Abstract

The utility model discloses an adjustable centrifuge tube shelf, and belongs to an auxiliary device of a biological and chemical assay laboratory. The adjustable centrifuge tube shelf comprises a rack body, a centrifuge tube hole, concave grooves, a sliding way, handles, convex grooves, connection rods and an extension face. The adjustable centrifuge tube shelf consists of an upper layer, a middle layer and a lower layer; each layer is provided with a fixed face and a movable face; the movable faces are respectively located on the lower sides of the fixed faces, can move along the sliding way, are positioned through the concave grooves and the convex grooves, and are connected through the connection rods; the two handles are respectively located on the fixed faces and the movable faces; the movable faces move along the sliding way by pushing the handles, so that the convex grooves are located at the different positions of the concave grooves, a size of the centrifuge tube hole is adjusted, and centrifuge tubes with different specifications can be conveniently placed. The adjustable centrifuge tube shelf provided by the utility model has the advantages of simple structure and convenience in use, and can be used for placing the centrifuge tubes of different specifications.

Description

A kind of adjustable centrifuge tube shelf

Technical field

The utility model relates to a kind of biology and Chemical Analysis Lab servicing unit, especially a kind of adjustable centrifuge tube shelf.

Background technology

Biology and Chemical Analysis Lab need to be used a large amount of centrifuge tubes, and commonly used is 100ml, 50ml, three kinds of specifications of 15ml.Owing to needing to use the centrifuge tube of different size in whole experiment flow, thereby need the different centrifuge tube shelf of configuration; To prepare a plurality of centrifuge tube shelfs during experiment and switch back and forth, not only occupy the space of experimental bench, and affected operating efficiency.

Summary of the invention

Can only hold a kind of deficiency of specification centrifuge tube in order to overcome traditional centrifuge tube shelf, the utility model provides a kind of adjustable centrifuge tube shelf.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of adjustable centrifuge tube shelf comprises support body, centrifugal pore, groove, slideway, handle, tongue, connecting rod, the plane of flattening; Centrifuge tube shelf is comprised of upper, middle and lower-ranking, and every layer has stationary plane and all-moving surface, and all-moving surface is positioned at the stationary plane downside, can move along slideway, locates by groove and tongue, connects by connecting rod between all-moving surface.Two handles lay respectively on stationary plane, all-moving surface, shake hands to make all-moving surface to move along slideway by push-and-pull, and then regulate the size of centrifugal pore, in order to place the centrifuge tube of different size.

Groove is positioned on slideway, and tongue is positioned on the plane of flattening of all-moving surface.

Upper, in two-layer stationary plane be provided with the identical centrifugal pore in aperture with all-moving surface, when tongue was positioned at the A position, the centrifugal pore of two faces overlapped fully, was fit to place the 100ml centrifuge tube; When tongue was positioned at the B position, the centrifugal pore intersection of two faces was dwindled, and was fit to place the 50ml centrifuge tube; When tongue was positioned at the C position, the centrifugal pore intersection of two faces was further dwindled, and was fit to place the 15ml centrifuge tube.

The utility model is simple in structure, and is easy to use, realized a kind of centrifuge tube of centrifuge tube shelf placement different size.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is side schematic view of the present utility model.

Fig. 3 is all-moving surface schematic diagram of the present utility model.

The specific embodiment

As shown in Figure 1, a kind of adjustable centrifuge tube shelf, comprise support body 1, centrifugal pore 2, groove 3, slideway 4, handle 5, tongue 6, connecting rod 7, the plane of flattening 8, centrifuge tube shelf is comprised of upper, middle and lower-ranking, every layer has stationary plane and all-moving surface, and all-moving surface is positioned at the stationary plane downside, can move along slideway 4, locate by groove 3 and tongue 6, connect by connecting rod 7 between all-moving surface.Two handles 5 lay respectively on stationary plane, all-moving surface, shake handss 5 all-moving surface is moved along slideway 4 by push-and-pull, and then regulate the size of centrifugal pore, so that the centrifuge tube of placement different size.Groove 3 is positioned on slideway 4, and tongue 6 is positioned on the plane of flattening 8.Upper, in two-layer stationary plane be provided with the identical centrifugal pore in aperture with all-moving surface, when tongue 6 was positioned at the A position, the centrifugal pore of two faces overlapped fully, was fit to place the 100ml centrifuge tube; When tongue 6 was positioned at the B position, the centrifugal pore intersection of two faces was dwindled, and was fit to place the 50ml centrifuge tube; When tongue 6 was positioned at the C position, the centrifugal pore intersection of two faces was further dwindled, and was fit to place the 15ml centrifuge tube.
