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

technical field [0001] The invention belongs to children's toys, in particular a toy sundial used to demonstrate the structure and principle of the sundial. Background technique [0002] The sundial is a tool used for timekeeping in ancient my country. The projection direction and length of the sundial needle on the sundial surface are different at different times of the day. If you explain the principle of the sundial clearly in teaching, you often need to go to the scene to observe it many times. The timing demonstrates clearly. Contents of the invention [0003] In order to overcome the shortcoming that the ordinary sundial cannot demonstrate the principle of the sundial in a short time, the present invention provides a toy sundial, which can conveniently demonstrate the projection direction and length of the sundial needle on the sundial surface at different times of the day. [0004] The technical solution adopted by the present invention to solve the technical proble...
