Abstract

The invention discloses a chemical experiment table capable of automatically extinguishing fire, which comprises a table top, a base is fixedly connected to the bottom of the table top, a plurality of storage tanks are opened on the table top, and a linkage mechanism is arranged in the storage tanks. The linkage mechanism includes an insulating block and a connecting shaft, the connecting shaft is fixedly connected to the bottom of the insulating block, a copper plate is installed in the insulating block, a primary memory metal is fixedly connected to the inner wall of the storage tank, and the two ends of the copper plate All offset with the first-level memory metal. In the present invention, when the combustion spreads to the inside of the storage tank, the secondary memory metal inside the storage tank is heated and stretched, and when the secondary memory metal stretches, it presses against the U-shaped shaft and pulls the insulating block into the storage tank. All combustion requires the participation of oxygen, and if the air is isolated, that is, oxygen is isolated, and the oxygen in the storage tank is exhausted, the burning flame will be extinguished, so as to realize the collection of liquid and the extinguishment of the fire.

Description

technical field

[0001] The invention relates to the technical field of experiment tables, in particular to a chemical experiment table capable of automatically extinguishing fire. Background technique

[0002] Regardless of junior high school, high school or university, verification tests and experiments need to be carried out on the laboratory table, especially chemical experiments. Various chemical reagents are used in chemical experiments. Heating reaction conditions are common in chemical reactions. Laboratory It is a place for learning experiments, where heating is generally carried out by means of alcohol lamp heating, and each experimental table will be equipped with an alcohol lamp.

[0003] During the experiment, there is a large amount of alcohol accumulated inside the alcohol lamp. There are many uncertain factors in the experiment process. Any experiment needs to ensure the safety of students. Alcohol lamps are flammable and dangerous items. If accidentally bump...
