[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Please refer to Figure 1-4 , Figure 1 A schematic structural diagram of an embodiment of a test tube support device provided by an embodiment of the utility model; Figure 2 A front structural schematic diagram of an embodiment of a test tube support device provided by an embodiment of the utility model; Figure 3 A schematic diagram of the side structure of an embodiment of a test tube support device provided by an embodiment of the utility model; Figure 4 This is a schematic diagram of the back structure of an embodiment of a test tube support device provided by an embodiment of the utility model.

[0024] In a specific embodiment, the test tube support device includes a base 1, a test tube slot plate 2 and a support structure 3, the bottom of the test tube slot plate 2 is rotatably connected to the connection point of the base 1, the side of the test tube slot plate 2 facing away from the base 1 is provided with a plurality of test tube slots for fixing test tubes, the top of the support structure 3 is rotatably connected to the back side of the test tube slot plate 2, the surface of the base 1 facing the back side of the test tube slot plate 2 is provided with a plurality of slots, the spacing between the plurality of slots and the connection point between the bottom of the test tube slot plate 2 and the base 1 is not equal, wherein the bottom of the support structure 3 adjusts the angle between the test tube slot plate 2 and the surface of the base 1 by being clamped in different slots.

[0025] By rotatably connecting the bottom of the test tube slot plate 2 and rotatably connecting the back with the top of the support structure 3, adjusting the different slots of the support structure 3 on the base 1, different angles between the test tube slot plate 2 and the surface of the base 1 are achieved, thereby solving the problem of difficulty in controlling the inclination angle of the test tube when making an inclined surface, and achieving multi-angle inclination of the test tube to meet the needs of making different inclined surfaces. When the inclination angle is 90°, it can be used as a test tube rack to meet the needs of clamping the test tube at any angle, and the test tubes can be fixed in batches at the same time, which greatly improves the convenience of using the test tubes.

[0026] In order to further improve the utilization efficiency of the test tube slots, in one embodiment, a plurality of the test tube slots are arranged in parallel, the test tube slots are U-shaped test tube slots, the spacing between the plurality of the test tube slots is equal, and the transverse dimensions of the plurality of the test tube slots are equal or unequal.

[0027] If they are not set in parallel, according to three-dimensional geometric calculations, the actual angle is not the actual inclination angle, which makes it more difficult to control the subsequent inclination angle. The parallel setting ensures that the error between the actual inclination angle of the test tube and the expected one is small. At the same time, the inclination angle of the test tube can be controlled by only changing the angle between the test tube slot plate 2 and the surface of the base 1, and the difficulty of control is greatly reduced.

[0028] The U-shaped test tube slot can be used to place the test tube, thereby increasing the contact area between the test tube and the test tube slot plate surface 2 and improving the reliability of fixing the test tube.

[0029] By making the spacing between the test tube slots equal, standardized test tube operation can be achieved, reducing the difficulty of operation.

[0030] The present application does not limit the number, lateral dimensions, and shapes of the test tube slots.

[0031] In order to further improve the fixing efficiency of the test tubes, in one embodiment, the test tube supporting device also includes a test tube fixing member 4 arranged on the test tube slot plate 2 for fixing the test tubes in the test tube slots, and the test tube fixing member 4 is a test tube fixing member for fixing the test tubes in a single test tube slot or a test tube fixing member for fixing the test tubes in all the test tube slots, and the test tube fixing member 4 is an elastic test tube fixing member or a test tube clamp test tube fixing member.

[0032] The test tube fixing member 4 is used to fix the test tubes in a single test tube slot or all the test tube slots, thereby improving the reliability of the test tubes and preventing them from slipping out of the test tube slot due to external forces such as collision or slipping out of the test tube slot due to tiny shocks caused by the reaction of substances in the test tubes.

[0033] The present application does not limit the structure, quantity setting method, etc. of the test tube fixing member 4.

[0034] The test tube fixing member 4 can be a structure arranged in each test tube slot, spanning the slot body and directly plugged into the two sides of the test tube slot, so as to fix the test tube in the test tube slot. It can also be an integral fixation, which is also similar to the above-mentioned structure. Moreover, the structure can be a transparent structure or a non-transparent structure. It can be other structures based on heat dissipation and thermal insulation, etc. It can also be a structure such as an elastic band. The elastic band is located in the upper middle part of the test tube slot plate 2 and is fixed at both ends to fix the test tube and prevent it from slipping.

[0035] The test tube groove in the present application can fix the test tube completely or partially. However, in actual use, since the bottom of the test tube needs to be observed in real time during operations such as microbial cultivation, a structure that fixes the test tube partially is generally selected.

[0036] However, in actual use, the contact point between the bottom of the test tube and the base 1 is not at the exact bottom of the test tube. At the same time, as the angle decreases, it is easy to slide out of the test tube slot along the test tube slot, making the fixation ineffective.

