Problems solved by technology
[0003] The projection equipment needs to be plugged with multiple plugs, and the plugs are mostly directly inserted into the socket without any fixing measures. During the long-term use of the installation, problems such as loose plugs often occur, which affect the smooth progress of teaching activities, and the high installation position of the projection equipment is not convenient. debugging
At the same time, most of the existing projection equipment is integrated with the fixing rod. When it is fixed to the ceiling, the projection equipment needs to be lifted together, which is very inconvenient to install; and the installed projection equipment cannot be adjusted in position, so it needs to be positioned accurately during installation. further increases the difficulty of installation

The invention discloses projection equipment for multimedia teaching, and the equipment comprises an equipment body with a fixed rod at the top, wherein one side of the equipment body is provided witha plurality of plugging ports, each plugging port is provided with a fastening mechanism, and each fastening mechanism comprises a clamping part for supporting and fixing a plug, and a fixing part for fixing the clamping part. The clamping piece is hinged to the equipment body, the clamping piece and the fixing piece are detachably fixed and are fixed to the two sides of the inserting opening respectively, and the clamping piece can be turned over by being hinged to the equipment body and is fixed to the fixing piece. After the plug is plugged, the wire at the plug end is firstly clamped andsupported through the clamping piece, so that the guide of the plug end is in a flat state, the tension of the wire to the plug is reduced, the falling risk of the plug is reduced, and meanwhile, theclamping piece also has the effect of pressing and buckling the plug in the plugging port.
Description
technical field [0001] The present invention relates to the technical field of projection equipment, and more specifically, relates to a projection equipment for multimedia teaching. Background technique [0002] As a kind of teaching equipment for teaching, multimedia projection equipment has been widely used in schools at all levels. Most of the existing multimedia projection equipment is hoisted on the ceiling of the classroom, and the projection screen of the projection equipment is projected onto the canvas in front of the classroom. [0003] The projection equipment needs to be plugged with multiple plugs, and the plugs are mostly directly inserted into the socket without any fixing measures. During the long-term use of the installation, problems such as loose plugs often occur, which affect the smooth progress of teaching activities, and the high installation position of the projection equipment is not convenient. debugging. At the same time, most of the existing pr...
