DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Example 1

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, the utility model provides a technical solution: a reagent bottle for liquid collection without opening the lid, comprising a reagent bottle 10, a sealing cover 11 and a sampling needle 12. The sealing cover 11 is threadedly connected to the top of the reagent bottle 10, and a plurality of sealing sheets 13 are fixed in an annular array on the inner wall of the sealing cover 11. Each of the plurality of sealing sheets 13 is a fan-shaped structure, and the plurality of sealing sheets 13 are combined to form a disc structure. An auxiliary sealing component for sealing the reagent bottle 10 is arranged at the top port of the reagent bottle 10, and an anti-leakage component is arranged on the top of the sealing cover 11. During specific use, the reagent bottle 10 is used to store reagents, and the sealing cover 11 is used to close the reagent bottle 10. The sealing sheet 13 is used to provide a sealing effect when the sampling needle 12 is inserted into the reagent bottle 10. The auxiliary sealing component is provided to further ensure the sealing of the reagent bottle 10 when the sampling needle 12 is not inserted, and the anti-leakage component is used to prevent leakage of reagents during sampling.

[0022] As an implementation method in this embodiment, Figure 1 and Figure 2 As shown, the auxiliary sealing assembly includes a sealing ball 20 preset at the port of the reagent bottle 10, and a through hole 21 vertically penetrates the sealing ball 20. A rotating rod 22 is fixedly connected to one side of the sealing ball 20. The rotating rod 22 penetrates the sealing cover 11 horizontally, and the rotating rod 22 is rotatably connected to the sealing cover 11 through a sealing bearing. The end of the rotating rod 22 away from the sealing ball 20 is fixedly connected to a knob 23. During specific use, the rotating rod 22 is rotated by manually rotating the knob 23, and the rotating rod 22 drives the sealing ball 20 to rotate synchronously. The through hole 21 of the sealing ball 20 is vertically upward, so that the through hole 21 in the sealing ball 20 is connected to the inside of the reagent bottle 10, so as to facilitate the sampling needle 12 to be inserted into the reagent bottle 10 to extract reagents. The arrangement of this structure enables the sampling needle 12 to perform a sealing operation on the reagent bottle 10 when it is not inserted.

[0023] As an implementation method in this embodiment, Figure 3 and Figure 4 As shown, the leakage prevention component includes a pad 30 fixedly sleeved on the top outer wall of the sealing cover 11, a sealing groove 31 is opened on the upper end surface of the pad 30, a top cover 32 is arranged above the pad 30, and a sealing gasket 33 adapted to the sealing groove 31 is bonded and fixed to the lower end surface of the top cover 32. During specific use, the sealing operation is performed by the provided pad 30 and the top cover 32. When the sampling needle 12 is inserted, the top cover 32 is always located on the pad 30 by manual pressing, and the internal sealing effect is ensured by the provided sealing gasket 33 and the sealing groove 31.

[0024] As an implementation method in this embodiment, Figure 3As shown, the sampling needle 12 vertically passes through the center of the top cover 32, and the top cover 32 slides on the outer wall of the sampling needle 12 to avoid being blocked by the top cover 32 when the sampling needle 12 is extended into the sealed bottle. The sampling needle 12 can shuttle up and down in the center of the top cover 32, and a hole is preset in the center of the top cover 32 for the sampling needle 12 to be inserted.

[0025] As an implementation method in this embodiment, Figure 1 As shown, a positioning hole 231 is opened on the side wall of the knob 23 away from the rotating rod 22, and a positioning sticker 111 is fixed to the outer wall of the sealing cover 11. The positioning hole 231 and the positioning sticker 111 can be used as a visual mark to help the user understand the current position of the knob 23. When the knob 23 is rotated to the position where the through hole 21 is fully opened, the positioning hole 231 is aligned with the positioning sticker 111, thereby providing a clear instruction to the user.

[0026] The sealing sheet 13 is made of nitrile rubber material. When the sampling needle 12 is inserted into the reagent bottle 10, the end of the sealing sheet 13 away from the inner wall of the sealing cover 11 will bend, and a certain gap will appear during the bending process, so that the sampling needle can be inserted.

[0027] As an implementation method in this embodiment, Figure 1 As shown, a plurality of anti-skid rings 14 are fixed in an array on the outer wall of the sealing cover 11 , and the anti-skid rings 14 provide a sealing effect for the sealing cover 11 , thereby facilitating the user to rotate the sealing cover 11 .

[0028] Working principle: When in use, the knob 23 is manually rotated to rotate the rotating rod 22, and the rotating rod 22 drives the sealing ball 20 to rotate synchronously. The through hole 21 of the sealing ball 20 is vertically upward, so that the through hole 21 in the sealing ball 20 is connected with the inside of the reagent bottle 10. When the sampling needle 12 is inserted, the end of the sealing sheet 13 away from the inner wall of the sealing cover 11 will bend, and a certain gap will appear during the bending process, so that the sampling needle can be inserted. The top cover 32 is always located on the pad 30 by manual pressing, and the internal sealing effect is ensured by the provided sealing gasket 33 and sealing groove 31.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
