Abstract
Description
Technical Field
[0001] This invention relates to an experimental platform with precipitation inhibition and reaction uniformity enhancement functions. It is capable of applying different shaking effects to reagents of different volumes. It belongs to the field of experimental equipment technology. In particular, it relates to an experimental platform that uses the reciprocating rotation of the base around the axis to drive the large bottle of reagent to shake slightly to prevent precipitation and ensure the stability of the reagent properties. The combination of the reciprocating rotation of the roller around the drive shaft to drive the test tube to shake significantly, so as to quickly and thoroughly mix the reagent and improve the uniformity of the experimental reaction. Background Technology
[0002] In scientific research and experimental settings, precise mixing of reagents is crucial for obtaining reliable results. Traditional test tube mixing devices are relatively simple in their operation, focusing solely on mixing reagents within the test tube. The experimenter directly adds the reagent taken from the vial to the test tube and immediately begins mixing. However, in reality, reagents in the vial are prone to stratification due to gravity and component characteristics during prolonged standing. For example, in solutions containing solutes of different densities, lighter components float while heavier components sink. When reagents are drawn from the vial, the concentration and proportion of components will vary depending on the location of the extraction. Even if existing devices can thoroughly mix the liquid in the test tube, the initial unevenness of the reagents used will still lead to deviations in the final experimental data, resulting in reduced reliability and poor reproducibility. These issues severely hinder research progress and accuracy in fields with stringent requirements for reagent precision, such as drug development and chemical analysis.
[0003] Publication No. CN103357335A discloses a test tube shaking mixer, including a mixer body, a vibrator, a rotating shaft, a shaking platform, a motor, and a controller. The vibrator is located inside the mixer body, the rotating shaft and the motor are located on the mixer body, the motor is connected to the rotating shaft, the motor and the vibrator are connected to the controller, and the shaking platform is connected to the rotating shaft. The beneficial effects of this invention are: employing two mixing methods results in excellent mixing effects and significantly reduces costs. The aforementioned test tube shaking device directly adds reagents to the test tube for mixing; however, when removed from a large reagent bottle, due to the long period of settling in the large bottle, layering may occur, leading to inaccurate mixing even if the liquid in the test tube is completely mixed. Summary of the Invention

This platform provides a small-amplitude shaking of the large bottle of reagent by reciprocating rotation of the base around the axis to prevent precipitation and ensure the stability of the reagent properties. The large-amplitude shaking of the test tube by reciprocating rotation of the roller around the drive shaft enables the reagent to be quickly and thoroughly mixed, thereby improving the uniformity of the experimental reaction.

Detailed Implementation Example 1
[0010] The present invention provides an experimental platform with precipitation inhibition and reaction uniformity enhancement functions, which consists of a base (7), a rotary bearing (9), a chassis (8), a vertical rod (10), a connecting plate (11), a container shell (1), a roller (13), a transmission shaft (14), a test tube insertion hole (3), a column (12), a swing rod (6), a rotary motor (5), and a bending connecting block (4). A connecting rod is fixedly placed in the middle of the top surface of the base (7), and a rotary bearing (9) is sleeved on the connecting rod. The chassis (8) is fitted onto the rotary bearing (9), and the chassis (8) is rotatably connected to the connecting rod via the rotary bearing (9). Preferably, the rotary bearing (9) is a high-precision self-aligning ball bearing, and grease is added inside the bearing. One end of the upright (10) is fixedly connected to the chassis (8) and is set close to the side of the chassis (8). There are two sets of uprights (10), and the two sets of uprights (10) are arranged at equal intervals along the circumference of the chassis (8). There are two uprights (10) in each set. The uprights (10) pass through the connecting plates (11) and are fixedly connected to the connecting plates (11). Each connecting plate (11) corresponds to a set of uprights (10). The container shell (1) is fixedly placed at the other end of the upright (10), and the top of the container shell (1) is an open structure. Preferably, the container shell (1) is provided with an elastic fixing clip inside, and the elastic fixing clip is made of silicone. The round roller (13) is placed between the two connecting plates (11). One end of the drive shaft (14) is fixedly connected to the middle of one end of the roller (13). The drive shaft (14) extends through the middle of the connecting plate (11) to the other end. A support bearing is placed between the drive shaft (14) and the connecting plate (11). The other end of the drive shaft (14) is fixedly connected to the test tube rack (2). Each of the test tube racks (2) has multiple test tube insertion holes (3) evenly distributed on it. Preferably, the inner wall of the test tube insertion hole (3) on the test tube rack (2) is provided with a rubber liner. The columns (12) are fixedly placed on the base (7), and the two columns (12) are respectively arranged close to the two opposite sides of the base (7). One end of the swing rod (6) is fixedly connected to the side of the middle part of the roller (13). The swing rod (6) is set perpendicular to the central axis of the roller (13). The two swing rods (6) are arranged at equal intervals along the circumference of the roller (13). The rotary motor (5) is fixedly placed on the side of the column (12). The bending connecting block (4) corresponds one-to-one with