Description

Technical Field

[0001] The utility model relates to the field of centrifugal equipment, in particular to a centrifugal equipment used for biological reagents. Background Art

[0002] The centrifuge is a device that separates materials into layers according to their density after high-speed rotation. The liquid with high density sinks to the bottom layer, and the liquid with low density floats to the upper layer, thereby separating the materials to obtain the required pure substances. Centrifugal sampling is an indispensable process for the preparation of biological reagents. Since biological reagents often have certain activity, the environmental conditions for centrifugal sampling are relatively high.

[0003] However, due to the deviation in the weight of the liquid in the multiple test tubes, the center of gravity of the device shifts after the test tubes are installed. When the centrifuge rotates, periodic vibration occurs, which reduces the centrifugal effect.

[0004] Therefore, it is necessary to provide a new centrifugal device for biological reagents to solve the above technical problems. Utility Model Content

[0008] Furthermore, a plurality of positioning slots 1 are provided at equal intervals in the circumferential direction on the edge of the centrifugal disk, and a fixing frame for fixing the biological reagent tube is installed in the positioning slot 1 in a plug-in manner.

[0009] Furthermore, a pressure spring is sleeved on the outer surface of the plurality of damping telescopic rods, and two ends of the pressure spring are fixedly connected to the fixed end of the damping telescopic rod and the top wall of the connecting frame respectively.

[0010] Furthermore, a rotatable opening and closing box cover is provided on the top of the box body.

[0011] Furthermore, the connecting frame is a triangular bracket, and the number of the damping telescopic rods is three, and the three damping telescopic rods are respectively located at the corners of the triangular bracket.

The buffer bracket is fixedly installed inside the box body 1, the centrifugal motor 2 is fixedly installed on the buffer bracket, and the output end of the centrifugal motor 2 is fixedly connected to the centrifugal disk 3;

[0026] It should be noted that a rotating cover 11 is provided on the top of the box body 1, and the cover 11 can be opened and closed by a telescopic electric cylinder to maintain the sealing of the box body 1 during the centrifugation process of the biological reagent;

[0027] refer to Figure 5 As shown, the buffer bracket includes a connecting frame 4 for fixing the centrifugal motor 2 and a plurality of damping telescopic rods 5. The bottoms of the plurality of damping telescopic rods 5 are respectively fixedly mounted on the bottom wall of the box body 1, and the tops of the plurality of damping telescopic rods 5 are fixedly connected to the edge of the connecting frame 4.

[0028] The outer surfaces of the multiple damping telescopic rods 5 are also sleeved with pressure springs 8, and the two ends of the pressure springs 8 are fixedly connected to the fixed ends of the damping telescopic rods 5 and the top wall of the connecting frame 4 respectively. On the one hand, the multiple damping telescopic rods 5 can slow down most of the vibration force of the centrifugal motor 2. On the other hand, the slight vibration of the centrifugal motor 2 can help the particles in the reagent to settle better, prevent the particles from aggregating together to form large lumps that are difficult to further separate, and improve the centrifugal effect.

[0029] Further, refer to Figure 4 As shown, the edge of the centrifugal disk 3 is provided with a plurality of positioning slots 6 at equal intervals in the circumferential direction, and a fixing frame 7 for fixing the biological reagent tube is installed in the positioning slot 6 in a plug-in manner;

[0030] It should be noted that the bottom end of the fixing frame 7 is elastic;

[0031] Furthermore, the edge of the centrifugal disc 3 is circumferentially and equidistantly provided with a plurality of positioning slots 2 9 corresponding to the positions of the positioning slot 1 6 , and an elastic sheet 10 is fixedly installed inside the positioning slot 1 6 , and one end of the elastic sheet 10 is abutted against the elastic end of the fixing frame 7 , and the elastic end of the fixing frame 7 is squeezed by the elastic sheet 10 so that it is not easy to separate from the positioning slot 1 6 , on the one hand, the fixing effect of the fixing frame 7 is enhanced, and on the other hand, a finger can pass through the positioning slot 2 9 to press the elastic sheet 10 away from the elastic end of the fixing frame 7 , thereby facilitating the disassembly and assembly of the fixing frame 7 .

[0032] In a specific embodiment, the connecting frame 4 is a triangular bracket, and the number of the damping telescopic rods 5 is three. The three damping telescopic rods 5 are respectively located at the corners of the triangular bracket, and the triangular bracket has higher stability.

[0033] The working principle provided by the present invention is as follows: a fixing frame 7 for fixing a biological reagent tube is inserted into a positioning slot 1 6, and the elastic end of the fixing frame 7 is squeezed by the elastic sheet 10 so that it is not easy to separate from the positioning slot 1 6, and the centrifugal disk 3 is driven to rotate by starting the centrifugal motor 2, so that the biological reagent tube on the fixing frame 7 is rotated for centrifugal treatment. During the centrifugation process, a plurality of damping telescopic rods 5 can, on the one hand, reduce most of the vibration force of the centrifugal motor 2, and on the other hand, the centrifugal effect is improved by the slight shaking of the centrifugal motor 2. When disassembling, a finger passes through the positioning slot 2 9 to press the elastic sheet 10 to make it away from the elastic end of the fixing frame 7, so as to facilitate the disassembly and assembly of the fixing frame 7 and the biological reagent tube.
