Three-opening flask washing device with cleaning range capable of being directionally controlled

Abstract

The invention provides a three-opening flask washing device with cleaning range capable of being directionally controlled, and relates to the field of chemical instrument cleaning. The problems that the inner wall of a three-opening flask is not prone to comprehensive cleaning, multiple cleaning dead corners exist, and the experiment accuracy is affected are solved. The three-opening flask washingdevice with the cleaning range capable of being directionally controlled comprises a sleeving fixed cylinder, the outer portion of the sleeving fixed cylinder is sleeved with an opposite friction fixing mechanism, the top of the sleeving fixed cylinder is movably connected with the bottom of a lifting rotating mechanism through a top side bearing, the upper portion of the sleeving fixed cylinderis connected with a fixed clamping cylinder through the lifting rotating mechanism, and a telescopic elastic ring is arranged below the sleeving fixed cylinder. According to the three-opening flask washing device with the cleaning range capable of being directionally controlled, a rotating handle is rotated to control a lifting stud to rotatably ascend and descend in the fixed clamping cylinder, through an inner side bearing, an inner side telescopic abutting rod is driven to move up and down, a bending bottom rod movably arranged on the bottom of an outer arc elastic piece is changed in a vertical angle manner, and the inner wall of the flask can be conveniently and comprehensively cleaned.

Description

technical field [0001] The invention relates to the technical field of chemical instrument cleaning, in particular to a three-necked flask scrubbing device whose cleaning range can be directional-controlled. Background technique [0002] The three-necked flask will form dirt on its inner wall after use, and it is not easy to clean it with chemicals. The test tube brush used in the laboratory is straight, which is not convenient for cleaning the three-necked flask with curved walls. The application number is CN201320126858.3 A special brush for a three-necked flask, which can clean most of the inner wall of the three-necked flask, but the top of the inner wall of the three-necked flask cannot be cleaned because the straight connecting rod is blocked by the bottle mouth, and there is a cleaning dead angle, which affects the accuracy of the experiment sex. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, ...
