Abstract
The utility model discloses a mechanical type operates exerciser for mathematical education, including the support body, and set up under and the digital generating means in inboard the last digital generating means of support body, go up digital generating means and install arithmetic symbol mechanism down between the digital generating means, power unit installs in the outside in arithmetic symbol mechanism, it includes at least three group's lettered dials with lower digital generating means to go up digital generating means, keep away from power unit one end lettered dial one side is fixed with first gear, remain each lettered dial one side is fixed with a drive plate, each its specification of drive plate is different, lettered dial and drive plate all pass the fixed axle, fixed axle outside side -mounting has the pivot, the utility model discloses a mechanical type operates exerciser for mathematical education can realize that student oneself takes out the topic, and can see the digit and roll that it can bring certain visual impact for the student, arouses student's interest in learning.
Description
Technical field
This utility model relates to a kind of teaching aid, is specifically related to a kind of mathematical education mechanical type calculation exerciser, belongs to teaching technique with the apparatus field。
Background technology
In mathematics, when one-level computing (plus-minus) and two grades of computings (multiplication and division) simultaneously appear in a formula, their order of operation is first multiplication and division, rear plus-minus, if having bracket just first to calculate after in bracket to calculate outside bracket, being from left to right with one-level order of operation, such computing is four arithmetic operation；Before Students ' Learning four arithmetic operation, it is necessary to firmly grasp one-level computing and two grades of computings；In existing one-level computing and two grades of computing teaching processes, teacher often spot-check student's grasp ability to computing, and its learning process is uninteresting, is difficult to cause student interests。
Utility model content
(1) to solve the technical problem that
For solving the problems referred to above, the utility model proposes a kind of mathematical education mechanical type calculation exerciser, it is possible to realize student oneself and take out topic, and it can be seen that numeral rolls, it can bring certain visual impact to student, causes student learning interest。
(2) technical scheme
Mathematical education mechanical type calculation exerciser of the present utility model；Including support body, and be arranged at inside support body on be digitally generated mechanism and under be digitally generated mechanism；Be digitally generated on described mechanism and under be digitally generated between mechanism and operational sign of four fundamental rules mechanism be installed；It is installed to actuating unit outside described operational sign of four fundamental rules mechanism；Be digitally generated on described mechanism and under be digitally generated mechanism and include at least three group lettered dials；Described lettered dial side away from actuating unit one end is fixed with the first gear；Remain each described lettered dial side and be fixed with a drive plate；Its specification of each described drive plate is different；Described lettered dial and drive plate both pass through fixing axle；The outer avris of described fixing axle is provided with rotating shaft；Described rotating shaft is provided with drive plate just to rotating disk, and the second gear engaged with the first gear；Described rotating disk is connected by drive mechanism with drive plate；Described operational sign of four fundamental rules mechanism includes transaxle；Described transaxle is provided with symbol disc；Described transaxle is provided with the 3rd gear away from actuating unit one end；Described first gear and the engagement of the 3rd gear。
Further, described actuating unit is motor。
Further, plus sign, minus sign symbol, multiplication sign symbol and division sign symbol are carved with in described symbol disc interval。
(3) beneficial effect
Compared with prior art, mathematical education mechanical type calculation exerciser of the present utility model, it is possible to realize student oneself and take out topic, and it can be seen that numeral rolls, it can bring certain visual impact to student, causes student learning interest。
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model。
Detailed description of the invention
The mechanical type calculation exerciser of mathematical education as shown in Figure 1, including support body 1, and be arranged at inside support body 1 on be digitally generated mechanism 2 and under be digitally generated mechanism 3；On be digitally generated mechanism 2 and under be digitally generated between mechanism 3 and operational sign of four fundamental rules mechanism 4 be installed；Actuating unit 5 it is installed to outside operational sign of four fundamental rules mechanism 4；On be digitally generated mechanism 2 and under be digitally generated mechanism 3 and include at least three group lettered dials 6；Lettered dial 6 side away from actuating unit 5 one end is fixed with the first gear 7；Remain each lettered dial 6 side and be fixed with a drive plate 8；Its specification of each drive plate 8 is different；Lettered dial 6 and drive plate 8 both pass through fixing axle 9；The fixing outer avris of axle 9 is provided with rotating shaft 10；Rotating shaft 10 is provided with drive plate 8 just to rotating disk 11, and the second gear 12 engaged with the first gear 7；Rotating disk 11 is connected by drive mechanism 13 with drive plate 8；Operational sign of four fundamental rules mechanism 4 includes transaxle 15；Transaxle 15 is provided with symbol disc 16；Transaxle 15 is provided with the 3rd gear 14 away from actuating unit 5 one end；First gear 7 and the 3rd gear 14 engage。
Actuating unit 5 is motor。
Plus sign, minus sign symbol, multiplication sign symbol and division sign symbol are carved with in symbol disc 16 interval。
During use, switch is opened in study, and motor can drive transaxle 15 to rotate, while transaxle 15 rotates switch operation symbol, driving the first gear 7 action by the 3rd gear 14, the first gear 7 drives the second gear 12 action, makes rotating shaft 10 rotate, in rotating shaft 10 rotation process, cause owing to drive plate 8 is diversified in specifications, in its transmission process, make each lettered dial 6 numeral different, its randomness is good, it is possible to fully test student's operational capability。
