DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-Figure 7 as well as Figure 8-Figure 12 The present invention provides a technical solution: an intelligent protein centrifuge, comprising a main body 1, a rotor 2 movably installed in the main body 1, a plurality of placement holes 3 are provided in the rotor 2, and a cover 4 movably installed on the rotor 2, a piston 5 movably arranged in the placement hole 3, the piston 5 is used to carry a test tube, and an adaptive balancing mechanism 6 is arranged inside the rotor 2, which can automatically balance according to the weight of the test tube in the placement hole 3.

[0034] A cavity is provided in the rotor 2, and the cavity is filled with a medium. In the present embodiment, the medium is water but is not limited thereto, and may also be other solutions with the same density as the material to be centrifuged in the test tube. A flow channel 9 connected to the cavity is provided at the bottom of the placement hole 3, and the adaptive balancing mechanism 6 includes a connecting valve 7 arranged in the flow channel 9, and a moving part 8 capable of controlling the conduction and closing of the connecting valve 7 is provided on the side wall of the placement hole 3.

[0035] A side groove 81 is provided on one side of the placement hole 3, and the moving member 8 includes a moving rod 82 slidably arranged in the side groove 81. An end of the moving rod 82 located outside the side groove 81 is provided with an inclined surface, and the other end of the moving rod 82 is fixedly connected to a reset spring 83. When the test tube is placed in the placement hole 3, the test tube will squeeze the moving rod 82 to move it into the side groove 81. A connecting channel 84 is also provided in the rotating head 2. The two ends of the connecting channel 84 are respectively connected to the side groove 81 and the connecting valve 7, and a transmission rod 85 is slidably arranged on the top of the connecting channel 84. The top of the transmission rod 85 is provided with an inclined surface, and the connecting channel 84 is filled with water. When the moving rod 82 moves toward the side groove 81, it will squeeze the transmission rod 85 to make it move. When the transmission rod 85 moves, it will squeeze the water in the connecting channel 84, and then squeeze the water into the connecting valve 7.

[0036] The connecting valve 7 includes a fixed ring 71 fixedly arranged in the flow channel 9, a movable plug 72 is movably arranged on one side of the fixed ring 71, a support rod 73 is fixedly arranged on the movable plug 72, a sliding hole 74 is opened in the fixed ring 71, the support rod 73 is slidably arranged in the sliding hole 74, and the sliding hole 74 is communicated with the connecting channel 84, and a connecting spring 75 is fixedly arranged on the movable plug 72, and the two ends of the connecting spring 75 are respectively fixedly connected to the movable plug 72 and the fixed ring 71;

[0037] The transmission rod 85 squeezes the water in the connecting channel 84 into the sliding hole 74, and then the water squeezes the support rod 73 to drive the movable plug 72 to move, so that the movable plug 72 is separated from the fixing ring 71. At this time, the fixing ring 71 is in a conducting state, and the cavity is connected to the flow channel 9.

[0038] The length of the support rod 73 is greater than that of the movable plug 72 , so that the support rod 73 can drive the movable plug 72 to separate from the fixing ring 71 while preventing the support rod 73 from moving out of the sliding hole 74 .

[0039] In summary, when in use, the material to be centrifuged is placed in a test tube, and then the test tube is placed in the placement hole 3. When the test tube is placed, the test tube will squeeze the moving rod 82 to move it into the side groove 81. When the moving rod 82 moves toward the side groove 81, it will squeeze the transmission rod 85 to move it. When the transmission rod 85 moves, it will squeeze the water in the connecting channel 84, and then squeeze the water into the sliding hole 74. Then the water will squeeze the support rod 73 to drive the moving plug 72 to move, so that the moving plug 72 is separated from the fixing ring 71. At this time, the fixing ring 71 is in a conducting state, and the cavity is connected with the flow channel 9, that is, only the placement hole 3 where the test tube is placed will be connected with the cavity. Then, the test tube with a heavier weight has a larger self-weight, which will drive the piston 5 to move downward and squeeze the water at its bottom into the cavity. Since the placement hole 3 and the flow channel 9 are of the same size and specifications, and the liquid transmission pressure is also unchanged, the piston 5 at the bottom of the remaining test tubes with smaller weight will rise under the action of water pressure, that is, the weight balance between the test tubes can be achieved through the water in the cavity, and the balance is automatically performed.

