Wherein this motor is to turn this hinged arm via one worm screw-worm gear.
Wherein the force-output shaft of this motor is perpendicular to this hinged arm; Worm screw in this worm screw-worm gear and worm gear are to be located at respectively on the force-output shaft and this hinged arm of this motor.
Wherein this worm screw-worm gear is to be located at partially by this hinged arm one end place; This motor is this elevating bracket inboard that is fixedly arranged on should worm screw-worm gear one side, and the position is below this table.
Wherein this pedestal include paste ground about two pin that crouch, extend upward a dorsal column from the pin rear end of respectively should crouching, linking between this two dorsal column has a back wall; Aforementionedly be located at that two tooth rows of two sides are to be located at respectively on this two dorsal column about pedestal.
Wherein respectively this dorsal column is to be rectangular tube, and its front tube mask has a long slot bore that extends vertically, and tube wall respectively bends inwards in these long slot bore two sides and extends clamping plate; Respectively this elevating bracket has the side plate that a plate face is erect, this side plate rear side is inserted in this dorsal column by this long slot bore, and be subjected to support about this second splint, and following thereon two ends of the side plate rear side that is positioned at this dorsal column inside, respectively at the plate face two sides bearing that respectively is pivoted, the side face of these bearings is connected on the internal face of this dorsal column.
Wherein respectively this dorsal column is cut out some horizontal short slots in cutting out between its tube wall front etc., forms aforementioned tooth row.
Below act one preferred embodiment cooperation is graphic is elaborated to the utility model, wherein:
Fig. 1 is the stereogram of the utility model one preferred embodiment;
Fig. 2 is the front view of the utility model one preferred embodiment;
Fig. 3 is the left side view of the utility model one preferred embodiment; And
Fig. 4 is the top view of the utility model one preferred embodiment.
As shown in the figure, the electrodynamic type desktop section of the nothing lift adjustment structure that provides of the utility model one preferred embodiment includes:
One pedestal 10, be by the left and right sides parallel paste two of ground crouch pin 11, constituted from this two back wall 13 that crouches upwardly extending two dorsal columns 12 in pin 11 rear ends and be linked to 12 of this two dorsal columns respectively, firmly frame stands on the ground; This two dorsal column 12 is the rectangular tubes for metal material, and its front tube mask has a long slot bore 14 that extends vertically, and tube wall respectively bends inwards in long slot bore 14 2 sides and extends clamping plate 15 (Fig. 4); This two dorsal column 12 is established a tooth row 16 that extends vertically (annotate: present embodiment is that long slot bore 14 is cut out some horizontal short slots 17 to form aforementioned tooth row 16 with a left side or to cut out between the tube wall on the right side etc.) respectively at the inner side edge of front tube face, all maintains preset distance (wherein Shang Fang blank space is shorter) between two ends up and down of this tooth row 16 and dorsal column 12 top bottoms;
Two elevating brackets 20, with about relative form be located at two dorsal columns, 12 front sides of pedestal 10 respectively, each elevating bracket 20 has the side plate 21 that a plate face is erect, side plate 21 rear sides are inserted in the dorsal column 12 by the long slot bore 14 in dorsal column 12 fronts, and supported by the clamping plate about 15 of long slot bore 14 2 sides, be positioned at following two ends of side plate 21 rear sides of dorsal column 12 inside thereon, respectively at the plate face two sides bearing 22 (Fig. 3) that respectively is pivoted, the side face of these bearings 22 just is connected on the front and back internal face of dorsal column 12, make elevating bracket 20 can be stably along axially slippages up and down of dorsal column 12; The elevating bracket 20 in left side extends a motor base plate 23 in side plate 21 inner faces;
One table 30, rectangular, left and right sides dual side-edge is fixed in this two elevating brackets, 20 end faces respectively, can rise or descend with elevating bracket 20; Desktop in the present embodiment is to be level, and the utility model also can be designed to desktop support with favored policy, perhaps table is partly changed with engaging of elevating bracket and adopt the movable structure of commonly using drawing bench and so on, make the desktop inclination angle can supply to adjust, also can below table, set up drawer, keyboard slide etc. in addition, all true selection, the non-the utility model emphasis executed of these kenels of thought;
One hinged arm 40 (Fig. 2-Fig. 4), with level to the side plate 21 inclined to one side rear side places that its two end are hubbed at this two elevating bracket 20 respectively, but the original place rotation; These hinged arm 40 2 ends respectively set firmly a gear 41, this two gear 41 respectively with this two dorsal column 12 on tooth row 16 engagement; Again, nearly left end place is installed with a worm gear 42 in addition on the hinged arm 40;
One motor unit 50, comprise a motor 51, be arranged on this seat board 23 of left side elevating bracket 20, be available for users to control its rotating (annotating: do not draw switch, distribution and power line etc. among the figure), motor 51 front ends link the gear-box 52 of a work times power deceleration usefulness, gear-box 52 front end levels protrude out a force-output shaft 53 vertical with this hinged arm 40, and these force-output shaft 53 tail ends set firmly a worm screw 54, are these worm gear 42 bottom sides that are engaged on the hinged arm 40.
By said structure, when user's desire is adjusted height of table top, only need starter 51 forward or reverse, mat worm screw 54 1 worm gears 42 mechanisms order about this hinged arm 40 original places rotation, make that hinged arm 40 mat gears 41 1 tooth rows 16 mechanisms keep flatly rising or descending, and force elevating bracket 20 and table 30 upper and lower displacement in the lump, get final product the laborsaving height of table top of adjusting easily, its convenience meets the demand of part physical disabilities or injury especially, except need not exerting all one's strength, such as looking like the wheelchair person the time with regard to the table prelocalization, it is forward in order to wheelchair to wish that table raises, again table is reduced to suitable height after in place, and the electric up-down mode that the utility model provides just can satisfy this kind demand.The user in addition,, non-ly is interim, so can be adjusted to desktop the most suitable individual's height because gear 41 can terminate in arbitrary position on the tooth row 16 surely.
Before take off and implement in the structure, motor 51 is to be arranged at a wherein elevating bracket 20 inboards, however the utility model also can be fixed in motor table bottom surface (annotate: the worm gear on the hinged arm must be located at the corresponding position).Moreover worm screw 54 on motor 51 force-output shafts 53 and the worm gear 42 on the hinged arm 40 can be exchanged mutually, do not influence the utility model function.Additional disclosure is because worm screw-Worm gear mechanism also can the interlock fastening when stopping, so table 30 is positioned can't sink behind the predetermined altitude.But worm screw and worm gear are not must be located at respectively on motor force-output shaft and the hinged arm, and for example the force-output shaft of motor can be set as parallelly with hinged arm, and directly the mat gears engaged turns this hinged arm, and worm screw-worm gear then is installed in the gear-box of making times power deceleration usefulness.
