Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal devices, in particular to a stem cell centrifuge. Background Art

[0002] Stem cells are a type of cell that has unlimited or immortal self-renewal capabilities and can produce at least one type of highly differentiated daughter cells. When centrifuging stem cells, the cell sample must first be placed in a test tube and then centrifuged using a centrifuge. However, after the centrifugation of the stem cells is completed, since the test tube is inserted into the interior of the centrifuge and only a small portion is exposed to the outside, it is not easy for the staff to apply pressure to the test tube to pull it out, making it troublesome to install and remove. Utility Model Content

[0003] The purpose of the utility model is to provide a stem cell centrifuge to overcome the above-mentioned defects in the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] According to the utility model, a stem cell centrifuge comprises a working box, the upper end of the working box is provided with a cover plate, the card slot card block between the working box and the cover plate is detachably installed, the lower end of the working box is fixedly provided with a power motor, the upper end power of the power motor is connected to a power rod, a working chamber is opened in the working box, the lower side wall of the working chamber is connected with a sliding mechanism, the upper end part of the sliding mechanism is provided with a sleeve evenly distributed in the circumference, a centrifuge tube is sleeved on the sleeve, a support frame is sleeved on the outer periphery of the power rod, the support frame is provided with a ring evenly distributed in the circumference and arranged up and down, the ring is sleeved on the outer periphery of the centrifuge tube, the upper end of the power rod is separately provided with grooves, a clamping block is fixed in the support frame to abut against the groove, the support frame comprises a ring sleeved on the ring and a fixing ring on the power rod, two upper and lower adjacent rings are fixedly connected to the fixing ring by a connecting rod, and two upper and lower adjacent rings are fixedly connected to the fixing ring. The top end of the driving member is provided with a toothed connecting strip which is cooperatively connected with the toothed connecting strip, and the toothed connecting strip is connected with the toothed connecting strip by the toothed connecting strip.

[0006] The beneficial effects of the utility model are:

[0007] The sliding support frame is protruding downward, and a ball is rollingly connected to the lower end of the sliding support frame. The ball abuts against the sliding plate, and the sliding plate is pushed downward under the support of the inclined surface of the lower end of the sliding support frame, so that the sliding plate can adapt to centrifuge tubes of different sizes.

[0008] The contact between the ball and the sliding plate reduces the friction between the sliding plate and the sliding support frame, thereby preventing the sliding support frame from getting stuck and causing the sliding plate to be unable to descend and abut against the centrifuge tube.

[0009] The cover plate is detachably connected through a slot and a block, and is easy to install and use. The support frame is mounted up and down on the centrifuge tube through a collar, which improves the stability of the centrifuge tube during rotation, and increases the stability of the support frame during rotation through a threaded part. The sleeve is supported by a sliding mechanism, and the stability of the centrifuge tube is maintained while reducing the friction of the sleeve, thereby reducing the shaking of the centrifuge tube and facilitating installation.

An annular groove is provided between the rotating ring and the sleeve 20, and the side wall of the annular groove abuts against the abutment balls.

[0022] This program has the following working process:

[0023] The working box 10 is normally opened at the upper end. The user puts the centrifuge tube 18 into the upper opening of the working box 10, and respectively inserts the centrifuge tube 18 into the sleeves 20 evenly distributed in the circumferential direction. The user places the support frame 14 on the upper end of the power rod 13, and inserts the ring 17 at the lower end and the centrifuge tube 18 into the outer periphery of the centrifuge tube 18 correspondingly up and down. Then, the support frame 14 is pushed downward. According to the shape of the groove of the clamping block 15 and the upper end of the power rod 13, the clamping block 15 and the groove on the power rod 13 are made to correspond up and down, so that the clamping block 15 is inserted into the power rod 13. After the support frame 14 is inserted into the bottom end, the user installs the threaded member 16 on the upper end of the power rod 13, and the threaded member 16 is made to fit tightly with the upper end surface of the support frame 14 and the upper end surface of the power rod 13 through threaded cooperation.

[0024] After the installation is completed, the user inserts the cover plate 11 into the upper part of the working box 10, so that the cover plate 11 is engaged with the elastic card block through the card slot, and the cover plate 11 is fixedly set at the upper end opening of the working box 10 to close it;

[0025] The user starts the power motor 12, so that the power motor 12 works to drive the power rod 13 to rotate. The power rod 13, under the contact with the clamping block 15, synchronously drives the support frame 14 sleeved on the power rod 13 to rotate. The support frame 14 drives the centrifuge tube 18 to revolve in the circumferential direction through the collar 17. The lower end of the centrifuge tube 18, under the contact with the sleeve 20, rotates by reducing the friction force through the sliding mechanism 19, thereby realizing the centrifugal work at the centrifuge tube 18;

[0026] During the rotation of the power rod 13, the fixed sleeve 21 slidingly arranged at the fixed frame 28 slides outward under the rotation of the centrifugal force. During the outward sliding of the fixed sleeve 21, the ball 24 at the sliding support frame 23 at the lower end of the fixed sleeve 21 abuts against the inner circumference of the sliding plate 22 sliding on the cover plate 11, pushing the sliding plate 22 to overcome the spring force at the reset spring 26 and slide downward. Under the abutment of the ball 24, the sliding plate 22 moves downward and abuts against the upper end of the centrifuge tube 18. Under the connection of the reset spring 26, the centrifuge tube 18, the sliding plate 22 and the rotating ring 27 rotate synchronously in the circumferential direction, and the sliding plate 22 prevents the liquid inside the centrifuge tube 18 from overflowing.

[0027] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
