Abstract

The invention provides an energy-saving page-turning projection pen which is composed of a projection pen shell, an energy picking pressing handle, a spring, a circular hole, a gear push rod, an innerpartition plate, a circuit board, a gear, a self-lubricating multi-layer composite bearing, a mechanical energy battery generator fixed shaft, a limiting plate, a D-shaped limiting hole, a projectionpen key and a volute spring of a mechanical energy battery. A self-lubricating multilayer composite bearing is adopted on the basis of the structure of the ZL201410221237.2 energy-saving environment-friendly projection pen, linkage components are reduced, rotation is more reliable, mechanical energy picking is more sufficient, sufficient electric energy is provided for the projection pen, autonomous power supply and long-time uninterrupted work are achieved, and the projection pen is simple in structure, reliable, economical and practical.

Description

technical field [0001] The invention relates to a page-turning projection pen, in particular to an energy-saving page-turning projection pen, belonging to the field of teaching aids. Background technique [0002] During the use of the ZL201410221237.2 energy-saving and environment-friendly projection pen, it was occasionally found that the volute spring of the mechanical energy battery would be entangled, which would affect the pickup of mechanical energy. Contents of the invention [0003] The technical problem to be solved by the present invention is: on the basis of the structure of ZL201410221237.2 energy-saving and environment-friendly projection pen, self-lubricating multi-layer composite bearings are used to simplify the interlocking system so that the interlocking system is more reliable and the mechanical energy can be picked up more fully. Provide sufficient power to realize autonomous power supply. [0004] The technical solution adopted by the present inventio...
