Abstract

The utility model relates to a zero clearing counter, which comprises a zero clearing cross bar and a plurality of U-shaped sliding rods which are evenly arranged side by side; each U-shaped slide bar is serially arranged with the zero clearing cross bar after ten abacus beads are serially arranged, each U-shaped slide bar is inserted into the base plate through two ends of the U-shaped slide bar to form a counting frame, and the zero clearing cross bar simultaneously pushes the abacus beads on the counting side of each U-shaped slide bar to reset to form a zero clearing structure. Has the advantages of simple structure and one-time action for completing reset and zero clearing of the abacus beads.

Description

Zero clearing counter

Technical Field

The utility model relates to a zero clearing counter.

Background

For primary mathematics education of children or pupils, the traditional mode is to draw pictures on a blackboard for addition, subtraction and multiplication teaching, the teaching mode is boring and tasteless, students cannot operate by hands, and learning interest is not strong. In order to arouse the interest of students in learning, various counters have been designed, and after counting, if recounting is needed, the counting beads on the counting side of each slide bar are required to be repeatedly pulled to the original position side of the slide bar by a handle.

Disclosure of Invention

The utility model aims at the above problems, and provides a reset counter which has a simple structure and can complete the reset of the abacus beads by one action.

The purpose of the utility model is realized like this: the device comprises a zero clearing cross bar and a plurality of U-shaped slide bars which are uniformly arranged side by side; each U-shaped slide bar is serially arranged with the zero clearing cross bar after ten abacus beads are serially arranged, each U-shaped slide bar is inserted into the base plate through two ends of the U-shaped slide bar to form a counting frame, and the zero clearing cross bar simultaneously pushes the abacus beads on the counting side of each U-shaped slide bar to reset to form a zero clearing structure.

The utility model discloses, the zero clearing whippletree is provided with a hand and holds, makes things convenient for the finger to stir.

The utility model discloses, ten beads that string dress were gone up to same U type slide bar are the beads that calculate of a colour, and the bead colour that string dress was gone up to adjacent U type slide bar is different.

The utility model discloses, U type slide bar is made by pliability material.

The utility model discloses, the zero clearing horizontal bar of cluster dress in each U type slide bar stirs the beads that count on the side to each U type slide bar simultaneously, and the zero clearing is accomplished in an action.

The following examples are further illustrative of the present invention with reference to the accompanying drawings.

Drawings

Fig. 1 is a schematic perspective view of an embodiment of the present invention;

fig. 2 is a schematic perspective view of the embodiment of fig. 1 in a use state.

In the figure, 1, clear bar; 2. a U-shaped slide bar; 3. a seat plate; 4. calculating beads; 5. carrying out hand holding; 6. a clock.

Detailed Description

Referring to fig. 1 to 2, the present embodiment is a zero clearing counter, which includes a zero clearing bar 1 and five U-shaped sliding rods 2 arranged side by side; each U-shaped slide bar is serially arranged with a zero clearing cross bar after ten abacus beads are serially arranged, each U-shaped slide bar is inserted on the base plate 3 through two ends of the U-shaped slide bar to form a counting frame, and the zero clearing cross bar simultaneously pushes the abacus beads 4 on the counting side of each U-shaped slide bar to reset to form a zero clearing structure; the zero clearing cross bar is provided with a handle 5 which is convenient for being stirred by fingers; ten beads which are stringed on the same U-shaped slide bar are beads with one color, and the beads stringed on adjacent U-shaped slide bars are different in color; the U-shaped sliding rod is made of flexible materials.

The utility model discloses, the zero clearing counter can adopt five lines, nine lines, thirteen lines etc.. The seat plate may also be provided with a clock 6.
