Description

TECHNICAL FIELD

[0001] The present application relates to the field of sample rack transportation, in particular to a sample rack carrying anti-toppling basket. BACKGROUND

[0002] In medical testing, central laboratories and various research laboratories, sample racks (or test tube racks) are the main carriers of key biological samples such as blood sample tubes and urine sample tubes. Laboratory workers need to frequently transfer multiple sample racks loaded with samples between different work areas (such as sample receiving tables, pre-processing areas, and analytical instrument areas) on a daily basis. This transfer process is an important part of the laboratory workflow, and the convenience and reliability of the operation directly affect sample safety, detection efficiency, and biological safety.

[0003] The common sample rack transfer methods in laboratories mainly include direct hand transfer and transfer using general trays or baskets. In addition, there are some specially designed transfer containers with locking mechanisms or simple limiting structures that attempt to fix the sample racks during transfer.

[0004] These existing transfer methods still have obvious deficiencies. When directly holding or using general containers, the sample racks lack effective constraints and are prone to sliding, colliding with each other, or even toppling over during transfer, which poses a risk of sample spillage, cross-contamination, and biological safety. Moreover, the number of samples that can be transferred at one time is limited, and the efficiency is low. Some transfer containers with locking mechanisms improve stability, but they often require manual unlocking, locking, or operating independent limiting components during loading and unloading, which is cumbersome and affects the continuity and convenience of the workflow, failing to meet the needs of fast, safe, and seamless switching during transfer.

[0016] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0017] The embodiments of the present application will be described below according to the overall structure of the present application.

[0018] A sample rack carrying anti-falling basket, please refer to Figures 1 to 4 , comprising a basket body, a basket upper handle 4, a basket test tube rack guide block 1 and a set of key barb mechanisms.

[0019] The basket body constitutes the base body of the device, and the core component is the basket groove plate 3. The basket groove plate 3 is in a long strip plate structure, used to carry and arrange other functional components. At the front end of the basket groove plate 3, i.e. in the direction in which the sample rack 7 is expected to slide out, a basket front stand plate 6 is fixedly arranged. The stand plate can be used as the final mechanical limit for the forward movement of the sample rack 7, preventing it from sliding out too much. On the side plates of the basket groove plate 3, symmetrically fixedly connected are basket handle connecting blocks 5. The two ends of the basket upper handle 4 are fixedly connected with the left and right basket handle connecting blocks 5 respectively, thereby forming an overall handle structure which is convenient for the user to grasp and carry. In addition, on the side plates of the basket groove plate 3, there are also basket guide entry blocks 8. The basket guide entry blocks 8 can be protrusions or grooves, and their design is matched with the corresponding structures on the external automated equipment or workbench surface, used to provide the functions of guiding entry, accurate limiting and error-proofing when the basket is placed into the equipment.

[0020] The basket test tube frame guide block 1 is a key component for carrying and guiding the sample frame 7. It is fixedly installed on the upper surface of the basket groove plate 3 and extends along the length direction of the basket groove plate 3. Its cross section is designed as a T-shaped structure, which can be precisely fitted and matched with the T-shaped groove usually provided on the bottom of the general sample frame 7. When the sample frame 7 is placed thereon, the T-shaped structure can effectively limit the shaking of the sample frame 7 and prevent it from turning over. An important feature is that the basket test tube frame guide block 1 is not centrally arranged in the width direction of the basket groove plate 3, but is intentionally biased to one side (for example, close to one side plate). This biased arrangement makes the sample frame 7 only be able to slide into the length direction from a specific and correct direction (i.e. from the rear end of the basket test tube frame guide block 1) and achieve the fitting of the T-shaped structure. If the operator tries to load from the wrong direction or angle, it cannot be successful, thereby achieving forced error-proof loading and preventing mixed loading, ensuring that all sample frames 7 in the basket are kept in the same direction and arranged in order. In order to facilitate the initial loading of the sample frame 7, a guide block inlet chute 2 is specially provided at the rear end of the basket test tube frame guide block 1 away from the barb mechanism. The chute 2 provides a gradually narrowing guide slope, which can guide the T-shaped slot at the bottom of the sample frame 7 to easily and accurately align and slide into the T-shaped basket test tube frame guide block 1, making the loading operation more smooth and labor-saving.

