Abstract
Description
Technical Field
[0001] This utility model relates to the field of moisture-proof and oxidation-proof technology, and in particular to a moisture-proof and oxidation-proof reagent bottle. Background Technology
[0002] Reagent bottles are containers used to hold various chemical reagents, biological reagents, and pharmaceutical reagents. They are widely used in chemical experiments, pharmaceutical research and development, biological detection, and industrial production. In the fields of chemistry, medicine, and biology, the storage quality of reagents directly affects experimental results, product performance, and even safety of use.
[0003] Reagent bottles typically achieve a seal through a simple gasket connected to the cap via a threaded connection. However, this type of sealing structure has significant shortcomings. After prolonged use, the gasket is prone to aging and deformation due to compression, resulting in decreased elasticity and reduced fit with the bottle body and cap, creating tiny gaps that cannot effectively prevent the intrusion of external moisture and oxygen. Furthermore, the sealing structure lacks an active adjustment mechanism. Once the gasket becomes loose or does not fit tightly, it cannot be repaired externally; the gasket or the reagent bottle must be replaced. This not only increases usage costs but may also expose the reagent to air during replacement, leading to moisture absorption or oxidation and deterioration. To address this issue, we propose a moisture-proof and oxidation-proof reagent bottle. Utility Model Content
[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a moisture-proof and oxidation-proof reagent bottle, which provides a dry and oxygen-isolated storage environment for reagents, effectively preventing reagents from deteriorating due to moisture or oxidation, significantly extending the shelf life and effectiveness of reagents, and further reinforcing the threaded connection between the bottle cap and the bottle body to prevent the bottle cap from loosening due to vibration or collision during transportation or use, thus helping to maintain the sealing effect from the perspective of structural stability.
[0005] This utility model also provides a moisture-proof and oxidation-proof reagent bottle, including a bottle body, a bottle cap threadedly connected to the top of the bottle body, an expansion tube fixedly installed below the bottle cap, a first bolt inside the expansion tube, a rubber ring fixedly installed outside the expansion tube, a fixing ring above the rubber ring, and two second bolts inside the bottle cap.
[0006] According to the present invention, a moisture-proof and oxidation-proof reagent bottle is provided with an external thread on the outside of the first bolt and an internal bolt on the inside of the expansion tube, wherein the first bolt is threadedly connected to the expansion tube.
[0007] According to the present invention, in a moisture-proof and oxidation-proof reagent bottle, the lower end of the second bolt is in close contact with the upper surface of the fixing ring, one end of the expansion tube extends into the interior of the bottle body, and the outer surface of the rubber ring is in close contact with the inner wall of the bottle body.
[0008] According to the present invention, a moisture-proof and oxidation-proof reagent bottle is provided on the outside of the bottle body. A first buckle is fixedly installed above the first buckle. The second buckle is located on the outside of the bottle cap. The first buckle includes a first arc-shaped clamping plate, a second arc-shaped clamping plate, a first fixing plate, a second fixing plate, a movable rod, and a first nut. The second arc-shaped clamping plate is hinged to one end of the first arc-shaped clamping plate. The first fixing plate is fixedly installed to one end of the first arc-shaped clamping plate. The movable rod is hinged inside the first fixing plate. The second fixing plate is fixedly installed to one side of the second arc-shaped clamping plate. The first nut is provided on the outside of the movable rod. The second buckle includes a third arc-shaped clamping plate, a fourth arc-shaped clamping plate, a first support plate, a second support plate, a third bolt, and a second nut. One end of the third arc-shaped clamping plate is hinged to the fourth arc-shaped clamping plate, and the other end of the third arc-shaped clamping plate is fixedly installed with the first support plate.

