Description

Technical Field

[0001] This utility model relates to the field of microbial detection technology, and in particular to a test tube holder. Background Technology

[0002] Microbiology is a branch of modern biology. It studies the basic laws governing the life activities of various microorganisms (bacteria, actinomycetes, fungi, viruses, rickettsiae, mycoplasma, chlamydia, spirochetes, protozoa, and single-celled algae) at the molecular, cellular, or population level, including their morphology, growth and reproduction, physiological metabolism, genetic variation, ecological distribution, and taxonomic evolution. It also applies these laws to fields such as industrial fermentation, medicine and health, and bioengineering.

[0003] In the process of microbial testing, test tubes are needed to hold microbial samples. Test tube racks are required when placing test tubes. However, the size of existing microbial test tube racks is usually fixed, so the number of test tubes they can hold is also fixed. If a large number of test tubes are needed in special circumstances, staff need to find a larger test tube rack, which is quite troublesome. Therefore, we propose a test tube fixing rack.

[0026] like Figure 1-4As shown, this utility model provides a test tube holder, including a support base 5. A vertical plate 1 is fixedly connected to the upper end face of the support base 5, and a placement plate 2 is fixedly connected to the right end face of the vertical plate 1. A second vertical plate 9 is provided on the right side of the support base 5. A second placement plate 3 is slidably connected to the lower end face of the placement plate 2. The right side face of the second placement plate 3 is fixedly connected to the left end face of the second vertical plate 9. Test tube placement openings 4 are provided on the surfaces of the first placement plate 2 and the second placement plate 3 in the same position. The second vertical plate 9 is connected to the support base 5 through an extension mechanism.

[0027] Preferably, a limiting slider 12 is fixedly connected to the rear side of the elongated slide plate 11. The limiting slider 12 is slidably connected to the inner wall of the limiting groove 13 formed in the inner wall of the sliding groove 10. With the cooperation of the limiting slider 12 and the limiting groove 13, the elongated slide plate 11 can be limited and slid within the sliding groove 10.

[0028] Preferably, the front side of the elongated sliding plate 11 is provided with a plurality of positioning holes 14, and the front side of the support base 5 is provided with an installation through hole 8 that communicates with the interior of the sliding groove 10.

[0029] Preferably, a cylindrical cylinder 7 is fixedly connected to the inner wall of the mounting through hole 8, and a movable block 16 is slidably connected to the inner wall of the cylindrical cylinder 7. The movable block 16 can drive the positioning rod 15 to move.

[0030] Preferably, the rear end face of the movable block 16 is fixedly connected to a positioning rod 15 that is slidably connected to the inner wall of the positioning hole 14, and the front end face of the movable block 16 is fixedly connected to a pull rod 18 that passes through the circular cylinder 7 and is slidably connected to the through portion. The positioning rod 15 can cooperate with the positioning hole 14 to limit the elongated slide plate 11 inside the sliding groove 10.

[0031] Preferably, a pull block 6 is fixedly connected to the front end face of the pull rod 18, and a spring 17 is sleeved on the surface of the pull rod 18. The two ends of the spring 17 are fixedly connected to the inner front end face of the cylindrical cylinder 7 and the front end face of the moving block 16, respectively.

[0032] The specific working principle and usage method of this utility model are as follows:

[0033] This utility model provides a test tube holder. When there is a special need to increase the test tube load capacity of the entire test tube holder, the pull block 6 is pulled directly, causing the pull rod 18 to move. The pull rod 18 causes the moving block 16 to slide the positioning rod 15 against the inner wall of the cylindrical cylinder 7, thus separating the positioning rod 15 from the positioning hole 14. At this time, the spring 17 is in a compressed state. After the positioning rod 15 separates from the positioning hole 14, the operator can directly pull the vertical plate 9, causing the vertical plate 9 to move the extension slide plate 11 and the placement plate 3. This causes the second vertical plate 9 to be pulled out from the bottom of the first vertical plate 1. Then, the pull block 6 is released, and the moving block 16 drives the positioning rod 15 to move in the opposite direction under the restoring force of the spring 17. This causes the positioning rod 15 to slide into the positioning hole 14, thereby limiting the extension slide plate 11 inside the sliding groove 10. This can increase the test tube load capacity of the entire test tube rack and avoid the trouble caused by the staff having to find a larger test tube rack to use. Under the action of the limiting sliding groove 13 and the limiting slider 12, the extension slide plate 11 can be limited and slid inside the sliding groove 10.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
