Abstract

The invention discloses a projector supporting frame for teaching, and belongs to the field of educational appliances. The projector supporting frame for the teaching comprises a bottom supporting disc, wherein a supporting circular pipe is fixedly welded to the middle part of the upper end of the bottom supporting disc; a receiving box is fixedly connected to the upper end of the supporting circular pipe; an adjusting threaded rod is inserted in an upper circular hole; the lower end of the adjusting threaded rod penetrates through a lower circular hole; a U-shaped mounting plate is fixedly welded to the upper end of the adjusting threaded rod; L-shaped clamping plates are correspondingly and movably arranged on the two sides of the upper end of a transverse plate of the U-shaped mountingplate; a projector body is clamped between the two L-shaped clamping plates; and a movable reverse cover is hinged to one side of the upper end of the receiving box. According to the projector supporting frame, the projector is convenient to fix and disassemble, the height and the angle of the projector can be adjusted, at the same time, the projector can be received, and very good dust-proof andprotective effects on the projector can be realized.

Description

technical field [0001] The invention relates to the field of teaching appliances, in particular to a teaching projector bracket. 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. Teaching The projector is commonly used, and the installation of the projector is usually fixed on the projector bracket, but the traditional projector bracket is very inconvenient for the height adjustment and angle adjustment of the projector; the projector is installed on the bracket, without The storage structure stores it, and it is easy to accumulate dust when it is placed. When the projector is not in use, people walk around and easily knock over the bracket, causing the projector to fall and cause losses;...
