Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically a test tube stirrer for laboratory use. Background Technology

[0002] Test tubes are used in the laboratory to store samples. Depending on the usage scenario, test tubes can be divided into glass or plastic types, and they are key tools for sample collection, transportation, and pretreatment.

[0003] In the laboratory, staff need to shake test tubes to quickly mix samples. To assist in mixing, staff use a homogenizer for prolonged shaking and stirring. This type of homogenizer has a perforated plate with elastic rubber rings inside. During mixing, the test tubes are placed directly inside the plate, and the rotation of the plate is controlled by a motor or other drive components inside the homogenizer, facilitating long-term operation. However, the size of the plate in this type of homogenizer is fixed and lacks self-adjustment. It cannot be adjusted according to the number of test tubes; it can only accommodate a specific number of test tubes. If the number of holes in the initially customized plate is insufficient, the test tube samples need to be mixed in multiple batches, making it inconvenient to use.

[0004] To address these issues, we provide a test tube stirrer for laboratory use. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] This invention proposes a test tube stirrer for laboratory use, which solves the problem of not being able to adjust the size of the placement plate according to the number of test tubes by means of the cooperation between placement plate one and placement plate two.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a test tube stirrer for laboratory use, comprising a main unit, a rotating shaft rotatably connected inside the main unit, a fixing ring detachably connected to one end of the rotating shaft, and a placement plate fixedly installed on the outer surface of the fixing ring.

[0009] A support plate is fixedly installed at the bottom of the host. A movable plate is slidably connected to the outer surface of the support plate. An installation plate is fixedly installed on the outer surface of the movable plate. A fixed shaft is rotatably connected inside the installation plate. A second fixed ring is detachably connected to one end of the fixed shaft. A second placement plate is fixedly installed on the outer surface of the second fixed ring.

[0010] Both placement plates 1 and 2 have rubber rings fixedly installed inside, and the movable plate has a threaded connection to a fixing bolt inside.

[0011] Furthermore, both the first and second fixing rings are internally threaded with fixing screws, and the first and second fixing rings are fixed by fixing screws.

[0012] Furthermore, the interior of the first and second placement plates has multiple sets of through holes of different diameters, and the rubber ring is fixedly installed inside the through holes.

[0013] Furthermore, the first placement plate and the second placement plate are of the same size, and the first placement plate and the second placement plate are arranged one in front of the other and parallel to each other.

[0014] Furthermore, a limiting plate is fixedly installed on the outer surface of the placement plate, a positioning plate is slidably connected inside the limiting plate, and a positioning ring is fixedly installed on the outer surface of the positioning plate. The positioning rings are symmetrically arranged outside the placement plate.

[0015] Furthermore, a connecting plate is fixedly installed on the outer surface of the second placement plate, and the outer surface of the limiting plate is fixedly installed on the outer surface of the connecting plate.

[0016] Furthermore, a limiting frame is fixedly installed on the outer surface of the support plate, the outer surface of the movable plate is slidably connected to the inner wall of the limiting frame, and one end of the fixing bolt is in contact with the upper surface of the support plate.

[0017] (iii) Beneficial effects:

[0018] Compared with existing technologies, this laboratory tube stirrer has the following advantages:

[0019] I. This laboratory test tube stirrer, through the cooperation between placement plate one and placement plate two, allows the two plates to slide relative to each other. When the lengths of placement plates one and two change, the number of placement holes inside can be adjusted. The number of placement holes can be increased or decreased as needed. When mixing large batches of samples, the number of holes can be increased to reduce the number of stirring times. When mixing small batches or not in use, the number of holes can be reduced to reduce the space occupied. This realizes the function of adjusting the placement plates, which is beneficial for adjusting the size of the placement plates according to the number of test tubes.

[0020] Second, the test tube stirrer used in this laboratory, by setting up a positioning plate and fixing bolts, can quickly fix the first and second placement plates by the mutual abutment of the fixing bolts and the support plate, and can be quickly adjusted by the opposite. The movement of the positioning plate inside the limiting plate can control the stable sliding of the first and second placement plates, thus improving the stability during operation.

Detailed Implementation

[0028] 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.

