Abstract
Description
Technical Field
[0001] This utility model relates to the field of enzyme-linked immunosorbent assay (ELISA) plate technology, specifically an ELISA plate that can prevent spillage. Background Technology
[0002] ELISA plates are essential experimental tools in enzyme-linked immunosorbent assays (ELISA). They mainly serve as solid-phase carriers and play a crucial role in immunological reactions. They are involved in determining the purity, concentration, and ratio of antigens, antibodies, and labeled antibodies or antigens. However, the edges of the wells in existing ELISA plates are flush with the plate body. If the ELISA plate is tilted or the testing table vibrates during the detection process, the sample to be tested may spill out, which can easily be mixed with other samples and cause cross-contamination. Therefore, it is necessary to implement spill prevention measures for ELISA plates.
[0003] A Chinese patent discloses an enzyme-linked immunosorbent assay (ELISA) plate that prevents spillage (authorization announcement number CN220773074U). This patented technology rotates the cover plate around the pivot point, positioning the cover plate directly above the placement slot. This allows for sealing via a sealing ring. The plate also features an observation port and a transparent lens for easy observation of the interior of the placement slot, preventing spillage of the sample and avoidance of cross-contamination with other samples.
[0004] However, most existing ELISA plates prevent spillage by installing a cover on the outside of the placement compartment. This cover requires separate installation, resulting in slow installation efficiency and affecting the usability of the ELISA plate. As in the aforementioned comparative document, which uses a separate cover installation method to prevent spillage, in practical applications, the installation efficiency is slow, affecting the protection against spillage of the test samples. Therefore, those skilled in the art provide an spill-proof ELISA plate to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to provide an enzyme-linked immunosorbent assay (ELISA) plate that can prevent spillage, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An anti-overflow ELISA plate includes an ELISA plate body and a placement groove formed on the upper surface of the ELISA plate body. An installation groove is formed on one side of the ELISA plate body. A sliding plate is slidably installed inside the installation groove. A first connecting plate is fixed to the upper surface of the sliding plate. An installation plate is connected to the upper surface of the first connecting plate. A fixing seat is installed on the upper surface of the installation plate. A fixing groove is formed inside the fixing seat. Springs are symmetrically arranged inside the fixing groove. A lifting seat is formed through the upper surface of the fixing seat. Lifting seats are symmetrically arranged on both sides of the lifting seat. An anti-overflow cylinder is provided above the placement groove on the lower surface of the lifting seat. A sealing ring is provided at the lower end of the anti-overflow cylinder. A handle is also installed on the upper surface of the lifting seat.
[0008] As a further improvement of this utility model: the first connecting plate and the sliding plate are arranged in a "T" shape, and the length of the mounting plate is longer than the length of the sliding plate.
[0009] As a further improvement of this utility model: a positioning pin is installed on the inner side of the mounting groove, and a positioning hole is opened on the rear surface of the sliding plate to engage with the positioning pin.
[0010] As a further improvement of this utility model: the radius of the anti-overflow cylinder is larger than the radius of the placement groove, and the lower end of the sealing ring is in contact with the upper surface of the enzyme-labeled plate body.
[0011] As a further embodiment of this utility model: bolts are symmetrically arranged on the upper surface of the fixing base, and mounting holes are opened on the upper surface of the mounting plate. The ends of the bolts are embedded in the mounting holes and threadedly connected to the mounting holes.
[0012] As a further embodiment of this utility model: the lower end of the spring is fixed to the lower inner surface of the fixing groove, and the upper end of the spring is fixed to the lower surface of the lifting seat.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the setting of an installation groove, a positioning pin, a sliding plate, a first connecting plate and an installation plate, allows the sliding plate and the first connecting plate to slide inside the installation groove, and the installation plate can be installed by embedding the positioning pin into the installation hole. In this way, the anti-overflow cylinder penetrating the lower surface of the second connecting plate can be quickly installed, so as to facilitate the subsequent anti-overflow treatment of the enzyme labeling plate body.
