Abstract
The utility model relates to a kind of nib for writing.The utility model is by the following technical solutions: a kind of nib, it is characterized in that: include metal tube and plastic wrapper, described plastic wrapper axle center is provided with through hole, described metal pipe sleeve is located in the through hole of plastic wrapper, one end of metal tube has part to appear formation pencil from the end of plastic wrapper, the top of the pencil of metal tube is provided with ball, and the other end of the relative pencil of described plastic wrapper is provided with shoulder rank.By adopting such scheme, the utility model overcomes the deficiency that prior art exists, and provides a kind of and saves material, novel nib easy to process.
Description
Technical field
The utility model relates to a kind of nib for writing.
Background technology
The nib of ball pen of the prior art or free ink pen is divided into two kinds, a kind of to be diameter be nib of 0.8 millimeter, a kind of to be diameter be nib of 2.3 millimeters, wherein diameter is the processing method of the nib of 0.8 millimeter is arrange hoodle manufacture again after the metal tube end being directly 0.8 millimeter to diameter processes, the method is very general at present, the method only has 0.8 millimeter due to the diameter of metal tube, so do not need to carry out reducing process in the end of metal tube in process, so relatively simple, and diameter be 2.3 millimeters nib due to its diameter thicker, so aforesaid way can not be adopted simply to process, the processing method of the nib of existing 2.3 mm dias first chooses the cylinder that diameter is 2.3 millimeters, then process respectively at two ends, through boring and cutting, the end of cylindrical member at one end is cut into taper shape, the axle center of the other end is drilled to hollow form, triangle star-shaped through hole or pentalpha through hole is washed into again bottom hollow form, finally put into hoodle, the shortcoming of the method is, 1, material is wasted in a large number, boring and cutting process after metal charge all waste, 2, operating efficiency is extremely low, produces cost very high.
Summary of the invention
The utility model overcomes the deficiency that prior art exists, and provides a kind of and saves material, novel nib easy to process.
To achieve these goals, the utility model is by the following technical solutions: a kind of nib, it is characterized in that: include metal tube and plastic wrapper, described plastic wrapper axle center is provided with through hole, described metal pipe sleeve is located in the through hole of plastic wrapper, one end of metal tube has part to appear formation pencil from the end of plastic wrapper, and the top of the pencil of metal tube is provided with ball, and the other end of the relative pencil of described plastic wrapper is provided with shoulder rank.
By adopting such scheme, we can save material greatly, so just can process 2.3 millimeters of thick nibs with the metal tube of 0.8 millimeter, very simple, convenient, we also can carry out the change of color to plastic bushing thus realize nib and have color in addition, are all the situation of single metallochrome before changing.
Further setting of the present utility model is: the through hole of described plastic wrapper is divided into ink opening and metal tube trepanning, the diameter of metal tube trepanning is greater than between ink opening, the joining place of metal tube trepanning and ink opening forms step, and after metal tube trepanning is inserted in described metal tube interference, conflict on step in its end; The maximum gauge of described plastic wrapper is 2.3 millimeters, the diameter of described metal sleeve is 0.8 millimeter, the pencil of described metal tube is provided with reducing inclined-plane, described plastic wrapper is positioned at pencil one end and is arranged to tapered portion, and the top of this tapered portion is connected with the reducing inclined-plane of metal tube.
By adopting above-mentioned further technical scheme, make the rational in infrastructure of this product, easy to process, metal pipe sleeve is located on plastic wrapper more firm.
Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 2 is the sectional view of the utility model embodiment;
Fig. 3 is the A portion enlarged drawing in Fig. 2;
Fig. 4 is the plastic housing sectional view of the utility model embodiment.
Detailed description of the invention
As shown in Fig. 1-Fig. 4, a kind of nib, include metal tube 1 and plastic wrapper 2, described plastic wrapper 2 axle center is provided with through hole 21, described metal tube 1 is set in the through hole 21 of plastic wrapper 2, one end of metal tube 1 has part to appear formation pencil 11 from the end of plastic wrapper 2, and the top of the pencil 11 of metal tube 1 is provided with ball 111, and the other end of the relative pencil 11 of described plastic wrapper 2 is provided with shoulder rank 22.By adopting such scheme, we can save material greatly, so just can process 2.3 millimeters of thick nibs with the metal tube of 0.8 millimeter, very simple, convenient, we also can carry out the change of color to plastic bushing 2 thus realize nib and have color in addition, are all the situation of single metallochrome before changing.
In the utility model embodiment, the through hole 21 of described plastic wrapper 2 is divided into ink opening 211 and metal tube trepanning 212, the diameter of metal tube trepanning 212 is greater than between ink opening 211, metal tube trepanning 212 forms step 213 with the joining place of ink opening 211, and after metal pipe sleeve 2 through hole 21 is inserted in described metal tube 1 interference, conflict on step 213 in its end; The maximum gauge of described plastic wrapper 2 is 2.3 millimeters, the diameter of described metal sleeve 1 is 0.8 millimeter, the pencil 11 of described metal tube 1 is provided with reducing inclined-plane 112, described plastic wrapper 2 is positioned at pencil 11 one end and is arranged to tapered portion 23, and the top of this tapered portion 23 is connected with the reducing inclined-plane 112 of metal tube 1.
