Description

Mathematical operation cylinder

Technical field

The utility model relates to field of stationery.Be specifically related to mathematical operation cylinder.

Background technology

The instrument that traditional mathematics calculates is abacus and counter, and abacus and counter have certain difficulty for child, need could grasp through special training, and these two kinds of instruments are interesting not enough, and child is usually not interested in use.

CN200810122600.X discloses the instrument that a kind of child of allowing passes through to learn with rolling magic cylinder interest basic algorithm calculations.It is made up of the first rotating disk, the second rotating disk, the 3rd rotating disk, the 4th rotating disk, the 5th rotating disk, the 6th rotating disk, central shaft, demonstration frame, numeral and compute sign, first rotating disk, the second rotating disk, the 3rd rotating disk, the 4th rotating disk, the 5th rotating disk, the 6th rotating disk are gone here and there on center shaft in turn, demonstration frame is in the periphery of each rotating disk, on center shaft, numeral and compute sign are imprinted on each rotating disk in two riveting.

This device passes through six rotating disks arranged in parallel, define a kind of interesting roll operations cylinder preferably, but it still exists following shortcoming:

This device needs child oneself to carry out computing to each state, after obtaining a result, then answer is rolled to corresponding position, and this not all child can accurately complete, and the child for just contact arithmetical operation is very difficult.

Computing cylinder is divided into multiple rotating disk, and each rotating disk does corresponding rotation, and after long-time, situation about fluffing may appear in inner core and urceolus contact position, affects location and the relative position of each rotating disk, and rotation can reduce the serviceable life of computing cylinder for a long time.

Utility model content

It is simple that the purpose of this utility model is to provide a kind of structure, operates easy, interesting strong mathematical operation cylinder.

In order to achieve the above object, the utility model has following technical scheme:

Mathematical operation cylinder of the present utility model, comprises inner core, urceolus, and inner core coaxial sleeve is located in urceolus, and inner core and urceolus can relatively rotate, and is circumferentially with the computing board indicating 0-9 numeral of order discharge on the left of described inner core; The right side of computing board is circumferentially with operational symbol number plate; The result board corresponding with computing board is circumferentially with on the right side of inner core; Be circumferentially with on the left of described urceolus order discharge indicate 0-9 numeral by computing board; The number plate such as to be provided with on the right side of computing board; Described by the left side of computing board, etc. be respectively equipped with operational symbol number plate window corresponding to AND operator number plate, result board and result board window on the right side of number plate.

Further, described operational symbol number plate is for adding number plate or multiplication sign board.

Further, inner core is axially arranging the first limit body coordinated with urceolus, and the number plate that adds that the first limit body controls inner core coordinates with the sign of operation position window of urceolus.

Further, inner core is axially arranging the second limit body coordinated with urceolus, and the second limit body controls the multiplication sign board of inner core and coordinates with the sign of operation position window of urceolus.

Further, the odd number of described result board circumference is classified as the result board of computing addition, and the even number of result board circumference is classified as the result board of computing multiplication.

Owing to taking above technical scheme, the utility model has the advantage of:

1, the utility model is simple and reasonable, simple to operate, often rotates and once only occurs a computing equation;

2, computing cylinder can by rotating calculation operations result, and improve the learning interest of arithmetic beginner, long-time rotation also can not affect serviceable life.

Embodiment

Below implement for illustration of the utility model, but be not used for limiting scope of the present utility model.

See Fig. 1-4, the present invention is mathematical operation cylinder of the present invention, comprises inner core, urceolus, and inner core coaxial sleeve is located in urceolus, and inner core and urceolus can relatively rotate, clearance fit, is circumferentially with the computing board indicating 0-9 numeral of order discharge on the left of inner core; The right side of computing board is circumferentially with operational symbol number plate, and operational symbol number plate is for adding number plate or multiplication sign board; The result board corresponding with computing board is circumferentially with on the right side of inner core, the odd number of result board circumference is classified as the result board of computing addition, between the row of the odd column of the result board circumference corresponding with 0-9 computing board and line number value, arrange be arithmetic progression between columns value, the even number of result board circumference is classified as the result board of computing multiplication, row and the columns value of the even column of the result board circumference corresponding with 0-9 computing board are Geometric Sequence, and between row and row, numerical value is arithmetic progression.

As Fig. 5-6, preferably, in order to the accurate location of inside and outside cylinder numeral, operational symbol, equal sign and result, inner core is axially arranging the first limit body coordinated with urceolus, and the number plate that adds that the first limit body controls inner core coordinates with the sign of operation position window of urceolus.
