Test tube rack capable of regulating aperture and height for chemical engineering experiment

Abstract

The invention discloses a test tube rack capable of regulating an aperture and a height for a chemical engineering experiment. Set bolts adapting to threaded holes are arranged in the threaded holes; sliding chutes are arranged in the upper part of sliding chute plates; a test tube rack is arranged above the sliding chute plates; a left side and a right side below the test tube rack are both provided with sliding blocks; the sliding blocks are located in the sliding chutes; the front end surface of the test tube rack is provided with a motor; the motor is provided with a first screw rod; the first screw rod runs through the test tube rack from front to back; a test tube rack body consists of a first tube wall clamping block and a second tube wall clamping block. According to the test tube rack capable of regulating the aperture and the height for the chemical engineering experiment, the positions, in sleeve plates, of the sliding chute plates are regulated; afterwards, the sliding chute plates and the sleeve plates are connected through the set bolts; thus, the height of the test tube rack is changed; secondly, through utilizing the cooperation between a second screw rod and a nut, the positions of the first tube wall clamping block and the second tube wall clamping block are regulated, so as to clamp test tubes with different diameters.

Description

technical field [0001] The invention relates to the technical field of chemical experiments, in particular to a test tube support with adjustable aperture and height for chemical experiments. Background technique [0002] At present, the use height and aperture of the test tube racks used in general chemical laboratories are fixed, and can only be applied to test tubes of one diameter and height. Various test tubes need to be equipped with various test tube racks, which leads to the occupation of laboratory test tube racks. The space is large, the cost is high, and the resource utilization rate is low. Contents of the invention [0003] The object of the present invention is to provide a test tube holder with adjustable aperture and height for chemical experiments, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a test tube supp...