[0015] 2. This utility model, through the arrangement of a lifting seat, handle, second connecting plate, anti-overflow cylinder, sealing ring, and spring, utilizes the pulling of the handle to deform the spring. After the mounting plate is installed, releasing the handle allows the spring to return to its original deformation, thereby placing the anti-overflow cylinder outside the placement slot and sealing it with the sealing ring. This achieves anti-overflow treatment for the ELISA plate body. The structure is simple and can simultaneously prevent overflow in placement slots on the upper surface of multiple ELISA plate bodies, making it highly practical. Attached Figure Description

[0027] Example 1:
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment proposes an ELISA plate that prevents spillage, including an ELISA plate body 1 and a placement groove 11 formed on the upper surface of the ELISA plate body 1. An installation groove 12 is formed on one side of the ELISA plate body 1. A sliding plate 21 is slidably installed inside the installation groove 12. A first connecting plate 211 is fixed to the upper surface of the sliding plate 21. An installation plate 2 is connected to the upper surface of the first connecting plate 211. A fixing seat 22 is installed on the upper surface of the installation plate 2. A fixing groove 23 is formed inside the fixing groove 23. Springs 34 are symmetrically arranged inside the fixing groove 23. A lifting seat 3 is provided through the upper surface of the fixed seat 22. Lifting seats 3 are symmetrically arranged on both sides of the lifting seat 3. An anti-overflow cylinder 33 is provided on the lower surface of the lifting seat 3 above the placement slot 11. A sealing ring 331 is provided at the lower end of the anti-overflow cylinder 33. A handle 31 is also installed on the upper surface of the lifting seat 3. This arrangement allows the sliding plate 21 to slide inside the installation slot 12, which facilitates the placement of the second connecting plate 32 above the enzyme label plate body 1. The anti-overflow cylinder 33 can quickly prevent the multiple placement slots 11 from overflowing, making it highly practical.
[0029] Example 2:
[0030] The solution in Example 1 will be further described below with reference to its specific working method.
[0031] like Figure 1 , Figure 2 and Figure 3As shown, in a preferred embodiment, based on the above method, the first connecting plate 211 and the sliding plate 21 are further arranged in a "T" shape. The length of the mounting plate 2 is longer than the length of the sliding plate 21. A positioning pin 13 is installed on the inner side of the mounting groove 12. A positioning hole that engages with the positioning pin 13 is opened on the rear surface of the sliding plate 21. This arrangement allows the sliding plate 21 and the first connecting plate 211 to slide inside the mounting groove 12, so that the mounting plate 2 can be installed on the upper surface of the enzyme labeling plate body 1. The stability of the mounting plate 2 can be ensured by embedding the positioning pin 13 into the positioning hole.
[0032] like Figure 1 and Figure 4 As shown, in a preferred embodiment, based on the above method, the radius of the anti-overflow cylinder 33 is larger than the radius of the placement groove 11, and the lower end of the sealing ring 331 contacts the upper surface of the enzyme-labeled plate body 1. This setting can prevent the test sample inside the placement groove 11 from overflowing by using the anti-overflow cylinder 33, and can improve its sealing performance by using the sealing ring 331.
[0033] like Figure 3 As shown, in a preferred embodiment, based on the above method, the upper surface of the fixing base 22 is symmetrically provided with bolts, and the upper surface of the mounting plate 2 is provided with mounting holes. The ends of the bolts are embedded in the mounting holes and threadedly connected to the mounting holes. This arrangement utilizes the threaded connection between the bolts and the mounting holes, which facilitates the installation and disassembly of the fixing base 22 and the mounting plate 2.
[0034] like Figure 5 As shown, in a preferred embodiment, based on the above method, the lower end of the spring 34 is fixed to the lower inner surface of the fixing groove 23, and the upper end of the spring 34 is fixed to the lower surface of the lifting seat 3. This arrangement allows the spring 34 to deform when the handle 31 is pulled upward. At this time, there will be a distance between the anti-overflow cylinder 33 and the placement groove 11. After the mounting plate 2 is slidably installed, the handle 31 can be released, so that the spring 34 can restore its deformation and the anti-overflow cylinder 33 can move downward to prevent the test sample inside the placement groove 11 from overflowing.
[0035] Example 3:
[0036] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.
[0037] Specifically, the spill-proof ELISA plate operates as follows: First, the test sample is placed into the placement slot 11. After placement, the handle 31 is lifted upwards, causing the spring 34 inside the fixing slot 23 to deform under tension. Then, the sliding plate 21 and the first connecting plate 211 are slidably installed inside the mounting slot 12. The positioning pin 13 on the inner side of the mounting slot 12 engages with the positioning hole on the rear surface of the sliding plate 21, thereby installing the mounting plate 2. At the same time, the spill-proof cylinder 33 is positioned above the placement slot 11. Then, the handle 31 is released. After release, the spring 34 inside the fixing slot 23 returns to its original deformation, causing the spill-proof cylinder 33 to contact the upper surface of the ELISA plate body 1 downwards, thus preventing the test sample inside the placement slot 11 from spilling out. The sealing ring 331 further enhances its sealing and spill-proof effect, making it highly practical.
[0038] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
