Description

Technical Field

[0001] The utility model relates to the technical field of microbial nucleic acid detection, in particular to a placement rack for highly pathogenic microbial nucleic acid detection. Background Art

[0002] Microorganisms include: bacteria, viruses, fungi, as well as some small protozoa, microscopic algae and other large biological groups. They are tiny and closely related to humans. They cover many types of beneficial and harmful species and are widely involved in many fields such as food, medicine, industry and agriculture, and environmental protection. Some microorganisms can be seen with the naked eye, such as mushrooms and Ganoderma lucidum, which belong to fungi. There are also microorganisms that are a kind of "non-cellular organisms" composed of a few components such as nucleic acids and proteins, but their survival must rely on living cells. When conducting nucleic acid testing on microorganisms, the test liquid containing the microorganisms and the test reagent need to be added to the test tube, and then the test tube is placed on the placement rack to wait for the test results. Because the existing placement rack for microbial nucleic acid testing can only place test tubes and cannot provide the test tubes with a cyclic swinging effect, the detection time is relatively long.

[0003] Patent No. 202021323057.2 discloses a placement rack for microbial nucleic acid detection, including a placement base of a rectangular structure, the interior of the placement base is set as a hollow structure, and a first circular mounting through hole is opened on the left inner wall and the right inner wall of the placement base, and the same circular rotating shaft is rotatably installed inside the two first circular mounting through holes, and the left and right ends of the circular rotating shaft extend to the outside of the placement base, and a bracket vertical side plate is welded, and the side where the two bracket vertical side plates are close to each other is bonded and fixed with the same bracket bottom support plate located above the placement base, and the side where the two bracket vertical side plates are close to each other is also bonded and fixed with the same bracket top mounting plate located above the bracket bottom support plate. On the basis of the original, the utility model adds the function of cyclic swinging, which is conducive to shortening the detection time of the liquid to be detected in the test tube, and brings great convenience to the work of the detection personnel.

[0004] The above-mentioned placement rack has the following disadvantages: multiple test tubes swing synchronously and stop synchronously, which causes other test tubes to be affected when loading and removing the test tubes. Utility Model Content

[0018] A protective sleeve 10 is embedded in the inner wall of the clamping sleeve 5 , and the protective sleeve 10 is made of sponge material.

[0019] The connecting assembly is composed of an electric telescopic rod 11 and an arc plate 12 arranged at the end of the electric telescopic rod 11. The electric telescopic rod 11 is fixedly connected to the movable plate 9. The arc plate 12 is located on the outside of the test tube 2 as a whole, and a sponge pad 13 is provided on the inner wall of the arc plate 12.

[0020] A control box is disposed inside the base 1 , and the control box is connected to a display screen, control buttons, and an electric telescopic rod 11 on the side of the base 1 through wires.

[0021] The clamping sleeve 5 and the electric telescopic rod 11 are both provided in plurality and correspond to each other one by one.

[0022] The lower surface of the base 1 is further provided with a supporting foot 14 , and the lower end of the supporting foot 14 is provided with an anti-slip pad.

[0023] When the device is used, the lower end of the test tube 2 containing the liquid to be detected and the detection reagent is passed through the clamping sleeve 5, and the lower end of the test tube 2 is placed in the arc groove of the arc plate 12. At this time, the driving motor is controlled by the control button to work, and the reciprocating screw rod 6 is driven by the driving motor to rotate. Under the joint action of the guide rod 7, the movable plate 9, the electric telescopic rod 11, and the arc plate 12 move synchronously.

[0024] In the above process, when multiple test tubes 2 need to be loaded, the multiple electric telescopic rods 11 are controlled to be in a retracted state through the control button, and then when the movable plate 9 drives the electric telescopic rod 11 to move, the arc plate 12 will never move to the bottom of the clamping sleeve 5. At this time, the test liquid and the detection reagent are loaded into the test tube 2, and then the test tube 2 is inserted from the upper end of the clamping sleeve 5. After the insertion is completed, the corresponding electric telescopic rod 11 is extended by controlling the control button.

[0025] When a test result appears in one of the multiple test tubes 2, the corresponding electric telescopic rod 11 is controlled to retract by the control button. At this time, the test tube 2 stops swinging and the clamping sleeve 5 is rotated outward to take out the test tube 2. The other test tubes 2 are still in a cyclic swinging state.
