Abstract
The utility model discloses a kind of education experiment simple lever Libra.One end of the trapezoidal base of Libra is provided with connected vertical rod, the upper end of vertical rod is provided with connected cross bar, connected arc-shaped weight scaleplate is provided with between cross bar and base, the side of vertical rod is provided with hopper, the lower end of its hopper is provided with support bar, and vertical rod is connected respectively by web joint and weight pointer with support bar.The utility model moulding is unique, and structure is simple, reasonable in design, and application is convenient.The manufacture technology field of school supply and stationery can be widely used in.
Description
Technical field:
The utility model relates to school supply and stationery technical field, is exactly a kind of simple lever Libra used in education experiment.
Background technology:
In present physics or chemistry teaching, because various needs does a large amount of physics or chemical experiment repeatedly.And do these physics or chemical experiment many times all can use Libra.And present Libra great majority are all balance type structures, structure is single, and Reusability can affect students to a great extent and do the temperament and interest of testing.
Summary of the invention:
The purpose of this utility model is for conventional teaching experiment Libra Problems existing, and provides a kind of novel education experiment simple lever Libra.Be utilize lever principle to make can carry out the experiment of lever used for physics theory teaching, can be used as again the simple lever Libra that chemical agent weighs.Its moulding is unique, and structure is simple, reasonable in design, and application is convenient.
For realizing above-mentioned technical purpose, the technical scheme that the utility model is taked is: a kind of education experiment simple lever Libra, comprise base, vertical rod, cross bar, scaleplate, hopper and weight pointer, it is characterized in that: described base is trapezoidal metal pedestal, be provided with the board-like vertical rod be fixedly connected with it in one end of base, the upper end of its vertical rod is provided with the cross bar be fixedly connected with it; Described base becomes parallel shape with cross bar; Described cross bar be provided with the arc-shaped weight scaleplate be fixedly connected with it between base; The side of described vertical rod is provided with hopper, and the lower end of its hopper is provided with support bar, and the upper/lower terminal of vertical rod and support bar is equipped with coupling shaft, and its lower end coupling shaft is by web joint loose joint, and its upper end coupling shaft is connected by the weight pointer with weight electronic watch.During use, experimental raw poured in hopper, hopper bears a heavy burden and moves down, and drive weight pointer to be that fulcrum moves down according to coupling shaft, the numeral that pointed scaleplate is corresponding, completes weighing of raw material; Also can be used for the experiment apparatus of lever used for physics principle.
Owing to taking technique scheme, the utility model utilizes lever principle to make can carry out the experiment of lever used for physics theory teaching, can be used as again the simple lever Libra that chemical agent weighs.Its moulding is unique, and structure is simple, reasonable in design, and application is convenient.
