Liquid bagged sample temporary storage device

Abstract

This application provides a temporary storage device for liquid bagged samples. The storage box is box-shaped with an opening at the top. A slide rail is located at the top of the storage box. The sealing mechanism includes a male sealing rod and a female sealing rod slidably mounted on the slide rail. The male and female sealing rods can slide closer together to clamp the top opening of the liquid bag, or move away from each other to release the clamping force on the top opening of the liquid bag. A tightening mechanism is located between the corresponding male and female sealing rods. This application, through the cooperation of multiple sealing and locking mechanisms, utilizes the male and female sealing rods to clamp the top opening of the liquid bag, forming a uniform and tight clamping force at the bag opening. Because the sealing mechanism can slide along the slide rail, it can be flexibly adjusted according to the width of the liquid bag, ensuring that liquid bags of different sizes can be effectively sealed, avoiding gaps caused by incomplete sealing that allow contaminants to enter, greatly reducing the risk of sample contamination, and ensuring the accuracy of test results.

Description

Technical Field

[0001] This application belongs to the field of storage device technology, and more specifically, relates to a temporary storage device for liquid bagged samples. Background Technology

[0002] In the process of microbial testing, homogenizing bags are usually used to homogenize samples. The sample volume is usually relatively large, and liquid samples need to be temporarily stored and transferred during the pretreatment process.

[0003] Testing personnel typically use a binder clip to hold the folded and sealed homogenization bag in a food storage container to prevent the sample from tipping over and spilling, which could cause environmental pollution and sample damage. When the sample is reused, the clip is removed and the bag is reopened.

[0004] However, the clamping force of the dovetail clip is mainly concentrated at both ends and the middle of the clip, making it difficult to evenly compress the edge of the bag. This can easily leave gaps, allowing contaminants to enter the sample bag through the gaps and contaminate the sample. Utility Model Content

[0005] The purpose of this application is to provide a temporary storage device for liquid bagged samples to prevent sample contamination.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A temporary storage device for liquid bagged samples is provided, comprising a storage box, a slide rail, multiple sealing mechanisms, and multiple locking mechanisms. The storage box is box-shaped with an opening at the top. The slide rail is located at the top of the storage box. The sealing mechanism includes a male sealing rod and a female sealing rod slidably mounted on the slide rail. The male and female sealing rods can slide closer together to clamp the top opening of the liquid bag, or move away from each other to release the clamping force on the top opening of the liquid bag. Multiple locking mechanisms correspond one-to-one with the sealing mechanism, and are located between the corresponding male and female sealing rods. When the locking mechanism is engaged, the male sealing rod is fixed relative to the female sealing rod.

[0007] In one possible implementation, the slide rails include two rails, which are respectively disposed on the top of the opposite side walls of the storage box. The slide rails are T-shaped. The bottom of the male sealing rod and the female sealing rod are provided with sliding grooves, which are adapted to the slide rails, and the slide rails are inserted into the sliding grooves.

[0008] In one possible implementation, the male sealing rod has a pressing groove on its side wall facing the female sealing rod, and the female sealing rod has a pressing block on its side wall facing the male sealing rod. The pressing groove is semi-circular, and the pressing block is adapted to the pressing groove.

[0009] In one possible implementation, the locking mechanism includes a locking screw and a guide rod, wherein the locking screw is rotatably disposed at one end of the male sealing rod and is screwed onto the female sealing rod; the guide rod is fixed to the other end of the male sealing rod and is arranged through the female sealing rod.

[0010] In one possible implementation, the sealing rod is provided with a rotating hole, and the locking screw is provided with two spaced-apart limiting rings. The outer diameter of the limiting rings is larger than the inner diameter of the rotating hole. The locking screw is inserted into the rotating hole, and the limiting rings are located at both ends of the rotating hole.

[0011] In one possible implementation, a spring is provided between the male sealing rod and the female sealing rod, one end of the spring is fixed to the male sealing rod, the other end of the spring is fixed to the corresponding female sealing rod, and the spring is sleeved on the outside of the guide rod.

[0012] In one possible implementation, the female sealing rod is provided with an aperture groove, the aperture groove is annular, and the aperture groove is adapted to the limiting ring so that the limiting ring can be inserted into the aperture groove.

[0013] In one possible implementation, a transparent observation window is provided on the front side wall of the storage box.

[0014] In one possible implementation, the front sidewall of the storage box is provided with two spaced-apart mounting plates, and a roller is rotatably mounted between the mounting plates. A shielding curtain is wound on the roller, and the shielding curtain can be wound around the roller or unwound from the roller to block the observation window.

