1. The novel pen point is marked with a hollow cylindrical tube 1 and a hollow round head 2 with a shape like a firm thumb tip.

2. The hollow round head 2 is marked with a smooth and bright 'water drop-shaped' inclined plane 3 at the edge, a capillary seam nozzle (ink outlet) 4 with two long edges and front and back tips turning smoothly and brightly, a smooth and bright part 5 except the 'water drop-shaped' inclined plane 3 and the capillary seam nozzle 4, an area (in an oval dotted line frame) 6 contacted with a writing surface, and an ink supply channel 7 with the distance between the two long edges in the seam nozzle gradually reduced.

Technical Field

The invention belongs to a novel pen point device.

Background

At present, the production technology of selling gel ink pen nib on the market is complicated, and the nib structure almost all comprises steel ball and bowl seat, and no innovation has increased manufacturer's manpower, material resources and financial resources again, and when this nib was write the position and is received exogenic action, the steel ball was impaired easily or drops, leads to writing not smooth.

Disclosure of Invention

The technical scheme shows that: the pen point is simple in production process, simple in structure and free of assembly, the pen point is of a single integral structure, and the pen point has a good effect on solving the background technical problems. It is marked with a hollow cylindrical tube 1 and a hollow round head 2 with the shape like a stiff thumb tip, as shown in figure 1 (three-quarter side plan view). The hollow round head 2 is marked with a smooth and bright 'water drop-shaped' inclined plane 3 at the edge, a capillary seam nozzle (ink outlet) 4 with two long edges and front and back tips turning smoothly and brightly, a smooth and bright part 5 except the 'water drop-shaped' inclined plane 3 and the capillary seam nozzle 4, an area (in an oval dotted line frame) 6 contacted with a writing surface, and an ink supply channel 7 with the distance between the two long edges in the seam nozzle gradually reduced.

The drop-shaped inclined plane (in the circular broken line frame) of the front side plan view (figure 2) of the pen point is changed into a bright smooth arc-shaped edge 8 with the front and back shapes completely superposed, which corresponds to the three-quarter side plan view and is shaped like a firm thumb 9; the front plane view (figure 3) of the pen point can see a water drop shape on the front, which is an inclined plane, and the edge of the water drop-shaped inclined plane is smooth and bright; the top of the front and back plan view (figure 4) of the pen tip can also see an extension of the capillary slit nozzle 4, which is an ink outlet, and is a slit combined with the capillary slit nozzle 4; the pen tip is seen from a front bottom plan view (fig. 5), looking inside the plane from the bottom, with the circular tube wall 10, and the slit 11 inside the ink feed channel 7, which slit has a central widest dimension in the range of 0.05 mm.

The wall thickness of the whole hollow round head 2 is equal to that of the hollow cylindrical pipe 1, and the hollow round head is relatively hard. The falling on the ground is not easy to break due to the influence of non-subjective human factors. The two sides of the capillary seam nozzle on the drop-shaped inclined plane are gradually inclined, smooth and bright from the writing surface 6 and are turned to the area 12 in the ink supply channel. The two long sides and the front and rear tip turning points 13 of the whole sewing nozzle are smoothly and brightly treated, and the turning points are neat and regular and have no grooves or bulges.

Detailed Description

A full-needle type gel ink pen filled with ink is found, a full-needle type pen point is taken down, a new pen point is inserted, the tail area (the area opposite to the pen point) of the pen is held by a hand, the pen body is thrown slightly, and the pen can write after the pen point slightly discharges the ink.
