Abstract

The invention provides an automatic cover flipping structure of a micro-centrifugal tube. By the automatic cover flipping structure, a cover can be opened conveniently, and time and labor are saved. The automatic cover flipping structure comprises the cover and a tube body, wherein the cover is arranged on the inner wall of an orifice of the tube body in a covering manner, an outer-edge annular surface of the cover clings to the inner wall of the orifice in an interference fit manner, and a connecting portion of the cover is arranged at a connecting end of the tube body by a hinge pin. The automatic cover flipping structure is characterized in that an outer-edge positioning bump is arranged on an outer-edge annular surface of the orifice, the cover is provided with a latch arranged at a position corresponding to the outer-edge positioning bump, the latch fastens the lower end surface of the outer-edge positioning bump when in a locking state, and two upward convex structures are arranged on portions of the connecting end of the tube body close to the orifice, are abutted to lower end surfaces of corresponding positions of the connecting portion of the cover when in locking states, and are of high-elasticity material structures.

Description

technical field [0001] The invention relates to the technical field of cell culture devices, in particular to a structure for automatically flipping a cover of a microcentrifuge tube. Background technique [0002] A microcentrifuge tube is a small centrifuge tube, which is used in conjunction with a microcentrifuge for the separation and centrifugation of micro reagents. It is widely used in biological sciences, especially in the fields of biochemistry and molecular biology. [0003] In the existing microcentrifuge tube structure, the lid and the mouth of the tube adopt an interference fit method. When opening the lid, the lid needs to be manually pulled out from the mouth of the tube body, which takes time and effort and delays time. Contents of the invention [0004] In view of the above problems, the present invention provides a structure for automatically flipping the cover of the microcentrifuge tube, which makes the opening of the cover convenient, saves time and eff...
