Description

Technical Field

[0001] The utility model specifically relates to a rapid RNA purification kit and belongs to the technical field of RNA purification kits. Background Art

[0002] It is used for RNA extraction from various plants, animals, and microorganisms. There is an instruction manual in each kit. The experimenter only needs to follow the steps in the manual. No other reagents need to be prepared during use. It is very convenient and suitable for rapid RNA extraction. Existing RNA purification kits have several rows of circular grooves to place test tubes that can detect RNA. At this time, since the circular grooves of the RNA purification kit rely on the circular grooves to limit the test tubes to clamp the test tubes, when the RNA purification kit is transported, if the test tubes are not fixed stably, the outer wall of the test tubes may be accidentally damaged due to the shaking of the box body. At the same time, when the box body is at risk of falling due to an accident, the shock absorption effect of the existing device itself is weak.

[0003] In view of this, the present utility model is proposed. Utility Model Content

An annular airbag groove is provided at the middle position of the inner wall of the clamping circular hole 4 along the axial direction, and the annular clamping airbag 5 is arranged in the annular airbag groove. The inner circle diameter of the annular clamping airbag 5 is the same as the diameter of the clamping circular hole 4. Both sides of the upper surface of the clamping base 3 are provided with inflation grooves, and the airbag inflation component 6 includes an air push plate 60 1. The push plate 601 is slidably installed in the inflation groove, and sliding blocks 602 are arranged at both ends and one side of the inner wall of the inflation groove. Sliding grooves are opened at both ends and one side of the outer wall of the push plate 601. The sliding blocks 602 and the sliding grooves are slidably engaged with each other. A push rod 603 is fixedly installed at the middle position of the upper surface of the push plate 601. The upper surfaces of both ends of the push plate 601 are inlaid with air intake check valves 604. The air intake check valve 604 is connected to the inflation groove. One side of the inflation groove An air hole is provided on the inner wall of the side, and an air pipe 605 is provided in the air hole. One end of the air pipe 605 is connected to the annular clamping airbag 5, and the other end of the air pipe 605 is provided with an air blowing check valve 606. The air blowing check valve 606 is evenly arranged on the inner wall of one side of the inflation groove, so that the staff can compress the space in the inflation groove by pushing the air pushing plate 601.

When the push plate 601 slides downward, the outer wall of the push plate 601 and the inner wall of the inflation groove are sealed and fitted with each other. At the same time, when the push plate 601 is pulled up, gas can be introduced into the inflation groove through the air inlet check valve 604, and the air blowing check valve 606 is in a closed state at this time. When the push plate 601 moves downward in the inflation groove, the air inlet check valve 604 is closed and the air blowing check valve 606 is opened.

[0025] When the utility model is in use, the staff first puts the test tube into the clamping circular hole 4, and then the staff presses the pushing rod 603 by hand. At this time, the pushing rod 603 drives the pushing plate 601 to move along the inner wall of the inflation groove. At this time, the space in the inflation groove is compressed, and the gas in the inflation groove enters the annular clamping airbag 5 through the blowing one-way valve 606, thereby completing the clamping and protection function of the annular clamping airbag 5 on the test tube. At the same time, when the multi-specification test tube clamping reagent box 1 falls accidentally, the spring telescopic rod 702 is squeezed, thereby providing spring support force to the shock-absorbing rubber block 701, thereby achieving the effect of shock-absorbing the device, and the practicality is strong.
