[0030] The utility model provides a sample clamping device, in which, through the action of a driving component, a first jaw and a second jaw can be accurately and flexibly moved closer to or farther from each other, thereby achieving stable clamping of samples of different sizes, shapes and materials. A clamping device of this structure can adapt to diverse experimental needs and improve the efficiency and accuracy of the experiment. Since the clamping component adopts a hinged structure and is combined with the precise control of the driving component, the clamping process is smoother and more reliable, reducing the risk of sample falling off or operator injury due to improper control of the clamping force. The clamping device can be applied to the needs of a variety of experimental scenarios, and can adapt to different types of samples by adjusting the shape and size of the jaws or configuring different adapters. In addition, promoting industry standardization will also help improve the compatibility and interchangeability of clamping devices between different experimental equipment. Example

[0031] The present invention provides a sample clamping device. Figures 1 to 4 As shown, the device body 1 includes a driving component 11; a clamping component 2, the clamping component 2 includes a first clamping member 21 and a second clamping member 22, the first clamping member 21 is arranged on one side of the device body 1, and the second clamping member 22 is arranged on the other side of the device body 1; the first clamping member 21 has a first clamping jaw 211, the second clamping member 22 has a second clamping jaw 221, and the first clamping member 21 and the second clamping member 22 are hinged; wherein the driving component 11 is used to drive the first clamping jaw 211 and the second clamping jaw 221 to move closer to or away from each other.

[0032] Among them, the clamping parts can be made of high-strength, corrosion-resistant and wear-resistant materials, which improves the durability and service life of the clamping device. At the same time, the modular design makes the clamping component 2 easy to disassemble and replace, reduces maintenance costs and time, and improves the maintainability of the equipment. By providing a stable and reliable clamping environment, the device helps to reduce experimental failures or data deviations caused by sample position changes or falling off during the experiment, thereby improving the accuracy and reliability of the experimental results. At the same time, the flexible clamping capability also enables the operator to complete the sample clamping operation more quickly, improving the overall work efficiency.

[0033] like Figure 3 As shown, more specifically, the device body 1 further includes a shell 12, the shell 12 has an opening 121, and part of the clamping assembly 2 is located in the shell 12. In this way, by providing the opening 121 and arranging part of the clamping assembly 2 in the shell 12, the opening 121 can be used to limit the opening and closing degree of the clamping assembly 2.

[0034] Among them, through the design of the opening 121 of the shell 12, the opening and closing degree of the clamping assembly 2 (especially the first clamping member 21 and the second clamping member 22) can be accurately controlled. This limitation ensures that the clamping force is within a safe range, and it will not be too tight to cause damage to the sample, nor too loose to cause the sample to fall off. At the same time, it also helps to maintain the stability of the clamping and reduce unexpected situations during the experiment. Placing part of the clamping assembly 2 in the shell 12 can effectively protect these key components from direct influences of the external environment, such as dust, moisture, corrosive substances, etc. This extends the service life of the clamping assembly 2 and maintains its good working condition. The construction of the shell 12 makes the entire sample clamping device more compact and easy to install and use on a laboratory bench or in an experimental device. It not only reduces the occupied space, but also improves the cleanliness and work efficiency of the laboratory. Since the clamping assembly 2 is partially encapsulated in the shell 12, this design can also reduce vibration and shaking during operation, thereby improving the stability and reliability of the clamping operation. This is particularly important for experiments that require high precision and stability. Such a housing 12 can also serve as an additional safety barrier to prevent the operator from accidentally contacting the sharp parts or moving parts of the clamping assembly 2 during operation. This reduces the risk of pinching or scratching and improves the safety of the experiment. Although the clamping assembly 2 is partially located in the housing 12, the opening 121 design makes cleaning and maintenance work relatively easy. The operator can enter the interior of the housing 12 through the opening 121 to perform necessary cleaning, lubrication or replacement of worn parts of the clamping assembly 2.

[0035] like Figure 2 As shown, more specifically, the first clamping member 21 and / or the second clamping member 22 are hinged to the housing 12 via a connecting rod 23 .

