Abstract
The utility model relates to a multifunctional needle tube drawing pen for drawing blueprints for various projects and scientific researches and writing. The liquid limiting valve of the utility model prevents ink leaking from a pen nib and dual diversion needles can conveniently eliminate the failure of needle bodies from bending. The liquid limiting valve and the diversion needles, which are controlled by springs, make the drawing pen be normally used at various angles with the level surface and a suite of adapter devices with different shapes can connect the drawing pen with different models of graphics plotters as well as being hand-operated.
Description
Multi-functional needle tubing drawing pen relates to a kind of drawing and lettering pen with needle tube type nib, is used for engineering, the drafting of scientific research drawing and character calligraph.
The needle tubing drawing pen of existing use is by penholder, accumulator, and connector, adapter, pen core, needle tubing, the needle tubing seat, cylindricality weight behind water conservancy diversion pin and the water conservancy diversion pin is formed, as United States Patent (USP) 3539269,3836266 and No. 4522525 etc.These drawing pens are by the outflow of the capillarity in slit control ink between the water conservancy diversion pin in needle tubing and the needle tubing.The water conservancy diversion pin is driven by weight thereafter, moves under the gravity effect, plays and dredges ink, the effect of cleaning and unobstructed needle tubing.The adapter of penholder front end has single shape, is applicable to manual drawing, or only is used for certain instrumental drawing.Above-mentioned various needle tubing pen exists following problem:
1. in some cases, such as holding the penholder overlong time, a temperature raises in the pen, causes air pressure to raise ink when nib extrudes, or since drawing pen vibrate vertically ink when nib is discharged.The capillarity of existing drawing pen nib can not stop ink to flow out from nib, thereby causes the pollution of drawing.
2. when the water conservancy diversion pin is crooked, must change needle body and subsequent weight.Because the water conservancy diversion pin is very tiny, it carries and stores very difficulty.In some cases, because the accessory deficiency can not in time be changed, the bending of water conservancy diversion pin may cause drawing pen to be scrapped.
3. these drawing pens require handwriting basic vertical with horizontal plane in use usually, to guarantee that the water conservancy diversion pin is by thereafter weight drive operate as normal under the gravity effect.When the perpendicularity of drawing pen is not enough (when particularly some plotter requires the drawing pen level installed), gravity deficiency makes the water conservancy diversion pin of drawing pen be difficult to move, thereby causes the water outlet of nib smooth or by the obstruction of the fiber on paper needle tubing.
4. end adapter only has a kind of shape before the penholder of these drawing pens, is used for manual operations, and individual other also can only be exclusively used in a certain plotter and draw, and costs an arm and a leg.And the needle tubing drawing pen that a large amount of complotters does not adapt with it.And the drawing pen of similar shape plotter can not exchange use, and manual drawing pen can not be used for instrumental drawing.Cause a large amount of drawings can only manual drawing, operating efficiency be very low.
The purpose of this utility model is to overcome above-mentioned 4 deficiencies of the drawing pen of above-mentioned existing use.A kind of manual drawing that promptly can be used for is provided, also can be used for instrumental drawing, needle tubing drawing pen easy to use, cheap.
The utility model changes the cylindricality weight by spring driven flow-limiting valve on the basis of existing technology, makes that when needle tubing did not touch writing surface, ink can not flow out from nib.The water conservancy diversion pin at flow-limiting valve two ends can be when a needle body bending, another is replaced simply come, thereby ensure the operate as normal of drawing pen.Multi-functional needle tubing drawing pen has a cover and can be installed in the adapter on a connector, can select to use when different purposes (manual draw or be used with different plotters), in the hope of usefulness more than one.
Fig. 1 is the axial section schematic diagram of an embodiment of the utility model.Fig. 2 and Fig. 3 are the schematic diagrames of flow-limiting valve shape among two other embodiment.Fig. 4 and Fig. 5 be embodiment as shown in Figure 1 two different adapters dwindle generalized section.
Below in conjunction with embodiment the utility model is described.
As shown in Figure 1, needle tubing 1 is plugged on the base 3; Base 3 is screwed on the pen core 6 by spiral shell button 9; Two ends have identical water conservancy diversion pin 2 and 2 ' flow-limiting valve 4(sphere) match with valve seat 4 ' (hemispherical) on the needle tubing seat 3; The two end supports of spring 5 is on the annular projection 7 on the interior pipe 19 of flow-limiting valve 4 and pen core 6; Pen core 6 is plugged on the connector 10; Adapter 11 is screwed on the connector 10 by spiral shell button 17; Three annular projections 12,13 are arranged on the adapter 11; Penholder 14 is buckled 18 by spiral shell and is screwed on the connector 10; Accumulator 16 is plugged on the projection 15 of connector 10.
When drawing pen is worked, water conservancy diversion needle point 2 " write in the thing surface pressure back stitching pipe 1, thereby with flow-limiting valve 4 from valve seat 4 ' go up jack-up, open this valve, ink is evenly flowed out along needle tubing 1.When drawing pen quits work from writing the thing surface when leaving, spring 5 with flow-limiting valve 4 push back valve seat 4 ', cut off the supply of ink to needle tubing 1, raise or handwriting when vibrating vertically in the handwriting internal pressure, avoided the leakage of ink, prevented the accident that drawing pollutes from needle tubing 1.When water conservancy diversion pin 2 bends, needle tubing seat 3 can be screwed off from pen core 6, with water conservancy diversion pin 2 ' be transposed to 2 position, fix a breakdown rapidly simply.Three annular protrusions 12,13rd on the adapter 11 among the embodiment, for the pen-holding device that cooperates a kind of complotter designs, present embodiment also is furnished with other different adapter, adapter 11 as shown in Figure 4 and Figure 5 ' and 11 ".These adapters all are the cylinders of a hollow.Concrete shape may be the garden post of hollow, six prisms or triangular prism.There are some projectioies or groove in the cylinder outside, to be fit to the pen-holding device of different plotters.Their internal structures are all identical, can be screwed on the connector 10 among Fig. 1 by spiral shell button 17.Adapter a 11 ' annular projection 20 is arranged is a kind of complotter design.Adapter 11 " does not have annular projection, is manual Drawing Design.In addition, also can design different adapters as requested, form a cover.
Above-mentioned explanation only be an embodiment of the present utility model.Each part of the present utility model also can be other shape or with other form assembling.For example, Fig. 2 be a kind of biconial valve 4 and the valve seat 4 that adapts to it '.Fig. 3 be a kind of cylinder valve 4 and the valve seat 4 that adapts to it '.
Compare with the needle-tube drawing pen of existing use, Multifunctional needle tube drawing pen has following advantage:
1. owing to use the outflow of flow-limiting valve control ink, avoided leaking when the accident that nib leaves after writing thing, effectively stoped the drawing that causes thus to pollute.
2. owing to use the bidirectional guide pin, when the water conservancy diversion pin of an end is crooked, can rapidly the water conservancy diversion pin replacement of the other end be come, fix a breakdown.Thereby also prolonged the life-span of needle tubing pen.
3. owing to use spring to replace the gravity of weight to control the motion of water conservancy diversion pin, can make drawing pen operate as normal when becoming any angle with horizontal plane.
4. owing to be furnished with the different preceding end adapter of a cover, when this drawing pen is used for various objectives (manual operations or be used with various plotter), need only be simply changer adapter more, just can use, realized usefulness more than one.And make a large amount of manual drawing transfer instrumental drawing to, improved operating efficiency and quality greatly.
