The content of the invention
The technical problems to be solved by the invention are that the spacing of existing integral type desk and chair and angle are usually fixed, right
For all different user of stature build, the inappropriate integral type desk and chair of spacing is run into, sits up and often less relaxes
The problem of suitable, is, and it is an object of the present invention to provide integral type desk and chair adjustable in pitch, solves the above problems.
The present invention is achieved through the following technical solutions：
Integral type desk and chair adjustable in pitch, including first base and second base, are provided with first in first base
Strut, the one end of first support bar away from first base are provided with desk body, are provided with second support bar in second base, second
The one end of strut away from second base is provided with seat, and seat can be rotated around the axis direction of second support bar, and described
Hydraulic drive mechanism and retractable support mechanism are provided between one base and second base.
Under the action of hydraulic drive mechanism and retractable support mechanism, it can adjust between first base and second base
Spacing between spacing, i.e. desk body and seat, user, to adjust sitting posture, can also carry according to self-condition swiveling seat
High degree of comfort.
Further, the desk body is the cavity of open top inner hollow, and its top is hingedly provided with lid.
Further, the retractable support mechanism includes several hinged connecting rods successively.
Further, the hydraulic drive mechanism includes hydraulic cylinder and piston rod, and piston rod one end is located in hydraulic cylinder, and
It can be moved in hydraulic cylinder, the one end of piston rod away from hydraulic cylinder is connected with the second base, and hydraulic cylinder is away from piston rod
One end be connected with the first base.
Hydraulic drive mechanism is a kind of industry that can play the functions such as support, buffering, braking, height adjusting and angular adjustment
Accessory, its operation principle are to be filled with gas mixture in closed hydraulic cylinder, make pressure superatmospheric in cavity
Several times or tens times, work is realized so as to the pressure differential produced less than the cross-sectional area of piston using the cross-sectional area of piston rod
The movement of stopper rod, due to the fundamental difference in principle, hydraulic drive mechanism has significant advantage, speed phase than common spring
To slow, dynamic force change less, be easy to control, and hydraulic drive mechanism is using high-pressure oil gas mixture as power, in whole work
It is constant to make support force in stroke, and has cushioning effect, this is the maximum feature for being superior to common spring, hydraulic driving machine
Structure is easy for installation, service free safe to use.
Further, the hydraulic drive mechanism is located at the top of the retractable support mechanism.
Further, it is both provided with the universal wheel with auto-lock function under the first base and second base.
Further, the both sides of the hydraulic drive mechanism are both provided with auxiliary telescopic bar, make first base and the second bottom
The movement of seat is more stablized.
Compared with prior art, the present invention have the following advantages and advantages：
Present invention integral type desk and chair adjustable in pitch, can under the action of hydraulic drive mechanism and retractable support mechanism
To adjust the spacing between first base and second base, i.e. spacing between desk body and seat, user can also be according to certainly
Body situation swiveling seat, to adjust sitting posture, improves comfort level.
