Problems solved by technology

Sexagesimal has not been found in various address codes in the current digital equipment and communication fields.
[0011] However, the inventors have learned that although the existing decimal coded elements and the corresponding improved decimal coded elements can provide greater coding capacity, because the number of elements is ten times that of the existing decimal coded elements, resulting in its There are great difficulties in quick search, identification and learning, and it is not easy to promote
Simple printing of decimal elements on paper is inconvenient for long-term storage, takes up a large area when used, and is not convenient for comparative learning of decimal elements and decimal elements

Embodiment 1

[0080]Such asFigure 1-Figure 8 As shown, this embodiment provides a hundred element learning sliding ruler, which includes a base 1 in which a plurality of parallel sliding grooves 12 are arranged in a row. The sliding grooves 12 are provided with sliding plates, and the sliding plates are marked with A hundred elements, a plurality of sliding pieces can independently stretch along the sliding groove 12, so that different sliding pieces are exposed outside the base body 1.

[0081]The slide has a decimal printing area 7 and a hundred printing area 8, and the number of indications of the hundred elements in different slides is the same.

[0082]The surface of the substrate 1 forms a marking surface, and the marking surface and the sliding sheet jointly mark the hundred elements. The marking surface and each sliding sheet are marked with 20 hundred elements, and the number of the sliding sheets is four.

[0083]It can be understood that, in this embodiment, the number of buttons is also four, ...

Embodiment 2

[0093]Such asFigure 9-12As shown, a learning sliding ruler with hundreds of elements is also provided. The difference between this embodiment and Embodiment 1 is that the sliding plate includes two half sliding plates, and the two half sliding plates are spliced ​​to form a sliding plate. The end of the sliding piece is provided with a half-protruding piece. The two sliding pieces are respectively used to indicate the decimal element and the corresponding decimal element value. The two half-protruding pieces are spliced ​​to form a convex piece; Slide and position in the width direction of the sheet, so that the buttons are respectively aligned with the two half-protruding sheets used in conjunction with each other, so that the two half-sliding sheets can expand and contract independently.

[0094]There are two upper buckles 10 in each chute 12, and one lower buckle 9 is respectively provided on each half-protruding piece.

[0095]Specifically, the drawings of the specification exemplaril...

Abstract

The invention relates to a hundred-system element learning sliding ruler which comprises a base body, a plurality of parallel sliding grooves are formed in the base body in columns, sliding pieces arearranged in the sliding grooves, hundred-system elements are marked on the sliding pieces, and the multiple sliding pieces can independently stretch out and draw back along the sliding grooves so that different sliding pieces can be exposed out of the base body. According to the invention, the learning of the hundred-system elements can be realized conveniently.

Description

Technical field[0001]The present disclosure belongs to the technical field of learning teaching aids, and in particular relates to a learning sliding ruler with hundred elements.Background technique[0002]The statements here only provide background art related to the present disclosure, and do not necessarily constitute prior art.[0003]Binary 0, 1 is represented by high level ---1 and low level ---0 in digital circuits, digital devices and computers. Easy to handle in computers and digital devices. Promote the development of binary coding and the progress of modern science and technology.[0004]Decimal counting was invented by Hindus 1500 years ago and passed down to the 11th century by Arabs. Various address codes are used most, such as mobile phone numbers, which use decimal addressing coding mode. The basic elements of decimal coding: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 every decimal (full decimal one), philosopher’s explanation: people have ten fingers, put this finger Head count. So dec...
