Technical field:
The utility model belongs to field of furniture, particularly a kind of computer desk Keyboard supporting board linkage lifting.
Background technology:
Existing computer equipment is very universal, and especially the multimedia computer take liquid crystal display as representative, merged various functions such as office, study and video, satisfies the occasions such as family and teaching, realizes human-computer interaction, remote dialogue etc.The desk of tradition computer desk and audio-visual education room, computer screen adopts outer being exposed on desktop mostly, can't collect, and takies desk-top space, especially when not using computer.Along with the renewal of the equipment of computer, especially liquid crystal display has replaced Traditional CRT Display, takes up room little and more light, for the collection design of display offers convenience.For this reason, how to solve liquid crystal display collection and keyboard collection space contradiction, and linkage action, the object that the utility model is studied namely become.
Summary of the invention:
The purpose of this utility model is that a kind of desktop of design is built-in liquid crystal display and a keyboard, and by the computer desk Keyboard supporting board linkage lifting of renovating the lifting of interlock keyboard of fixing display.
Technical solutions of the utility model are achieved in that a kind of computer desk Keyboard supporting board linkage lifting, comprise renovating and Keyboard supporting board of desktop, inner surface fixing display; Desktop offers window, cover turnover shaft is positioned on the fixed part of window both sides, and renovating the lid that can coincide is located on described desktop window, it is characterized in that Keyboard supporting board is located in window, both sides are respectively by the link supports of two parallel distributions, two small ends of homonymy are movably articulated in respectively on Keyboard supporting board, and the lower end is hinged on respectively on the fixed part of desktop downside; The described both sides of renovating are fixed with respectively driving chip, offer driver slot on driving chip; The Keyboard supporting board both sides are respectively equipped with a protruding pin, and this protruding pin is located in described driver slot; Renovate the process of opening, this driving chip interlock Keyboard supporting board rises.
Driver slot in described driving chip is continuous shaped groove, includes lifting and drives section and supporting section.
In the connecting rod of two of described both sides, a connecting rod of correspondence, in the bottom hinged with the desktop fixed part, be fixed together by a cross bar association.
Described driving chip is provided with the axle eye, and desktop window both sides fixed part correspondence is provided with axle bed, passes axle eye on driving chip by the bearing pin on axle bed, forms to renovate the movable axis location on the table.
Two of described homonymies connecting rod bottom is movably articulated in respectively on a crossbeam, and crossbeam is fixed on the fixed part of desktop downside.
The utility model utilizes the driving chip of renovating dexterously, related Keyboard supporting board, lifting by shaped groove on driving chip drives the design attitude that section drive Keyboard supporting board rises to suitable work, and the supporting section of shaped groove both can keep the support to Keyboard supporting board, allow again to renovate the adjusting of doing again angle, to satisfy differing heights user's demand; And when collection, the parallel rod of support keyboard supporting plate, can equally produce synchronous inclination to reduce height by similar four connecting rods, make Keyboard supporting board to be concealed in and renovate the below, all do not account for desktop limited space, when making without computer, desktop and common desk or desk are as good as, especially be suitable as on the desk of audio-visual education room and use, also can improve dustproof, the anti-theft feature of display and keyboard.
