A multimedia teaching device

Abstract

The invention discloses a multimedia teaching equipment, which comprises a mounting frame. An open inner cavity is arranged in the mounting frame, and a sliding fitting box is provided for sliding in the inner cavity. There is an output threaded rod that rotates between them, and the output threaded rod is threadedly connected with the sliding fit box, and a moving motor is fixed on one side of the mounting frame, and the moving motor is dynamically connected with the output threaded rod , one side of the installation frame is provided with a bottom box. The structure of the device of the present invention is simple. This device adopts a multi-group semi-circular structure, combined with the flipping and folding between each other, the device is close to the folded state. At the same time, the head space can be expanded to form a higher structure, and the single half ring can be disassembled and replaced separately, which improves the convenience of the equipment and saves the space of the equipment, and realizes the most space-saving way. Long extension length.

Description

technical field [0001] The invention relates to the technical field of multimedia teaching equipment, in particular to a multimedia teaching equipment. Background technique [0002] Existing teaching equipment, especially when it comes to the use of projectors, due to frequent height adjustments for the use of projectors, the disadvantage of existing equipment is that when adjusting the projectors, most of them The cylindrical lift is adopted, the disadvantage of which is that the cylindrical structure occupies a large amount of space in the space, and in the vertical direction, due to the existence of the structure, it will hinder the entry and exit of people or the placement of articles, etc., and In actual use, since the straight cylinder structure mainly relies on the sliding between the cylinders when the telescopic distance changes, if a single cylinder fails, it will affect the actual work of other cylinders, so that the equipment does not have the function of height ...
