The utility model provides a its technical problem take following technical scheme to realize:

a container site switching device for liquid adding and distribution in batches comprises a bottom plate, a support plate and movable container bearing units, wherein the support plate is vertically installed on the bottom plate, a U-shaped groove is formed in the bottom plate, and a plurality of the movable container bearing units are detachably and movably arranged in the U-shaped groove.

And the movable container bearing unit comprises a carrier, a rolling bearing, a limiting module, a limiting column and a gravity module, wherein the rolling bearing is arranged at the rear side of the carrier, the rolling bearing is detachably arranged in the U-shaped groove, the limiting module and the limiting column module are arranged on the carrier, and the gravity module is arranged at the lower side of the carrier and below the rolling bearing.

The limiting module comprises a rear limiting module and a side limiting module, the rear limiting module is arranged on the front side of the rolling bearing on the carrying platform, the side limiting modules are symmetrically arranged on two sides of the carrying platform, and two limiting columns are arranged on the front side of the carrying platform.

The utility model has the advantages that:

1. the device is provided with a U-shaped groove on a bottom plate, and a plurality of movable container bearing units are detachably and movably arranged in the U-shaped groove. Set up the number and the fixed position that portable load cell as required, can adjust the position of container, not only make things convenient for the application of sample, can also reduce the usable floor area of test bench, save space, avoid application of sample and partial shipment sample operation inconvenient to lead to the sample part to spill, or take place the reagent bottle by accident's such as careless accident of bumping down.

2. The gravity center of the movable container bearing unit of the device is always kept at the lowest end of the rolling bearing through the gravity module, and the carrying platform cannot turn over no matter how the rolling bearing slides, and the principle is the same as that of a gyroscope. Utilize spacing module in rear of spacing module and the spacing post of the spacing module one-level of side to carry on spacingly to the container, stability is good, and convenient operation is favorable to experimental good going on to improve experimental accuracy.

3. This device is to big experiment in batches, need not frequently to change the pipette just can be many times with sample partial shipment to a plurality of containers, and be difficult to make mistakes, labour saving and time saving, and in addition, this device is fixed the best interpolation position with portable container load-bearing unit through the operation, has avoided among the cell digestion process because the container position difference leads to because the problem of mistake appears in the difference of interpolation angle.

4. The utility model has the advantages of being scientific and reasonable in design, simple structure, the complicated operation of a plurality of reagent bottles is added to completion prescription composition that can be regular, reduces to make mistakes, improves operating efficiency, and when needs partial shipment multi-bottle cell, this device can accomplish the operation in the short time, and very big degree reduces the liquid and spills outward, has directly reduced the microbiological contamination risk. When a plurality of bottles of cells are packed, the operation of repeatedly blowing and beating the cells once per minute is reduced, the cell damage is reduced, and the cell survival rate is improved. The U-shaped groove and the movable container bearing unit realize the function of continuously adding samples and separating liquid without replacing a pipette, greatly reduces the consumption of consumables, and also reduces the reagent waste phenomenon caused by frequent replacement of residual reagents of the pipette.
