Description

Flexible pen

The utility model relates to a tool, especially the flexible pen technology field of push type.

Variation along with scientific and technological progress and mankind's activity, make the development of a tool also be tending towards variation, and in many tools, the flexible pen of push type becomes a long lasting product, probe into its reason, be that the nib that is the push type ballpoint pen has the function of taking in voluntarily, and need not to mate separately cap, so there is not the ballpoint pen cap to lose, can't clamping carry or shortcoming such as black liquor pollution clothing.The flexible pen of tradition push type is according to the structure-improved report of Chinese patent ZL98207583.9 push-button type mechanical pencil, as shown in Figure 5, shaft of a writing brush top inner wall is vertically prominent on main one establishes some key ribs that separate with a determining deviation for it, it is to reach the middle rib tenon that slightly caves in therebetween by a left rib tenon and right rib tenon to be constituted, the oblique setting of each tool rib of the bottom of each rib tenon, and each key intercostal is opened a keyway, in order to prominent being embedded at respectively in each keyway and the middle rib tenon of the equidistant prominent some keys established in hollow cylindrical retainingf key bottom, make it only can upper and lower displacement, this retainingf key bottom tool is the upper gnawing tooth of height, so that the key lever of a rotation key inserts in the retainingf key, its upper gnawing tooth of establishing of dashing forward is to mesh each other with lower gnawing tooth, and it is some that the lower gnawing tooth outside is then set up the key rib separately corresponding to the keyway place, so that selectivity embeds in the keyway, inside and outside, rotation key bottom tool one keyhole, it can be connected with the pen core top is chimeric, and a pair of lug of being broken through on it is after offseting with the coil tension spring socket, so that press spring, then pen core and spring are together inserted in the following shaft of a writing brush of a tool pore, be connected with the last shaft of a writing brush with being about to start writing manage, and it is chimeric to stretch out the shaft of a writing brush outer a retainingf key and a pressure cap, promptly forms a push type ballpoint pen.Its shortcoming is pressed and is pressed telescoping mechanism complexity, especially retainingf key and the processing of rotation key working of plastics, and structure is complicated, inconvenient production and processing has size to cooperate difference a little, easily causes a flexible pressing mechanism malfunctioning, the long-time use because working of plastics weares and teares mutually, also easily makes shorten its service life.

The purpose of this utility model be to provide a kind of simple in structure, produce easily, the flexible pen of not easy to wear, long service life.

The technical solution of the utility model is to realize like this.It includes the shaft of a writing brush, the cap for brush is arranged at last shaft of a writing brush top, last shaft of a writing brush bottom is connected with the following shaft of a writing brush, the shaft of a writing brush forms middle cavity and is built-in with pen core up and down, has pressed spring between the pen core protuberance and the following shaft of a writing brush, it is characterized in that the shaft of a writing brush has a slide block in cap for brush lower cavity, slide block is connected with the depression bar that cooperates with last shaft of a writing brush surface chute, slide block also has the fixture block hole simultaneously, built-in little spring and fixture block, and fixture block matches with chute bottom, last shaft of a writing brush surface hole clipping.

Flexible pen of the present utility model is owing to adopt chute and fixture block structure, need not complicated retainingf key and rotation key, simplify the structure, each part also makes things convenient for production and processing, production cost is reduced, and parts are also difficult because of the structural design cause causes wear damage, and long service life suits to apply on a tool.

Below in conjunction with description of drawings embodiment of the present utility model is further described:

As shown in the figure, should include the shaft of a writing brush 1 by flexible pen, the following shaft of a writing brush 7, the cap for brush 3, pen core 5, spring 6, generally speaking, shaft of a writing brush cross section is rounded up and down, it is conical that following shaft of a writing brush bottom is, and outer surface is with garment bag, many frictions of garment bag distribution grooves, so that the writer to be provided the comfort sense that holds a pen, be connected or rotating being threaded for inserting the formula tight fit between the last shaft of a writing brush and the following shaft of a writing brush, form middle cavity up and down between the shaft of a writing brush, middle cavity is equipped with pen core 5, pen core is shaped on annular protrusion or lug, by having pressed spring 6 between protuberance or the lug and the following shaft of a writing brush, the pen core top is pressed with slide block 2 by intermediate mass 4 directly or indirectly, in order to make pen core that sufficient length be arranged, the slide block bottom has the cavity 23 of ccontaining intermediate mass, slide block is adaptive with shaft of a writing brush middle cavity shape size, and can freely slide up and down, shaft of a writing brush surface has chute 11 on the correspondence, the chute bottom is connected with rounded hole clipping 12 substantially, the hole clipping diameter is bigger than chute width, shoe surface has aperture 21, right rear loading type tight fit connects or the rotating depression bar 8 that is threaded and is fixed with the button spike, depression bar one end inserts in the slide block aperture for the microcephaly, the other end is a major part, can stretch out outside the shaft of a writing brush surface by hole clipping 12, cooperate with chute, press for people's hand, thereby drive refill expansion by slide block, slide block also has fixture block hole 22 below aperture, the fixture block hole is rounded, built-in short cylindrical bodily form fixture block 9, and the surface has the hole in the fixture block, make it become spring base 92 and adorn little spring 10, the fixture block outer surface has the spacing scrobicular ring face 91 that cooperates with hole clipping, and fixture block can be stretched under people's finger pressure power, can not eject hole clipping again, the fixture block surface is provided with by point 93, make things convenient for the writer to press fixture block with finger, it is spacing to make fixture block break away from hole clipping, makes pen core under spring action in the retraction shaft of a writing brush, the also slotting formula of the last shaft of a writing brush is tightly fixed or rotating being threaded is fixed with the cap for brush 3, has pen clip on the cap for brush.

Its operation principle is as follows: when writer's finger is depressed fixture block, because fixture block is under the finger pressure effect, overcome little spring elastic force, in the retraction hole clipping, thereby it is spacing to make fixture block break away from hole clipping, so pen core is below under the spring force effect, in the retraction shaft of a writing brush, and the drive slide block upwards moves its state diagram such as Fig. 2; When the writer points the pressure pressing lever, because depression bar drives slide block and moves down, pen core overcomes following spring force effect, stretches out outside the shaft of a writing brush, when aiming at hole clipping to fixture block, fixture block is under the little spring effect, eject part slightly, spacing down at spacing scrobicular ring face, lock slider, thereby make pen core can the retraction shaft of a writing brush in writing process yet in, its state diagram such as Fig. 3.
