Specific implementation mode
Hereinafter, to telescopic writing implement according to the present invention will in terms of its configuration and operation refer to the attached drawing it is detailed
Carefully it is described.
Fig. 2 is the exploded perspective view for showing telescopic writing implement according to the present invention, and Fig. 3 is shown according to the present invention
The pen tube of writing implement and the cross-sectional view and Fig. 4 of pen tip fixing device be that telescopic book according to the present invention is shown
Write the stereogram of the use state of tool.
As shown in Fig. 2, telescopic writing implement according to the present invention generally comprises：Main body cover 100, slideably
The pen tube 130 be inserted into main body cover 100 and accommodate the pen tip fixing device of pen tip 160 simultaneously in pen tube 130
150。
First, main body cover 100 can use injection moulding or mold molding side by synthetic resin material or metal material
Method is made, and can have hollow pipe or tubular form.
Main body cover 100 can be formed by one or two shell, and in illustrative examples, and two shells are by making
It is fastened and is coupled to each other with screw or interference fit.One conical shell can have the open front 102 being formed in one end.
In addition, retained part 110 may be mounted on the circumferential surface with 102 opposite side of open front of main body cover,
Retained part 110 is connected to main body cover to allow it as the basic clamping and release operation of clamping device.
Further, it presses and can be installed adjacent to retained part 110 by part 120, press and be mounted on main body cover by part 120
In 100, make pen tip 160 that open front 102 is stretched out or be retracted into from open front 102 will pass through bulldozing operation.
It presses and may be mounted in main body cover by part 120, to transfer force to pen by the bulldozing operation of user
Pipe 130, and there is tubular form, which has the small-diameter circular perimeter surface and large-diameter circular weekly form for being formed as stratiform
Face.Here, one end of small-diameter circular perimeter surface is opened, and the other end of large-diameter circular perimeter surface is closed.
Meanwhile pen tube 130 corresponds to ink-storing portion, and can be with the internal capacity of predetermined volumes, pen tube 130
It is inserted into main body cover 100 together with spring 140.
Tank section 132 of this pen tube 130 with maximum gauge, with relatively small straight of the diameter than tank section 132
The coupling part 133 of diameter and pen tip outrigger shaft part 134 with the relatively small diameter of the diameter than coupling part 133,
Middle tank section 132, coupling part 133 and pen tip outrigger shaft part 134 are reduced with its diameter towards pen tip together according to priority
When cambial mode be integrally formed.
Further, pen tip 160 is connected to the end of pen tip outrigger shaft part 134 by pen tip fixing device 150 so that
It can be according to the common Supply Method corresponding to writing implement type, by common ink feed method (for example, capillary is existing
As, pressure difference, sucking etc.), by any content (for example, ink etc.) being stored in tank section 132 from tank section 132
It is supplied to pen tip 160.
In addition, the stepped portion 136 with predetermined length can be by from the pen tube coupled with pen tip fixing device 150
The inner wall of 130 end is prominent and is formed.
The spring 140 being inserted into main body cover 100 together with pen tube 130 can be placed in the close storage tank of coupling part 133
On the scalariform face of part 132, thus to support.
Hereafter, spring 137 plays in axial direction pushes pen tube 130 in the stroke distances of pen tube 130 during operation
Effect.
For example, when pen tube 130 and press move scheduled stroke distances along forward direction by part 120 when, spring 137 is pressed
Elasticity can be restored wherein simultaneously for contracting, and when spring returns to extension state from compressive state, it is extensive which can be used as elasticity
Multiple power.Here, the predetermined stroke distance of pen tube 130 is equal to the stroke distances pressed by part 120, or is equal to initial position and pen
Point 160 is from the distance between position that it is stretched out.In addition, when pen tube 130 and press be in them by part 120 can be along rearward
To return release conditions when, it includes pressing by part that spring 137, which plays make to be connected to pen tube 130 by its elastic restoring force,
120 component returns to the effect of initial position.
Pen tip fixing device 150 can use injection moulding or die molding method by synthetic resin material or metal material
It is made, and hollow cylinder can be formed as, pen tip 160 is passed through and is contained in pen tip fixing device 150.
Pen tip fixing device 150 includes the coupling part 152 being integrally formed with one side, and coupling part 152 has direction
The predetermined length that the diameter of pen tube 130 reduces, to be inserted.Coupling part 152 have in axial direction cut with it is outer
The air circulation duct 153 of portion's connection.
In addition, at least one of air circulation duct 153 can be formed in coupling part 152, it is preferable that one
Facing with each other is formed as to air circulation duct 153, and its length is identical as the entire length of coupling part 152.
Further, coupling part 152 can be with the scalariform slot 154 of diameter formed therein, with reduction.Scalariform
Slot 154 can coordinate with the stepped portion 136 of pen tube 130, to prevent the separation between them.
In addition, coupling part 152 can be formed to have the outer diameter more slightly larger than the internal diameter of stepped portion.The reason is that inserting
During entering pen tube 130, due to cutting air circulation duct 153, the diameter of coupling part 152 can flexiblely reduce temporarily.
Hereinafter, by the telescopic writing implement according to the present invention with above-mentioned configuration with reference to figure 3 and Fig. 4 descriptions
Pen tip extend and retract operation.
When assembling writing implement, pen tube 130 and spring 140 are located in the inside of main body cover 100, and press by part
120 are fastened to one end of pen tube 130 with such as tight fit or the coupling method fastened with screw.
Then, pen tip fixing device 150 is connected to one end of pen tube 130, and pen tip 160, which passes through and is contained in pen tip, fixes dress
It sets in 150.
At this point, when being inserted into pen tip fixing device 150 by tight fit, executes and be inserted into pen tube 130, and coupling part
152 diameter flexiblely reduces due to cutting air circulation duct 153.After the insertion, the scalariform slot of coupling part 152
154 can coordinate with the stepped portion 136 of pen tube 130, to prevent the separation between them.
Meanwhile the coupling part 152 with the diameter reduced can more firmly fix pen tip 160 to a certain extent,
To prevent pen tip 160 from detaching.
In addition, as indicated by the arrows in fig. 3, it can be logical by being connected to the air circulation of the coupling part 152 of pen tube 130
Road 153 executes air circulation naturally, and even if is also in this way, due to air when using writing implement as shown in Figure 4
Circulation canal 153 is not exposed to outside, therefore can provide beautiful appearance, and is always protected by preventing foreign matter from being introduced into
Hold the steady-state cycle of air.
Further, in the present invention, pen tip is rather than directly into the side of pen tube 130 by pen tip fixing device 150
Method is connected to pen tube 130 so that pen tip 160 can use any nib style (such as, felt nib, roller point, writing brush point, modeling
Material pen tip or needle point) pen tip fixing device 150 be assembled into same main body cover 100, but regardless of its shape or type.
Although describing the present invention by reference to preferred embodiment and improved example, the present invention is not limited to above-mentioned
Specific embodiment and improved example, and it will be understood by those of skill in the art that not departing from by appended claims
In the case of the scope of the invention of restriction, can with various modifications and variations have been made in the present invention, and should not with the present invention
Technical spirit and foreground dividually understand these modifications and variations.
