Description

Technical Field

[0001] This utility model relates to the field of rapid sealing technology for medical reagent transport boxes, and in particular to a rapid sealing locking device for medical reagent transport boxes. Background Technology

[0002] In the pharmaceutical industry, the safety and stability of reagent transportation are paramount. Pharmaceutical reagents are often highly active, perishable, and some even pose biological hazards, thus requiring extremely high levels of sealing and shock resistance during transport. The quick-sealing locking device of the pharmaceutical reagent transport box, as a core component ensuring reagent safety, directly impacts the quality of transportation.

[0003] Currently, the locking devices of common medical reagent transport boxes are relatively simple in structure. Many use a simple plastic buckle design, which uses a simple hook to engage with a slot on the box body, utilizing the elasticity of the plastic itself to achieve a lock. When the lid is closed, the hook of the buckle engages with the slot, and the rebound force generated by the slight deformation of the plastic maintains the locked state; to unlock, the buckle can be manually pried open.

[0004] However, these simple locking devices pose serious safety hazards. During the transportation of pharmaceutical reagents, especially after long-distance bumpy rides or multiple handling, the transport box is continuously subjected to high-frequency vibrations. Because existing locking devices lack necessary limiting and anti-loosening structures, the buckles and slots are prone to misalignment under high-frequency vibrations. Once misaligned, the simple plastic buckles, due to insufficient material toughness, are easily fatigued and break during vibration, causing the lock to loosen and eventually pop open automatically. After the lock pops open, the lid becomes loose, and the internal reagents are directly exposed to the external environment. For biological agents and vaccines that are sensitive to temperature, humidity, and air, this can lead to a rapid decrease in their activity; liquid reagents may leak due to shaking, not only causing significant waste but also contaminating other goods. If hazardous biological reagents are involved, it could even trigger a serious biosafety incident, posing a great risk and loss to pharmaceutical transportation. Therefore, a quick-sealing locking device for pharmaceutical reagent transport boxes is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick-sealing locking device for a medical reagent transport box, which aims to improve the problem of automatic pop-out of the lock in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-sealing locking device for a medical reagent transport box includes a housing, a limiting component provided on the outer wall of the housing, a box cover provided on the top of the housing, and a locking component provided on the outer wall of the box cover;

[0008] The limiting component includes a limiting plate, the outer wall of which is disposed on the outer wall of the outer shell. A sliding groove is formed inside the outer shell. A fixing frame is fixedly connected to the outer wall of the outer shell. A fixing post is fixedly connected to the outer wall of the fixing frame. A sliding post is slidably connected to the inner wall of the fixing post. A spring is disposed inside the fixing post.

The bottom of the limiting plate is fixedly connected to the top of the sliding post. A sliding rod is fixedly connected to the outer wall of the limiting plate. The outer wall of the sliding rod is slidably connected to the inner wall of the sliding groove.

[0009] As a further description of the above technical solution:

[0010] The locking assembly includes a buckle, the outer wall of which is fixedly connected to the outer wall of the box cover, and a fixing plate is fixedly connected to the outer wall of the outer shell;

[0011] As a further description of the above technical solution:

[0012] A limit post is fixedly connected to the outer wall of the fixing plate, and a fixing block is fixedly connected to the outer wall of the fixing plate;

[0013] As a further description of the above technical solution:

[0014] A rotating column is rotatably connected to the outer wall of the fixed block, and a toggle block is fixedly connected to the outer wall of the rotating column;

[0015] As a further description of the above technical solution:

[0016] The outer wall of the actuating block is in contact with the outer wall of the limiting post, and a rotating rod is rotatably connected to the inner wall of the actuating block;

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the sliding rod is moved by the limiting plate, and then the moving rod moves inside the sliding groove, which achieves the effect of limiting the toggle block. This avoids the high-frequency vibration during transportation causing the block and buckle to misalign, resulting in the block automatically popping open, the box lid becoming loose and the seal failing. This also prevents the reagent from coming into contact with the outside air due to shaking, or the liquid reagent from leaking out. This enhances the reliability of the seal, increases the vibration resistance level, and avoids the risk of leakage.

