Description

Technical Field

[0001] This utility model relates to the technical field of laboratory instruments, specifically an adjustable multi-layer test tube rack for laboratories. Background Technology

[0002] Currently, the test tube racks commonly used in laboratories are usually straight supports. When there are too many experimental samples, a single test tube rack is often insufficient to accommodate them, and multiple test tube racks are required. These racks are prone to collisions and take up a lot of space. Further investigation of the reaction sometimes requires different quantities of experiments, so different types of test tubes are used. A single type of test tube rack is difficult to meet the needs of the experiment. Utility Model Content

[0003] To address the aforementioned shortcomings, this utility model provides the following technical solution:

[0004] An adjustable multi-layer test tube rack for laboratories includes a base, a fixed block at the center of the base, a sleeve vertically positioned at the center of the fixed block, a telescopic column inside the sleeve, a telescopic rod inside the telescopic column, a primary support plate on the telescopic column, a secondary support plate on the telescopic rod, a plurality of fan-shaped grooves on the primary support plate, an annular groove inside the primary support plate, a turntable inside the annular groove, and a plurality of sets of circular holes of different diameters evenly distributed around the turntable.

[0005] Furthermore, the secondary support plate and the primary support plate are identical in structure except that the secondary support plate does not have a circular groove.

[0006] Furthermore, the sleeve, telescopic column, primary support plate, and secondary support plate are all provided with fixed threaded knobs on their sides.

[0007] Furthermore, the primary support plate between the fan-shaped slots is provided with a circular groove.

[0008] Furthermore, the fan-shaped groove on the secondary support plate corresponds to the circular groove on the primary support plate.

[0009] Furthermore, both the primary support plate and the secondary support plate are made of polyethylene.

[0010] Furthermore, the fixing block below the fan-shaped groove of the primary support plate is provided with a corresponding circular groove.

[0011] The beneficial effects of this utility model are: the test tube rack adjustment structure of this utility model is simple and easy to operate, can adapt to the needs of test tubes of different diameters, reduce the trouble of changing them back and forth, and the multi-layer structure takes up little space, avoiding taking up too much space and affecting the use of the laboratory table.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Combination Figures 1 to 3 Shown:

[0018] A laboratory adjustable multi-layer test tube rack includes a base 1, a fixing block 2 at the center of the base 1, a sleeve 3 vertically positioned at the center of the fixing block 2, a telescopic column 4 inside the sleeve 3 that can rotate within the sleeve 3, a telescopic rod 5 inside the telescopic column 4 that can rotate within the telescopic column 4, a primary support plate 6 on the telescopic rod 5, a secondary support plate 7 on the telescopic rod 5, a plurality of sector-shaped grooves 8 for connecting the upper and lower parts of the primary support plate, and circular grooves 11 on the primary support plate 6 between the sector-shaped grooves 8 for supporting the bottom of the test tubes placed above.

[0019] The primary support plate 6 has an annular groove 9 inside, and a turntable 10 is provided in the annular groove 9. The turntable 10 can rotate in the annular groove 9. The turntable 10 has several sets of circular holes of different diameters evenly arranged in a circular shape. These circular holes are used to place test tubes of different diameters.

[0020] The secondary support plate 7 and the primary support plate 6 are identical in structure except that the circular groove 11 is absent. If necessary, by setting an additional primary support plate structure and a corresponding telescopic structure, the number of test tube rack layers can be increased, thereby increasing the number of test tubes that can be held.

[0021] The sleeve 3, telescopic column 4, primary support plate 6 and secondary support plate 7 are all equipped with fixing threaded knobs 12 on their sides, and the corresponding structures are fixed by turning the fixing threaded knobs 12.

[0022] The fan-shaped groove 8 on the secondary support plate 7 corresponds to the circular groove 11 on the primary support plate 6, which facilitates the placement of test tubes.

[0023] Both the primary support plate 6 and the secondary support plate 7 are made of polyethylene, which is lightweight, inexpensive, and saves on production costs.

[0024] The fixing block 2 below the fan-shaped groove 8 of the primary support plate 6 is provided with a corresponding circular groove 11. It is fixed by rotating the telescopic column 4 and the telescopic rod 5 and turning the fixing screw 12, so that the primary support plate 6 and the secondary support plate 7 are staggered in their structure for accommodating test tubes, effectively placing multiple layers of test tubes in an alternating manner.

[0025] Working principle: When using this test tube rack, first determine the size of the test tubes, adjust the telescopic column and telescopic rod to determine the upper and lower heights, then select a suitable diameter round hole on the turntable for placing the test tubes. Fix the turntable, telescopic column, and telescopic rod by fixing the screw thread knob. Align the fan-shaped groove of the secondary support plate with the round groove of the primary support plate, staggering them to prevent the test tubes on the upper and lower layers from affecting each other. The upper and lower layer structure allows two types of test tubes to be used simultaneously when both layers are in use. This utility model can increase the number of test tubes that can be placed by setting additional layers.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
