at the bottom of the positioning groove 9. A rectangular opening 11 is opened on the side of the circular opening 10 away from the switching shaft 13. An inlet 101 is opened on the top side of the cylindrical box 1. A sliding opening 102 is opened on the side of the inlet 101 away from the switching shaft 13. A picking rod 6 is slidably sleeved in the sliding opening 102. A lifting plate 12 is fixedly connected to the bottom side of the picking rod 6. The lifting plate 12 is movably disposed at the bottom of the fan-shaped support plate 8. That is, an annular space is formed between the fan-shaped support plate 8 and the bottom wall of the cylindrical box 1. When the fan-shaped support plate 8 rotates in a circle, the lifting plate 12 is prevented from obstructing the fan-shaped support plate 8.

[0027] Example 2

[0028] Reference Figure 1-5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, a sealing cap 5 is interference-connected inside the inlet 101. The sealing cap 5 seals the inlet 101, thereby sealing the cylindrical box 1.

[0029] Specifically, the partitions 7 are evenly distributed around the circumference, and a fan-shaped cavity is formed between two adjacent partitions 7.

[0030] Specifically, the top of the protective cover 3 has an arc-shaped opening 31, centered on the cylindrical pin 45. This allows the user to manually operate the lever 44 to disengage the pawl 42 from the ratchet 41, enabling the switching shaft 13 to rotate in the opposite direction and meet the switching requirements of different sector cavities. The spring 43 in the ratchet assembly 4 always applies an elastic force to the pawl 42 towards the ratchet 41, ensuring stable engagement between the pawl 42 and the ratchet 41 under non-human-operated conditions, preventing accidental rotation of the switching shaft 13 due to external vibrations or other factors.

[0031] Specifically, the ratchet assembly 4 includes a ratchet 41, a pawl 42, a spring 43, a lever 44, and a cylindrical pin 45. The ratchet 41 is fixedly sleeved on the top of the switching shaft 13. The ratchet 41 is engaged with one end of the pawl 42. The other end of the pawl 42 is rotatably connected to the cylindrical pin 45. One end of the cylindrical pin 45 is fixedly connected to the top outer wall of the cylindrical box 1. The outer wall of the end of the pawl 42 away from the ratchet 41 is fixedly connected to one end of the spring 43. The other end of the spring 43 is fixedly connected to the inner wall of the protective cover 3. The end face of the pawl 42 away from the cylindrical box 1 is fixedly connected to one side of the lever 44. The other side of the lever 44 slides out of the arc-shaped opening 31.

[0032] The top surface of the fan-shaped support plate 8 is flush with the top of the partition plate 7. The top of the partition plate 7 slides in contact with the inner wall of the top of the cylindrical box 1, so that the adjacent partition plates 7 and the fan-shaped support plate 8 together form an independent fan-shaped space. With the light-shielding material of the cylindrical box 1 (such as ABS plastic), it can effectively block external light from entering the interior of each fan-shaped space, providing a light-proof storage environment for fluorescent reagents.

[0033] Specifically, the lifting rod 6 has an L-shaped structure, and a round handle for easy gripping is fixedly connected to the top of the lifting rod 6. The lifting rod 6 and the sliding opening 102 are fitted with a clearance, and a sealing ring is fixedly connected to the inner wall of the top of the cylindrical box 1 to further ensure the sealing of the clearance fit. This ensures that the lifting rod 6 can slide smoothly, and also reduces the amount of outside air or light entering the cylindrical box 1 through the sliding opening 102 by increasing the contact area between the lifting rod 6 and the sliding opening 102, further improving the sealing of the cylindrical box 1. The aperture of the opening 101 is larger than the inner diameter of the positioning groove 9. When the fluorescent reagent bottle is placed in the positioning groove 9, the bottom of the reagent bottle is embedded in the positioning groove 9. The circular opening 10 and the rectangular opening 11 provide room for the lifting plate 12 to rise, ensuring that the lifting plate 12 can smoothly push the reagent bottle out of the positioning groove 9. The bottom of the cylindrical box 1 is fixedly connected with an anti-slip rubber pad, which can increase the friction between the storage box and the table when it is placed, prevent the cylindrical box 1 from sliding and shifting during use, and improve the safety of use.

[0034] The working principle and process are as follows: Fluorescent reagent bottles to be stored are placed into the cylindrical box 1 through the placement port 101. One fluorescent reagent bottle is placed between each of two adjacent partitions 7. The bottom of the fluorescent reagent bottle is embedded in the positioning groove 9. By manually rotating the switching knob 2, the fixed switching shaft 13 is rotated. The switching shaft 13 then rotates the fixed partitions 7, thus switching the fan-shaped space formed between the partitions 7, facilitating the placement of fluorescent reagent bottles into each space. After placement, the placement port 101 is sealed with the sealing cap 5. When retrieving the reagent, the sealing cap 5 is opened, exposing the placement port 101. The lifting rod 6 is manually operated, causing the fixed lifting plate 12 to rise. The lifting plate 12 passes through the circular opening 10 and the rectangular opening 11 and extends upwards, accommodating the fluorescent reagent bottles in the positioning groove 9. The bottom of the reagent bottle is raised so that the top of the reagent bottle is exposed from the inlet 101, making it easy for the user to directly grasp the reagent bottle. When switching reagent bottles in different sector spaces between the partitions 7, the switching knob 2 is manually turned, which drives the switching shaft 13 and ratchet 41 to rotate synchronously. At this time, the teeth of the ratchet 41 squeeze the pawl 42, causing it to rotate around the cylindrical pin 45 and compress the spring 43. When it rotates to the next tooth position, the spring 43 resets and pushes the pawl 42 to re-engage with the ratchet 41, achieving one-way positioning. If counterclockwise switching is required, the lever 44 is manually moved to slide within the arc-shaped opening 31, causing the pawl 42 to overcome the elastic force of the spring 43 and disengage from the ratchet 41. Then the switching knob 2 can be turned in the opposite direction to the target position. After releasing the lever 44, the pawl 42 re-engages with the ratchet 41 under the action of the spring 43, completing the positioning.

[0035] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial improvements made to this utility model using this concept should be considered as infringing on the protection scope of this utility model.
