Abstract
The utility model relates to a novel four line lattice drawing chalk. According to the International Patent Classification(IPC), the utility model pertains to the technical field of the group of non-propelling pencils, styles, crayons and chalks, the subclass of implements for writing or drawing, the class of writing or drawing implements and bureau accessories, the subsection of printing, the section of performing operations and transporting. The classification number of the utility model is B43K19/00. The utility model comprises a sleeve, a socket mat plate, a chalk and a pushing screw. The utility model is characterized in that the column-shaped sleeve is arranged on the oblong socket mat plate. The utility model is a novel four line lattice drawing chalk with a great practical value.
Description
The utility model relates to novel picture four line lattice chalks.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, and the big class of office appliance is write or the drawing appliance group, non-propelling pencil, stylus, chalk technical group field.Be numbered B43K19/00.
At present, the technology about non-propelling pencil, stylus, chalk existing and that once had was all done very fruitful effort to the demand of novel picture four line lattice chalks, also once designed many outstanding technical schemes.As being declared by Zhou Wei of the Decree of Patent Office of China in 1996, Granted publication number is CN2235898Y, and China Patent No. (ZL) is: No. 95206789.7 utility model title is the utility model patent of " Pen for writing on card ", the technical scheme that is adopted.At non-propelling pencil, stylus, chalk technical elements is a routine of great value invention, and it has solved the problem of Pen for writing on card effectively.But still have some deficits, it also is difficult to solve the problem of drawing four lines on blackboard as early as possible.
The purpose of this utility model is to provide a kind of novel picture four line lattice chalks.To solve the problem of on blackboard, drawing four lines as early as possible.
The purpose of this utility model is achieved in that the novel picture four line lattice chalks of this utility model.Mainly constitute by sleeve, groove backing plate, chalk, boosting screw.Its major part sleeve is a cylindrical shape, makes material with steel, through the machining manufacturing.Its groove backing plate is a rectangular shape, makes material with steel, through the machining manufacturing.Its boosting screw is a cylindrical shape, makes material with steel, through the machining manufacturing.The chalk of its cylindrical shape adopts the interference fit method to be installed on the sleeve of cylindrical shape.Form the chalk structure of a cylindrical shape.The sleeve of its cylindrical shape adopts method of attaching to be installed on the groove backing plate of rectangular shape.Form the tube-in-tube structure of a cylindrical shape.The boosting screw of its cylindrical shape adopts the secondary fitting method of screw to be installed on the sleeve of cylindrical shape.Form the boosting screw structural of a cylindrical shape.The chalk bottom of its cylindrical shape adopts contact method to be installed on the boosting screw of cylinder form.Form the pushed away chalk structure of a cylindrical shape.Its sleeve acts on chalk by tight fit.Thereby make chalk satisfy fixing requirement.Its boosting screw is by contacting impetus in chalk.Thereby make chalk finish the task of alignment.So just realized the purpose of this utility model.
The utility model has been compared three advantages and improvement with original non-propelling pencil, stylus, chalk technology;
The first, because the utility model has designed sleeve in technical scheme, so solved the easy problem of chalk of installing;
The second, because the utility model has designed the boosting screw in technical scheme, so solved the problem that promotes chalk;
The 3rd, because the utility model has designed the groove type backing plate in technical scheme, so solved the problem of being convenient to install the boosting screw.Thereby just can more effectively solve the problem of on blackboard, drawing four lines as early as possible.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the overall structure schematic diagram of novel picture four line lattice chalks of the present utility model;
Fig. 2 is the single assist device structural representation of novel picture four line lattice chalks of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 sleeve, 2 groove backing plates, 3 chalks, 4 boosting screws
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, novel picture four line lattice chalks of the present utility model.Mainly constitute by sleeve 1, groove backing plate 2, chalk 3, boosting screw 4.Its major part sleeve 1 is a cylindrical shape, makes material with steel, through the machining manufacturing.Its groove backing plate 2 is rectangular shapes, makes material with steel, through the machining manufacturing.Its boosting screw 4 is cylindrical shapes, makes material with steel, through the machining manufacturing.The chalk 3 of its cylindrical shape adopts the interference fit method to be installed on the sleeve 1 of cylindrical shape.Form the chalk structure of a cylindrical shape.The sleeve 1 of its cylindrical shape adopts method of attaching to be installed on the groove backing plate 2 of rectangular shape.Form the tube-in-tube structure of a cylindrical shape.The boosting screw 4 of its cylindrical shape adopts the secondary fitting method of screw to be installed on the sleeve 1 of cylindrical shape.Form the boosting screw structural of a cylindrical shape.The chalk bottom of its cylindrical shape adopts contact method to be installed on the boosting screw 4 of cylinder form.Form the pushed away chalk structure of a cylindrical shape.Its sleeve 1 acts on chalk 3 by tight fit.Thereby make chalk 3 satisfy fixing requirement.Its boosting screw 4 is by contacting impetus in chalk 3.Thereby make chalk 3 finish the task of alignment.So just realized the purpose of this utility model.Thereby just can solve the problem of on blackboard, drawing four lines as early as possible.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, and in force, if think to draw simultaneously four parallel lines, available this design is held backing plate and drawn on blackboard.
Realize that preferred plan of the present utility model is is material with the steel, utilize the basic equipment of machining factory, take machining to produce in batch, the demand with supply school circle so just can realize practical value of the present utility model and economic worth better.
