For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] like Figures 1-13 As shown, this embodiment provides a consumable storage device 100 for storing consumables 200. The consumables 200 can be ordinary test tubes, multi-tube test tubes, etc., and are not limited thereto.

[0045] The consumable storage device 100 includes a storage rack 1, a cover 2, and a locking assembly 3. The storage rack 1 has a storage position 11 for storing consumables 200. The cover 2 has a sampling hole 211. The cover 2 is pressed onto the storage rack 1 so that the sampling hole 211 is directly opposite the storage position 11. The sealing film on the consumables 200 is located between the cover 2 and the storage rack 1. The locking assembly 3 includes a locking member 31 and a locking seat 32. The locking member 31 is located on the cover 2, and the locking seat 32 is fixedly installed on the storage rack 1. The locking member 31 can be locked onto the locking seat 32. The locking component 3 allows the cover 2 to lock onto the storage rack 1. When the pipette draws up the reagent and removes the sealing film, the cover 2 locks onto the storage rack 1, pressing the sealing film between the cover 2 and the storage rack 1. The pipette will not lift the sealing film or the consumable 200, thus preventing the consumable 200 from being damaged and avoiding reagent spillage and cross-contamination. This ensures smooth pipetting and, consequently, guarantees the efficiency and accuracy of sample testing.

[0046] When consumable 200 is a regular test tube or a series of test tubes, consumable 200 is placed on storage rack 1, and reagents are stored inside consumable 200. Specifically, storage rack 1 can be a polymerase chain reaction (PCR) plate, deep well plate, test tube rack, styrene-butadiene-styrene block copolymer (SBS) plate holder, etc., and is not limited thereto.

[0047] like Figures 1-6 As shown, the locking member 31 includes a first latching part 311, on which a latching groove 316 is provided, and the locking seat 32 includes a second latching part 321, which can be locked onto the latching groove 316.

[0048] Furthermore, the locking member 31 is rotatably mounted on the cover 2. By rotating the locking member 31, the second latching part 321 can be locked or unlocked with the slot 316.

[0049] Furthermore, the locking assembly 3 also includes a locking shaft 34, which is fixedly installed on the cover 2, and the locking member 31 is rotatably mounted on the locking shaft 34.

[0050] Specifically, the locking member 31 has a locking rotating hole 314, and the end of the locking rotating shaft 34 is located in the locking rotating hole 314. By manually rotating the locking member 31, the locking member 31 can rotate around the locking rotating shaft 34, causing the first locking part 311 to rotate, so that the second locking part 321 can be locked or unlocked from the slot 316. When the second locking part 321 is locked in the slot 316, the cover 2 is locked on the storage rack 1, which can prevent the pipette from carrying away the consumable 200, thus preventing the consumable 200 from being broken. It also avoids reagent spillage and cross-contamination of reagents, ensuring smooth pipetting and thus ensuring the efficiency and accuracy of sample detection. When the second locking part 321 is unlocked from the slot 316, the cover 2 and the storage rack 1 can be separated, making it easy to put in and take out the consumable 200.

[0051] Furthermore, the locking assembly 3 also includes an elastic element 33, which is used to keep the slot 316 locked in the second latching portion 321. Specifically, one end of the elastic element 33 is connected to the cover 2, and the other end is connected to the locking element 31. More specifically, the elastic element 33 may be a spring.

[0052] In this embodiment, the slot 316 and the elastic element 33 are respectively disposed on both sides of the locking shaft 34, and the elastic element 33 is always in a compressed state. In other optional embodiments, the slot 316 and the elastic element 33 may both be located on the same side of the locking shaft 34, and the elastic element 33 is always in a stretched state.

[0053] In this embodiment, when the locking member 31 is manually rotated, the second locking part 321 disengages from the slot 316, and the cover 2 opens to facilitate the handling of consumables 200. During this process, the elastic member 33 is compressed. When the manual force on the locking member 31 is removed, the locking member 31 resets under the elastic force of the elastic member 33, so that the second locking part 321 engages with the slot 316.

[0054] Furthermore, the cover 2 has a first spring-loaded hole 233, the locking member 31 has a second spring-loaded hole 313, one end of the elastic member 33 is connected to the first spring-loaded hole 233, and the other end is connected to the second spring-loaded hole 313.

[0055] like Figure 5 As shown, the locking member 31 has a through hole 315, through which a person can hold the locking member 31 by hand, making it easy to rotate the locking member 31. The through hole 315 can also reduce weight.

