Description

Technical Field

[0001] This utility model relates to the field of sample storage box technology, specifically to a sample storage box with a limiting function. Background Technology

[0002] Sample storage boxes are important devices used to store and protect test tube samples. In order to prevent biological samples from being damaged or deteriorated and thus affecting the test results, biological samples generally need to be stored or transported in storage boxes.

[0003] Existing sample storage boxes lack a limiting function. For example, in a laboratory reagent tube storage device disclosed in patent CN220918925U, although the high-elasticity sponge in the patent can provide some elastic support, its limiting effect is relatively weak. When the storage box is vibrated or shaken, the reagent tube may still move within the elastic range of the high-elasticity sponge, failing to ensure the absolute stability of the reagent tube. Consequently, the elasticity of the high-elasticity sponge may not be able to adapt to reagent tubes of different sizes and shapes. For thinner or thicker reagent tubes, the high-elasticity sponge may not be able to provide sufficient clamping force or may damage the reagent tube due to excessive compression. Due to the poor limiting effect, the reagent tubes may collide or break with each other due to movement within the storage box, leading to sample leakage or contamination and threatening sample safety.

[0004] Therefore, it is necessary to invent a sample storage box with a limiting function to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a sample storage box with a limiting function to solve the problem of the lack of a limiting function in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sample storage box with a limiting function, comprising a box body, a first shelf, and a second shelf. The first shelf and the second shelf are arranged inside the box body. A support shaft seat is arranged on the rear side above the first shelf and the second shelf. A limiting plate is hinged to the support shaft seat. A groove is opened on the side wall of the limiting plate to match the storage groove, and a sponge pad is also arranged inside the groove. A limiting screw is provided through the limiting plate. Screw holes are opened at the contact positions of the first shelf and the second shelf with the limiting screw. Slider blocks are arranged on the left and right side walls of the second shelf. Sliding grooves are opened on the left and right side walls of the inner wall of the box body at the contact positions with the sliders. The sliders and the sliding grooves are slidably connected.

[0007] Preferably, a lid is snapped onto the top of the box, and latches are provided on the left and right sides of the connection between the box and the lid. The latches facilitate the opening and closing of the lid while ensuring the safety of the box.

[0008] Preferably, the side walls on the left and right sides of the outer side of the box are provided with fixed seats, and the fixed seats are hinged with handles. The hinged design allows the handles to rotate flexibly, providing a convenient way to carry the box, so that the storage box can be easily lifted and moved.

[0009] Preferably, the first shelf is located directly above the second shelf. The first shelf is fixedly installed on the inner wall of the box, and the second shelf is slidably installed inside the box, which realizes the storage of different types of samples and makes flexible use of the internal space of the box.

[0010] Preferably, the first and second shelves are provided with multiple storage slots, and the inside of the storage slots is provided with sponge pads, which can also play a cushioning role and protect the reagent tubes from collisions and impacts.

[0011] Preferably, the front wall of the second shelf is provided with a first label frame, and the front wall of the outer side of the box is provided with a second label frame located directly in front of the first shelf. The first and second label frames are made of transparent material, which facilitates the labeling and classification of reagent tubes and makes it easy to quickly identify and retrieve the reagent tubes.

[0012] Preferably, triangular bearing seats are provided on the left and right side walls of the outer side of the box body. An adjusting plate is hinged to the triangular bearing seat. A fixing screw passes through the adjusting plate and extends into the interior of the second shelf. A screw groove is provided at the contact position between the second shelf and the fixing screw. There are two fixing screws. The outer threads of the two fixing screws are engaged with the inner threads of the screw groove. The engagement of the fixing screws and the screw groove realizes the locking and fixing of the second shelf, ensuring its stability during storage or transportation.

[0013] Preferably, the bottom surface of the box lid is provided with a first top plate, which is located directly above the first shelf. The bottom surface of the first top plate is in contact with the top surface of the limiting plate on the first shelf. A second top plate is provided below the first shelf and is located directly above the second shelf. The side walls on the left and right sides of the second top plate are installed on the inner wall of the box. The bottom surface of the second top plate is in contact with the top surface of the limiting plate on the second shelf, so that the first top plate presses on the limiting plate on the first shelf for limiting, and the second top plate presses on the limiting plate on the second shelf for limiting, further improving the limiting and fixing of the reagent tube by the limiting plate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model achieves efficient positioning of reagent tubes by setting hinged limiting plates above the first and second shelves, and cooperating with the limiting screws and screw holes. Furthermore, the first top plate on the bottom surface of the box lid and the second top plate below the first shelf contact the top surfaces of the limiting plates on the first and second shelves respectively, forming a "clamping" effect, which further improves the fixing effect of the limiting plates and ensures the absolute stability of the reagent tubes in the storage box.

