Description

Technical Field

[0001] This invention relates to the field of reagent kits, and more specifically, to a reagent kit with a single-opening and closing mechanism for a multi-reagent tube containing cavity. Background Technology

[0002] In fields such as biological detection, clinical diagnosis, and chemical experiments, it is often necessary to use reagent kits that can hold multiple reagent tubes to store different types of reagents in order to meet the need for continuity of experimental operations.

[0003] However, the opening and closing structures of existing multi-tube reagent kits have significant shortcomings: some kits use a design where each reagent tube has an independent sealing cap, which allows for individual sealing of each tube, but requires repeatedly opening and closing multiple caps when using different reagents during the experiment, making the operation cumbersome and prone to cap loss; other kits use an integrated large cap structure that seals all reagent tube chambers uniformly, which simplifies the opening and closing operation, but each time the large cap is opened, all reagent tube chambers are exposed to the external environment, which can affect the reagents in other unused tubes (e.g., light, dust intrusion, temperature, etc.), directly threatening reagent performance, experimental safety, and the accuracy of results.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a reagent kit with a single opening and closing of a multi-reagent tube containing cavity. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a reagent kit with a single opening and closing mechanism for a multi-reagent tube containing cavity.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reagent kit with a single-opening and closing multi-reagent tube containing cavity, comprising: A cylindrical slot has multiple reagent tube receiving cavities arranged in a circumferential array inside; The rotating cap is installed on the cylindrical slot seat and has a through groove on the top. After installation, the rotating cap can rotate along the cylindrical slot seat to align the through groove with different reagent tube receiving cavities in turn, so as to open the different reagent tube receiving cavities. A sealing cap, which covers the through groove to seal it.

[0007] Preferably, an annular track is fixedly connected to the outer side wall of the cylindrical groove near the bottom end, and a slider is slidably connected to the top end of the annular track. The slider is detachably connected to the bottom of the rotating cover.

[0008] Preferably, there are four sliders, which are evenly distributed on the circular track and connected to each other as a whole by connecting plates.

[0009] Preferably, a screw is fixedly connected to the top of the slider, and four mounting plates arranged in a circular array and corresponding one-to-one with the slider are fixedly connected to the outer side wall of the rotating cover near the bottom. The mounting plates are provided with through holes for the screw to pass through, and a nut is threaded onto the outer side wall of the screw.

[0010] Preferably, multiple indicator plates arranged in a circumferential array are fixedly connected to the outer wall of the rotating cap. The area between two indicator plates corresponds to a reagent tube receiving cavity. According to the guidance of the indicator plates, the operator can easily align the through groove with different reagent tube receiving cavities.

[0011] Preferably, the top of the rotating cover has a raised edge integrally formed around the through groove, and the closing cover closes the through groove by being inserted into the raised edge.

[0012] Preferably, sealing rubber A is adhered to the inner wall of the rotating cover, and sealing rubber B is adhered to the inner wall of the closed cover.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model features a rotating cap mounted on a cylindrical slot, which precisely aligns the through-slot at the top of the rotating cap with the reagent tube cavity containing the target reagent tube. After opening the sealing cap on the through-slot, the reagent in the target reagent tube can be retrieved through the through-slot. After retrieval, the sealing cap is resealed on the through-slot to seal the reagent tube cavity. To retrieve other reagents, simply rotate the rotating cap again, aligning the through-slot with the cavities of other target reagent tubes in sequence, and then open the sealing cap. During this process, the reagent tube cavities not aligned with the through-slot are always blocked by the rotating cap, effectively preventing the influence of external light, dust intrusion, temperature changes, and other factors on unused reagents. Furthermore, it eliminates the need for repeated operation of multiple independent sealing caps, solving the problems of cumbersome operation, easy cap loss, or susceptibility of unused reagents to external interference in existing reagent kits. 2. The detachable design between the slider and the bottom of the rotating cover in this utility model means that when the rotating cover is worn or damaged, the staff does not need to replace the entire reagent kit, but only needs to disassemble and replace the faulty part, which effectively reduces the cost of using and maintaining the reagent kit.

