Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges for pharmaceutical intermediates, in particular to a small centrifuge for laboratory use. Background Art

[0002] A centrifuge is a mechanical device that uses centrifugal force to separate liquids from solid particles or components of a liquid-liquid mixture. It is mainly used to separate solid particles from liquids in a suspension, or to separate two immiscible liquids with different densities in an emulsion. Laboratories need to use centrifuges when separating samples, and place test tubes on the centrifuge test tube rack for centrifugation. In order to improve the centrifugal effect, the test tube rack is generally tilted during centrifugation.

[0003] The test tube racks on current centrifuges are fixed, and multiple test tube racks arranged in a circle are tilted. When taking out the test tubes, they need to be tilted. When tilting, the test tubes can only be taken out one by one. The relative test tubes will constrain each other, which may affect the efficiency of the centrifugal operation. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a small laboratory centrifuge that can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A small laboratory centrifuge comprises: a centrifuge body, further comprising: a rotating disk rotatably arranged in the centrifuge body; a limiting ring fixedly arranged in the centrifuge body, and the limiting ring is arranged on the lower side of the rotating disk; a motor fixedly arranged in the centrifuge body, and the output end of the motor is fixedly connected to the rotating disk; a placement box arranged on the upper side of the rotating disk; a protective layer arranged on the inner wall of the placement box; a top plate fixedly arranged on the upper end of the placement box; a plurality of test tube racks rotating in a circle on the top plate; and a controller arranged on the centrifuge body.

[0007] In order to facilitate the adjustment of the inclination angle of the test tube rack, an electric telescopic rod is fixedly connected to the placement box, the telescopic end of the electric telescopic rod is fixedly connected to a movable plate, a plurality of fixed rods are fixedly connected to the movable plate, a slide groove and a connecting groove are provided on one side of the test tube rack, and a slider is provided at the end of the fixed rod, and the slider slides in the slide groove.

[0008] In order to facilitate supporting the test tube rack, the slider is further configured to be spherical, and the slider is in contact with the inner wall of the slide groove.

[0009] In order to facilitate the determination of the position of the movable plate, a distance sensor is further provided on the movable plate.

[0010] In order to prevent the liquid from spilling out, the upper end of the placement box is further threadedly connected with a threaded cover.

[0011] Preferably, the test tube rack is connected to the top plate via a hinge.

[0012] Compared with the prior art, the present invention provides a small centrifuge for laboratory use, which has the following beneficial effects:

[0013] 1. This laboratory small centrifuge uses a controller to control the electric telescopic rod to extend, and the electric telescopic rod drives the movable plate to move upward. At this time, the movable plate drives the fixed rod to move upward, and the slider moves upward to tilt the test tube rack. It tilts to the set angle and then stops. Then, the controller controls the motor to drive the rotating disk to rotate, thereby completing centrifugation operations at different tilt angles. When centrifugation is completed, the controller controls the electric telescopic rod to retract, so that the test tube rack is reset, making it easier to take out the test tube, effectively improving its centrifugal efficiency and being suitable for centrifugation operations at different tilt angles.

[0014] 2. The laboratory uses a small centrifuge that uses a distance sensor to obtain the distance between the moving plate and the top plate in real time, thereby determining the position of the moving plate and effectively improving the accuracy of adjusting the tilt angle of the test tube rack.

[0015] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. The utility model facilitates the removal of the test tube, effectively improves its centrifugal efficiency, and is suitable for centrifugal operations at different inclination angles.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] An electric telescopic rod 3 is fixedly connected to the placement box 2, and the telescopic end of the electric telescopic rod 3 is fixedly connected to a movable plate 301. A plurality of fixed rods 302 are fixedly connected to the movable plate 301. A slide groove 206 and a connecting groove 207 are provided on one side of the test tube rack 204. A slider 303 is provided at the end of the fixed rod 302, and the slider 303 slides in the slide groove 206.

[0024] The slider 303 is configured to be spherical, and the slider 303 fits against the inner wall of the sliding groove 206 .

[0025] When the reagent in the test tube is centrifuged, the test tube with the reagent is placed in the test tube rack 204, and then the controller 101 controls the electric telescopic rod 3 to extend, and the electric telescopic rod 3 drives the movable plate 301 to move upward. At this time, the movable plate 301 drives the fixed rod 302 to move upward, and the slider 303 moves upward to tilt the test tube rack 204, so that it stops after tilting to a set angle. Then, the controller 101 controls the motor 102 to drive the rotating disk 103 to rotate, thereby completing centrifugation operations at different tilt angles. When the centrifugation is completed, the controller 101 controls the electric telescopic rod 3 to retract, so that the test tube rack 204 is reset, thereby facilitating the removal of the test tube, effectively improving its centrifugal efficiency, and being suitable for centrifugation operations at different tilt angles.

[0029] The distance between the movable plate 301 and the top plate 203 is acquired in real time by the distance sensor 304 , thereby determining the position of the movable plate 301 , thereby effectively improving the accuracy of adjusting the tilt angle of the test tube rack 204 .
