Description

Technical Field

[0001] The utility model relates to the technical field of chemical storage devices, in particular to a D-galactose storage bottle. Background Art

[0002] D-galactose is a chemical substance. It is a right-handed six-carbon aldose obtained by hydrolyzing lactose. Its chemical formula is C6H12O6. It appears as white crystals or crystalline powder with no special odor. It is soluble in water and pyridine, with a solubility in water of 680g / L (25°C); it is slightly soluble in glycerol and alcohol. D-galactose is a component of sugars such as agar, plant gums, viscose, raffinose, lactose, and melibiose. It exists in animal materials such as snail protein glands, frog eggs, and brain nerve tissue as galactoside and galactose anhydride molecules. The storage conditions of D-galactose should be sealed and stored in a dark, dry and cool place. It is strictly forbidden to mix or transport it with toxic or harmful items.

[0003] However, the top of the existing D-galactose storage bottle is open and sealed by a sealing plug or a lid. When sampling D-galactose, the sealing plug or the lid needs to be opened. During the sampling process, the sealing state of the storage bottle disappears, allowing foreign matter to enter the storage bottle during the sampling process, resulting in the risk of D-galactose being contaminated. Therefore, it does not meet the existing needs. In this regard, we have proposed a D-galactose storage bottle. Utility Model Content

[0004] The purpose of the utility model is to provide a D-galactose storage bottle to solve the problems proposed in the above-mentioned background technology, such as the top of the D-galactose storage bottle is an open opening, which is sealed by a sealing plug or a lid. When D-galactose is sampled, the sealing plug or the lid needs to be opened, and the sealing state of the storage bottle disappears during the sampling process, so that foreign matter enters the interior of the storage bottle during the sampling process, resulting in the risk of contamination of D-galactose.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a D-galactose storage bottle, comprising a storage bottle body, a storage bin and a guide sampling slot provided inside the storage bottle body, the guide sampling slot and the storage bin bracket are provided with a circular partition and the partition is fixed to the inner wall of the storage bottle body, the top of the guide sampling slot is open and flush with the upper surface of the storage bottle body, a sampling notch is provided in the middle and upper part of the partition to connect the guide sampling slot and the storage bin, a sampling rod is slidably installed on the inner side of the guide sampling slot, a sample storage bin is provided inside the bottom end of the sampling rod, a feeding notch is provided on one side of the top of the sample storage bin, and a sealing block is also slidably installed on the inner side of the guide sampling slot.

[0006] Preferably, the outer diameter of the sealing block is consistent with the inner diameter of the guide sampling slot and the sealing block is made of rubber. A sealing spring is installed between the bottom end of the sealing block and the bottom surface of the guide sampling slot.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] like Figures 1 to 4 As shown, a D-galactose storage bottle is provided, wherein a storage bin 5 and a guide sampling slot 3 are provided inside the storage bottle body 1, a circular partition is provided between the guide sampling slot 3 and the storage bin 5 bracket, and the partition is fixed to the inner wall of the storage bottle body 1, the top of the guide sampling slot 3 is open and flush with the upper surface of the storage bottle body 1, a sampling notch 4 is provided in the middle and upper part of the partition to connect the guide sampling slot 3 and the storage bin 5, a sampling rod 2 is slidably installed on the inner side of the guide sampling slot 3, and a sample storage bin 8 is provided inside the bottom end of the sampling rod 2, and the sample storage A feeding notch 9 is provided on one side of the top of the bin 8, and a sealing block 6 is slidably installed on the inner side of the guide sampling groove 3 to store D-galactose in the storage bin 5. Then, the sampling rod 2 slides in the guide sampling groove 3 and presses the sealing block 6 downward, so that the feeding notch 9 is aligned with the sampling notch 4 and the sample storage bin 8 is connected to the storage bin 5, so that the D-galactose stored in the storage bin 5 enters the sample storage bin 8, and then the sampling rod 2 is removed from the guide sampling groove 3 to achieve sampling of D-galactose;

[0021] The storage bottle body 1 includes a top cover, a bottom plate and an intermediate bottle body. The top cover and the bottom plate are respectively located on the inner side of the top end and the inner side of the bottom end of the intermediate bottle body. The top cover and the intermediate bottle body are opaque, and the bottom plate is transparent. The opacity of the top cover and the intermediate bottle body can ensure that D-galactose is stored under light-shielding conditions, and the transparent bottom plate makes it convenient for staff to observe the inside of the storage bottle body 1 when sampling, ensuring that the feed notch 9 is smoothly aligned with the sampling notch 4.

[0022] The outer diameter of the sealing block 6 is consistent with the inner diameter of the guide sampling groove 3 and the sealing block 6 is made of rubber. A sealing spring 7 is installed between the bottom end of the sealing block 6 and the bottom surface of the guide sampling groove 3. When the sealing block 6 is in the initial position, the top end of the sealing block 6 is higher than the top edge of the feed notch 9, and the bottom end of the sealing block 6 is lower than the bottom edge of the sealing block 6. The two ends of the sealing spring 7 are respectively fixed to the bottom end of the sealing block 6 and the ground of the guide sampling groove 3. The sealing spring 7 is used to support the sealing block 6 to ensure that the sealing block 6 closes the feed notch 9, so that the storage bin 5 is always in a sealed state.

[0023] A sealing ring groove 11 is provided on the outer surface of the sampling rod 2. The interface of the sealing ring groove 11 is U-shaped. The inner side of the sealing ring groove 11 is filled with a sealing ring 10. The sealing ring 10 is made of rubber and is hollow inside. The radius of the sealing ring 10 is larger than the cross-sectional width of the sealing ring groove 11. The sealing ring 10 is used to seal the gap between the sampling rod 2 and the inner wall of the guide sampling groove 3, and to increase the friction resistance between the sampling rod 2 and the inner wall of the guide sampling groove 3, to ensure that the sampling rod 2 will not slide inside the guide sampling groove 3 without human intervention, thereby preventing the sampling rod 2 from falling from the storage bottle 1.

[0024] Working principle: When taking out the D-galactose stored in the storage bin 5, the staff needs to pick up the storage bottle 1 and tilt the storage bottle 1 as a whole toward the sampling slot 3. At this time, the staff squeezes the sampling rod 2 toward the inside of the sampling slot 3, so that the sampling rod 2 pressurizes the sealing block 6 so that the sealing block 6 is misaligned with the feed notch 9, and the sealing spring 7 is compressed until the feed notch 9 on the top side of the sample storage bin 8 is aligned with the sampling notch 4. At this time, the sample storage bin 8 is aligned with the storage bin 5 through the sampling notch 4, the feed notch 9 and the storage bin 5. The staff shakes the storage bottle 1 to send the D-galactose stored in the storage bin 5 through the sampling gap 4 and the feed gap 9 into the sample storage bin 8. After the sample storage bin 8 is filled with a sufficient amount of D-galactose, the staff only needs to pull out the sampling rod 2 upwards. At this time, the sealing spring 7 drives the sealing block 6 to reset. During the reset process, the sealing block 6 re-seals the feed gap 9. The storage bin 5 is always in a sealed state during the entire sampling process, preventing foreign matter from entering the storage bin 5 during the sampling process and contaminating the D-galactose.

[0025] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
