Description

Mini vortex mixing appearance

Technical Field

The utility model belongs to the technical field of medical equipment, and particularly relates to a mini vortex mixing instrument.

Background

The mixing instrument is a laboratory sample mixing device, and is mainly applied to the complete mixing and miscibility of more than two liquids or liquids and soluble solid samples.

There is a mixing appearance among the prior art, including base, carousel, eccentric block, pivot and motor, the motor is fixed on the base, and the main shaft and the coaxial fixed connection of pivot of motor, the eccentric block assembly is in the pivot and rotate along with the pivot together, and the carousel rotates and installs in the pivot, during operation, when the motor drove the pivot rotatory, because the effect of eccentric block, makes the epaxial carousel of installation take place eccentric rotation, and sample, the reagent etc. of placing in the carousel then realize the mixing under the eccentric rotation effect of carousel. The mixing instrument with the structure has the advantages that the rotating position of the rotating disc is not limited in the rotating process of the rotating disc, so that the mixing instrument can shake greatly in the working process, and meanwhile, the whole machine cannot stably run in the working process, and the mixing effect is poor.

Disclosure of Invention

The technical problems of the utility model are mainly solved by the following technical proposal: the utility model provides a mini vortex mixing appearance, includes the drain pan, the inside central point of drain pan puts and is equipped with a driving motor, be connected with an eccentric shaft in driving motor's the drive shaft, be connected with a gear on the eccentric shaft, the eccentric shaft rotates with the gear and is connected, the upper end of the inside lateral wall of drain pan is equipped with a ring gear with gear engagement, ring gear driving motor's drive shaft coaxial line sets up, just ring gear and drain pan fixed connection, the upper surface annular array of gear is equipped with a plurality of test-tube racks, the test-tube rack includes fixed part and movable part, fixed part and the upper surface fixed connection of gear, an installation position has been seted up to the outer end of fixed part, the bottom of movable part articulates in the bottom of installation position, two arc draw-in grooves have been seted up from top to bottom in parallel to the lateral wall of movable part, a plurality of the cover is equipped with two ring springs between the test-tube rack, two ring springs card are in two arc draw-in grooves that correspond.

Preferably, a stand column is arranged in the middle of the upper surface of the gear, and a supporting frame is arranged at the upper end of the stand column.

Preferably, the support frame is connected to a fixing portion in each test tube rack.

Preferably, a guard plate is arranged on the bottom shell.

The utility model has the beneficial effects that: through the structure of the toothed ring and the gear, the eccentric rotation of the gear can be limited by the toothed ring in the process of driving the gear to eccentrically rotate by the driving motor, so that larger vibration caused by larger centrifugal force generated by eccentric rotation is prevented, and meanwhile, the gear is meshed with the toothed ring in the rotating process, so that the stability of the test tube rack in the rotating process can be effectively ensured; through setting up the test-tube rack that can move about, utilize annular spring to tighten the test-tube rack, mobilizable test-tube rack makes things convenient for the test tube to put into the test-tube rack and fixes.
