A three-necked flask scrubbing device with directional control of cleaning range

Abstract

The invention provides a three-necked flask scrubbing device and method with the directional control of a cleaning range, and relates to the field of chemical instrument cleaning. The three-necked flask scrubbing device and method with the directional control of the cleaning range solve the problem that the inner wall of a three-necked flask is not easy to clean completely, and the existence of more cleaning dead corners affects the accuracy of the experiment. The three-necked flask scrubbing device with the directional control of the cleaning range comprises a sheathed fixed cylinder, whereinan opposite friction fixed mechanism is sheathed on the exterior of the sheathed fixed cylinder; the top of the sheathed fixed cylinder is movably connected to the bottom of a lifting and rotating mechanism through a top side bearing; the upward side of the sheathed fixed cylinder is connected to a fixed clamp cylinder through the lifting and rotating mechanism; and a telescopic elastic ring is arranged under the sheathed fixed cylinder. According to the three-necked flask scrubbing device with the directional control of the cleaning range, a lifting stud can be controlled to rotate and liftinside the fixed clamp cylinder by rotating a rotary grip, and an inner side telescopic supporting rod is driven to move up and down through an inner side bearing, so that the vertical angle of a bentbottom rod movably arranged at the bottom of an outer arc spring plate is changed so as to facilitate the comprehensive cleaning of the inner wall of the flask.

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.