[0015] In one possible implementation, a portion of the viewing window is provided with Velcro, and another portion of the shielding curtain is provided with Velcro, so that the shielding curtain can be fixed relative to the viewing window by the Velcro.

[0016] The advantages of the temporary storage device for liquid bagged samples provided in this application are as follows: Compared with the prior art, this application uses multiple sealing mechanisms, with male and female sealing rods clamping the top opening of the liquid bag close to each other, to form a uniform and tight clamping force at the bag opening. Since the sealing mechanism can slide along the slide rail, it can be flexibly adjusted according to the width of the liquid bag, ensuring that liquid bags of different sizes can be effectively sealed, avoiding gaps caused by incomplete sealing that could allow contaminants to enter, greatly reducing the risk of sample contamination and ensuring the accuracy of test results.

[0017] Furthermore, traditional dovetail clips require manual clamping and releasing, which is cumbersome and prone to loss. In contrast, the sealing mechanism of this device uses sliding male and female sealing rods, resulting in simple and smooth operation without the need for additional tools. When processing large numbers of samples, testing personnel can quickly seal and open multiple liquid bags, significantly improving work efficiency and reducing time wastage and operational errors caused by frequent clamp operations.

[0018] The locking mechanism ensures the male sealing rod is fixed relative to the female sealing rod, preventing loosening of the sealing rod due to shaking, collisions, or other external forces during storage and transfer, thus ensuring the liquid bag remains in a good sealed state at all times. Unlike dovetail clips, which lose clamping force after repeated use and are easily damaged, the locking mechanism of this device can work stably for a long time, ensuring the reliability and service life of the device and providing a solid guarantee for the safe storage and transfer of samples.

[0027] The temporary storage device for liquid bagged samples provided in this application will now be described.

[0028] Please refer to the following: Figure 1 and Figure 5A temporary storage device for liquid bagged samples includes a storage box 1, a slide rail 2, multiple sealing mechanisms 3, and multiple locking mechanisms 4. The storage box 1 is box-shaped with an opening at the top. The slide rail 2 is located at the top of the storage box 1. The sealing mechanism 3 includes a male sealing rod 301 and a female sealing rod 302 slidably mounted on the slide rail 2. The male sealing rod 301 and the female sealing rod 302 can move closer to each other to clamp the top opening of the liquid bag, or move away from each other to release the clamping of the top opening of the liquid bag. The multiple locking mechanisms 4 correspond one-to-one with the sealing mechanism 3. The locking mechanism 4 is located between the corresponding male sealing rod 301 and female sealing rod 302. When the locking mechanism 4 is locked, the male sealing rod 301 is fixed relative to the female sealing rod 302.

[0029] The beneficial effects of the temporary liquid bag sample storage device provided in this embodiment are as follows: Compared with the prior art, the temporary liquid bag sample storage device provided in this embodiment uses multiple sealing mechanisms 3, with male sealing rod 301 and female sealing rod 302 clamping the top opening of the liquid bag close to each other, which can form a uniform and tight clamping force at the bag opening. Since the sealing mechanism 3 can slide along the slide rail 2, it can be flexibly adjusted according to the width of the liquid bag, ensuring that liquid bags of different sizes can be effectively sealed, avoiding the entry of contaminants due to gaps caused by poor sealing, greatly reducing the risk of sample contamination, and ensuring the accuracy of test results.

[0030] Furthermore, traditional dovetail clips require manual clamping and releasing, which is cumbersome and prone to loss. In contrast, the sealing mechanism of this device, with its sliding male sealing rod 301 and female sealing rod 302, offers simple and smooth operation without the need for additional tools. When processing large quantities of samples, testing personnel can quickly seal and open multiple liquid bags, significantly improving work efficiency and reducing time wastage and operational errors caused by frequent clamp operations.

[0031] The locking mechanism 4 secures the male sealing rod 301 relative to the female sealing rod 302, preventing the sealing rod from loosening due to shaking, collisions, or other external forces during storage and transfer, thus ensuring the liquid bag remains in a good sealed state. Unlike dovetail clips, which lose clamping force and are easily damaged after repeated use, the locking mechanism 4 of this device can work stably for a long time, ensuring the reliability and service life of the device and providing a solid guarantee for the safe storage and transfer of samples.

[0032] In this embodiment, the slide rail 2 includes two rails, which are respectively located on the top of the opposite side walls of the storage box 1. The slide rail 2 is T-shaped. The bottom of the male sealing rod 301 and the female sealing rod 302 are provided with sliding grooves, which are adapted to the slide rail 2. The slide rail 2 is inserted into the sliding groove.

