Description

Technical Field

[0001] The utility model relates to the technical field of biochemical test experimental consumables, in particular to a 96-well plate with an adjustable base. Background Art

[0002] The 96-well plate, part of the dish series, is typically made of imported optically transparent pure polystyrene. It is widely used in the pre-processing of clinical mass spectrometry biological samples, primarily for high-throughput sample processing. Whether in protein precipitation, liquid-liquid extraction, or solid-phase extraction, these can all be accomplished using a 96-well plate. A traditional 96-well plate consists of 8 rows by 12 columns of wells. These wells are typically labeled with numbers or letters on the side of the first row and column to facilitate identification of each well's location during operation.

[0003] However, when using 96-well plates, they can only be placed flat. Due to the large number of wells in a 96-well plate and the lack of clear markings between the wells, it is difficult to accurately find the row and column corresponding to each well during operation. During the sample addition process, the bottom status of the eight-tube strip cannot be observed, which may cause some problems, such as repeated sample addition or missed sample addition. Once this happens, it will not only affect work efficiency, but also the experimental results. In severe cases, it may even lead to the failure of the experiment.

[0004] To this end, we propose a 96-well plate with an adjustable base to solve the above-mentioned technical problems existing in the prior art. Utility Model Content

[0007] Furthermore, the limit locking structure includes an elastic pressure piece arranged on the sliding connection end of the slider and the slide groove, and the slider is provided with a groove body for the elastic pressure piece to move up and down. The elastic pressure piece protrudes from the upper open end of the groove body in the initial state, and one end of the elastic pressure piece extends outward from the slide groove to form a pressing part. The groove edge of the slide groove is evenly provided with a plurality of limit grooves for cooperating with the elastic pressure piece. In the locked state, the elastic pressure piece is stuck in the limit groove to lock and limit the slider.

[0008] Furthermore, the elastic pressing sheet is provided at either the upper end or the lower end of the slider, or one is provided at each of the upper and lower ends of the slider.

[0009] Furthermore, the lower end of the inclined support plate is fixedly connected to the rear end of the bottom support plate.

[0032] In view of the problems existing in the prior art, the present invention provides a 96-well plate with an adjustable base. The present invention is described in detail below with reference to the accompanying drawings.

[0033] See Figure 1-Figure 5 As shown, the technical solution adopted in this specific embodiment is: Example 1

[0034] The 96-well plate according to claim 1, wherein the bottom edge of the 96-well plate body 1 is provided with a V-shaped base 1 and a 96-well plate body 2 arranged on the V-shaped base 1. The V-shaped base 1 includes a bottom support plate 11 and an inclined support plate 12, the lower end of the inclined support plate 12 is fixedly connected to the rear end of the bottom support plate 11; the front end of the 96-well plate body 1 is hinged to the front end of the inclined support plate 12, and can rotate relative to the inclined support plate 12. The left and right sides of the 96-well plate body 1 are respectively provided with an I-shaped support rod 3, the lower end of the I-shaped support rod 3 is hinged to the lower end side of the inclined support plate 12, and the upper end of the I-shaped support rod 3 is hinged to a slider 31 toward one side of the 96-well plate body 1. The side of the 96-well plate body 1 is laterally provided with a slide groove 21 that slidably cooperates with the slider 31, and the slider 31 can slide laterally in the slide groove 21 to adjust the downward tilt angle of the 96-well plate body 1. In the initial state, the 96-well plate body 1 is parallel to the bottom support plate 11, that is, the 96-well plate body 1 is placed horizontally, and the I-type support rod 3 is in a vertical state. When the sliding slider 31 approaches the front end of the 96-well plate body 1, the angle between the 96-well plate body 2 and the inclined support plate 12 gradually becomes smaller, thereby realizing the adjustment of the inclination angle of the 96-well plate body 2.

[0035] It should be specifically explained that the slider 31 is provided with a limit locking structure to limit the specific position of the slider 31 on the slide groove 21 .

[0036] Specifically, the limit locking structure includes an elastic pressure piece 311 disposed at the sliding connection end between the slider 31 and the slide groove 21. The slider 31 is provided with a groove body 312 for the elastic pressure piece 31 to move up and down. In the initial state, the elastic pressure piece 31 protrudes from the upper open end of the groove body 312, and one end of the elastic pressure piece 31 extends outward from the slide groove 21 to form a pressing portion to facilitate pressing the elastic pressure piece 31 downward. The groove edge of the slide groove 21 is evenly provided with multiple limit grooves 211 for cooperating with the elastic pressure piece 31. In the locked state, the elastic pressure piece 31 is stuck in the limit groove 211 to lock the slider 31.

[0038] Of course, the limit locking structure is not limited to the structure specifically exemplified in this application, and may also be some other locking structures commonly found in the current prior art, which the applicant will not elaborate on here.

[0039] It should be specifically explained that anti-slip pads 111 are respectively bonded and fixed to the four corners of the bottom surface of the bottom support plate 11 to improve the anti-slip ability of the bottom support plate 11 .

[0040] Example 2

[0041] This embodiment differs from Embodiment 1 in that the lower end of the inclined support plate 12 is hinged to the rear end of the bottom support plate 11 and is rotatable relative to the bottom support plate 11. An L-shaped rotating bracket 4 is provided on each left and right side of the bottom support plate 11. The L-shaped rotating bracket 4 includes a transverse support rod 41 and a longitudinal adjustment rod 42. The longitudinal adjustment rod 42 is secured to the side of the bottom support plate 11 by an adjustment bolt 43. The side of the bottom support plate 11 is provided with a screw hole 113 that threadably engages the adjustment bolt 43. The adjustment bolt 43 is threadedly connected to the longitudinal adjustment rod 42 and the bottom support plate 11 in sequence. A first tooth portion 421 is provided on the assembly surface of the longitudinal adjustment rod 42, and correspondingly, a second tooth portion 431 is provided on the assembly surface of the adjusting bolt 43. When the adjusting bolt 43 is locked, the first tooth portion 421 and the second tooth portion 431 engage and lock, so that the L-shaped rotating bracket 4 cannot flip downward; the transverse support rod 41 is provided below the inclined support plate 12, and is used to support the inclined support plate 12 after the inclined support plate 12 rotates a certain angle, thereby changing the working height of the 96-well plate body 2.

[0042] A placement groove 112 is formed on the upper surface of the bottom support plate 11 along its length. In an initial state, the transverse support rod 41 can be received and placed in the placement groove 112 .

[0043] It should be further explained that the two transverse support rods 41 of the L-shaped rotating brackets 4 are connected to form an integral body via a connecting rod 44 .

[0044] It should be specifically explained that the contact surface between the transverse support rod 41 and the inclined support plate 12 is provided with anti-slip ridges 411 , and the anti-slip ridges 411 can be made of rubber or silicone material, and the anti-slip ridges 411 can be dot-shaped ridges or strip-shaped ridges.

[0045] Example 3

[0046] The difference between this embodiment and embodiments 1 and 2 is that a counterweight 114 is embedded in the bottom center or symmetrical positions on both sides of the bottom support plate 11. By setting the counterweight 114, the weight of the V-shaped base 1 can be appropriately increased to avoid the top-heavy phenomenon of the 96-well plate body 1 after adding reagents or samples, thereby improving the placement stability.
