Abstract

The utility model relates to a ball pen with a moveable eraser, which is composed of the moveable eraser and a ball pen. The ball pen with a moveable eraser has the functions of the eraser and the ball pen. An eraser core of the moveable eraser is movable, and can be pushed out one section when one section is used up. After the whole eraser core is used up, a new eraser core can be replaced to continuously be used. The utility model is convenient for students to learn.

Description

Ball pen with movable eraser

The utility model is the movable ball pen of wiping skin of band that a kind of suitable student learns to use.

The erasable ball pen of writing, because it had both saved Wood-bar pencil and need roll up the trouble of cutting, overcome the defective of propelling pencil lead for retractable pencil frangibility again, the main study that will progressively replace pencil and become students in middle and primary schools is with pen, if mix the movable skin of wiping, then can provide bigger convenience to student's study to it.

The purpose of this utility model is to design a kind of ball pen with movable wiping skin, its movable wiping core-skin of wiping skin is movable, it can release a joint again after using up a joint, the replaceable new wiping core-skin in back that exhausts continues to use, and provides convenience for the student wipes writing.

Ball pen with movable eraser is made up of movable eraser and ball pen two parts.The wherein movable skin of wiping is mainly formed by wiping core-skin, wiping core-skin sleeve, sliding plug and sliding plug impeller.Wiping core-skin is that cylindrical is wiped skin, it is contained in the sliding plug groove, sliding plug then is contained in to be wiped in the core-skin sleeve, promote the sliding impeller of filling in, just can make sliding the plug in sleeve, rise or descend, thereby drive is wiped the core-skin rising or descended, make the wiping core-skin after using up a joint, can release again a joint, after a remaining trifle can not be used, it can be transferred to, be loaded on new wiping core-skin and continue to use.The structure of ball pen part is then similar with existing ball pen.

The utility model provides convenience for student's study, and has protective action owing to wipe the core-skin sleeve to wiping core-skin, because repeatedly using fatigue fracture takes place so can avoid wiping core-skin.

Enforcement of the present utility model mainly contains dual mode, and a kind of mode is to make sliding plug make up and down rectilinear motion in wiping the core-skin sleeve, successively releases or the retraction sleeve will wipe core-skin one; Another kind of mode is to make sliding plug make spiral in wiping the core-skin sleeve to rise or descend, and successively releases or the retraction sleeve will wipe core-skin one.At this, only a kind of mode is the specific implementation of the ball pen of example oolemma movable eraser in the past.

Accompanying drawing is the ball-point pen structure schematic diagram with movable eraser.Wherein, Fig. 1 is front view (analysing and observe), and Fig. 2 is side view (analysing and observe).

As shown in drawings, be made up of movable eraser and ball pen two parts with the ball pen of movable eraser, movable eraser is contained in the ballpoint holder upper end.Wherein, movable eraser department forms by wiping core-skin 1, wipe core-skin sleeve 2, slide plug 3 and sliding plug impeller 4.Wipe core-skin for thick about 7mm, be about the cylindrical wiping skin of 40mm; Wipe core-skin sleeve inboard with two straight runners 5, be provided with a sliding hole 6 every 5mm on the chute, the sleeve front has a straight trough 7, and sliding plug impeller can move up and down along this straight trough; One cylindrical aperture is arranged at the bottom of sliding plug 3, and spring 8 is housed in the hole, and both ends of the spring respectively is equipped with a submissile pearl 9, and a rectangular opening 10 is arranged above spring, and this hole is used for fixing sliding plug impeller; There are four symmetrical fins 12 the cell wall inboard of the cunning plug groove 11 of sliding plug 3, and its effect is to make to wipe core-skin and insert tight behind the sliding plug groove and be difficult for becoming flexible.The right side, upper end of the pen container 13 of ball pen part has a U type groove 14, the left side has slide fastener draw-in groove 15, piston 16 is made of one with pen button 17, elasticity slide fastener 18, when promoting the pen button downwards along U-lag, the moving piston of cingulum is released pen core 19, the elasticity slide fastener springs in the circular port of slide fastener draw-in groove bottom simultaneously, and pen core is locked in the release state.When mounted, earlier spring is packed into and slide in the cylindrical aperture of plug, be loaded on little hoodle, from the two straight runners of wiping core-skin sleeve bottom with hoodle alignment sleeve inboard sliding plug is pushed in the sleeve, and will slide the plug impeller by fixing in the sliding plug of the sleeve straight trough insertion rectangular opening, then movable eraser is installed in the ball pen upper end and screws, namely install.When the wiping core-skin of packing into new, wiping core-skin alignment sleeve need only be put forth one's strength to push also to compress in the sliding plug groove in the sleeve and get final product, after the wiping core-skin uses up a joint, can promote sliding plug impeller will wipe core-skin and release a joint again (when sliding plug moves to place, sliding hole, hoodle is sprung into sliding hole, the difficult promotion of sliding plug this moment, sliding plug just can not slide when using the wiping skin to wipe spot like this), after the wiping core-skin uses up, the out of use part of being left can be transferred to, be loaded on new wiping core-skin and continue to use.

Claims