[0029] like Figures 1-5 As shown, this utility model provides a technical solution: a test tube stirrer for laboratory use, including a main unit 1, a rotating shaft 2 rotatably connected inside the main unit 1, a fixing ring 3 detachably connected to one end of the rotating shaft 2, a placement plate 4 fixedly installed on the outer surface of the fixing ring 3, a rotary motor installed inside the main unit 1, the rotary motor speed being controlled by a speed adjustment knob outside the main unit 1, the speed can be controlled as needed when mixing test tubes in the laboratory, and the placement plate 4 is made of high-strength plastic and is fixed to the fixing ring 3 by bolts and other fasteners.

[0030] A support plate 5 is fixedly installed at the bottom of the main unit 1. A movable plate 6 is slidably connected to the outer surface of the support plate 5. An installation plate 7 is fixedly installed on the outer surface of the movable plate 6. A fixed shaft 8 is rotatably connected inside the installation plate 7. A fixed ring 9 is detachably connected to one end of the fixed shaft 8. A placement plate 10 is fixedly installed on the outer surface of the fixed ring 9. The fixed shaft 8 and the installation plate 7 are connected by a support bearing. The placement plate 10 can rotate stably under the action of the fixed shaft 8.

[0031] Both the first fixing ring 3 and the second fixing ring 9 are threaded with fixing screws 13. The first fixing ring 3 and the second fixing ring 9 are fixed by fixing screws 13. The first fixing ring 3 and the second fixing ring 9 have mounting surfaces inside. The fixing screws 13 are threaded to the rotating shaft 2 and the fixed shaft 8. The fixing screws 13 can be used to fix the first fixing ring 3 and the second fixing ring 9.

[0032] Both placement plate 4 and placement plate 2 are fixedly installed with rubber rings 11 inside. Multiple sets of through holes of different diameters are opened inside placement plate 4 and placement plate 2. The rubber rings 11 are fixedly installed inside the through holes. Placement plate 4 and placement plate 2 are the same size. Placement plate 4 and placement plate 2 are arranged front and back and parallel to each other. Placement plate 4 and placement plate 2 have the same structure. The through holes inside placement plate 4 and placement plate 2 are arranged at equal intervals. When placement plate 4 and placement plate 2 move relative to each other, the through holes inside can overlap in sequence. When two sets of through holes overlap, the interior of placement plate 4 and placement plate 2 is connected. At this time, the test tube can be placed inside the rubber ring 11. The elastic deformation of the rubber ring 11 can fix the test tube.

[0033] The movable plate 6 is internally threaded with a fixing bolt 12. A limit frame 18 is fixedly installed on the outer surface of the support plate 5. The outer surface of the movable plate 6 is slidably connected to the inner wall of the limit frame 18. One end of the fixing bolt 12 contacts the upper surface of the support plate 5. The limit plate 14 can limit the position of the movable plate 6. At this time, the support plate 5 and the movable plate 6 can only move relative to each other in one direction. By rotating the fixing bolt 12, one end of the fixing bolt 12 can be controlled to abut against the support plate 5. At this time, the support plate 5 and the movable plate 6 can be fixed, and it is more convenient to adjust their relative movement.

[0034] A limiting plate 14 is fixedly installed on the outer surface of placement plate 14. A positioning plate 15 is slidably connected inside the limiting plate 14. A positioning ring 16 is fixedly installed on the outer surface of the positioning plate 15. The positioning rings 16 are symmetrically arranged on the outside of placement plate 14. A connecting plate 17 is fixedly installed on the outer surface of placement plate 2 10. The outer surfaces of the limiting plate 14 and the connecting plate 17 are fixedly installed. By using the cooperation of multiple sets of positioning plates 15 and positioning rings 16, placement plate 14 and placement plate 2 10 can be separated and limited. With the limiting of the support plate 5 and the moving plate 6, placement plate 14 and placement plate 2 10 can move stably in parallel, improving the stability when the test tube rotates.

[0035] Working principle: During operation, rotating the fixing bolt 12 adjusts the relative position of the support plate 5 and the moving plate 6. At this time, the positioning plate 15 can slide inside the limiting plate 14, and the placement plate 1 4 and the placement plate 2 10 can slide relative to each other, controlling the through holes inside them to overlap. At this time, the overall length of the placement plate 1 4 and the placement plate 2 10 can be adjusted, and the number of test tubes can be adjusted during inspection. Then, the moving plate 6 is fixed to the outside of the support plate 5 by the fixing bolt 12, and the test tubes are placed inside the rubber ring 11. After starting the main unit 1, the test tubes can be rotated and stirred.
