Description
Technical field
The utility model relates to a kind of display unit for multimedia teaching.
Background technology
At present, the display such as television set, liquid crystal display has become the main product of display screen gradually, and in order to the appearance looks elegant pursuing display is small and exquisite, a lot of company all tries one's best and reduces the overall dimension of flat panel products.But existing commercially a lot of wall hanging function is all by a large wall hanging rack and the post of riveted joint riveting thereon realizes, and this structure exists following not enough: this infrastructure product inside takes up room greatly; A lot of button pcb board is pre-fixed on key support by screw or grab in advance, considerably reduces production efficiency; The wall hanging rack of this kind of structure is fixed on back cover by tapping screw, and assembly process is many, and production efficiency is low.
And due to the position of button assembly of the prior art in flat-panel monitor and structure thereof, make the assembling of its button assembly need screw to fix or the mode of melt plastic cement, this kind of technique feed consumption consuming time, adds manufacturing cost; Reprocess or do over again once batch, the button assembly of screw fixed form, needing first to dismantle screw, replace with qualified key support or button, and then fixing screwing, add maintenance cost.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, a kind of display unit for multimedia teaching that the utility model provides, to simplify display unit production technology, reduces the manufacturing cost of display unit.
For solving the problems of the technologies described above, the utility model scheme comprises:
A kind of display unit for multimedia teaching, it comprises display, wherein, the side of display housing is provided with the peristome for adaptive press button mechanism, and press button mechanism comprises key support and is provided with the key base of button, this key support and key base suitable, this key base is provided with at least two catchings on the side of bottom, catching is unsymmetric structure, and this key support is provided with and the catching groove of adaptation corresponding with catching, key support is arranged in peristome; The rear surface of display housing evenly arranges at least three through holes, and each through hole is configured with a wall hanging bolt, and wall hanging bolt one end is provided with spiro union portion, and this spiro union portion is passed through hole and wall hanging bolt and display housing is fixed together by nut.
Described display unit, wherein, the above-mentioned wall hanging bolt other end is provided with the fixed part for being fixed on wall.
Described display unit, wherein, is provided with packing ring between above-mentioned spiro union portion and nut.
Described display unit, wherein, above-mentioned key base is provided with at least one row's button, key support is provided with the button frame for accommodating button.
Described display unit, wherein, above-mentioned key base is provided with three catchings on the side of bottom, and catching is unsymmetric structure, and this key support is provided with and the catching groove of adaptation corresponding with catching, the notch of this catching groove is rectangle.
A kind of display unit for multimedia teaching that the utility model provides, key base and key support increase catching and catching groove, catching and catching groove adaptation use the easy assembling achieving key support and key base, exempt the loaded down with trivial details flow process that screw assembles and melt plastic cement mode is assembled, simplify display unit production technology, and multiple through hole is set on the trailing flank of display casing, wall hanging bolt is assembled together by the multiple through hole on back cover and back cover, and between bolts and nuts, packing ring is set, then the urgent nut of electric screw driver is used, structure of the present utility model is simple, eliminate wall hanging rack, do not increase other parts, and it is easy to assembly, with low cost, improve the production efficiency of display, reduce the cost of manufacture of display unit.
