A fully adjustable teaching projector that plays historical content and adds fun

Abstract

The invention relates to the technical field of teaching appliances, in particular to a fully adjustable teaching projector that plays historical content to increase interest, including a projector. As for the lifting mechanism, the bottom end of the inner chamber of the adjustment box is provided with a rotating mechanism, and the bottom end of the rotating mechanism is connected with the projector by screws. The play history content is more interesting and the fully adjustable teaching projector drives the first gear to rotate through the rotation of the first motor in the lifting mechanism to push the inner cylinder of the first rotating shaft to rotate, and the bottom end of the screw will move up and down in the direction of the vertical axis. The height of the projector can be adjusted according to teaching requirements. The rotation mechanism drives the second gear to rotate through the second motor to push the third gear to rotate. The rotation of the third gear drives the cylinder to push the projector to rotate, and the angle and direction of the projector can be adjusted, which is convenient for teachers The use improves the teaching efficiency and has strong practicability.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a fully adjustable teaching projector capable of playing historical content and increasing interest. Background technique [0002] A projector is an optical instrument that uses optical elements to enlarge the contour of a workpiece and projects it onto a video screen. It can use transmitted light for contour measurement, and can also use reflected light to measure the surface shape of a non-through hole and observe the surface of a part. Projection The instrument is especially suitable for measuring complex contours and small workpieces, such as watch parts, stamping parts, electronic components, templates, molds, threads, gears and forming tools, etc. It has high inspection efficiency and is easy to use. It is widely used in measuring rooms and production workshops. It is especially suitable for the instrument and clock industry. A projector, also known as a project...

[0002] A projector is an optical instrument that uses optical elements to enlarge the contour of a workpiece and projects it onto a video screen. It can use transmitted light for contour measurement, and can also use reflected light to measure the surface shape of a non-through hole and observe the surface of a part. Projection The instrument is especially suitable for measuring complex contours and small workpieces, such as watch parts, stamping parts, electronic components, templates, molds, threads, gears and forming tools, etc. It has high inspection efficiency and is easy to use. It is widely used in measuring rooms and production workshops. It is especially suitable for the instrument and clock industry. A projector, also known as a projector, is a device that can project images or videos onto a screen. It can communicate with computers, VCD, DVD, BD, game consoles, DV, etc. through different interfaces. Connect and play the corresponding video signal. Projectors are currently widely used in homes, offices, schools and entertainment places. In the existing teaching, history has become a necessary subject for teaching. History records and explains the historical events and time of human progress. History, the origin of things and past facts. For many students, history is a relatively boring subject, so blackboard writing and textbooks alone can no longer meet the current teaching needs. The projector came into being and received a lot of attention Widely promoted, but the existing teaching projectors are fixed on the roof or placed on the desks, and the angle and height can only be fine-tuned in a small range, and the angle and height cannot be adjusted in all directions. To achieve a better teaching effect, it cannot meet the current teaching needs. Now a fully adjustable teaching projector that plays historical content and adds fun is needed to solve the above problems
