Description

Technical Field

[0001] This utility model relates to the field of biological product sample storage technology, and in particular to a biological product sample storage box. Background Technology

[0002] Biological sample storage boxes are key equipment in biomedicine, vaccine transportation, and laboratory research. They are mainly used to preserve temperature- and vibration-sensitive samples, such as cell cultures, blood products, and viral vectors. With the rapid development of biotechnology, the demand for sample transportation and storage is increasing, placing higher demands on the safety, convenience, and stability of storage boxes. Especially in emergency medical care and sample collection scenarios in remote areas, the ability to quickly access samples directly affects the timeliness of subsequent testing and treatment. Therefore, designing a storage box that combines efficient loading and unloading with shockproof protection has become an urgent need in the industry to meet the high standards of modern biological sample management.

[0003] Most existing biological sample storage boxes use fixed partitions or bolt-fastened structures, with sample racks secured to the box body by mechanical latches or screws. Their technical principle relies on physical constraints to achieve stable sample storage. Although some boxes are equipped with simple shock-absorbing materials, the shock absorption mechanism is simplistic, relying solely on static filling to absorb vibrations and lacking dynamic buffering design. In addition, loading and unloading samples requires manually loosening screws or disassembling multiple sets of latches, making the operation cumbersome. Furthermore, some structures are prone to thread wear or latch failure due to long-term use, further reducing reliability.

[0004] The main problem with existing technologies is the low efficiency of fixing plate disassembly, which leads to time-consuming and labor-intensive sample storage and retrieval. The fixing plates of traditional storage boxes usually rely on screws or complex locking mechanisms for fixation. Tools or repeated operation of the latches are required during loading and unloading, which not only prolongs the sample loading and unloading time, but also damages the box structure due to improper operation. In emergency situations, this inefficient disassembly method seriously slows down the work progress and may even affect the sample viability. Therefore, a structural solution that can quickly disassemble the fixing plate is needed to improve the practicality and emergency response capability of the storage box. To this end, a biological product sample storage box is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a biological product sample storage box, which aims to improve the problem of low sample storage and retrieval efficiency caused by the cumbersome disassembly of the fixing plate in the existing traditional storage box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a biological product sample storage box, including a box body, a box cover provided on the top of the box body, a fixed plate slidably connected inside the box body, a handle fixedly connected to the top of the fixed plate, and a quick-release assembly provided inside the fixed plate;

[0007] The quick-release assembly includes a sliding ring, a pull rod, and a locking pin. The outer wall of the sliding ring is slidably connected to the inside of the fixed plate. One end of the pull rod is fixedly connected to the outer wall of the sliding ring, and the outer wall of the pull rod is slidably connected to the inside of the fixed plate. One end of the locking pin is fixedly connected to the outer wall of the sliding ring, and the outer wall of the locking pin is slidably connected to the inside of the fixed plate. The outer wall of the locking pin is slidably connected to the inside of the housing. A locking hole is provided inside the housing, and the locking pin and the locking hole engage. A spring is provided inside the fixed plate, and a shock-absorbing assembly is provided inside the housing.

[0008] As a further description of the above technical solution:

[0009] One end of the spring is fixedly connected inside the fixed plate, and the other end of the spring is fixedly connected to the outer wall of the sliding ring.

[0010] As a further description of the above technical solution:

[0011] The shock absorption assembly includes a connecting block and a sliding block. The top of the connecting block is in contact with the bottom of the fixing plate, and the top of the sliding block is fixedly connected to the bottom of the connecting block.

[0012] As a further description of the above technical solution:

[0013] A hollow block is slidably connected to the outer wall of the sliding block, and a bottom block is fixedly connected to the bottom of the hollow block.

[0014] As a further description of the above technical solution:

[0016] As a further description of the above technical solution:

[0017] A damper is installed inside the hollow block. The bottom of the damper is fixedly connected to the top of the base block, and the output end of the damper is fixedly connected to the bottom of the connecting block.

[0018] As a further description of the above technical solution:

[0019] A second spring is provided on the outer wall of the damper. One end of the second spring is fixedly connected to the bottom of the connecting block, and the other end of the second spring is fixedly connected to the top of the bottom block.

[0020] As a further description of the above technical solution:

[0021] A sponge block 1 is fixedly connected inside the fixing plate, and a sponge block 2 is fixedly connected inside the box cover.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by pulling the pull rod, the sliding ring and the locking post are moved into the fixed plate. At the same time, the spring is squeezed to make the locking post disengage from the locking hole. Then, by pulling the handle, the fixed plate can be quickly removed, thereby achieving the effect of quick loading and unloading of samples. This solves the problem of low sample storage and retrieval efficiency caused by the cumbersome disassembly of the fixed plate in traditional storage boxes, and improves the convenience of use and emergency handling capability of the storage box.

