Description

Technical Field

[0001] This invention relates to a universal clamping structure for culture containers and an experimental culture rack having the same, which relates to a clamping structure installed on an experimental culture rack to fix experimental containers. It belongs to the field of experimental equipment technology, and particularly relates to a clamping structure that uses a transmission component to drive a clamping component to move, and uses an adjustment component to make two clamping components move in opposite directions to achieve clamping and releasing of the culture container. Background Technology

[0002] In scientific research fields such as biology and medicine, experimental culture racks are crucial equipment for culturing samples such as cells and microorganisms. However, traditional experimental culture racks have revealed numerous drawbacks over long-term use. First, the connections between components are loose, resulting in poor overall stability. In actual use, they struggle to stably support culture containers, and even slight vibrations or external interference can cause the containers to shake or tip over, leading not only to waste of experimental materials but also potentially causing experimental failure. Second, traditional culture racks cannot effectively address the issue of culture medium stratification. Due to gravity and static conditions, oxygen and nutrients in the culture medium are unevenly distributed. The upper layer is rich in oxygen but lacks nutrients, while the lower layer is relatively rich in nutrients but lacks oxygen. This severely affects the growth environment of the cultures, resulting in inconsistent growth states and significant deviations in experimental data.

[0003] CN205774579U discloses a special rack for cell culture experiments, including a base and a rack body. The upper part of the rack body has an inclined plate with multiple grooves of different sizes. A support plate is fixedly connected to the middle of the rack body, and the support plate has multiple bottom holes for cell culture pipettes and bottle cap holes. Multiple grooves are also provided on one side of the rack body. This experimental culture rack is difficult to stably support culture containers. Slight vibration or external interference can cause the culture containers to shake or even tip over. Furthermore, due to gravity and static conditions, the distribution of oxygen and nutrients in the culture medium is uneven. The upper layer is rich in oxygen but lacks nutrients, while the lower layer is relatively rich in nutrients but lacks oxygen, severely affecting the growth environment of the cultures and resulting in inconsistent growth states and significant deviations in experimental data.

[0004] To address the aforementioned issues, the applicant filed a separate Chinese invention patent application entitled "An Experimental Culture Rack," which describes a culture rack capable of constructing a stable frame and using cylinders and electric actuators to provide power for multi-angle rotation, breaking up the stratification of the culture medium to provide an optimal culture environment for the samples. However, the aforementioned experimental culture rack, relying solely on the connection method of inserting culture containers into the sockets, is insufficient to withstand the forces generated during device operation. The culture containers are prone to shaking and may even slip, failing to ensure stability throughout the rotation process. Furthermore, while it can accommodate various common culture container outer diameters to some extent, in actual experiments, culture container specifications are extremely diverse, including not only standard sizes but also special shapes and non-standard sizes, often making effective fixation impossible. Summary of the Invention

[0005] To improve the above situation, the present invention provides a universal clamping structure for culture containers and an experimental culture rack having the same, which provides a clamping structure that achieves clamping and releasing of culture containers by driving a clamping component to move a clamping component through a transmission component and by adjusting a component to make the two clamping components move in opposite directions.

Furthermore, each of the uprights corresponds to a clamping plate, and the clamping plates are arranged at equal intervals along the height direction of the uprights.

[0007] The present invention also relates to an experimental culture rack, which includes a support frame, an auxiliary connecting plate, an electric actuator, two sets of rotating connecting assemblies, a limiting assembly, and a flipping assembly. The feature is that, of the two sets of rotating connecting assemblies, one set is placed at the bottom of the support frame via an auxiliary connecting plate, and the other set is placed at the bottom of the flipping assembly. There are four sets of limiting assemblies, each corresponding to one of the four sides of the top of the support frame. One end of the electric actuator is connected to the rotating connecting assembly at the bottom of the support frame, and the other end is connected to the rotating connecting assembly at the bottom of the flipping assembly. The flipping assembly is movably positioned on the top surface of the support frame. The electric actuator drives the flipping assembly to flip via the rotating connecting assemblies, and the limiting assemblies limit the flipping assembly during its flipping process. The limiting assembly consists of a rotating auxiliary rod, a cylinder, an L-shaped connecting plate, and an L-shaped limiting plate. The rotating auxiliary rod is fixedly placed on the top surface of the square frame of the support frame. The top surface of the rotating auxiliary rod has an arc-shaped groove with an arc radius of less than or equal to half an arc. The top of the side of the rotating auxiliary rod, which is on the same plane as the inner side of the square frame of the support frame, has two locking slots, which are respectively located near both ends of the rotating auxiliary rod.