[0056] like Figure 2 , Figure 6 and Figure 7 As shown, the locking seat 32 also includes a seat body 322, which is connected to the second latching part 321 and is fixedly mounted on the storage rack 1. Specifically, the seat body 322 and the second latching part 321 are integrally formed.

[0057] Furthermore, the storage rack 1 has a locking mounting cavity 12, and the main body 322 is fixedly installed in the locking mounting cavity 12.

[0058] Furthermore, the locking assembly 3 also includes a second fastener 36. A second fastening hole 323 is provided on the seat body 322. The second fastener 36 passes through the second fastening hole 323 and is threadedly connected to the threaded hole provided in the locking mounting cavity 12.

[0059] Furthermore, the second latching part 321 protrudes from the seat body 322 to form a relief cavity 324, which is used to avoid the first latching part 311.

[0060] like Figure 7 and Figure 9As shown, the locking assembly 3 also includes a first fastener 35. The cover 2 has a communicating locking shaft cavity 231 and a first fastening hole 232. The first fastener 35 is fastened to the first fastening hole 232 to press the locking shaft 34 into the locking shaft cavity 231. During installation, the locking shaft 34 is first sleeved into the locking rotating hole 314, with both ends of the locking shaft 34 extending out of the locking rotating hole 314. Then, the portion of the locking shaft 34 with the locking element 31 extending out of the locking rotating hole 314 is placed into the locking shaft cavity 231. The first fastener 35 is then threaded into the first fastening hole 232, with the larger end of the first fastener 35 pressing against the locking shaft 34, so that the locking shaft 34 is fixedly installed on the cover 2.

[0061] Specifically, the cover 2 includes a cover body 21 and a locking connection part 23 connected to each other. A sampling hole 211 is opened on the cover body 21, and a locking shaft cavity 231, a first fastening hole 232 and a first spring contact hole 233 are all opened on the locking connection part 23.

[0062] like Figures 7-10 As shown, the consumable storage device 100 also includes a rotating assembly 4, and one end of the cover 2 is rotatably mounted on the storage rack 1 via the rotating assembly 4. This configuration makes the consumable storage device 100 a flip-top type, which facilitates opening and closing the cover 2, and thus facilitates taking consumables 200 from the storage rack 1.

[0063] In other alternative embodiments, such as Figure 11As shown, the rotating component 4 can also be omitted, allowing the cover 2 and storage rack 1 to be separate units, locked together by the locking component 3. A locking seat 14 is provided on the side of the storage rack 1, with a locking hole 141. The locking component 3 includes a locking buckle 37, made of elastic material such as plastic. The locking buckle 37 includes a locking protrusion 371 and a buckle connecting part 372. The locking protrusion 371 protrudes from the buckle connecting part 372 away from the cover 2. When the buckle connecting part 372 is not subjected to external force, the locking protrusion 371 is not directly aligned with the locking hole 141; instead, the locking protrusion 371 passes through the locking hole 141 and abuts against the bottom surface of the locking seat 14. The locking protrusion 371 locks onto the locking seat 14, locking the cover 2 onto the storage rack 1, preventing the consumable 200 from being lifted by the sealing film. When the snap-fit ​​connection 372 is pressed towards the side where the cover 2 is located, the snap-fit ​​connection 372 tilts towards the cover 2, making the locking protrusion 371 aligned with the locking hole 141. Lifting the cover 2 upwards will cause the locking protrusion 371 to move upwards, disengaging it from the locking hole 141, thus unlocking the cover 2 from the storage rack 1. The cover 2 can then be removed from the storage rack 1 for the storage of the consumable 200. Due to the elasticity of the locking snap 37, the snap-fit ​​connection 372 returns to its original shape when the external force is removed, allowing the locking snap 37 and the locking seat 14 to switch back and forth between the locked and unlocked states without damaging the locking seat 14 or the locking snap 37.

[0064] It should be noted that when covering, the sampling hole 211 on the cover 2 should be aligned with the opening of the storage position 11 before locking.

[0065] Furthermore, the storage rack 1 has a rotating mounting cavity 13, the rotating assembly 4 includes a rotating shaft, the rotating shaft is fixedly installed in the rotating mounting cavity 13, and the cover 2 includes a rotating connecting part 24, the rotating connecting part 24 is rotatably disposed on the rotating shaft.

