[0031] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0032] like Figure 1 and Figure 2 As shown, the combined structure of the porous plate and the cover plate includes:

[0033] A porous plate 100 , wherein a plurality of holes 110 are formed on the upper surface of the porous plate 100 ;

[0034] At least one covering sliding assembly 200, the covering sliding assembly 200 includes a covering plate 210 and a sliding rod 220, the sliding rod 220 is located above the porous plate 100 and can move relative to the porous plate 100, the covering plate 210 is rotatably connected to the sliding rod 220.

[0035] The sliding rod 220 drives the covering plate 210 to move, and the covering plate 210 can rotate relative to the sliding rod 220, that is, the covering plate 210 can not only move but also rotate, providing a variety of covering methods for the holes 110 of the porous plate 100. Compared with the covering method of multiple sliding plates in the prior art, it is not only convenient and fast to cover, but also effectively reduces the number of covering plates, thereby reducing costs, and can effectively avoid samples from being added to the wrong rows or holes and block aerosol volatilization, avoiding cross contamination and the possibility of carrying contamination.

[0036] like Figure 1 As shown, the combined structure of the porous plate and the cover plate further includes:

[0037] The bottom surface of the multi-well plate 100 abuts against the base 300 , and both ends of the sliding rod 220 slide on the base 300 .

[0038] The size of the base 300 is slightly larger than that of the porous plate 100 so that both ends of the sliding rod 220 can slide on the base 300. The base 300 and the porous plate 100 can both be rectangular, but are not limited thereto.

[0039] The multi-well plate 100 is placed on the base 300 , with the bottom surface of the multi-well plate 100 abutting against the base 300 , and a plurality of holes 110 are provided on the top surface of the multi-well plate 100 . The holes 110 are used to place samples, and the cross-section of the holes 110 is circular.

[0040] refer to Figure 1 The porous plate 100 has 96 holes 110, which are divided into 12 columns, with each column containing 8 holes 110. The 12 columns of holes 110 can be labeled with numbers such as 1, 2, and 3, and the holes 110 in each column can be labeled with letters such as A, B, and C for identification.

[0041] As a preferred embodiment, the plurality of holes 110 are arranged in multiple columns along the length of the multi-well plate 100, with the holes 110 in each column corresponding to different colors. For example, the holes 110 in the first column are dark blue, the holes 110 in the second column are light blue, and so on. This allows for clear identification of the column number to which the sample is added, effectively avoiding the risk of adding the sample to the wrong row or hole.

[0042] Furthermore, different color stripes for differentiation can be applied to the base 300. Since the porous plate 100 is made of porous material, when the porous plate 100 is placed on the base 300, the holes 110 in different columns of the porous plate 100 correspond to different color strips.

[0043] like Figure 1 As shown, the covering sliding assembly 200 further includes:

[0044] Two pulleys 230 are connected to both ends of the sliding rod 220 , and are located on both sides of the porous plate 100 .

[0045] A bearing may be provided between the sliding rod 220 and the pulley 230 to make the sliding of the sliding rod 220 smoother and more stable. The sliding rod 220 can move along the length direction of the porous plate 100, that is, the covering plate 210 can move along the length direction of the porous plate 100.

[0046] like Figure 1 As shown, the cover plate 210 has an inner edge 211, and the center of the inner edge 211 is spherically connected to the center of the sliding rod 220. That is, the cover plate 210 can rotate 360 ​​degrees around the spherical connection position.

[0047] like Figure 1 As shown, the combined structure of the porous plate and the cover plate further includes:

[0048] The support 400 is disposed at the edge of the base 300 and is used to dock the cover plate 210 to prevent the cover plate 210 from directly contacting the upper surface of the porous plate 100 and causing contamination.

[0049] Continue to refer Figure 1 The number of the brackets 400 is four, and the four brackets 400 are respectively arranged at the four corners of the base 300.