[0040] The cover 4 is a hollow structure with a movable groove 12 at the bottom. A movable plate 13 is movably arranged inside the cover 4. A mounting sleeve 14 is fixedly connected to the bottom of the movable plate 13. A fixing block 15 that is plugged into the mounting sleeve 14 is fixedly arranged on the top of the rotary head 2.

[0041] A plurality of pressing plates 16 are movably provided at the bottom of the cover 4. The pressing plates 16 correspond to the placement holes 3 one by one, and elastic rubber is provided on the pressing plates 16. The elastic rubber is fixedly connected to the cover 4. A push rod 17 is also provided on the pressing plates 16. When the cover 4 is installed on the rotor 2, the top of the test tube will press against the pressing plate 16 to move it, and the pressing plate 16 will drive the push rod 17 to move and abut against the movable plate 13.

[0042] A universal shaft sleeve 18 is fixedly arranged in the sealing cover 4 , a connecting shaft 19 universally connected thereto is arranged in the universal shaft sleeve 18 , and the bottom of the connecting shaft 19 is fixedly connected to the movable plate 13 .

[0043] A screw rod 20 is installed in the inner thread of the universal shaft sleeve 18, the top thread of the screw rod 20 passes through the cover 4 and the bottom thread passes through the universal shaft sleeve 18, a slide rod 21 is movably arranged in the connecting shaft 19, a positioning rod 22 is slidably arranged in the fixed block 15, an annular groove 23 which is plugged into the positioning rod 22 is opened on the inner side of the installation sleeve 14, and an annular rubber ring is arranged in the annular groove 23, and the end of the positioning rod 22 close to the slide rod 21 is wedge-shaped.

[0044] When installing the cover 4, after all the test tubes to be centrifuged are placed according to the principle of symmetry, the cover 4 is installed on the rotor 2, and the top of the test tube will squeeze the pressure plate 16 to drive the push rod 17 to move, and the push rod 17 will squeeze the movable plate 13 when it moves. Since the test tubes are placed according to the principle of symmetry, even if multiple push rods 17 abut the movable plate 13, the movable plate 13 is still in a horizontal state at this time, that is, the installation sleeve 14 can be smoothly plugged into the fixed block 15, and then the screw rod 20 is rotated to move it downward, the screw 20 drives the sliding rod 21 to move, and the sliding rod 21 drives the positioning rod 22 to move and be plugged into the annular groove 23, so that the installation sleeve 14 and the fixed block 15 are connected, and the installation of the cover 4 is completed immediately.

[0045] On the contrary, when the test tubes are not placed according to the principle of symmetry, the push rod 17 will push the movable plate 13 to a non-horizontal state. In this case, the mounting sleeve 14 is also in a tilted state and cannot be plugged into the fixed block 15. That is, when the test tubes are not placed according to the principle of symmetry, the cover 4 cannot be installed, resulting in the centrifuge being unusable, reminding the user to place the test tubes correctly.

[0046] Example 2: Please refer to Figure 7 , which is different from the first embodiment, is that a connecting plug 10 is provided on the other side of the fixing ring 71, and a fixing spring 11 is provided between the connecting plug 10 and the fixing ring 71 to connect the two. When the centrifuge is started, that is, when the rotor 2 rotates, under the action of centrifugal force, the connecting plug 10 will move and plug into the fixing ring 71 to close the fixing ring 71, so that the cavity is no longer connected to the placement hole 3, thereby preventing the flow of water from affecting the piston 5 and the test tube due to the change in rotation speed.
