Abstract
The utility model relates to a triangular push-pull type eraser comprising a tube body, a cover body, an eraser core and a propeller, wherein the tube body is provided with a core outlet; the tube wall is provided with an elongated slot; the side of the elongated slot with a sawtoothed slot notch; one end of the eraser core movably sheathed in the tube body is fixedly arranged on the propeller; a push button positioned on the propeller spans over the elongated slot and is positioned outside the tube body; the cover body closes the propeller in the tube body; the triangular push-pull type eraser is characterized in that the eraser core has a narrowly equilateral triangular prism structure, the narrowly triangular prism eraser has three sharp edges, and can generate more edges for the need of erasing by being matched with grooves on all prism surfaces, thus being very suitable for erasing tiny pencil characters. For the triangular push-pull type eraser, the structural design is reasonable, the rigid tube body is used for protecting the eraser core, and the handheld operation is more stable, and breaking or dirty of the eraser core are avoided; and the push-pull design is adopted, a user can operate by a single hand, thus being flexible and convenient.
Description
Technical field:
The utility model belongs to the stationery field, particularly a kind of plug-type erasing rubber of pen type with triangle erasing rubber core.
Background technology:
Erasing rubber is the quotidian stationery of people, and white appearance is in the majority, softness and high resilience.The white rubber is dust suction and absorbing sweat easily, and finger is affectedly bashful use, and that often does is surperficial dirty, and makes surperficial rubber rotten, influences service property (quality).For this reason, manufacturer works hard in packing, makes every effort to the protection to the rubber surface; at rubber outer wrapping one deck paper of finished product, then plastic packaging has film again, is the complete packing of product; protective when also being to use only needs the part to open the film of sealing with the person, and exposing rubber can be for having used.The font that pencil is write is generally less, and the erasing rubber that this kind structure is made often volume is bigger, it is the fillet shape that the rubber edges and corners often are easy to wearing and tearing, is difficult to accurately wipe the writing of the wiping of wanting, thus design a kind of have multangular erasing rubber research object of the present utility model.
Summary of the invention:
The purpose of this utility model is the plug-type erasing rubber of triangle that a kind of erasing rubber core of design has three corner angle and has body to protect outward.
Technical solutions of the utility model are achieved in that the plug-type erasing rubber of a kind of triangle, comprise body, lid, erasing rubber core and propeller, this body has a knockout mouth, and offer an elongated slot on the tube wall, the groove side of elongated slot is provided with serrated slot and lacks, be movably set in the interior erasing rubber core one end clamping of body on propeller, being positioned at push button on the propeller strides across elongated slot and is in outside the body, lid is enclosed in propeller in the body, it is characterized in that the erasing rubber core is equilateral class triangular prism structure, class triangular prism erasing rubber has three comparatively sharp corner angle, and Convenient scrubber removes tiny person's handwriting.
Each cylinder of described class triangular prism erasing rubber core has a groove parallel with corner angle, makes the erasing rubber core have more corner angle.
Described groove cross section becomes arc structure.
Described body becomes equilateral class triangular prism structure, and elongated slot is opened on the corner angle.
Described propeller front portion has a folder mouth, the rear portion downside is extended with one can be extended with an arc elastomer at slide plate, the upside that inboard wall of tube body slides, this elastomeric arc top cross is provided with can insert the thrust salient point of body serrated slot in lacking, vertically convex with a holding support, this holding support width is slightly less than body elongated slot width, and push button is set on this holding support.
Can conflict on inboard wall of tube body in the unsettled end of described propeller elastomer.
The serrated slot that the both sides of described body elongated slot are provided with symmetry lacks, and propeller elastomer arc top cross is arranged with the thrust salient point.
The utility model reasonable in design, by the body of rigidity protection erasing rubber core, hand-held is more sane, does not worry that the erasing rubber core fractures or dirty; Adopt plug-type design, user's one-hand operation, flexible; The design of erasing rubber core class triangulo column, corner angle are sharper keen, cooperate the groove of each cylinder, produce the need of more corner angle for wiping, are fit to very much the tiny pencil writing of wiping.

Fig. 4 propeller schematic perspective view
Wherein
1-body 11-elongated slot 12-serrated slot lacks
13-knockout mouth 2-erasing rubber core 21-corner angle
22-groove 3-propeller 31-slide plate
32-folder mouthful 33-elastomer 34-thrust salient point
35-push button 36-holding support 4-lid
The specific embodiment:
See figures.1.and.2, the plug-type erasing rubber of triangle comprises body 1, erasing rubber core 2, propeller 3 and lid 4, and its middle tube body 1, propeller 3 and lid 4 are by plastic shaping.1 one-tenth equilateral class triangular prism structure of body, elongated slot 11 is opened on the corner angle, two groove sides of elongated slot 11 are provided with serrated slot and lack 12, one end of body 1 has the slightly knockout mouth 13 of reducing, elongated slot 11 ends are the open ports that is used to install erasing rubber core 2 and propeller 3, and be equipped with lid 4, both are enclosed in the body 1.
With reference to Fig. 1, Fig. 2 and Fig. 4, propeller 3 front portions have the folder mouth 32 of an energy clamping erasing rubber core 2, the rear portion downside is extended with one can be at the slide plate 31 of inboard wall of tube body slip, upside is extended with an arc elastomer 33, the arc top cross of this elastomer 33 is provided with the thrust salient point 34 that can insert in the body serrated slot scarce 12, vertically convex with a holding support 36, these holding support 36 width are slightly less than body elongated slot 11 width, push button 35 is set on this holding support 36, the effect of holding support 36 is to guarantee that propeller 3 push pull maneuver are only along elongated slot 11 directions, do not deflect and do not produce, produce unnecessary resistance.Can conflict on body 1 inwall in described propeller elastomer 33 unsettled ends, guarantee that elastomer 33 has enough elastic force, when action advances device 3, need press down push button 35, the arc top of its compressing elastomer 33 of mat, reduce its height, the serrated slot that makes thrust salient point 34 break away from elongated slot lacks 12 restrictions, push-and-pull operation smoothly; Unload external force, under push pull maneuver trend, thrust salient point 34 is under the elastic force effect of elastomer 33, and the serrated slot that springs into nearby lacks 12, forms the location, uses or collection for wiping.
The serrated slot that the both sides of this example middle tube body elongated slot 11 are provided with symmetry lacks 12, and propeller 3 elastomer arc top cross are arranged with thrust salient point 34, and the location is steady more and reliable.
With reference to Fig. 3, described erasing rubber core 2 is equilateral class triangular prism structure, and each cylinder of class triangular prism erasing rubber core 2 has a groove 22 parallel with corner angle 21, and these groove 22 cross sections become arc structure.The design of groove 22 has increased the corner angle 21 of erasing rubber core 2, makes that itself and another corner angle spacing is dwindled again, forms new wedge angle, the facility that the wiping person's handwriting is provided capable of circulation after the corner angle 21 wipings wearing and tearing.
