Description

Technical Field

[0001] This invention relates to a multi-angle mixing device for test tube samples, which can mix samples in test tubes. It belongs to the field of test tube mixing technology, and specifically relates to a multi-angle mixing device that uses a mixing component to push a swing rod to move up and down, thereby driving the test tube sample tray to move at multiple angles. The device uses a placement component to firmly fix the test tubes on the test tube sample tray and uses the swing of the test tube sample tray to achieve the mixing of samples in the test tubes. Background Technology

[0002] In biological, medical, and other scientific research and testing work, sample mixing in test tubes is a fundamental and crucial operation. However, currently available sample mixing devices for test tubes have significant shortcomings. First, most traditional devices employ a single mixing method, only achieving simple unidirectional or simple oscillation mixing. This results in samples not being fully mixed in all dimensions, leading to poor mixing effects and severely impacting the accuracy and reliability of subsequent experimental results. Second, the frame structure design is unreasonable, making it difficult to withstand the stress generated by prolonged high-intensity mixing motion. This makes them prone to deformation, causing loose connections between components, shortening the equipment's lifespan, and increasing maintenance costs. Furthermore, the lack of an effective buffering mechanism during operation, with the motor directly driving the oscillating components, results in frequent rigid collisions between parts, generating significant noise and vibration, interfering with the experimental environment, damaging components, and reducing the equipment's operational stability.

[0003] Publication number CN222795586U discloses a blood sample mixer, including a test box. The test box has guide rails on its two inner walls, with sliding locking blocks inserted within the guide rails. Square grooves are formed on both walls of the test box, with a limiting groove at the center of each square groove. A lifting block is located inside the test box, and a rotating mechanism is fixed inside the lifting block. A placement block is located at the top of the rotating mechanism, and the placement block is connected to a shaking mechanism. This mixing device uses a gear and rack system to achieve small-amplitude shaking for sample mixing. However, this single mixing method results in the sample not being fully mixed in all dimensions, leading to poor mixing performance. Summary of the Invention

Detailed Implementation Example 1

[0011] The multi-angle mixing device for test tube samples of the present invention is implemented as follows: The multi-angle mixing device for test tube samples of the present invention includes a mixing component and a placement component. The characteristic feature is that the placement component is placed on the mixing component, the placement component is used to firmly fix the test tube on the test tube sample tray (1), and the mixing component is used to mix the sample in the test tube.