[0010] Beneficial effects:
[0011] 1. The moisture-proof and oxidation-proof reagent bottle of this technical solution has an external rubber ring that can make close contact with the inner wall of the bottle, forming a highly efficient sealing barrier. By tightening the first bolt, the state of the expansion tube can be further adjusted to enhance the fit between the rubber ring and the inner wall of the bottle. At the same time, by using the second bolt to press down on the fixing ring, continuous pressure can be applied to the rubber ring to prevent it from loosening due to long-term use. The dual adjustment greatly improves the sealing reliability at the bottle mouth, effectively preventing external moisture and oxygen from entering the bottle, providing a dry and oxygen-isolated storage environment for the reagent, effectively preventing the reagent from deteriorating due to moisture or oxidation, and significantly extending the shelf life of the reagent.
[0012] 2. The first and second arc-shaped clamps of the first buckle fit tightly against the outside of the bottle body, and the third and fourth arc-shaped clamps of the second buckle firmly fix the bottle cap. The two are connected to form an integral structure, which can further strengthen the connection between the bottle cap and the bottle body by thread, and prevent the bottle cap from loosening due to vibration or collision during transportation or use. This helps to maintain the sealing effect from the perspective of structural stability. Attached Figure Description

A bottle cap 2 is threadedly connected to the top of the bottle body 1, achieving a sealing and leak-proof effect. An expansion tube 3 is fixedly installed below the bottle cap 2, which changes shape to make the rubber ring 5 more tightly contact the inner wall of the bottle body 1. A first bolt 4 is provided inside the expansion tube 3, which, in conjunction with the expansion tube 3, improves the sealing effect of the rubber ring 5. A rubber ring 5 is fixedly installed outside the expansion tube 3, achieving a seal. A fixing ring 6 is provided above the rubber ring 5, which continuously provides pressure to the rubber ring 5. Two second bolts 7 are provided inside the bottle cap 2, which can compress the fixing ring 6.
[0023] Specifically, the first bolt 4 has an external thread on its outside, and the expansion tube 3 has an internal bolt inside. The first bolt 4 is threadedly connected to the expansion tube 3. When the first bolt 4 is threadedly connected to the expansion tube 3, the state of the expansion tube 3 can be changed by using the first bolt 4.
[0024] Specifically, the lower end of the second bolt 7 is in close contact with the upper surface of the fixing ring 6, one end of the expansion tube 3 extends into the interior of the bottle body 1, and the outer surface of the rubber ring 5 is in close contact with the inner wall of the bottle body 1. When the outer surface of the rubber ring 5 is in close contact with the inner wall of the bottle body 1, a sealing effect can be achieved.
[0025] Specifically, a first buckle 8 is provided on the outside of the bottle body 1, and a second buckle 9 is fixedly installed above the first buckle 8. The second buckle 9 is located on the outside of the bottle cap 2. The bottle body 1 and the bottle cap 2 are fixed together by the first buckle 8 and the second buckle 9. The first buckle 8 includes a first arc-shaped clamp 10, a second arc-shaped clamp 11, a first fixing plate 12, a second fixing plate 13, a movable rod 14, and a first nut 15. The second arc-shaped clamp 11 is hinged to one end of the first arc-shaped clamp 10, which facilitates the overall connection between the bottle body 1 and the bottle cap 2. The first fixing plate 12 is fixedly installed to one end of the first arc-shaped clamp 10. Plate 12 facilitates the movement of movable rod 14. Movable rod 14 is hinged inside the first fixed plate 12, allowing the first arc-shaped clamping plate 10 and the second arc-shaped clamping plate 11 to be fixedly connected via movable rod 14. A second fixed plate 13 is fixedly installed on one side of the second arc-shaped clamping plate 11, facilitating the threaded connection between the first nut 15 and movable rod 14 via the second fixed plate 13. The first nut 15 is provided on the outside of movable rod 14, facilitating the connection between the first arc-shaped clamping plate 10 and the second arc-shaped clamping plate 11 via the first nut 15. The second buckle 9 includes a third arc-shaped clamping plate 16, a fourth arc-shaped clamping plate 17, a first support plate 18, a second support plate 19, and a third bolt 2. 