DETAILED DESCRIPTION

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0018] Embodiments of the present utility model: Figure 1-Figure 3 As shown, an extraction bottle with an automatic opening and closing structure includes an extraction bottle body 1, a bottle cap 2 and a pressing device 13. A sealing structure is provided at the bottom of the bottle cap 2, and a connecting plate 3 is formed on one side of the bottle cap 2. The telescopic end of the pressing device 13 abuts against the top surface of the connecting plate 3, and the connecting plate 3 is connected to the extraction bottle body 1 through an elastic connecting component.

[0019] The sealing device at the bottom of the bottle cap 2 is used to seal the top of the extraction bottle body 1 to prevent the reagent from spilling during the oscillation extraction process. The pressing device 13 is used to provide downward pressure to the connecting plate 3 to open the bottle cap 2, and the closing of the bottle cap 2 is achieved by the elastic connecting component.

[0020] In a specific embodiment, the elastic connection assembly includes a support rod 4, a connecting rod 5 and a torsion spring 6. There are two support rods 4. The lower ends of the two support rods 4 are fixedly connected to the outer wall of the extraction bottle body 1. The upper ends of the two support rods 4 are provided with a first mounting hole 7, and a rotating shaft 8 is installed in the first mounting hole 7. The upper end of the connecting rod 5 is fixedly connected to the bottom surface of the connecting plate 3, and the lower end of the connecting rod 5 is provided with a second mounting hole 9. The rotating shaft 8 passes through the second mounting hole 9, and two torsion springs 6 are installed on the rotating shaft 8.

[0021] Both ends of the rotating shaft 8 are interference fit with the first mounting holes 7 on the two support rods 4. In this embodiment, preferably, a bearing is provided in the second mounting hole 9 on the connecting rod 5, the outer ring of the bearing is interference fit with the second mounting hole 9, and the inner ring of the bearing is interference fit with the rotating shaft 8. The bearing is not shown in the figure. The setting of the bearing can not only make the connecting rod 5 rotate smoothly around the rotating shaft 8, but also prevent the connecting rod 5 from axial movement.

[0022] Further, two torsion springs 6 are symmetrically arranged on both sides of the connecting rod 5, a first L-shaped limit rod 10 is formed on both side walls of the connecting rod 5, and a second L-shaped limit rod 11 is formed on the opposite side walls of the two support rods 4, one end of the torsion spring 6 is connected to the first L-shaped limit rod 10 by clamping, and the other end of the torsion spring 6 is connected to the second L-shaped limit rod 11 by clamping. The two torsion springs 6 are used to provide a rebound force for the connecting rod 5, so that the bottle cap 2 can automatically cover the extraction bottle body 1.

[0023] Furthermore, a guide groove 12 is formed on the top surface of the connecting plate 3 , and the pressing device 13 is a cylinder or an electric push-pull rod. The telescopic end of the pressing device 13 has a spherical end 14 , and the spherical end 14 is slidably matched with the guide groove 12 .

[0024] The guide groove 12 is arranged on the symmetric axis of the connecting plate 3. The guide groove 12 can make the spherical end 14 on the pressing device 13 slide in the guide groove 12, so as to prevent the axial position of the connecting plate 3 from deviating when pressure is applied, thereby ensuring that the bottle cap 2 can be aligned with the extraction bottle body 1 and covered when it returns.

[0025] Furthermore, the sealing structure includes an inner sealing ring 15, the outer diameter of which gradually increases from bottom to top, the outer diameter of the lower end of the inner sealing ring 15 is smaller than the inner diameter of the extraction bottle body 1, and the outer diameter of the top end of the inner sealing ring 15 is 1 mm larger than the inner diameter of the extraction bottle body 1. Such a design can make the lower end of the inner sealing ring 15 accurately inserted into the extraction bottle body 1 and effectively seal the extraction bottle body 1. The sealing structure also includes an outer sealing ring 16, which is coaxial with the inner sealing ring 15, and the inner diameter of the outer sealing ring 16 gradually decreases from bottom to top, the inner diameter of the lower end of the outer sealing ring 16 is larger than the outer diameter of the extraction bottle body 1, and the inner diameter of the top end of the outer sealing ring 16 is 1 mm smaller than the outer diameter of the extraction bottle body 1. Such a structural design can also make the outer sealing ring 16 effectively sleeved on the extraction bottle body 1 and effectively seal the extraction bottle body 1. In this embodiment, the inner sealing ring 15 and the outer sealing ring 16 are both made of rubber.

[0026] The working principle of the utility model is as follows: when the bottle cap 2 needs to be opened, the pressing device 13 is extended, and the spherical end 14 thereon is lowered and abutted against the guide groove 12. As the pressing device 13 is extended, the end of the connecting plate 3 away from the extraction bottle body 1 is pressed down, and the connecting plate 3 rotates around the rotating shaft 8 with the bottle cap 2, so that the bottle cap 2 is separated from the extraction bottle body 1, and the bottle cap 2 is opened. When the bottle cap 2 needs to be closed, the pressing device 13 is contracted, and the downward pressure disappears. Under the elastic force of the two torsion springs 6, the bottle cap 2 and the connecting plate 3 quickly return to their positions, and the bottle mouth of the extraction bottle body 1 is sealed by the inner sealing ring 15 and the outer sealing ring 16.

[0027] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