The connecting holes correspond one-to-one with multiple corners of the polygonal frame and are placed adjacent to each other. The arc-shaped ball holder (9) is placed below the overall connecting frame (17). The arc-shaped ball holder (9) has a circular ring structure. The outer ring diameter of the arc-shaped ball holder (9) remains unchanged, and the inner ring diameter of the arc-shaped ball holder (9) gradually increases in an arc shape from the top to the bottom. One end of the support frame (10) is fixedly connected to the side of the upper spherical connector (16), and the other end of the support frame (10) is fixedly connected to the bottom surface of the arc-shaped ball support (9). The support frame (10) extends horizontally outward from the end connected to the upper spherical connector (16), then bends vertically downward, then bends vertically again towards the central axis of the arc-shaped ball support (9), and then bends obliquely upward to the other end. There are multiple support frames (10), and the number of support frames (10) is greater than two. The multiple support frames (10) are arranged equidistantly along the circumference of the arc-shaped ball support (9). The overall connecting frame (17) has a long strip structure. Both ends of the overall connecting frame (17) are fixedly connected to the inner side of the upper spherical connector (16). The upper spherical connector (16) is symmetrical about the overall connecting frame (17). The motor (12) is fixed on the integral connecting frame (17). The motor shaft of the motor (12) passes through the integral connecting frame (17) from above to below, and a supporting bearing is placed between the motor (12) and the integral connecting frame (17). One end of the rotating connecting rod (14) is fixedly connected to the motor shaft of the integral connecting frame (17). The rotating connecting rod (14) has a long strip structure. An arc-shaped fixing member (13) is fixedly placed at the other end of the rotating connecting rod (14). The arc-shaped fixing member (13) has a circular ring structure. The side of the arc-shaped fixing member (13) is fixedly connected to the other end of the rotating connecting rod (14). The diameter of the inner ring surface of the arc-shaped fixing member (13) first increases and then decreases in an arc shape from the top end to the bottom end. The center of the inner ring surface of the arc-shaped fixing member (13) coincides with the central axis of the arc-shaped fixing member (13). The swing ball (11) has a spherical structure. The swing ball (11) is mounted on the arc-shaped ball holder (9) and is rotatably connected to the arc-shaped ball holder (9). The center of the swing ball (11) coincides with the central axis of the arc-shaped fixing member (13). The swing disk (8) is fixedly connected to the swing ball (11). The swing disk (8) has a circular ring structure. The inner ring surface of the swing disk (8) is fixedly connected to the spherical surface at the maximum diameter of the swing ball (11). The center of the swing ball (11) coincides with the central axis of the swing disk (8). The swing rod (4) is slidably connected to the connecting hole on the upper spherical connector (16). The swing rod (4) consists of a cylinder and a sphere. The cylinder and the sphere are coaxially arranged, and the diameter of the sphere is larger than the diameter of the cylinder. The sphere is placed above the cylinder. The cylindrical part of the swing rod (4) is slidably connected to the connecting hole of the upper spherical connector (16). The maximum diameter of the spherical part of the swing rod (4) is larger than the diameter of the cylinder. The swing rod (4) is provided in multiple parts, and each swing rod (4) corresponds one-to-one with the connecting hole on the upper spherical connector (16). The limiting block (6) is fixedly connected to the bottom surface of the swing rod (4). The limiting block (6) has a cylindrical structure and is coaxially arranged with the swing rod (4). The lower spherical connector (7) is fixedly connected to the bottom surface of the limiting block (6). The lower spherical connector (7) has a chamfered structure. The flat end of the lower spherical connector (7) is fixedly connected to the bottom surface of the limiting block (6). The arc-shaped surface of the lower spherical connector (7) slides on the top surface of the swing disk (8). A spring (5) is placed between the upper spherical connector (16) and the limiting block (6). The spring (5) is spirally wound around the cylinder of the swing rod (4). One end of the spring (5) is fixedly connected to the bottom surface of the upper spherical connector (16), and the other end of the spring (5) is fixedly connected to the top surface of the limiting block (6). One end of the swing connecting rod (15) is fixedly connected to the swing ball (11), and the intersection of the swing connecting rod (15) and the swing ball (11) coincides with the central axis of the swing disk (8). The other end of the swing connecting rod (15) has a spherical structure and is fitted into the ring of the arc-shaped fixing member (13) and is rotatably connected to the arc-shaped fixing member (13). The placement assembly consists of a hemispherical connector (3), a test tube sample tray (1), and an insertion hole (2). A hemispherical connector (3) is fitted onto the sphere at the top of the swing rod (4). The hemispherical connector (3) has a segmental structure and an open structure at its planar end. The inner diameter of the hemispherical connector (3) is slightly larger than the diameter of the sphere at the top of the swing rod (4). Multiple hemispherical connectors (3) are provided, and each hemispherical connector (3) corresponds to a swing rod (4). The top of the hemispherical connector (3) is fixedly connected to the bottom surface of the test tube sample tray (1). The test tube sample tray (1) has a disc-shaped structure. Multiple hemispherical connectors (3) are arranged at equal intervals along the circumference of the test tube sample tray (1). The test tube sample tray (1) has multiple insertion holes (2), which are in the shape of a disc. The insertion holes (2) are evenly distributed on the test tube sample tray (1). In use, insert the test tubes to be mixed into the insertion holes (2) on the test tube sample tray (1), and then start the motor (12). After the motor (12) starts running, it will drive the rotating connecting rod (14) which is fixedly connected to its motor shaft to start rotating. At the same time as the rotating connecting rod (14) rotates, the arc-shaped fixing part (13) fixed to its other end will also rotate together. When the arc-shaped fixing part (13) rotates, it drives the swing ball (11) to rotate around the central axis of the arc-shaped ball support (9) through the swing connecting rod (15). The swing disk (8) is fixedly connected to the swing ball (11), and the swing... The center of the moving ball (11) coincides with the central axis of the swing disk (8). Therefore, when the swing ball (11) rotates, the swing disk (8) will inevitably rotate as well. During the rotation, the swing disk (8) is placed at an angle, which causes the height of the top of the swing rod (4) to change continuously. As the swing disk (8) continues to rotate at an angle, the swing rod (4) will move up and down, thereby driving the test tube sample tray (1) to tilt and swing up and down. In this way, the sample in the test tube inserted in the test tube sample tray (1) will shake continuously, and finally achieve multi-angle mixing operation of the sample in the test tube. Example 2

