Description
Technical field
The utility model belongs to the desk technical field, especially relates to a kind of desk desktop inclined angle regulating mechanism.
Background technology
Desk is indispensable a kind of apparatus in our daily life, the working and learning, since ancient times, the desk desktop all is plane, people's neck whisker when writing turns forward, if the overlong time neck can produce fatigue, cause cervical spondylosis easily, very impracticable for the desk that drawing-painting is such.
Summary of the invention
The purpose of this utility model is at existing deficiency, provide a kind of and can make desktop certain visual angle that tilts when drawing writing, the physical feature that meets human body makes the people not feel tired, and the time spent desktop does not fall and ends plane a kind of desktop inclined angle regulating mechanism.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of desktop inclined angle regulating mechanism, comprise desktop, bracing or strutting arrangement, handle, described desktop top lateral mid-point is provided with a shrinkage pool, handle is set in the shrinkage pool, be positioned at handle below, the desktop back side, be provided with bracing or strutting arrangement, bracing or strutting arrangement is by Retchet gear type bracing frame one end and push plate, torsionspring, fixture connects to form through bearing pin, push plate one end engages with handle lower end protuberance, the fixture other end is fixed on the desktop through screw, be provided with the keeper that is mated on bracing frame ratchet opposite, top, the described desktop back side is provided with presses folder, and it is hinged with a body that the desktop lower end is provided with movable hinge.
Lower end, described handle back side protuberance is connected in the shrinkage pool both sides through bearing pin, and its upper end is connected with the affixed extension spring of shrinkage pool wall with the other end, and the handle front is equal with desktop.
Described Retchet gear type bracing frame is arc ratchet-like or vertical bar shaped ratchet-like.
Top, the described desktop back side is provided with one or more pressure folder, presses folder to turn 180 ° to the desktop front.
The utility model adopts the Retchet gear type support frame device to regulate the angle of inclination of desktop, and the hand control bracing frame is moved up and down.Pulling handle up, handle lower end protuberance rotates and drives push plate and pushes to bracing frame, and the ratchet of bracing frame is separated with keeper, desktop is rotated up and down and regulates the angle of inclination.Decontrol handle, bracing frame engages with keeper under the effect of torsionspring elastic force, and desktop is fixed on the required angle.From the back side, desktop top, rotate to press to press from both sides and clamp paper to the desktop front, prevent the paper displacement.When not required, can make the desktop landing equal with the desk panel.The present invention makes desktop certain visual angle that tilts, and meets the physical feature of human body, and neck did not feel tired when people were worked, simple in structure, steady firmly real, it is very flexible that desktop is adjusted angle, be applicable to student's table, family's desk, unit desk desktop angular adjustment is used.
