The comprehensive ball pen comprises a pen cap tube, a pen cap clip setting on the end of pen cap tube, an eraser arranged on the end of pen cap, a pen tube imbedded at the bottom of pen cap, a pen-fill arranged in pen cap, a pen-fill cap tube arranged at the bottom of pen tube and make pen-fill expose; the end of pen cap tube forms a groove comprising roller; the roller contacts rubber to squeeze, position, push and move the rubber.

Description

Compound ball pen with erasing rubber pen cap

Technical field

The utility model belongs to writing implement, particularly a kind of Compound ball pen with erasing rubber pen cap.

Background technology

Comprehensive its erasing rubber of pen that the two ends of commonly using are respectively ball pen and erasing rubber is a solid form, can't upgrade, and can't make erasing rubber stretch out the use of pen cap pipe, or regain protection.

Summary of the invention

The purpose of this utility model provides the Compound ball pen with erasing rubber pen cap that a kind of volume is little, reusable, serviceability is good.

The utility model comprises pen cap pipe, be sheathed on pen cap tube end pen cap folder, be embedded at pen cap tube end erasing rubber, be inserted in pen cap pipe below the shaft of a writing brush, be placed in ball pen core in the shaft of a writing brush and the pen core sleeve pipe that is mounted on shaft of a writing brush lower end and makes the ball pen core stretch; Pen cap tube end formation group is established the groove of roller; Roller contacts with the extruding location and pushes mobile erasing rubber with erasing rubber.

Wherein:

Roller forms rough external surface, which is provided with the kingpin hole of diameter greater than the steady pin diameter; Pen cap pipe groove both sides are provided with pin-and-hole; The pen cap be folded with pen cap pipe on the corresponding pin-and-hole of pin-and-hole; The pen cap folder that is mounted on the roller in the pen cap tube end groove and is sheathed on pen cap tube end is hubbed in the pen cap pipe groove respectively by the steady pin that inserts pen cap barrel bolt hole, pen cap clamp pin hole and roller kingpin hole and is fixed on the pen cap pipe.

Pen cap tube end and pen cap folder are corresponding opening ring-type.

Because the utility model comprises pen cap pipe, be sheathed on pen cap tube end pen cap folder, be embedded at pen cap tube end erasing rubber, be inserted in pen cap pipe below the shaft of a writing brush, be placed in ball pen core in the shaft of a writing brush and the pen core sleeve pipe that is mounted on shaft of a writing brush lower end and makes the ball pen core stretch; Pen cap tube end formation group is established the groove of roller; Roller contacts with the extruding location and pushes mobile erasing rubber with erasing rubber.When adjusting the erasing rubber collapsing length, the roll extrusion rotation roller drives the erasing rubber displacement by the frictional force between increase of roller rough surface and the erasing rubber, to stretch out or the pen cap pipe of withdrawing; When desire was used erasing rubber, inwardly squeezing roller with the extruding erasing rubber, can not squeezed back in the pen cap pipe it by counter-pressure.Not only volume is little, reusable, and serviceability is good, thereby reaches the purpose of this utility model.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model comprises the roller 11 that forms rough external surface 12, pen cap pipe 21, pen cap folder 31, erasing rubber 41, the shaft of a writing brush 51, ball pen core 61 and the pen core sleeve pipe 71 that the end forms groove 22.

Roller 11 is provided with the kingpin hole 13 of diameter greater than steady pin 19 diameters.

Both sides, pen cap pipe 21 grooves, 22 place are provided with pin-and-hole 23.Pen cap pipe 21 ends are the opening ring-type.

Pen cap folder 31 is and the corresponding opening ring-type in pen cap pipe 21 ends, which is provided with pen cap pipe 21 on pin-and-hole 23 corresponding pin-and-holes 32.

The shaft of a writing brush 51 two ends are respectively a tail 52 that is closed and the anterior end of pen 53 that is provided with external screw thread 531, and its central section diameter is greater than a tail 51 and the anterior end of pen 53 at two ends.A tail 52 of the shaft of a writing brush 51 and anterior end of pen 53 are convexly equipped with

convex ring edge

54,55 respectively, can be tightr when guaranteeing to be inserted in the pen cap pipe 21 and the cap for brush 81.

Pen core sleeve pipe 71 is cone shape, which is provided with internal thread 72 corresponding with the shaft of a writing brush 51 anterior end of pen 53 external screw threads 531 and that be spirally connected.

Roller 11 is put into pen cap pipe 21 end recesses 22, pen cap folder 31 is inserted in from pen cap pipe 21 belows, press from both sides 31 pin-and-holes 32 and roller 11 kingpin holes 13 with steady pin 19 insertion pen cap pipes 21 pin-and-holes 23, the pen cap again, be fixed on the pen cap pipe 21 roller 11 is hubbed in pen cap pipe 21 grooves 22 and with pen cap folder 31; Erasing rubber 41 clamp-oned with roller 11 by pen cap pipe 21 tops contact, and by roller 11 kingpin holes 13 diameters greater than steady pin 19 diameters, be beneficial to the contact force of adjusting between roller 11 and the erasing rubber 41, can easily erasing rubber 41 be clamp-oned in the pen cap pipe 21, and be squeezed back by counter-pressure can prevent that erasing rubber 41 from using the time; Insert the below of pen cap pipes 21 with a tail 52 of the shaft of a writing brush 51, again ball pen core 61 is inserted in the shaft of a writing brush 51, at last with pen core sleeve pipe 71 screw locks on the shaft of a writing brush 51 anterior end of pen 53 external screw threads 531, make the tail end 62 of ball pen core 61 and nib 63 not be resisted against being a closed tail 52 and protruding out pen core sleeve pipe 71 of the shaft of a writing brush 51.

As shown in Figure 3, when adjusting erasing rubber 41 collapsing lengths, rotation roller 11 drives erasing rubber 41 displacements by the frictional force between roller 11 rough surfaces, 12 increases and the erasing rubber 41, to stretch out or the pen cap pipe 21 of withdrawing; When desire is used erasing rubber 41, inwardly press pressing roller 11, with extruding erasing rubber 41, it can not squeezed back in the pen cap pipe 21 by counter-pressure.

As Fig. 4, shown in Figure 5, a tail 52 of the shaft of a writing brush 51 has been put into pen cap pipe 21, and the tail end 62 of ball pen core 61 is put into pen cap pipe 21 with the shaft of a writing brush 51, and a tail 52 of the shaft of a writing brush 51 is exposed to outside the pen cap pipe 21, and the nib 63 of ball pen core 61 protrudes out outside the pen core sleeve pipe 71.
