Description

Technical Field

[0001] The utility model relates to a plate frame, in particular to a general ELISA plate frame. Background Art

[0002] ELISA, that is, enzyme-linked immunosorbent assay, refers to a qualitative and quantitative detection method that binds soluble antigens or antibodies to solid-phase carriers such as polystyrene and uses the specificity of antigen-antibody binding for immune reactions.

[0003] At present, there are many existing microtiter plate specifications and different sizes. In the laboratory, several different indicators are often simultaneously subjected to ELISA experiments. In order to facilitate time memory, washing with a plate washer, and obtaining quick and accurate experimental results, generally, indicators under the same conditions are experimented at the same time. However, the pre-coated plate specifications for different indicators are not very consistent. If separate plate frames are used for experiments, even if clearly marked, it will increase the experimental difficulty. If experiments are carried out on the same plate frame, it is necessary to ensure that all the strips can be inserted into the plate frame. During the experiment, it is usually chosen to stick the edges of the strips of several indicators and the edges of the plate frame with adhesive tape to play a fixing role. However, sticking the adhesive strips is very troublesome, and after sticking, it cannot withstand the cleaning of the plate washer. The viscosity of the adhesive strips decreases in the wet state, and the strips cannot be fixed, resulting in the strips falling off in the subsequent experimental steps and even causing the experiment to be invalidated. Therefore, a general ELISA plate frame is designed to solve the above problems.

[0004] It should be noted that the above introduction of the technical background is only for the convenience of clearly and completely explaining the technical solution of the utility model and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well-known to those skilled in the art merely because these solutions are described in the background art part of the utility model. Summary of the Utility Model

[0005] To overcome the above deficiencies in the prior art, the purpose of the utility model is to provide a general ELISA plate frame.

[0006] To achieve the above purpose and other related purposes, the technical solution provided by the utility model is: a general ELISA plate frame, including a frame body, the frame body is composed of a plurality of rectangular frames combined, and the frame walls of each rectangular frame are fixedly connected to each other; the middle parts of four adjacent rectangular frames form a cross structure, and at the positions corresponding to the four corners of the cross structure, there are all inserted blocks that can resist the strips. In this solution, by using a general plate frame, strips of different sizes and specifications can be fixed together in the respective rectangular frames of the frame body, and the strips can be positioned and fastened by the inserted blocks. Compared with the existing plate frames, it can reduce the complexity of using plates in the experiment and the probability of experimental errors, halve the operation complexity, and make reading more convenient.

[0007] Furthermore, connecting holes are horizontally formed in each of the cross structures, and the connecting holes are respectively communicated with the four rectangular frames corresponding to the cross structures; the four inserts located at the same cross structure are connected into a whole through the connecting holes. In this solution, the inserts arranged at the cross structures are connected into a whole through the connecting holes, which improves the stability of the inserts at this position and facilitates the fixing of the plate strips.

[0008] Furthermore, the two side surfaces of the insert that are in contact with the inner wall of the rectangular frame are both flat and perpendicular to each other. In this solution, the two contact surfaces of the insert with the inner wall are at a right angle, which facilitates the installation of the insert at the cross structure; both contact surfaces are flat, and the installation is more stable.

[0009] Furthermore, the outer side surface of the insert is a concave arc surface, and the center line of the arc surface is vertically arranged. In this solution, the outer side surface of the insert that contacts the plate strip is set as an arc surface, which facilitates the fixing of the plate strip, and the relative space is also larger, and it can adapt to more specifications of plate strips.

[0010] Furthermore, the insert is arranged at the same height as the rectangular frame. In this solution, the contact surface between the insert and the plate strip in the height direction is ensured, and the stability between the insert and the plate strip is provided.

[0011] Furthermore, the shape of the rectangular frame is square. In this solution, the square structure is more suitable for common plate strips.

[0012] Furthermore, the widths of the two side surfaces of the insert that are in contact with the inner wall of the rectangular frame are equal and both are less than half of the width of the rectangular frame. In this solution, the insert with equal side surface widths is more stable when fixing the plate strip.

[0013] Furthermore, the number of connecting holes formed on a single cross structure is 2 to 3, and the connecting holes are vertically arranged in a uniformly distributed manner. In this solution, the vertical arrangement of the connecting holes facilitates the communication of the rectangular frames. If they are arranged horizontally, some of the connecting holes may not be able to communicate with the four rectangular frames.

[0014] Furthermore, the material of the insert is rubber. In this solution, the insert is a solid structure and is made of rubber material, which facilitates the plate strip to be inserted and embedded in the rectangular frame to maintain stability.

[0015] Furthermore, the frame body is integrally formed. In this solution, the integrally formed structure is firm and is also convenient for production.

[0016] Due to the application of the above technical solutions, the beneficial effects of the present utility model compared with the prior art are:

[0017] The ELISA universal plate frame designed by the utility model can fix strips of different sizes and specifications in each rectangular frame of the frame body, and position and fasten the strips by means of the inlay blocks against the strips. Compared with the existing plate frames, it eliminates the trouble of using adhesive strips, is convenient for fixing the strips, will not cause the strips to fall off, can reduce the complexity of using plates in the experiment process and the probability of experimental errors, halves the operation complexity, and is more convenient for reading.
