Description

The multifunctional chalk cover

(1) technical field:

The utility model relates to the multifunctional chalk cover, divides by International Patent Classification (IPC) (IPC) to belong to operation Department of Transportation, and printing branch is write or drawing appliance; The big class of office appliance is write or the drawing appliance group clamper of writing implement or connector; Big group of the protector of reservoir tip, wax crayon or the little technical group field of chalk clamper.

(2) background technology:

At present, clamper or the connector that has now and once had about writing implement; Big group of the protector of reservoir tip, the technology of wax crayon or chalk clamper group was all done very fruitful effort to the needs of multifunctional chalk cover, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 2008 by sincere rosy clouds, Granted publication number is CN201257834Y, China Patent No. (ZL) is: No. 200820115487.8 utility model title is the utility model patent of " simple and easy chalk sleeve ", the technical scheme that is adopted is at the clamper or the connector of writing implement; Big group of the protector of reservoir tip, wax crayon or chalk clamper group technical elements are routine of great value inventions, this has solved the technical problem of simple and easy chalk sleeve effectively.But still have some deficits, it also is difficult to separate never hinders hand; Anti-skidding technical problem.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of multifunctional chalk cover.Never hinder hand to separate; Anti-skidding technical problem.

The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: utility model multifunctional chalk cover mainly is made of button, spring, the cap for brush, clamp, penholder, non-skid film, chalk.Its major part button, spring, non-skid film are selected for use by market.Its cap for brush is a circular shape, is material with plastics, through the machined manufacturing.Its clamp is a cylindrical shape, is material with plastics, through the machined manufacturing.Its penholder is a drum, is material with plastics, through the machined manufacturing.

In shape, structure and combination thereof, multifunctional chalk cover of the present utility model with the essential features that immediate prior art has is: the integral body of chalk is by the powder metallurgy sintered one that is processed into, and function has been the effect of chalk.In shape, structure and combination thereof, the multifunctional chalk cover of the present utility model technical characterictic different with immediate prior art is: the integral body of chalk is inserted into the inside of penholder, the upper end of chalk is inserted into the lower end of clamp, the upper end of clamp is connected the lower end of button by spring, the overall fixed of clamp and spring is installed in the inside of the cap for brush, button is installed in the upper end of the cap for brush, the cap for brush is fixedly connected on the upper surface of penholder by screw thread, be combined into the combining structure of pen shape, function has been the effect of not hindering hand.The integral body of non-skid film is enclosed within the outer surface of penholder, is combined into the integrative-structure of cylindrical shape, and function has been anti-skidding effect.What so just reached multifunctional chalk of the present utility model cover does not hinder hand; Anti-skidding purpose.

The beneficial effect of the multifunctional chalk cover of utility model is that the utility model is never hindered hand for separating; The anti-skidding technical scheme that technical problem adopted and clamper or connector about writing implement existing and that once had; Big group of the protector of reservoir tip, the technology of wax crayon or chalk clamper group has been compared two place's advantage and improvement:

First, because the integral body that has designed chalk in the technical scheme of multifunctional chalk cover of the present utility model is inserted into the inside of penholder, the upper end of chalk is inserted into the lower end of clamp, the upper end of clamp is connected the lower end of button by spring, the overall fixed of clamp and spring is installed in the inside of the cap for brush, button is installed in the upper end of the cap for brush, and the cap for brush is fixedly connected on the upper surface of penholder by screw thread, so the easier technical problem of never hindering hand of separating.

The second, owing to designed the outer surface that the integral body of non-skid film is enclosed within penholder in the technical scheme of multifunctional chalk of the present utility model cover, so the anti-skidding technical problem of easier solution.

(4) description of drawings:

Accompanying drawing provides the structural representation of the utility model multifunctional chalk cover:

Fig. 1: the overall structure schematic diagram that is the utility model multifunctional chalk cover.

The label declaration at each position in the schematic diagram;

1 button, 2 springs, 3 caps for brush, 4 clamps

5 penholders, 6 non-skid films, 7 chalks

(5) specific embodiment:

Below in conjunction with accompanying drawing, multifunctional chalk cover of the present utility model is never hindered hand for realizing separating; The optimal way of the technical scheme that anti-skidding technical problem is taked is described further:

Its static structure: see also accompanying drawing: as shown in the figure, multifunctional chalk cover of the present utility model mainly is made of button 1, spring 2, the cap for brush 3, clamp 4, penholder 5, non-skid film 6, chalk 7.Its major part button 1, spring 2, non-skid film 6 are selected for use by market.Its cap for brush 3 is circular shapes, is material with plastics, through the machined manufacturing.Its clamp 4 is cylindrical shapes, is material with plastics, through the machined manufacturing.Its penholder 5 is drums, is material with plastics, through the machined manufacturing.

In shape, structure and combination thereof, multifunctional chalk cover of the present utility model with the essential features that immediate prior art has is: the integral body of chalk 7 is by the powder metallurgy sintered one that is processed into, and function has been the effect of chalk.In shape, structure and combination thereof, the multifunctional chalk cover of the present utility model technical characterictic different with immediate prior art is: the integral body of chalk 7 is inserted into the inside of penholder 5, the upper end of chalk 7 is inserted into the lower end of clamp 4, the upper end of clamp 4 is connected the lower end of button 1 by spring 2, the overall fixed of clamp 4 and spring 2 is installed in the inside of the cap for brush 3, button 1 is installed in the upper end of the cap for brush 3, the cap for brush 3 is fixedly connected on the upper surface of penholder 5 by screw thread, be combined into the combining structure of pen shape, function has been the effect of not hindering hand.The integral body of non-skid film 6 is enclosed within the outer surface of penholder 5, is combined into the integrative-structure of cylindrical shape, and function has been anti-skidding effect.

Below by using method, further set forth the dynamic structure relation of the utility model multifunctional chalk cover: in use, when needs are not hindered hand, according to theory of mechanics, at first the integral body of chalk 7 is inserted into the inside of penholder 5, the upper end of chalk 7 is inserted into the lower end of clamp 4, the upper end of clamp 4 is connected the lower end of button 1 by spring 2, the overall fixed of clamp 4 and spring 2 is installed in the inside of the cap for brush 3, button 1 is installed in the upper end of the cap for brush 3, the cap for brush 3 is fixedly connected on the upper surface of penholder 5 by screw thread, thereby finishes the task of not hindering hand.

In use, when needs were anti-skidding, according to theory of mechanics, at first the integral body of non-skid film 6 was enclosed within the outer surface of penholder 5, thereby finished anti-skidding task.That has so just realized the utility model multifunctional chalk cover does not hinder hand; Anti-skidding technical problem.

Realize that the utility model preferred plan is with plastic material, utilize the basic equipment of chalk sleeve processing factory, take to produce by batch in a large number,, so just can realize the practical value and the economic worth of the utility model multifunctional chalk cover better with the demand of supply educational circles.
