Abstract

A telescopic pen has an oil core telescopic mechanism, a penholder, a rail, a snap cover and a snap fastener, characterized in that the said oil core telescopic mechanism is rack-and-pinion. The telescopic pen of the utility model adopts the rack-and-pinion mechanism to effectively increase the oil core telescopic trip, and the total length of the whole pen is shortened without prejudice to the use, and the pen is easy to carry.

Description

Flexible pen

Technical field

The utility model relates to a kind of flexible pen, relates in particular to a kind of pinion and rack that adopts and makes the flexible pen of nib motion.

Background technology

In the market the kind of the flexible pen of backward rotation and quantity all seldom, they adopt lever principle mostly.Its shortcoming is that flexible stroke is short, and the head apicule, is inconvenient to carry.Therefore wishing has flexible stroke long, and the new varieties pen that is convenient for carrying occurs.

The utility model content

It is long that the purpose of this utility model provides a kind of flexible stroke, and the flexible pen of the new varieties that are convenient for carrying, and it can shorten the length overall of pen effectively under the situation that does not influence use.

The technical scheme that realizes the utility model purpose provides a kind of flexible pen, and it has wick telescoping mechanism, penholder, guide rail, presses cover and presses cap, it is characterized in that described wick telescoping mechanism is a pinion and rack.

Described pinion and rack has one first tooth bar and one second tooth bar and places a gear between described two tooth bars, this gear is fixed in an axis also can be around this rotation in the described guide-track groove, first tooth bar and second tooth bar insert guide rail respectively synchronously from two ends, guide rail inserts and presses in the hole of cover, the front end of first tooth bar contacts with the wick assembly, second tooth bar inserts interior the fixing of bayonet socket of top cap, and the top cap inserts to press in the cover and fixes, and the internal and external threads of penholder and guide rail links together.

In described wick assembly, there is a little spring to be enclosed within on the wick, described wick cover for seat is at the afterbody of wick, and this three puts into the hole of point cover together, and the elasticity button on the wick seat inserts in the groove of point cover.

The specific embodiment

In conjunction with the accompanying drawings to after the embodiment explanation, can clearer and more definite understanding be arranged below to advantage of the present utility model and characteristics.

Fig. 1 is the separation member stereogram of an a kind of flexible embodiment of the utility model, and the installation step ， And that introduces a kind of flexible pen of the utility model below in conjunction with this figure understands an a kind of flexible example structure of the utility model therefrom.The first step: little spring 04B is enclosed within on the wick 01, wick seat 05 is enclosed within on the afterbody of wick, when again this three being put into together the hole of point cover 02, the elasticity button on the wick seat 05 is inserted in the groove of point cover 02.After the assembling, pressing wick Zuo Time will make wick stretch out penholder 03 like this.

It is fixing with gear 07 and guide rail 10 with axis 08 then gear 07 to be put into guide-track groove 10 ， And, but gear is that the pine cover cooperates, can rotate around this axis with axis.After first tooth bar 06 and second tooth bar 09 inserted synchronously from the two ends of guide rail 10 respectively, again guide rail is inserted in the bayonet socket that inserts top cap 12 in the hole of pressing cover 11, with second tooth bar fixing, then this top cap is inserted press in the cover 11 fixing.

Again big spring 04B is enclosed within after part that point cover 02 Shang And assembles with the first step is contained in penholder 03 hole, the internal and external threads of penholder 03 with guide rail 10 linked together.So just finished the assembling of whole flexible pen.

When holding penholder 03 with one, another pulls and movingly presses 11, top cap 12 is along A direction Yun Dong Time, and top cap 12 drives second tooth bar and rotates along A direction Yun Dong And driven gear 07.Gear 07 rotation makes first tooth bar move to the B direction, and first tooth bar has driven wick, sharp cover and wick seat to B direction motion Tong Time and also stretched out penholder to B direction Yun Dong And, thereby finishes wick and the sharp motion that of stretching, the state shown in arrival Fig. 2 A of overlapping.If hand moves round about, the wick, And that just withdraws turns back to state shown in Figure 2.

From top explanation as can be known, the flexible pen of the utility model is real adopts a pinion and rack to strengthen the flexible stroke ， And of wick effectively to shorten the length overall of lump-sum and be easy to carry under the situation that does not influence use.

Claims

1, a kind of flexible pen, it has wick telescoping mechanism, penholder, guide rail, presses cover and presses cap, it is characterized in that described wick telescoping mechanism is a pinion and rack.

2, flexible according to claim 1 pen, it is characterized in that, described pinion and rack has one first tooth bar and one second tooth bar and places gear between described two tooth bars, this gear is fixed in an axis also can be around this rotation in the described guide-track groove, first tooth bar and second tooth bar insert guide rail respectively synchronously from two ends, guide rail inserts and presses in the hole of cover, the front end of first tooth bar contacts with the wick assembly, it is interior fixing that second tooth bar inserts the bayonet socket of top cap, the top cap inserts to press in the cover and fixes, and the internal and external threads of penholder and guide rail links together.

3, as flexible pen as described in the claim 2, it is characterized in that in described wick assembly, having a little spring to be enclosed within on the wick, the wick cover for seat is at the afterbody of wick, and this three puts into the hole of point cover together, and the elasticity button on the wick seat then inserts in the groove of point cover.
