Description
Technical field
The utility model is about a kind of automatic pencil structure, but refers to the propelling pencil heart module of a kind of Rapid Combination in pen especially.
Background technology
In No. 498860 " modularity automatic pencil structure " preceding cases of Chinese T W patent announcement, a kind of modularity automatic pencil structure is provided, after making that the propelling pencil core structure is able to the modularity combination, be fit into again and push in the pen, push pen and separate production and provide, to raise the efficiency and various variation is arranged in pairs or groups with propelling pencil heart module.
In the modular structure of preceding case, it comprises: a main body 2, it is one to be the hollow form body of step shape, these main body 2 one ends are provided with an outward extending writing end 21, set the damping 215 of a hollow in its openend after, embed a relay pipe 216 again; Main body 2 other ends then are provided with a press-side 23, in addition pen core tube 25 1 ends and press-side 23 sockets that can ccontaining pen core in this main body 2, and forming interlock, the other end then is provided with a conveying device 26 adjoining writing end 21 1 sides, so that the conveying pen core.In the penholder 31 by a push type ballpoint pen 3 that this main body is packed into, make its writing end 21 be placed in the writing portion position of penholder 31, press-side 23 then is connected the press section 33 in penholder 31, when pushing the press section 33 of penholder 31, the press-side 23 of body 2 impels pen core tube 25 and conveying device 26 synchronization actions, so that with the transmission of the pen core in the pen core tube 25 by conveying device 26, and by relay pipe 216, and be damping 215 clampings, in order to do the writing portion that one section pen core is exposed to penholder 31.
And this conveying device in this module comprises: one holds pipe 28, is embedded in the pen core tube 25, can pass through for pen core; One elasticity recovery element 29 is socketed on pen core tube 25 1 ends; One bronze medal bundle pedestal 210, be fixedly arranged on hold the pipe 28 and writing end 21 between, it offers an opening; One bronze medal bundle 211 is embedded in the opening of copper bundle pedestal 210 movably; One movable claw 213, pass through and ccontaining copper bundle 211 in, make movable claw 213 in addition end embed the openend of pen core tubes 25, and with hold pipe 28 and join; When mat pen core tube 25 suffers external force, be compression reaction flexible member 29, and force hold pipe 28, movable claw 213 and copper bundle 211 produces relative displacements, when copper bundle 211 touches body 2 inwalls and stops to move, 213 lasting displacements of movable claw are also outwards opened, so that carry pen core.
Yet, in case structure before this, because main body 2 is hollow form bodys of a step shape, element in combination transfer device 26 holds pipe 28, elasticity recovery element 29, copper bundle pedestal 210, copper bundle 211, movable claw 213, damping 215 etc., it is very difficult anabolic process, cost a lot of money man-hour, the reduction of unfavorable cost remains to be improved.
Summary of the invention
The utility model purpose is, a kind of propelling pencil heart module is provided, and to overcome the defective of above-mentioned traditional structure, makes part simplify, and can assemble fast.Simultaneously, have at part and damage or when incorrect, also can disassemble correction fast, significantly to reduce manufacturing cost.
A kind of propelling pencil heart module provided by the utility model, it is combined in the push type propelling pencil sleeve pipe; It is characterized in that, comprising:
One pen core tube has the inner space that can accommodate several Zhi Bixin, and its bottom has an inside and is the portion that dwindles of tapered channel;
One movable claw structure has the passage that can pass through for a pen core, and the top is to stretch into above-mentioned stationary pipes of dwindling the portion bottom, and the below is a corpus unguis that is made of the several calvus that scatter;
One tube connector is straight-tube shape, and its bottom has the threaded portion of contracting in, and has a bronze medal bundle in this bottom, threaded portion, and this copper Shu Shu is on the corpus unguis of above-mentioned movable claw structure, and this tube connector inside has a break difference structure in order to a ccontaining spring; And
One bottom tube, upper interior has internal thread, and the threaded portion of itself and above-mentioned tube connector locks together, and in its bottom combination one damping piece is arranged, and the passage in this damping piece matches with pen core;
Above-mentioned connecting piece and bottom tube are fixed on to be pushed in the pen; And the portion that dwindles of above-mentioned pen core tube stretches into above above-mentioned tube connector and is pressed on the upper surface of above-mentioned spring.
Wherein, the pen core tube top is provided with a rubber stopper in order to the sealing opening.
Wherein, the rubber stopper of pen core tube is outside equipped with a top cover in order to this rubber stopper of capping.
The utility model beneficial effect: by said structure, the utility model makes part simplify, and can assemble fast.Simultaneously, have at part and damage or when incorrect, also can disassemble correction fast, significantly to reduce manufacturing cost.
Below, will structure of the present utility model and effect be described in detail according to the embodiment shown in the drawing.
Description of drawings
Fig. 1: be stereo appearance figure of the present utility model,
Fig. 2: be exploded view of the present utility model,
Fig. 3: be cutaway view of the present utility model,
Fig. 4: be that the utility model practical application is assembled in the schematic diagram of pushing pen,
