Abstract

The invention discloses a middle school chemistry teaching instrument cleaning device. The device comprises a bracket, a fixing mechanism for fixing test tubes, a conveying mechanism for conveying thetest tubes, and a cleaning mechanism for cleaning the test tubes; the fixing mechanism comprises a positioning base, a bolt and a fixing bar; a positioning hole for positioning the test tube is formed in the top of the positioning base; the bolt is in threaded connection with a thread hole after penetrating through a connecting hole to shrink the fixing bar as an annular structure; the test tubesare fixed in the annular structure; the cleaning mechanism comprises a cleaning frame, a cylinder, a brush motor and a brush; the cleaning frame is arranged on one side of the bracket; the cylinder is arranged on the cleaning frame and positioned above the positioning base; the brush motor is fixed on a pushing rod of the cylinder; the brush is fixed on a rotating shaft of the brush motor; and the brush motor drives the brush to rotate. Through the arrangement, the test tubes are automatically brushed, liquid in the test tubes is prevented from splashing during brushing to injure the health of students, and the injury probability of the students by chemical reagents is reduced.

Description

technical field [0001] The present invention relates to a kind of experimental equipment, more specifically relates to a kind of middle school chemistry teaching instrument cleaning device. Background technique [0002] At present, test tubes are widely used in chemical laboratories in middle schools. Test tubes can be directly heated and used as reaction containers for a small amount of reagents. After the experiment is over, the test tube needs to be cleaned after the waste liquid in the test tube is poured out. [0003] However, the chemical reagents remaining in the test tubes are easy to splash when cleaning, which is harmful to the health of students. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a middle school chemistry teaching instrument cleaning device, which can automatically clean test tubes and reduce the chance of students being injured by chemical reagents. [0005] In or...