[0012] The difference between this embodiment and embodiment 1 is that: an anti-slip strip (18) is fixedly placed on the bottom surface of the lowest end of the support frame (10). The anti-slip strip (18) is long and arranged along the direction of the lowest end of the support frame (10). Each support frame (10) corresponds to a group of anti-slip strips (18). Each group has multiple anti-slip strips (18). The multiple anti-slip strips (18) are arranged at equal intervals along the width direction of the lowest end of the support frame (10). The anti-slip strip (18) is made of rubber. When the device is in use, vibration will inevitably occur. The rubber anti-slip strip (18) can effectively absorb vibration energy and play a buffering role, reducing the transmission of vibration to the placement surface, thereby reducing the noise generated when the device is in operation. At the same time, it reduces the friction between the support frame (10) and the placement surface, which can prevent the bottom of the support frame (10) from being worn due to long-term friction and extend the service life of the support frame (10). Example 3

[0013] The difference between this embodiment and embodiment 1 is that the insertion hole (2) is replaced with insertion holes (19) of different specifications. The insertion holes (19) of different specifications are cylindrical in structure. Multiple insertion holes (19) of different specifications are evenly distributed on the test tube sample tray (1). When in use, the insertion holes (19) of different specifications can accurately match the corresponding insertion holes according to the outer diameter of the test tube. Whether it is a test tube of a regular size or a small or large test tube used in a special experiment, a suitable placement position can be found, which greatly expands the applicability of the device and meets the mixing requirements of different sizes of test tubes in different experiments. The swing ball (11) is rotatably connected to the arc-shaped ball holder (9). The design of the swing disk (8) being fixed to the swing ball (11) and the center of the ball coinciding with the central axis of the swing disk (8) allows the rotation of the swing ball (11) to be directly and stably transmitted to the swing disk (8). As a large planar structure, the swing disk (8) can more effectively drive the swing rod (4) connected to it to swing, providing a stable power basis for realizing the multi-angle swing of the test tube sample tray (1). The swing rod (4) is slidably connected to the connecting hole on the upper spherical connector (16). The swing rod (4) is composed of a cylinder and a sphere. The cylinder and the sphere are coaxially arranged, and the diameter of the sphere is larger than the diameter of the cylinder. The sphere is placed above the cylinder. The cylindrical part of the swing rod (4) is slidably connected to the connecting hole of the upper spherical connector (16). The design that the maximum diameter of the spherical part of the swing rod (4) is larger than the diameter of the cylinder ensures the flexibility of the swing rod (4) and also plays a limiting role to prevent the swing rod (4) from coming out of the connecting hole. It can also provide a stable support point when connected with the hemispherical connector (3) to ensure accurate force transmission. The spring (5) is placed between the upper spherical connector (16) and the limiting block (6). The spring (5) is spirally wound on the cylinder of the swing rod (4). One end of the spring (5) is fixedly connected to the bottom surface of the upper spherical connector (16), and the other end of the spring (5) is fixedly connected to the top surface of the limiting block (6). This design can provide buffer when the swing rod (4) moves, and avoid damage to the components caused by rigid collision. The hemispherical connector (3) is fitted onto the sphere at the top of the swing rod (4). The hemispherical connector (3) has a cleft-circle structure and an open structure at the flat end. The inner diameter of the hemispherical connector (3) is slightly larger than the diameter of the sphere at the top of the swing rod (4). This design allows the hemispherical connector (3) to be easily fitted onto the swing rod (4) while maintaining a certain degree of freedom of movement. When the swing rod (4) moves, the hemispherical connector (3) can flexibly follow its swing and transmit the movement of the swing rod (4) to the test tube sample tray (1). The mixing component can push the swing rod (4) to move up and down, thereby driving the test tube sample tray (1) to move at multiple angles. The test tube is fixed firmly on the test tube sample tray (1) by the placement component. The purpose of shaking the sample in the test tube is achieved by swinging the test tube sample tray (1).

For example, they can refer to fixed connections such as folded edges, rivets, pins, adhesives, and welds; detachable connections such as threaded connections, snap-fit ​​connections, and hinges; integral connections; electrical connections; direct connections; or indirect connections via an intermediate medium; or internal connections between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0015] It should be further noted that, in order to keep the description simple and clear, the above specific embodiments only describe the differences between them and other embodiments. However, those skilled in the art should know that the above specific embodiments are also independent technical solutions.
