Description

Technical Field

[0001] The invention relates to an experimental device, in particular to a centrifuge tube rack with adjustable aperture. Background Art

[0002] In biological analysis work, centrifuge tubes of different specifications are needed, and the commonly used specifications are 50mL and 15mL. Existing centrifuge tube racks include different specifications, such as 50mL and 15mL double-layer centrifuge tube racks. During operation, the corresponding specifications of the centrifuge tube racks are equipped according to the size of the centrifuge tubes. That is, the centrifuge tube racks in existing laboratories can only hold one specification of centrifuge tubes. Centrifuge tubes of multiple specifications need to be equipped with centrifuge tube racks of multiple specifications, resulting in problems such as too many tube racks, difficult placement, space occupation, and a large number of experimental personnel, and easily causing waste of resources; and different centrifuge tube racks need to be switched during use, resulting in low work efficiency. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a centrifuge tube rack with adjustable aperture, comprising a support base, two support side plates symmetrically arranged on both sides of the support base and parallel to each other, and at least one layer of support frame horizontally arranged between the support side plates on both sides;

[0004] The support frame comprises a fixed plate fixedly arranged on the upper layer and a movable plate slidably arranged on the lower layer, and the fixed plate and the movable plate are both provided with centrifugal holes corresponding to each other one by one.

[0005] The inner surface of the supporting side plate is provided with a slide groove corresponding to the two ends of the movable plate, the bottom of the slide groove is provided with at least two positioning holes 1, and the two ends of the movable plate are provided with a positioning pin 1 corresponding to the positioning hole 1 through a spring 1. The end of the movable plate is provided with a handle.

[0006] Wherein, two locating pins are arranged at both ends of the fixing plate through two springs, and two locating holes corresponding to the two locating pins are arranged on the supporting side plate. Wherein, a handle is arranged at the end of the fixing plate.

[0007] Through the above technical scheme, the present invention can be used for centrifuge tubes of various specifications by setting the centrifugal hole diameter of the centrifuge tube rack to be adjustable, thereby greatly improving the application range of the centrifuge tube rack and reducing cost investment and space occupancy, and facilitating the replacement of a new movable plate.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] Embodiment 1:

[0016] refer to Figures 1 to 4 The present invention provides a centrifuge tube rack with adjustable aperture, comprising a support base 30, two support side plates 10 symmetrically arranged on both sides of the support base 30 and parallel to each other, and at least one layer of support frame horizontally arranged between the support side plates 10 on both sides; the support frame comprises a fixed plate 21 fixedly arranged on the upper layer and a movable plate 22 slidably arranged on the lower layer, and a handle is arranged at the end of the movable plate 22, and centrifuge holes 23 corresponding to each other are arranged on the fixed plate 21 and the movable plate 22. The inner surface of the support side plate 10 is provided with a slide groove 11 corresponding to the two ends of the movable plate 22, and at least two positioning holes 12 are arranged at the bottom of the slide groove 11, and the two ends of the movable plate 22 are provided with positioning pins 221 corresponding to the positioning holes 12 through springs 222.

[0017] The working principle of this embodiment 1 is as follows:

[0018] Take 50mL and 15mL centrifuge tubes as examples: when the positioning pin 221 of the movable plate 22 of each layer of the support plate is correspondingly engaged with the positioning hole 12 at position a in the slide groove 11 of the supporting side plate 10, the centrifugal holes 23 on the fixed plate 21 of each layer of the support plate are aligned with the centrifugal holes 23 on the movable plate 22, so that they can be used for supporting and positioning 50mL centrifuge tubes; when the movable plate 22 is pulled outward by the handle to slide along the slide groove 11 and the positioning pin 221 of the movable plate 22 is correspondingly engaged with the positioning hole 12 at position b in the slide groove 11 of the supporting side plate 10, the centrifugal holes 23 on the fixed plate 21 of each layer of the support plate are misaligned with the centrifugal holes 23 on the movable plate 22, so that the overlapping part of the upper and lower centrifugal holes 23 is reduced for supporting and positioning 15mL centrifuge tubes.

[0019] Embodiment 2:

[0020] Based on Example 1, two locating pins are provided at both ends of the fixing plate 21 through two springs, and two locating holes corresponding to the two locating pins are provided on the supporting side plate 10. A handle is provided at the end of the fixing plate 21 to facilitate replacement of a new fixing plate 21.

[0021] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to the above embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
