Technical Field

[0001] This utility model relates to the field of nucleic acid extraction technology, and more specifically, to a turntable device for a nucleic acid extractor. Background Technology

[0002] Nucleic acid extractors are instruments that use matching nucleic acid extraction reagents to automatically complete the extraction of nucleic acids from samples. They are widely used in various fields such as disease control centers, clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbiology testing, food safety testing, animal husbandry, and molecular biology research.

[0003] In existing technologies, the turntable of a nucleic acid extractor needs to support multiple deep well plates to achieve high-throughput sample processing. However, current turntable devices generally use simple slots or clamps to fix the deep well plates, which may result in problems such as insecure installation, easy detachment, or displacement during high-speed rotation. In addition, existing turntables mostly adopt an integral structure, and when the connecting component of a single well is damaged, the entire turntable needs to be replaced, which significantly increases maintenance costs.

[0004] Therefore, a turntable device for a nucleic acid extractor is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a turntable device for a nucleic acid extractor to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A turntable device for a nucleic acid extractor includes a turntable body. The turntable body has several mounting slots arranged in a circular array. The cross-section of each mounting slot is rectangular and each of its four walls is detachably connected to a snap-fit ​​component. Several bearing portions are fixedly connected to the bottom of the inner wall of the mounting slot. The snap-fit ​​components and the bearing portions are alternately arranged.

[0008] The technical solution of this utility model is further configured as follows: the snap-fit ​​component includes an elastic element one for preventing the deep hole plate from disengaging and an elastic element two for embedding into the groove of the deep hole plate. The elastic element one is located on a pair of opposing inner walls of the mounting groove, and the elastic element two is located on another pair of opposing inner walls of the mounting groove.

[0009] The technical solution of this utility model is further configured as follows: the bottom end of the first elastic element is L-shaped, the top end of the first elastic element has a protrusion facing the inside of the mounting groove, the bottom surface of the turntable body is provided with a fitting groove, and the bottom end of the first elastic element is located in the fitting groove.

[0010] The technical solution of this utility model is further configured such that the number of elastic elements on one side of the inner wall of the mounting groove is greater than the number of elastic elements on the opposite side of the inner wall.

[0011] The technical solution of this utility model is further configured as follows: the second elastic member is located below one of the bearing portions and its two ends extend from the two ends of the bearing portion; the two ends of the second elastic member in the length direction are arc-shaped embedding portions; and the inner wall of the mounting groove is provided with a groove for accommodating the embedding portion.

[0012] The technical solution of this utility model is further configured as follows: a receiving groove is provided on the bottom surface of the bearing part corresponding to the second elastic element, a pad is provided below the second elastic element, the second elastic element and the pad are located in the receiving groove, and corresponding positioning holes are provided on the bearing part, the second elastic element and the pad, and the positioning holes on the second elastic element are elongated.

[0013] The technical solution of this utility model is further configured such that the width of the embedded part is smaller than the width of the center of the second elastic member.

[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0015] The structure allows the deep hole plate to be quickly installed on the turntable body, and the snap-fit ​​parts simultaneously limit the four sides of the bottom of the deep hole plate to ensure that it is firmly installed and not easy to fall off, thus preventing displacement during high-speed rotation. Moreover, since both elastic element one and elastic element two are designed to be detachable, they can not only be adjusted according to actual needs, but also be replaced to meet the needs of different situations.

[0016] By setting up elastic element one, the bottom two sides of the deep well plate can be restricted by the protrusion, thus ensuring the stability of the deep well plate installation. Elastic element two is used to embed into the notch on the bottom of the deep well plate. Its arc design enhances the buffering effect and reduces the shaking of the deep well plate on the turntable body when the nucleic acid extractor is working. At the same time, it can also enhance the fixing effect on the other two sides of the bottom of the deep well plate, so that all four sides of the bottom of the deep well plate are restricted, ensuring that it is sufficiently stable after installation.