Detailed Implementation Example 1

[0013] The present invention discloses a universal clamping structure for culture containers and an experimental culture rack having the same, which is implemented as follows: The universal clamping structure for culture containers and the experimental culture rack having the same include two fixed strips (18), an adjustment component, four sets of sliding components, two sets of transmission components, and two sets of clamping components. The feature is that the two fixed strips (18) are fixedly placed on the culture rack (1), the two fixed strips (18) are arranged in parallel and have a certain distance between them, of the four sets of sliding components, two sets of sliding components are placed on one fixed strip (18), and the other two sets of sliding components are placed on another fixed strip (18), and are all arranged close to the two ends of their corresponding fixed strips (18), the two sets of transmission components are placed on the culture rack (1), and the two fixed strips (18) are placed between the two sets of transmission components, and the clamping group The component is connected to two sliding components, and the two sliding components are respectively connected to two fixed strips (18), and both are set close to the same end of the fixed strips (18). The adjustment component is placed on the culture rack (1) and connected to two sets of clamping components. The adjustment component is placed between the two fixed strips (18). The electric push rod drives one set of clamping components to move on the fixed strips (18) through the sliding components. The two sets of clamping components move in opposite directions under the action of the adjustment component. The culture rack (1) is provided with multiple clamping structures for experimental culture racks. The sliding assembly consists of a slide rail (17) and a slider (22). The slide rail (17) is fixedly placed on the fixed strip (18). Preferably, the slide rail (17) is made of a self-lubricating material. The slider (22) is slidably connected to the slide rail (17). The transmission assembly consists of a fixed plate (19) and a telescopic rod (21). The fixing plate (19) is placed on the culture rack (1). One end of the telescopic rod (21) is fixedly connected to the side of the fixing plate (19). Preferably, a damper is added inside the telescopic rod (21). The clamping assembly consists of a movable connecting strip (23), a vertical plate (16), and a clamping plate (15). The movable connecting strip (23) is fixedly connected to the sliders (22) of the two sliding components near the same end on the two fixed strips (18). Preferably, the movable connecting strip (23) has internal reinforcing ribs and is made of carbon fiber composite material. The other end of the telescopic rod (21) is fixedly connected to a movable connecting strip (23) inside a clamping assembly, and is positioned close to both ends of the movable connecting strip (23). The upright plate (16) is fixedly connected to the movable connecting strip (23), and a through hole is opened at the middle of the bottom end of the upright plate (16). One side of the clamping plate (15) is fixedly connected to one side of the top of the upright plate (16), and the distance between the other side of the clamping plate (15) and the upright plate (16) first decreases and then increases from one end to the other. The adjustment assembly consists of a fixed column (20), a Z-shaped connecting rod (25), and two cylindrical connecting rods (24). The fixing column (20) is fixedly placed on the top surface of the culture rack (1). The Z-shaped connecting rod (25) is rotatably connected to the fixed column (20) at the middle. One end of the cylindrical connecting rod (24) is rotatably connected to the top surface of the middle part of the movable connecting strip (23) and is placed below the through hole of the vertical plate (16). The other ends of the two cylindrical connecting rods (24) are rotatably connected to the two ends of the Z-shaped connecting rod (25) respectively. In use, hold the culture container and suspend it above the culture rack (1), positioning the culture container between two clamping plates (15) within a clamping structure. At this time, the entire clamping structure is in its initial state, the telescopic rod (21) is not in motion, and components such as the movable connecting bar (23) and the upright plate (16) are in their initial positions. The distance between the two clamping plates (15) is large enough to accommodate the culture container. Drive the telescopic rod (21) to move the movable connecting bar (23). Since the movable connecting bar (23) is slidably connected to the slide rail (17) on the fixed long bar (18) through the slider (22), the movable connecting bar (23) can move along the direction of the slide rail (17) towards the middle of the fixed long bar (18). The movement of the movable connecting bar (23) will cause the upright plate (16) fixedly connected to its top surface to move synchronously. At the same time, because one end of the cylindrical connecting rod (24) is rotatably connected to the top surface of the middle of the movable connecting bar (23), and the other end is connected to the Z One end of the Z-shaped connecting rod (25) is rotatably connected, so the movement of the upright plate (16) will drive the columnar connecting rod (24) to rotate. As the columnar connecting rod (24) rotates, the angle between it and the Z-shaped connecting rod (25) becomes smaller. Since the entire clamping structure is symmetrically arranged, the movement of one upright plate (16) will be transmitted through the columnar connecting rod (24) and the Z-shaped connecting rod (25), so that the other columnar connecting rod (24) will also rotate synchronously, thereby pulling the other upright plate (16) to move towards the middle of the fixed strip (18). In this way, the two upright plates (16) will gradually approach each other, and the clamping plate (15) fixedly connected to the upright plate (16) will also approach each other, and finally clamp the culture container between the two clamping plates (15) to complete the fixation of the culture container. Example 2

