Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the overall structure schematic diagram of lettering pen of the present utility model;
Fig. 2 is the A portion enlarged drawing of lettering pen of the present utility model;
Fig. 3 is the structural representation of valve member of the present utility model.
The specific embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model relates to a kind of lettering pen, comprises the penholder 1 of hollow, and penholder 1 inside is provided with valve member 4, valve member 4 is divided into ink-containing chamber 2 and chamber out of ink 3 by the penholder of hollow 1 inner chamber, is provided with the agitation beads 5 opening and closing for promoting valve member 4 in ink-containing chamber 2.
In chamber 3 out of ink, be equipped with lower ink assembly 7.
One end away from nib 75 of lower ink assembly 7 is provided with partition seat 74, and valve member 4 is inserted in one end towards ink-containing chamber 2 of partition seat 74.
Valve member 4 has the valve seat 41 of hollow, and valve seat 41 is axially penetrated with for the first through hole 42 and the second through hole 43 for ink flow successively along the direction away from ink-containing chamber 2.The spring 45 that valve member 4 also comprises valve lever 44 and is placed in valve seat 41 inside; Valve lever 44 comprises the first valve lever 46 and second valve lever 47 of coaxial setting, between the first valve lever 46 and the second valve lever 47, be also provided with flange 48, the second valve rod 47 and flange 48 are placed in valve seat 41 inside, and the free end of the first valve lever 46 is placed in the outside of valve member 4 and is placed in ink-containing chamber 2 through the first through hole 42.One end of spring 45 is sheathed on the second valve lever 47, and is connected to flange 48 end faces; The other end of spring 45 is connected to valve seat 41 inwalls.
In the first through hole 42, be also provided with Valve plug 49 against flange 48 places, Valve plug 49 be sheathed on the first valve lever 46 and with the first valve lever 46 interference fit.The shape of Valve plug 49 is along the frustum reducing gradually towards ink-containing chamber 2 orient diameters.The first through hole 42 is suitable with Valve plug 49 shapes.
By spring 45 is set, flange 48 can be pushed on the first through hole 42, thereby and Valve plug 49 be matched with the first through hole 42 make the ink that is placed in penholder 1 not flow into valve seat 41 inside from penholder 1, flow into further in lower ink assembly 7.When needs are used lettering pen, only need to rock agitation beads 5, can promote valve lever 44 along moving away from the direction of ink-containing chamber 2, can make Valve plug 49 depart from and the contacting of the first through hole 42, thereby ink is flow in valve seat 41 from the first through hole 42, further by the second through hole 43, flow in lower ink assembly 7, for writing.When not stirring, valve lever 44, towards the direction motion near ink-containing chamber 2 under the effect of spring 45 elastic force, makes Valve plug 49 and the first through hole 42 match again.
Be understandable that, agitation beads 5 adopts stainless shot, can under the effect of less power, promote valve lever 44 and move, but agitation beads 5 also can adopt such as the agitation beads 5 that is other materials such as iron shot.In the effect of the state lower spring 45 not stirring elastic force by compression, be not less than the gravity sum of agitation beads 5, valve lever 44 and Valve plug 49, thereby make under the state not stirring, thereby can not push valve lever 44 open and open valve member 4 because of the Action of Gravity Field of agitation beads 5.
The shape of flange 48 has no particular limits, preferred, adopts the annular flange flange 48 being extended radially outwardly by the first valve lever 46, can be also the flange 48 of square-shaped flange 48 or other shape.
The internal diameter of the second through hole 43 is less than the external diameter away from ink-containing chamber 2 one end of spring 45; Spring 45 is connected to the inward flange of the second through hole 43.
The shape of spring 45 is edge towards the shape increasing gradually away from ink-containing chamber 2 orient diameters, owing to from the second through hole 43, valve lever 44 being inserted in valve seat 41 in installation process, therefore the diameter of common the second through hole 43 is greater than the diameter of the first through hole 42, the diameter of the second valve lever 47 is also less than the diameter of the second through hole 43, spring 45 is in order to adapt to the size of the second valve lever 47 and the second through hole 43 and in order to make spring 45 be tightly placed in the second valve lever 47 outsides, spring 45 adopts the shape that above-mentioned diameter increases gradually.
Valve member 4 be placed in partition seat 74 or interference fit be inserted in partition seat 74.
In the utility model, select to adopt valve member 4 to be placed in the mode in partition seat 74, concrete, in valve seat 41 arranged outside, there is the first projection that is no less than, in partition seat 74 inner sides, second projection suitable with the first projection is set, by the first projection, protruding intersect adjacent setting with second, the maximum outside diameter of the first projection is greater than the minimum diameter of the second projection, and the first projection is placed in the side away from ink-containing chamber 2 of the second projection, again by will the end of valve seat 41 and the end of partition being connected, can realize valve member 4 is placed in to partition seat 74 inside tightly.
Concrete, lower ink assembly 7 also comprise and penholder 1 coaxial arrange be inserted in the pen cap 73 in penholder 1, one end towards ink-containing chamber 2 of the pen cap 73 is also plugged with nib 75, nib 75 is passed the pen cap 73 and is inserted in partition seat 74 simultaneously.
Nib 75 is outer is also surrounded with sponge 72, for receiving the ink being flowed into by ink-containing chamber 2, and offers nib 75 for writing.
Preferably, be inserted in the pen cap 73 to partition seat 74 interference fit.
Be understandable that, valve member 4 and partition seat 74, the connected mode of partition seat 74 and the pen cap 73 also can the alternate manner such as screw by screw thread and realize.
To sum up, by the valve member 4 that can open and close under the effect of agitation beads 5 is set, can when not needing lower ink assembly 7 ink supply, prevent that ink from flowing backwards, needs during to lower ink assembly 7 ink supply by stir agitation beads 5 just can to make ink flow into lower ink assembly 7 in to write.
This lettering pen is pen with ink, is understandable that, the structure of this lettering pen is also applicable to water writing pen, oiliness lettering pen, comprises various white board markers, marking pen, watercolor pencil and cosmetic pencil etc.
By reference to the accompanying drawings embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, also can make a lot of forms, within these all belong to protection of the present utility model.
