Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.As shown in Figures 1 to 8, a kind of eye-protective desk that can regulate height, capacity and desktop inclination angle, comprise table 2 and casing 1, the technical measures taked have: casing 1 frame is provided with four lowering or hoisting gears 4, lowering or hoisting gear 4 contacts with table 2, and table 2 is provided with the position limiting fence 31 for limiting head and desktop distance.Lowering or hoisting gear 4 rises or declines and table 2 can be made to change horizontal level, reaches the effect changing gradient or height, and when table Level Change, the capacity of its inside also changes thereupon; Distance when gradient changes by regulating position limiting fence 31 to adjust human body head and desktop.
Lowering or hoisting gear 4 comprises screw rod 42 and nut 41, and nut 41 and screw rod 42 screw, and screw rod 42 lower end is placed in hole corresponding on casing 1 frame.Rotate forward nut 41, screw rod 42 meeting upwards screw, thus table 2 jack-up is risen, you are as rotating nut 41, and the downward screw of screw rod 42 meeting, table 2 falls thereupon.
Above-mentioned lowering or hoisting gear 4 is located on two parallel frames of casing 1.Lowering or hoisting gear 4 can be located on the frame of front and back and also can be arranged on left and right side frame, and such being provided with is beneficial to the balance of table 2, makes to rise or decline stress equalization.
Screw rod 42 upper end is fixedly connected with ball and socket joint 43, and ball and socket joint 43 is semicolumn, and ball and socket joint 43 is placed in the fossa glenoid on table 2, and the face of cylinder of ball and socket joint 43 is parallel with table 2 side.When the action of current lowering or hoisting gear 4 causes table 2 to tilt, ball and socket joint 43 is rotated relative to table 2 in fossa glenoid, the generation of the transverse fold power to screw rod 42 preventing the inclination because of table 2 from producing; The both sides parallel surface inserting the ball and socket joint 43 in table 2 fossa glenoid limits moving left and right of table 2.
Nut 41 upper surface flushes with casing 1 frame upper surface.Nut 41 counter-rotating can make table 2 be affixed on the upper surface of nut 41, also makes table 2 contact with the frame upper surface of casing 1 simultaneously, thus makes three, desk stuffy.
Position limiting fence 31 one end is provided with first sawtooth 31a, and table 2 is provided with arc groove, is provided with second sawtooth 21a in groove, and position limiting fence 31 and table 2 are connected by sawtooth.Reach by the sawtooth occlusal position changed between position limiting fence 31 and arc groove the object changing position limiting fence 31 angle of inclination, while change position limiting fence 31 angle of inclination, it highly also changes simultaneously.
Arc groove both sides are positioned at table 2 and are provided with gathering sill 21b, and gathering sill 21b is opened on the side of table 2, and position limiting fence 31 and axle 33 are rotationally connected, and the two ends of axle 33 are placed in gathering sill 21b.Axle 33 limits moving up and down of position limiting fence 31.Be with moving axis 33 to move along gathering sill 21b when laterally releasing position limiting fence 31 simultaneously, first sawtooth 31a is separated with second sawtooth 21a, pull position limiting fence 31 after axle 33 anglec of rotation, to push rear first sawtooth 31a be engaged with second sawtooth 21a, thus make position limiting fence 31 obtain new angle of inclination and height.
Table 2 is fixed with arc elastic sheet 32, the arc core of arc elastic sheet 32 is towards groove, and arc elastic sheet 32 contacts with position limiting fence 31.Arc elastic sheet 32 is pressed in position limiting fence 31 on table 2 and prevents it from coming off.
Most preferred embodiment of the present utility model is illustrated, and the various change made by those of ordinary skill in the art or remodeling all can not depart from scope of the present utility model.
