Abstract

The invention discloses a toy sundial, belongs to toys for children, and particularly relates to the toy sundial for demonstrating the structure and the principle of a sundial. The toy sundial is characterized by comprising a semi-spherical base and a semi-circular handle. The top face of the base is a sundial face, a sundial hand perpendicular to the sundial face is mounted in the center of the sundial face, time scale marks which divide the sundial face into 12 equal parts are arranged on the sundial face, and each part represents twelve hours. A circular ring-shaped handle sleeve is arranged at the lower end of the handle, sun simulating lights are arranged on the inner side of the handle from the sundial face to the highest point of the handle, the distance of every two sun simulating lights is 10 degrees, a ring-shaped sleeve inner protrusion matching with a base groove in the upper edge of the base is arranged on the ring-shaped handle sleeve, and the handle can rotate around the base for 360 degrees. The toy sundial belongs to astronomy teaching tools and intelligent toys and has the advantages of being simple in structure, portable and capable of combining education with fun.

Description

The toy corona

Technical field

The invention belongs to toy for children, particularly be used for demonstrating the toy corona of corona structure and principle.

Background technology

Corona is that Ancient Times in China is used for the instrument of timing, and projecting direction difference, the length difference of different time sundial pin on the sundial face if make the principle of corona clear in teaching, often needs repeatedly to arrive field observation in one day, can't be clear in short time demonstration.

Summary of the invention

In order to overcome the existing deficiency that can't demonstrate gnomonics in the short time of common corona, the invention provides a kind of toy corona, this toy corona can be demonstrated projecting direction and the length of different time sundial pin on the sundial face in one day easily.

The technical solution adopted for the present invention to solve the technical problems is: a kind of toy corona, it is characterized in that: formed by the base of semicircle sphere and the handle of semi-round ring shape, the end face of base is the sundial face, the sundial pin vertical with the sundial face is equipped with at sundial face center, the sundial face is provided with the time scale line that is divided into 12 parts, represent 12 division of day and night, the handle lower end is provided with circular handle annular cover, a simulation sunlight lamp is equipped with from sundial face to per 10 degree of handle peak in the handle inboard, the handle annular puts and is provided with the annular cover inner process that matches with the base groove of base upper periphery, and handle can be around base 360 degree rotations.

In the described base battery is housed, is equipped with 2/3 in the base groove and encloses conductive electrode, all the other are that insulating materials is made, and annular cover inner process one end contacts with conductive electrode, and the other end links to each other with the inboard lead of simulating on the sunlight lamp of handle.

Independently switch is equipped with in the handle outside of described every simulation sunlight lamp correspondence position respectively, and simulation sunlight lamp line both sides are carved with the time scale line respectively.

The using method of toy corona is handle to be equipped with simulation sunlight lamp one side turn to graduation mark sometime, press the switch of the simulation sunlight lamp of corresponding time, simulation sunlight light irradiation sundial pin and the projection that produces the sundial pin at the sundial face, position and switch simulation sunlight lamp according to the continuous conversion handle of above-mentioned steps, just can demonstrate out the projection in sundial face formation different length and direction in the different time of sundial pin visually, can make people clearly understand the operation principle of corona.

The invention has the beneficial effects as follows provides a kind of astronomic knowledge educational aid simple in structure, portable and puzzle, teaches through lively activities.
