[0021] Explanation of reference numerals in the attached figures Detailed Implementation

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] The reagent tube device of this utility model is described below with reference to the accompanying drawings.

[0024] like Figures 1 to 5 As shown, the first aspect of this utility model provides a reagent tube device, comprising: The reagent tube body 1 includes a plurality of tube body parts 11 and a plate body part 12 extending from the tube opening edge of the plurality of tube body parts 11 and connecting each tube body part 11. The tube opening of the tube body part 11 is provided with a sample dispensing channel 513 for the sample dispensing tube to pass through, and the plate body part 12 is provided with a first snap-fit ​​part 121. The cover assembly includes a first cover 2, a second cover 3, and a cover connecting strip 4 connecting the first cover 2 and the second cover 3 on the same side. The first cover 2 is attached to the plate part 12 and has a cover opening 21 that corresponds one-to-one with the openings of a plurality of tube parts 11. The second cover 3 has a plug part 31 corresponding to each cover opening 21. The plug part 31 extends from the cover opening 21 into the tube opening for plugging and sealing. The first cover 2 has a second snap-fit ​​part 22 that snaps into the first snap-fit ​​part 121. A connecting structure is provided between the first cover 2 and the second cover 3 for splicing the first cover 2 and the second cover 3.

[0025] When using the above-described reagent tube device, the tube body 11 is used to contain relevant samples and reagents. Several tube bodies 11 are connected by a plate body 12, enabling integrated storage and management of multiple samples or reagents, effectively reducing the potential confusion or loss problems that may occur when individual reagent tubes are stored independently. The first cover 2 is attached to the plate body 12 and has capping openings 21 that correspond one-to-one with the openings of several tube bodies 11. The second cover 3 is connected to the first cover 2 by a cover connecting strip 4, and the second cover 3 has a plug part 31 corresponding to each capping opening 21. When adding samples through the sample tube, the second cover 3 opens, and the sample tube can close itself. The filling port 21 extends into the tube body 11 for operation. After the sample is added, the second cover 3 can be flipped over so that the plugging part 31 extends from the cover opening 21 into the sample adding channel 513 for plugging and sealing, reducing the risk of leakage or external contamination of the sample or reagent during storage and transportation. To ensure the reliability of the connection between the first cover 2 and the reagent tube body 1, the plate body 12 is provided with a first snap-fit ​​part 121, and at least one of the first cover 2 and the second cover 3 is provided with a second snap-fit ​​part 22 that snaps into the first snap-fit ​​part 121. Through the snap-fit, the cover assembly can be prevented from falling off during operation or transportation.

[0026] Specifically, the first snap-fit ​​part 121 is a through hole inside the plate part 12, and the second snap-fit ​​part 22 is provided on the second cover 3. The second snap-fit ​​part 22 passes through the through hole and abuts against the lower plate surface of the plate part 12. The second snap-fit ​​part 22 has a vertical rod that can be elastically bent under pressure. The end of the vertical rod is provided with an outwardly protruding barb. When it is necessary to install the first cover 2 onto the plate part 12, the vertical rod of the second snap-fit ​​part 22 can be aligned with the through hole and pressure can be applied. The vertical rod will be elastically bent under the pressure of the inner wall of the through hole, allowing the barb to pass smoothly through the through hole. After the barb has completely passed through the through hole, the vertical rod returns to its original shape, and the barb abuts tightly against the lower plate surface of the plate part 12, thereby achieving a stable connection between the first cover 2 and the plate part 12. This snap-fit ​​structure is simple in design and easy to operate, and installation can be completed simply by pressing. Furthermore, the second snap-fit ​​part 22 is provided on the first cover 2, which allows the cover plate assembly and the reagent tube body 1 to be connected and engaged when the second cover 3 is in the open state.

[0027] Of course, this utility model is not limited to this. The structures of the first latching part 121 and the second latching part 22 can be interchanged, that is, the second latching part 22 can be set as a through hole, and the first latching part 121 passes through the through hole and abuts against the lower plate surface of the plate body part 12. Alternatively, the second latching part 22 can also be provided on the second cover body 3.

[0028] like Figures 1 to 3 As shown in this embodiment of the utility model, the plate body 12 is further provided with a third snap-fit ​​part 122. The third snap-fit ​​part 122 is centrally located along the length direction of the plate body 12. The third snap-fit ​​part 122 is located on the side of the plate body 12 away from the cover connecting strip 4. The plate body 12 is provided with a first snap-fit ​​part 121 at least one tube body part 11 spaced apart from the third snap-fit ​​part 122 along the length direction. The first cover 2 is provided with a second snap-fit ​​part 22 on the side facing the plate body 12. The second cover 3 is provided with a fourth snap-fit ​​part 32 as a connecting structure. The first cover 2 is provided with a clearance space 25 for the third snap-fit ​​part 122 and the fourth snap-fit ​​part 32 to snap-fit ​​together. The cooperation between the third latching part 122 and the fourth latching part 32 can further enhance the connection stability between the cover assembly and the plate body 12. When the first cover 2 and the second cover 3 are both covered on the plate body 12, the third latching part 122 can pass through the clearance space 25 and form a latching with the fourth latching part 32, so that the second cover 3 is kept in the state of covering the cover opening 21, and the plugging part 31 is prevented from falling out due to improper transportation or operation.

[0029] Specifically, the third latching part 122 is a notch on the edge of the plate part 12, and the fourth latching part 32 passes through the clearance space 25 and the notch in sequence and abuts against the lower plate surface of the plate part 12. The second latching part 22 has a vertical plate that can be elastically bent and deformed under pressure. The end of the vertical plate is provided with an outwardly protruding barb. When the second cover 3 is closed on the first cover 2, the vertical plate passes through the clearance space 25 and the notch. During the passage, the barb causes the vertical plate to bend outward due to pressure. After the barb has completely passed through the notch, the vertical plate returns to its elastic deformation, and the barb abuts against the lower plate surface of the plate part 12, thereby realizing a stable latching between the second cover 3 and the plate part 12. This elastic latching structure design makes the closing and opening operation of the second cover 3 convenient and labor-saving.

