Novel computer desk
Technical field
The present invention relates to a kind of novel computer desk.
Background technology
In today of the continuous progress of modern science and technology, computer has become the indispensable companion of people's routine work life, along with improving constantly of computer popularity rate, indicates that the intelligentized epoch of automated informationization arrive.Yet be engaged in the personnel of computation for a long time owing to be subjected to the limitation of existing computer desk, force and oneself keeping a kind of more stiff posture for a long time, in the course of time just suffer from scapulohumeral periarthritis or cervical spondylopathy easily, how to prevent that this class occupational disease from being the problem that people pay close attention to.Can rotate at present and can regulate office revolving chair highly makes the state of operating computer obtain certain change, the present invention intends the improvement design by computer desk, with the further working environment that improves operating computer, avoid or reduce the incidence probability that causes scapulohumeral periarthritis and cervical spondylopathy because of the long-time operation computer.
Summary of the invention
The invention provides a kind of novel computer desk.Promptly on common computer desk, increased keyboard rear portion lift adjustment function and mouse supporting plate moves forward and backward and corresponding up-down adjustment function.In conjunction with the function that office revolving chair possessed, can draw the combination of numerous different operating stations, people can the time carry out suitable adjustment in operation according to the state of oneself, satisfying the demand of health comfort level, thereby lessen fatigue, and reduce and bring out scapulohumeral periarthritis and cervical spondylopathy.
In order to address the above problem, the invention of this reality is achieved through the following technical solutions, and it is made up of panel, slide rail, riser, double-screw bolt, lift block, pad, locking nut, drawer plate, lifting knob, pivot pin, drawer panel, carriage, liner plate, hinged, hinged bar, adjusting nut, supporting plate, T shape screw, hinged plate, handwheel, chute.Panel, riser, liner plate are formed the main body of desk, establish the drawer of shelving keyboard in a side of middle part riser, and drawer is made up of drawer plate and drawer panel, and drawer is connected and keeps relatively-movable position relation with riser by slide rail.Two carriages of putting keyboard be arranged in parallel on the drawer plate, carriage is the rectangle rod member, one end is established an aperture, adopt hinged mode to be installed in drawer panel one side, the other end is the tenon of two shoulder symmetries, place, the wide plane of tenon establishes a slotted eye, the slotted eye direction is parallel with aperture, carriage is connected with lift block by pivot pin, lift block is that an end is established the rectangular block shape part that the screw other end is established concave indentation, the concave indentation end also is provided with the aperture that pivot pin is installed, the tenon of concave indentation and carriage is identical substantially, and the carriage tenon embeds the lift block concave indentation, penetrates aperture and slotted eye with pivot pin, make carriage and lift block when pivot pin rotates, pivot pin still can be done relative slippage along the tenon slotted eye.Double-screw bolt is stepped, screw thread is established at two ends, big end screw thread and the engagement of lift block screw, middle smooth and round section diameter and drawer plate installing hole matched in clearance, and with pad, locking nut, lifting knob it is installed on the drawer plate, the effect of locking nut be regulate the axial float between double-screw bolt and drawer plate and will promote knob locked on double-screw bolt.Install ready after, rotate and upgrade the knob lift block and just can move up and down, do corresponding lifting thereby drive carriage one end, to satisfy the demand of people to the different gradients of keyboard.At the opposite side of middle part riser, use the parallel-crank mechanism principle, the supporting plate front and back all can suitably be regulated up and down.Supporting plate is a rectangular flat, be connected with panel with hinged, hinged bar, common and panel be arranged in parallel, the hinged bar in supporting plate front end both sides is a split-type structural, first and second install reverse thread, screw in being provided with the adjusting nut of reverse thread, the rotation adjusting nut can change the relative length of hinged bar.Hinged plate is provided with former and later two hinged holes, preceding hinged hole and hinged bar are hinged, hinged hole, back and chute, T shape screw is hinged, chute is fixed on the riser, T shape screw embeds in the chute of arc, can do circular motion along chute, T shape screw is threaded with handwheel, the arc radius system and the hinged bar equivalence of front end of chute, the condition of parallel-crank mechanism is satisfied in set-point, the center of circle, chute is that supporting plate is the arc track of the parallel-crank mechanism rear fulcrum of rod member, supporting plate will keep level along runner movement, the track of supporting plate translation has formed a zone that front and back move up and down, and people can choose at random the position of supporting plate in this zone, and is locked with handwheel.In addition, the inclination angle of supporting plate front and back can also be set, to improve the comfort level of human body by the rotation adjusting nut.In sum, the present invention has the attitude that a plurality of point of adjustment can be adjusted operating computer for people, the personnel of long-time operation computer can carry out the adjustment of operating attitude at any time according to self tired situation, alleviate the strain degree of body local position, to stop and to reduce the generation of scapulohumeral periarthritis, cervical spondylopathy.
