Lifting and pulling type biological sample displaying container

Abstract

The invention discloses a lifting and pulling type biological sample displaying container which is characterized in that a lifting and pulling mechanism is placed in a central through hole of a sealing cover, the lower end of an inner sleeve is connected with the central through hole of the sealing cover, and the upper end of a vertical guide column penetrating through the inner sleeve is fixedly connected with the upper end of an outer sleeve. A thread is placed inside the outer sleeve with the sealed upper end, and is meshed with a thread on the exterior of the inner sleeve, and an oil seal pipe is arranged on the exterior of the outer sleeve in a sleeved mode, wherein a gap exists between the outer sleeve and the oil seal pipe. The lower end of the oil seal pipe is fixedly connected with the inner sleeve, and an oiling opening is formed on the upper portion of the oil seal pipe. The lower end of the guide column is arranged inside a cylinder body and is connected with a net frame, an upper ring and a lower ring of the net frame are connected through 2-4 vertical support rods to form a support, and the lower ring is arranged on the bottom of the cylinder body. A bottom net connected with the lower ring is placed inside the cylinder body. 3-4 upper supports are evenly distributed on the upper ring, one ends of the upper supports are fixedly connected with the upper ring, and the other ends of the upper supports are movably connected with the lower end of the guide column. According to the lifting and pulling type biological sample displaying container, the cylinder body is sealed tightly without leakage, specimen cannot be oxidized, so that the specimen immersed in preservative liquid can be watched, and the specimen can be rotated and lifted to the liquid surface to be watched.

Description

technical field [0001] The invention relates to a biological sample storage and display device, in particular to a biological sample display container used for biology teaching and experimental research. Background technique [0002] At present, in the process of biology teaching and research, it is necessary to make and display various biological specimens. In order to preserve biological specimens for a long time, the biological specimens are generally put into transparent glass bottles, soaked in 5-10% formalin, or glacial acetic acid and copper sulfate and other antiseptic solutions, and the bottle caps are sealed with paraffin. Since students and researchers need to see through the antiseptic liquid layer in the glass to observe the specimens in the bottle, it is easy to cause distortion of the observed specimens, and the specimens in the bottle cannot be rotated, let alone when they are out of the antiseptic liquid surface. Viewing from below, it is very inconvenient ...

Since students and researchers need to see through the antiseptic liquid layer in the glass to observe the specimens in the bottle, it is easy to cause distortion of the observed specimens, and the specimens in the bottle cannot be rotated, let alone when they are out of the antiseptic liquid surface. Viewing from below, so it is very inconvenient to observe the details of the specimen
