Technical Field

[0001] This utility model relates to the field of chemical analysis technology, specifically to a liquid chromatography analysis and detection device. Background Technology

[0002] Liquid chromatography is a high-efficiency analytical instrument that separates sample molecules based on the differences in their distribution between the stationary and mobile phases. It is widely used in pharmaceuticals, chemicals, food, and environmental fields.

[0003] A search revealed patent CN221847239U, which describes a liquid chromatograph comprising a housing with a placement plate fixedly connected to the top of the housing; an installation mechanism for quickly installing and fixing mobile phase solution bottles, the installation mechanism being disposed on the inner wall of the placement plate; by setting up the installation mechanism and placement components, several clamps can quickly fix and limit the mobile phase solution bottles, preventing them from shaking during installation and improving the limiting effect of the device; the clamps and a first spring telescopic rod can stably support the mobile phase solution bottles; the clamps and a guide block at the top can cooperate to quickly install the mobile phase solution bottles; the top of the guide block is arc-shaped to guide the mobile phase solution bottles, improving the installation speed of the device; and a protective plate on the inner wall of the clamps can protect the mobile phase solution bottles, enabling quick placement and installation of the mobile phase solution bottles and improving the installation speed of the mobile phase solution bottles.

[0004] In chromatographic analysis (such as HPLC and GC), directly observing the solvent level and promptly replenishing or replacing the solvent are crucial steps to ensure experimental continuity and data accuracy. To prevent photodegradation of solvents (such as acetonitrile), some solution bottles are made with dark-colored containers. However, these dark containers can easily obstruct the view of the solvent level, making it difficult for operators to accurately determine the level. Furthermore, due to the obstruction caused by the dark containers, operators may forget or miss observing and replenishing the solvent level, negatively impacting experimental continuity and data accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a liquid chromatography analysis and detection device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a liquid chromatography analysis and detection device, comprising a device body, a placement plate installed at the top of the device body, placement slots evenly distributed at the top of the placement plate, a solution bottle embedded in each placement slot, and a prompting component provided in each placement slot;

[0007] The prompting component includes a base plate disposed inside the placement slot, a spring disposed at the bottom end of the base plate, and first ear plates fixedly connected to both sides of the base plate, with a control switch disposed above one of the first ear plates.

[0008] As a further preferred embodiment of this technical solution, an adjusting plate is installed at the bottom end of the spring, and second ear plates are fixedly connected to both sides of the adjusting plate. A threaded rod and a limiting shaft are respectively embedded in the inner wall of the two second ear plates. The threaded rod and the limiting shaft are both installed inside the placement plate. The second ear plates are slidably connected to the limiting shaft, and the second ear plates are threadedly connected to the threaded rod. An adjusting block is fixedly installed at the top end of the threaded rod.

[0009] A hook is fixedly installed at the top of the limiting shaft.

[0010] As a further preferred embodiment of this technical solution, the two first ear plates are slidably mounted on the outer walls of the threaded rod and the limiting shaft, respectively.

[0011] As a further preferred embodiment of this technical solution, an indicator ring is provided above the placement groove, and a third ear plate is fixedly connected to both sides of the indicator ring. The two third ear plates are respectively installed on the outer wall of the threaded rod and the limiting shaft, and the third ear plates are threadedly connected to the threaded rod.

[0012] As a further preferred embodiment of this technical solution, the inner wall of the indicator ring is provided with a hollow portion, and the hollow portion is evenly distributed in a ring array.

