History teaching demonstration time shaft

Abstract

The invention discloses a history teaching demonstration time shaft which comprises an outer line cover, wherein a fixing sleeve is fixedly connected with the inner wall of the outer line cover; a telescopic sleeve rod is fixedly connected with the inner wall of the fixing sleeve; a pull ring is fixedly connected with one end, far away from the fixing sleeve, of the telescopic sleeve rod; a moveable sleeve ring is moveably connected with the surface of the telescopic sleeve rod; a fixed sleeve ring is fixedly connected with the surface of the telescopic sleeve rod; connecting transverse platesare fixedly connected with one sides of the moveable sleeve ring and the fixed sleeve ring. By adopting the history teaching demonstration time shaft, due to the adoption of the fixing sleeve, the telescopic sleeve rod is fixed on the outer line cover, the pull ring is matched with the fixed sleeve ring and the connecting transverse rod, and the moveable sleeve ring can be moved on the telescopicsleeve rod together when the telescopic sleeve rod is extended; as a rotating shaft and a fixing rod are combined through a bearing, a file roll can be rolled downwards, then a history teacher does not need to draw a time shaft on a blackboard for multiple times, and due to a dynamic demonstration mode, the attention degrees of students can be improved.

Description

technical field [0001] The invention relates to the technical field of teaching tools, in particular to a history teaching display timeline. Background technique [0002] In the process of history teaching, the understanding and memory of time nodes is particularly important. It is easy to confuse the first memorization. Teachers need to draw the time axis on the blackboard with traditional writing on the blackboard and explain it in an oral way to strengthen students' understanding and help students Students memorize accurately, but history teachers often don’t only bring the history of one class. If there are multiple classes, they need to draw the timeline on the blackboard multiple times. This not only increases the workload of teachers, but also the static timeline can only attract students’ attention. . Contents of the invention [0003] The purpose of the present invention is to provide a history teaching display timeline to solve the problems raised in the above-m...
