[0002] Biological reagents refer to biological materials or organic compounds related to life science research, as well as reagents for clinical diagnosis and medical research. Biological reagents can be roughly divided into solid reagents and liquid reagents according to their physical forms. Solid reagents are generally contained in wide-mouth bottles with bakelite stoppers, while liquid reagents are contained in narrow-mouth bottles. Reagents that are easily decomposed by light need to be contained in brown bottles, and each reagent is labeled to indicate the name, concentration, and purity of the reagent. During the production process of biological reagents, sampling is required, and the extracted samples need to be properly preserved using a preservation device and then transferred to a testing room for testing.

[0003] When the existing biological reagent sample preservation device is in use, it can usually only reliably fix biological sample reagent bottles of a single or several specifications and sizes, and has the disadvantage of narrow applicability.

Specific embodiments

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Please refer to Figures 1-8。The preservation device for biological reagent samples includes: a box body 1 and a box cover 2. The box cover 2 is rotatably installed on the box body 1. A box lock is provided between the box cover 2 and the box body 1. A handle is fixedly installed on the top of the box cover 2 for facilitating the opening of the box cover 2. A fixing plate 3 is fixedly installed inside the box body 1. Multiple internal thread grooves 301 are formed on the fixing plate 3. A push ring 4 is threadedly installed in the internal thread grooves 301. External threads are provided on the outer wall of the push ring 4, which are screwed with the internal threads formed on the inner wall of the internal thread grooves 301. Multiple clamping strips 5 distributed in a circular array are arranged inside the push ring 4. The clamping strips 5 are used for clamping and fixing the biological reagent sample bottles. A circular through-hole is formed on the bottom inner wall of the internal thread grooves 301. The bottom end of the clamping strip 5 passes through the circular through-hole and extends below the fixing plate 3. An inclined rod 6 is fixedly installed on the clamping strip 5 and is in contact with the push ring 4. A hexagonal sliding rod 7 is fixedly installed on the clamping strip 5. Multiple limiting blocks 9 are fixedly installed on the bottom of the fixing plate 3. Multiple hexagonal sliding rods 7 all penetrate through the corresponding limiting blocks 9 and are slidably connected with the corresponding limiting blocks 9. Due to the limitation of the limiting blocks 9, the clamping strip 5 can only move horizontally. One end of the hexagonal sliding rod 7 away from the clamping strip 5 is fixedly installed with an end plate 10. A compression spring 11 is sleeved on the hexagonal sliding rod 7. One end of the compression spring 11 is fixedly connected with the limiting block 9, and the other end is fixedly connected with the end plate 10. Multiple hand rods 12 are fixedly installed on the top of the push ring 4. The push ring 4 is rotated through the hand rods 12. During the process of the push ring 4 rotating clockwise, it will move upward. During the upward movement of the push ring 4, its inner ring will contact the corresponding multiple inclined rods 6. Under the push of the horizontal component of the contact force, the clamping strip 5 moves towards the center position of the internal thread grooves 301. Under the combined action of multiple clamping strips 5, the biological reagent sample bottle can be clamped.

[0024] In this embodiment, in order to preserve a biological reagent sample that needs to be stored at low temperature, two ice bag placement openings 302 are formed on the fixing plate 3. Two ice bag frames 16 are fixedly installed on the bottom of the fixing plate 3, and both ice bag frames 16 communicate with the corresponding ice bag placement openings 302. The bottom of the ice bag frames 16 is fixedly connected with the bottom inner wall of the box body 1. Multiple ventilation holes are formed on the ice bag frames 16, and the cold air emitted from the ice bags can escape through the ventilation holes.

[0025] In this embodiment, in order to increase the reliability of fixing the biological reagent sample bottle and at the same time provide the same protection for the biological reagent sample bottle, a rubber strip 8 is fixedly installed on the outer wall of the clamping strip 5 away from the inclined rod 6.

[0026] In this embodiment, in order to fix reagent sample bottles at different depths within a certain range, a plurality of adjusting screws 14 are threadedly installed on the bottom inner wall of the box body 1. The bottom ends of the adjusting screws 14 extend below the box body 1, and the top ends of the adjusting screws 14 are rotatably sleeved with depth support plates 13. Three limiting slide bars 15 are fixedly installed at the bottom of the depth support plates 13. The bottom ends of the three limiting slide bars 15 all extend below the box body 1, and the limiting slide bars 15 are slidably connected to the box body 1. When the adjusting screws 14 are rotated clockwise or counterclockwise, they can move upward or downward, and then drive the depth support plates 13 to rise or fall. In this way, the distance between the depth support plates 13 and the fixing plates 3 can be adjusted. In this way, when the reagent sample bottles are relatively low, the depth support plates 13 can be correspondingly raised so that the reagent sample bottles can be placed at a relatively high position after being placed in the internal thread grooves 301. On the one hand, the reagent sample bottles can be reliably clamped and fixed, and on the other hand, it is convenient to take them. Conversely, when the reagent sample bottles are relatively high, the depth support plates 13 are correspondingly lowered.

