Technical Field

[0001] The utility model relates to the technical field of experimental equipment, in particular to a centrifuge tube oscillation fixing device. Background Art

[0002] A centrifuge tube is a small test tube, usually made of materials such as polypropylene or polyethylene. Its structure is generally cylindrical, with an open upper end and a conical lower end, which is convenient for centrifuging liquids. The volume of a centrifuge tube is generally small, usually about 1.5ml~2.0ml, and some large-caliber centrifuge tubes can reach more than 50ml. The upper part of the centrifuge tube is generally marked with a volume scale, which is convenient for accurately adding or removing the required liquid. The centrifuge tube is a small test tube commonly seen in laboratories, with functions such as centrifugation, separation and storage of liquids. It is widely used in experiments in the fields of biochemistry, medicine, etc. The oscillator is a device that places the centrifuge tube on the oscillator to achieve oscillation, and is often used in related experiments. In the prior art, since there is a flat plate above the oscillator, when in use, the centrifuge tube will tilt and fall on the flat plate during the oscillation process due to the lack of fixing measures, which is prone to uneven oscillation, collision of centrifuge tubes with each other, and leakage of liquid in the tube, etc., affecting the experimental results.

[0022] Specifically, a second screw 8 is provided inside the second mounting hole 6, and the outer surface of the second screw 8 is threadedly connected to the inner surfaces of the third mounting hole 7 and the fifth mounting hole 16. The inner surface of the first mounting hole 3 is threadedly connected to the first screw 4, and the outer surface of the first screw 4 is threadedly connected to the inner surface of the fourth mounting hole 15.

[0023] Specifically, the elastic bracket 5 is linearly arranged along the upper surface of the stainless steel plate 2 , and the rubber pad 9 is relatively disposed on the inner surface of the elastic bracket 5 .

[0025] The working principles and beneficial effects of the above embodiments.

[0026] When in use, an elastic bracket 5 applicable to centrifuge tubes of different specifications is installed on the top of the stainless steel plate 2 with a second screw 8 to fix the centrifuge tube. The elastic bracket 5 is used to clamp the inner surface of the centrifuge tube, and a rubber pad 9 is fixed with an adhesive. The elasticity of the rubber material is utilized to provide a buffer for the rubber pad 9 when the centrifuge tube is clamped, so as to avoid wear on the surface of the centrifuge tube when it is fixed by the elastic bracket 5. The entire stainless steel plate 2 is fixed to the flat plate 1 of the oscillator with a first screw 4. At the same time, the vertical portions 10 on both sides of the stainless steel plate 2 are located on both sides of the flat plate 1. After the stainless steel plate 2 is installed on the flat plate 1, the elastic arc plate 11 is squeezed and deformed, the movable strut 12 moves outward, and the support spring 14 is stretched. The elastic force generated by the deformation of the elastic arc plate 11 acts in the opposite direction on both sides of the flat plate 1, so that the stainless steel plate 2 is further fastened to the flat plate 1. When the oscillator starts running, with the cooperation of the elastic arc plate 11, the relative displacement between the stainless steel plate 2 and the flat plate 1 caused by vibration can be reduced as much as possible, thereby reducing the loosening of the first screw 4 and the second screw 8 due to long-term vibration. Through the provided support spring 14, the elastic force of the stretched support spring 14 can act in the opposite direction on the elastic arc plate 11 through the movable support rod 12, which can avoid excessive deformation of the elastic arc plate 11. The overall structure is simple, and after the centrifuge tube is fixed, the samples can be neatly arranged and mixed evenly and thoroughly.
