Description

Technical Field

[0001] This utility model relates to the technical field of centrifuge tube placement boxes, and in particular to a multi-specification centrifuge tube placement box. Background Technology

[0002] Centrifuge tube holders are laboratory equipment used to store and organize centrifuge tubes of different sizes. In the experimental field, centrifuge tubes serve as carriers for sample storage, reactions, and centrifugation. Proper placement plays a significant role in the orderly conduct of experimental procedures and sample safety. Centrifuge tube holders are usually made of rigid plastic or metal materials. The box body has multiple positioning holes or slot structures inside to fix the centrifuge tubes vertically, preventing them from tipping over or rolling. This prevents the centrifuge tubes from being damaged due to collisions with each other, and facilitates the quick identification and retrieval of different samples by experimental personnel, ensuring the standardization and efficiency of experimental operations.

[0003] With the increasing sophistication of scientific research experiments, it is often necessary to use centrifuge tubes of various sizes simultaneously during the experiment. Traditional single-size storage boxes cannot meet the needs. Multi-size centrifuge tube storage boxes improve the flexibility of experimental operations. Researchers can place reaction tubes, sample storage tubes, and centrifuge tubes together to reduce retrieval time. In the field of clinical testing, multi-size storage boxes integrate sample tubes for different testing items, effectively avoiding sample confusion and significantly improving testing efficiency.

[0004] Existing multi-size centrifuge tube holders still have shortcomings in centrifuge tube compatibility. Some current holders achieve multi-size adaptation by setting adjustable partitions or stepped positioning holes. Adjusting the spacing by moving the partitions or using different hole diameters to adapt to the outer diameter of centrifuge tubes alleviates the compatibility problem to some extent. However, since the adjustable partitions rely on manual adjustment and lack a precise positioning structure, they are prone to loosening and displacement during frequent use, resulting in unstable centrifuge tubes. The positioning structure of existing holders is mostly made of rigid materials. When there is a slight difference in size between the outer diameter of the centrifuge tube and the positioning hole, there is a risk of compression deformation due to excessive tightness, or the centrifuge tubes may shake inside the holder due to excessive looseness. Especially during centrifugation, centrifuge tubes are prone to collision and breakage, which seriously affects the integrity of experimental samples and the accuracy of experimental results.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a multi-specification centrifuge tube placement box, including a placement rack 1 as a supporting structure for the placement box. An adjustment mechanism 2 is provided at the top of the placement rack 1 to adapt to the placement and adjustment of centrifuge tubes of different specifications. A cooling mechanism 3 is fixedly connected to the inner side of the placement rack 1 to control the temperature of the centrifuge tubes placed in the box. A shock-absorbing mechanism 4 is provided at the bottom of the placement rack 1 to effectively buffer external vibrations and prevent damage to the centrifuge tubes due to vibration. A partition mechanism 5 is fixedly connected to the bottom of the shock-absorbing mechanism 4 to protect the bottom of the placement box. The adjustment mechanism 2 includes multiple support rods 201, which serve as the supporting skeleton of the adjustment mechanism 2 and provide a sliding track for the slider 203 component. Both ends of the multiple support rods 201 are fixedly connected to the inner side of the placement rack 1 to ensure a stable connection between the adjustment mechanism 2 and the placement rack 1. Slide grooves 202 are provided on the left and right sides of the multiple support rods 201 to provide a guiding path for the sliding of the slider 203. Multiple support rods 201 are slidably connected to the middle of their outer sides with sliders 203. The position of the centrifuge tube is adjusted by sliding the sliders 203. Multiple limit holes 205 are opened on the inner side of the multiple support rods 201. These holes cooperate with limit bolts 204 to fix the position of the sliders 203. Limit bolts 204 are slidably connected to the outer side of the multiple sliders 203. Tightening the limit bolts 204 fixes the sliders 203 in the appropriate position. The other side of the multiple limit bolts 204 passes through one side of the sliders 203 and is slidably connected to the inner side of the corresponding limit hole 205 to ensure the reliability of the limit fixation. A fixing ring 206 is fixedly connected to the middle of the inner side of the multiple sliders 203 for directly clamping and fixing the centrifuge tube. A protective pad 207 is fixedly connected inside the multiple fixing rings 206 to prevent the fixing rings 206 from scratching the surface of the centrifuge tube. A connector 208 is fixedly connected to one side of the multiple limit holes 205 for easy connection and expansion with other components.