[0021] The barb mechanism is the core of the invention to realize the automatic locking and unlocking function, which is arranged at the front end of the basket test tube frame guide block 1. The mechanism mainly includes a basket front stop plate 9, a basket rear stop plate 10, a basket turning shaft compression spring 12 and a headless shaft position screw 11. The basket front stop plate 9 and the basket rear stop plate 10 are rotatably connected to the reserved mounting position at the front end of the basket test tube frame guide block 1 through the headless shaft position screw 11 as a common rotation axis. The basket turning shaft compression spring 12 (usually a torsion spring or a compression spring) is accommodated in the corresponding groove or circular hole at the front end of the basket test tube frame guide block 1, one end of which acts on the basket test tube frame guide block 1 and the other end of which acts on the basket front stop plate 9, thereby providing the basket front stop plate 9 with a spring force to keep it outwardly (usually pointing to the direction of the basket front vertical plate 6) pop-out tendency.

[0022] The barb mechanism has two stable working states: Closed state (such as Figure 3(As shown): In this state, the elastic force of the basket tilting spring 12 drives the front stop plate 9 of the basket to pop outward. Since the front stop plate 9 and the rear stop plate 10 of the basket are linked by the headless shaft screw 11, the popping movement of the front stop plate 9 drives the rear stop plate 10 of the basket to rotate upward around the axis through its connecting structure (which can be regarded as a linkage mechanism), so that the hook part at the upper end of the rear stop plate 10 protrudes from the upper surface of the basket test tube rack guide block 1. This protruding hook forms an effective physical barrier at the front end of the basket test tube rack guide block 1, preventing the sample rack 7 on it from continuing to slide forward, thereby preventing the sample rack 7 from slipping off from the front or tipping over during transportation.

[0023] Open state (e.g.) Figure 4 As shown): In this state, a downward external pressure (e.g., the pressure of the platform surface on the front stop plate 9 of the basket when it is placed on the work platform) acts on the front stop plate 9 of the basket, overcoming the elastic force of the basket flipping shaft compression spring 12, causing it to retract inward (towards the basket groove plate 3). This retraction movement also drives the rear stop plate 10 of the basket to rotate in the opposite direction (downward) around the axis through the linkage structure, causing the hook at its upper end to descend to a position lower than or flush with the upper surface of the basket test tube rack guide block 1. At this time, the physical barrier in front is removed, and the sample rack 7 can slide forward along the basket test tube rack guide block 1 without obstruction, making it easy to remove.

[0024] In a preferred embodiment, the basket handle 4, the basket handle connecting block 5, and the basket front stop plate 9 are connected by a mechanical structure (such as direct contact, linkage, or cam structure) to form a linkage system. When the operator lifts the basket handle 4 to prepare for transport, this action is transmitted through the basket handle connecting block 5, causing the basket front stop plate 9 to lose the constraint of the platform below and automatically spring up under the action of the basket flipping shaft compression spring 12, thereby driving the entire hook mechanism to instantly enter the closed state and automatically locking all sample racks 7. Conversely, when the transport is completed and the basket is placed on the work platform, the platform surface applies pressure to the basket front stop plate 9, forcing it to retract, thereby driving the hook mechanism to switch to the open state and automatically unlocking. This process achieves immediate closing when lifting the basket and immediate opening when placing it, without any additional manual opening and closing operations, greatly improving efficiency and convenience.

[0025] In operation, first place the basket on the workbench. At this time, the barb mechanism is in the open state. The sample rack 7 is guided from the rear end by the guide block entry chute 2, and slides onto the offset basket test tube rack guide block 1. Multiple sample racks 7 can be arranged in sequence. When it is necessary to transport, directly lift the basket handle 4, and the barb mechanism automatically closes and locks the sample rack 7. Even if the basket is tilted and shaken during walking and turning, the sample rack 7 is firmly fixed by the T-shaped guide and the front barb, and will not fall off. After reaching the destination, place the basket back on the table, and the barb mechanism automatically opens. The sample rack 7 can be pushed out one by one, and unloading is completed.

[0026] Although the embodiments of the present application have been shown and described, the specific embodiments are merely illustrative of the present application, and are not intended to limit the present application. The specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner, and those skilled in the art can make modifications, replacements and variations of the embodiments without creative contribution after reading the specification, as long as they are within the scope of the present application.