[0036] In this way, the connecting rod 23 acts as a hinge point to firmly connect the clamping member to the housing 12, forming a stable mechanical structure. This structure allows the clamping member to remain stable during the opening and closing process, reduces shaking and vibration, and thus improves the stability and accuracy of the clamping. By hingedly connecting the connecting rod 23 to the housing 12, the opening and closing degree of the clamping member can be controlled more accurately. The length, shape and position of the connecting rod 23 can be accurately calculated and designed to ensure that the clamping member moves within a specific range, thereby achieving effective clamping of the sample while avoiding over-tightening or over-loosening. Since the hinged structure of the connecting rod 23 allows the clamping member to move flexibly within a certain range, the device can adapt to samples of different sizes and shapes. By adjusting the opening and closing degree of the clamping member, various samples from tiny particles to large test tubes can be easily clamped. The hinge of the connecting rod 23 makes the operation of the clamping member easier. The operator can control the opening and closing of the clamping member through simple actions (such as rotating a handle or pushing a button) without complicated adjustments or alignments. As a connecting component, the connecting rod 23 can be made of high-strength, corrosion-resistant materials to ensure its long-term stability and durability. This design reduces the need for maintenance due to loosening or damage of the clamping member, and reduces the cost of use. Since the connecting rod 23 is a key connecting component between the clamping member and the housing 12, its maintenance and adjustment are also relatively easy. When necessary, the connecting rod 23 can be easily disassembled and replaced, or its position can be adjusted to optimize the clamping effect.

[0037] like Figure 2 As shown, the clamping assembly 2 further includes a connecting member 24, and the connecting member 24 is disposed between the first clamping member 21 and the second clamping member 22. More specifically, the connecting member 24 may be a spring.

[0038] In this way, the spring as the connecting member 24 has a natural elastic restoring force. When the clamping assembly 2 releases the sample, the spring can automatically pull the first clamping member 21 and the second clamping member 22 back to the initial position, that is, the state where the clamping jaws are away from each other. This automatic reset structure simplifies the operation process, improves work efficiency, and ensures the stability and consistency of the clamping device after multiple uses.

[0039] By adjusting the rigidity and preload of the spring, the clamping force of the clamping assembly 2 on the sample can be indirectly adjusted. A harder spring or a larger preload can provide a stronger clamping force, which is suitable for clamping heavier or slippery samples; while a softer spring or a smaller preload is suitable for clamping lighter or fragile samples. This adjustability enables the clamping device to adapt to more diverse experimental needs.

[0040] During the clamping process, the spring can also play a buffering role, reducing the impact on the sample caused by the sudden change of the clamping force. This is particularly important for protecting fragile or sensitive samples, and can ensure that the sample is not damaged during the clamping process. The spring as a connector 24 usually has high durability and fatigue resistance. Compared with direct hinges, spring connections can reduce wear and looseness caused by long-term opening and closing operations, thereby extending the service life of the clamping assembly 2. Although the connector 24 (spring) is introduced, this design actually simplifies the overall structure of the clamping assembly 2. The elastic restoring force of the spring replaces the complex mechanical transmission system, making the clamping device more compact and lightweight, and reducing the manufacturing cost. Due to the adjustability and buffer protection characteristics of the spring connection, the clamping device can better adapt to samples of different sizes, shapes and materials. Whether it is a hard test tube or a soft biological sample, stable and reliable clamping can be achieved by adjusting the parameters of the spring. Of course, in addition to the spring, a sample clamping device provided in an embodiment of the utility model can also use other elements that can achieve the same or similar functions.

[0041] like Figure 1 and Figure 2 As shown, more specifically, the first clamping jaw 211 or / and the second clamping jaw 221 may have a plurality of teeth 25. The teeth 25 may enable the clamping jaw to form a plurality of bite points when contacting the sample, thereby increasing the friction and stability of the clamping. This multi-point contact method helps to prevent the sample from sliding or falling off during the clamping process, ensuring the smooth progress of the experiment. The teeth 25 may be designed in different shapes, sizes and arrangements to accommodate samples of different materials and surfaces. For example, for samples with smooth surfaces, finer and sharper teeth 25 may be designed to increase friction; while for samples with rough surfaces, wider and smoother teeth 25 may be used to avoid damaging the sample surface. By adjusting the position and angle of the teeth 25, a more precise clamping of the sample may be achieved. For example, in an experiment where the position or angle of the sample needs to be precisely controlled, the arrangement of the teeth 25 may be used to ensure that the sample is accurately clamped at a predetermined position. Although the design of the teeth 25 increases the friction of the clamping, the reasonable shape and material selection of the teeth 25 may reduce damage to the sample. For example, the use of a clamping tooth 25 made of a soft material or a clamping tooth 25 with a buffer structure can reduce scratches or indentations on the sample surface while ensuring the clamping stability. Due to the dispersed bite effect of the clamping tooth 25, the pressure concentration on the clamping jaw and the sample at a single contact point is reduced, thereby improving the durability of the clamping jaw and the sample. Under long-term use, it helps to extend the service life of the clamping device and the sample.

