Description

Technical Field

[0001] This utility model relates to the field of cold chain logistics equipment technology, and in particular to a portable low-temperature refrigerated transport box for biomedical reagents. Background Technology

[0002] Biopharmaceutical reagents, such as vaccines, diagnostic reagents, and biopharmaceuticals, are typically highly temperature-sensitive; their chemical composition and biological activity are easily altered or even rendered ineffective at room temperature. Therefore, it is essential to ensure that these reagents are always kept in a stable and controlled low-temperature environment during storage, transportation, and use. To meet this requirement, various types of portable low-temperature refrigerated transport boxes are widely used in medical institutions, laboratories, and pharmaceutical distribution.

[0003] Currently, commercially available portable transport cases typically employ a passive refrigeration solution combining an insulated enclosure with a cold storage agent (such as ice packs or phase change materials) to provide a low-temperature environment. However, those skilled in the art have observed through long-term practice that while existing products can meet basic insulation and refrigeration requirements, they still have significant shortcomings in terms of ease of operation and structural reliability. Particularly concerning is the design of the locking mechanism; many transport cases still utilize traditional snap-lock, rotary lock, or multi-point latch designs. In fast-paced work environments requiring frequent reagent handling, such as emergency situations or high-throughput laboratories, operators often need to use both hands to manually unlock or fasten these latches one by one, a cumbersome and time-consuming process that significantly reduces work efficiency. Furthermore, these traditional latch structures are prone to wear, loosening, or even accidental pop-out during repeated use or transport. If the lid is not properly sealed, it will directly lead to cold loss and an increase in internal temperature, potentially causing irreversible damage to valuable biological reagents. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable low-temperature refrigerated transport box for biomedical reagents, which aims to improve the problems of cumbersome operation of the locking mechanism, low opening efficiency, easy accidental loosening during transportation, and insufficient structural reliability of the portable low-temperature refrigerated transport box for biomedical reagents.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable low-temperature refrigerated transport box for biomedical reagents, including a lid, a box body, a rotating shaft, a heat preservation mechanism, and a quick-release mechanism with an improved structure.

[0006] The quick-release mechanism includes a buckle on the housing, a first connecting block, a second connecting block, a pull rod, a crossbar at the end of the pull rod, a first limiting block and a second limiting block with built-in sliding groove, and a spring.

[0007] Furthermore, the lid is provided with a protrusion for pressing the first connecting block and the second connecting block; the first connecting block and the second connecting block are tractively connected to the pull rod; both ends of the crossbar are slidably received in the grooves of the first limiting block and the second limiting block to move between the locked position and the unlocked position; the spring stores energy when the second connecting block is compressed; the crossbar limits the buckle in the locked position to prevent it from opening.

[0008] Preferably, the insulation mechanism includes an insulation layer disposed within the box wall, a sealing ring disposed at the junction of the box cover and the box body, and a refrigeration component detachably disposed within the box body; the refrigeration component includes a refrigeration box and a base for fixing the refrigeration box.

[0009] Preferably, the inner wall of the housing is provided with a groove for sliding installation of a partition, which is used to divide the internal space of the housing and to position the refrigeration components.

[0010] Preferably, the quick-release mechanism further includes a first protective shell and a second protective shell; the second protective shell covers and fixes the first connecting block, the second connecting block, the pull rod, the first limiting block, the second limiting block, and the spring; the first protective shell is located on the outside of the buckle and is used to limit and support it when the buckle is opened.

[0011] Preferably, both the first connecting block and the second connecting block are fixedly connected to the pull rod so that the pull rod can be driven to move axially synchronously when pressed by the groove.

[0012] Preferably, the main body of the crossbar is arranged perpendicular to the axial direction of the pull rod, and its two ends extend into the grooves of the first limiting block and the second limiting block, respectively.

[0013] Preferably, the spring is a compression spring, which is disposed between the second connecting block and the inner wall of the second protective shell, and is used to provide a restoring force to the second connecting block after the pressure of the groove is released.