[0037] In order to solve the above technical problems, in one embodiment, the base 1 includes a base 1 main body and a bending portion connected to the front end of the base 1 main body, the bending portion is bent toward the surface of the test tube slot of the test tube slot plate 2 where the test tube slot is located, and is used to fix the bottom of the test tube in the test tube slot, and the bending portion is an arc surface bending portion.

[0038] By tilting the base 1, the bottom of the test tube can be fixed, and the bottom of the test tube can be supported as much as possible, thereby improving the fixing efficiency of the test tube.

[0039] The present application does not limit the shape, size, and connection method of the curved portion. An integrated structure or a rotating structure may be used to ensure that the bottom of the test tube is fixed and supported, or other structures may be used.

[0040] The material, length, width, etc. of the support structure 3 are not limited in the present application. Generally, the support structure 3 is a flat rectangular support structure 3, the length of the support structure 3 is 8-12 cm, and the width of the support structure 3 is less than or equal to the width of the test tube slot plate 2.

[0041] The rotating connection structure between the test tube slot plate 2, the base 1, and the support structure 3 in the present application is not limited. In one embodiment, the bottom of the test tube slot plate 2 and the connection between the base 1 are rotatably connected via a first rotating shaft connecting component 5, and the top of the support structure 3 and the back side of the test tube slot plate 2 are rotatably connected via a second rotating shaft connecting component 6.

[0042] In addition to the above structure, other structures are also possible, such as protrusions on both sides of the base 1, and bearings are installed on the protrusions, and the base 1 is connected to the test tube slot plate 2 through the bearings.

[0043] The present application does not limit the size, material, size, spacing, and number of the slots in the base 1. In one embodiment, the length of the base 1 is 20-25 cm, the number of the slots arranged on the base 1 is 5-8, the width of the slots is 1-1.2 cm, the spacing between the first rotating shaft connecting component 5 and the nearest slot is 5-8 cm, the spacing between the first rotating shaft connecting component 5 and the farthest slot is 15-18 cm, and the spacing between two adjacent slots is 1-1.5 cm.

[0044] In order to further improve the efficiency of adjusting the inclination angle, in one embodiment, the test tube support device also includes an angle mark arranged on the base 1 corresponding to the slot, and the angle mark is used to identify the angle between the test tube slot plate 2 and the surface of the base 1 after the bottom of the support structure 3 is snapped into the slot.

[0045] By setting the angle mark, the angle can be adjusted quickly without performing calculations or conversions, thereby improving the accuracy and efficiency of the angle adjustment.

[0046] The present application does not limit the type of angle identification, which may be a digital identification, such as directly identifying the angle value, or dividing a fixed angle into equal parts and then identifying the number, such as 90 degrees is divided into 6 parts, one of which is 15 degrees, so it is sufficient to identify the corresponding number, such as the number 3 represents 45 degrees. It is also possible to use angle identification of different colors, directly set the corresponding color slot on the card slot or nearby, and only need to remember the angle corresponding to the different color angle identification, or other structures, etc.

[0047] In one embodiment, the novel test tube support device includes a base 1 with a slot and a raised front end, a test tube slot plate 2 with a U-shaped groove embedded therein, a support device connected to the test tube slot plate 2, and an elastic band located in the upper middle part of the test tube slot plate 2 and fixed at both ends; the base 1 is connected to the test tube slot plate 2 by a first rotating shaft connecting component; the support structure 3 is connected to the test tube slot plate 2 by a second rotating shaft connecting device structure.

[0048] The base 1 is 22 cm long and has six slots, each of which is 1 cm wide. The first slot is 6 cm away from the end of the shaft connection component. When the support structure 3 is located at the slot, the angle between the test tube slot plate 2 and the base 1 is 90°. The sixth slot is 17.5 cm away from the end of the shaft connection device. When the support structure 3 is located at the slot, the angle between the test tube slot plate 2 and the base 1 is 15°. The distance between every two adjacent slots is 1.3 cm. The front end of the base 1 is tilted 2 cm away from the first shaft connection device to fix the bottom of the test tube.

[0049] The test tube slot board 2 is 20 cm long and has multiple U-shaped grooves embedded in it for placing test tubes; the elastic band is located in the upper middle part of the test tube slot board 2 and is fixed at both ends to fix the test tubes and prevent them from slipping; the support structure 3 is a flat rectangular structure with a length of 10 cm, which is slightly narrower than the width of the test tube slot board 2; the first rotating shaft connecting component 5 connects the base 1 and the test tube slot board 2; the second rotating shaft connecting component 6 connects the support structure 3 and the test tube slot board 2.

[0050] To summarize, the test tube support device provided in the embodiment of the present application realizes different angles between the test tube slot plate and the base surface by rotating the bottom of the test tube slot plate and rotating the back of the test tube slot plate to the top of the support structure, and adjusting the different slots of the support structure on the base.
