Oscillation type test tube cleaning device

Abstract

The invention discloses an oscillation type test tube cleaning device which comprises a supporting sleeve and a rotating rod body located in the supporting sleeve, the axis of the supporting sleeve coincides with the axis of the rotating rod body, a first fixing piece and a second fixing piece are arranged at the bottom end of the supporting sleeve, and a preset distance is reserved between the first fixing piece and the second fixing piece in the direction of the supporting sleeve. A cleaning piece is movably arranged on the edge of the second fixing piece, a pulling mechanism is arranged between the first fixing piece and the cleaning piece, and the pulling mechanism can pull the cleaning piece to swing up and down. The pulling mechanism comprises a polarization ring, an ejector head, a pull rod, a sliding seat and a mounting seat, the polarization ring is fixed to the rotating rod body and located in the first fixing piece, and the ejector head is arranged in an ejector head sliding cavity in the first fixing piece in a sliding mode. The cleaning effect can be improved, and waste liquid is prevented from remaining on the inner wall of the test tube; the cleaning efficiency is improved, and the cleaning operation time is shortened.

Description

technical field [0001] The invention relates to the technical field of test tube cleaning, in particular to an oscillating test tube cleaning device. Background technique [0002] A test tube is a common container for chemical reactions with a small amount of reagents, and is mainly used in pharmaceutical research and chemical laboratories. The test tube can be used in both normal temperature and heating environments. If heating is required, the test tube needs to be preheated before heating, so that the test tube can be heated evenly and used safely. There are also many types and specifications of test tubes. Specifically, they can be divided into ordinary test tubes, support test tubes, and centrifuge test tubes. [0003] On the other hand, some common combustion experiments can be carried out in test tubes, such as potassium permanganate heating to oxygen production, red phosphorus combustion and other experiments. During the experiment, the burning chemical reagents fo...

Problems solved by technology

[0005] The purpose of the present invention is to provide an oscillating test tube cleaning device. When the present invention is used, the support sleeve is first fixed on the driving part, and then the rotating rod body is connected with the output shaft of the driving part, and the output shaft of the driving part rotates to drive the rotating rod body. Rotating, the rotating rod drives the cleaning sheet to swing back and forth through the pulling mechanism to clean the inner wall of the test tube, so as to solve the incomplete cleaning of massive particle attachments and the existence of attachment residues; manual cleaning has certain safety hazards; the operation efficiency is low, and the cleaning of the inner wall of the test tube is prolonged. question of time required