[0014] The difference between this embodiment and embodiment 1 is that: an anti-slip strip (26) is attached to the other side of the clamp (15). The anti-slip strip (26) is made of rubber and has anti-slip texture. When in use, the good elasticity and friction of the anti-slip strip (26) can effectively increase the contact friction with the culture container, ensuring that the culture container is stable and does not slip when clamped. At the same time, the elastic buffering effect of the anti-slip strip (26) can prevent the clamp (15) from directly contacting the culture container, thereby preventing damage to the culture container and protecting the safety of the culture container and the culture inside. Example 3

[0015] The difference between this embodiment and embodiment 1 is that each of the upright plates (16) corresponds to one of the clamps (15), and the clamps (15) are arranged at equal intervals along the height direction of the upright plates (16). When in use, the multiple clamps (15) can provide support and fixation for the culture container at multiple positions, so that the culture container can be stably clamped at each height point. Compared with a single clamp, it can significantly enhance the stability of the culture container during placement, reduce the risk of shaking and tipping, and the multiple clamps (15) can work together to evenly distribute the clamping force on the surface of the culture container, avoid concentrating it at a certain point or area, thereby reducing the possibility of excessive local pressure on the culture container and damage, and better protecting the culture container and the experimental samples inside it. The slide rail (17) is fixed on the top surface of the fixed long strip (18). The slider (22) is slidably connected to the fixed long strip (18) through the slide rail (17), which provides precise guidance for the movement of the moving connecting strip (23). This ensures that the moving connecting strip (23) can only move along the direction of the slide rail (17), avoiding deviation or shaking during the movement process. This ensures the accuracy of the clamping operation and effectively reduces the friction during the movement process, making the movement of the moving connecting strip (23) smoother. This reduces the power required to drive the telescopic rod (21), improves energy utilization efficiency, and also reduces wear between components, extending the service life of the structure. The design of the distance between the other side of the clamping plate (15) and the upright plate (16) decreasing from one end to the other and then increasing makes the clamping plate (15) better adaptable to culture containers of different shapes and sizes. During the clamping process, the clamping plate (15) can fit the shape of the culture container, providing wider applicability and more stable clamping effect. The experimental culture rack is provided with multiple clamping structures for the experimental culture rack. The design of multiple clamping structures for the experimental culture rack being evenly distributed on the top surface of the culture rack (1) allows the experimental culture rack to clamp multiple culture containers at the same time, which improves the efficiency of experimental culture and meets the needs of large-scale experiments. The evenly distributed clamping structures can ensure that each culture container is stably fixed, avoiding the impact of shaking or displacement of the culture container on the experimental results during the culture process, and ensuring the consistency and stability of the culture quality.

[0016] The goal is to achieve the function of clamping and releasing the culture container by moving a clamping component through a transmission component and adjusting the two clamping components to move in opposite directions.

