Abstract

A handwriting pen positioning structure is used to fix a handwriting pen of a personal digital assister. A buckle structure is equipped at the handwriting pen and comprises a pen slot and an elastic buckle. The pen slot is used to place the handwriting pen, while the elastic buckle is formed inside the pen slot. The elastic buckle further contains an elastic arm and a buckle section. When the handwriting pen is inserted, the buckle section can fit with a buckle equipped at the handwriting pen, so as to realize reliable buckling and positioning of the handwriting pen.

Description

Writing pencil screens structure

[technical field]

The utility model relates to a kind of personal digital aid (PDA), is meant a kind of writing pencil screens structure of personal digital aid (PDA) especially.

[background technology]

Follow development of science and technology, (Personal Digital Assistant PDA) becomes the important tool that people carry out information management to personal digital aid (PDA) gradually.Because be subjected to the restriction of volume, personal digital aid (PDA) does not have the keyboard of setting separately usually, but by writing pencil input message.For making writing pencil be convenient to pick and place, generally be to establish pen placing trough at the sidewall of personal digital aid (PDA) housing, rely on the friction force between a writing pencil and the groove to prevent that writing pencil from getting loose in a groove.Aforementioned schemes is relatively simple for structure, but there is the unsettled technological deficiency of friction confining force in it, friction force is bigger when promptly beginning, increase along with access times, a writing pencil and a groove will inevitably be worn, cause to each other that friction force reduces, as vibrations or be inverted, writing pencil then might come off from a groove.

At foregoing problems, occurred about the fixing new technical scheme of writing pencil: as notification number is the Chinese utility model patent of CN2501086Y (day for announcing is on July 17th, 2002), it discloses a kind of pocket or palm PC, it adopts on palm PC body and writing pencil correspondence position magnet is set respectively, by the fixing writing pencil of magnetic force.The retain strength that this kind technical scheme is provided is more constant certainly, but weak point is: if magnetic force is very little, then fixing not firm, magnetic force is too big, will certainly the sensitive electronic components on the palm PC internal circuit board be impacted.

[utility model content]

The purpose of this utility model be to provide a kind of simple in structure, fix reliably, and the internal circuit of personal digital aid (PDA) not have the writing pencil screens structure that influences.

The purpose of this utility model is achieved in that a kind of writing pencil screens structure, fixes the location in order to the writing pencil to personal digital aid (PDA), comprising: a groove, and its length and writing pencil are suitable, to accommodate writing pencil; Elastic buckle, L-shaped, it further comprises an elastic arm and grab, when writing pencil inserted, this grab can fall into draw-in groove set on the writing pencil, thereby realized the reliable snaps into position of writing pencil.

Writing pencil screens structure of the present utility model only promptly realizes the reliable fixing of writing pencil is located by simple structure such as elastic arm and grab.In when assembling, can save in the existing structure because of there being the necessary assembly process of a plurality of elements, can show the saving cost.

[embodiment]

Please in conjunction with reference Fig. 1 and Fig. 2, personal digital aid (PDA) has housing 2 and writing pencil 4, and housing 2 one sides are provided with a groove 21, and the length of this groove 21 is suitable with writing pencil 4, and writing pencil 4 can insert in the groove 21 when not using.In order to prevent that writing pencil 4 from skidding off in a groove 21, at the one-body molded flexible buckle 22 of the sidewall of a groove 21, after writing pencil 4 inserted, this Elastic buckle 22 can be clasped with the annular slot 44 of setting on the writing pencil 4.In addition, be provided with protuberance 41, so that writing pencil 4 is taken out from the insertion position on writing pencil 4 tops.

Please in conjunction with reference Fig. 3 and Fig. 4, have rectangular opening 23 on a groove 21 sidewalls, Elastic buckle 22 is positioned at rectangular opening 23, and and rectangular opening 23 sidewalls between leave the gap.Set Elastic buckle 22 is L-shaped, and it further comprises grab 24 and elastic arm 26, and grab 24 projects upwards in a groove 21 inner wall surface, and elastic arm 26 is then roughly concordant with a groove 21 inwalls.Make writing pencil 4 when inserting, by the elastic force of elastic arm 26, grab 24 can fall into the draw-in groove 44 of writing pencil 4.Be provided with additional ribs 28 in addition on the sidewall relative with grab 24, it can support an other side of the draw-in groove 44 of writing pencil 4, and then improves the screens effect.

In use, with the protuberance 41 of hand extrapolation writing pencil 4, elastic arm 26 produces elastic deformation, and makes the releasing that is clasped of grab 24 and draw-in groove 44, and writing pencil 4 can take out.

Be appreciated that also can put than fine positioning fin (not shown) is set, and projecting upwards in grab 24 correspondences of a groove 21 inner wall surface of former Elastic buckle 22 changed into groove (not shown), can realize the purpose of the invention equally at writing pencil 2 leading portions.
