Teaching equipment with high safety for experiments

Abstract

The invention discloses teaching equipment with high safety for experiments. The teaching equipment comprises a support frame, a bottom plate and a protection frame, wherein two sides of the top of the inner wall of the support frame are fixedly connected with fixing blocks; the bottom of each of the two fixing blocks penetrates through the protection frame and extends to the inside of the protection frame; the teaching equipment relates to the technical field of teaching facilities. The teaching equipment with high safety for experiments has the advantages that grooves matched with moving rods are formed in one side, deviated from the two fixing blocks; the danger caused by test tube fracture is prevented; the risk is reduced; the experiment safety is improved; position limiting holes areformed in the top of the fixing plate; one end of each of two second springs is fixedly connected with a first connecting plate; an installing groove is formed inside the protection frame; two sidesof the bottom of the inner wall of the installing groove are fixedly connected with third springs, so that a buffer effect can be achieved on test tubes; the fracture caused by collision between the test tube wall and the fixing plate is prevented; the protection frame can be dismounted; the cleaning is convenient.

Description

technical field [0001] The invention relates to the technical field of teaching facilities, in particular to a safe experimental teaching equipment. Background technique [0002] The equipment used to facilitate teaching in teaching activities. The hardware facilities in teaching facilities often include: the size of the school, the number of classrooms, the size of the playground, the size of the activity center, whether the machinery, simple medical equipment, and sports equipment are complete, etc., hardware facilities It is closely related to the teaching scale of the school. The software facilities in the teaching facilities often include: whether the teaching staff is strong, whether the logistics service is satisfactory, whether the teaching management is strict and standardized, whether the living and accommodation are warm, whether the school teaching environment is reasonable, etc. The software facilities of the school have a very important relationship with the pr...
