For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model provides a replaceable tool of writing pen core, comprises the shaft of a writing brush and the movable written assembly that is sticked in said shaft of a writing brush lower end, is inserted with the pen core of writing that can be used for writing in the said written assembly.
In the utility model, can be connected with multiple written assembly engaging on the shaft of a writing brush of a tool, like this, can satisfy the multiple requirement of writing type of user's needs, the functional diversities of this tool, easy to use.
Below in conjunction with concrete accompanying drawing detailed description is carried out in the realization of the utility model.
Embodiment one
Shown in Fig. 1～3, a preferred embodiment that provides for the utility model.
In the present embodiment; Tool 1 comprises the shaft of a writing brush 11 and is movably fastened the written assembly 12 in this shaft of a writing brush 11 lower ends; Be provided with in this nib assembly 12 and write pen core 13; Here " being movably fastened " refers to: the user can be fixed written assembly 12 in the lower end of the shaft of a writing brush 11, certainly, also can the lower end of written assembly 12 from this shaft of a writing brush 11 be disassembled.Like this; When the user need write; Can write with the pen core 13 of writing on this tool 1, and when the user need other type write pen core 13 time, then can be through rotating written assembly 12; The end of whole written assembly 12 from the shaft of a writing brush 11 disassembled, change the written assembly 12 of writing pen core 13 with needs.
The shaft of a writing brush 11 of the tool 1 in above-mentioned can be connected with multiple written assembly 12 engagings respectively; And the pen core 13 of writing in each written assembly 12 is different, like this, and through changing different written assembly 12; The user can be implemented in the dissimilar written assembly 12 of use on the same shaft of a writing brush 11; Thereby satisfy the multiple requirement of writing, the functional diversities of this tool 1, it is also convenient to use.
In the present embodiment, writing pen core 13 is pencil-leads, and the written assembly 12 in above-mentioned comprises following written 121 and the pushing mechanism 125 that is placed on the shaft of a writing brush 11 that is movably fastened on the shaft of a writing brush 11 lower ends nib 112, places written 112 lower ends; Have first cavity volume in the last nib 112, have second cavity volume in the following nib 121, have the 3rd cavity volume in the shaft of a writing brush 11; Like this, the 3rd cavity volume of the shaft of a writing brush 11, go up first cavity volume of nib 112 and down second cavity volume of nib 121 formed the cavity 14 that is used to place pushing mechanism 125, that is to say that pushing mechanism 125 is to be placed in the cavity 14 of nib 112, nib 121 and the shaft of a writing brush 11 formation down; Pencil-lead is located in pushing mechanism 125, goes up in nib 112 and the following nib 121, and nib 121 is provided with first through hole that is communicated with cavity 14 down, and pencil-lead can pass the outside through this first through hole; One end of pushing mechanism 125 is fixedly connected on down on the nib 121; Following nib 121 can be rotated on last nib 112, thereby, because last written 112 rotation; Can drive pushing mechanism 125 and promote moving of pencil-lead; Thereby, when the user when using tool 1 of configuration pencil-lead, it can nib 121 realizes moving of pen cores through rotating down; After the pencil-lead use is over, directly just can first through hole of new pencil-lead through following nib 121 be penetrated down in the nib 121.
In order to realize the annexation that is movably fastened between the nib 112 and the shaft of a writing brush 11, inwall of nib 112 is provided with first snap rings 123 on this, and the inner surface of this first snap rings 123 is provided with first projection; Accordingly, the lower end of the shaft of a writing brush 11 is provided with engaging body 111, and this engaging body 111 can be plugged in first snap rings 123; And the outer surface of this engaging body 111 is provided with the chute 113 that first projection that can supply first snap rings 123 slides, and these chute 113 upper ends extend to form the breach 114 that can cooperate with first projection around engaging body 111 outer surfaces one side, like this; When nib 121 needs and the shaft of a writing brush 11 cooperate instantly, directly will descend the shaft of a writing brush 121 to be inserted on the above-mentioned shaft of a writing brush 11 lower ends, and first projection on first snap rings 123 slide along engaging body 111 lip-deep chutes 113; Until an end of chute 113 formation breach 114, so far, can be with descending nib 121 to rotate along the side that chute 113 forms breach 114; Thereby; First projection of first snap rings 123 is fastened in the breach 114 that chute 113 forms, realizes that down nib 121 is connected with the engaging of the shaft of a writing brush 11, certain; When needs will descend nib 121 from the shaft of a writing brush 11, to take apart; Then can rotate down nib 121 in the opposite direction, first projection of first snap rings 123 under making in the nib 121 is deviate from from the breach 114 of chute 113, and will descend nib 121 pulling downwards; Thereby, the dismounting of the nib 121 and the shaft of a writing brush 11 under realizing.
Certainly, also can with chute with and the breach that extends to form be arranged on the inwall of first snap rings, and accordingly, can on the shaft of a writing brush engages the outer surface of body, be provided with and first engage the chute of body and first projection that breach cooperatively interacts.
Certainly, following written 121 in above-mentioned be when 11 engagings link together with the shaft of a writing brush, for make connect between the nib 121 and the shaft of a writing brush 11 down firm; Can not break away from snap-fit relationship owing to the vibrations in the external world; Be provided with the protrusion means that can be pressed on first snap rings 123 in the chute 113 of engaging body 111, like this, when first snap rings 123 cooperates with engaging body 111; Because the effect of the bulge-structure 112 in the chute 113; Can increase frictional force between the engaging body 111 and first snap rings 123, thereby, connect firm under also making between the nib 121 and the shaft of a writing brush 11.
In order to realize being fixedly connected of threaded rod 1254 lower ends and following nib 121; The inner surface of following nib 121 is provided with first scrobicular ring; Corresponding; The lower end of threaded rod 1254 then is provided with first bulge loop 12541 that matches with this first scrobicular ring, through the cooperation of this first scrobicular ring and first bulge loop 12541, can realize being fixedly connected of threaded rod 1254 and following nib 121.
When threaded rod 1254 in rotating process; Threaded collar 1251 outside threaded rod 1254 is also rotated along with threaded rod 1254, does not only rotate with the rotation of threaded rod 1254 with threaded collar 1251, just can realize threaded collar 1251 moving on threaded rod 1254; In the present embodiment; The outer surface of threaded collar 1251 is provided with second scrobicular ring 1252, and is embedded with butt circle 124 on second scrobicular ring 1252, and this butt circle 124 can be connected on the inwall of the shaft of a writing brush 11; Like this; Because the frictional force on butt circle 124 and the shaft of a writing brush 11 inwalls, can guarantee that threaded collar 1251 can not rotate along with the rotation of threaded rod 1254, when not hindering this threaded collar 1251 moving up and down along threaded rod 1254.
