Description

Technical Field

[0001] The utility model relates to the technical field of 96-well plates, in particular to a combined 96-well plate. Background Art

[0002] The modular 96-well plate is a widely used experimental tool in laboratories, especially in the fields of molecular biology, cell biology, enzymology, drug development, etc. It is usually made of imported optically transparent pure polystyrene and uses a special process to achieve the best adsorption state of cells. All products are sterilized by gamma rays to ensure a sterile environment.

[0003] Upon investigation, it was found that the Chinese utility model patent with publication number CN217149202U discloses a modular 96-well plate, which has slats fixed on all sides by magnetic stickers, and the slats can be reused. In the experiment, the slats blocked the water outside the 96-well plate to prevent the cells from being contaminated. The 96-well plate with fixed slats avoided the marginal effect and improved the utilization rate of the 96-well plate; however, in some specific environments, the 96-well plates need to be combined and stacked, and the main plates cannot be fixed when stacked, which is prone to tipping over.

[0004] Therefore, the utility model provides a combined 96-well plate to solve the above problems. Utility Model Content

[0006] The utility model provides a combined 96-well plate, aiming to solve the problem that the existing 96-well plates mentioned in the background technology are inconvenient to stack and combine.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a combined 96-well plate, comprising a plate body and a plurality of evenly distributed sample wells arranged on the plate body.

[0009] In order to solve the problem of stacking 96-well plates, sockets are provided at the four corners of the plate body, slots are symmetrically provided in the sockets, support plates are slidably installed at the four corners of the plate body, a support rod is fixedly installed at one end of the support plate away from the plate body, a fixed head corresponding to the socket is fixedly installed at one end of the support rod away from the support plate, a sliding head is sleeved on the support rod, the sliding head is slidably connected to the support rod, a return spring is fixedly installed between the sliding head and the support plate, and a limiting mechanism adapted to the fixed head and the sliding head is provided in the slot;

[0010] The limiting mechanism comprises a slide bar slidably mounted in the slot, a limiting block fixedly mounted at one end of the slide bar located outside the slot, and an ejection spring fixedly mounted between the slide bar and the slot;

[0011] The four corners of the plate body are provided with guide openings corresponding to the support plate, and the plate body is symmetrically provided with a toggle mechanism adapted to the support plate. Through the coordinated use of the fixed head, the sliding head and the socket, two adjacent plate bodies are more stable when stacked to avoid tipping.

[0012] Preferably, in order to solve the problem of lifting the limit of the support plate movement, the toggle mechanism includes a guide plate slidably installed in the guide port, a support spring fixedly installed between the guide plate and the guide port, and a toggle plate fixedly installed on one end of the two guide plates on the same side away from the support plate, and one end of the guide plate located in the guide port is fixedly connected to the support plate. The toggle of the toggle plate can drive the two support plates on the same side to slide, and the support plate can be supported by the support spring so as to be installed with the socket.

[0013] Preferably, in order to solve the problem of separation of the fixed head, the sliding head and the socket, the fixed head and the sliding head are both truncated cone-shaped, and the fixed head and the sliding head have the same size. Through the design of the shape and size of the fixed head and the sliding head, they can be quickly separated from the socket so that the board body can be used alone.

[0014] Preferably, in order to solve the contact problem between the limit block and the fixed head and the sliding head, the end of the limit block away from the slide rod is set as an inclined surface adapted to the fixed head and the sliding head.

The lower plate body can be inserted into one end of the upper plate body through the supporting side plate, further reinforcing the stacking.

[0016] Preferably, in order to solve the problem of liquid flowing out of the sample hole, an overflow slot is provided at one end of the plate body away from the supporting side plate. When the liquid in the sample hole flows out, the overflow slot can form a barrier to reduce the liquid flowing onto the desktop.

[0017] (III) Beneficial effects
