A pen frame is added in the existing drawing pen with the connective structure of a pen head, a pen body, a pen reservoir tube and a pen reservoir tube sleeve; the bottom of the pen frame has a tapered opening and internal threads. The whole drawing pen is fixed on a drawing machine through the pen frame. The drawing pen can compare beauty with import drawing pens. The utility model has the advantages of high drawing quality, strong applicability to paper, low cost, easy fabrication and a great deal of foreign exchange saving for countries.

Description

Neede type drawing pen for drawing machine

The utility model relates to a kind of draught machine pin type ruling pen, and it belongs to the drawing instrument that computer-aided design (CAD) is used.

At present, the employed ruling pen of pen type plotter has two types, i.e. ball-type and needle point formula.Ball-type ruling pen and ball pen are similar, and as nib, owing to be subjected to the restriction of ball size, nib is thicker with ball, and the first stroke of a Chinese character, stop pen and change pen place lines inhomogeneous, can not draw out high-quality map; The pin type ruling pen is to be nib with needle tubing, and nib is thin, and setting-out is even, but this kind nib of domestic use is basically from external import, and its shortcoming one is the price height, needs the consumption foreign exchange; Another is the requirement height of this kind pen to paper, and general tracing paper and blank sheet of paper result of use are not good, thereby cause the computer mapping cost to be much higher than manual drawing cost, and this is to promote the obstacle that CAD draws.

The purpose of this utility model provides a kind of drawing quality height,, pin type ruling pen that cost low strong to paper adaptability.

The purpose of this utility model is achieved in that it is made up of reservoir tube 1, bile duct cover 2, a body 3 and nib 5, in addition penholder 4: internal thread is arranged at a body 3 bottoms, and there is external thread at the middle part, in exhaust, diversion passage are arranged; Body 3 tops are reservoir tube 1 in succession, and the bottom is nib 5 in succession; There is step in the reservoir tube openend outside, and bile duct cover 2 is fastened on reservoir tube 1 on the body 3 with screw thread by this step, and makes between a reservoir tube 1 and the body 3 airtight; Penholder 4 bottoms have one to become leakproof fit bell with a nib neck of 5; In screw thread is arranged; Nib 5, a body 3, reservoir tube 1, bile duct cover 2 insert in the penholder 4 after being assembled into roman, and the internal thread of the external thread of a body 3 and penholder 4 is spirally connected fixing.Body 3 combines as a whole with penholder 4, and internal thread is arranged at the bottom, and step is arranged at top.

Because adopt such scheme, effect of the present utility model can match in excellence or beauty with the import ruling pen, and is better than domestic known ruling pen; Less demanding to paper, can be applicable to normal transparent plotting paper and drawing blank sheet of paper, and solve the water blockoff problem of nib; In addition, price is very cheap, has only 1/35～1/40 of import pen.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 7 is the another kind of profile synoptic diagram of embodiment 2.

Fig. 8 is that embodiment 3(is applicable to Calcomp series draught machine pen) the profile synoptic diagram.

Fig. 9 is the sectional structure chart of embodiment 3.

Among the figure: 1. reservoir tube, 2. bile duct cover, 3 bodies, 4 penholders, 5. nib, 6. a body penholder association.

Static structure: three kinds of embodiment of the present utility model include reservoir tube 1, bile duct cover 2, a body 3, penholder 4 and nib 5.First embodiment and second embodiment (seeing Fig. 1～7) are applicable to Hp, Roland, HI three big serial pen type plotters, its concrete structure is: a body has internal thread in 3 bottoms, be used for the device nib, directly insert in the reservoir tube 1 outer end, top, in the body 3 one exhaust-diversion passage is arranged, make between reservoir tube and the nib to keep clear by this passage; There is a step in the reservoir tube 1 openend outside, and bile duct cover 2 is fastened on body 3 tops with screw thread with bile duct by this step, and makes between a bile duct and the body airtight.Penholder 4 bottoms have one to become leakproof fit bell with a nib neck of 5, when the integral body of nib, a body, bile duct, bile duct cover formation is inserted penholder 4, this mouthful has auxiliary fixation to it, and this integral body is to be fixed on the internal thread of penholder 4 by the external thread on the body 3.This assemble sequence is: nib places a body bottom by self screw thread, body inserts reservoir tube and the bile duct cover is fixing, the integral body that they are constituted screws in the penholder 4 again, drawing ink places in the bile duct, exhaust-diversion passage by a body, enter in the water receiver of nib 5, under the effect of penstock pin, draw by nib.

The 3rd embodiment (Fig. 8,9) is applicable to Colcomp series draught machine, it by the nib 5 of common manual pin type ruling pen, be contained in a lower end of body penholder association 6.Internal thread is arranged at body penholder association 6 bottoms, is used for device nib 5, and directly insert in the reservoir tube 1 in the drive fit mode outer end, top, and one exhaust-diversion passage is arranged in the association, and this passage makes between reservoir tube 1 and the nib 5 and keeps clear.This assembling is: nib places in the bottom of body penholder association by self screw thread, and association inserts in the reservoir tube upper end, and the drawing ink exiting water process is same as the previously described embodiments.

The penholder 4 of present embodiment 1,2 can adopt the cap of old HI penholder button and the manual ruling pen of heroic 71A pin type to form and make, the penholder 4 of embodiment 3 can adopt the cap of old Roland penholder bottom, heroic 71A to make, can make full use of the original equipment of a factory, so it is technology is simple, with low cost.
