Description

Telescopic pen

(1) technical field:

The utility model relates to telescopic pen, 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, the pen of ink storing tube is arranged, for example the fountain pen technical group field in the penholder.

(2) background technology:

At present, existing and once had about the pen of ink storing tube is arranged in the penholder, for example the technology of fountain pen group was all done very fruitful effort to the demand of telescopic pen, also once designed many outstanding technical schemes.As being declared by Yin Youli of the Decree of Patent Office of China in 1996, Granted publication is CN2229353Y, and China Patent No. (ZL) is: No. 95212675.3 utility model patent title is the utility model patent of " adjustable water-color paintbrush ", the technical scheme that is adopted.The pen that ink storing tube is arranged in penholder, for example the technical elements of fountain pen group is a routine of great value invention, but it has solved the technical problem of pen water transfer effectively.But still have some deficits, it also is difficult to solve the total bad technical problem that makes of spring of pen.

(3) summary of the invention:

The purpose of this utility model is to provide a kind of telescopic pen.With the total bad technical problem that makes of the spring that solves pen.

The telescopic pen 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: pen, ink barrel, spring, button, plug, the shaft of a writing brush, nib constitute.Its major part pen, ink barrel, spring are selected for use by market.Its pen is a post shapes, uses plastic material, moulds processing and manufacturing through watering.Its ink barrel is a post shapes, uses elastomeric material, through the casting processing and manufacturing.Its spring is spiral-shaped, uses the steel material, dials processing and manufacturing through shaking.Its button is a post shapes, uses plastic material, moulds processing and manufacturing through watering.Its plug is a post shapes, uses plastic material, moulds processing and manufacturing through watering, and its shaft of a writing brush is a post shapes, uses plastic material, moulds processing and manufacturing through watering.Its nib is a plate shape, uses the steel material, through the cold stamping processing and manufacturing.

In shape, textural, the total essential features of telescopic pen of the present utility model and immediate prior art is: the gluing lower end position that is connected pen of ink barrel, constitute post shapes rubber mass structure, and function has been to deposit the ink effect.Shaft of a writing brush screw thread is installed in the lower position of pen, constitutes post shapes polymer structure, and function has been to be convenient to hold a pen effect.Nib is inserted in the head position that is installed in pen, constitutes the plate shape steel structure, and function has been the effect of writing.In shape, textural, the telescopic pen of the present utility model technical characterictic different with immediate prior art is: spring is inlayed the upper end position that is installed in plug, constitutes spiral-shaped steel structure, and function has been to press the ink barrel effect.Button is inserted in the lowest positions that is installed in pen, constitutes post shapes polymer structure, and function has been the effect of manually pushing.Plug waters moulds the lower end position that is installed in button, constitutes post shapes polymer structure, and function has been the fixing spring effect.So just realized the purpose of the total bad technical problem that makes of spring of the solution pen of telescopic pen of the present utility model.

The beneficial effect of the telescopic pen of utility model be the utility model be solve pen the total bad technical scheme that technical problem adopted that makes of spring and existing and once had about the pen of ink storing tube is arranged in the penholder, for example the technology of fountain pen group has been compared three place's advantage and improvement:

The first, owing to designed spring in the technical scheme of telescopic pen of the present utility model, the technical problem of ink barrel is pressed in easier solution.

The second, owing to designed button in the technical scheme of telescopic pen of the present utility model, so the technical problem of easier solution hand push button.

The 3rd, owing to designed plug in the technical scheme of telescopic pen of the present utility model, so the technical problem of easier solution fixing spring.

(4) description of drawings:

Accompanying drawing provides the structural representation of telescopic pen of the present utility model:

Fig. 1: the overall structure schematic diagram that is telescopic pen of the present utility model:

The label declaration of parts in the schematic diagram:

1 pen, 2 ink barrels, 3 springs, 4 buttons, 5 plugs, 6 shafts of a writing brush, 7 nibs

(5) specific embodiment:

Below in conjunction with accompanying drawing, be that the optimal way that realization solves the technical scheme that the total bad technical problem that makes of spring of pen takes is described further to telescopic pen of the present utility model:

Its static structure: see also Fig. 1: as shown in the figure, telescopic pen of the present utility model mainly is made of pen 1, ink barrel 2, spring 3, button 4, plug 5, the shaft of a writing brush 6, nib 7.Its major part pen 1, ink barrel 2, spring 3 are selected for use by market.Its pen 1 is a post shapes, uses plastic material, moulds processing and manufacturing through watering.Its ink barrel 2 is post shapes, uses elastomeric material, through the casting processing and manufacturing.Its spring 3 is spiral-shaped, uses the steel material, dials processing and manufacturing through shaking.Its button 4 is post shapes, uses plastic material, moulds processing and manufacturing through watering.Its plug 5 is post shapes, uses plastic material, moulds processing and manufacturing through watering.Its shaft of a writing brush 6 is post shapes, uses plastic material, moulds processing and manufacturing through watering.Its nib 7 is plate shapes, uses the steel material, through the cold stamping processing and manufacturing.

In shape, textural, the total essential features of telescopic pen of the present utility model and immediate prior art is: the ink barrel 2 gluing lower end positions that are connected pen 1, constitute post shapes rubber mass structure, and function has been to deposit the ink effect.The shaft of a writing brush 6 screw threads are installed in the lower position of pen 1, constitute post shapes polymer structure, and function has been to be convenient to hold a pen effect.Nib 7 is inserted in the head position that is installed in pen 1, constitutes the plate shape steel structure, and function has been the effect of writing.In shape, textural, the telescopic pen of the present utility model technical characterictic different with immediate prior art is: spring 3 is inlayed the upper end position that is installed in plug 5, constitutes spiral-shaped steel structure, and function has been to press the ink barrel effect.Button 4 is inserted in the lowest positions that is installed in pen 1, constitutes post shapes polymer structure, and function has been the effect of manually pushing.Plug 5 waters moulds the lower end position that is installed in button 4, constitutes post shapes polymer structure, and function has been the fixing spring effect.

Its dynamic structure: in the optimal way of implementing, in use, in the time of suction, by push, button 4, according to the vacuum principle, its button 4 acts on ink by ink barrel 2, thereby finishes the task of suction.

Its dynamic structure: in the optimal way of implementing, in use, when water is bad instantly, by push, button 4 can extrude ink, according to extrusion principle, its button 4 acts on ink by ink barrel 2, thereby finishes the task of squeezing ink.So just realized the purpose of the total bad technical problem that makes of spring of the solution pen of telescopic pen of the present utility model.

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 a large number,, so just can realize the practical value and the economic worth of telescopic pen of the present utility model better with supply student's demand.
