Abstract
The utility model relates to a shock resistant pen core for a neutral ball-point pen, which comprises a ball, a ball seat and a connecting piece, wherein, the inside of the connecting piece is provided with a circle of convex ring formed a small hole, the diameter of which is smaller than the inner diameter of the connecting piece. If the utility model is met with shock during transporting and using, because the resistance of the convex ring, ink flows back. When passes through the small hole, the ink is blocked, and a flow rate decreases, which causes that countercurrent quantity is reduced, and a gap between a ball bead and ink which presses close to the ball bead can not be generated to stop flow, and therefore, normal writing is ensured.
Description
The utility model is the improvement about neutral ball pen, particularly about the impact-resistant structure of neutral ball pen.
It is lower that the printing ink that neutral ball pen is adopted is generally viscosity, if transportation or in use nib make when upwards being subjected to impacting printing ink in pen core tube rapidly reverse flow the former printing ink of being close to ball is shunk back backward, thereby make and produce an intersegmental crack (as shown in Figure 1, 2) between printing ink and ball, the printing ink cutout can not go out China ink at once when writing, and influence is normally write.
The purpose of this utility model is to solve the problem of existing neutral ball pen, designs a kind of impact-resistant pen core.
Formation of the present utility model comprises ball, pearl seat and connector, and the aperture that connector inside has a circle bulge loop to form, the diameter of this aperture is less than the connector internal diameter.
Fig. 1 is the contact condition schematic diagram of pen core ball and printing ink when not being hit;
Fig. 2 is that pen core is subjected to impacting the back ball and printing ink produces the view in gap;
Fig. 3 is a structure cut-away view of the present utility model.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Ball 1 is installed on the pearl seat 2, pearl seat 2 is flush-mounted on the connector 3, inwall at connector 3 is convexly equipped with a circle bulge loop 4, form an aperture 5, the diameter of this aperture is less than the internal diameter of connector 3, one section internal diameter of the connector 3 of script inner wall smooth is dwindled suddenly, and the diameter of the aperture that this bulge loop 4 forms is Φ 0.4～0.8mm, or its sectional area is 0.13～0.50mm
2
If meet and impact, be obstructed when the aperture because of the resistance of bulge loop 4 makes the printing ink adverse current in transportation or the process used, flow velocity slows down.The printing ink reflux flow reduces, and is close to the printing ink 6 of ball and can shrink back, thereby can not make and produce gap 7 between ball 1 and the printing ink 6 and the cutout influence is write.
The utility model has the advantages that connector inside sets up the aperture that bulge loop forms and improved The impact resistance of neutral ball pen has guaranteed normally writing of neutral ball pen.
Claims (2)
1. an impact-resistant neutral ball pen mainly comprises ball, and pearl seat and connector is characterized in that the aperture that connector inside has a circle bulge loop to form, and the diameter of this aperture is less than the connector internal diameter.
2. neutral ball pen according to claim 1, the hole diameter that it is characterized in that the formation of connector internal projecting ring are that the sectional area of Φ 0.4～Φ 0.8mm or aperture is 0.13～0.50mm
