Abstract

The utility model relates to a new chalks, belonging to the technical field of combined writing apparatus according to International Patent Classification, Operating and Transportation Section, Printing Subsection, Writing or Drawing Apparatus, Office Accessories, Subclass of writing or drawing apparatus, for multi-purpose such as multi-color writing apparatus. The utility model is composed of a chalk cover, a refill, a pencil vase and a nib. The purpose is that chalk of solid block has disadvantages of large waste, insufficiency of utilization, mass dust. The utility model is characterized in that: the refill is arranged inside the pencil vase, the screw thread of the nib is arranged in the front of the refill. The best way to fulfill the technical proposal is to take plastic as material, utilize the basic equipment of the stationery factory and adopt mass production to meet the needs of the education field and realize the practicality and economy value of the utility model.

Description

Novel chalk

(1) technical field:

The utility model relates to novel chalk, divides by International Patent Classification (IPC) (IPC) to belong to operation, Department of Transportation, printing branch, write or drawing appliance, the big class of office appliance is write or the drawing appliance group, many with for example polychrome writing implement, combination writing implement technical group field.

(2) background technology:

At present, existing and once had about many usefulness polychrome writing implement for example, the technology of combination writing implement group was all done very fruitful effort to the demand of novel chalk, also once designed many outstanding technical schemes.As declaring by height is loyal and righteous of the Decree of Patent Office of China, Granted publication is CN2188036Y, and China Patent No. (ZL) is: No. 94204965.9 utility model patent title is the utility model patent of " multi-functional combined pen ", the technical scheme that is adopted.With for example polychrome writing implement, the technical elements of combination writing implement group is a routine of great value invention many, and it has solved the multi-functional technical problem of pen effectively.But still have some deficits, it is big that its also be difficult to solve the waste of solid block chalk, utilizes insufficiently, plays the many technical problems of ash.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of novel chalk big to solve the waste of solid block chalk, utilizes insufficiently, plays the many technical problems of ash.

The chalk that the technical scheme that the technical problems to be solved in the utility model adopted is achieved in that this utility model mainly by: cap, pen core, pen container, nib constitute.Its cap is a cylindrical shape, uses plastic material, through moulding processing and manufacturing.Its pen core is a drum, uses plastic material, through moulding processing and manufacturing.Its pen container is a drum, uses plastic material, through moulding processing and manufacturing.Its nib is the spindle shape, with plastics outsourcing cotton layer material, through moulding processing and manufacturing.

In shape, textural, the total essential features of the utility model chalk and immediate prior art is: the cap screw thread is installed in the tail position of pen container, constitutes the cylindrical shape overall structure, and function is to seal.In shape, textural, the utility model chalk technical characterictic different with immediate prior art is: pen core embeds the inner position that is installed in pen container, constitutes the cylindrical shape overall structure, and function has been the effect of dress chalk powder.The nib screw thread is installed in the front position of pen core, constitutes the cylindrical shape overall structure, and function has been to derive the chalk powder effect of writing.The solid block chalk waste that has so just realized the utility model chalk is big, utilizes insufficiently, plays the many purposes of ash:

The beneficial effect of the chalk of utility model is that the utility model is to solve the waste of solid block chalk greatly, utilize insufficient, the technical schemes that technical problem adopted that play the many meanings of ash with existing and once had about many usefulness polychrome writing implement for example, make up the technology of writing implement group and compared a place's advantage and an improvement:

The first, owing to designed the pen core and the nib of the chalk powder of can packing in the technical scheme of the utility model chalk,, save raw material so be difficult for breaking, cleaner.

(4) description of drawings:

Accompanying drawing provides the structural representation of chalk of the present utility model:

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

The label declaration of parts in the schematic diagram: 1 cap, 2 pen cores, 3 pen containers, 4 nibs

(5) specific embodiment:

Below in conjunction with accompanying drawing, big to the utility model chalk for realize solving the waste of solid block chalk, utilize insufficiently, the optimal way that plays the technical scheme that the many technical problems of ash take is described further:

Its static structure: see also Fig. 1: as shown in the figure, the utility model chalk mainly is made of cap 1, pen core 2, pen container 3, nib 4.Its cap 1 is a cylindrical shape, uses plastic material, through moulding processing and manufacturing.Its pen core 2 is drums, uses plastic material, through moulding processing and manufacturing.Its pen container 3 is drums, uses plastic material, through moulding processing and manufacturing.Its nib 4 is spindle shapes, with plastics outsourcing cotton layer material, through moulding processing and manufacturing.

In shape, textural, the total essential features of the utility model chalk and immediate prior art is: cap 1 screw thread is installed in the tail position of pen container 3, constitutes the cylindrical shape overall structure, and function is to seal.In shape, textural, the utility model chalk technical characterictic different with immediate prior art is: pen core 2 embeds the inner position that is installed in pen container 3, constitutes the cylindrical shape overall structure, and function has been the effect of dress chalk powder.Nib 4 screw threads are installed in the front position of pen core 2, constitute the cylindrical shape overall structure, and function has been to derive the chalk powder effect of writing.

Its dynamic structure: in the optimal way of implementing, in use, when will write the blackboard word, chalk powder is injected pen core 2, and when writing, chalk powder flows out from nib 4, according to mechanics principle, its pen container 3 acts on nib 4 by pen core 2, thereby finishes the task of writing.The solid block chalk waste that has so just realized the utility model chalk is big, utilizes insufficiently, plays the many purposes of ash.

Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of stationery factory, take to produce by batch in batches,, so just can realize the practical value and the economic worth of the utility model chalk better with the demand of supply educational circles.

Claims
