[0002] A centrifuge refers to a device that uses centrifugal force technology to separate the components in a mixture of liquid and solid particles or liquid and liquid. It mainly works based on the principle that objects with different densities are immiscible. A centrifuge can also be used to remove liquid from wet solids. Currently, the centrifuges in use usually adopt automation technology, that is, the whole centrifugation process is automated without the need for shutdown and unloading, thus greatly improving productivity.

[0003] After retrieval, for example, in the utility model patent with the Chinese patent number CN219647799U, a centrifuge fixing component in a centrifugal device is disclosed. This device fixes the bottom and outer wall of the centrifuge by setting a fixed installation component, driving a protective gasket to press against the fixed bottom plate at the bottom of the centrifuge by rotating a locking screw, and at the same time, the side plate closely adheres to the outer wall of the centrifuge. However, when this device is in use, there are many operation steps. Not only is it necessary to control the electric lifting rod to drive the slot to align with the pin, which is difficult to operate, but also if the pin is forcibly inserted into the slot without complete alignment, the pin may break due to uneven force during the operation of the centrifuge, and it cannot be fixed quickly. Therefore, a centrifugal device with a quick fixing mechanism is proposed to solve the above problems. Content of the Utility Model

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , a centrifugal device with a fast fixing mechanism in this embodiment, includes a base 1, a fixed seat 2 is fixedly installed on the top of the base 1, a centrifuge body 3 is arranged inside the fixed seat 2, and a fixing mechanism 4 is arranged between the fixed seat 2 and the centrifuge body 3.

[0025] A rotating plate 401 is hinged to the front side of the fixed seat 2. An L-shaped plate 402 is fixedly installed on the left side of the fixed seat 2. An electric telescopic rod 403 is fixedly installed on the side wall of the L-shaped plate 402. A clamping block 404 is fixedly installed at the free end of the electric telescopic rod 403. A clamping groove 405 is formed on the left side wall of the rotating plate 401. A housing 406 is fixedly installed on the rear side of the rotating plate 401. A motor 407 is fixedly installed on the right inner wall of the housing 406. A bidirectional threaded rod 408 is fixedly installed at the output shaft of the motor 407. Two threaded sleeves 409 are threadedly connected to the outside of the bidirectional threaded rod 408. A hinge block 410 is fixedly installed on the rear side of the threaded sleeve 409. A connecting rod 411 is hinged to the hinge block 410. A fixing plate 412 is arranged on the rear side of the housing 406. A hinge seat 413 is fixedly installed on the front side of the fixing plate 412. When the rotating plate 401 rotates into the fixed seat 2, the clamping groove 405 is directly aligned with the opening, so that the electric telescopic rod 403 drives the clamping block 404 to be clamped into the clamping groove 405 to complete the preliminary fixation. Then, control the motor 407 to drive the bidirectional threaded rod 408 to rotate, drive the two threaded sleeves 409 to move towards each other, and drive the fixing plate 412 to approach the centrifuge body 3 to fix its side wall, which is fast and convenient for fixation.

[0026] An opening is formed on the left side of the fixed seat 2. The outer wall of the clamping block 404 is slidably connected to the opening, and the clamping block 404 moves through the opening into the clamping groove 405.

[0027] A sliding hole is formed on the rear side wall of the housing 406. One end of the connecting rod 411 away from the hinge block 410 extends to the outside of the housing 406 through the sliding hole, and the sliding hole facilitates the limitation of the threaded sleeve 409 to prevent it from rotating spirally.

[0028] Shock-absorbing pads are respectively arranged on the left, right and bottom three sides of the inner wall of the fixed seat 2. Four supporting feet are fixedly installed at the bottom of the base 1. The shock-absorbing pads can be made of rubber, springs or other materials with shock-absorbing performance to absorb and disperse vibrations.

[0029] After fixation, the human cells that need to be centrifuged can be placed into the centrifuge body 3, and then the centrifuge body 3 is started. The centrifuge body 3 rotates the sample at a high speed, so as to achieve the effect of separating the sample.

[0030] During implementation, the following steps are carried out for operation:

[0031] 1) First, place the centrifuge body 3 into the fixed seat 2 and push it inward so that the rear side wall of the centrifuge body 3 fits against the rear inner wall of the fixed seat 2;

[0032] 2) Then rotate the rotating plate 401 into the fixed seat 2, and control the electric telescopic rod 403 to drive the clamping block 404 to engage with the clamping groove 405 to complete the preliminary fixation. Control the motor 407 to drive the fixing plate 412 to approach the centrifuge body 3 to fix its side wall.

[0033] 3) Finally, drive the pressing plate 7 to move downward by rotating the threaded rotating rod 6 to strengthen the fixation of the top of the centrifuge body 3. After the fixation is completed, bolts can be used to limit the threaded rotating rod 6 to prevent the threaded rotating rod 6 from rotating during the operation of the centrifuge body 3.

[0034] In summary, for the centrifugal device with a quick fixation mechanism, after placing the centrifuge body 3 into the fixed seat 2 by setting the fixation mechanism 4, only need to rotate the rotating plate 401 into the fixed seat 2, and control the electric telescopic rod 403 to drive the clamping block 404 to engage with the clamping groove 405 to complete the preliminary fixation without alignment operation. Then control the motor 407 to drive the bidirectional threaded rod 408 to rotate, drive the two threaded sleeves 409 to move towards each other, so as to drive the fixing plate 412 to approach the centrifuge body 3 to fix its side wall. Secondly, the threaded rotating rod 6 can also be rotated to drive the pressing plate 7 to move downward to strengthen the fixation of the top of the centrifuge body 3. The fixation effect is good and the operation is simple, solving the problem that the fixation process of the comparative device is inconvenient.
