Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to an ELISA plate. Background Art

[0002] ELISA plates are safe, reliable and effective carriers in ELISA, and play an important role in the adsorption of antigens and antibodies;

[0003] At present, the common ELISA plate rack is a grid-like slot grid separated by mutually perpendicular horizontal and vertical bars in an outer frame. The slot grid is made of hard material. The fixation of the slats and the plate rack mainly depends on the cooperation between the slot grid and the slats, and the protrusions provided on the ends of the slats and the edge of the plate rack for clamping. This setting has the following disadvantages. First, the tightness between the slats and the plate rack will decrease with the repeated disassembly of the plate rack and the slats, and the slats may be damaged during the disassembly process; second, the existing detachable slats are divided into 8-hole strips and 12-hole strips, and the existing ELISA plate rack usually corresponds to a single type of strips, which indirectly increases the cost of use; third, the ELISA plate is often sold after being pre-coated, and during the coating process, the coating liquid may overflow and remain in the corners and gaps of the ELISA plate. Although the protrusion structure of the traditional ELISA plate rack can help the slats and the plate rack to fit tightly, there is a risk of liquid residue during the production process, and then the ELISA plate is contaminated.

[0004] In view of this, an ELISA plate that can solve the above problems is urgently needed. Utility Model Content

[0005] The purpose of the utility model is to provide an ELISA plate which solves the above problems.

[0006] In order to achieve the above object, the utility model adopts the following technical solution: an ELISA plate, comprising:

[0007] The plate frame and the slot grid, the plate frame is rectangular, the slot grid is located inside the plate frame, and is a grid-shaped placement cavity formed by multiple mutually perpendicular transverse ribs and longitudinal ribs, wherein the longitudinal ribs are provided with multiple broken notches, and the slot grid is provided with matching plate strips.

[0008] Preferably, the transverse ribs and the longitudinal ribs are made of elastic material.

[0009] Preferably, 8 placement cavities are arranged transversely and 12 are arranged longitudinally.

[0010] Preferably, the top wall of the rack is stepped, and letter markings and number markings are provided on the top wall of the rack.

[0011] Preferably, the four corners of the plate frame are provided with protruding blocks fixedly connected thereto;

[0012] Preferably, a strip-shaped protrusion is integrally connected to the lower end of at least one side of the cavity wall of the placement cavity.

[0013] Preferably, at least two clamping plates integrally connected to the outer side wall of the slot grid are provided, and a plurality of through holes are provided on the clamping plates.

[0014] Preferably, the panel frame includes a panel frame seat and at least two groups of buckle strips, the panel frame seat is provided with fixing holes matching the penetration holes, and the buckle strips are provided with buckle nails matching the penetration holes and the fixing holes.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The slots are formed by using transverse and longitudinal ribs made of elastic material and by providing broken notches on the longitudinal ribs. When the slats are loaded into the slots, the broken longitudinal ribs are squeezed by the outer wall of the cup body of the slats. The elastic deformation of the ribs at this location increases the interference fit of the raised structure, thereby achieving the purpose of fixing the slats. The use of the raised structure on the edge of the traditional plate frame is eliminated, and the risk of liquid residue during the coating process is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Embodiment 1

[0024] Please refer to the attached Figure 1-3, an ELISA plate, comprising:

[0025] A plate frame 1 and a slot 2, wherein the plate frame 1 is rectangular, and the slot 2 is located inside the plate frame 1, and is composed of a grid-shaped placement cavity 22 formed by a plurality of mutually perpendicular transverse ribs 20 and longitudinal ribs 21, wherein the longitudinal ribs 21 are provided with a plurality of fracture notches 210, and the slot 2 is provided with a plate slat 3 matching therewith;

[0026] The slot 2 of the plate frame 1 still adopts the arrangement of the grid-like placement cavity 22 formed by the transverse ribs 20 and the longitudinal ribs 21, and a plurality of fracture notches 210 are arranged on the longitudinal ribs 21. In the process of placing the slats 3 into the slot 2, the outer wall of the cup body of the slats 3 squeezes the longitudinal ribs 21 at the fracture notches 210, and causes the longitudinal ribs 21 to deform, thereby achieving the purpose of fixing the slats 3. It should be noted that in the present invention, the fracture notches 210 are arranged in a longitudinal spacing manner, that is, a group of intact longitudinal ribs 21 are spaced between two groups of longitudinal ribs 21 with fracture notches 210, but it does not mean that the fracture notches 210 cannot be arranged in other ways. For example, the fracture notches 210 are arranged on the transverse ribs 20 or the fracture notches 210 are arranged in an alternating manner on the transverse ribs 20 or the longitudinal ribs 21, which can also achieve the purpose of fixing the slats 3.