[0016] 2. This utility model features a first shelf and a second shelf, each with multiple storage slots, allowing for the storage of different types of samples and meeting diverse storage needs. Furthermore, both the first label frame on the front wall of the second shelf and the second label frame on the outer front wall of the box (located directly in front of the first shelf) are made of transparent material, facilitating the identification and classification of reagent tubes. This design enables users to quickly identify and retrieve the required reagent tubes, improving work efficiency. Attached Figure Description

[0025] This utility model provides, for example Figure 1-5 The sample storage box shown includes a box body 1, a first shelf 6, and a second shelf 7. A lid 2 is snap-fitted onto the top of the box body 1. Locks 3 are provided on both sides of the connection between the box body 1 and the lid 2. Fixing seats 4 are provided on the left and right side walls of the outer sides of the box body 1, and handles 5 are hinged to the fixing seats 4. The first shelf 6 and the second shelf 7 are arranged inside the box body 1. A support shaft seat 10 is provided on the rear side above the first shelf 6 and the second shelf 7. A limiting plate 11 is hinged at the top. The groove on the side wall of the limiting plate 11 matches the storage slot 9, and a sponge pad 8 is also provided inside the groove. A limiting screw 12 is provided through the limiting plate 11. Screw holes 13 are provided at the contact positions between the first storage rack 6 and the second storage rack 7 and the limiting screw 12. Slider blocks 14 are provided on the side walls of the left and right sides of the second storage rack 7. Sliding grooves 15 are provided at the contact positions between the left and right sides of the inner wall of the box 1 and the slider 14. The slider 14 and the sliding groove 15 are slidably connected.

[0026] Shelf 6 is located directly above shelf 7. Shelf 6 is fixedly installed on the inner wall of the box 1. Shelf 7 is slidably installed inside the box 1. Shelf 6 and shelf 7 have multiple storage slots 9. The storage slots 9 are filled with sponge pads 8. Shelf 7 has a label frame 16 on its front wall. Shelf 7 has a label frame 17 on its outer front wall, located directly in front of shelf 6. Label frames 16 and 17 are made of transparent material.

[0027] In this embodiment, the fixed installation of shelf 6 and the sliding installation of shelf 7 enable the layered utilization and flexible adjustment of the internal space of the box 1. Users can classify and store samples according to their different storage needs. The setting of label box 16 and label box 17 facilitates the identification and classification of samples, enabling users to quickly identify and retrieve the required samples, thus improving sample retrieval efficiency.

[0028] Triangular bearing seats 18 are provided on the left and right side walls of the outer side of the box body 1. Adjustment plates 19 are hinged to the triangular bearing seats 18. Fixing screws 20 pass through the adjustment plates 19 and extend into the interior of the second shelf 7. A screw groove 21 is provided at the contact position between the second shelf 7 and the fixing screw 20. There are two fixing screws 20. The outer threads of the two fixing screws 20 are engaged with the inner threads of the screw groove 21. A top plate 22 is provided on the bottom surface of the box cover 2. The top plate 22 is located directly above the first shelf 6. The bottom surface of the top plate 22 is in contact with the top surface of the limiting plate 11 on the first shelf 6.

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual appendix Figure 1-2 When using this utility model, first, unlock the latch 3 to open the box cover 2, and slide out the second shelf 7 by sliding the slider 14 and the slide groove 15. Then, according to the type of sample reagent tube, select the first shelf 6 or the second shelf 7 for placement. If it is necessary to store them separately, different types of samples can be placed on different shelves, and different labels can be placed in the first label frame 16 and the second label frame 17 for easy identification later. Then, gently place the sample reagent tube into the selected storage slot 9, and then flip the limiting plate 11 forward so that the groove opened on the side wall of the limiting plate 11 matches the storage slot 9. Then, pass the limiting screw 12 through the hole on the limiting plate 11 and align it with the screw hole 13 on the first shelf 6 or the second shelf 7. Finally, tighten the limiting screw 12 so that the limiting plate 11 fits tightly against the top of the reagent tube to achieve limiting and fixing.

[0032] Refer to the instruction manual appendix Figure 3-5When using this utility model, after the reagent tubes are placed, the slider 14 on the side wall of the second shelf 7 can be aligned with the sliding groove 15 on the side wall of the box body 1 for sliding installation. Adjust the adjusting plate 19 to a suitable position, and then tighten the fixing screw 20 to firmly lock the second shelf 7 inside the box body 1. After the second shelf 7 is installed in place, the second top plate 23 contacts the top surface of the limiting plate 11 on the second shelf 7, further pressing the limiting plate 11 and enhancing the limiting and fixing effect on the reagent tubes on the second shelf 7. Finally, the box cover 2 is gently closed. During the process of closing the box cover 2, it is locked by the buckle 3. The bottom surface of the first top plate 22 will gradually contact the top surface of the limiting plate 11 on the first shelf 6 and press the limiting plate 11, thereby achieving the final limiting and fixing effect on the reagent tubes on the first shelf 6.

[0033] By following the above steps, the sample reagent tubes can be safely and stably placed inside the sample storage box with limiting function.