[0066] In this embodiment, the rotating shaft includes a first rotating shaft 41 and a second rotating shaft 42. The first rotating shaft 41 and the second rotating shaft 42 are fixedly installed on opposite side walls of the rotating mounting cavity 13. The rotating connection part 24 includes a first connecting part 241 and a second connecting part 242. A first rotating hole 243 is provided on the first connecting part 241, and a second rotating hole 244 is provided on the second connecting part 242. The first rotating shaft 41 is disposed in the first rotating hole 243, and the second rotating shaft 42 is disposed in the second rotating hole 244.

[0067] In this embodiment, the rotating connecting part 24 and the locking connecting part 23 are positioned opposite each other. Of course, other positional relationships are also possible between them, and this embodiment does not limit this.

[0068] like Figure 9 , Figure 10 andFigures 12-13 As shown, the cover 2 also includes a pressing part 22, which protrudes from the cover body 21 toward the storage rack 1. The pressing part 22 can press against the top surface of the support frame 201 of the multiple consumables 200 stored on the storage rack 1.

[0069] Furthermore, the crimping part 22 includes a crimping strip, which protrudes toward the storage rack 1 on the cover body 21 and crimps onto the top surface of the support frame 201 of all consumables 200;

[0070] Alternatively, the crimping part 22 includes a plurality of crimping protrusions 221, which protrude toward the storage rack 1 on the cover body 21. The crimping protrusions 221 are provided one-to-one with the consumables 200, and the crimping protrusions 221 are crimped onto the top surface of the support frame 201 of the corresponding consumables 200.

[0071] Alternatively, the crimping part 22 includes a plurality of crimping protrusions 221, which protrude toward the storage rack 1 on the cover body 21, and two adjacent crimping protrusions 221 are crimped onto the top surface of the support frame 201 of each consumable 200.

[0072] Specifically, in this embodiment, as Figure 2 and Figure 10 As shown, consumable 200 is a series of test tubes, specifically an eight-tube series. Consumable 200 includes a support frame 201, a storage section 202, and a storage protrusion 203. The support frame 201 is provided with multiple storage sections 202, each used to store reagents. A storage protrusion 203 is provided on the opening of each storage section 202. The sampling holes 211 are provided one-to-one with the openings of the storage sections 202 and can be directly opposite each other so that the pipette can draw reagents from the storage sections 202.

[0073] In this embodiment, the storage position 11 includes multiple storage cavities, which are arranged one-to-one with the storage section 202, so that one row of test tubes is stored in one storage position 11. There are multiple storage positions 11, which are arranged at intervals to accommodate more rows of test tubes. Two adjacent pressing protrusions 221 are pressed onto the top surface of the support frame 201 of each consumable 200.

[0074] In other embodiments, when the consumable 200 is a single ordinary test tube, the storage position 11 includes a storage cavity, which is provided in a one-to-one correspondence with the storage section 202. There are multiple storage cavities, arranged in rows and columns on the storage rack 1, to store more single ordinary test tubes.

[0075] Furthermore, when adjacent pressing protrusions 221 are pressed onto the top surface of the support frame 201 of each consumable 200, a clearance groove is formed between two adjacent pressing protrusions 221, and the clearance groove is used to avoid the storage protrusion 203 of the consumable 200.

[0076] Furthermore, the crimping part 22 also includes a crimping protrusion 222, which is provided on opposite sides of the cover body 21. One crimping protrusion 222 is connected to a locking connection part 23, and the other crimping protrusion 222 is connected to a rotating connection part 24. The crimping protrusion 222 is used to crimp the top surface of the support frame 201 located at the edge.

[0077] Furthermore, the cover body 21 is a cuboid, including two sets of opposing sides. One set of opposing sides is provided with a pressing protrusion 222, and the other set of opposing sides is provided with a pressing protrusion 221. When the row of test tubes is placed on the storage position 11 closest to the locking assembly 3 or the rotating assembly 4, the pressing protrusion 222 and the pressing protrusion 221 are pressed together on the top surface of the support frame 201, thereby enabling the pressing part 22 to achieve a better pressing effect on the consumable 200.

[0078] The consumable storage device 100 is a flip-top type with two states: open and closed. When the consumable storage device 100 is in the open state, the locking member 31 is unlocked from the locking seat 32, and the cover 2 rotates around the rotation axis to facilitate the loading and unloading of consumables 200. When the consumable storage device 100 is in the closed state, the locking member 31 is locked to the locking seat 32, the cover 2 cannot rotate around the rotation axis, and the sealing film and consumables 200 are pressed between the cover 2 and the storage rack 1, which can prevent the consumables 200 from being lifted after the pipette is used for pipetting.

[0079] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