[0030] Of course, this utility model is not limited to this; the structures of the third latching part 122 and the fourth latching part 32 can also be interchanged. If the second cover 3 does not need to be opened after being closed, the third latching part 122 and the fourth latching part 32 can be removed, and the second cover 3 can be fixed by applying sealant to the first cover 2 and / or the second cover 3.

[0031] like Figure 3 As shown in this embodiment of the invention, a plurality of tube portions 11 are arranged sequentially at intervals along the length direction of the plate portion 12. First locking portions 121 are provided on both opposite sides of the third locking portion 122, and each first locking portion 121 includes two through holes spaced apart along the width direction of the plate portion 12. Second locking portions 22 are correspondingly arranged with the first locking portions 121. The third locking portion 122 is centrally located, and in conjunction with the distribution of multiple sets of first locking portions 121, a symmetrical force-bearing structure can be formed on the plate portion 12, further improving the stability of the connection between the first cover 2, the second cover 3, and the plate portion 12.

[0032] like Figure 4 and Figure 5 As shown in this embodiment of the invention, the reagent tube device further includes a rubber stopper module. The rubber stopper module includes several rubber stopper bodies 51 and rubber stopper connecting strips 52. The rubber stopper bodies 51 are inserted into the opening of the tube body 11 and form a sample dispensing channel 513 for the sample tube to pass through. The plugging part 31 extends into the sample dispensing channel 513 to perform plugging and sealing. The rubber stopper connecting strips 52 connect adjacent rubber stopper bodies 51. The rubber stopper bodies 51 are made of elastic silicone material, and their outer peripheral surface is tightly fitted to the inner wall of the opening of the tube body 11, which can effectively prevent reagent leakage or external contaminants from entering the tube body 11. The rubber stopper connecting strips 52 connect multiple rubber stopper bodies 51 for easy removal and assembly.

[0033] like Figure 4As shown, in this embodiment of the invention, the stopper 51 includes an outer ring portion 511 and an inner ring portion 512. The inner ring portion 512 is disposed within the outer ring portion 511 and forms a sample dispensing channel 513. A connecting groove 514 is formed between the inner ring portion 512 and the outer ring portion 511 at a distance. A connecting portion 23 embedded in the connecting groove 514 is formed around the periphery of the capping opening 21. The outer ring portion 511 and the inner ring portion 512 form a wrapping structure on the inner and outer sides of the connecting portion 23, effectively preventing the stopper 51 from loosening or falling off due to external force during use, and improving the sealing effect between the stopper 51 and the first cap 2. Furthermore, the inner ring portion 512 extends into the capping opening 21 and is sealed and fitted against the side wall of the capping opening 21 to prevent contaminants from entering the connecting groove 514.

[0034] like Figure 4 As shown, in this embodiment of the invention, a sealing ring portion 515 is provided on the outer wall of the outer ring portion 511, and a sealing groove for the sealing ring portion 515 to be embedded is formed on the inner wall of the tube body portion 11. The sealing ring portion 515 and the groove wall of the sealing groove are sealed together, improving the reliability of the seal. Specifically, the rubber stopper 51 is preferably made of soft rubber, while the tube body portion 11 is made of hard material. By extrusion deformation, the sealing ring portion 515 is made into full contact with the groove wall of the sealing groove. Furthermore, the number of sealing ring portions 515 is set to two or more, corresponding to the number of sealing grooves, thereby ensuring the sealing effect through multiple seals.

[0035] like Figure 2 As shown in this embodiment of the invention, the first cover 2 has a receiving groove 24 for accommodating the glue plug connecting strip 52 on the side facing the plate portion 12. Therefore, there is no interference between the first cover 2 and the cover plate portion, allowing them to fit together and improving the connection and sealing effect. Specifically, a second snap-fit ​​portion 22 is provided on both sides of the receiving groove 24.

[0036] like Figure 5 As shown in this embodiment of the invention, a notch 516 is provided on the bottom wall of the sample dispensing channel 513. The notch 516 is used to open under the pressure of the sample dispensing tube to allow the sample dispensing tube to enter the tube body 11. Before the sample dispensing operation, the second cover 3 is in the open state. At this time, the notch 516 is in the closed state, and the inner cavity of the tube body 11 is still isolated from the outside. When dispensing the sample, the sample dispensing tube is pressed down to open the notch 516 and extend into the tube body 11. After the sample dispensing is completed, the sample dispensing tube is removed, and the notch 516 elastically resets to reseal the tube body 11. By providing a notch 516 on the rubber stopper 51, it can be ensured that the tube body 11 is in a sealed state in most cases, preventing gas exchange with the outside air, avoiding the generation of aerosols, and achieving the effect of preventing pollution.

[0037] During large-scale testing, multiple reagent tube devices are typically placed on a single test tube rack. With the second cover 3 open, it is prone to interference with adjacent reagent tube devices. Understandably, the shorter the length of the cover connecting strip 4, the greater the resistance when bending; therefore, simply shortening the length of the cover connecting strip 4 cannot prevent interference. Figure 1 and Figure 2 As shown, in this embodiment of the invention, the cover connecting strip 4 is inclined in the horizontal direction. The inclined cover connecting strip 4 can effectively shorten the distance between the first cover 2 and the plate part 12, and ensure that the cover connecting strip 4 has sufficient length for easy bending.
