Problems solved by technology
[0002] At present, the test tube racks used in laboratories are of different sizes; large test tube racks have low utilization efficiency when fewer test tubes are used, and due to their large volume, large test tube racks are inconvenient to move and are not suitable for use in smaller water baths; small test tube racks The rack is not suitable for experiments that require a large number of test tubes; therefore, it is very important to design a test tube rack that can adjust the amount of test tubes for use in different water baths

Embodiment Construction
[0014] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments;
[0015] A freely assembled test tube rack, including several square test tube racks 1, the four sides of the square test tube rack 1 are symmetrically provided with slots 1-2 and bosses 1-3, the structure of the bosses 1-3 Fitted with the structure of the card slot 1-2, the center of the square test tube rack 1 is provided with a groove 1-4 for storing test tubes;
[0016] The draw-in slot 1-2 is a trapezoidal structure, and the upper end surface of the trapezoidal structure coincides with the side end surface of the square test tube rack 1;
[0017] The structure of the boss 1-3 is the same trapezoidal structure as the slot 1-2, and the upper end surface of the trapezoidal structure coincides with the side end surface of the square test tube...

The invention belongs to the technical field of test tube assemblies, in particular to a free-combined test tube rack. The test tube rack comprises a plurality of square test tube racks (1), clampinggrooves (1-2) and bosses (1-3) are symmetrically arranged on four side surfaces of the square test tube rack (1); wherein the structure of the boss (1-3) is embedded with the structure of the clampinggroove (1-2). According to the device, the square test tube racks can be freely combined according to experiment requirements to form the test tube rack with the proper size, convenience is providedfor the experiment process; meanwhile, the square test tube racks are mutually embedded in a trapezoidal groove embedding mode, which is a stable connection structure, so that the test tube rack is not liable to slide off.
Description
technical field [0001] The invention belongs to the technical field of test tube assemblies, in particular to a freely assembled test tube rack. Background technique [0002] At present, the test tube racks used in laboratories are of different sizes; large test tube racks have low utilization efficiency when fewer test tubes are used, and due to their large size, large test tube racks are inconvenient to move and are not suitable for use in smaller water baths; small test tube racks The rack is not suitable for experiments that require a large number of test tubes; therefore, it is very important to design a test tube rack that can adjust the amount of test tubes used for different water baths. Contents of the invention [0003] In order to effectively solve the problems in the above-mentioned background technology, the present invention proposes a free combination test tube rack, and the specific technical scheme is as follows: [0004] A freely assembled test tube rack...
