Description
Technical field
The utility model relates to a kind of apparatus for demonstrating, relates in particular to a kind of ancient writing and amplifies teaching demonstration device, belongs to Chinese literature teaching aid technical field.
Background technology
The Han dynasty scholar calls modern script to lishu traditionally, literal before Qin Dynasty is called ancient Chinese prose, ancient writing is because of the remote past, the font complexity, the pronunciation variation makes people exist very big difficulty, particularly ancient writing to be difficult in to make carbon copies on the blackboard when study and explains study, read with multimedia teaching facility that to amplify back demonstration effect very undesirable, for ancient writing teaching and explanation are made troubles.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of ancient writing to amplify teaching demonstration device, amplify by in ∏ shape framework, placing convex lens, regulate to be fixed on the distance between ancient writing sample and convex lens on the square plate and can to obtain being amplified to ancient writing on the clearly sample of suitable size in the front of convex lens by rotary screw rod, can directly allow observation of students or use multimedia teaching facility directly to carry out teaching demonstration, observation, explanation.
The technical scheme in the invention for solving the technical problem is: a kind of ancient writing amplifies teaching demonstration device, it is by platen, supporting leg, screw mandrel, crank, outer end cap, interior connection cover, trapezoidal slide block, square plate, ∏ shape framework, back surface glass, convex lens, front glass, illuminating lamp is formed, below platen, be connected with supporting leg, ∏ shape framework is fixedly arranged on platen, in ∏ shape framework, to preceding square back surface glass arranged fixedly successively by the back, bull's-eye, square front glass, the inside surface of the ∏ shape framework of glass back is provided with illuminating lamp in the back, rear side centre position on platen is provided with dovetail groove, in dovetail groove, slidely connect trapezoidal slide block, the top square plate that vertically is connected with of trapezoidal slide block, internal thread at trapezoidal slide block is connected with screw mandrel, the front end of screw mandrel is connected with platen by its plush copper that is provided with, the convex shoulder that the screw mandrel rear end is provided with and outer end cap, the inner stopper of interior connection cover connects, outer end cap, interior connection cover is fixed on the back of platen successively by bolt.Be connected with crank in the through hole of described screw mandrel rear end.
The beneficial effects of the utility model are: owing to adopt convex lens the ancient writing on the sample to be carried out the effect of optics amplification and conveniently adjusted amplification, effectively solve and directly observe difficulty, manifolding difficulty and the very undesirable practical difficulty of multimedia amplification effect, for the ancient writing teaching brings great convenience, it is a kind of convenient and practical ancient writing teaching demonstration device simple in structure.