[0014] 3. The four sliders of this utility model, which are evenly distributed on the annular track, can evenly distribute the weight of the rotating cover and the force generated during rotation to the four points of the annular track, avoiding premature wear of the sliders or the annular track due to local force concentration. At the same time, the four-point support structure greatly improves the stability of the fit between the rotating cover and the cylindrical groove seat, effectively preventing the rotating cover from tilting, shaking or shifting during rotation.

[0017] like Figure 1-5 As shown, this utility model provides a reagent kit with a single-opening and closing multi-reagent tube containing cavity, comprising: A cylindrical groove 1 has multiple reagent tube receiving cavities 101 arranged in a circular array inside it; The rotating cover 2 is installed on the cylindrical groove seat 1 and has a through groove 201 on the top. After installation, the rotating cover 2 can rotate along the cylindrical groove seat 1 to align the through groove 201 with different reagent tube receiving cavities 101 in sequence, so as to open different reagent tube receiving cavities 101. The sealing cover 3 covers the through groove 201 and is used to seal the through groove 201.

[0018] First, each reagent tube is placed in a circular array within the cylindrical base 1 into one of the multiple reagent tube receiving cavities 101. Then, the rotating cap 2 is installed onto the cylindrical base 1. Normally, the sealing cap 3 closes onto the through-slot 201 at the top of the rotating cap 2, achieving an initial seal for all reagent tube receiving cavities 101. When a specific reagent needs to be retrieved, the rotating cap 2 is rotated on the cylindrical base 1, precisely aligning the through-slot 201 at the top of the rotating cap 2 with the reagent tube receiving cavity 101 containing the target reagent tube. Then, the sealing cap 3, which closes onto the through-slot 201, is opened, allowing the reagent in the target reagent tube to be retrieved through the through-slot 201. After use, the sealing cap 3 is reattached to the through slot 201 to seal the reagent tube receiving cavity 101. If other reagents need to be used, simply rotate the rotating cap 2 again to align the through slot 201 with the other target reagent tube receiving cavities 101 in sequence, and then open the sealing cap 3. During this process, the reagent tube receiving cavities 101 that are not aligned with the through slot 201 are always blocked by the rotating cap 2, which effectively avoids the influence of external light, dust intrusion, temperature changes and other factors on unused reagents. At the same time, it eliminates the need to repeatedly operate multiple independent sealing caps, solving the problems of cumbersome operation, easy loss of caps or easy external interference of unused reagents in existing reagent kits.

[0019] The rotating cover 2 has an integrally formed raised edge 202 around the top of the through groove 201. The closing cover 3 closes the through groove 201 by inserting it into the raised edge 202. A sealing rubber A203 is bonded to the inner wall of the rotating cover 2 (because it will be subject to friction when the rotating cover 2 rotates relative to the cylindrical groove seat 1, a friction-resistant and anti-aging rubber material is preferred). A sealing rubber B301 is bonded to the inner wall of the closing cover 3. The integrally formed raised edge 202 around the top of the rotating cover 2 around the through groove 201 provides a precise insertion and positioning structure for the closing cover 3, allowing the closing cover 3 to quickly close the through groove 201 through insertion. This is convenient and provides a stable connection. Meanwhile, the sealing rubber A203 on the inner wall of the rotating cover 2... It can fit tightly against the outer wall of the cylindrical slot 1, filling the gap between the two and preventing external dust and moisture from entering through the mating point between the rotating cap 2 and the cylindrical slot 1. The sealing rubber B301 on the inner wall of the sealing cap 3 can make close contact with the inner side of the protrusion 202 after insertion, further enhancing the sealing effect between the sealing cap 3 and the protrusion 202. The double sealing structure together improves the sealing performance of the entire reagent kit, effectively isolating external light, dust, temperature changes and other interference factors, and better ensuring the stability of the reagents in the reagent tube.