the column (12). The bending connecting block (4) consists of a rotating shaft and a bending rod. The rotating shaft passes through the column (12) and is rotatably connected to the column (12). One end of the rotating shaft is fixedly connected to the motor shaft of the rotary motor (5). One end of the bending rod is fixedly connected to the other end of the rotating shaft. The bending rod extends perpendicularly from the end connected to the rotating shaft to halfway point and bends towards the center of the base (7) to the other end. The other end of the swing rod (6) passes through the other end of the bending connecting block (4) and is rotatably connected. The swing rod (6) connected to the other end of the bending rod at halfway point is set vertically. When in use, place the entire device securely on the experimental table, place the large bottle of reagent inside the container shell (1), turn on the rotary motor (5) and start it. The motor shaft begins to rotate. Since one end of one of the bent connecting blocks (4) is fixedly connected to the motor shaft of the rotary motor (5), the rotation of the motor shaft directly drives the bent rod of the bent connecting block (4) to rotate around the rotating shaft. The other end of the bent rod is rotatably connected to the swing rod (6). Its specific bending shape guides the end of the swing rod (6) connected to the bent rod to move around a circular trajectory during the movement. One end of the swing rod (6) is fixedly connected to the round roller (13). Since the swing rod (6) and the central axis of the round roller (13) are set perpendicularly, the movement of the swing rod (6) is transmitted to the round roller (13), driving the round roller (13) to reciprocate around the transmission shaft (14). At the same time, the swing rod (6) exerts a force on the chassis (8) during the movement, causing the chassis (8) to reciprocate around the axis. The reciprocating rotation of the roller (13) around the drive shaft (14) drives the drive shaft (14) fixedly connected to it to rotate. The other end of the drive shaft (14) is fixedly connected to the test tube rack (2), which in turn drives the test tube rack (2) to reciprocate around the drive shaft (14) to achieve the mixing operation of the sample in the test tube. At the same time, as the base (8) reciprocates around the shaft, the reciprocating rotation of the base (8) around the shaft drives the upright rod (10) fixedly connected to it to move together. The movement of the upright rod (10) drives the connecting plate (11) and the container shell (1) fixed at the other end of the upright rod (10) to move. The large bottle of reagent in the container shell (1) rotates in the forward and reverse directions with the movement of the container shell (1) to achieve the mixing operation of the large bottle of reagent. When the liquid in the large bottle of reagent is initially mixed, when it is necessary to take the reagent, the reagent is dispensed into the test tube and the test tube is inserted into the test tube socket (3), which can increase the shaking force of the test tube and improve the mixing effect. Example 2
[0011] The difference between this embodiment and embodiment 1 is that the test tube insertion hole (3) is replaced with insertion holes (15) of different specifications. When in use, more test tubes of different sizes can be accommodated through the insertion holes (15), which greatly enhances the flexibility of the experiment. Example 3
[0012] The difference between this embodiment and embodiment 1 is that the bottom surface of the base (7) is fixedly provided with a shock-absorbing pad (16). When in use, the shock-absorbing pad (16) can reduce the friction between the base (7) and the test bench, which helps to reduce the wear of the base (7), extend the overall service life of the test bench, and reduce the equipment maintenance cost.
[0013] The rotary bearing (9) is a high-precision self-aligning ball bearing with added grease inside. The high-precision self-aligning ball bearing can automatically adapt to the slight deviations that may occur in the transmission shaft (14), reduce friction and wear caused by misalignment of the shaft center, ensure the smoothness and accuracy of the chassis (8) rotation, improve the stability and reliability of the experimental platform operation, and further reduce the friction coefficient inside the bearing, reduce energy loss, extend the service life of the bearing, and at the same time help reduce operating noise, providing a relatively quiet environment for the experiment. The container shell (1) is fixedly placed at the other end of the upright (10). The top of the container shell (1) is an open structure. An elastic fixing clip is provided inside the container shell (1). The elastic fixing clip is made of silicone material, which provides a stable placement space for large reagent bottles, making it easy for experimental personnel to place and take out reagent bottles. The elasticity of the elastic fixing clip can be adaptively adjusted according to large reagent bottles of different shapes and sizes, firmly fixing the reagent bottles and preventing them from shaking or tipping over during rotation, thus ensuring the safety and stability of the reagent mixing process. The inner wall of the test tube insertion hole (3) on the test tube rack (2) is designed with a rubber liner, which can protect the test tube from being scratched inside the test tube insertion hole (3), and at the same time enhance the fixation of the test tube, ensuring that the test tube remains stable during the rotation and swing of the test tube rack (2), preventing the test tube from shaking or falling, and ensuring the safety and accuracy of the experimental operation. The goal is to achieve the following: the large bottle of reagent can be shaken slightly by the reciprocating rotation of the base (8) around the shaft to prevent precipitation and ensure the stability of the reagent properties; the test tube can be shaken significantly by the reciprocating rotation of the roller (13) around the drive shaft (14) to make the reagent quickly and thoroughly mixed and improve the uniformity of the experimental reaction.
