Abstract
The utility model relates to a dual-purpose bead mental arithmetic abacus, which comprises an abacus consisting of a frame, bridges, shelves and beads and an abacus board fixed on the back of the abacus. The frames, bridges and shelves which are printed on the abacus board can be used for not only counting by the beads but also by mental arithmetic, which solves the disadvantages that the prior abacus with beads is not convenient to calculate without beads and that an abacus without beads is not convenient to calculate with beads.
Description
Technical field:
The utility model relates to the rechoning by the abacus utensil.
Background technology:
Abacus is the traditional computational tool of China, and it is made up of shelves and the pearl of string on shelves that frame all around, middle beam link to each other with frame, beam, utilizes the computing method of abacus to be called rechoning by the abacus.The process of rechoning by the abacus can be calculated by row that the reality of bead is dragged on, also can be by imitative the dialling (empty dialling) and the capable mental arithmetic of wanting to drag on.Present imitative dialling is to have only frame, beam, shelves and do not have and carry out on the special-purpose abacus of mental arithmetic of pearl a kind of, make real dial with imitative group can not carry out with same abacus, make troubles to the user.
Summary of the invention:
The purpose of this utility model provides a kind of can dial in fact and can the empty dual-purpose abacus mental calculation abacus of dialling.By increasing an abacus plate that is shaped on frame, beam, shelves behind, solve the problems that present rechoning by the abacus, mental arithmetic need two cover instruments at the existing real abacus of dialling.Can satisfy the requirement of rechoning by the abacus and mental arithmetic like this with an abacus simultaneously, bring convenience to the user.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is an abacus plate structure synoptic diagram.
1 is frame among the figure, and 2 is bead, and 3 is the abacus plate, and 4 is the frame on the abacus plate, and 5 is the beam on the abacus plate, and 6 is the shelves on the abacus plate.
Embodiment:
As shown in Figure 1, one side of the present utility model is used abacus, form by frame 1, beam, shelves and bead 2, the back side at this abacus, an abacus plate 3 is as shown in Figure 2 arranged, the frame 1 of it and abacus is fixed with one, and is printed with the frame corresponding with abacus 4, beam 5, shelves 6 on the abacus plate, and anchor point is arranged on the beam.Can imitate on abacus plate 3 corresponding shelves during mental arithmetic and dial, the another side of this abacus can carry out reality and dial rechoning by the abacus.
Claims (2)
1. dual-purpose abacus mental calculation abacus, it is made up of frame (1), beam, shelves and the bead (2) of string on shelves, it is characterized in that the back side of this abacus also has an abacus plate (3) that is shaped on frame (4), beam (5), grade (6).
