Five, embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, positive drive chain of the present invention comprises the right interior connecting plates 2 of many compositions of forming right outside link plate 1, being arranged on outside link plate 1 inboard more, also comprises a plurality of coupling shaft 3, following coupling shafts 4 gone up; Described outside link plate 1, interior connecting plate 2 upper limb bilateral symmetry be provided with identical fillet, lower edge be straight line and parallel with upper limb, left border is vertical with lower edge with right border, outside link plate 1, interior connecting plate 2 upper ends are symmetrically arranged with the identical upper left axis hole 5 of diameter and upper right axis hole 6, lower end bilateral symmetry are provided with two semicircle orifices 7, are provided with lower shaft hole 8 at two semicircle orifices, 7 circle center line connecting mid points; Described outside link plate 1 in couples by the upper left axis hole 5 on it with one pair in upper right axis hole 6 on the connecting plate 2 through last coupling shaft 3 flexible connections, upper right axis hole 6 and the upper left axis hole 6 on another internal connecting plate 2 that outside link plate 1 passes through on it in couples flexibly connect through last coupling shaft 3, and paired outside link plate 1, interior connecting plate 2 pass through coupling shaft 4 connections down through lower shaft hole 8 respectively; Described upward coupling shaft 3, following coupling shaft 4 two ends are provided with fixing device.
After having adopted said structure, paired outside link plate 1 is formed outer box unit, box unit in paired interior connecting plate 2 is formed, outer box unit, interior box unit inside are by last coupling shaft 3, coupling shaft 4 connections down, play a supporting role, guarantee connection stability, thus effectively transmission and load-bearing.The length of last coupling shaft 3, following coupling shaft 4 is identical, is convenient to chain work.By coupling shaft 4 connections down, following coupling shaft 4 is complementary with the semicircle orifice 7 of adjacent interior connecting plate 2 lower ends paired outside link plate 1 through lower shaft hole 8; Paired interior connecting plate 2 connects by coupling shaft under another 4 through lower shaft hole 8, following coupling shaft 4 is complementary with the semicircle orifice 7 of adjacent outside link plate 1 lower end, the diameter of semicircle orifice 7 is complementary with following coupling shaft 4 diameters, and its function is to carry out spacing to outside link plate 1, interior connecting plate 2.Outer box unit, interior box unit are in rotary course, and when rotating to the adjacent cells parallel position, semicircle orifice 7 is meshed with following coupling shaft 4, and blocking unit continues rotation, guarantee the rigidity of transmission.
As shown in Figure 7, one of typical case's application of the present invention is to carry out vertical weight lifting.Horizontal arrangement of the present invention in orbit, track end is provided with short chute that turns to, it is terminal vertical with track, load is preset at above the chute.By ratchet the present invention is applied power, the present invention carries out displacement.When running into when turning to chute, outer box unit, interior box unit rotate successively, and be up when rotating to Vertical direction.Adjacent outer box unit, interior box unit continue rotation successively, and it goes to when parallel with a last unit, and semicircle orifice 7 is meshed with following coupling shaft 4, thus realization end face tight engagement, can positive drive.After the present invention touches load, continue to apply power, thereby load is upwards elected.Oppositely apply power, load steadily can be moved down.
The physical dimension of described inside and outside connecting plate 1,2 is identical, and the spacing between upper left axis hole 5 and the upper right axis hole 6 is identical with spacing between semicircle orifice 7 and the lower shaft hole 8.
Inside and outside connecting plate 1,2 of the present invention can be designed to identical size, can reach the most stable work effect like this, also is convenient to produce and maintenance.Under application circumstances, inside and outside connecting plate 1,2 its length also can be different, but require this moment the spacing between spacing, semicircle orifice 7 and the lower shaft hole 8 between upper left axis hole 5 and the upper right axis hole 6 to match each other.
The described fixing device that goes up coupling shaft 3 and following coupling shaft 4 two ends is a round nut 9.
Adopt round nut to fix, be convenient to chain and turn to,, can add wave washer between round nut 9 and the inside and outside connecting plate 1,2 for strengthening fixed effect along track.
Be provided with lining 10 between described coupling shaft 4 down and the round nut 9; Described round nut 9 outer ends are provided with sliding sleeve 11, and sliding sleeve 11 outer ends are provided with snap ring 12.
Behind the interior connecting plate 2 of round nut 9 lockings, because lining 10 length greater than the thickness of outside link plate 1, are turned round the space that needs thereby assurance outside link plate 1 centers on last coupling shaft 3.The effect of sliding sleeve 11 is when orbital motion of the present invention, reduces friction, plays the effect of protection chain, and snap ring 12 plays fixation.
All there is outside link plate 1 in wantonly two groups of adjacent interior connecting plate 2 outsides.
The present invention can prolong by the quantity of connecting plate 2, outside link plate 1 in increasing, and length reaches one regularly, and the present invention can join end to end, and adopts enclosed work, and its structure, function class are like conventional chains.
The present invention can adopt metallic material to make, and when bearing load is little, also can adopt other materials to make.
The present invention both can enclosed work, but also open type work especially can apply power by substantially horizontal, is implemented in Vertical direction and carries out weight lifting.Its simple in structure, stable performance is widely used, and possesses good market prospects.
