[0021] The present invention will now be described in detail with reference to various embodiments. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.

[0022] This utility model provides an assembled orifice plate for storing sample tubes; the assembled orifice plate includes: an orifice plate body and at least one orifice plate unit; the orifice plate unit includes: a unit body and a plurality of first sample holes disposed on the unit body; the orifice plate unit is detachably installed on the orifice plate body; when the orifice plate unit is installed on the orifice plate body, the upper end of the orifice plate unit extends from the mounting surface; the orifice plate body is also provided with at least one row of second sample holes, the depth of the second sample holes being less than the depth of the first sample holes.

[0023] The technical solution of the assembled perforated plate of this utility model will be illustrated below with reference to an embodiment.

[0024] like Figures 1 to 3 As shown, this embodiment provides an assembled orifice plate, comprising: an orifice plate body 10 and at least one orifice plate unit 20, wherein the orifice plate body 10 is used for detachable installation of the orifice plate unit 20. Thus, by providing a detachable orifice plate unit 20, the orifice positions for housing test tubes can be flexibly adjusted, allowing for the configuration of the corresponding number of orifice positions according to the number of test tubes, thereby avoiding waste of the orifice plate. Simultaneously, the orifice plate body 10 of the assembled orifice plate is reusable, further saving consumables.

[0025] To enable detachable installation of the orifice plate unit 20, the orifice plate body 10 is provided with a mounting groove 11, in which the orifice plate unit 20 can be detachably installed. Furthermore, when the orifice plate unit 20 is installed on the orifice plate body 10, its upper end extends from the mounting surface, facilitating the insertion of the test tube into the orifice plate unit 20.

[0026] Meanwhile, to prevent the perforated plate unit 20 from shaking, one of the unit body and the inner wall of the mounting groove 11 is provided with a limiting groove 111, and the other is provided with a limiting block 21 that can cooperate with the limiting groove 111. In one embodiment, the limiting block 21 is a rib provided on the outer wall of the unit body. In this case, there are two ribs, which are arranged parallel to each other on the wall surface. And the rib can cooperate with the limiting groove 111 on the inner wall of the mounting groove 11.

[0027] For the orifice plate unit 20, it includes: a unit body 22 and a plurality of first sample holes 23 disposed on the unit body 22. In order to achieve independent arrangement of each sample hole, in any orifice plate unit 20, a partition 24 is disposed between the plurality of first sample holes 23.

[0028] To accommodate test tubes of different sizes and / or specifications, the orifice plate body 10 is also provided with at least one row of second sample holes 12, the depth of which is less than the depth of the first sample holes 23. That is, by providing the first sample holes 23, it can be used to accommodate longer test tubes; while by providing the second sample holes 12, it can be used to accommodate shorter test tubes.

[0029] To facilitate the storage of the test tubes, the shapes of the first sample hole 23 and the second sample hole 12 were optimized. Specifically, the first sample hole 23 extends longitudinally, with its inner diameter gradually decreasing at the bottom, and its bottom surface is a convex conical surface. Similarly, the second sample hole 12 extends longitudinally, with its inner diameter gradually decreasing, and its bottom surface is a convex conical surface.

[0030] Furthermore, to ensure that the test tubes are neatly arranged in the assembled orifice plate, several first samples are arranged side-by-side on the unit body 22. Further, there are multiple sets of orifice plate units 20, and multiple rows of second sample holes 12. In this case, the orifice plate units 20 and the second sample holes 12 are arranged in an array. In one embodiment, an orifice plate unit 20 is disposed between any two adjacent rows of second sample holes 12.

[0031] In summary, the assembled orifice plate of this invention, by setting up detachable orifice plate units, allows for flexible adjustment of the orifice positions for storing test tubes. This enables the configuration of the corresponding number of orifice positions according to the number of test tubes, thus avoiding waste of the orifice plate. Furthermore, the orifice plate body of the assembled orifice plate is reusable, further saving on consumables.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
