Description

A kind of novel chalk protector
The utility model relates to a kind of novel chalk protector.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance, and the big class of office appliance is write or the drawing appliance group clamper of pencil or chalk; The pencil connector; The protector technical group field of reservoir tip.Classification number is B43K23/00.
At present, the clamper that has now and once had about pencil or chalk; The pencil connector; The technology of the protector of reservoir tip was all done very fruitful effort to the demand of novel chalk protector, also once designed many outstanding technical schemes.As being declared by Chen Juxin of the Decree of Patent Office of China in 1996, Granted publication number is CN2206726Y, and China Patent No. (ZL) is: No. 94246848.1 utility model title is the utility model patent of " a kind of chalk sleeve ", the technical scheme that is adopted.Clamper at pencil or chalk; The pencil connector; The protector technical elements of reservoir tip is a routine of great value invention, and it has solved the problem of chalk sleeve effectively.But still have some deficits, it also is difficult to solve the easily broken uncleanly problem of chalk.
The purpose of this utility model is to provide a kind of novel chalk protector.To solve the easily broken uncleanly problem of chalk.
The purpose of this utility model is achieved in that a kind of novel chalk protector of this utility model.Mainly constitute by the cap for brush, chalk, lid, shell, internal layer cover, movable sleeve, rear.Its chalk is by selecting for use on the market.Its cap for brush, shell, internal layer cover, movable sleeve, rear are cylindrical shapes, use plastic material, through the thermoforming processing and manufacturing.Its lid is a cone shape, uses plastic material, through the thermoforming processing and manufacturing.Lid adopts screw method to be installed in the position of upper of shell, constitutes the cone shape superstructure, and function is to play the role of positioning.Chalk adopts the insertion method to be installed in the center of movable sleeve, constitutes a cylindrical shape structure, and function has been the effect of writing.Movable sleeve adopts screw method to be installed in the center of internal layer cover, constitutes the cylindrical shape sleeve structure, and function is to play a driving role.The internal layer cover adopts embedding grammar to be installed in the center of shell, constitutes multilayer shape sleeve structure, and function is to play rotating action.Rear adopts adhering method to be installed in the tail position of internal layer cover, constitutes the cylindrical shape tail structure, and function is to play rotating action.So just realized the purpose of this utility model.
The advantage of utility model: the utility model and original pencil or the clamper of chalk; The pencil connector; The protector technology of reservoir tip has been compared two advantages and improvement;
The first, because the utility model has designed shell in technical scheme, so the hand of can not making dirty;
The second, because the utility model has designed movable sleeve in technical scheme, institute is so that chalk is not easily broken; Thereby just can more effectively solve the easily broken uncleanly problem of chalk.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the agent structure schematic diagram of a kind of novel chalk protector of the utility model;
The numbering of parts explanation in the schematic diagram: 1 cap for brush, 2 chalks, 3 lids, 4 shells, 5 internal layers overlap 6 movable sleeves, 7 rears
In the optimum implementation of a kind of novel chalk protector 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 novel chalk protector of the utility model.Mainly constitute by the cap for brush 1, chalk 2, lid 3, shell 4, internal layer cover 5, movable sleeve 6, rear 7.Lid 3 adopts screw method to be installed in the position of upper of shell 4, constitutes the cone shape superstructure, and function is to play the role of positioning.Chalk 2 adopts the insertion method to be installed in the center of movable sleeve 6, constitutes a cylindrical shape structure, and function has been the effect of writing.Movable sleeve 6 adopts screw method to be installed in the center of internal layer cover 5, constitutes the cylindrical shape sleeve structure, and function is to play a driving role.Internal layer cover 5 adopts embedding grammar to be installed in the center of shell 4, constitutes multilayer shape sleeve structure, and function is to play rotating action.Rear 7 adopts adhering method to be installed in the tail position of internal layer cover 5, constitutes the cylindrical shape tail structure, and function is to play rotating action.
Its dynamic structure: in force:
Its internal layer cover 5 acts on chalk 2 by movable sleeve 6, thereby finishes the task of writing.So just realized the purpose of this utility model.Thereby just can solve the easily broken uncleanly problem of chalk.
Below by using method, the utility model is done more detailed description:
A kind of novel chalk protector of this utility model is work like this:
In use, when need are write, at first the cap for brush 1 is taken, rotation rear 7, drive the internal layer cover 5 in the shell 4, the rotation of internal layer cover 5 is passed to movable sleeve 6 by threaded engagement, and movable sleeve 6 moves upward, promoting chalk 2 stretches out from covering 3, for writing, write finish after, reverse rotation rear 7, make chalk 2 withdrawals, cover the tight cap for brush 1 and get final product.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of stationery factory, take thermoforming to produce in batch, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