[0015] This invention provides a liquid chromatography analysis and detection device, which has the following beneficial effects:

[0016] (1) By setting up a prompting component, this utility model allows the solution bottle to be placed on top of the base plate during operation. The weight of the solution bottle presses down on the base plate, causing the base plate to compress the spring and store elastic potential energy. When the solution inside the solution bottle decreases, the decrease in gravity causes the spring to gradually release elastic potential energy, driving the base plate to move upward. The movement of the base plate causes the first ear plate to move. When the solution inside the solution bottle decreases to a certain threshold, the first ear plate moves to the bottom of the control switch and contacts it, controlling the external buzzer to sound an alarm, prompting the staff to add or replace the solution. By prompting the staff in the above way, the problem of the dark solution bottle obscuring the liquid level and making it difficult to accurately judge the liquid level, and the forgetting or omission of observing and replenishing the liquid level, which would negatively affect the continuity of the experiment and the accuracy of the data, can be prevented. The solvent can be added in time to ensure the continuity of the experiment and the accuracy of the data.

[0017] (2) This utility model adjusts the extension and contraction of the spring inside the placement groove by adjusting the adjusting plate. When using different solutions or when it is necessary to adjust the remaining solution in the solution bottle to trigger the threshold, the adjusting block is rotated to drive the threaded rod to rotate. The rotation of the threaded rod drives the second ear plate to move. The movement of the second ear plate drives the adjusting plate to move inside the placement groove, changing the extension and contraction of the spring, thereby adjusting the trigger threshold and improving the adaptability and practicality of the device.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, a liquid chromatography analysis and detection device includes a device body 1, a placement plate 2 is installed on the top of the device body 1, and placement slots 3 are evenly opened on the top of the placement plate 2. A solution bottle 4 is embedded in the interior of each placement slot 3, and a prompting component is provided inside each placement slot 3.

[0025] The prompting component includes a base plate 5 set inside the placement slot 3, a spring 9 set at the bottom end of the base plate 5, and first ear plates 6 fixedly connected to both sides of the base plate 5, with a control switch 21 set above one of the first ear plates 6.

[0026] The existing patent CN221847239U discloses a liquid chromatograph, which discloses the main body 1 and the placement plate 2 of the device proposed in this application. The technical means will not be described in detail here.

[0027] The control switch 21 is connected to an external buzzer;

[0028] During operation, the solution bottle 4 is placed on top of the base plate 5. The weight of the solution bottle 4 presses down the base plate 5, causing the base plate 5 to compress the spring 9 and store elastic potential energy.

[0029] When the solution inside the solution bottle 4 decreases, the spring 9 gradually releases its elastic potential energy due to the decrease in gravity, causing the base plate 5 to move upward. The movement of the base plate 5 causes the first ear plate 6 to move. When the solution inside the solution bottle 4 decreases to a certain threshold, the first ear plate 6 moves to the bottom of the control switch 21 and contacts it, controlling the external buzzer to sound an alarm, prompting the staff to add or replace the solution.

[0030] The above method serves as a reminder to staff to prevent problems such as the dark-colored solution bottle 4 obstructing the view of the liquid level, making it difficult to accurately judge the solvent level, and causing the forgetting or omission of observing and replenishing the solvent level, which could negatively impact the continuity of the experiment and the accuracy of the data. Solvent can be added in a timely manner to ensure the continuity of the experiment and the accuracy of the data.

[0031] like Figures 1 to 3 As shown, an adjusting plate 10 is installed at the bottom of the spring 9. A second ear plate 11 is fixedly connected to both sides of the adjusting plate 10. A threaded rod 7 and a limiting shaft 8 are respectively embedded in the inner wall of the two second ear plates 11. The threaded rod 7 and the limiting shaft 8 are both installed inside the placement plate 2. The second ear plate 11 is slidably connected to the limiting shaft 8. The second ear plate 11 is threadedly connected to the threaded rod 7. An adjusting block 12 is fixedly installed at the top of the threaded rod 7.

[0032] When using different solutions or when the threshold for triggering the prompt needs to be adjusted by adjusting the remaining solution in solution bottle 4, the threaded rod 7 is rotated by rotating the adjusting block 12. The rotation of the threaded rod 7 causes the second ear plate 11 to move. The movement of the second ear plate 11 causes the adjusting plate 10 to move in the placement groove 3, changing the extension and contraction of the spring 9, thereby adjusting the trigger threshold and improving the adaptability and practicality of the device.

