Abstract
The utility model relates to an improved structure of a one-ball type pen point of neutral ball-point pen. The structure consists of a ball, a ball seat, the body of the ball seat and a groove in the ball seat, and is characterized in that when the diameter of the ball is 0.5mm, the inside diameter of the groove is 0.25mm to 0.3mm and the outside diameter of the groove is 0.45mm to 0.49mm; when the diameter of the ball is 0.4mm, the inside diameter of the groove is 0.2mm to 0.25mm and the outside diameter of the groove is 0.35mm to 0.39mm; and the clearance between the ball and the ball seat is 0.025mm to 0.045mm, and the optimized size is 0.032mm to 0.040mm while the inside wall of the ball seat forms a plurality of stepped holes. The utility model has the advantages that the structural is rational, the precision of matching is high, and the writing is smooth.
Description
Technical field
The utility model relates to a kind of ball pen head, especially relates to a kind of improvement of one-ball type pen point of neutral ball-point pen structure.
Background technology
As everyone knows, the ball pen that people use is that ink is put in the ink barrel of tubulose, and makes it to flow out from nib.The ink that is used for this type of ball pen, in order not leak and drying, irritating mostly has oily ink, and feel was bad when oily ink was write, and is not good with respect to the stability of temperature.For this reason, a kind of Neutral writing ink between oiliness and water-based has appearred on the market, reach ball pen with Neutral writing ink, Neutral writing ink can be used as to write needs the long preservation data time spent, its effect is equal to water-base ink, adopt low viscosity ink to improve as gel ink pen is first and the China ink amount, but many negative issues have also been produced simultaneously, volatilize easily as ink, China ink group will appear in stop slightly for a long time on paper, therefore, use high viscosity inks to become the development trend of neutral ball pen, but neutral ball pen does not reach the best goes out China ink amount, therefore, follows closely and the structure of the pen point of neutral ball-point pen that comes and the assurance of quality of fit also just become key point.
Summary of the invention
The utility model mainly is to solve existing in prior technology: the technical problem of the structure of pen point of neutral ball-point pen and the assurance of quality of fit etc. goes out the China ink amount to reach the best.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: have ball, ball seat, ball seat body, the inside of ball seat has groove, with pearl footpath φ 0.5mm, the ditch internal diameter is φ 0.25mm-φ 0.30mm, and the ditch external diameter is φ 0.45mm-φ 0.49mm; With pearl footpath φ 0.4mm, the ditch internal diameter is φ 0.2mm-φ 0.25mm, and the ditch external diameter is φ 0.35mm-φ 0.39mm.
As preferably, the gap of ball and ball seat is 0.025mm-0.045mm.
As preferably, the gap of ball and ball seat is preferably 0.032mm-0.040mm.
As preferably, ball seat body internal diameter is set as the shoulder hole that several dwindle step by step.
Therefore, the utlity model has rational in infrastructurely, the quality of fit height is write along characteristics such as cunnings, smoothness.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is that the ball of Fig. 1 cooperates enlarged diagram with ball seat;
Accompanying drawing 3 is Fig. 2 groove structure schematic diagrames.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the method for ink that goes out of neutral ball pen is a method of utilizing gravity principle and capillary principle to combine.As shown in Figure 1 to Figure 3, there is groove 4 ball seat 2 inside, and in fact groove 4 is equivalent to capillary, take 3 among the embodiment, can be 3 to 8 in actual the use, when the groove of ball seat 2 inside with pearl footpath φ 0.5mm, the ditch internal diameter is φ 0.25mm-φ 0.30mm, φ 0.45mm-φ 0.49mm; With pearl footpath φ 0.4mm, the ditch internal diameter is φ 0.2mm-φ 0.25mm, and the ditch external diameter is φ 0.35mm-φ 0.39mm; Ball 1 is 0.025mm-0.045mm with the gap of ball seat 2.Ball seat body 3 adopts stainless steel, and internal diameter is set as several shoulder holes that dwindles step by step, to improve the smoothness that China ink.Above-mentioned processing is full-automatic disposable the finishing of written special-purpose machining center.