[0037] Specifically, when centrifuge tubes of different sizes need to be placed, the user loosens the limiting bolt 204 on one side of the slider 203, and slides the slider 203 up or down along the guide of the slide groove 202 to adjust it to the position suitable for placing the centrifuge tubes. After adjustment, the user tightens the limiting bolt 204 so that it is inside the corresponding limiting hole 205, thereby fixing the slider 203. The centrifuge tubes are then placed in the fixing ring 206, which clamps and fixes the centrifuge tubes. The protective pad 207 prevents scratches on the surface of the centrifuge tubes. The cooling mechanism 3, which is fixedly connected to the inside of the placement rack 1, starts to work to control the temperature of the centrifuge tubes in the box. To meet the temperature requirements for centrifuge tube storage, the bottom of the placement rack 1 is equipped with a shock-absorbing mechanism 4. When external vibration occurs, the structure effectively buffers the vibration, reduces the impact of vibration on the centrifuge tubes, and prevents the centrifuge tubes from being damaged by vibration. The partition mechanism 5 connected to the bottom of the shock-absorbing mechanism 4 can protect the bottom of the placement box, reducing wear and collision damage when the bottom of the placement box contacts the ground. The connector 208 connected to one side of the limiting hole 205 facilitates connection and expansion with components, enhances the functional versatility of the placement box, and realizes the stable placement, temperature control, and shock absorption protection of centrifuge tubes of different specifications in the multi-specification centrifuge tube placement box.

[0038] Reference Figure 1 , Figure 3 and Figure 5 The cooling mechanism 3 includes a cooling controller 301 and cooling plates 303. The bottom of the cooling controller 301 is fixedly connected to the inside of the placement rack 1. The cooling controller 301 controls and manages the placement box.

A transmission line 304 is connected to the right side of the cooling plate 303 for transmitting the cold energy generated by the cooling plate 303 to the bottom inside of the placement rack 1. Two contact blocks 305 are connected to the right side of 04, which serve as a connection and conduction mechanism, enabling power to be smoothly transmitted to the battery 306. The battery 306 is slidably connected to the right side of the two contact blocks 305 to provide power to the cooling mechanism 3. A partition 307 is provided on the outside of the battery 306 to isolate and protect the battery 306 and prevent it from being hit or interfered with. An expansion component 308 is provided on the right side of the cooling controller 301. The expansion component 308 is used to improve the cooling mechanism 3 when the battery 306 is out of power, using multiple connectors 208 for cooling, thereby improving the applicability and flexibility of the placement box.

[0039] Specifically, when the solution inside the centrifuge tube needs to be stored in a low-temperature outdoor environment, the cooling controller 301 transmits a cooling control signal through the connecting line 302, which is then transmitted to multiple cooling plates 303. Upon receiving the power and control signals, the cooling plates 303 begin to operate, generating a cooling effect and creating a cooling environment for the centrifuge tubes. The cooling energy generated by the cooling plates 303 is transmitted to the inner bottom of the placement rack 1 through the transmission line 304, bringing the interior of the placement rack 1 to the required low-temperature conditions. The two contact blocks 305 serve as a connection and conduction point, smoothly transmitting power to the battery 306. The battery 306 continuously provides power to the cooling mechanism 3, ensuring its stable operation. The partition 307 isolates and protects the battery 306, effectively preventing interference and ensuring the safety and lifespan of the battery 306. The expansion component 308 functions when the battery 306 is depleted, utilizing multiple connectors 208 for cooling, improving the applicability and flexibility of the placement box, and ensuring that the cooling mechanism 3 can normally achieve its cooling function under different power supply conditions, meeting the cooling needs of the centrifuge tubes.

[0040] Reference Figure 1 , Figure 2 and Figure 6The expansion component 308 includes a second transmission line 3081, which is used to transmit signals or electrical energy.

The separation mechanism 5 includes an anti-slip plate 501. The top of the anti-slip plate 501 is set at the bottom of the multiple mounting blocks 404. The anti-slip plate 501 prevents the equipment from sliding when placed and plays a stabilizing role. A support frame 502 is fixedly connected to the top of the anti-slip plate 501. The support frame 502 provides a support frame for the separation mechanism 5. A transparent plate 503 is fixedly connected to the inner four sides of the support frame 502. The transparent plate 503 facilitates the observation of the internal condition of the centrifuge tube. A cover plate 505 is fixedly connected to the top of the support frame 502. The cover plate 505 protects the internal equipment. A protective component 504 is provided on the rear side of the support frame 502 and the rear side of the cover plate 505. The protective component 504 enhances the protection of the internal equipment. A display component 506 is provided on the top left side of the cover plate 505. The display component 506 facilitates the user to view the storage time of the centrifuge tube.

