[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] It should be noted that when a component is referred to as being "mounted on" another component, it may be mounted directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component. When a component is considered to be "fixed to" another component, it may be directly fixed to the other component or there may be a central component.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1 As shown, the drug sensitivity reagent bottle includes a tubular upper bottle 1 and a lower bottle 2. The upper bottle 1 has a hollow interior and an open lower end, and the lower bottle 2 has a hollow interior and an open upper end.

[0025] like Figure 1 and Figure 2 As shown, the connecting mechanism between the upper bottle and the lower bottle in the present drug sensitivity reagent bottle is located between the lower end of the upper bottle 1 and the upper end of the lower bottle 2, including a cylindrical connecting tube 3, the upper end of the connecting tube 3 has a snap-fit ​​structure, the upper end of the connecting tube 3 is embedded in the inner port of the lower end of the upper bottle 1 and the two are positioned and connected by the snap-fit ​​structure, the side wall of the connecting tube 3 has a concave-convex connecting portion 1, the inner side of the above-mentioned lower bottle 2 has a connecting portion 2a that matches the connecting portion 1, when the connecting portion 1 is matched and connected with the connecting portion 2 2a, the upper port of the above-mentioned lower bottle 2 abuts against the lower port of the upper bottle 1.

[0026] Since the upper end of the connecting tube 3 is connected to the inner side of the upper bottle 1 through the buckling structure, the lower end of the connecting tube 3 is connected to the inner side of the lower bottle 2 through the cooperation of the connecting part 1 and the connecting part 2a.

[0027] It can be seen that the connecting tube 3 can stably connect the upper bottle 1 and the lower bottle 2, and at the same time, the open end of the upper bottle 1 and the open end of the lower bottle 2 abut against each other to achieve sealing of the upper bottle 1 and the lower bottle 2.

[0028] The buckling structure includes a buckling edge 3a that is annularly protruding on the outer side of the upper end of the connecting tube 3, and an annularly concave buckling groove 1a is provided on the inner wall of the upper bottle 1, and the buckling edge 3b is embedded in the buckling groove 1a.

[0029] After the buckling edge 3b is inserted into the buckling groove 1a, the connecting tube 3 can be stably connected to the upper bottle 1.

[0030] The connecting tube 3 is made of a relatively flexible plastic material, which ensures that the connecting tube 3 has a certain strength and can also be deformed appropriately, thereby ensuring that the connecting tube 3 can be stably embedded in the upper bottle 1.

[0031] The first connecting portion is a connecting edge 3 b protruding in an annular shape on the outside of the connecting tube 3 . There are several connecting edges 3 b , which are adjacently arranged along the axis of the connecting tube 3 .

[0032] The arrangement of the plurality of connecting edges 3b enables the lower end of the connecting tube 3 to be stably positioned and connected to the lower bottle 2. Of course, after applying a relatively large external force, the upper bottle 1 and the lower bottle 2 can also be stably disassembled.

[0033] The outer diameter of the connecting edge 3b is smaller than the outer diameter of the locking edge 3a.

[0034] Such a structure can effectively distinguish the installation position of the connecting tube 3 and prevent the connecting portion from extending into the upper bottle.

[0035] The connecting tube 3, the buckling edge 3a and the connecting edge 3b are an integrated structure and are made of plastic material.

[0036] There is an elastic pre-tightening structure between the buckling edge 3a and the upper part of the buckling groove 1a, under the action of the elastic pre-tightening structure, the connecting tube 3 can move upward and drive the upper end of the lower bottle 2 to abut against the lower end of the upper bottle 1.

[0037] Under the action of the elastic pre-tightening structure, the upper bottle 1 port and the lower bottle 2 port can be stably pressed against each other.

[0038] The elastic pre-tightening structure includes an elastic washer 4 between the lower portion of the fastening edge 3a and the fastening groove 1a.

[0039] Since the gasket 4 is tightly pressed between the fastening edge 3a and the fastening groove 1a, the elastic force of the gasket 4 itself can make the connecting tube 3 tend to move upward. Since the connecting tube 3 is stably connected to the lower bottle 2, it can eventually drive the lower bottle 2 to move upward and have a tendency to rest against the upper bottle 1.

[0040] The lower portion of the buckling edge 3a has an annular concave positioning groove 3a1, and the upper side of the gasket 4 is embedded in the positioning groove 3a1.

[0041] The gasket 4 can be pre-positioned by the positioning groove 3a1, thereby improving the convenience during installation.

[0042] The lower part of the locking edge 3a is an inclined working surface 1 3b1, and the lower side of the locking groove 1a is a working surface 2 3a11 parallel to the working surface 1 3b1. The positioning groove 3a1 is located at the working surface 1 3b1, and the upper part of the gasket 4 is embedded in the positioning groove 3a1, and the lower part of the gasket 4 maintains surface contact with the working surface 2 3a11.

[0043] Such a structure enables the buckling edge 3a to be stably separated from the upper bottle 1.

[0044] The lower part of the locking edge 3a is an inclined working surface 1 3b1, and the lower side of the locking groove 1a is a working surface 2 3a11 parallel to the working surface 1 3b1. The positioning groove 3a1 is located at the working surface 2 3a11. The lower part of the washer 4 is embedded in the positioning groove 3a1, and the upper part of the washer 4 maintains surface contact with the working surface 1 3b1.

[0045] The connection mechanism of the upper bottle and the lower bottle in the drug sensitivity reagent bottle is connected by a connecting tube. Under the action of the snap-fit ​​structure, the connecting tube and the upper bottle are stably connected. After the first connecting part and the second connecting part cooperate, the connecting tube and the lower bottle can be stably connected. Obviously, under the action of the connecting tube, the upper bottle and the lower bottle can be stably connected together.

[0046] Since the connecting cylinder is located inside the upper bottle and the lower bottle, the connecting cylinder does not occupy additional space. The structure of the connecting mechanism is relatively compact and has high practical value.

[0047] The various technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] Those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present invention and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments fall within the scope of protection claimed by the present invention.
