Description
Technical field
The utility model belongs to the teaching aid technical field, relates in particular to a kind of low pressure electric shock apparatus for demonstrating.
Background technology
Condition and reason that junior two physics teaching material gets an electric shock about low pressure provide two width of cloth pictures, make the student when understanding the physical knowledge of being learned, and intuitive is not strong.Existing demonstration teaching aid is equivalent to the movable wall chart of a width of cloth, is not easy to study and understands.
Summary of the invention
The utility model is exactly at the problems referred to above, and a kind of demonstrating visual, low pressure electric shock apparatus for demonstrating easy to operate, simple in structure are provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises base plate and manikin, its structural feature base plate is provided with transformer, fuse and two risers, is arranged with first metal wire, second metal wire, the 3rd metal wire between two risers from top to bottom successively in parallel; A hand of manikin links to each other with first metal wire, and the another hand of manikin links to each other with second metal wire, and the pin of manikin links to each other with the 3rd metal wire; First metal wire is electrically connected with second metal wire by first bulb on first switch, the manikin successively, first metal wire is electrically connected with the 3rd metal wire by second bulb on second switch, the manikin successively, the former limit of described transformer links to each other with fuse, one end of the secondary of transformer links to each other with first metal wire, and the other end of the secondary of transformer links to each other with second metal wire, the 3rd metal wire respectively.
As a kind of preferred version, at least two on first bulb described in the utility model, each first bulb series connection; At least two on described second bulb, each second bulb series connection.
As one other plant preferred version, bulb described in the utility model is the LED lamp.
The utility model beneficial effect