0. The second nut 21 and the third arc-shaped clamping plate 16 are hinged at one end to a fourth arc-shaped clamping plate 17, which further stabilizes the bottle cap 2. The other end of the third arc-shaped clamping plate 16 is fixedly mounted with a first support plate 18, which facilitates the threaded connection between the second nut 21 and the third bolt 20. One end of the fourth arc-shaped clamping plate 17 is fixedly mounted with a second support plate 19, which supports the third bolt 20 for operation. The third bolt 20 is located inside the second support plate 19, which facilitates the connection between the third arc-shaped clamping plate 16 and the fourth arc-shaped clamping plate 17. The third bolt 2... A second nut 21 is provided on the outside of the bottle body 1. The second nut 21 is used to fix the third arc-shaped clamp 16 and the fourth arc-shaped clamp 17 together. The inner rings of the first arc-shaped clamp 10 and the second arc-shaped clamp 11 are in close contact with the outer surface of the bottle body 1. When the inner rings of the first arc-shaped clamp 10 and the second arc-shaped clamp 11 are in close contact with the outer surface of the bottle body 1, the connection between the bottle body 1 and the bottle cap 2 can be strengthened. The inner walls of the third arc-shaped clamp 16 and the fourth arc-shaped clamp 17 are in close contact with the outer surface of the bottle cap 2. When the inner walls of the third arc-shaped clamp 16 and the fourth arc-shaped clamp 17 are in close contact with the outer surface of the bottle cap 2, the bottle cap 2 can be fixed more firmly.
[0026] Specifically, the first arc-shaped clamp 10 is fixedly connected to the third arc-shaped clamp 16, and the second arc-shaped clamp 11 is fixedly connected to the fourth arc-shaped clamp 17. By fixing the first arc-shaped clamp 10 to the third arc-shaped clamp 16 and the second arc-shaped clamp 11 to the fourth arc-shaped clamp 17, the first buckle 8 and the second buckle 9 can form a whole.
[0027] Working principle: When the bottle cap 2 is threadedly connected to the bottle body 1, one end of the expansion tube 3 extends into the interior of the bottle body 1. The rubber ring 5 on its outside is in close contact with the inner wall of the bottle body 1, initially forming a sealing barrier at the bottle opening to prevent external moisture and oxygen from entering. The first bolt 4 is threadedly connected to the expansion tube 3. By rotating the first bolt 4, its position within the expansion tube 3 can be changed, thereby adjusting the state of the expansion tube 3 and enhancing the fit between the rubber ring 5 and the inner wall of the bottle body 1, improving the sealing effect. The second bolt 7 is located inside the bottle cap 2, with its lower end in close contact with the upper surface of the fixing ring 6. When the second bolt 7 is tightened, it presses downwards against the fixing ring 6, applying continuous pressure to the rubber ring 5 to prevent it from loosening due to long-term use, further ensuring... To ensure the reliability of the seal, the first arc-shaped clamping plate 10 and the second arc-shaped clamping plate 11 of the first buckle 8 are fixed to the bottle cap 2 by the cooperation of the movable rod 14 and the first nut 15 on the first fixed plate 12 and the second fixed plate 13, tightly fitting the outside of the bottle body 1. The third arc-shaped clamping plate 16 and the fourth arc-shaped clamping plate 17 of the second buckle 9 are fixed to the outside of the bottle cap 2 by the cooperation of the third bolt 20 and the second nut 21 on the first support plate 18 and the second support plate 19, firmly fixing them to the outside of the bottle cap 2, providing a foundation for subsequent overall reinforcement. Since the first buckle 8 and the second buckle 9 are fixedly connected to form an integral structure, on the basis of the threaded connection between the bottle cap 2 and the bottle body 1, the bottle cap 2 and the bottle body 1 can be further reinforced together to prevent the bottle cap 2 from loosening due to vibration or collision during transportation or use.
