Background technology
In accounting education, abacus is required course, and teaching demonstration abacus is very important teachingTeaching aid. In teaching process, often need teacher to make to student of hand-held traditional abacus for teaching demonstrationDemonstration, makes troubles to teaching like this. For this problem, during the patent No. is 201120175578.2State's patent discloses a kind of abacus for teaching demonstration, utilizes two annulus and the connecting line that is connected two annulus,On body of wall, nail, abacus is suspended on body of wall, and be provided with stand abacus can be stood upOn desktop. The weak point of this patent is: it must could hang in conjunction with the nail on body of wall while suspension,Do not need the used time, nail impact is attractive in appearance also dangerous; Although its stand has solved the problem that abacus stands up,But stand is fixedly installed in bottom, can affect suspension; Its bead is fixing not firm, puts in settingThe easy landing of bead while putting.
Summary of the invention
In order to address the above problem, the invention provides abacus for teaching demonstration.
According to an aspect of the present invention, provide abacus for teaching demonstration, it comprises abacus body, abacusBody comprises annular peripheral frame, crossbeam, lever, bead and magnetic stripe dish, and crossbeam is arranged in annular peripheral frame,Lever is arranged in crossbeam, and bead string is at lever, and bead is inlaid with iron sheet, and magnetic stripe dish adopts plastic material,The left and right sides of magnetic stripe dish is provided with buckle, and magnetic stripe dish is installed on the back side of abacus body, magnetic by buckleIn bar dish, be inlaid with magnetic stripe, magnetic stripe and lever are corresponding one by one, and the top of abacus body is provided with suspender,The bottom of abacus body is symmetrically arranged with two folding legs, is provided with folding joint on folding leg. Thus,Bead is inlaid with iron sheet, is inlaid with the magnetic stripe of vertical arrangement in magnetic stripe dish, and magnetic stripe and lever are corresponding one by one,Utilize the fixing principle of magnetic force, abacus in the process of demonstration, while ensureing that bead pushes optional position notMeeting landing, bead is fixed, is difficult for landing; In the time keeping flat demonstration, while not needing to utilize magnetic force to fix,Buckle can be untied, convenient and swift; Folding leg is set, in the time that needs stand up, folding leg is strutted,Two folding legs support abacus body are stood up, and height regulates by the angle that regulates leg, and folding leg isCan be movable, when suspension, do not interfere.
In some embodiments, suspender comprises two vacuum suctions that are symmetricly set on abacus bodies topDish. Thus, adopt vacuum cup as suspender, when suspension, only need to smooth blackboard-cleaning is dryOnly just can hang arbitrarily, without nailing in addition, hang more convenient.
In some embodiments, folding joint comprise joint extension bar one, ratchet, ratchet, trip bolt,Alignment pin, joint extension bar two and ratchet connecting rod, ratchet connecting rod is fixed on joint extension bar one, ratchet settingIn joint extension bar two, alignment pin is arranged on joint extension bar two and acts on ratchet, and ratchet connecting rod arrangesIn ratchet, between ratchet and ratchet connecting rod, be connected with trip bolt.
Advantage of the present invention is: the present invention is simple in structure, scientific and reasonable, utilizes the fixing principle of magnetic force,Abacus is in the process of demonstration, and bead is fixed, is difficult for landing, in the time keeping flat use, can untieThe face left buckle at right two ends of magnetic stripe, convenient and swift; Adopt vacuum cup as suspender, only need to put downWhole blackboard-cleaning totally just can hang arbitrarily, hangs more convenient; Folding leg is strutted to two foldingsFolded leg supports abacus body is stood up, and height regulates by the angle that regulates leg.
