Description

Technical Field

[0001] The utility model relates to the technical field of extraction kits, in particular to an extraction kit for RNA extraction. Background Art

[0002] RNA extraction kits are used to extract RNA from various plants, animals, and microorganisms. Each kit includes a user manual. Simply follow the instructions. No additional reagents are required, making this kit extremely convenient and suitable for rapid RNA extraction. The extracted RNA is of high integrity and purity, making it suitable for subsequent molecular biology experiments.

[0003] The structure of the existing test kit is too simple. When the test kit is carried around, the reagent bottles in the test kit will shake violently, which will inevitably cause the reagent bottles to break, causing the samples in the reagent bottles to flow out, resulting in sample destruction and contamination of the box body by the sample.

[0004] Therefore, in order to solve the above problems, an extraction kit for RNA extraction is proposed. Utility Model Content

[0005] The utility model aims to provide an extraction kit for RNA extraction, comprising a kit body, wherein the upper rear end of the kit body and the lower rear end of a box cover are rotatably connected by a hinge, mounting blocks are respectively provided on both sides of the top of the box cover, a rotating handle is rotatably connected between the two mounting blocks, a buffer cotton block is provided at the bottom end of the interior of the kit body, a plurality of test tube slots are provided above the buffer cotton block, a fixing plate is provided above the buffer cotton block, a plurality of through holes are provided on the fixing plate, a buffer structure is respectively provided on both sides of the top end of the interior of the box cover, the bottom of the buffer structure is connected to a buffer pressure plate, and a plurality of grooves are provided below the buffer pressure plate.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0007] The utility model is provided with a second mounting block, a sliding rod, a sliding sleeve, a buffer spring, a first connecting frame, a rotating rod, and a second connecting frame. When the box cover is closed, the buffer pressure plate generates upward pressure, the rotating rod drives the sliding sleeve to slide on the sliding rod, and the two sliding sleeves approach each other, so that the buffer spring is compressed and micro-pressure is generated to prevent the extraction test tube from shaking during movement.

[0008] The utility model provides a buffer cotton block, and the extraction test tube is inserted into the test tube groove inside the buffer cotton block, so as to facilitate fixing the extraction test tube. The buffer pressure plate cooperates with the buffer cotton block, so as to facilitate buffering when collision occurs during movement.

[0009] The utility model can facilitate carrying the reagent box body by arranging a rotating handle on the box cover. BRIEF DESCRIPTION OF THE DRAWINGS
