Chemical-experiment protecting cover with safety protection function

Abstract

The invention provides a chemical-experiment protecting cover with a safety protection function. The chemical-experiment protecting cover comprises a supporting base and a transparent outer cover, wherein the transparent outer cover is located at the upper position of the supporting base; further, the transparent outer cover is closely abutted with the supporting base; a temperature measuring strip is embedded in the right lower position of the front end of the transparent outer cover; further, a rotating column is embedded in the upper part of the front end of the transparent outer cover; a movable magnetic plate is fixedly arranged at the lower part of the rotating column; further, two sides of the movable magnetic plate are magnetically connected with magnetic borders; a pull rod is embedded into the middle position of the bottom of the front end of the movable magnetic plate. In the device, through setting the components of the movable magnetic plate and the magnetic borders, the pull rod is grasped by hand to open the movable magnetic plate in a front-rear manner through the rotating column; the placement of a medicine and an agent is carried out; afterwards, due to the magnetic attraction principle of the movable magnetic plate and the magnetic borders, the movable magnetic plate is perfectly tallied with the magnetic borders; the influence on the implementation of an internal chemical experiment is prevented, and the chemical-experiment protecting cover is applicable to the production and use in the field of protecting covers, and has a favorable development prospect.

Description

technical field [0001] The invention relates to the technical field of protective covers, in particular to a chemical experiment protective cover. Background technique [0002] The protective cover can strictly prevent dust, chips, hard sand, etc. It should be smooth without burrs and sharp edges and corners, and should not become a new source of danger; and the protective cover should not affect the line of sight and normal operation, and should be convenient for equipment inspection and maintenance. With the development of science, the number of protective covers for chemical experiments will also increase. , and the function is getting more and more powerful. [0003] An existing protective cover for chemical experiments cannot conveniently adjust the state of ventilation and sealing in chemical experiments, resulting in the inability to carry out some experiments that require air, and some materials need to be added in the middle of the experiment, requiring the entire ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the technical problems that it is impossible to conveniently adjust the state of ventilation and sealing, some materials need to be added in the middle, the entire protective cover needs to be lifted and placed, the operation is troublesome, and the structure is simple, so as to provide a safety protection function. Chemical experiment protection cover, the device is equipped with movable magnetic plate and magnetic frame parts, so that the movable magnetic plate fits perfectly with the magnetic frame to prevent the internal chemical experiment from being affected. The existing protective cover cannot conveniently adjust the state of ventilation and sealing. Some materials need to be added in the middle, and the entire protective cover needs to be lifted and placed. The operation is troublesome and the structure is simple.
