Abstract

The utility model relates to a novel abacus. The utility model is characterized in that noncircular abacus beads are used to thin an abacus; an abacus body can be folded through a hinge arranged on the abacus body, which is convenient for carrying; a clearing button is arranged in a frame to make the use of the abacus be safe; the abacus is especially suitable to be used by pupils who learn the operation of an abacus.

Description

Abacus
The utility model relates to a kind of novel abacus.
Abacus learning is beneficial to intelligence development, and rechoning by the abacus has become an important course of primary school's numeral.But now the student uses abacus ubiquity heaviness, and inconvenience is carried, and the dangerous problem such as fragile of liquidation device even the abacus of one or two kinds of miniaturizations is arranged, uses the part size to be cost to dwindle rechoning by the abacus, though the result is that the realization miniaturization is impracticable.
The purpose of this utility model is to avoid above-mentioned shortcomings and deficiencies, and a kind of slim Foldable abacus is provided.
The purpose of this utility model is achieved in that abacus branch left-right symmetric two parts.Left and right housing (1) (2) three parts has edge, at no edge end, be provided with long frame edge (19) upper limb and lateral margin intersection point is hinge rotating shaft (3) pan (4) in axle center, be connected through the hinge, left and right sides housing is collapsible, the short edge of housing (18) is provided with buckle structure (5), but the left and right sides housing after fastening folds.Folding back hinge side expose portion is covered with thin cover plate (6), with the complete sense after keeping abacus folding.Cover plate (6) is connected with a side body bottom edge (20) with flexible material, and when launching abacus, cover plate (6) stretches into opposite side housing base plate bottom, does not influence abacus and uses.
Liquidation device (7) is housed in the housing, liquidation device bull stick (8) medial side goes out a galianconism (9), kinematic link (11) other end that is connected with liquidation device liquidation knob (10) flexibly connects by rotating shaft and galianconism (9), press liquidation knob (10) by kinematic link (11), act on galianconism (9), produce torque, bull stick (8) is rotated, finish the liquidation action.Liquidation device knob side is installed a back-moving spring (12) and is finished liquidation device homing action.
The whole frid (13) of many notches is equipped with in liquidation device (7) top, and the thin plate of every notch both sides (14) plays the guide rail effect, replaces traditional abacus pin.Non-circular rechoning by the abacus (15) is gone up at guide rail (14) by its underpart guide groove (16) and is slided, and finishes the sub-computing action of rechoning by the abacus, and the sub-top of rechoning by the abacus can be made into rhombus for ease of using.
Novel abacus is compared with traditional abacus, and the advantage of institute's tool is: first point, novel abacus is easy to carry.Abacus slimming in the past must cause rechoning by the abacus to dwindle, bad use.Analysis conventional abacus bead operator structure, finger is by touching just wherein small part, novel abacus bead operator has reasonably removed out the no major part of traditional rechoning by the abacus just, reaches not dwindle rechoning by the abacus use part size and make the abacus slimming, and the folding back of abacus bilayer also has only traditional abacus thick.Second point, it is dangerous to have solved the device of abacus liquidation in the past, flimsy problem.Outside the outstanding abacus frame of tradition abacus liquidation device knob, the knob edge is comparatively sharp keen, occurs drawing, frustrating phenomenon when the pupil uses unavoidably, and the result causes the student to injure.Book also easy to hang, school bag etc. when carrying equally.And novel abacus liquidation knob is installed in the abacus frame, and the outer no any protrusion of abacus housing, event are safely, no
Figure 932333834_IMG2
Thing, not fragile yet.Thirdly, novel abacus manufacturing is installed comparatively simple, can reduce production costs.As but the frid single injection-molded of rechoning by the abacus is installed, avoid traditional abacus that the trouble of pin need be installed by root.The 4th point, novel abacus adopts box structure, can be decorated processing on the box plate, makes it both artistic and practical, avoids the dullness of traditional abacus.
Accompanying drawing one launches vertical view for abacus, and accompanying drawing two is abacus side view and partial sectional view, and accompanying drawing three is sub-side-looking of rechoning by the abacus and cut-open view, and accompanying drawing four is the folding synoptic diagram of abacus, and accompanying drawing five is liquidation device planimetric map.
Below in conjunction with accompanying drawing the utility model most preferred embodiment is described: make left and right sides housing (1) (2), non-circular rechoning by the abacus (15), frid (13), liquidation device knob (10) with plastic injection-moulded method, with sheet metal manufacturing liquidation device (7).Install earlier liquidation device (7) in housing, a back-moving spring (12) is installed in liquidation device knob side.Non-circular rechoning by the abacus (15) is inserted in frid (13) notch with its underpart guide groove (16) position, rechoning by the abacus is gone up at frid (13) upper rail (14) by its guide groove (16) to slide, by a decorative pearl on top of an official cap, four end pearls install rechoning by the abacus (the sub-top of rechoning by the abacus can be made into rhombus).With frid be installed in the shell, on the liquidation device (7), and fixing.Hold the connecting rod (11) that finds the liquidation device at frid (13), crossbeam (17) by short edge (18), the device knob (10) of will liquidating is inserted into its installation position, then with the slightly heating of left and right housing (1), (2) hinge position.Make hinge rotating shaft (3) enter pan (4), folding left and right housing, and, use flexible material (as adhesive tape) that cover plate (6) is connected to a side body bottom edge at last with buckle (5) fastening, it can be rotated freely.Surface of shell can be used pattern decoration.
Launch abacus during use, carry out computing, press liquidation device knob (10) and promptly liquidate.