[0041] Specifically, during equipment operation, transmission line 3081 in expansion component 308 transmits signals and electrical energy to expansion connector 3082. Expansion connector 3082 enables flexible connection and expansion of various lines, providing functional expansion for the equipment. Power socket 3083 connects to an external power source, ensuring a stable power supply for the equipment. Data cable connector 3084 ensures smooth data communication between the equipment and external systems. When the equipment is subjected to vibration during operation, the shock absorption mechanism 4 activates. Support plate 401 transmits the vibration downwards, and springs 403 fixed by multiple fixing plates 402 release the vibration. The shock absorber 4 is securely mounted on the corresponding component. In the partition mechanism 5, the anti-slip plate 501 is placed at the bottom of the mounting block 404 to prevent the equipment from sliding and provide a stable placement environment. The support frame 502 serves as a support frame. The transparent plate 503 allows operators to observe the internal condition of the centrifuge tube at any time and keep track of the operating status. The cover plate 505 and the protective component 504 work together to reduce the risk of damage to the equipment from external factors. The display component 506 displays the centrifuge tube storage time information in real time.

[0042] Reference Figure 1 , Figure 2 and Figure 5 The centrifuge tubes of various sizes are placed in a box. The protective component 504 includes two connecting blocks 5041. The front sides of the two connecting blocks 5041 are respectively fixedly connected to the rear sides of the support frame 502 and the cover plate 505, serving to connect the cover plate 505 and the support frame 502. The rear sides of the two connecting blocks 5041 are fixedly connected to limit rings 5042 to limit the position of the fixed shaft 5043. The two limit rings 5042 are rotatably connected to the same fixed shaft 5043, allowing the component to rotate flexibly. The display component 506 includes an electronic timer 5061. The bottom of the timer 5061 is fixedly connected to the top left side of the cover plate 505 for timing. Multiple buttons 5062 are fixedly connected to the top rear side of the electronic timer 5061 for easy operation and setting of time parameters. The top of the electronic timer 5061 is fixedly connected to the display panel 5063 for displaying timing information. The left side of the transmission line 3081 is connected to the right side of the cooling controller 301 to ensure that the transmission line 3081 is firmly fixed. The top of the transmission line 3081 is fixedly connected to the top front side of the partition plate 307 for easy maintenance of the transmission line 3081.

[0043] Specifically, first, the centrifuge tubes are placed in the appropriate placement slots within the support frame 502. The upper connecting block 5041 is located behind the cover plate 505, and the lower connecting block 5041 is fixed to the rear of the support frame 502. The limiting rings 5042 on the rear of the two connecting blocks 5041 limit the position of the fixed shaft 5043, allowing the cover plate 505 to rotate flexibly around the connecting block 5041 via the fixed shaft 5043, facilitating opening and closing. According to experimental needs, the user sets the time parameters via the button 5062 of the electronic timer 5061. The electronic timer 5061 starts timing and displays the timing information on the display panel 5063. When the transmission line 2 3081 fails to receive power, it can be inspected and repaired promptly by checking the transmission line 2 3081 next to the partition 307.

[0044] Working principle: When centrifuge tubes of different sizes need to be placed, the user loosens the limiting bolt 204 on one side of the slider 203, and slides the slider 203 up or down along the guide of the slide groove 202 to adjust it to the position suitable for placing the centrifuge tubes. After adjustment, tighten the limiting bolt 204 so that it is inside the corresponding limiting hole 205, thereby fixing the slider 203. Place the centrifuge tubes in the fixing ring 206, which clamps and fixes the centrifuge tubes. The protective pad 207 prevents scratches on the surface of the centrifuge tubes. The cooling mechanism 3 starts to work, cooling the centrifuge tubes in the box. Temperature control ensures that the centrifuge tubes are stored at the correct temperature. When external vibrations occur, the shock absorption mechanism 4 comes into play, effectively buffering the vibrations through its own structure to reduce the impact of vibrations on the centrifuge tubes and prevent them from being damaged by vibrations. The partition mechanism 5 connected to the bottom of the shock absorption mechanism 4 can protect the bottom of the placement box, reducing wear and collision damage when the bottom of the placement box comes into contact with the ground. The connector 208 facilitates connection and expansion with other components, enhancing the functionality of the placement box and enabling multi-specification centrifuge tube placement boxes to stably place centrifuge tubes of different specifications, control the temperature, and provide shock absorption protection.

[0045] When the solution inside the centrifuge tube needs to be stored in a low-temperature outdoor environment, the cooling controller 301 transmits a cooling control signal through the connecting line 302, which is then transmitted to multiple cooling plates 303. Upon receiving the power and control signals, the plates start working, generating a cooling effect and creating a cooling environment for the centrifuge tube. During the transmission of the cooling control signal through the connecting line 302, the battery 306 is isolated and protected by the partition 307. The battery 306 is powered. When the battery 306 is depleted, the expansion component 308 is used to deliver external power, ensuring that the cooling mechanism 3 can perform its cooling function normally.
