Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected" and "disposed" are to be construed broadly, and may for example be fixedly connected, disposed, detachably connected, disposed, or integrally connected and disposed. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in FIGS. 1 and 2, the cell culture apparatus for biotechnology of the present invention comprises a culture test tube 7, wherein a first internal thread is provided on an outer wall surface of an opening at an upper end of the culture test tube 7, a cover 5 covering the opening is installed on the opening at the upper end of the culture test tube 7, a first external thread is provided on an inner wall surface of the cover 5, the first external thread on the cover 5 is engaged with the first internal thread on the culture test tube 4, a piston 4 is fixed to an inner top surface of the cover 5, a lower end of the piston 4 is inserted into the opening of the culture test tube 7 and abuts against the inner wall surface of the opening, more than one screw holes are provided on the top surface of the cover 5, the more than one screw holes are uniformly distributed in a ring structure, a through hole penetrating through the screw holes is provided right at the screw holes for the piston 4, a tube body 3 communicating up and down is screwed in the screw holes, a sealing plug, a rotating ring 1 is mounted on the top surface of the sealing plug 2.

In this embodiment, a section of the tube 3 inside the piston 4 is abutted against an inner wall surface of the through hole, an opening at the lower end of the tube 3 is outwardly expanded to form an expanded portion 6, and a rubber ring 8 is adhered and fixed on the bottom surface of the expanded portion 6.

In this embodiment, the inside bottom surface of culture tube 7 is parallel structure setting for the rubber circle can offset with the bottom surface.

In this embodiment, the piston 4 is made of rubber material, which increases the sealing performance between the piston and the culture tube and the tube body.