[0017] It should be noted that the general-purpose clamping structure needs to be installed on one of the following experimental culture racks for use; The experimental culture rack includes a support frame (6), an auxiliary connecting plate (8), an electric actuator (12), two sets of rotating connecting components, a limiting component, and a flipping component. The feature is that, of the two sets of rotating connecting assemblies, one set of rotating connecting assemblies is placed at the bottom of the support frame (6) via an auxiliary connecting plate (8), and the other set of rotating connecting assemblies is placed at the bottom of the flipping assembly. There are four sets of limiting assemblies, each set corresponding to one of the four sides of the top of the support frame. One end of the electric push rod (12) is connected to the rotating connecting assembly at the bottom of the support frame (6), and the other end of the electric push rod (12) is connected to the rotating connecting assembly at the bottom of the flipping assembly. The flipping assembly is movably positioned on the top surface of the support frame (6). The electric push rod (12) drives the flipping assembly to flip via the rotating connecting assemblies. The limiting assemblies limit the flipping assembly during the flipping process. The limiting assembly consists of a rotating auxiliary rod (2), a cylinder (3), an L-shaped connecting plate (4), and an L-shaped limiting plate (5). The rotating auxiliary rod (2) is fixedly placed on the top surface of the square frame of the support frame (6). The top surface of the rotating auxiliary rod (2) has an arc-shaped groove with an arc radius less than or equal to half an arc radius. The rotating auxiliary rod (2) and the inner side of the square frame of the support frame (6) are on the same plane, and two slots are opened at the top of the side, and the slots are respectively set near the two ends of the rotating auxiliary rod (2). The L-shaped connecting plate (4) is fixedly connected to the outer side of the support frame (6) and the middle position of the side of the rotating auxiliary rod (2). The cylinder (3) is fixedly connected to the L-shaped connecting plate (4) near one end. An L-shaped limiting plate (5) is fixedly placed at the other end of the cylinder (3). The flipping assembly consists of a flipping connecting frame (7) and a culture rack (1). The flip-connecting frame (7) consists of a cylinder and two long rods. The cylinder is placed on the slot of the rotating auxiliary rod (2). The flip-connecting frame (7) corresponds one-to-one with the rotating auxiliary rod (2). One end of each of the two long rods is fixedly connected to the side of the cylinder near both ends. The two long rods are also locked in the slots of the rotating auxiliary rod (2). The diameter of the cylinder is slightly smaller than the diameter of the arc groove on the rotating auxiliary rod (2). The horizontal part of the L-shaped limiting plate (5) is placed above the cylindrical part inside the flip-connecting frame (7) in the vertical direction and is placed close to it. The bottom surface of the culture rack (1) is fixedly connected to the top surface of the other end of two long rods inside multiple flip-connecting frames (7). The flip-connecting frames (7) are symmetrically arranged about the culture rack (1), and multiple through holes from the top surface to the bottom surface are evenly opened on the culture rack (1). The rotating connection assembly consists of a support plate (9), a direction adjustment transmission ball (10), and a U-shaped connecting block (11). One set of rotating connection components has two support plates (9) fixedly connected to the middle of the bottom surface of the culture rack (1), and another set of rotating connection components has two support plates (9) fixedly connected to the middle of the auxiliary connection plate (8). The direction adjustment transmission ball (10) consists of a ball and four rotating rods. One end of each rotating rod is fixedly connected to the side of the ball. The four rotating rods are arranged equidistantly along the circumference of a central axis of the ball. The rotating rods with two coinciding central axes inside the direction adjustment transmission ball (10) pass through a support plate (9) and are rotatably connected to the support plate (9). The direction adjustment transmission ball (10) is placed between its corresponding U-shaped connecting blocks (11), and the rotating rods with the other two central axes coinciding inside the direction adjustment transmission ball (10) pass through the two vertical plates of the U-shaped connecting block (11) respectively, and are rotatably connected to the U-shaped connecting block (11). The two ends of the electric actuator (12) are fixedly connected to the U-shaped connecting block (11), respectively. In use, the culture container is placed on the culture rack (1) through the evenly spaced through holes. The direction adjustment transmission ball (10) is pre-connected to the support plate (9) and the U-shaped connecting block (11). This structure ensures that the electric push rod (12) can rotate flexibly around the direction adjustment transmission ball (10) below in two mutually perpendicular directions, activating a cylinder (3). After the cylinder (3) operates, it will drive the L-shaped limiting plate (5) connected to it to lock onto the smaller diameter cylindrical part of the flipping connecting frame (7), completing the L-shaped connection. After the positioning plate (5) is positioned, the electric push rod (12) is immediately driven. After the electric push rod (12) is started, the culture rack (1) will rotate around the central axis of the cylinder of the corresponding flipping connecting frame (7). Then the electric push rod (12) is retracted to make the culture rack (1) flat. Multiple cylinders (3) are started in sequence, and the above positioning and rotation operation steps are repeated. That is, after each cylinder (3) is started and the positioning is completed, the electric push rod (12) is driven to make the culture rack (1) rotate. This cycle operation can make the culture rack (1) flip in four directions in sequence. By the cyclic flipping of the culture rack (1) in four directions, the layering phenomenon caused by gravity or static placement of the culture medium can be effectively broken, thereby ensuring that oxygen and nutrients in the culture medium are evenly distributed. Example 2

