Fig. 2 is the adjustable link supports device of a utility model plan view;
Fig. 3 is the adjustable link supports device of a utility model sectional view;
Fig. 4 moves downward phase diagram for the adjustable link supports device of the utility model;
Fig. 5 is the phase diagram that moves upward of the adjustable link supports device of the utility model.
Embodiment
With embodiment the utility model is described in further detail with reference to the accompanying drawings below:
As Fig. 1, Fig. 2 and shown in Figure 3, the adjustable link supports device of the utility model comprises rocking arm contiguous block 1; rocking arm supporting post 9 and two ends and rocking arm contiguous block 1; two right connecting rods 5 that rocking arm supporting post 9 flexibly connects; two left connecting rods 6 and air spring 7; and two air spring rotating shafts 8 and four connecting rod rotating shafts 10; rocking arm contiguous block 1 is provided with the balance regulator of regulating air spring 7 precompressions; balance regulator comprises regulates double-screw bolt 3; adjusting slider 4; adjusting slider 4 flexibly connects with air spring 7; lower end of adjusting slider 4 is provided with tapped hole; adjusting slider 4 is inserted in the through hole of rocking arm contiguous block 1, regulates double-screw bolt 3 screws in adjusting slider 4 from the lower end of through hole tapped hole.On adjusting double-screw bolt 3, circumferential groove is set, two positioning holes that the position is corresponding with described circumferential groove are set on rocking arm contiguous block 1, undertaken spacing by the 2 pairs of balance regulators of position-limitting pin that pass circumferential groove and positioning hole.
At corresponding position-limitting pin 2 places one circumferential groove is arranged owing to regulate double- screw bolt 3,2 pairs of adjustings of position-limitting pin double-screw bolt 3 has spacing up and down, can be rotated by interior hex tool but regulate double-screw bolt 3.The double-screw bolt screw thread is dextrorotation, when double-screw bolt is regulated in clockwise direction rotation, regulate double-screw bolt since the restriction of position-limitting pin 2 can not on move, so, can spur adjusting slider 4 and move down along with the screwing of screw thread.Otherwise, when the double-screw bolt of rotation adjusting counterclockwise, can promote adjusting slider 4 and up move, thus the angle and the length of fine setting air spring 7, thus the stress balance of regulating device.
Another mode of execution of the adjustable link supports device of the utility model is that balance regulator is arranged on the rocking arm supporting post 9, balance regulator comprises regulates double-screw bolt, adjusting slider, adjusting slider and air spring flexibly connect, the lower end of adjusting slider is provided with tapped hole, adjusting slider is inserted in the through hole of rocking arm supporting post 9, regulates double-screw bolt screws in adjusting slider from the lower end of through hole tapped hole.On the adjusting double-screw bolt, circumferential groove is set, two positioning holes that the position is corresponding with described circumferential groove are set on rocking arm supporting post 9, carry out spacing to balance regulator by the position-limitting pin that passes circumferential groove and positioning hole.
To regulate double-screw bolt 3 earlier when assembling adjustable link supports device and put into rocking arm contiguous block 1 through hole, regulate correct position, insert position-limitting pin 2.Adjusting slider 4 is inserted in rocking arm contiguous block 1 through hole, and double-screw bolt 3 is regulated in rotation, screws by screw thread and moves adjusting slider 4 to suitable position.Penetrate in adjusting slider 4 and air spring 7 holes and tighten with threaded air spring rotating shaft 10.With another root air spring rotating shaft 10 that the other end and the rocking arm supporting post 9 of air spring 7 is fixing equally then.On four holes of rocking arm contiguous block 1 and rocking arm supporting post 9, put into four connecting rod rotating shafts 10, earlier two left connecting rods 6 are inserted in connecting rod rotating shaft 10 left sides, again two right connecting rods 5 are inserted in the rotating shaft on right side.
As shown in Figure 4 and Figure 5, select because the power value characteristic of air spring is calculated according to supported object, therefore, adjustable link supports device is in a stress balance state.Upper end limit position in adjustable link supports device motion, and any position between the limit position of lower end, because the stress of balance and the existence of air spring and mechanism's surface friction drag, as long as press with have gentle hands, adjustable link supports device promptly can be turned to the arbitrary position, and still can rest on this place after unclamping arm.
Those skilled in the art do not break away from essence of the present utility model and spirit, can there be the various deformation scheme to realize the utility model, the above only is the preferable feasible embodiment of the utility model, be not so limit to interest field of the present utility model, the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, and all is contained within the interest field of the present utility model.