[0014] Preferably, the upper end of the buckle is provided with an inwardly bent hook, and the side wall of the box cover is provided with a snap-fit ​​edge that cooperates with the hook. The buckle is locked by snapping its hook with the snap-fit ​​edge.

[0015] This utility model has the following beneficial effects: 1. In this utility model, a quick-release mechanism is set up by linking components such as connecting blocks, pull rods, crossbars, and limiting blocks with built-in sliding grooves. The pressing action of the box lid realizes the sliding of the crossbar in the sliding groove of the limiting block, thereby controlling the locking and unlocking of the buckle. This solves the problems of cumbersome operation and low opening efficiency of the locking mechanism of the transport box in the prior art. It achieves the effect of quick pressing to unlock and press to lock with one hand, which greatly improves the convenience of operation and work efficiency of medical or laboratory personnel when frequently picking up and putting down reagents.

[0016] 2. In this utility model, the crossbar forms a stable physical limit on the buckle when it is in the locked position, and a first protective shell is set to support and limit it when the buckle is opened. This solves the problem that the traditional buckle structure may be accidentally loosened due to vibration or that the components may be fatigued and broken due to repeated use. It achieves an extremely stable locking state and effectively prevents accidental opening during transportation. At the same time, it improves the structural strength and service life of the quick-release mechanism and enhances the overall reliability. Attached Figure Description

[0019] 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.

[0020] Please refer to Figures 1 to 5 This utility model provides a portable low-temperature refrigerated transport box for biomedical reagents, which aims to solve the problems of cumbersome operation, low efficiency and insufficient closure reliability of the locking mechanism of existing biological reagent transport boxes when reagents are frequently retrieved.

[0021] like Figure 1 As shown, the portable biomedical reagent low-temperature refrigerated transport box includes a lid 1 and a box body 2. The lid 1 is rotatably connected to the box body 2 via a pivot 3 to realize the opening and closing of the lid 1. The box body 2 is equipped with an insulation mechanism 4 inside, and a quick-release mechanism 5 for locking the lid 1 and the box body 2 is also installed on the box body 2.

[0022] Specifically, please refer to Figure 4 and Figure 5 The quick-release mechanism 5 includes a buckle 5010, a first protective shell 501, a second protective shell 502, a first connecting block 503, a second connecting block 507, a pull rod 504, a crossbar 505, a first limiting block 506, a second limiting block 508, and a spring 509. The bottom of the cover 1 has a groove fixedly connected to the position of the first connecting block 503 and the second connecting block 507. Both the first connecting block 503 and the second connecting block 507 are fixedly connected to one end of the pull rod 504. The crossbar 505 is fixedly connected to the other end of the pull rod 504 away from the first connecting block 503 and the second connecting block 507, and the main body direction of the crossbar 505 is perpendicular to the axial direction of the pull rod 504. The first limiting block 5010... Both the 6th and second limiting blocks 508 have internal grooves for the sliding passage of the two ends of the crossbar 505. The spring 509 is a compression spring, which is sleeved on or abuts against the second connecting block 507. The entire internal assembly of the quick-release mechanism 5 is covered by the second protective shell 502 and fixed to the outer wall of the housing 2. The buckle 5010 is pivotally connected to the quick-release mechanism 5. When the crossbar 505 is in the locked position, its body abuts against and limits the buckle 5010, preventing the buckle 5010 from rotating and opening. The first protective shell 501 is fixedly connected to the second protective shell 502 and is located outside the movement path of the buckle 5010 when it opens, serving to limit and support the opened buckle 5010 and prevent it from opening excessively and being damaged. As a preferred embodiment, refer to Figure 2 and Figure 3The insulation mechanism 4 includes an insulation layer 403 fixedly installed inside the wall of the box body 2 and a sealing ring 406 installed at the junction of the box cover 1 and the box body 2. A groove 401 is provided on the inner wall of the box body 2. The insulation mechanism 4 also includes a partition 402 that can be slidably installed along the groove 401. The bottom of the partition 402 is fixedly connected to a base 404 for placing the refrigeration box 405.

