Flask frame for chemical experiments

Abstract

The invention discloses a flask holder for chemical experiments, which comprises a base, a ring body is fixed on the base, a vertical plate is fixed in the middle of the ring body, a ring groove is arranged on the ring body, and a T-shaped block is slidably connected in the ring groove. A threaded rod is fixed on the block, a butterfly nut is threaded on the threaded rod, a vertical rod is fixed on the threaded rod, a sleeve is slidably connected on the vertical rod, a stop is fixed on the lower end of the vertical rod, and a cross rod is fixed on the sleeve. A clip is fixed on the horizontal bar, a sponge layer is fixed in the clip, a disc is rotatably connected to the lower end of the vertical plate, a rotating rod is fixed on the disc, a ring body is fixed on the rotating rod, and asbestos net is fixed in the middle of the ring body, threaded rod and A connecting rod is fixed in the middle of the rotating rod, a cylinder is fixed at the side end of the base, a sliding rod is inserted into the cylinder, and a horizontal plate is fixed on the sliding rod. The height of the clip can be adjusted by the sleeve, which is suitable for various types of flasks. , It is more stable when pouring, easy to operate and save experimental time.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a flask rack for chemical experiments. Background technique [0002] Chemistry is a kind of natural science, which promotes the development and progress of human beings. Chemical experiments are an essential and important step in research. Flasks are often used in experiments to heat and react various experimental supplies. Flasks are usually placed on iron For heating and reaction on the stand, use flask clamps, crucible clamps and other clamping devices to remove after heating, and then pour the experimental liquid into the beaker. Stable or the flask is hot after heating, causing the liquid to spill, or scalding the arm, which is more dangerous, and it is inconvenient to use and the pouring speed is slower. Contents of the invention [0003] In order to solve the above existing problems, the present invention provides a flask rack for chemical experiments. [0004] The present inv...
