Soft protective cushion for student desk and chair

Abstract

The invention discloses a soft protective cushion for a student desk and chair. The soft protective cushion comprises a student desk face plate, a chair plate, a chair back plate and chair legs, and is characterized in that a foaming polyurethane outer layer is respectively arranged outside the student desk face plate, the chair plate and the chair back plate which are made of wood. When the soft protective cushion is manufactured, the student desk face plate, the chair plate, the chair back plate and the chair legs are manufactured firstly as prefabricating pieces, then the prefabricating pieces are put into a mould, and polyurethane foaming agent is injected into the mould to enable the foaming polyurethane outer layer to be formed on the surface of each prefabricating piece. The foaming polyurethane outer layers are nontoxic, and have no harm when a human body contacts, the service life of foaming polyurethane is long, the surface is smooth, and the strength is excellent. After the surfaces of the student desk and chair are provided with the foaming polyurethane outer layers with the same color, the product level is increased, and the environment of a classroom is changed.

Description

technical field [0001] The invention relates to desks and chairs for students, in particular to soft protective pads for desks and chairs for students. Background technique [0002] Traditional student desks and stools (chairs) are made of solid wood materials, which are hygienic and environmentally friendly, and light in weight. However, due to the shortage of wood resources, troublesome processing, high cost, and relatively clumsy and other shortcomings, most of them now Use the combination of steel and wood, or steel and plastic to process student desks and chairs. Steel-wood desks and chairs are suitable for machining, easy to assemble and disassemble, and reduce transportation volume. However, the existing student desks and chairs generally have simple structures and low product grades. Steel-wood chairs are hard to sit in summer and cold in winter. Foreign objects touch the back of the chair, chair legs and tables, and the paint on the surface of the steel parts is eas...

[0002] Traditional student desks and stools (chairs) are made of solid wood materials, which are hygienic and environmentally friendly, and light in weight. However, due to the shortage of wood resources, troublesome processing, high cost, and relatively clumsy and other shortcomings, most of them now Use the combination of steel and wood, or steel and plastic to process student desks and chairs. Steel-wood desks and chairs are suitable for machining, easy to assemble and disassemble, and reduce transportation volume

However, the existing student desks and chairs generally have simple structures and low product grades. Steel-wood chairs are hard to sit in summer and cold in winter. Foreign objects touch the back of the chair, chair legs and tables, and the paint on the surface of the steel parts is easily damaged. , falling off, causing rust, the surface of the wooden tabletop and chair (stool) is easy to crack or be scratched by foreign objects, which affects the writing and sitting effect
