Description

Technical field [0001] The invention relates to a concealed magnetic structure for a touch all-in-one machine without screws before removing an infrared touch frame. Background technique [0002] At present, the front-disassembly infrared touch of the touch teaching all-in-one on the market is fixed by either the front lock screw or the back screw. The disadvantages of these two fixing methods are: the front lock screw fixing structure too affects the front appearance, it is aesthetically unsightly, and the infrared touch is maintained later. The frame is relatively troublesome; although the structure of the back lock screw is much better in appearance than the structure of the front lock screw, it is also more troublesome to maintain the infrared touch frame in the later period, and you need to remove too many screws, such as authorization in similar fields The patent with the announcement number CN 203181082U, a structure of a computer and TV touch all-in-one machine, the body ...
