Iron stand for chemical experiments

Abstract

The invention relates to the technical field of chemical experiment equipment, in particular to an iron stand for chemical experiment. The iron stand comprises a vertical rod, a fixing device and a base, wherein the vertical rod is vertically arranged above the base, a ring is fixedly on the surface of the vertical rod, and the fixing device comprises a first fixing device, a second fixing device and a third fixing device, a ferrule and an installation piece are arranged on the contact parts of the first fixing device, the second fixing device and the third fixing device with the vertical rod, the installation piece is arranged at one end of the ferrule, and the first fixing device is provided with a connecting rod and a fixing clamp, the end of the fixing clamp is provided with a fixed plate shaped like a Chinese character 'mi', and one end of the connecting rod is provided with a groove shaped like a Chinese character 'mi'. The iron stand can fix the fixing clamp firmly, the fixing clamp on the iron stand does not fall from the rod; a test tube which needs to be tilted and fixed is relatively firm, and the tilt angle of the test tube is relatively simple and quick to adjust; the iron stand is fixed on the fixing ring, and fire hazard due to knocking over by people can be prevented.

Description

technical field [0001] The invention relates to the technical field of chemical experiment equipment, in particular to an iron stand for chemical experiments. Background technique [0002] The iron stand is used to fix and support various instruments, and the iron ring can be used instead of the funnel stand. It is generally used in experimental operations such as filtration, heating, and titration. It is one of the most widely used instruments in physics and chemistry experiments. Often used in conjunction with alcohol lamps. The iron stand is a common experimental equipment, which can be expanded by tools such as fixing clips or universal clips to support experimental equipment such as test tubes and burettes. The iron stand can also be combined with the iron ring for filtration. A typical iron stand length is 0.5 meters, which is sufficient for most experiments and is more suitable for operation in a fume hood. If a higher iron rod is required, the ordinary stainless...

AI Technical Summary

Problems solved by technology

[0004] 1. The fixation of the fixing clip is not firm. When in use, the fixing clip on the iron stand will slip off the iron rod

[0005] 2. The test tubes that need to be fixed at an angle are not fixed firmly, and the adjustment of the inclination angle of the test tube is cumbersome

[0006] 3. The alcohol lamp is placed on the base of the iron stand, it is easy to be knocked over, and it is easy to cause a fire