[0024] 2. In this utility model, the sample is buffered and protected by sponge block one and sponge block two. When the sample is hit by an external impact during transportation, the damper and spring two work together to quickly absorb and attenuate the impact force, thereby achieving the effect of effectively protecting biological product samples. This solves the problem that traditional storage boxes are prone to damage from vibration during transportation due to the lack of effective shock absorption measures, and improves the shockproof performance of the storage box and the safety of sample preservation.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] Reference Figures 1-3 The present invention provides an embodiment of a biological product sample storage box, comprising a box body 1, a box cover 2 provided on the top of the box body 1 for sealing the internal space of the box body 1 to prevent external contamination and maintain a stable storage environment, a fixing plate 3 slidably connected inside the box body 1 for supporting and fixing the biological product samples to keep them stable during transportation, a handle 5 fixedly connected to the top of the fixing plate 3 for easy gripping and pulling of the fixing plate 3 for loading and unloading operations, and a quick-release assembly provided inside the fixing plate 3 for quick installation and removal of the fixing plate 3;

[0035] The quick-release assembly includes a sliding ring 6, a pull rod 7, and a locking post 8. The outer wall of the sliding ring 6 is slidably connected to the inside of the fixed plate 3, allowing the sliding ring 6 to move along the inner wall of the fixed plate 3. One end of the pull rod 7 is fixedly connected to the outer wall of the sliding ring 6 for manually pulling the sliding ring 6 to slide. The outer wall of the pull rod 7 is slidably connected to the inside of the fixed plate 3 to ensure the stability of the pull rod 7 during movement. One end of the locking post 8 is fixedly connected to the outer wall of the sliding ring 6, allowing the locking post 8 to move synchronously with the sliding ring 6. The outer wall of the locking post 8 is slidably connected to the inside of the fixed plate 3, and simultaneously slidably connected to the inside of the housing 1, allowing the locking post 8 to slide between the fixed plate 3 and the housing 1. The housing 1 has an opening inside... The locking hole 10 and the locking post 8 engage with each other to lock the position of the fixing plate 3 and prevent it from slipping out accidentally. A spring 9 is installed inside the fixing plate 3. One end of the spring 9 is fixedly connected to the inside of the fixing plate 3, and the other end is fixedly connected to the outer wall of the sliding ring 6. It is used to automatically reset the sliding ring 6 after the locking post 8 is disengaged from the locking hole 10, ensuring the reusability of the quick-release assembly. The box 1 is equipped with a shock-absorbing assembly to absorb the impact and vibration during transportation and protect the biological product samples from damage. The function of the spring 9 also includes pushing the sliding ring 6 back to its original position after the pull rod 7 is released, so that the locking post 8 can be re-engaged into the locking hole 10, completing the quick fixation of the fixing plate 3.

[0036] Reference Figures 4-6The shock-absorbing assembly includes a connecting block 13 and a sliding block 14. The top of the connecting block 13 contacts the bottom of the fixed plate 3, transmitting the impact force received by the fixed plate 3 to the shock-absorbing structure. The top of the sliding block 14 is fixedly connected to the bottom of the connecting block 13, allowing the sliding block 14 to move synchronously with the connecting block 13. A hollow block 11 is slidably connected to the outer wall of the sliding block 14, providing a sliding guide function to ensure stable vertical movement of the shock-absorbing assembly. A bottom block 12 is fixedly connected to the bottom of the hollow block 11, and the bottom of the bottom block 12 is fixedly connected inside the housing 1, forming a stable support structure. A rubber pad 18 is fixedly connected to the bottom of the housing 1 to absorb vibrations between the housing 1 and the placement surface. A damper 15 is installed inside the hollow block 11. The bottom of the damper 15 is fixedly connected to the top of the base block 12, and the output end of the damper 15 is fixedly connected to the bottom of the connecting block 13. It dissipates impact energy through damping. A second spring 16 is installed on the outer wall of the damper 15. One end of the second spring 16 is fixedly connected to the bottom of the connecting block 13, and the other end is fixedly connected to the top of the base block 12. It works in conjunction with the damper 15 to provide elastic buffering. A first sponge block 4 is fixedly connected inside the fixed plate 3 to directly buffer and protect the sample placed on the fixed plate 3. A second sponge block 17 is fixedly connected inside the box cover 2 to apply flexible limiting and protection to the top of the sample when the box cover 2 is closed.

[0037] Working principle: When a sample needs to be removed, pulling the lever 7 causes the sliding ring 6 to slide inside the fixed plate 3, simultaneously compressing the spring 9. The movement of the sliding ring 6 causes the locking post 8, which is fixedly connected to it, to move synchronously, thereby disengaging the locking post 8 from the locking hole 10 of the housing 1 and releasing the restriction on the fixed plate 3. At this time, the fixed plate 3 can be easily pulled out of the housing 1 using the handle 5. When the fixed plate 3 needs to be reinstalled, simply push the fixed plate 3 into the housing 1 to the set position, release the lever 7, and the restoring force of the spring 9 pushes the sliding ring 6 to reset, causing the locking post 8 to re-lock into the locking hole 10, completing the fixation, thus achieving the purpose of quick sample loading and unloading. When protecting the sample, the sponge block 4 and the sponge block 17 directly wrap the sample, absorbing minor vibrations through the elasticity of the material itself. When encountering a larger impact, the impact force is transmitted through the fixed plate 3 to the connecting block 13, which in turn pushes the sliding block 14 to slide inside the hollow block 11. At this time, spring 16 is compressed and absorbs energy through elastic deformation; at the same time, damper 15 further reduces impact energy, and rubber pad 18 at the bottom of box 1 can isolate vibration transmission from the external environment, thereby achieving the purpose of effectively protecting biological product samples.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
