Further, the spacing distance between adjacent clamping holes and the spacing distance between adjacent grooves are both 2cm.

The middle spring frame strip and the upper spring frame strip are arranged, and the clamping holes and the grooves are arranged, so that the positions of the middle spring frame strip and the upper spring frame strip can be flexibly adjusted according to the aperture of the test tube in the use process of the test tube, the test tube with different specifications can be well limited, and the test tube with different specifications is suitable for being used while being used for test tubes with multiple specifications.

Drawings

FIG. 1 is a schematic diagram of the overall structure of the present utility model;

FIG. 2 is a schematic view of the front structure of a riser;

FIG. 3 is a diagram of the middle spring frame strip;

in the figure, a square bottom plate 1, a vertical plate 2, a middle spring frame strip 3, a mounting rod 4, an upper spring frame strip 5, a concave clamping groove 6, a clamping hole 7, a bent hook 8 and a groove 9.

Detailed Description

The utility model is described in further detail below in conjunction with the drawings of the specification to provide a better understanding of the present technical solution.

The test tube rack convenient to adjust for the laboratory changes the design that the traditional test tube rack is fixed in structure and single in specification, can be flexibly adjusted when being used, is convenient to detach when not being used, ensures the flexibility of use and reduces the occupied space of the laboratory.

The concrete structure is shown in fig. 1-3, and comprises a square bottom plate 1, two vertical upward risers 2 connected with the square bottom plate 1 through mortise and tenon structures, wherein the square bottom plate 1 and the risers 2 form a frame structure of the test tube rack, the mortise and tenon structures are arranged, the disassembly is convenient, and the flexibility of the test tube rack is high. The upper parts of the two vertical plates 2 are connected through the mounting rods 4, specifically, embedded grooves for embedding the end parts of the mounting rods 4 are formed in the two ends of the tops of the vertical plates 2, and the end parts of the mounting rods 4 are pressed into the embedded grooves to realize connection between the two vertical plates 2. For satisfying spacing the placing of test tube, be provided with many middle level spring frame strip 3 at the interval between two risers 2, be provided with many upper spring frame strip 5 at the interval between two installation poles 4, be the crisscross setting between middle level spring frame strip 3 and the upper spring frame strip 5, be convenient for form the space that supplies the test tube to place.

With continued reference to fig. 1-3, the mounting structure between the middle spring frame strip 3 and the riser 2 is specifically: the middle part position of the inner side that two risers 2 are relatively close to all corresponds and has seted up the indent draw-in groove 6 of level form, and the lower limb downwardly extending of this indent draw-in groove 6 has the draw-in hole 7 of interval 2cm, and the both ends of middle level spring frame strip 3, the both ends of upper spring frame strip 5 all are provided with crotch portion 8, crotch portion 8 and the draw-in hole 7 joint cooperation installation at middle level spring frame strip 3 both ends. The specific installation relation between the upper layer spring frame strip 5 and the installation rod 4 is as follows: the corresponding positions of the two mounting rods 4 are respectively provided with a groove 9 for clamping and fixing the bent hook parts 8 on the upper spring frame strips 5 at intervals of 2cm. The middle layer spring frame strip 3 and the upper layer spring frame strip 5 can adjust the distance between the two according to actual use conditions.

In the experimental process, if more than 2 types of test tubes (for example, 10 test tubes with the diameter of 18 times 180mm, 10 test tubes with the diameter of 25 times 250mm and 6 test tubes with the diameter of 30 times 300 mm) are required, a traditional test tube rack is adopted, three test tube racks with corresponding aperture specifications are required, one test tube rack adopting the structure can be satisfied, the number of intervals of inserting the middle layer spring frame strip 3 into the clamping hole 7 of the vertical plate 2 and the number of intervals of inserting the upper layer spring frame strip 5 into the groove 9 of the mounting rod 4 are adjusted according to the aperture size of the test tube, and the positions of correspondingly mounting the two sides of the middle layer spring frame strip 3 or the upper layer spring frame strip 5 can be freely adjusted, so that the test tube rack can be placed by simultaneously using more than two types of test tubes. After the use is finished, the base plate, the vertical plate, the mounting rod and the spring frame strip are all detached, so that the storage is convenient, and the occupation of the laboratory space is reduced.