[0027] Specifically, the transverse ribs 20 and the longitudinal ribs 21 are made of elastic material; considering that the slats 3 and the slots 2 are mainly fixed by deforming the longitudinal ribs 21 at the broken notches 210 squeezed by the cup body of the slats 3, the transverse ribs 21 and the longitudinal ribs 21 need to have a certain degree of elasticity.

[0028] Specifically, the placement cavities 22 are provided with 8 in the transverse direction and 12 in the longitudinal direction.

[0029] Specifically, the top wall of the plate rack 1 is stepped, and letter markings 11 and number markings 12 are provided on the top wall of the plate rack 1; considering that the existing commonly used slats 3 have 8 holes and 12 holes, the placement cavity 22 also adopts a setting of 8 horizontally and 12 vertically, and letter markings 11 and number markings 12 are set at the same time for fast counting. In order to achieve the purpose that a single plate rack 1 and slot 2 can simultaneously adapt to 8-hole and 12-hole slats 3, the top wall of the plate rack 1 is stepped to assist in fixing the two ends of the placement slats 3.

[0030] Specifically, the four corners of the plate frame 1 are provided with protruding blocks 13 fixedly connected thereto; in order to further assist the fixation of the slats 3, the protruding blocks 13 are provided at the four corners of the plate frame 1. When all the slots 2 are used, the protruding blocks 13 will play an auxiliary fixing role.

[0031] Specifically, the lower end of the cavity wall on at least one side of the placement cavity 22 is provided with a strip protrusion 220 integrally connected thereto. In order to further utilize the extrusion force generated by the cup body of the slat 3 and the groove 2, the strip protrusion 220 is arranged in the placement cavity 22. When the cup body squeezes the longitudinal ribs 21 at the broken notch 210, the strip protrusion 220 is also squeezed. Through the reverse elastic force of the strip protrusion 220 and the longitudinal ribs 21, an effective interference fit can be provided, thereby further strengthening the fixation of the cup body and the slat 3.

[0032] Embodiment 2

[0033] Please refer to the attached Figure 4

[0034] Specifically, at least two clamping plates 23 integrally connected thereto are disposed on the outer side wall of the slot 2 , and a plurality of through holes 230 are disposed on the clamping plates 23 .

[0035] Specifically, the panel frame 1 includes a panel frame seat 14 and at least two groups of buckle strips 15 . The panel frame seat 14 is provided with fixing holes 140 matching the penetration holes 230 . The buckle strips 15 are provided with buckle nails 150 matching the penetration holes 230 and the fixing holes 140 .

[0036] In practical applications, there are three colors of ELISA plates. The first is a transparent plate, which is mainly suitable for detection of ultraviolet and visible light wavelengths. The second is white, which is used for weaker light detection and is often used for general chemiluminescence. The third is black, which has its own light absorption, so its signal is much lower than that of the white plate, so it is generally used for stronger light, such as fluorescence.

[0037] In order to expand the application scope of the ELISA plate, a detachable plate rack seat 14 and buckle strip 15 are used. The buckle pin 150 provided on the buckle strip is passed through the penetration hole 230 and then clamped in the fixing hole 140. The advantage of this method is that the slot grid 2 of the corresponding color can be quickly replaced as needed. At the same time, after it is installed, the buckle pin 150 and the fixing hole 140 are in a hidden state, which is not easy to cause the coating liquid to remain. When cleaning is required, the slot grid 2 and the plate rack 1 can be disassembled and then cleaned. This method is not easy to cause the coating liquid to remain.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