[0050] like Figure 1 As shown, the cover plate 210 further has an outer edge 212, the outer edge 212 and the inner edge 211 are opposite, and the distance between the outer edge 212 and the inner edge 211 defines the width of the cover plate 210, and the width of the cover plate 210 is not greater than the sum of the diameters of the eight holes 110;

[0051] The cover plate 210 further has a left side 213 and a right side 214 , the left side 213 and the right side 214 are opposite to each other, and the distance between the left side 213 and the right side 214 defines the length of the cover plate 210 , and the length of the cover plate 210 is not greater than the sum of the diameters of the 12 holes 110 .

[0052] Of course, the sizes of the cover plate 210 and the porous plate 100 can be adjusted according to usage requirements.

[0053] like Figure 2 As shown, the sliding rod 220 drives the cover plate 210 to move rightward, and then the cover plate 210 rotates rightward around the sliding rod 220 until the right side of the cover plate 210 rests on the bracket 400. In this way, the cover plate 210 can cover the hole 110 on the right side of the sliding rod 220, while exposing the hole 110 of the sliding rod 220.

[0054] It should be noted that the distance between the sliding rod 220 and the porous plate 100 is small to prevent contamination caused by a large gap between the two. The length of the bracket 400 is also small. The bracket 400 can not only be used to dock the cover plate 210, but also can be used to create a gap between the cover plate 210 and the porous plate 100 so that the cover plate 210 can be flipped over by utilizing the gap.

[0055] like Figure 3 、 Figure 4 As shown, the covering plate 210 can rotate 90 degrees relative to the hinge and then flip upward or downward to cover the hole 110 located above or below.

[0056] The method for using the combined structure of the porous plate and the cover plate is as follows:

[0057] The multi-well plate 100 to be loaded with the sample to be tested is placed on the base 300 with different color stripes, so that the holes 110 in different columns of the multi-well plate 100 correspond to different color stripes.

[0058] When it is necessary to add samples on the multi-well plate 100 in columns, the cover plate 210 is converted from vertical to horizontal and placed on the bracket 400. Figure 2 The remaining holes are covered with the cover plate 210 , and the samples are added one by one to the holes 110 in each column by moving the sliding rod 220 .

[0059] When the number of available holes 110 decreases, the cover plate 210 can be rotated in the opposite direction so that the cover plate covers the holes 110 where samples have been added.

[0060] When it is necessary to add samples on the multi-well plate 100 in rows, the cover plate 210 is converted to a vertical state and rotated to become a horizontal cover plate and placed on the bracket 400. Figure 3 and Figure 4 Similarly, the holes 110 where the sample to be tested is to be added are reserved, and the remaining holes 110 are covered with the cover plate 210. Samples are added one by one by moving the sliding rod 220. When the number of empty holes 110 decreases, the cover plate 210 can be rotated in the opposite direction to cover the holes 110 where the sample has been added.

[0061] In summary, the sliding rod 220 drives the cover plate 210 to move, and the cover plate 210 can rotate relative to the sliding rod 220, that is, the cover plate 210 can not only move, but also rotate, providing a variety of covering methods for the holes 110 of the porous plate 100. Compared with the covering method of multiple sliding plates in the prior art, it is not only convenient and quick to cover, but also effectively reduces the number of cover plates, thereby reducing costs, and can effectively prevent samples from being added to the wrong rows or holes and block aerosol volatilization, avoiding cross contamination and the possibility of carryover contamination. Through the movement and rotation of the cover plate 210, a variety of covering methods can be completed, and the operation is simple. It can effectively cover the hole plates with or without samples added, perform physical isolation, effectively avoid sample splashing, and prevent cross contamination and carryover contamination to the greatest extent. By using markings and colors to distinguish the holes 110, the number of columns to which samples are added can be clearly observed, and the risk of adding samples to the wrong rows or holes can be more effectively avoided.

[0062] The embodiments described above are only used to illustrate the technical ideas and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The scope of patent application of the present invention cannot be limited by these embodiments alone. That is, any equivalent changes or modifications made according to the spirit disclosed by the present invention still fall within the patent scope of the present invention.