[0033] The top of the limiting shaft 8 is fixedly equipped with a hook 13, which can be used to temporarily suspend infusion lines, gas lines, etc.

[0034] like Figures 1 to 3 As shown, the two first ear plates 6 are slidably mounted on the outer walls of the threaded rod 7 and the limiting shaft 8, respectively.

[0035] like Figures 1 to 3 As shown, an indicator ring 14 is provided above the placement groove 3. A third ear plate 15 is fixedly connected to both sides of the indicator ring 14. The two third ear plates 15 are respectively installed on the outer wall of the threaded rod 7 and the limiting shaft 8. The third ear plates 15 are threadedly connected to the threaded rod 7.

[0036] The indicator ring 14 is located on the outside of the solution bottle 4, which makes it convenient for staff to observe the solution level that triggers the prompt.

[0037] Furthermore, when the threaded rod 7 rotates, it drives the third ear plate 15 to move, thereby causing the indicator ring 14 to move synchronously with the adjusting plate 10 for adjustment.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, the inner wall of the indicator ring 14 has a hollowed-out portion 18, which is evenly distributed in a ring array.

[0039] like Figures 1 to 4 As shown, an installation ring 16 is provided at the top of the indicator ring 14, and an absorbent cotton 17 is installed inside the installation ring 16. The absorbent cotton 17 is located on the outer wall of the solution bottle 4.

[0040] The absorbent cotton 17 is located on the outer wall of the solution bottle 4. When adding solution to the solution bottle 4 or taking out items from the solution bottle 4, any solution that is accidentally spilled can be absorbed by the absorbent cotton 17, preventing the solution from spilling on the surface of the device and improving the cleanliness of the device.

[0041] like Figure 4 As shown, the bottom end of the mounting ring 16 is uniformly equipped with connecting shafts 19 in a ring array. The connecting shafts 19 are embedded in the inner wall of the connecting hole 20, which is opened on the inner wall of the indicator ring 14.

[0042] The mounting ring 16 is installed onto the top of the indicator ring 14 by inserting the connecting shaft 19 into the inner wall of the connecting hole 20, thus connecting them;

[0043] When it is necessary to replace the absorbent cotton 17, the connecting shaft 19 can be slid out from the inner wall of the connecting hole 20 by moving the mounting ring 16 upwards, which is convenient for maintenance and replacement.

[0044] This utility model provides a liquid chromatography analysis and detection device, the specific working principle of which is as follows:

[0045] Before starting work, first place the solution bottle 4 in the placement slot 3, and then adjust the threshold of the remaining solution in the solution bottle 4 to trigger the prompt according to different solutions. By rotating the adjusting block 12, the threaded rod 7 is rotated. The rotation of the threaded rod 7 causes the second ear plate 11 to move. The movement of the second ear plate 11 causes the adjusting plate 10 to move in the placement slot 3, changing the extension and contraction of the spring 9, thereby adjusting the trigger threshold.

[0046] When the threaded rod 7 rotates, it simultaneously drives the third ear plate 15 to move. The movement of the third ear plate 15 drives the indicator ring 14 to move synchronously with the adjusting plate 10, so that the indicator ring 14 is located at the solution level that triggers the prompt inside the solution bottle 4.

[0047] The indicator ring 14 is located on the outside of the solution bottle 4, which makes it convenient for staff to observe the solution level that triggers the prompt.

[0048] During operation, when the solution inside solution bottle 4 decreases, the decrease in gravity causes spring 9 to gradually release its elastic potential energy, which in turn causes base plate 5 to move upward. The movement of base plate 5 causes the first ear plate 6 to move. When the solution inside solution bottle 4 decreases to a certain threshold, the first ear plate 6 moves to the bottom of control switch 21 and contacts it, controlling the external buzzer to sound an alarm, prompting staff to add or replace the solution.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
