The specific embodiment
As shown in Figure 1 and Figure 2, the damping crane that the utility model preferred embodiment proposes, comprise: two parallelogram lindages that be arranged in parallel of cover, linking into an integrated entity by upper width connecting rod 9 and lower width connecting rod 8 between the side link of two cover parallelogram lindages consists of a crane.Lower width connecting rod 8 and upper width connecting rod 9 are the adjustable-width connecting rod, and it can be according to empty size Adjustment width in the table top.Two side links 12,13 of every cover parallelogram lindage are all hinged with a fixed bin 10, the hinged end of the first side link 13 in two side links and fixed bin is to downward-extension, the extension is provided with noise reduction wheel 1, and the wheel shaft of this noise reduction wheel 1 passes the recessed deep-slotted chip breaker be located on the fixed bin 10 and is connected with servomechanism-power assistant spring 2 on being installed in fixed bin 10.In order to bear heavier furniture table-board, in the present embodiment, be provided with a rotary axle box 7 above the second side link 12 in two side links and fixed bin 10 pin joints, this rotary axle box passes the epirelief deep-slotted chip breaker of being located on the fixed bin 10; One reset connecting rod 5 and a reduction torsion spring 6 is hinged on the fixed bin 10, when rotary axle box 7 moves downward along the epirelief deep-slotted chip breaker, can compress the upper end of the described connecting rod 5 that resets, and the lower end of the connecting rod 5 that resets is connected with an oil damping mechanism 4 on being installed in fixed bin 10.As shown in Figure 6, servomechanism also can adopt power-assisted air spring 24.
Such as Fig. 2, shown in Figure 3, according to mesa dimensions, can select the upper and lower width connecting rod 8,9 of different length, with screw 14 itself and two the cover parallelogram lindages side link 12,13 corresponding coupling together.The fixed bin 10 of side link lower end, servomechanism and damping mechanism is built-in, make appearance seem succinct.With screw 15 connecting rod 11 of the present utility model and tea table panel or desk panel 20 are coupled together simultaneously.Be about to the utility model and be used for multi-functional furniture.
With reference to Fig. 1 and Fig. 3, when imposing the active force that a little presses for panel 20, panel can accelerate to descend by its gravity, but drop to certain position (when the second side link 12 forwards 45 degree to, be the upper end that rotary axle box 7 compresses the connecting rod 5 that resets) time, power assistant spring 2 is stretched, and counter plate descends and produces resistance.In addition, oil damping mechanism 4 is stretched and also can produces resistance (not producing resistance during compression).Simultaneously torsion spring 6 distortion also will produce resistance.Several resistance combined effects will cushion the impulsive force of panel decline effectively.When imposing the power that a little lifts panel, under the effect of power assistant spring 2 and torsion spring 6 reset forces, panel can rise easily.Noise reduction wheel 1(noise reduction wheel 3) make of plastic cement, its effect mainly is to eliminate the sound that spring and connecting axle friction are sent in the process that the damping crane uses, and pollution abates the noise.Open arc groove on the fixed bin 10, the angle of connecting rod is limited, be unlikely to open angle excessive, make the table top disequilibrium.Synchronously stable when the utility model can make the crane lifting, noise is little, and operation is light, and profile is succinctly attractive in appearance.
As shown in Figure 4, the second damping mechanism that the utility model uses is provided with a rotary axle box 7 above the second side link 12 in two side links and fixed bin 10 pin joints, and this rotary axle box passes the epirelief deep-slotted chip breaker of being located on the fixed bin 10; One reset connecting rod 20 and a reduction torsion spring is hinged on the fixed bin 10, when rotary axle box 7 moves downward along the epirelief deep-slotted chip breaker, can compress the upper end of the described connecting rod 20 that resets, and the bottom of the connecting rod 20 that resets is connected with a damping due to rotation mechanism 21 on being installed in fixed bin 10.
As shown in Figure 5, the third damping mechanism that the utility model uses is provided with a rotary axle box 7 above the second side link 12 in two side links and fixed bin 10 pin joints, and this rotary axle box passes the epirelief deep-slotted chip breaker of being located on the fixed bin 10; One damping pinion 22 of these rotary axle box 7 terminations and the damping gear wheel 23 of being located on described the second side link 12 and fixed bin 10 jointed shafts consist of the gear damping mechanisms.
Only in order to illustrate structure of the present utility model, those of ordinary skill in the art can make multiple variation to above specific embodiment under design of the present utility model, and these distortion and variation include within protection domain of the present utility model.
