The code mark of the utility model is B43L1/04, and the utility model is composed of a connection chain, a pulley wheel, a fixed slice, a blackboard box, a guide rail, a blackboard, a blackboard frame, a board eraser frame and screw nails. The utility model is characterized in that the long chain-shaped connection chain is installed on the rectangular blackboard, and the utility model is a novel blackboard with practical value.

Description

A kind of new type blackboard

The utility model relates to a kind of new type blackboard.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, the big class of office appliance, write or the drawing article assistant product group of writing or draw big group of reusable plate of writing or drawing or tablet, the little technical group field of blackboard.Be numbered B43L1/04.

At present, existing and once had about big group of the reusable plate of writing or drawing or tablet, the demand that the technology of blackboard group is right was all done very fruitful effort, also once designed many outstanding technical schemes.As being declared by Li Zuohuai of the Decree of Patent Office of China in 1996, Granted publication number is CN2236953Y, and China Patent No. (ZL) is: 95242106.No. 2 utility model title is the utility model patent of " combined type gravity disappear the dustless board of word ", the technical scheme that is adopted.Big group of the reusable plate of writing or drawing or tablet, blackboard group technical elements is a routine of great value invention, and it has solved the disappear problem of word of board combined type gravity effectively.But still have some deficits, blackboard was higher before it also was difficult to solve, and teacher can not write the lower problem of utilization rate topmost.

The purpose of this utility model is to provide a kind of new type blackboard.Higher with blackboard before solving, teacher can not write the lower problem of utilization rate topmost.

The purpose of this utility model is achieved in that a kind of new type blackboard of this utility model.Mainly constitute by connection chain, pulley, stator, blackboard box, guide rail, blackboard, blackboard frame, blackboard eraser frame, screw.Its major part pulley is by selecting for use on the market.Its blackboard is the rectangular sheet shape, makes material with glass, through the cutting processing manufacturing.Its blackboard frame is an elongate in shape, makes material with timber, through the planing operation manufacturing.Its guide rail is an elongate in shape, makes material with metal, through the planing operation manufacturing.The blackboard of its lamella shape adopts method for embedding to be installed on the blackboard frame of rectangular-shaped frame shape, forms the structure of writing of a square matrix shape.The connection chain of its long-chain shape adopts screw-jointing method to be installed on the blackboard of rectangular shape.Form the syndeton of a chain shape.The pulley of its disc-shape adopts screw-jointing method to be installed on the blackboard box of rectangular box shape.Form the slide construction that holds of a square type shape.The guide rail of its elongate in shape adopts screw-jointing method to be installed on the blackboard box of rectangular shape.Form the guide frame of an elongate in shape.Its blackboard box acts on pulley by connection chain, thereby makes the blackboard box satisfy the requirement that slides up and down.Its blackboard eraser frame acts on the blackboard box by screw, thereby makes the blackboard eraser frame finish the task of connecing chalk dust and blackboard eraser.So just realized the purpose of this utility model.

Big group of the utility model and the original reusable plate of writing or drawing or tablet, the technology of blackboard group has been compared three advantages and improvement;

The first, because the utility model has designed blackboard in technical scheme, so solved the problem that can write letter written with chalk;

The second, because the utility model has designed two blackboards in technical scheme, so solved the problem that has increased write area;

The 3rd, because the utility model has designed pulley in technical scheme, so solved very convenient two problems that blackboard moves up and down.Thereby it is higher just more effectively to have solved former blackboard, and teacher can not write the lower problem of utilization rate topmost.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the agent structure schematic diagram of a kind of new type blackboard of the utility model;

Fig. 2 is the side rail structure schematic diagram of a kind of new type blackboard of the utility model;

The numbering of parts explanation in the schematic diagram: 1 connection chain, 2 pulleys, 3 stators, 4 blackboard boxes, 5 guide rails, 6 blackboards, 7 blackboard frames, 8 blackboard eraser framves, 9 screws

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in the figure, a kind of new type blackboard of the utility model.Mainly constitute by connection chain 1, pulley 2, stator 3, blackboard box 4, guide rail 5, blackboard 6, blackboard frame 7, blackboard eraser frame 8, screw 9.Its major part pulley 2 is by selecting for use on the market.Its blackboard 6 is rectangular sheet shapes, makes material with glass, through the cutting processing manufacturing.Its blackboard frame 7 is elongate in shape, makes material with timber, through the planing operation manufacturing.Its guide rail 5 is elongate in shape, makes material with metal, through the planing operation manufacturing.The blackboard 6 of its lamella shape adopts method for embedding to be installed on the blackboard frame 7 of rectangular-shaped frame shape, forms the structure of writing of a square matrix shape.The connection chain 1 of its long-chain shape adopts screw-jointing method to be installed on the blackboard 6 of rectangular shape.Form the syndeton of a chain shape.The pulley 2 of its disc-shape adopts screw-jointing method to be installed on the blackboard box 4 of rectangular box shape.Form the slide construction that holds of a square type shape.The guide rail 5 of its elongate in shape adopts screw-jointing method to be installed on the blackboard box 4 of rectangular shape.Form the guide frame of an elongate in shape.Its blackboard box 4 acts on pulley 2 by connection chain 1, thereby makes blackboard box 4 satisfy the requirement that slides up and down.Its blackboard eraser frame 8 acts on blackboard box 4 by screw, thereby makes blackboard eraser frame 8 finish the task of connecing chalk dust and blackboard eraser.So just realized the purpose of this utility model.Thereby it is higher just to have solved former blackboard, and teacher can not write the lower problem of utilization rate topmost.

Below by embodiment, the utility model is done more detailed description:

Embodiment 1, in force, if in real life, because blackboard in the past is very high, the teacher is difficult to full blackboard is write in writing on the blackboard, so that teacher is not high to the utilization rate of blackboard, just always write and wiped, it is very difficult that the classmate is taken notes, and the utility model is easy to address this problem owing to designed two blackboards that slide up and down.

Embodiment 2, and in force, in life, if De Taigao write in word, not easy-to-use blackboard eraser is wiped, and it is very difficult to make that the classmate erases the board after class, and the utility model is then owing to designed two Sliding blackboards up and down.Thereby just can realize the purpose of this utility model.

Realize that preferred plan of the present utility model is is material with glass, timber, utilize the basic equipment of school supply and stationery factory, take Mechanized Processing to produce by batch, the demand with supply cultural and educational circles so just can realize practical value of the present utility model and economic worth better.