[0033] The T-shaped slide rail 2 and the groove's matching design effectively limit the displacement of the male sealing rod 301 and female sealing rod 302 in the direction perpendicular to the sliding direction during sliding, reducing shaking and jamming. Compared to the ordinary slide rail 2 structure, this design allows the sealing rod to move more smoothly along the slide rail 2, ensuring accuracy and consistency when clamping the liquid bag, avoiding sealing problems caused by poor sliding, and further improving the sealing effect and user experience of the device. Two slide rails 2 are respectively located on the top of opposite side walls of the storage tank 1, providing a stable support structure for the male sealing rod 301 and the female sealing rod 302. When clamping the liquid bag, the reaction force on the sealing rod can be evenly distributed to the side wall of the storage tank 1 through the slide rails 2, enhancing the overall structural strength and stability of the device.

[0034] like Figure 3 As shown, the male sealing rod 301 has a pressing groove 303 on its side wall facing the female sealing rod 302, and the female sealing rod 302 has a pressing block 304 on its side wall facing the male sealing rod 301. The pressing groove 303 is semi-circular, and the pressing block 304 is adapted to the pressing groove 303.

[0035] The semi-circular clamping groove 303 and the clamping block 304 are mutually compatible. When the male sealing rod 301 and the female sealing rod 302 clamp the liquid bag, the clamping block 304 can be embedded into the clamping groove 303 to form a tight fit. This structure can generate a larger contact area and a more uniform pressure distribution at the top opening of the liquid bag. Compared with ordinary planar contact clamping methods, it can more effectively eliminate gaps and prevent contaminants from entering.

[0036] In this embodiment, the locking mechanism 4 includes a locking screw 401 and a guide rod 402. The locking screw 401 is rotatably disposed at one end of the male sealing rod 301 and screwed onto the female sealing rod 302. The guide rod 402 is fixed at the other end of the sealing rod and passes through the female sealing rod 302.

[0037] The locking screw 401 is screwed onto the female sealing rod 302. Rotating the screw precisely controls the clamping force between the male and female sealing rods 301 and 302. Unlike the clamping force of a dovetail clamp, this device can flexibly adjust the clamping degree according to the material and thickness of the liquid bag, ensuring a good seal without damaging the liquid bag due to excessive clamping force. The guide rod 402 provides stable guidance for the screw's rotation, preventing deviation or wobbling during rotation, ensuring the accuracy and reliability of the locking operation, and maintaining a stable relative position between the male and female sealing rods 301 and 302 after locking. The combined structure of the locking screw 401 and guide rod 402 offers higher structural strength and stability compared to simple snap-fit ​​or spring-loaded locking methods. It is less prone to loosening or damage during long-term use and frequent operation. Even under significant external impact, the guide rod 402 effectively restricts the displacement of the sealing rod, while the locking screw 401 remains locked, ensuring the sealing effect of the liquid bag remains unaffected and improving the reliability and durability of the device in complex operating environments.

[0038] Combination Figure 2 and Figure 5 As shown, the sealing rod 301 is provided with a rotating hole, and the locking screw 401 is provided with two spaced limiting rings 403. The outer diameter of the limiting rings 403 is larger than that of the rotating hole. The locking screw 401 is inserted into the rotating hole, and the limiting rings 403 are located at both ends of the rotating hole.

[0039] The outer diameter of the limiting ring 403 is larger than that of the rotating hole, effectively preventing the screw from dislodging from the rotating hole. During frequent screw rotation for tightening and loosening operations, this design ensures the screw remains connected to the male sealing rod 301, preventing the device from malfunctioning due to screw detachment. Compared to screw connections without a limiting structure, this significantly improves the reliability and stability of the device and reduces maintenance and replacement costs caused by component detachment. like Figure 3 As shown, a spring 404 is provided between the male sealing rod 301 and the female sealing rod 302. One end of the spring 404 is fixed on the male sealing rod 301, and the other end of the spring 404 is fixed on the corresponding female sealing rod 302. The spring 404 is sleeved on the outside of the guide rod 402.

[0040] The spring 404 is designed so that when the locking screw 401 is rotated and the male sealing rod 301 and female sealing rod 302 move away from each other, the spring 404 can release energy and push the ends of the male sealing rod 301 and female sealing rod 302 with guide rods 402 away from each other. This prevents the male sealing rod 301 and female sealing rod 302 from having a circumferential angle due to only having a locking screw 401 at one end, and makes the moving away of the male sealing rod 301 and female sealing rod 302 smoother.

[0041] like Figure 5 As shown, the female sealing rod 302 is provided with a relief groove 305. The relief groove 305 is annular and is adapted to the limiting ring 403 so that the limiting ring 403 can be inserted into the relief groove 305.

