Abstract
The utility model relates to a kind of application machine principle demonstration and autonomous Design is assembled in the teaching aid demonstration instrument of one, specifically be made up of a few parts such as slide way mechanism, clamp mechanism, driving mechanism and support bars, the utility model has powerful, easy to use, structure is simple, and the advantage such as take up room little.
Description
technical field:
The utility model relates to a kind of teaching aid field, and particularly teaching aid shown by the autonomous assembled Practice based machinery of one.
background technology:
Along with educational undertaking keeps reforming and development, classroom level improves constantly thereupon, teaching aid also constantly updates the replacement, traditional mechanical teaching aid function singleness, and a kind of teaching aid can only realize one or both contents of courses, volume is larger, not portable, part dispersion is single, is unfavorable for that student operates in person, can not meet the demand of the education sector of high speed development, the utility model provides a kind of autonomous assembled Practice based machinery to show that teaching aid solves problems.
utility model content:
The utility model object is to provide a kind of autonomous assembled Practice based machinery exposition and practice part combined to show teaching aid, the demonstration of teaching aid function is realized by slide way mechanism, clamp mechanism, driving mechanism and support bar, solve traditional mechanical teaching aid function singleness, volume is larger, not portable, part dispersion is single, is unfavorable for the problems such as student operates in person.
The utility model is based on the mechanical teaching aid of tradition, the structures such as gear engagement mechanism, cam structure, Geneva mechanism, ratchet device and eccentric mechanism are fixed on Box Cover, practice part utilizes fixture and support bar to combine, and realizes the assembled flexibly of often kind of mechanism element and dismounting.
The utility model utilizes outer case and internal box structure as carrying, realized connection and the conversion of casing by chute bar linkage structure, realizes by belt wheel mechanism the Power output showing mechanism.
Practice part of the present utility model is made up of four parts such as slide way mechanism, clamp mechanism, driving mechanism and support bars, distance between slide way mechanism adjustment support bar, be convenient to the cooperation of mechanism, clamp mechanism realizes quick-replaceable and the increase and decrease of part, reach the quick-assembling of mechanical mechanism, driving mechanism provides power for part movement, and connected by transmission shaft and drive, support bar is the motion of part and fixedly providing support of clamp mechanism.
The beneficial effects of the utility model are: powerful, easy to use, and structure is simple, takes up room little.