[0027] In this embodiment, a corrugated pipe 17 is fixedly installed at the bottom of the depth support plate 13. The corresponding three limiting slide bars 15 and adjusting screws 14 are all located inside the corrugated pipe 17. The bottom of the corrugated pipe 17 is fixedly connected to the bottom inner wall of the box body 1. Through the setting of the corrugated pipe 17, it is possible to prevent the water condensed from the air in the box body 1 from leaking out randomly from the threaded holes where the adjusting screws 14 are located and the sliding holes where the limiting slide bars 15 are located. A drain port is opened at the rear side of the box body 1, and the drain port is blocked by a rubber plug. The rubber plug can be pulled out to drain water.

[0028] In this embodiment, when placing the reagent sample bottles, in order to prevent the sample bottles from colliding with the depth support plates 13, rubber pads are fixedly installed at the tops of the depth support plates 13.

[0029] The working principle of the preservation device for reagent samples provided by the present utility model is as follows:

[0030] In the initial state, the push ring 4 is located at the lowest position, and the compression spring 11 is in a compressed state. The compression spring 11 gives an elastic force to the end plate 10, and this elastic force acts on the clamping strip 5 through the hexagonal slide bar 7, so that the inclined rod 6 on the clamping strip 5 is in contact with the inner ring of the push ring 4; during use, first adjust the height of the depth support plate 13 according to the height of the reagent sample bottle. During adjustment, rotate the adjusting screw 14 clockwise or counterclockwise. During the clockwise or counterclockwise rotation of the adjusting screw 14, it will move upward or downward, and during the movement of the adjusting screw 14, it will drive the depth support plate 13 to move correspondingly, so that the height position of the depth support plate 13 can be adjusted appropriately;

[0031] After the height adjustment of the depth support plate 13 is completed, the biological reagent sample bottles are placed one by one in the center of the multiple internal thread grooves 301, supported by the corresponding depth support plate 13, and then the push ring 4 is rotated clockwise one by one. The push ring 4 will move upward during the clockwise rotation. During the rising process of the push ring 4, the multiple inclined rods 6 will be pushed through its inner ring. The inclined rods 6 drive the clamping strips 5 to move accordingly, so that the multiple clamping strips 5 move toward the center direction of the internal thread groove 301 at the same time (the compression spring 11 will be further compressed during this process). Finally, the multiple clamping strips 5 cooperate to clamp the biological reagent sample bottle. Since the multiple clamping strips 5 are simultaneously gathered toward the center direction of the internal thread groove 301 to achieve fixation, sample bottles of different diameters can be fixed within a certain range. If the biological reagent samples need to be refrigerated, ice bags can be inserted into the two ice bag frames 16;

[0032] When it is necessary to take out the biological reagent sample bottle, it is only necessary to rotate the push ring 4 in the opposite direction. The push ring 4 will move downward during the reverse rotation. During its descent, the compression spring 11 will push the end plate 10 away from the sample bottle. The end plate 10 drives the clamping strip 5 to move accordingly through the hexagonal sliding rod 7, so that the clamping strip 5 is away from the sample bottle at night. After the clamping strip 5 loses its clamping, the sample bottle can be easily taken out.

[0033] Compared with the related art, the biological reagent sample storage device provided by the utility model has the following beneficial effects:

[0034] The utility model provides a storage device for biological reagent samples. Through the arrangement of components such as a fixing plate 3, a push ring 4, a clamping strip 5, an inclined rod 6, an inner hexagonal sliding rod 7, a rubber strip 8, a limiting block 9, an end plate 10, and a compression spring 11, when in use, after placing a biological reagent sample bottle in an inner thread groove 301, it is only necessary to rotate the push ring 4 clockwise to simultaneously close the corresponding plurality of clamping strips 5, and finally clamp and fix the biological reagent sample bottle. The utility model is not only simple to operate, but also can fix biological reagent sample bottles of different diameters within a certain range. Through the arrangement of a depth support plate 13, an adjusting screw 14, and a limiting sliding rod 15, when the adjusting screw 14 is rotated clockwise or counterclockwise, the height position of the depth support plate 13 can be adjusted, and within a certain range, biological reagent sample bottles of different heights can all obtain a more appropriate support height. The utility model has the advantages of simple operation and wide application range.