[0042] The clearance groove 305 is adapted to the limiting ring 403, allowing the limiting ring 403 to be inserted into the clearance groove 305. When adjusting the clamping force by rotating the locking screw 401, the limiting ring 403 can move within the clearance groove 305, preventing interference between the limiting ring 403 and the side wall of the female sealing rod 302, thus ensuring smooth screw rotation. This design optimizes the user experience of the locking mechanism 4. Inspectors no longer need to worry about the limiting ring 403 obstructing screw rotation, enabling them to complete clamping and loosening operations more easily and quickly, improving work efficiency. The clearance groove 305 allows the limiting ring 403 to embed into the female sealing rod 302, effectively reducing the overall size of the male sealing rod 301 and the female sealing rod 302 in the locked state, making the device structure more compact. It also allows the opposing surfaces of the male sealing rod 301 and the female sealing rod 302 to abut against each other, thus facilitating a greater clamping force on the liquid bag.

[0043] like Figure 1 As shown, a transparent observation window 101 is provided on the front side wall of the storage box 1.

[0044] The transparent observation window 101 allows testing personnel to directly observe the state of the liquid inside the storage box 1 without opening it, including whether there is any leakage or color change. In microbial testing, timely understanding of the sample's condition is crucial for ensuring the accuracy of test results. Through the observation window 101, testing personnel can monitor the sample at any time, and take swift action upon detecting any abnormalities, avoiding test failures or erroneous results due to delayed problem detection, thus improving the reliability and efficiency of the testing work. When it is necessary to locate a specific sample or confirm the sample quantity, the testing personnel can quickly locate it through the observation window 101 without having to open the liquid bags in the storage box 1 one by one, saving time and effort. For the storage and management of large numbers of samples, the presence of the observation window 101 can significantly improve the ease of operation, making the work of the testing personnel more efficient and convenient, and reducing the risk of sample contamination and time costs caused by frequent opening of the box.

[0045] like Figure 4 As shown, two mounting plates 102 are arranged at intervals on the front side wall of the storage box 1. A roller 103 is rotatably mounted between the mounting plates 102. A shielding curtain 104 is wound on the roller 103. The shielding curtain 104 can be wound on the roller 103 due to the rotation of the roller 103, or unwound from the roller 103 to block the observation window 101.

[0046] In some microbial testing experiments, samples may be sensitive to light. Prolonged exposure to light can affect sample properties and lead to inaccurate test results. The shielding curtain 104 can be wound or unfolded by rotating the roller 103. When sample protection is needed, the shielding curtain 104 can be unfolded to block the observation window 101, effectively preventing light from reaching the sample inside the storage box 1 and avoiding adverse effects from light. This design provides excellent protection for light-sensitive samples, ensuring sample stability during storage and improving the reliability of test results.

[0047] Here, if you want to completely shield the liquid bag from light, you can also cover the top of the storage tank with a shield to block the light from above.

[0048] The shielding curtain 104 can be unfolded or retracted at any time according to actual needs, which is more flexible than a fixed light-blocking structure. When the inspector needs to observe the sample, the shielding curtain 104 can be easily wrapped around the roller 103, exposing the observation window 101; after observation, the curtain can be unfolded to block the light. This flexible adjustment method can adapt to different inspection needs and operating scenarios, ensuring the safety of the sample without affecting the inspector's observation and operation of the sample, thus improving the practicality and applicability of the device.

[0049] In this embodiment, the roller 103 extends to the outside of the left-side mounting plate 102. A torsion spring is provided between the portion of the roller 103 extending to the outside of the mounting plate 102 and the corresponding side of the mounting plate 102. When the torsion spring is in its natural state, the curtain 104 is completely wrapped around the roller 103. The torsion spring facilitates the automatic winding of the curtain 104. In addition, a protective box is fixed to the mounting plate 102 to cover and protect the torsion spring and the end of the roller 103.

[0050] Finally, the viewing window 101 is provided with a portion of the Velcro 105, and the curtain 104 is provided with the other portion of the Velcro 105, so that the curtain 104 can be fixed relative to the viewing window 101 by the Velcro 105.

[0051] The Velcro 105 allows the shielding curtain 104 to be securely fixed to the observation window 101. Compared to simple hooks or clips, the Velcro 105 has a larger contact area and stronger adhesive force, effectively preventing the shielding curtain 104 from falling off during use. During storage and transfer, even if the device is subjected to vibration or minor impact, the Velcro 105 maintains the stability of the shielding curtain 104, ensuring its continued light-blocking function and providing reliable protection for the sample. Furthermore, the Velcro 105's fixing method is simple to operate; inspectors can easily attach or remove the curtain, making it convenient and quick.

[0052] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
