Abstract
The utility model relates to a writing brush with a telescopic writing brush head, which comprises a writing brush head and a writing brush holder. The utility model is characterized in that the writing brush holder is hollow, and a writing brush head telescoping mechanism which is composed of a telescopic link, a rotating tube and a positioning tube is arranged in the writing brush holder; the writing brush head is fixed at the front end of the telescopic link, and the outer wall of the telescopic link is at least provided with a convex column; the rotating tube is sheathed outside the telescopic link, a longitudinal slim groove is arranged in the position corresponding to the convex column of the telescopic link, and the tail end of the rotating tube is fixed with a writing brush tail which is positioned outside the tail end of the writing brush holder; the positioning tube is sheathed outside the rotating tube and fixed at the inner wall of the writing brush holder, and a helical groove is arranged on the tube wall of the positioning tube along a longitudinal direction; the convex column of the telescopic link passes through the slim groove of the rotating tube and extends into the helical groove of the positioning tube. The writing brush head can be telescoped freely by adopting the scheme, and accordingly, the utility model has the advantages of convenient carrying and beautiful appearance.
Description
The utility model relates to a kind of writing brush, the telescopic writing brush of particularly a kind of nib.
Writing brush is as a kind of writing implement, and its shape, structure do not have much variations for a long time.Traditional writing brush generally is made up of nib, penholder, not using for ease of carrying, also also adds a pen cap at pen head part.Because this writing brush is not when using, the pen cap is enclosed within nib and penholder head, and nib all is soft with the pen cap, penholder is very long again, in carrying, because multiple former thereby cause nib distortion, and other article of may making dirty, as school bag, pocket etc., bring inconvenience in use.
The purpose of this utility model be the defective that exists at above-mentioned traditional writing brush and provide a kind of and be easy to carry, the written telescopic writing brush of profile uniqueness.
Scheme of the present utility model is: the telescopic writing brush of this nib, comprise nib, penholder, and it is characterized in that: described penholder hollow is provided with the written telescoping mechanism that is made of expansion link, tube, positioning pipe in it; Described nib is fixed on the front end of expansion link, and the outer wall of expansion link is provided with a projection at least; Described tube is enclosed within outside the expansion link, and has elongate slot longitudinally in the projection position of corresponding expansion link, and the tail end of a tube tail outer with being positioned at the penholder tail end fixes; Described positioning pipe is enclosed within outside the tube, and fixes with the penholder inwall, and positioning pipe longitudinally has helicla flute on tube wall; The elongate slot that the projection of described expansion link passes tube stretches in the helicla flute of positioning pipe.
Adopt such scheme just can make the brush writing skill retractable, be easy to carry, good looking appearance.

Fig. 1 is structural representation of the present utility model (part is analysed and observe);
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Fig. 3 is the utility model parts expansion link structural representation (analysing and observe);
Fig. 4 is the utility model parts tube structural representation (analysing and observe);
Fig. 5 is the utility model parts stationary pipes structural representation (analysing and observe);
Fig. 6 is the utility model parts stationary pipes structural representation;
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the telescopic writing brush of this nib comprises nib 3 and penholder 4, and penholder 4 is.Hollow structure is provided with a written telescoping mechanism in penholder 4, this mechanism is made of expansion link 5, tube 7 and positioning pipe 6.Wherein expansion link 5 is positioned at the inside, outwards is tube 7, positioning pipe 6 and penholder 4 successively from the lining, and its matching relationship as shown in Figure 2.
Expansion link 5 is arranged on tube 7 inner chambers, and one end internal diameter is bigger, and nib 3 is installed, and other end diameter is less, is provided with a projection 51 at least on its outer wall, as shown in Figure 3.Described projection 51 is preferably disposed on the tail end of expansion link 5, and has two, so that operation.
Outside the expansion link 5 is tube 7, as shown in Figure 4.Have the vertical elongate slot 71 corresponding with projection 51 on the tube 7, match with two projections 51, elongate slot 71 also is two.Described two projections 51 pass two elongate slots 71.
One end of two elongate slots 71 that described tube 7 is provided with respectively has a side channel 72, and when expansion link 5 drive nibs 3 were stretched out outermost, two projections 51 of expansion link 5 one ends just were stuck in the side channel 72, and expansion link 5 can not bounced back automatically.One end of described tube 7 is provided with flange 73, and the purpose of offering flange is to prevent that tube 7 from producing from positioning pipe 6.Positioning pipe 6 is shown in Fig. 5,6, it is fixed on the inwall of penholder 4, on positioning pipe 6 walls, have helicla flute 61 longitudinally, the projection 51 of expansion link 5 passes the elongate slot 71 of tube 7 and stretches in the helicla flute 61, for matching with two projections 51, the also corresponding twin-feed spiral groove 61 that has in positioning pipe 6, as shown in Figure 6.In addition, positioning pipe 6 can not be provided with specially yet, but helicla flute 61 directly is engraved in the penholder inwall, equally can realize the purpose of the utility model yet.
The tail end of penholder 4 is provided with a tail 2, and it and tube 7 are fixedly connected, and a rotation tail 2 can drive tube 7 and rotate.
When using the telescopic writing brush of this nib, take off the pen cap 1, earlier and hold penholder 4, on the other hand a tail 2 clockwise directions are rotated.Tube 7 in the penholder 4 is rotated, tube 7 drives expansion link 5 by two projections 51, make expansion link 5 clockwise directions stressed, this moment, two plush coppers 51 were just slided along the twin-feed spiral groove 61 of positioning pipe 6, thereby nib 3 and expansion link 5 are before pushed away, nib 3 is stretched out, and it is similar with traditional writing brush that nib is stretched out the back.Counter-rotating then makes nib 3 contract to penholder 4, covers the pen cap 1 then.