[0023] 2. In this utility model, the rotating rod is moved by the actuating block, and then the connecting block is moved by the rotating rod, which achieves the effect of locking the lid. This avoids the traditional transport box from automatically popping open when subjected to severe vibration or external impact, which would cause the lid to loosen, the seal to fail, reagents to leak and contaminate other goods, or outside air to enter the box. This improves the reliability of the seal and ensures the safety of reagent transportation. Attached Figure Description

[0032] 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.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a quick-sealing locking device for a medical reagent transport box, comprising a shell 1, a limiting component on the outer wall of the shell 1, a lid 2 on the top of the shell 1, and a locking component on the outer wall of the lid 2. The limiting component includes a limiting plate 7, which limits the displacement of the actuating block 14 during transport, enhancing the stability of the locking and preventing the lid 2 from loosening. The outer wall of the limiting plate 7 is disposed on the outer wall of the shell 1. A sliding groove 9 is provided inside the shell 1. A fixing frame 3 is fixedly connected to the outer wall of the shell 1. A fixing post 4 is fixedly connected to the outer wall of the fixing frame 3. A sliding post 5 is slidably connected to the inner wall of the fixing post 4. An internal spring 6 is installed, with one end of the spring 6 fixedly connected to the inner wall of the fixed column 4 and the other end fixedly connected to the bottom of the sliding column 5. Through the elasticity of the spring 6, the limiting plate 7 is always located on the outer wall of the actuating block 14, preventing the actuating block 14 from shaking during transportation. The bottom of the limiting plate 7 is fixedly connected to the top of the sliding column 5, and a sliding rod 8 is fixedly connected to the outer wall of the limiting plate 7. The outer wall of the sliding rod 8 is slidably connected to the inner wall of the sliding groove 9. The sliding rod 8 and the sliding groove 9 work together to achieve a linear motion effect, preventing the limiting plate 7 from shifting during transportation, which would prevent the actuating block 14 from being unable to be limited, thus increasing the stability during transportation.

[0034] Reference Figure 1 and Figures 4-6The locking assembly includes a buckle 19, the outer wall of which is fixedly connected to the outer wall of the lid 2. A fixing plate 10 is fixedly connected to the outer wall of the outer shell 1. A limit post 11 is fixedly connected to the outer wall of the fixing plate 10. The limit post 11 is used to limit the rotation angle of the actuating block 14, preventing excessive rotation of the actuating block 14 from causing the lid 2 to fail to close tightly, thus preventing the lid 2 from failing to seal and increasing its stability. A fixing block 12 is fixedly connected to the outer wall of the fixing plate 10. A rotating post 13 is rotatably connected to the outer wall of the fixing block 12. An actuating block 14 is fixedly connected to the outer wall of the rotating post 13. The outer wall of the actuating block 14 is in contact with the outer wall of the limit post 11. A rotating rod 15 is rotatably connected to the inner wall of the actuating block 14. A connecting block is fixedly connected to the outer wall of the rotating rod 15. 16. When the operator moves the actuating block 14, the actuating block 14 rotates in conjunction with the rotating column 13, which then moves the rotating rod 15. The rotating rod 15 then moves the connecting block 16, thus converting the operator's manual operation into rotational power. The connecting block 16 is fixedly connected to the outer wall of the connecting column 17, and the connecting column 17 is fixedly connected to the outer wall of the locking block 18. The outer wall of the locking block 18 engages with the buckle 19. When the actuating block 14 rotates, the rotating rod 15 drives the connecting block 16, the connecting column 17, and the locking block 18 to move in tandem, which then causes the buckle 19 to engage with the locking block 18, thereby increasing the stability during transportation and achieving a quick and secure locking of the box cover 2.

[0035] Working principle: When limiting the actuating block 14, firstly, the limiting plate 7 is pulled down, which drives the sliding rod 8 to move inside the sliding groove 9. Then, the limiting plate 7 drives the sliding column 5 to move, which in turn compresses the spring 6. After the actuating block 14 is installed in place, the limiting plate 7 is released. Then, the spring 6 rebounds and drives the rotating rod 15 to reset. Then, the reset of the sliding column 5 drives the limiting plate 7 to move. Finally, when the outer wall of the limiting plate 7 contacts the outer wall of the actuating block 14, the actuating block 14 is limited. This prevents the high-frequency vibration during transportation from causing the locking block 18 and the buckle 19 to misalign, which would cause the locking block 18 to pop open automatically. If the box cover 2 becomes loose, the seal will fail, and the reagent will come into contact with the outside air due to shaking, or the liquid reagent may leak.

[0036] When locking the lid 2, first, the actuating block 14 is moved, which moves the rotating rod 15. Then, the rotating rod 15 moves the connecting block 16, which in turn moves the connecting post 17. The connecting post 17 then moves the locking block 18, and the lid 2 is closed. Next, the actuating block 14 is moved in the opposite direction, which moves the rotating rod 15. Then, the rotating rod 15 moves the connecting block 16, which in turn moves the connecting post 17. The connecting post 17 then moves the locking block 18, and the locking block 18 and the buckle 19 engage to lock the lid 2. This prevents the traditional transport box from automatically opening when subjected to severe vibration or external impact, which could cause the lid 2 to loosen, lose its seal, leak reagents and contaminate other goods, or allow outside air to enter the box.

[0037] 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.
