Problems solved by technology

[0003] However, in the teaching process, in many cases, there will be incomplete projection of the projector, and the projection equipment cannot be adjusted independently. In many cases, technicians are required to debug, which delays teaching time, affects teaching quality, and is not conducive to teaching; Some projection equipment does not have a cooling device, which causes a large amount of heat to accumulate when the projector is used for a long time, causing internal damage to the equipment and affecting normal use

Abstract

The invention discloses an intelligent teaching projection device for management science and engineering, which includes a bottom plate, a pillar and a projector housing, a plurality of pillars are fixed around the top of the bottom plate, and a mounting plate is fixed on the top of the pillar. A spherical seat is arranged in the middle of the upper left side of the base plate, and a spherical groove is arranged above the interior of the spherical seat, and a universal ball head is arranged inside the spherical groove, and the universal ball head is rotatably connected with the spherical groove. The upper end of the universal ball head is fixedly connected with the left end of the projector housing. A control box is arranged in the middle above the bottom plate. A groove is arranged on the right side above the bottom plate. The front end of the tank is fixed with a first electric telescopic rod, and the output end of the first electric telescopic rod is fixedly connected to the front end of the block. The product of the present invention has simple structure, multiple functions, good heat dissipation performance, and can effectively control the position of the projector. Make adjustments to facilitate promotion and use.

Description

technical field [0001] The invention relates to the technical field of teaching facilities, in particular to an intelligent teaching projection device for management science and engineering. Background technique [0002] A projector is an optical instrument that uses optical elements to magnify the outline of a workpiece and project it onto a screen. It can be used for profile measurement with transmitted light, and can also be used to measure the surface shape of a non-through hole and observe the surface of a part with reflected light. The projector 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 instrumentation and watch industry. The portability of the projector makes up for the...
