Display device for geography teaching

Abstract

The invention discloses a display device for geography teaching. The display device comprises support rods which are parallelly arranged, a support cross bar is rotatably connected between the supportrods, a fixing rod is fixed in the middle of the support cross bar, a limit rod is fixed to one end of the fixing rod, a connecting plate is fixed on the other end of the fixing rod, two adjusting structures are respectively arranged at two ends of the connecting plate, each adjusting structure includes a small chain pulley located above the top of the connecting plate, a rotating shaft is fixedto the bottom of each small chain pulley, a rotating sleeve located under the connecting plate is fixed to the bottom of each rotating shaft, and a threaded rod is sleeved in the inner side of each rotating sleeve. By the cooperative arrangement of structures of a rotary disk, an L-shaped lockpin, a spring, the fixing rod, the limit rod and the like, switching of a display ball and display imagescan be realized, rotary displaying of the display ball can be achieved, stereo and horizontal display are combined in display, learning impression and cognition of students in geography can be deepened, and good display effect is achieved.

Description

technical field [0001] The invention relates to the technical field of teaching devices, in particular to a display device for geography teaching. Background technique [0002] In the geography teaching of the prior art, the map is a tool often used by teachers. It is mainly used to combine with the book content to help students understand, but the hanging of the map has become a major problem for geography teachers. Some special wall chart racks The appearance of the map can solve this problem, but there are still deficiencies.
