Abstract

The utility model provides a folding iron support for chemical teaching and belongs to the field of chemical teaching devices. The folding iron support structurally comprises a base, a bracket, an iron clamp and an iron ring, wherein the bracket is divided into an upper bracket, a middle bracket and a lower bracket; the lengths of the upper bracket, the middle bracket and the lower bracket are the same; the right side of the lower end of the upper bracket is articulated with the right side of the upper end of the middle bracket; the left side of the lower end of the middle bracket is articulated with the left side of the upper end of the lower bracket; a location knob in threaded connection with the upper bracket is arranged at the upper end of the upper bracket; a pedestal is arranged at the lower end of the lower bracket; the lower end of the lower bracket is articulated with the upper end of the pedestal; location blocks are arranged at the lower end of the lower bracket; the pedestal is articulated with the base; and correspondingly, a bracket placement groove and an iron ring placement groove are formed in the base. Compared with the prior art, the support has the characteristics of reasonable design, simple structure, good use effect and the like.

Description

A kind of chemistry teaching folding iron pallet

Technical field

The utility model relates to chemistry teaching device field, specifically a kind of chemistry teaching folding iron pallet.

Background technology

In the chemistry subject teaching, often need to use iron stand to carry out chemical experiment, requirement according to State Education Commission's 1993 " the middle school science instruments used for education are equipped with catalogue ", one class senior middle school must be equipped with the J1102 sections pallet of the above traditional structure of 122 cover, " whole nation demonstration senior middle school " should be equipped with the above J1102 sections of 244 cover pallet, and the demand of iron stand in teaching is very big as can be seen here.The iron stand used at present consists of iron base, support, iron ring, iron clamp, and support vertical is fixed on the upper face rear side of iron base, can not fold, and be connected with base, carries extremely inconvenient.

Summary of the invention
