Description

The rechoning by the abacus apparatus for demonstrating

(1) technical field:

The utility model relates to a kind of rechoning by the abacus apparatus for demonstrating that usefulness is demonstrated in exhibition center, science and technology center that can be used for.

(2) background technology:

Abacus is to be developed gradually and come by calculating of just generally using as far back as the The Spring and Autumn Period, and is the important invention of Ancient Times in China.At present a lot of exhibition centers, science and technology center adopt the magnetoelectricity controlling schemes in order to represent the calculating process of demonstrating rechoning by the abacus to the visitor, promptly reach the purpose that bead moves up and down by switching electricity and the polarity of controlling each bead, to finish its demo function.But this scheme remains in a lot of immature parts, the one, and magnetic force size, scope control ratio be difficulty, and bead operation is not steady, and it is bigger to implement technical difficulty; The 2nd, adopt wired control mode, very complicated and extremely difficult maintenance of total system circuit.

(3) summary of the invention:

The purpose of this utility model just provides a kind of bead and operates steadily, and is easy to operate, and circuit is simplified, the rechoning by the abacus apparatus for demonstrating that is easy to safeguard.

Rechoning by the abacus apparatus for demonstrating of the present utility model, comprise the calculation frame, bead, the pearl axle that constitute abacus, also comprise wireless transmitting system and computer control system, it is characterized in that: on every grade of pearl axle, tooth bar is housed all, motor and motor-driven thus gear all are housed in each bead, and this gear is meshed with tooth bar on the described pearl axle; Also be embedded with slip on the pearl axle of tooth bar both sides, this slip is connected with power lead respectively and constitutes the loop; Also be equipped with in bead and the corresponding wireless receiving control device of wireless transmitting system, this device is connected with motor and controls its action; On described slip, be slidingly connected oriented motor and wireless receiving control device the power supply the power taking sheet.

One angle sheave detent mechanism also is housed in the described bead.

The utility model independently moves the unit with each bead as one, on the pearl axle of each grade tooth bar is housed all, and the minitype motor driving gear by band brake moves up and down at tooth bar, thereby finishes moving up and down of bead.Adding an angle sheave detent mechanism simultaneously makes the bead operation more steady.Total system comprises 13 grade of 91 pearl, and every grade of bead all can power and operation up and down each bead by a slip electricity getting device power taking.

The utility model adopts ripe wireless signal transmission techniques, each bead all contains and overlaps independently control system and radio receiver and distribute unique identification id number, lay wireless transmitting system in huge abacus bottom, computer control system is installed continuous by USB interface therewith, instruction is also sent in control, and the instruction that bead sends by ID identification receiving computer control system is also sent the operation up and down that bead is finished in the corresponding action instruction by the radio receiver that is connected with micromachine.

The utility model compared with prior art has following characteristics:

(1) this device adopts huge suspension simulation abacus, behind the touch-screen input formula, after the computer control system computational analysis action command wireless transmission is transmitted into each bead, bead carries out corresponding actions after receiving instruction, reach the purpose of simulation shows, embodied U.S. that modern science and technology combines with ancient invention, both had good demonstration effect, have sight again, teach through lively activities.

(2) ripe control, communication, the transmission of utilization, technology and the interior special structures of bead such as conduction have improved the stability and the reliability of operation.

(3) adopt wireless telecommunications control and slip power supply mode, no numerous and diverse circuit is installed and is laid, and wiring is simplified, and is simple to operate, easy to maintenance.

Among the figure: 1-calculates frame, 2-bead, 3-pearl axle, 4-wireless transmitting system, 5-computer control system, the 6-power lead, the little fixed mount of 7-, 8-tooth bar, 9-motor, 10-gear, the 11-slip, 12-power taking sheet, 13-angle sheave wheel shaft, 14-angle sheave, 15-wireless receiving control device.

(5) embodiment:

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, rechoning by the abacus apparatus for demonstrating of the present utility model comprises the calculation frame 1 that constitutes huge abacus, bead 2, and pearl axle 3 is calculated the long 3m of frame, and high 1.44m establishes 13 grade of 91 pearl altogether, every grade of spacing 215mm; The general suspension shows that be provided with wireless transmitting system 4 and computer control system 5 below this abacus, the two connects with USB interface.The bottom calculates to introduce in the frame 24V power lead 6, be provided with a little fixed mount 7 in each bead in the utility model, referring to Fig. 4, the center of this fixed mount is exactly the position of pearl axle 3, the relative pearl axle of fixed mount can move up and down, and each pearl axle rear side all is fixed with a tooth bar 8 from top to bottom, and micromachine 9 and motor-driven thus gear 10 are housed on the homonymy fixed mount, this gear and 8 engagements of described tooth bar move up and down thereby this gear of driven by motor moves the drive bead up and down along tooth bar 8; Respectively embed a slip 11 on the pearl axle of tooth bar both sides, slip joins with aforementioned 24V power positive cathode respectively and constitutes the loop, slidely connects power taking sheet 12 on slip, and this power taking sheet moves up and down on slip and moves up and down with motor.For improving the stability that bead moves up and down, one angle sheave detent mechanism also is housed on the little fixed mount of tooth bar dorsal part pearl next to axis, the two ends of this angle sheave wheel shaft 13 are fixed on the little fixed mount, angle sheave 14 is close to the pearl axle, this detent mechanism also moves up and down with bead, be not offset with assurance pearl axle axle center, thereby bead is operated steadily up and down.In bead, also be equipped with and the corresponding wireless receiving control device 15 of aforementioned wireless transmitting system, signal and instruction that this receiving control device reception external wireless emitter sends are finished actions such as rotating by motor that it connects control, referring to Fig. 5, described motor and this wireless receiving control device be all by power taking sheet 12 power taking from the slip, is connected with lead between motor and wireless receiving control device and the power taking sheet.
