Abstract

The utility model discloses an erasable pen. The erasable pen comprises a pen holder and an erasable head, wherein a cylindrical dent is formed in the lower end of the pen holder in the axial direction of the pen holder, and a through hole I is formed in the middle of the cylindrical dent; the erasable head is made of flexible plastic and comprises a hemispherical erasable head body and a connecting sleeve which are integrally formed, a through hole II is axially formed in the middle, the connecting sleeve and the cylindrical dent are identical in size, and the connecting sleeve is clamped in the cylindrical dent. According to the erasable pen, the erasable head is made of the flexible plastic and integrally connected with the lower end of the pen holder, so that the erasable pen cannot be abraded and loosen; during usage, all that is required is to retract a refill into the pen holder and then directly erase paper with the erasable head, the paper cannot be damaged, and the erasable pen is delicate in structure and worth popularizing.

Description

A kind of erasable pen

Technical field

The utility model relates to the technical field of structures of pen, refers to especially a kind of erasable pen.

Background technology

Erasable pen adopts special ink, is generally divided into erasable ball pen, erasable gel ink pen, erasable pen etc., main feature be its writing within a certain period of time available common rubber clean, there is the erasable advantage of pencil.The principle of erasable pen is that ink adopts temperature sensitive ink, and friction generates heat back and forth makes its volatilization or bleach of being heated for rubber, realizes the effect that writing disappears.Erasable pen in use must be by rubber, therefore be easy to use, together with rubber is arrived with penholder integrating, common way is the draw-in groove that accommodating rubber is set on the cap for brush, main technological deficiency is, rubber easily comes off to cause and uses inconvenience on the one hand, rubber is running stores on the other hand, and the writing time of pen core is longer, can not erasing after there will be rubber to be used up the situation of notes, in addition, common telescopic pen core formula gel ink pen or ball pen at present, penholder upper end is all that Manual press head is set, and is not suitable for placing erasing rubber.

Utility model content

The purpose of this utility model is to provide a kind of rubber erasable pen that do not use, simple in structure, easy to use.

For realizing the purpose of this utility model, intend by the following technical solutions:

An erasable pen, is characterized in that: comprised penholder with can rubbing head, described penholder lower end edge penholder axially arranges tubular depression, the middle part of tubular depression is set to through hole one; Described can rubbing head be made by flexiplast, comprised hemispherical rubbing head and branch sleeve, hemispherical rubbing head and branch sleeve are made as one, and its middle part arranges through hole two vertically, the sizableness of the size of branch sleeve and tubular depression, branch sleeve is fastened in tubular depression.Can rubbing head and penholder by being fastened, connect as one, pen core can be to external extension from through hole one, while needing erasing to revise after writing, by in pen core indentation penholder, use hemispherical rubbing head on person's handwriting, to carry out wiping, through friction generates heat, according to the self-characteristic of ink, person's handwriting erasing can be fallen.

As preferably, described tubular depression is combined to form by outer sleeve and inner sleeve are concentric, can the external diameter of rubbing head branch sleeve suitable with the internal diameter of outer sleeve, the internal diameter of branch sleeve is suitable with the external diameter of inner sleeve, when branch sleeve injects in tubular depression, with the tight blocking of inner sleeve outer sleeve, avoid rubbing head getting loose.

As preferably, described can rubbing head be made by TPR material (Thermo-Plastic-Rubber material, the meaning is thermoplastic elastomer material), more soft than penholder material, is convenient to when friction generates heat, be unlikely to scratch paper.

Compared with prior art, the rubbing head of the utility model wiping person's handwriting is made by flexiplast, and connect as one in penholder lower end, can not wear and tear and can not get loose simultaneously, during use, only pen core need be taken in penholder, then using can the direct wiping of rubbing head, can not damage paper, delicate structure, is worthy to be popularized.

Accompanying drawing explanation

Fig. 1 is the utility model example structure figure;

Label in figure is: 1, penholder; 2, tubular depression; 21, outer sleeve; 22, inner sleeve; 23, through hole one; 31, hemispherical rubbing head; 32, branch sleeve; 33, through hole two.

The specific embodiment

Below in conjunction with drawings and Examples, further illustrate the technical solution of the utility model:

In conjunction with Fig. 1, penholder 1 lower end of the utility model embodiment erasable pen arranges outer sleeve 21 and inner sleeve 22, and outer sleeve 21 and inner sleeve 22 arrange with one heart and form tubular depression 2, and the middle part of inner sleeve 22 arranges through hole 1, and through hole 1 is flexible for the yearning of pen core.Can rubbing head be made by TPR material, hemispherical rubbing head 31 and branch sleeve 32 have been comprised, hemispherical rubbing head 31 is made as one with branch sleeve 32, its middle part arranges through hole 2 33 vertically, can the external diameter of rubbing head branch sleeve 32 suitable with the internal diameter of outer sleeve 21, the external diameter of the internal diameter of branch sleeve 32 and inner sleeve 22 be suitable, when branch sleeve 32 injects in tubulars depression 2, with the tight blocking of inner sleeve 22 outer sleeve 21, avoid rubbing head getting loose.During use, pen core is taken in penholder, by hemispherical rubbing head 31, on person's handwriting, carry out wiping, through friction generates heat, according to the self-characteristic of ink, person's handwriting erasing can be fallen.
