Abstract

The utility model is composed of four components such as a pencil sleeve, a connecting sleeve, a curve rotary switch and a pencil vase. The inside of the connecting sleeve and the inside of a pencil vase rod are both provided with three pencil cores with pins and three pencil heads, the three pencils cores with pins slide in a movable slot arranged by the pencil vase rod and the connecting sleeve, and the outer diameter of the connecting sleeve along the outer edge of the movable slot of the pencil cores with pins is provided with the curve rotary switch. The pin positions of the pencil cores with pins run along the track rotated by a curve, namely, a valley value is arranged at the position of 120 DEG on the same circumference, and two peak values are arranged on the positions at intervals of 120 DEG. The utility model integrates the pencil cores with multiple colours into integration, when the utility model is written, the switch can be rotated in universal directions, and the pencil cores can be automatically opened and closed simultaneously.

Description

The Multicolor pencil of automation curve rotary switch

The utility model belongs to cultural goods.

Before the utility model comes out, only monochromatic one of commercially available Multicolor pencil, 12 kinds of colors must be assorted twelve earthly branches, exist the shortcoming that number is many, volume big, easy dispersion is lost.Although I have spent certain time to the architecture advances aspect of a Multicolor pencil, and have obtained patent right.Its patent No.: 93208173.8, title: the Multicolor pencil of twin-lock direction toggle switch integral type.But after the test manufacture trial sale, generally Fan Ying problem is to stir out pen core fashion conveniently in a small amount, and the operation that the withdrawal pen core stops to write owes convenient, therefore not operation, and palpus is done further to improve.

Therefore, the utility model is on above-mentioned basis, changes the automation curve rotary switch into by the structure of twin-lock direction toggle switch.Thereby design a kind ofly can go out pen core and write, can regain the Multicolor pencil that pen core stops to write automatically simultaneously again by rotation.And design with this and to weed out the old and bring forth the new, improve the diversification of polychrome ballpoint pen structure.

For realizing this design, be divided into four parts on its structure, i.e. the pen cap, adapter sleeve, curve rotary switch and pen container.The major technique feature is that the pen container parts are provided with adapter sleeve 6 and pen tube rod 4, and three band pin pen cores 5 and nib 1 all are equipped with in its inside.The slippage in the set loose slot of pen tube rod and adapter sleeve of these three band pin pen cores.Along the outer of band pin pen core loose slot 18 curve rotary switch 7 is housed at the adapter sleeve external diameter.Its operation principle is that the band pin position of band pin pen core 5 is track 16 operations along the curve rotation, and promptly one " valley " established in 120 ° of positions on same circumference, locates to be provided with " peak value " at 120 ° that are separated by.In the track 16 of 360 ° of circumference, be provided with altogether like this one " valley " and two " peak value ", be installed in the loose slot and be with the pin pen core to be with spring 9, because the elastic reaction of spring, force three band pin pen cores when doing the curve rotation, wherein must there be a band pin pen core to be threaded to " valley ", so nib promptly is sent penholder, in addition two then are in " peak value " and locate locked.When not being rotates to " valley " and " peak value " when locating, be with the pin pen cores all to belong to blocking for these three.

The utility model integrates the polychrome pen core, and switch can universal rotation when writing, and pen core can be finished Kai Heguan simultaneously automatically, and compact conformation, outward appearance novelty, volume little, be easy to carry, certain application value is arranged.

Now in conjunction with the accompanying drawings its structure is described below:

Fig. 1 is a structure chart of the present utility model, made half section among the figure, pen tube rod 4 is to adopt Bolt Connection with adapter sleeve 6, three band pin pen cores 5 are distributed in the loose slot 18, in each band pin pen core, colored fiber core 3 is housed, its knockout end has all clamped nib 1, and compression spring 9 is contained in the band pin pen core, is placed in the spring base 11 of middle pen container 10.External diameter at adapter sleeve 6 is overlapping curve rotary switch 7.The order of installing is to put the compression spring on three little chock plug 8 pillars in band pin pen core back top separately that will assemble, in the spring base 11 of packing into simultaneously.The pen cap 2 outside being with outside pen tube rod, are provided with rotary label 12 on the curve rotary switch, and to color marker 13, are provided with colour code 14 on pen tube rod, also pen clip 15 can be housed on the pen cap outside, also made A-A among the figure and analysed and observe.

Fig. 2 is the A-A cutaway view, shown in colored fiber core 3, band pin pen core 5, pen tube rod 4 is provided with A-frame 17 in adapter sleeve, loose slot 18 is provided with snap close 19 on the top of band pin pen core.

Fig. 3 is the cutaway view of band pin pen core 5, shown in nib 1, the location drawing of snap close 19; Fig. 4 is a band pin pen core vertical view; The right view of Fig. 5 band pin pen core; Fig. 6 is band pin pen core upward view, wherein looked band sell two sides of pen core be 120 ° fan-shaped.

Fig. 7 is the outline drawing of curve rotary switch, has wherein also made partial view B.Fig. 8 is a left view, and Fig. 9 is a right view, Figure 10 be the local B that amplifies to view, it is 20 ° of direction positioning ports, Figure 11 is the internal diameter expanded view of curve rotary switch.

Operator when writing promptly locatees automatically as long as the curve rotary switch is arbitrarily rotated 120 ° by check colors a sign left side or right, and a kind of color pen core stretches out the pen container mouth, can write, and can locate automatically when rotating 60 ° again, promptly is in blocking.This Multicolor pencil can singly prop up the structure manufacturing, also can adopt single bipitch structure manufacturing, also can be with the manufacturing of this structure applications in the polychrome ballpoint pen.

Claims

1, the Multicolor pencil of automation curve rotary switch is made up of the pen cap, adapter sleeve, curve rotary switch and pen container four parts.It is characterized in that the pen container parts are provided with adapter sleeve 6 and pen tube rod 4, three band pin pen cores 5 and nib 1 all are equipped with in its inside, the slippage in the set loose slot of pen tube rod and adapter sleeve of these three band pin pen cores is equipped with curve rotary switch 7 at the adapter sleeve external diameter along the outer that band is sold pen core loose slot 18; The band pin position of band pin pen core 5 is track 16 operations along the curve rotation, promptly " valley " established in 120 ° of positions on same circumference, locate to be provided with two " peak values " at 120 ° that are separated by, band pin pen core is with spring 9 and is installed in the loose slot, during the curve rotation, wherein must have a band pin pen core to be threaded to " valley ", two then are in " peak value " in addition, when not being rotates to " valley " to locate with " peak value ", be with the pin pen cores all to belong to blocking for these three.