[0042] like Figure 3As shown, more specifically, the driving assembly 11 includes a motor 111 and an adjusting member 112 , and the motor 111 is used to drive the adjusting member 112 to adjust the distance between the first clamping jaw 211 and the second clamping jaw 221 .

[0043] In this way, the motor 111, as a power source, has the characteristics of high precision and repeatability. Through the precise control of the motor 111, the distance between the first clamping jaw 211 and the second clamping jaw 221 can be fine-tuned, thereby ensuring the precise control of the clamping force. This is particularly important for experimental processes that require highly precise control, such as micro-operation, precision measurement, etc. The introduction of the motor 111 makes it possible to automate the clamping operation. Through programming or external signal control, the motor 111 can automatically complete the clamping and releasing actions without manual intervention. This not only improves work efficiency, but also reduces the errors and uncertainties that may be caused by human operation. During the experiment, it is sometimes necessary to dynamically adjust the clamping force according to the actual situation of the sample. Through the real-time control of the motor 111, the clamping force can be quickly adjusted to adapt to the changes in the sample. This dynamic adjustment capability makes the clamping device more flexible and adaptable. The adjustment member 112 is a transmission component between the motor 111 and the clamping member, and its design is crucial to the clamping effect. The adjusting member 112 can be designed in various forms, such as a screw, a gear, a lever, etc., to achieve different transmission ratios and clamping force adjustment ranges. Reasonable design of the adjusting member 112 can ensure uniform distribution and stable transmission of the clamping force. The clamping device driven by the motor 111 can have overload protection and limit protection functions. When the clamping force exceeds the set range or the clamping member reaches the limit position, the system will automatically stop working to prevent equipment damage or personal injury. This safety mechanism improves the safety and reliability of the experimental process.

[0044] like Figure 1 As shown, more specifically, it may be that it also includes a mounting table 3, and the device body 1 is fixedly connected to the mounting table 3. The mounting table 3, as a supporting structure of the device body 1, can provide a stable installation foundation. By firmly connecting the device body 1 to the mounting table 3, it can be ensured that the clamping device will not shake or move during use, thereby improving the stability and reliability of the clamping. The mounting table 3 can be made of sturdy and durable materials, such as metal or hard plastic, to increase its load-bearing capacity. This enables the clamping device to clamp heavier or larger samples, expanding its application range and usage scenarios. In some experiments, vibration may affect the experimental results. By installing the clamping device on a stable mounting table 3, the interference of external vibration on the clamping device and the sample can be reduced, and the accuracy and reliability of the experiment can be improved. The mounting table 3 not only provides a stable support for the clamping device, but also can be used as part of the experimental table to coordinate with the surrounding environment. Through reasonable design and selection of the color, material and shape of the mounting table 3, the aesthetics and neatness of the entire experimental area can be improved.

[0045] like Figure 4 As shown, more specifically, the first clamp 21 and / or the second clamp 22 have heat dissipation holes 26. High temperature environment will accelerate the aging and wear of the clamp material and shorten its service life. Through the design of the heat dissipation holes 26, the operating temperature of the clamp can be effectively reduced, and the material fatigue and performance degradation caused by high temperature can be reduced, thereby extending the service life of the clamp. The setting of the heat dissipation holes 26 can also facilitate cleaning and maintenance. During the experiment, dust, impurities, etc. may enter the inside of the clamp. Through the heat dissipation holes 26, these dirt can be removed more easily to keep the clamp clean and hygienic. The position, size and number of the heat dissipation holes 26 can be optimized according to the specific structure and use requirements of the clamp. For example, more heat dissipation holes 26 are set in the high temperature area of ​​the clamp, or heat dissipation channels are designed on the side and bottom of the clamp to improve the heat dissipation effect.

[0046] Compared with the prior art, the sample clamping device provided by the embodiment of the utility model can accurately and flexibly move the first jaw and the second jaw closer to or farther away from each other through the action of the driving assembly, thereby achieving stable clamping of samples of different sizes, shapes and materials. The clamping device of this structure can adapt to various experimental needs and improve the efficiency and accuracy of the experiment. Since the clamping assembly adopts an articulated structure and is combined with the precise control of the driving assembly, the clamping process is smoother and more reliable, reducing the risk of sample falling off or injuring the operator due to improper control of the clamping force. The clamping device can be applied to the needs of various experimental scenarios, and can adapt to different types of samples by adjusting the shape and size of the jaws or configuring different adapters. In addition, promoting industry standardization will also help improve the compatibility and interchangeability of clamping devices between different experimental equipment.

[0047] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered within the protection scope of the present invention.
