Abstract
Description
Technical Field
[0001] This utility model relates to the field of biological experimental equipment technology, specifically to a torque adapter suitable for culture flask caps. Background Technology
[0002] In biological and chemical laboratories, culture flasks are widely used in experiments such as microbial culture and cell culture. Properly tightening or loosening the cap of the culture flask plays a crucial role in ensuring the flask's airtightness, preventing contamination, and ensuring the stability of the experimental environment. Traditional operation often relies on manual tightening, which typically faces the following problems:
[0003] Torque is difficult to control: When manually tightening caps, the force applied by the operator often varies from person to person, making precise control difficult. Insufficient torque may cause the cap to loosen, allowing outside air, impurities, or microorganisms to enter the culture bottle, contaminating the culture, affecting the accuracy and reliability of experimental results, and even leading to experimental failure, resulting in a huge waste of time, resources, and manpower. For example, in bacterial culture experiments, a loose cap may allow other bacteria to enter, competing with the target bacteria for nutrients, interfering with the normal growth and reproduction of the bacteria, and causing deviations in experimental data.
[0004] Poor ease of operation: Different sizes of culture flask caps and different experimental requirements have different torque requirements. Existing manual operation methods cannot quickly and flexibly adapt to these changes, resulting in cumbersome and inefficient operation. When a large number of culture flasks need to be processed, this inefficient operation method will seriously affect the experimental progress, prolong the experimental cycle, increase experimental costs, and bring many inconveniences to scientific research.
[0005] In view of the above shortcomings, there is an urgent need in the art to design a torque adapter that can solve the torque control problem and improve the ease of operation. Currently, no descriptions or reports of similar technologies to this utility model have been found, nor have similar domestic or international materials been collected. Utility Model Content

Detailed Implementation
[0028] The embodiments of this utility model are described in detail below: These embodiments are implemented based on the technical solution of this utility model, and provide detailed implementation methods and specific operation processes. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
[0029] Existing technologies often suffer from difficulties in controlling torque and poor ease of operation when manually tightening culture bottle caps. To address these issues, one embodiment of this invention provides a torque adapter suitable for culture bottle caps. This torque adapter connects to the culture bottle cap using a docking device, adjusts the torque using a torque adjustment device, and connects to external components using an adapter interface, achieving precise torque control and quick replacement compatibility for culture bottle caps.
[0030] Please also refer to Figures 1-4 .
[0031] Specifically, such as Figure 1 and Figure 3 As shown, the torque adapter for culture flask caps provided in this embodiment may include: a docking device 1, a torque adjusting device 2, and an adapter interface 3; wherein:
[0032] The docking device 1 has a hollow cylindrical structure. The hollow cylindrical structure has an internal thread inside, which is compatible with the external thread on the outside of the culture bottle cap.
[0033] The torque adjustment device 2 includes an adjustment rod 21, an adjustment knob 22 disposed on the adjustment rod 21, and a compression spring 23 disposed inside the adjustment rod 21 and drivenly connected to the adjustment knob 22. One end of the adjustment rod 21 is provided with a circular through hole, and a rotating ring 24 coaxially disposed therein and capable of rotating relative to it is provided. The rotating ring 24 is drivenly connected to the compression spring 23 through a transmission shaft 25. The docking device 1 is detachably coaxially installed inside the rotating ring 24.
[0034] The adapter interface 3 has a standard hexagonal interface structure and is located at the other end of the adjustment rod 21.
[0035] In the above embodiments, the docking device achieves an external threaded connection with the outside of the culture bottle cap; the torque adjustment device drives the compression spring to extend and retract the transmission shaft by rotating the adjustment knob, thereby transmitting the torque to the rotating ring, driving the docking device to rotate, and realizing the tightening or loosening operation of the culture bottle cap; the adapter interface is used to cooperate with external hand tools in special circumstances to apply rotational force to drive the entire torque adapter to rotate, thereby realizing the tightening or loosening operation of the culture bottle cap.
[0036] The technical solutions provided by the above embodiments of this utility model will be further described in detail below with reference to some preferred embodiments.
[0037] like Figure 2 The diagram shown is a schematic representation of the docking device.
[0038] In some preferred embodiments, each docking device 1 has the same outer diameter, while the inner diameter of each docking device 1 is adapted to different culture flask cap sizes. This design allows the torque adapter to adapt to different sizes of culture flask caps, but only requires one torque adjustment device, thus improving tool adaptability and saving costs.
[0039] In some preferred embodiments, a limiting part 11 is provided at the upper edge of the docking device 1. The limiting part is designed to abut against the top of the culture bottle cap, preventing the docking device from being excessively screwed into the culture bottle cap.
[0040] Please also refer to Figure 2 , Figure 3 and Figure 4 .
