Double-seater desk and chair with steel angle frame structures

Abstract

The invention discloses a double-seater desk and a chair, which are provided with steel angle frame structures and used by students in various schools. In the invention, angle iron (iron) material is used for welding frameworks of the desk and the chair, face plates, bottom plates and side pates are fixed on the frameworks through bolts, and steel angle (iron) structure frameworks are used for replacing wooden frameworks, so that the desk and the chair are enabled to be firm and durable, leg breaking and falling to pieces are prevented, and the steel angle (iron) structure frameworks can be recycled, which is beneficial to forest resource protection. The heights of the double-seater desk and the chair can be adjusted flexibly so as to meet the requirements of students with different body forms.