[0022] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model. Example

[0023] refer to Figures 1 to 4 As shown, this utility model provides a turntable device for a nucleic acid extractor, including a turntable body 1. The turntable body 1 has several mounting slots 2 arranged in a circular array. The cross-section of the mounting slots 2 is rectangular and each of its four walls can be detachably connected with a snap-fit ​​component. Several bearing parts 3 are fixedly connected to the bottom of the inner wall of the mounting slot 2. The snap-fit ​​components and the bearing parts 3 are alternately arranged. The snap-fit ​​components include an elastic element 4 for preventing the deep well plate from detaching and an elastic element 5 for embedding into the slot of the deep well plate. The elastic element 4 is located on a pair of opposite inner walls of the mounting slot 2, and the elastic element 5 is located on another pair of opposite inner walls of the mounting slot 2.

[0024] refer to Figures 1 to 4 As shown, the bottom end of the elastic element 4 is L-shaped, and the top end of the elastic element 4 has a protrusion 6 facing the inside of the mounting groove 2. The protrusion 6 is formed by bending the elastic element 4. The bottom surface of the turntable body 1 has a fitting groove 7. The bottom end of the elastic element 4 is located in the fitting groove 7 and is installed by screws. The number of elastic elements 4 on one side of the inner wall of the mounting groove 2 is greater than the number of elastic elements 4 on the opposite side of the inner wall. Through the design of the above structure, after the elastic element 4 is installed in the fitting groove 7, its top end will extend from between the adjacent bearing parts 3. It uses the protrusion 6 facing the inside of the mounting groove 2 to contact the bottom end of the deep hole plate. When the deep hole plate is installed, the elastic element 4 deforms in the outward direction, allowing the deep hole plate to enter the mounting groove 2 and its bottom edge to be located on the bearing part 3. After installation, the protrusion 6 of the elastic element 4 is located above the outer extension of the bottom end of the deep hole plate, which plays a role in restricting detachment. The above number setting allows the deep hole plate to be disassembled from the side with less restrictive force when it is necessary to remove the deep hole plate, making it easier to remove the deep hole plate.

[0025] refer to Figures 1 to 4As shown, the second elastic element 5 is located below a support portion 3, with both ends extending from the two ends of the support portion 3. The two ends of the second elastic element 5 in the length direction are arc-shaped insert portions 8. The inner wall of the mounting groove 2 has grooves 9 for accommodating the insert portions 8. The bottom surface of the support portion 3 corresponding to the second elastic element 5 has a receiving groove 10. A pad 11 is located below the second elastic element 5. The second elastic element 5 and the pad 11 are both located within the receiving groove 10. Corresponding positioning holes 12 are provided on the support portion 3, the second elastic element 5, and the pad 11. The positioning holes 12 on the second elastic element 5 are elongated. The width of the insert portion 8 is smaller than the width of the center of the second elastic element 5. Through the design of the above structure, the elastic element... The inserts 8 at both ends of the second element 5 can be used to enter the slots at the bottom of the deep hole plate. The arc-shaped design enhances the cushioning effect when the element 5 wobbles left and right. The inserts 8 also enhance the fixation effect on the other two sides of the bottom of the deep hole plate. The presence of the receiving groove 10 and the pad 11 is to ensure that the bottom surface of the turntable body 1 is as flat as possible. Secondly, the elongated positioning hole 12 can be used to adjust the position of the second element 5 left and right, thereby controlling the position of the inserts 8 to meet the needs of actual conditions. The width is set so that the inserts 8 can deform more easily than the second element 5, so as to satisfy the effect of the inserts 8 deforming and entering the slots at the bottom of the deep hole plate.

[0026] refer to Figures 1 to 4 As shown above, the structure allows the deep hole plate to be quickly installed on the turntable body 1. The snap-fit ​​mechanism simultaneously limits the four sides of the bottom of the deep hole plate, ensuring a secure installation that is not easily detached and preventing displacement during high-speed rotation. Furthermore, since both elastic element 4 and elastic element 5 are designed to be detachable, they can be adjusted or replaced according to actual needs to adapt to different requirements.

[0027] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions that fall within the concept of the present utility model are within the protection scope of the present utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present utility model should also be considered within the protection scope of the present utility model.
