High school bioexperiment test tube cleaning and clamping device

Abstract

The invention discloses a high school biological test tube cleaning and clamping device. The device comprises an experimental table top, wherein a fixing shell is arranged above the experimental tabletop; a lifting screw rod is arranged in the fixing shell; the upper end of the lifting screw rod is connected with a motor output end arranged on the upper surface of the fixing shell; a control switch is arranged on one side of the fixing shell; a lifting block is arranged on the outer side surface of the lifting screw rod; one side of the lifting block is fixedly connected with a fixing table through a first connecting rod; test tube holes where test tubes penetrate are formed in the fixing table; arc-shaped clamping plates are symmetrically arranged at the left end and the right end of theouter side surface of the upper end of each test tube; the arc-shaped clamping plates are fixedly connected with sliding blocks through second connecting rods; the sliding blocks are slidably connected in chutes; and the chutes are symmetrically formed in the two sides of an arc-shaped sliding rail. According to the device, the clamping force on the test tubes is controllable, so that the test tubes are protected from being damaged; and the clamping is adjustable according to different outer diameters of the test tubes, so that the clamping is firmer, and the use safety is much higher.

Description

technical field [0001] The invention relates to the technical field of biological experiments, in particular to a cleaning and clamping device for high school biological experiment test tubes. Background technique [0002] The high school study stage involves a variety of biological experiments. When detecting sugars, fats and proteins in biological tissues, some chemical agents are needed for color reaction detection, and these chemical agents need to be contained in test tubes. [0003] When the experiment is finished, the test tube needs to be cleaned. Usually, the mouth of the test tube is facing down and then cleaned through the water pipe. When the clamp is clamped, it is not easy for a single person to control the force and easily cause damage to the test tube. At the same time, the size of the outer diameter of the test tube The difference is that it is easy to loosen when clamped with a clip, causing the test tube to fall off, which is very unsafe.
