Description

A kind of pen of handwriting pen tip band rubber

The utility model relates to a kind of stationery of the band rubber that is used to write, particularly a kind of pen of nib band rubber.

Need constantly seek rubber at people in the writing process and wipe this loaded down with trivial details phenomenon of clerical mistake, occur the pen of various afterbody band rubbers on the market.But this pen also exists drawback.Because of in case clerical mistake occurs, the writer must be with a plane Rotate 180 °, waits to wipe after the wrong part and handwriting must be continued to write behind the plane Rotate 180 ° once more again.Wipe twice rotation of the penholder that place clerical mistake causes and generally will incur loss through delay 4-6 second (do not contain and wipe the used time of person's handwriting).If this process repeats repeatedly, the time of waste is just considerable, and is particularly unfavorable to the examiner.

The purpose of this utility model just provides a kind of pen that can overcome the handwriting pen tip band rubber of above-mentioned shortcoming, can will wipe the time minimization of writing.

The utility model mainly is made of handwriting and the scraper that is arranged on the handwriting front end.In the scraper, the guider bottom is with spring, and the threaded portion of guider bottom passes in the hole of side shield in the precentrum semicanal.Rubber is arranged in half through hole of the scraper abut lower front end shaft of a writing brush, the distance of hole central axis and pen core axis is not more than 150 millimeters, one end of rubber is inserted in the rubber connector, the rubber connector then is screwed in the screw thread of guider bottom, when rubber was not released by user's forefinger, it was not more than 150 millimeters near the end face of front end shaft of a writing brush pen tip and the distance of front end shaft of a writing brush pen tip.The spin internal thread of guider major diameter one end of the externally threaded end of sliding button band.Scraper is connected with handwriting by connector.

The utility model can shorten the time of wiping clerical mistake greatly, can adopt nontoxic plastics, rubber etc. to make, and therefore can produce in a large number, and is with low cost, and can be made into the various complicated shapes that suit the requirements.

Fig. 1 is connected with the vertical view of the middle shaft of a writing brush upper end of scraper to nib in demonstration the utility model;

Fig. 2 is the A-A direction cutaway view of Fig. 1;

Fig. 3 is the structure cutaway view that is provided with the handwriting of scraper in the utility model;

Fig. 4 is the B-B direction cutaway view of Fig. 3.

Among the figure, the 1 front end shaft of a writing brush, 2 front end shaft of a writing brush pen tip, 3 rubbers, 4 precentrum semicanals, 5 rubber connectors, 6 half through holes, 7 baffle plates, 8 sliding trays, 9 springs, 10 guiders, 11 sliding buttons, 12 caps for brush, 13 scraper upper connectors, the 14 middle shafts of a writing brush, connector under 15 scrapers, 16 scrapers, 17 handwritings.

Below in conjunction with accompanying drawing the utility model is described in detail:

As shown in Figure 1, 2, handwriting 17 front ends connect the scraper 16 of a band rubber, and in the scraper 16, guider 10 bottoms are with spring 9, and the threaded portion of guider 10 bottoms passes in the hole of side shield 7 in the precentrum semicanal 4.Rubber 3 is arranged in half through hole 6 of the scraper 16 abut lower front end shafts of a writing brush 1, the distance of hole central axis and pen core axis is not more than 150 millimeters, the less end of the diameter of rubber 3 is inserted in the rubber connector 5, rubber connector 5 then is screwed in the screw thread of guider 10 bottoms, presses guider 10 large diameter ends and promptly is connected with the threaded one end of sliding button 11 after sliding tray 8 slides about 4cm.It was not more than 150 millimeters near the end face of front end shaft of a writing brush pen tip 2 and the distance of front end shaft of a writing brush pen tip 2 when rubber 3 was pushed out.Sliding button 11 is with the spin internal thread of guider 10 major diameters one end of an externally threaded end.Scraper 16 is connected with handwriting 17 by connector, and the upper and lower connector 13,15 at its two ends lays respectively between the cap for brush 12 and the middle shaft of a writing brush 14 and the middle shaft of a writing brush 14 and the front end shaft of a writing brush 1, and a circular hole is all arranged in the middle of two connectors.During use, only need rubber scraper connector is placed on respectively the two ends of the middle shaft of a writing brush 14, after the front end shaft of a writing brush 1, the cap for brush 12 were screwed on, scraper just can be connected with handwriting.

Rubber is positioned at by the pen core of the front end shaft of a writing brush, and sliding button is arranged on the Writer's forefinger place that holds a pen, so in case wrongly write, only need with forefinger to be about to rubber and to release from scraper along the moving button of nib direction sliding, the position of pen this moment in hand is constant all the time.Clean after the person's handwriting, only need unclamp forefinger, rubber will turn back to initial position rapidly, thereby the user can continue to write under the effect of spring (spring one end contacts all the time on the plate washer).

Figure 3 shows that another embodiment of the present utility model.In the present embodiment, scraper 16 utilizes screw to be connected with handwriting 17, can adopt four screws to be evenly distributed on the two ends up and down of precentrum semicanal 4 usually.
