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

Student's desk, chair soft protective pad

Technical field

The present invention relates to table, chair that the student uses, particularly relate to student's desk, chair soft protective pad.

Background technology

Traditional student's desk, stool (chair) adopt solid wood material made, have hygienic environment-protecting, weight is lighter, but because timber resources is more and more in short supply, and processing trouble, expense is high, the more native shortcoming such as stupid again, and majority is used steel and wooden combination instead now, the perhaps incompatible processing student's desk of steel and plastic tie, chair, steel wood desk, chair are applicable to machining, fill, tear open easily, reduce transportation volume.But existing student's desk, chair ubiquity simple in structure, product specification is low, steel wood chair is sat up very hard summer, winter is cold again, foreign matter is run into the chair back, chair pin and desk, and the paint of steel piece surface damages easily, comes off, and causes and gets rusty, the desktop of plank and chair (stool) face is easy to crack or scratched by foreign matter, has affected the effect of writing and be seated.

Summary of the invention

The objective of the invention is the shortcoming that exists in order to overcome prior art, provide a kind of surface at table, chair (stool) that soft sheath is arranged again, use comfortablely, soft, avoid the steel part painted surface to come off, the student's desk of external form elegance, chair soft protective pad.

The technical scheme of student's desk of the present invention, chair soft protective pad is: comprise desk panel, chair seat board, chair back plate and chair pin, it is characterized in that the skin that wooden desk panel, wooden chair seat board and wooden chair back plate all are shaped with polyurathamc outward.

Student's desk of the present invention, chair soft protective pad, the chair pin that described chair pin is metal is shaped with the skin of polyurathamc outside the chair pin of metal.

The present invention relates to a kind of student's desk, chair soft protective pad, mainly be on the desktop that plank is made and below the skin of blown polyurethane materials is all arranged, the desktop of polyurathamc is outer, and the both hands contact is soft, and winter is not ice-cold, do not ftracture, smooth again, be conducive to write, bump is light when placing study article, sound is low, keeps quiet surroundings.The above and below outer wall of the chair seat board that plank is made all has the skin of polyurathamc, takes softness, comfortable, and warming sense is arranged winter, and smooth surface, attractive in appearance is few to the trousers wearing and tearing.The chair back plate is generally plank and makes, but also the available metal plate is made, and is shaped with the skin of blown polyurethane materials at forward and backward all outer walls such as grade of chair back plate, and human body back leans against top comfortable, and smooth surface is light to wear of clothes, is collided flexible.The skin that polyurathamc is arranged again in the chair pin outside of the metals such as steel pipe, anti-collision, non-corrosive, elegant in appearance, the demeanour of raising chair pin increases fastness.At first make desktop, chair seat board, chair back plate and chair pin as prefabricated component when producing, then each prefabricated component is put into mould, inject polyurethane foams again in mould, it is outer to make the prefabrication surface form polyurathamc.The polyurathamc skin is nontoxic, to human body contact without harm, the polyurathamc long service life, smooth surface, intensity are good.After there has been unified painted polyurathamc skin on the surface of student's desk, chair, improve product specification, change the environment in classroom.