[0018] The difference between this embodiment and embodiment 1 is that: the bottom of the support frame (6) is fixed with a shock-absorbing pad (13), which is made of rubber. When in use, it can effectively buffer the impact force brought by the device during operation, reduce the friction between the bottom of the support frame and the ground, and at the same time reduce the noise caused by vibration, creating a quieter experimental environment and avoiding noise interference with experimental operation and the precise operation of instruments and equipment. Example 3

[0019] The difference between this embodiment and embodiment 1 is that the culture rack (1) is replaced by an irregularly shaped culture rack (14). The irregularly shaped culture rack (14) is fixedly connected to the top surface of the other end of the two long rods in the multiple flip-connecting racks (7). The irregularly shaped culture rack (14) has multiple through holes with circular and square cross-sections from top to bottom. When used, it greatly expands the scope of application and can meet the placement requirements of culture containers of different shapes. It allows experimenters to no longer be limited to a single shape when selecting culture containers, providing more flexibility for experiments. It can select the most suitable shape of culture container according to the specific requirements of the experiment and the characteristics of the sample. The support frame (6) consists of a square frame and two U-shaped plates. The U-shaped plates are placed at the bottom of the square frame. The two ends of the same U-shaped plate are fixedly connected to the bottom surface of the square frame near the two ends on the same side. The two U-shaped plates are symmetrically arranged about the square frame. The square frame provides a stable planar frame, ensuring that the overall shape of the culture rack is regular and facilitating the installation and layout of each component. The U-shaped plate structure greatly enhances the stability of the support frame, enabling it to bear the weight of the culture rack and culture containers, and is not prone to tilting or shaking, thus providing a solid foundation for the stable operation of the entire experimental culture rack. The top surface of the rotating auxiliary rod (2) has an arc-shaped groove, the height of which is less than or equal to the radius of the arc-shaped groove. The rotating auxiliary rod (2) and the inner side of the square frame of the support frame (6) are on the same plane. Two slots are opened on the top side of the rotating auxiliary rod (2) and the slots are respectively set near the two ends of the rotating auxiliary rod (2). This design can be adapted to the cylinder of the flipping connecting frame (7), providing a smooth track for the rotation of the flipping connecting frame (7), reducing the friction during the rotation process, and making the flipping of the culture rack (1) more stable. The slots set near the two ends are used to lock the long rod of the flipping connecting frame (7), precisely limiting the position of the flipping connecting frame (7), ensuring that it will not be displaced during the rotation process, and ensuring the accuracy and reliability of the flipping action of the culture rack. The direction adjustment transmission ball (10) consists of a ball and four rotating rods. One end of the rotating rod is fixedly connected to the side of the ball. The design of the four rotating rods being equidistantly arranged around the central axis of the ball gives the electric push rod (12) the ability to rotate flexibly in two vertical directions, so that the culture rack (1) can achieve more precise angle adjustment during the flipping process, break the layering of the culture medium more comprehensively, optimize the culture environment, and improve the accuracy and reliability of the experimental results. The electric actuator (12) is positioned between two U-shaped connecting blocks (11), and its two ends correspond one-to-one with the horizontal plates of the two U-shaped connecting blocks (11). This design provides a stable driving force, which, through the coordinated work of the direction adjustment transmission ball (10) and the U-shaped connecting blocks (11), drives the culture rack (1) to rotate around the flipping connecting frame (7). Its power output can be precisely controlled to ensure that the culture rack (1) flips according to the set angle and sequence, effectively achieving functions such as breaking the stratification of the culture medium and increasing the sample loading capacity.

[0020] The goal is to achieve the purpose of building a stable frame through the culture rack (1), and providing power through the cylinder (3) and electric push rod (12) to achieve multi-angle flipping of the culture rack to break the layering of the culture medium and provide an excellent culture environment for the sample.
