Description

Pen with abacus

The utility model is a kind of lettering pen of double band abacus computation device.

Abacus is as the traditional operational tool of China, owing to have intuitive and iconicity, can reflect the thought process of computing, even if thereby in today of electronic computer technology high development, it still has unique effect.Along with the reform and development of structure of education, primary grades has also been offered the rechoning by the abacus course in recent years, and it also is being a kind of effective means aspect the knowledge and skills of cultivating number of students.But because the restriction of the structure of abacus removes under the specific study and work occasion, people go out to carry inconvenience more.People need carry out some simple computation sometimes when writing equally in daily life, only depend on one-pen also can not meet the demands well.In addition,, still there is how to excite them to learn the interest of rechoning by the abacus the condition question that the creation time after school learns at any time for the pupil.

For addressing the above problem, the utility model provides a kind of lettering pen of double band abacus computation device, it utilizes Shooting Technique at peripheral 4～6 gears fluting abacus that increases a near-ring shape of the cap for brush, the effect of abacus and pen is combined into one, simple structure (only being that a shell is slightly thicker than existing lettering pen), cost increases little, is convenient for people to carry also to play decoration function.

Below with reference to accompanying drawing the utility model is narrated.

Fig. 1 is the side view of Pen with abacus.

Fig. 2 is this cutaway view along the A-A line.

Fig. 3 is this cutaway view along the B-B line.

Fig. 4 is the vertical sectional drawing of a side of the cap for brush.

Fig. 5 is the outline drawing of dialling pearl as Glochidion puberum.

With reference to accompanying drawing, this Pen with abacus by a body (1) with mould the cap for brush (2) two parts firmly and form, be about the card of the arc surface at 4/3 π angle with the cap for brush (2) periphery as abacus, other spatial domain of cap for brush periphery is used to be provided with pen clip (9).As the arc distances such as top of the arc surface of abacus card have a upper groove (3) that 4～6 road cross sections are isosceles trapezoid, on the extend longitudinally line of the upper groove of per pass (3) bottom, have the next groove (4) of same cross section, the next groove (4) is longer than upper groove more than (3) one times, the crossbeam (5) of part as abacus that do not communicate between two grooves.

The colour that the utility model adopts soft-plastic material to make pulls out the bead on the alternative abacus of pearl (6), as shown in Figure 5.The positive side cross section that pulls out pearl (6) also is isosceles trapezoid, can combine more closely with each the upper and lower groove on the cap for brush, the upper surface that pulls out pearl (6) is rectangular shape or square shape, at two upside edge chamferings, makes the place of pushing up that connects between the pearl pearl present a leg-of-mutton chase.

During making, the soft colour of moulding is pulled out in pearl (6) the embedding dovetail groove.Can pearl regulation by the tradition of abacus, i.e. interior setting-in two pearls of the upper groove of per pass (3), interior setting-in five pearls of the next groove of per pass (4) are to adapt to the object of begining to learn rechoning by the abacus.Also can take the embedding method of five pearls under four pearls under the pearl or the last pearl, be convenient to common people and use.Be provided with baffle ring (78) is convenient to bead loading and prevents to pull out pearl come off at the upper and the next notch place at cap for brush two ends.Because of having made chamfered on the seamed edge that pulls out pearl (6), the user can promote pearl with the thumbnail of holding a hand and vertically move in groove again, also available carry as key, the small articles of coin one class is stirred and is calculated.

The cap for brush (2) is gone up the color of the abacus part except that pulling out pearl (6) and baffle ring (7,8) with the coordination of these form and aspect of handwriting, with gear pearl color unanimity, the collocation of colour of different gear beads can be flexible, with the whole decorative effect of increase.
