Description

Self-adjustable chair table integrated health computer desk

Technical field

The present invention relates to a kind of computer desk designing technique, is a kind of adjustable height and angle of inclination self-adjustable chair table integrated health computer desk specifically.

Background technology

Have the computer desk of selling on the market now, compare with traditional desk, its structure difference is little, it just changes intermediate drawer under the desktop into the convenient limit-type pull drawer of placing computor-keyboard, remainder repacks into and is suitable for placing host computer, the ups power voltage-stablizer, and the drawer (cabinet) of CD or disk etc. and computer corollary equipment, in addition, return the office wheelchair that has soft backrest and soft cushion (seat base has the wheelchair of little runner) special-purpose in the staffing of using computer, above-mentioned computer desk and supporting office wheelchair thereof, more suitable for staff interim or short time use computer office or inspection information, in use there is no sense of discomfort, but to many one dried be exactly the personnel that computer is used in half a day even eight or nine hours long-time operation, as the keyboarder, the specific computer duty personnel, and the teenager's computer player who plays computer game for a long time, existing computer desk and supporting wheelchair also are not suitable for, reason is the angle of inclination of these computer desks at present and highly is difficult to be adjusted to the state that can be fit to human body needs and comfortable use, for example when operating computer personnel (or game player) because of use computer of a specified duration and when wanting at second recumbency body of the situation that does not influence work on (or playing games), just can't operate effectively without a break, like this, these personnel will maybe must not differ unawares and connect several hours and holding out in spite of difficulties the sitting posture that is maintained fixed for a long time operation of working hard, and cause hunchback, tired, the unfavorable factor that influence such as sense of discomfort is healthy.Really, along with constantly popularizing and development of computer, people also wish to design early more and more practical comfortable health care computer table.

The objective of the invention is to design a kind of self-adjustable chair table integrated health computer desk, make and to have the computer display screen height and the inclination angle is all adjustable, long-time comfort is good, the long-time hunch of teenager computer operater in favourable the preventing, favourable antifatigue and physical and mental health.

The present invention realizes with following technical scheme: it comprises table leg frame, base, desktop, computer equipment accommodation space: as keyboard and the ccontaining drawer of CD, the ccontaining place of main frame, be positioned over the ccontaining place of display (screen) of desktop, with supporting (the having soft back rest cushion) seat of computer desk, it is characterized in that seat and table leg frame are installed on the frame-type upper spider seat as lifting platform jointly, the tail end of frame-type upper spider seat and base (lower bearing bracket seat) are connected through the hinge, between lower bearing bracket seat (being base) and frame-type upper spider seat, be provided with a lowering or hoisting gear (mechanism), on table leg frame, be provided with a lifting and descend

Control device, control device can be controlled lowering or hoisting gear, and lowering or hoisting gear can drive frame-type upper spider seat and make shuttle-type slow lifting (rising) or down maneuver round hinge pin.

Above-mentioned technical solution of the present invention can also further be specially:

One, described lowering or hoisting gear can be to adopt by motor, gearbox (or band speed changer motor), screw mandrel, feed screw nut's elevating mechanism that nut and movable supporting link member constitute, wherein motor and gearbox (also claiming reduction box) are fixedly mounted on the lower bearing bracket seat (base), be connected with the power output shaft of motor by gearbox with the nut fit screw rod, one end of described two movable supporting connecting rods (also claiming rocking lever) is hinged on the front end (or head end) of frame-type upper spider seat, the other end of two movable supporting connecting rods is articulated in the two ends of (can prolong lower bearing bracket seat guide rail groove before and after move around) activity push-and-pull cross bar respectively, the push-and-pull cross bar is fixedlyed connected with nut and can be made same back and forth moved further with the nut interlock, lower bearing bracket seat (base) is gone up design the guide rail that cooperates with activity push-and-pull cross bar, the two ends guide wheel of push-and-pull cross bar moves around before and after can prolonging this guide rail groove work, during work, motor output shaft drives screw mandrel by reduction box and rotates, screw mandrel drives nut again and the push-and-pull cross bar moves around on the guide rail of base, thereby the support link (rocking arm pavilion) that makes the push-and-pull cross bar promote its two ends again drives frame-type upper spider seat and makes swing type rise slowly (lifting) or down maneuver, realized that finally the height of the computer desk of tables and chairs disjunctors and computer display screen thereof and angle of inclination are all adjustable (after screw mandrel drives nut and moves into place, circuitous travel switch can stop lifting work), make the people keep being in the best situation of self sensation and continue operating computer.

Two, described lowering or hoisting gear also adopts the hydraulicefficiency elevation structure of being made up of hydraulic cylinder and piston push rod, wherein hydraulic cylinder is movably hinged and is installed on the lower bearing bracket seat (base), the top of the piston push rod (playing the support link effect) that is used with hydraulic cylinder is hinged on frame-type upper spider seat front end (or head end), and its lifting operation principle is analogous to (figure slightly) of feed screw nut's elevating mechanism.

Three, on described frame-type upper spider seat, be provided with the guide rail groove with the installation place of seat bottom, make (soft backrest) seat after installing other seats such as (or) massage armchairs can prolong guide-track groove and move around before and after doing, to adapt to the optimum reelability quality demand of human body when taking.

The present invention adopts the integrated coordinated type of chair table to be installed on the frame-type upper spider seat as hoistable platform, within it under the drive of the elevating mechanism of portion, computer desk and table leg frame thereof can be made the swing type lifting action of tilt adjustable together with frame-type upper spider seat, it is good to make the computer operater face the long-time comfort of display (screen) of tilt adjustable, teenager's computer player's physical and mental health in the advantageous particularly prevents that hunchback and antifatigue effect are good.
