Detailed Description

In order to clarify the technical solution and working principle of the present invention, the present invention is further described in detail with reference to the following embodiments in conjunction with the accompanying drawings, it should be noted that, without conflict, the embodiments or technical features described below may be combined to form a new embodiment.

Example one

The invention provides an arithmetic training teaching aid as shown in figures 1-2, which comprises a base 10 and a demonstration board 20 arranged on the base 10.

A pair of supports 11 is fixedly mounted on the base 10, the supports 11 are vertically arranged, a plurality of mounting holes 12 are formed in the supports 11, supporting rods 21 are arranged on two sides, close to the supports 11, of the demonstration board 20, positioning pins 13 are inserted into the mounting holes 111 in a penetrating mode, the demonstration board 20 moves up and down, and positioning is carried out through the different mounting holes 12. Demonstration board 20 that can height-adjusting satisfies the needs of not co-altitude children's operation, and the practicality is strong.

The rotation wheel 30 is installed to base 10 lower extreme, be provided with fixed block 40 on the base 10 in the support 11 outside, be provided with balancing weight 50 on the base 10, constant head tank 41 has been seted up on the fixed block 40, balancing weight 50 upper end is fixed with L type connecting rod 60, L type connecting rod 60 upwards passes base 10 to be connected with constant head tank 41 block on the fixed block 40. When the base 10 needs to be moved, the L-shaped connecting rod 60 is pulled to lift the counterweight block 50 upwards, so that one end of the L-shaped connecting rod 60 is clamped with the positioning groove 41 on the fixing block 40; when needs fixed baseplate 10, pulling L type connecting rod 60 upwards promotes balancing weight 50, makes L type connecting rod 60 one end and the constant head tank 41 classification on the fixed block 40 to L type connecting rod 60 rotates, makes L type connecting rod 60 originally keep away from fixed block 40 with the one end of the constant head tank 41 contact on the fixed block 40, then balancing weight 50 is fixed subaerial under the action of gravity.

A plurality of recesses 22 have been seted up to the terminal surface before demonstration board 20, demonstration board 20 is inside to be rotated and to be provided with the different character block group 80 of multiunit digit block group 70 and multiunit, every group digit block group 70 or character block group all set up the outer lane at disc 90, disc 90 sets up inside demonstration board 20, disc 90 middle alternate has pivot 100, pivot 100 is connected with demonstration board 20 bearing, demonstration board 20 is worn out and is connected with rotatory handle 110 to the one end that disc 90 was kept away from to pivot 100, drives disc 90 through rotating rotatory handle 110 and rotates for recess 22 department is aimed at to digit block or character block on the disc 90, the size of digit block and character block is all not greater than recess 22's size. The number block set 70 includes zero to nine, the character block set 80 includes an arithmetic character block including "+", "-", "×", "+", and a comparison character block including "═", "<", ">". The rotatable disc 90 aligns different number blocks or character blocks of each group of number block or character block groups to the groove 22 to form different combinations of arithmetic for children to train, and the arithmetic type combinations are of various types, so that children at multiple ages can learn the arithmetic.

The magnifier 120 is arranged on one side of the front end face of the groove 22, so that the digital block or the character block can be magnified to present a larger font, and the recognition is easier.

Example two

The present embodiment is the same as the first embodiment, so the same parts are not repeated, and the difference between the present embodiment and the first embodiment is that each group of the number blocks 70 or the character blocks 80 is circumferentially distributed and is fixedly connected to the rotating shaft 100 through the connecting rod 130, one end of the rotating shaft 100 far away from the connecting rod 130 penetrates through the demonstration board 20 and is connected to the rotating handle 110, and the rotating handle 110 is rotated to drive the number blocks 70 or the character blocks 80 to rotate, so that different number blocks or character blocks are aligned to the grooves 21.

The working principle of the invention is as follows:

first, the L-shaped connecting rod is separated from the fixing block, so that the balancing weight is fixed on the ground under the action of gravity, and then different arithmetic training subjects are combined for training by adjusting the rotating handle.

The specific training process is as follows: instructional value dictation arithmetic questions: three times five equals how much, then operating the rotary knob 110 adjusts the number block group and the character block and calculates the structure, rendering "3 × 5 ═ 15" through the magnifying glass.

The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may be made by those skilled in the art without departing from the principle of the invention.