[0020] Furthermore, multiple indicator plates 4 arranged in a circumferential array are fixedly connected to the outer wall of the rotating cover 2. The area between two indicator plates 4 corresponds to a reagent tube receiving cavity 101. According to the guidance of the indicator plates 4, the staff can easily align the through slot 201 with different reagent tube receiving cavities 101. The staff does not need to rely on experience or repeated trial and error. They can quickly identify the rotating area corresponding to the target reagent tube receiving cavity 101 by simply using the indicator plates 4, and easily and accurately align the through slot 201, reducing the inconvenience of taking out the reagent tube due to alignment deviation or opening other reagent tube receiving cavities 101 that are not needed.

[0021] Finally, this utility model provides a specific structure for the rotating cover 2 to rotate around the cylindrical groove seat 1: an annular track 102 is fixedly connected to the outer side wall of the cylindrical groove seat 1 near the bottom end, and a slider 103 is slidably connected to the top end of the annular track 102, and the slider 103 is detachably connected to the bottom of the rotating cover 2.

[0022] In use, the bottom of the rotating cover 2 is connected to the slider 103. When the rotating cover 2 rotates, it will drive the slider 103 to rotate around the annular track 102. This provides a stable circular motion trajectory for the rotation of the rotating cover 2, avoiding deviation, shaking or jamming of the rotating cover 2 during rotation. It ensures that the rotating cover 2 can rotate smoothly and stably around the cylindrical slot 1. The detachable design means that when the rotating cover 2 is worn or damaged, the staff does not need to replace the entire reagent kit. They only need to disassemble and replace the faulty part, which effectively reduces the cost of using and maintaining the reagent kit.

[0023] Furthermore, there are four sliders 103, which are evenly distributed on the annular track 102 and connected to each other by a connecting plate 104 (the connecting plate 104 maintains the even distribution of the sliders 103). The four sliders 103 evenly distributed on the annular track 102 can evenly distribute the weight of the rotating cover 2 and the force generated during rotation to four points on the annular track 102, avoiding premature wear of the sliders 103 or the annular track 102 due to local force concentration. At the same time, the four-point support structure greatly improves the stability of the fit between the rotating cover 2 and the cylindrical groove seat 1, effectively preventing the rotating cover 2 from tilting, shaking or shifting during rotation.

[0024] This utility model also provides a specific structure for the detachable connection between the slider 103 and the bottom of the rotating cover 2: the top of each slider 103 is fixedly connected with a screw 5, and the outer side wall of the rotating cover 2 is fixedly connected with four mounting plates 6 arranged in a circumferential array and corresponding one-to-one with the slider 103 near the bottom. Each mounting plate 6 has a through hole 601 for the screw 5 to pass through, and a nut 7 is threaded onto the outer side wall of each screw 5.

[0025] During installation, the operator first inserts the rotating cover 2 into the cylindrical slot 1 (before insertion, the through holes 601 on the four mounting plates 6 arranged in a circular array at the bottom of the rotating cover 2 and corresponding one-to-one with the slider 103 are aligned with the screws 5 fixed at the top of each slider 103). The sealing rubber A203 on the inner side wall of the rotating cover 2 contacts the outer side wall of the cylindrical slot 1. At the same time, each screw 5 is passed through the through hole 601 of the mounting plate 6 above it. Then, the nuts 7 are threaded onto the outer side wall of each screw 5. The nuts 7 are turned clockwise until they fit tightly against the mounting plate 6, thus completing the fixed installation of the slider 103 and the rotating cover 2. During disassembly, the operator only needs to turn the nuts 7 on each screw 5 counterclockwise. After all the nuts 7 are completely removed from the screws 5, the rotating cover 2 is gently lifted upwards to disengage the through holes 601 of the mounting plate 6 from the screws 5, thus separating and disassembling the slider 103 from the rotating cover 2.
