The class number of the utility model is B43L1/00. The utility model is composed of a brush board, a blackboard body, a suspension loop, a shaft of a rotating wheel, a rotating wheel, a hole-shaped band and a rocking rod. The utility model is characterized in that the brush board is arranged in the middle of the hole-shaped band. The novel blackboard of the utility model has high practical value.
Description
The utility model relates to a kind of new type blackboard.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write the big class of worker or drawing article, write or drawing article, the 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.Classification number is B43L1/00.
At present, the technology about blackboard existing and that once had was all done very fruitful effort to the demand of new type blackboard, also once designed many outstanding technical schemes.As being declared by Jia Yusheng of the Decree of Patent Office of China in 1996, Granted publication number is CN2222619Y, and China Patent No. (ZL) is: No. 95212828.4 utility model title is the utility model patent of " portable blackboard ", the technical scheme that is adopted.Be a routine of great value invention aspect blackboard, it has solved the portable problem of blackboard effectively.But still have some deficits, it also is difficult to the problem that solution can be removed chalk writing fast.
The purpose of this utility model is to provide a kind of new type blackboard.To solve the problem that to remove chalk writing fast.
The purpose of this utility model is achieved in that a kind of new type blackboard of this utility model.Mainly constitute by brush board, blackboard body, link, runner shaft, runner, hole shape band, rocking bar.Its blackboard body is the twisted plate shape, uses plastic material, through the injection mo(u)lding processing and manufacturing.Its runner is a band tooth disc-shape, uses the steel material, through the casting processing and manufacturing.Its runner shaft is a cylindrical shape, uses the steel material, through the roll-in processing and manufacturing.Its rocking bar is the bent axle shape, uses the steel material, through the thermoforming processing and manufacturing.Its brush board is a tape shape shape, uses the thermoforming processing and manufacturing.Runner shaft adopts the bearing coupling method to be installed in the upper and lower end position of blackboard body, constitutes thin cylindrical shape pivot structure, and function has been fixedly runner effect.Runner adopts the interference fit method to be installed in the end positions of runner shaft, constitutes the disc-like shape wheel structure, and function has been that the effect of hole shape band is installed.The hole shape band adopts the direct method of being inserted in to be installed in the peripheral position of runner, looping shape drive mechanism, and function has been that the drive brush board moves up and down effect.Rocking bar adopts welding method to be connected the right end position of lower whorl rotating shaft, constitutes bent axle shape force application structure, and function has been to drive the rotating shaft rotary action.Brush board adopts the screw fixing means to be installed in the centre position of hole shape band, constitutes the batten shape, and function has been the effect of erasing the board.Link adopts the screw fixing means to be installed in two side positions of blackboard body, and function has been to hang the blackboard body effect.So just realized the purpose of this utility model.
The utility model has been compared three advantages and improvement with original blackboard;
The first, because the utility model has designed the belt strip brush plate in technical scheme, so can remove chalk writing simultaneously in large area;
The second, because the utility model has designed runner and hole shape band in technical scheme, brush board is upper and lower to be moved so can drive;
The 3rd, because the utility model has designed rocking bar in technical scheme, so make things convenient for the rotation of runner; Thereby just can more effectively solve the problem that to remove chalk writing fast.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the general structure schematic diagram of a kind of new type blackboard of the utility model;
Fig. 2 is the side-looking structural representation of a kind of new type blackboard of the utility model;
The numbering of parts explanation in the schematic diagram: 1 brush board, 2 blackboard bodies, 3 links, 4 runner shafts, 5 runners, 6 hole shape bands, 7 rocking bars
In the optimum implementation of a kind of new type blackboard of the utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:
Its static structure: as shown in the figure, a kind of new type blackboard of the utility model.Mainly constitute by brush board 1, blackboard body 2, link 3, runner shaft 4, runner 5, hole shape band 6, rocking bar 7.Runner shaft 4 adopts the bearing coupling method to be installed in the upper and lower end position of blackboard body 2, constitutes thin cylindrical shape pivot structure, and function has been fixedly runner effect.Runner 5 adopts the interference fit method to be installed in the end positions of runner shaft 4, constitutes the disc-like shape wheel structure, and function has been that the effect of hole shape band is installed.Hole shape band 6 adopts the direct method of being inserted in to be installed in the peripheral position of runner 5, looping shape drive mechanism, and function has been that the drive brush board moves up and down effect.Rocking bar 7 adopts welding method to be connected the right end position of lower whorl rotating shaft, constitutes bent axle shape force application structure, and function has been to drive the rotating shaft rotary action.Brush board 1 adopts the screw fixing means to be installed in the centre position of hole shape band 6, constitutes the batten shape, and function has been the effect of erasing the board.Link 3 adopts the screw fixing means to be installed in two side positions of blackboard body 2, and function has been to hang the blackboard body effect.
Its dynamic structure: in force:
According to the rocking bar principle, its rocking bar 7 acts on runner 5, thereby finishes the task that runner rotates that drives.According to the chain drive principle, its runner 5 passes through the tooth gearing in hole shape band 6, thereby finishes the task of driving the motion of hole shape band.So just realized the purpose of this utility model.Thereby just can solve the problem that to remove chalk writing fast.
Below by using method, the utility model is done more detailed description:
A kind of new type blackboard of this utility model is work like this:
In use, when writing writing on the blackboard, shake rocking bar 7, the rotating shaft of lower end and runner just rotate, just driving hole shape band 6 by the tooth transmission between runner 5 and the hole shape band 6 like this moves down, and hole shape band 6 drives brush board 1 and moves down, and till blackboard body 2 least significant ends, just can write writing on the blackboard this moment until brush board 1.
In use, when will erase the board, counter-rotation rocking bar 7 by runner 5 and hole shape band 6, drives brush board 1 and moves up.At this moment, the bristle on the brush board 1 slips on blackboard surface, and the chalk writing on the blackboard has just been wiped.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of teaching aid factory, take single-piece production, unite to assemble and produce by batch, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