[0023] As another preferred embodiment, refer to Figure 4 and Figure 5 The structure of the quick-release mechanism 5 is further defined. The second protective shell 502 covers and fixes the internal components of the quick-release mechanism 5. The first protective shell 501 is located outside the buckle 5010. The first connecting block 503 and the second connecting block 507 are both fixedly connected to the pull rod 504. The crossbar 505 is vertically fixedly connected to the other end of the pull rod 504. Its two ends extend into the sliding grooves of the first limiting block 506 and the second limiting block 508, respectively. The spring 509 is a compression spring and is located between the second connecting block 507 and the inner wall of the second protective shell 502. The upper end of the buckle 5010 is bent to form a hook. The side wall of the box cover 1 is provided with a corresponding snapping edge that cooperates with the hook.

[0024] The insulation layer 403 is filled inside the wall of the box 2 to block the entry of external heat. The sealing ring 406 is installed at the joint between the box cover 1 and the box 2 to enhance airtightness and reduce cold loss. The refrigeration box 405 is filled with refrigerant as a cold source and is placed by the base 404. The groove 401 on the inner wall of the box 2 provides a sliding track for the partition 402. The partition 402 is used to divide the internal space and position the refrigeration box 405. The second protective shell 502 in the quick-release mechanism 5 is used to accommodate the internal components and fix them to the box 2. The first connecting block 503 and the second connecting block 507 are used to receive the pressing pressure from the protrusion on the box cover 1. The pull rod 504 is used to transmit the movement of the connecting blocks to the crossbar 505. The rod of 5 slides in the grooves of the first limiting block 506 and the second limiting block 508, and forms a mechanical limit on the buckle 5010 when it is locked. The spring 509 is compressed when the second connecting block 507 is pressed to store elastic energy, which is used to provide a restoring force after the external force is released. The hook at the upper end of the buckle 5010 is locked by engaging with the snap-fit ​​edge of the cover 1. The first protective shell 501 acts as a physical stop, supporting the buckle 5010 when it is opened to prevent it from rotating excessively. As for the type of refrigerant filled inside the cooling box 405, the specific material of the insulation layer 403, and the structural form of the rotating shaft 3, those skilled in the art can make conventional designs according to actual usage requirements. These are all well-known technologies in the field and will not be described in detail here.

[0025] Working principle: When the transport box is needed, firstly, move the partition 402 upward along the groove 401 on the inner wall of the box 2 to remove it, take out the refrigeration box 405 fixed by the base 404 and fill it with refrigerant, then install the refrigeration box 405 back in its original position and put the partition 402 back in. After placing the reagents, close the box lid 1 and press the box lid 1 down. The box lid 1 squeezes the buckle 5010. The movement of the buckle 5010 is driven by the pull rod 504 to drive the crossbar 505 to move along the sliding groove of the first limit block 506 and the second limit block 508 until it is locked. At this time, the crossbar 505 limits the buckle 5010, and the hook of the buckle 5010 is engaged with the locking edge of the box lid 1 to complete the locking. During transportation, the refrigerant in the refrigeration box 405... The insulation layer 403 and the sealing ring 406 work together to reduce the ingress of external heat and the loss of internal cold, maintaining a low temperature inside the box. When the transport box needs to be opened, press down on the box cover 1. The groove on the box cover 1 applies a downward force to the first connecting block 503 and the second connecting block 507. The second connecting block 507 moves downward and compresses the spring 509. At the same time, the first connecting block 503 and the second connecting block 507 drive the crossbar 505 to move along the sliding groove of the first limiting block 506 and the second limiting block 508 through the pull rod 504. When the crossbar 505 is completely disengaged from the locking position, the limit on the buckle 5010 is released. The buckle 5010 opens outward, and its movement is blocked and limited by the first protective shell 501. At this time, the box cover 1 is unlocked and can be rotated around the pivot 3 to open.

[0026] 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.
