Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a point-motion mixer. Background Art

[0002] As the main instrument for storing and mixing liquid samples, mixers are widely used in various medical and biological laboratories. They are widely used in experiments such as protein denaturation, nucleic acid extraction and purification, bacterial culture, PCR and enzyme reaction system premixing. Their automated mixing system can replace repetitive manual operations and quickly meet users' mixing and insulation needs.

[0003] However, traditional inching mixers require experimenters to wait for a long time or intervene manually, which further increases the uncertainty of the experiment. Experimenters may lose patience due to long waiting times or frequent operations, or may not be present all the time for other reasons, which may lead to reduced mixing effects.

[0004] Therefore, in order to meet the needs of experimenters for off-machine operation and improve the efficiency and accuracy of mixing operation, the present invention proposes a point-to-point mixer. The point-to-point mixer can achieve automatic mixing of samples through intelligent design. The experimenter only needs to set the mixing parameters and then can perform other operations off-machine. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model embodiment provides a kind of inching mixer, such as Figure 1-3As shown, it includes a base 11, a stand 13, a fixing component, a lifting platform 14, a cover plate 20 and a mixing device 27. The stand 13 is fixed on the base 11, the lifting platform 14 is sleeved on the outer cylindrical surface of the stand 13, a restraining component is provided on the lifting platform 14, the fixing component is provided on the lifting platform 14 away from one end of the restraining component, the fixing component is used to make the lifting platform 14 stay on the outer cylindrical surface of the stand 13 at different heights, the cover plate 20 is provided on the upper side of the upper end surface of the lifting platform 14, a rotating shaft 21 is provided between the cover plate 20 and the lifting platform 14, one end of the rotating shaft 21 is connected to the lifting platform 14 through a bearing 22, and the other end of the rotating shaft 21 is fixedly connected to the lower end of the cover plate 20, and the mixing device 27 is provided on the base 11. The mixing device 27 has the same structure as the prior art, and an eccentric seat 28 is provided in the mixing device 27.

[0022] A placement groove 12 is provided in the base 11 , and the shape of the placement groove 12 matches the mixing device 27 . The experimenter can place the bottom end of the mixing device 27 in the placement groove 12 .

[0023] like Figure 2-Figure 3 As shown, the restraining assembly includes a rubber sleeve 23 and a copper wire bundle 24. The rubber sleeve 23 is provided with two and symmetrically arranged. The copper wire bundle 24 runs through the rubber sleeve 23. One end of the copper wire bundle 24 is fixedly connected to the lifting platform 14, and the other end of the copper wire bundle 24 is spirally wound.

[0024] The fixing assembly includes a slide rod 15 , a slider 16 and a reset spring 17 . The slide rod 15 passes through the lifting platform 14 and is slidably connected to the lifting platform 14 . The slider 16 is fixed at one end of the slide rod 15 away from the lifting platform 14 . The reset spring 17 is fixed between the slider 16 and the lifting platform 14 .

[0025] When holding the slider 16 and causing it to drive the slide bar 15 to slide toward the end away from the lifting platform 14, the end of the slide bar 15 away from the slider 16 is separated from the outer cylindrical surface of the stand 13. At this time, the friction between the lifting platform 14 and the stand 13 is reduced. The experimenter can adjust the height of the lifting platform 14 by moving the lifting platform 14 along the outer cylindrical surface of the stand 13.

At this time, the copper wire bundles 24 on both sides are driven clockwise to continue to be spirally wound. Since the length of the copper wire bundles 24 is fixed, the copper wire bundles 24 on both sides drive the rubber sleeve 23 to shrink and bind the centrifuge tube, and then start the mixing device 27, which drives the centrifuge tube to mix through the eccentric seat 28.
