Description

Folding health-protecting teaching writing board

The utility model is the folding health-protecting teaching writing board that belongs to teaching aid.

For a long time, teaching writing all is based on blackboard with plate, has the advantage of easy economy though write on blackboard with chalk during teaching, but the dust from flying that also exists chalk is to the certain influence of the healthy generation of teachers and students, simultaneously teacher stands in uprightly to write before the blackboard and also causes the back of the hand fatigue easily, and a large amount of consumption that chalk writes also can increase the education funds spending.In addition, people are in the today that heads towards the 21st century, and all trades and professions are all being advocated the protection environment energetically, and the traditional writing blackboard as teaching also should change its shortcoming, develops its advantage.The utility model design adopts the fat-like condensate oil plant to be applied to the new-type protecting teaching writing board of folding box-shaped plate inner face, just can make teachers ' teaching be seated or stand and writing without chalk, brings the flexibility that clipboard is folding and carry thereupon, and the obvious improvement of classroom environment.

The purpose of the utility model design, be to be to overcome traditional blackboard the shortcoming of writing with the chalk station, adopt the ultra-thin box-shaped plate of symmetrical fold, and be coated with the adhesive fat-like condensate oil plant that one deck and plate background color differ greatly at the inner face of folding box-shaped plate, be designed to folding health-protecting teaching writing board, make its both suitable teacher be seated or stand and directly on the fat-like condensate oil plant, write, alter or restore to the original state, can conveniently fold again and carry or be launched into a medium-sized protecting teaching writing board with wiping board is floating with the rod branch.

Also in conjunction with the accompanying drawings the utility model is described in detail as follows with embodiment below:

Fig. 1 is the structure chart of folding health-protecting teaching writing board;

Fig. 2 is the I-I cutaway view of folding health-protecting teaching writing board.

As shown in Figure 1, 2, the utility model is made up of folding box-shaped plate 1, hinge 2, fat-like condensate oil plant 3, hook 4 and handle 5, it is characterized in that being connected with three hinge 2 twistings by two symmetrical fold box-shaped plates 1, and just become the thin type casing to be fit to carry with handle 5 through folding, launch just to become a medium-sized protecting teaching writing board to be fit to hang on the wall with two hooks 4, adhesive fat-like condensate oil plant 3 is applied to the inner face of folding box-shaped plate 1, thereby forms the folding health-protecting teaching writing board of writing with excellent skill.Described folding box-shaped plate 1 be two with laminate, organic glass plate is bonding or the symmetrical fold box-shaped plate of the direct injection molded of plastics, the generally long 80cm of folded sheet, wide 70cm, hem width 1～2cm, thickness of slab 0.5cm, background color is based on white, and make inner face be fit to evenly smear the fat-like condensate oil plant 3 of adhesive, interior edge is connected with hinge 2 twistings, last edge flexibly connects with hook 4, and right edge and handle 5 flexibly connect.Fat-like condensate oil plant 3 is fit to be applied to equably the inner face of folding box-shaped plate 1, coating layer thickness is 1～2mm, be fit to write or floating with wiping board with rod, the preparation of its oil plant is to make carrier with good quality butter, the drier oil fat of adding 10% is in order to regulate oil plant humidity, adding 15% lard again changes with the soft or hard that summer and winter temperature occurs in order to regulate oil plant, make the fat-like condensate oil plant of band adhesive, gentle allowing property and fluent writing from face, the color of oil plant can be allocated with pigment as required, but requires to be the bigger the better with the aberration of base plate.

The folding health-protecting teaching writing board that designs and produces according to present embodiment, just can make two convenient folding carrying of folding box-shaped plate, be launched into a medium-sized protecting teaching writing board, teacher both can be seated or stand and using excellent skill to write, and also available wiping board is floating alters or restore to the original state.The utility model is novel in design and simple in structure, can eliminate the dust pollution that traditional blackboard is write with chalk, help guaranteeing teachers and students' health, and have flexible, the attractive in appearance and economical and practical advantage of font easy to use, so social benefit and the economic benefit of extensively promoting the use of arranged.