[0041] In some preferred embodiments, the inner wall of the rotating ring 24 is provided with multiple longitudinal protrusions 27; the outer wall of the docking device 1 is provided with multiple longitudinal grooves 12; when the docking device 1 is installed inside the rotating ring 24, the longitudinal protrusions 27 and the longitudinal grooves 12 are fitted together. This structural design can fix the rotating ring and the docking device during operation, avoid the docking device from sliding and causing invalid rotation, and ensure the reliability of the operation.
[0042] In some preferred embodiments, the adjusting knob 22 has a disc-shaped structure with torque markings on its circumference and a vertical connecting shaft 26 at its center. One end of the compression spring 23 is tightly connected to the free end of the connecting shaft 26 through a blind hole. More preferably, the inner wall of the blind hole is also provided with an internal thread, which mates with the external thread on the connecting shaft 26 to achieve a threaded connection. This threaded connection structure design ensures both the stability of the connection and allows for easy disassembly when necessary.
[0043] The outer wall of the rotating ring 24 has a mounting groove along its circumference. One end of the drive shaft 25 is fixedly connected to the other end of the compression spring 23, and the other end of the drive shaft 25 is embedded in the mounting groove and secured by a snap-fit. This structure prevents the spring from shifting or falling off during rotation.
[0044] When the adjustment knob 22 is rotated, the compression spring 23 is deformed by the torque, and the torque is transmitted to the rotating ring 24 through the transmission shaft 25, thereby driving the docking device 1 to rotate.
[0045] In the above structure, the rotating ring and the docking device are coaxially mounted. The docking device is a hollow cylinder, with its central axis coinciding with the central axis of the rotating ring. The outer wall of the docking device has evenly distributed grooves that engage with the protrusions on the inner wall of the rotating ring, allowing the rotating ring and the docking device to move synchronously during rotation. The internal thread of the docking device matches the external thread of the culture bottle cap. When the rotating ring rotates, the engagement of the grooves and protrusions drives the docking device to rotate, thereby creating a relative threaded motion with the culture bottle cap, enabling the cap to open or close.
[0046] In a specific application example, when the adjustment knob is rotated to the specified torque scale, the compression spring deforms and transmits the torque to the rotating ring, causing the docking device to rotate and open the bottle cap; conversely, releasing the adjustment knob to the initial position causes the docking device to rotate and close the bottle cap.
[0047] In some preferred embodiments, the adjusting knob 22 is also provided with a limit rod. This structure can prevent the adjusting knob from being rotated excessively, ensuring the safety of tool use.
[0048] In some preferred embodiments, the rotating ring 24 is connected to the circular through hole via a bearing assembly, forming a structure capable of relative rotation. This structure can be implemented using existing technology, which will not be described in detail here.
[0049] In some preferred embodiments, a retaining buckle is provided between the rotating ring 24 and the circular through hole to fix the initial position between the rotating ring 24 and the circular through hole.
[0050] In some preferred embodiments, one end of the retaining buckle is fixed to the top of the circular through hole, and the other end of the retaining buckle is detachably installed in a corresponding slot on the top of the rotating ring 24. This structure ensures the relative fixation between the rotating ring 24 and the circular through hole when the entire torque adapter is rotated by applying rotational force with a manual tool.
[0051] In some preferred embodiments, the above embodiments may further include: a standard hexagonal wrench and / or a torque sensor used in conjunction with the adapter interface 3. This is for using external tools to rotate the entire torque adapter in special circumstances, thereby opening or closing the bottle cap.
[0052] The torque adapter for culture flask caps provided in the above embodiments of this utility model allows operators to precisely adjust the torque according to different culture flask cap specifications and experimental requirements through a torque adjustment device. This effectively avoids problems such as damage to the cap due to excessive torque or culture contamination caused by loosening of the cap due to insufficient torque. It improves the sealing performance of the culture flask and the reliability of experimental results, reduces the risk of experimental failure, lowers experimental costs and resource waste, and achieves precise torque control. The adapter employs a docking device that can adapt to different culture flask cap sizes and can be quickly docked, installed, and disassembled with the torque adjustment device. The torque adjustment device enables the docking device to efficiently open and close the culture flask cap, greatly improving experimental operation. This device improves operational efficiency, making it particularly suitable for experiments requiring the processing of large numbers of culture flasks. It helps shorten experimental cycles, accelerate research progress, and is simple and efficient to operate. The adapter interface, with its standard hexagonal interface structure, is compatible with standard hexagonal wrenches. In special circumstances, external tools can be used to quickly open and close the culture flask caps. An external torque sensor detects the torque, making it widely applicable. It can adapt to various sizes of culture flask caps and different experimental operation requirements, offering broad applicability. It can serve as a universal accessory for laboratory culture flask operations, providing laboratory personnel with a convenient and practical tool. This helps standardize experimental procedures, improve overall laboratory efficiency and management, and demonstrates strong versatility.
