[0002] Laboratory centrifuges work by using a high-speed rotating rotor to rotate the sample, thus separating substances with different sedimentation coefficients and buoyant densities.

[0003] A search revealed that existing technology, such as announcement number CN216727741U, discloses a temperature-controllable laboratory centrifuge, comprising a base plate, with casters at each of the four corners of the base plate, a connecting seat fixedly connected to the top of the base plate, a through groove inside the connecting seat, an air extraction component inside the through groove, a centrifuge tank connected to the top of the connecting seat, a connecting component between the centrifuge tank and the connecting seat, and a temperature regulating component on the top of the centrifuge tank. This allows for temperature regulation of the connecting seat and the inside of the centrifuge tank, and enables convenient installation and disassembly of the centrifuge tank when needed. It also effectively prevents dust from entering the centrifuge tank, heating tank, and connecting seat, thereby improving the convenience and practicality of the centrifuge during use.

[0004] In summary, existing experimental centrifuges have improved the convenience of using this centrifuge, but the bottom stability of existing experimental centrifuges is insufficient. Therefore, an experimental centrifuge that is easy to automatically balance is proposed. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a laboratory centrifuge that is easy to automatically balance, based on... Figure 1 As shown, the base 1 has a mounting groove 101 at the bottom, and a suction cup 102 is provided inside the mounting groove 101.

[0025] To further explain, an anti-slip layer 4 is adhered and fixed to the bottom of the base 1. The anti-slip properties of the bottom of the base 1 can be improved by setting the anti-slip layer 4.

[0026] One side of the suction cup 102 is connected to an air inlet pipe 103, and the end of the air inlet pipe 103 extends to the outside of the base 1. An air plug is installed inside the end of the air inlet pipe 103, and the air plug is connected to a connecting ring set on the top of the base 1 through a connecting line. The other side of the suction cup 102 is connected to a vacuum pump 105 set on the top of the base 1 through an air extraction pipe 104. When it is necessary to limit the position of the device, the device is placed on a flat surface. After placement, the vacuum pump 105 is turned on. Under the action of the vacuum pump 105, the gas inside the suction cup 102 is extracted to form a negative pressure inside. The negative pressure makes the base 1 firmly fixed in the placement position, thereby limiting the position of the device. When it is necessary to move the device, the air plug is pulled out, and air enters the suction cup 102 through the air inlet pipe 103. When the air pressure inside the suction cup 102 returns to normal, the suction cup 102 no longer adsorbs the placement surface.

[0027] according to Figure 1-4 As shown, specifically, a centrifuge box 2 is provided on the top of the base 1, and a door 201 is provided on the top of the centrifuge box 2. A door baffle that works with the door 201 is provided on the top of the inner side of the centrifuge box 2. A centrifuge balancing device 3 is rotatably provided inside the centrifuge box 2.

[0028] Specifically, a limiting baffle mechanism 5 is installed on one side of the top of the centrifuge 2 to cooperate with the door 201. The limiting baffle mechanism 5 includes a baffle 501, and one end of the baffle 501 is connected to one side of a movable plate 503 that is slidably disposed inside the mounting box 502. The mounting box 502 is installed inside a groove opened on one side of the top of the centrifuge 2. The other side of the movable plate 503 is connected to a handle 505 disposed on the outside of the mounting box 502 via a pull rod 504. The side of the movable plate 503 near the pull rod 504 is connected to the inner wall of one side of the mounting box 502 via symmetrically arranged springs 506. When it is necessary to open the door 201, the handle 505 is pulled. The handle 505 drives the movable plate 503 and the baffle 501 to move via the pull rod 504. At this time, the springs 506 are in a compressed state. When the baffle 501 is no longer directly above the door 201, the door 201 can be opened.

[0029] Specifically, the centrifugal balancing device 3 includes a drive rod 301, a stabilizing ring 3011 fixedly installed on the outside of the drive rod 301, and the stabilizing ring 3011 is rotatably connected to the support plate 3012 provided inside the centrifuge box 2. By setting the stabilizing ring 3011, the stability of the drive rod 301 during rotation can be improved. One end of the drive rod 301 is connected to the drive motor 302 provided at the bottom of the inner side of the centrifuge box 2. The drive rod 301 can drive the centrifugal disc 303 to rotate. Several sets of sliding grooves 304 are provided on the centrifugal disc 303. Sliding blocks 305 are slidably connected to the inner side of the sliding grooves 304. A weighing open cylinder 306 is installed inside the sliding block 305. A weighing sensor 3061 is installed at the bottom of the inner side of the weighing open cylinder 306. An electric telescopic rod 307 that drives the sliding block 305 to move is provided inside the sliding grooves 304.

[0030] In use, the centrifuge tube is placed in the weighing open cylinder 306. The weighing sensor 3061 at the bottom of the weighing open cylinder 306 detects the mass of the centrifuge tube and can calculate the centrifugal force of the centrifuge tube according to the centrifugal force calculation formula. Under the premise of the same centrifugal force setting, the distance between the sliding block 305 and the center of the centrifugal disk 303 is pushed and pulled by the electric telescopic rod 307 to realize the rapid adjustment of the centrifuge tube balancing.
