[0002] Centrifugal purification equipment such as high-speed centrifuges are suitable for the rapid separation of trace elements. High-speed centrifuges are often used in scientific research laboratories. They are mainly used for material separation and purification. They use the high-speed rotation of the turntable to generate a strong centrifugal force to separate the various components of some particles in the solution and purify the liquid. High-speed centrifuges are used when purifying silicone oil.

[0003] In the prior art, the existing centrifugal purification equipment has a poor fastening effect between the cover and the body when in use, has certain safety hazards when rotating at high speed, and is not convenient for fixing the connection between the cover and the body, resulting in poor use effect.

[0008] Furthermore, the connecting column matches the limiting groove and the guide groove respectively, and when the lower end surface of the positioning column is in contact with the lower side of the inner wall of the avoidance groove, the axis center of the stop column coincides with the axis center of the stop hole.

[0009] Furthermore, a limiting ring is arranged on the top of the machine body, and when the lower end surface of the machine cover is in contact with the upper end surface of the limiting ring, the lower end surface of the positioning column is in contact with the lower side of the inner wall of the avoidance groove.

[0010] Furthermore, mounting bolts are provided between the mounting seat and the side wall of the machine body.

The sliding of the connecting column 15 drives the stop column 12 to be inserted into the stop hole 51 of the side wall of the positioning column 5 along the through hole 11, thereby locking the positioning column 5 to prevent it from moving upward, thereby preventing the machine cover 4 from rotating upward, improving the stability of the connection between the machine cover 4 and the body 1, avoiding looseness of the connection, enhancing the fastening effect of the connection, and facilitating the connection and fixing operation between the machine cover 4 and the body 1. Finally, the connecting column 15 is placed in the limiting groove 13 close to the side of the body 1, and the stop column 12 is limited to avoid the stop column 12 from being separated from the stop hole 51, thereby further improving the stability of the connection and fixing between the machine cover 4 and the body 1.

[0026] Reference Figure 1 and Figure 2 The connecting column 15 matches the limiting groove 13 and the guide groove 14 respectively. When the lower end face of the positioning column 5 is in contact with the lower side of the inner wall of the avoidance groove 8, the axis of the stop column 12 coincides with the axis of the stop hole 51. This design facilitates the connection and fixing operation between the stop column 12 and the stop hole 51, thereby facilitating the use of the stop column 12 to lock and fix the positioning column 5 to prevent the machine cover 4 from being separated from the machine body 1. A limiting ring 2 is provided on the top of the machine body 1. When the lower end face of the machine cover 4 is in contact with the upper end face of the limiting ring 2, the lower end face of the positioning column 5 is in contact with the lower side of the inner wall of the avoidance groove 8, thereby improving the rationality of the design.

[0027] Reference Figure 2 A mounting bolt 10 is provided between the mounting seat 9 and the side wall of the body 1. This design improves the stability of the connection.

[0028] Reference Figure 1The rotating assembly 7 includes a pair of U-shaped seats 73 symmetrically arranged on the top of the body 1, a rotating block 71 connected to the side wall of the body 1 is arranged inside the U-shaped groove of the U-shaped seat 73, and a rotating shaft 72 penetrating the rotating block 71 is arranged inside the U-shaped seat 73. This design applies force to the machine cover 4 so that the rotating block 71 at the bottom of the machine cover 4 rotates around the U-shaped seat 73 under the action of the rotating shaft 72, thereby improving the stability of the rotation of the machine cover 4.

[0029] Reference Figure 3 and Figure 5 The side wall of the machine body 1 is provided with a baffle 6 for limiting the machine cover 4 in a vertical state. The baffle 6 is L-shaped, and a fixing bolt 61 is provided between the baffle 6 and the machine body 1. This design facilitates the limiting operation of the machine cover 4 by using the baffle 6, and facilitates the subsequent application of force to the machine cover 4 to connect and fix it to the machine body 1.

[0030] Reference Figure 3 and Figure 4 A first magnet 16 is provided on one side of the baffle 6 close to the machine cover 4, and a second magnet 17 is provided on one side of the machine cover 4 close to the baffle 6. The first magnet 16 and the second magnet 17 are connected by magnetic attraction. This design improves the stability of the connection between the baffle 6 and the machine cover 4 by using the magnetic adsorption connection between the first magnet 16 and the second magnet 17, thereby improving the stability of the limit of the machine cover 4, and preventing the cover 4 from separating from the baffle 6 when placing the centrifuge tube, affecting the placement of the centrifuge tube.

[0031] Reference Figure 1-Figure 5 As an embodiment of the utility model: when it is necessary to connect and fix the cover 4 to the body 1, the staff applies force to the cover 4 so that the cover 4 drives the rotating block 71 to rotate around the U-shaped seat 73 under the action of the rotating shaft 72, and the cover 4 rotates to drive the bottom of the stop column 12 to fit with the lower side of the inner wall of the avoidance groove 8, and then applies force to the connecting column 15 to make the connecting column 15 slide inside the guide groove 14, and the sliding of the connecting column 15 drives the stop column 12 to penetrate the side wall of the body 1 along the through hole 11 to the part between the limit groove 13 and insert into the side wall of the positioning column 5 The stop hole 51 is inside the positioning column 5, thereby locking the positioning column 5 to prevent it from moving upward, thereby preventing the machine cover 4 from rotating upward, improving the stability of the connection between the machine cover 4 and the machine body 1, preventing the connection from loosening, and enhancing the fastening effect of the connection, which is convenient for connecting and fixing the machine cover 4 to the machine body 1. Finally, the connecting column 15 is placed inside the limiting groove 13 close to the side of the machine body 1, and the stop column 12 is limited to prevent the stop column 12 from escaping from the stop hole 51, thereby further improving the stability of the connection between the machine cover 4 and the machine body 1.

[0032] When it is necessary to open the machine cover 4, force is applied to the connecting column 15 to make it disengage from the limiting groove 13 close to the side of the machine body 1 and slide along the guide groove 14, so that the stop column 12 is disengaged from the stop hole 51 of the positioning column 5, thereby losing the fixation of the positioning column 5, and then force is applied to the machine cover 4, so that the machine cover 4 drives the rotating block 71 to rotate around the U-shaped seat 73 under the action of the rotating shaft 72, so that the positioning column 5 is disengaged from the avoidance groove 8, and when the machine cover 4 is in a vertical state, the baffle 6 is fitted with the machine cover 4, and the machine cover 4 is prevented from being separated from the baffle 6 under the adsorption action of the first magnet 16 and the second magnet 17, thereby facilitating the placement of the centrifuge tube inside the placement hole 31, thereby improving the practicality of the utility model.
