Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
The utility model takes full advantage of four-bar linkage " dead point " characteristic, designs cleverly a kind of novel two pose locking mechanisms.This mechanism is equivalent to a two-stage four-bar mechanism, and because every grade of clamp mechanism all has " dead point " pose, two-stage four-bar mechanism has two " dead point " poses so, so just formed two pose locking mechanisms.
As shown in the figure: in the utility model mechanism, first connecting rod mechanism comprises pedestal 1, first connecting rod 2, second connecting rod 3, third connecting rod 4, the first rotating shaft 9, the second rotating shaft 10, the three rotating shaft 11, the four rotating shafts 12; Described 1 one-tenth M shape of pedestal, the bottom of pedestal 1 is provided with the first rotating shaft 9, and a summit of pedestal 1 is provided with the second rotating shaft 10, and one end of first connecting rod 2 is hinged with pedestal 1 by the second rotating shaft 10; In the shaft of first connecting rod 2, be provided with the 3rd rotating shaft 11, one end of second connecting rod 3 is hinged with first connecting rod 2 by the 3rd rotating shaft 11; The other end of second connecting rod 3 is provided with the 4th rotating shaft 12, and one end of third connecting rod 4 is hinged with second connecting rod 3 by the 4th rotating shaft 12, and the other end of third connecting rod 4 is hinged with pedestal 1 by the first rotating shaft 9.
Second connecting rod mechanism comprises the 4th connecting rod 5, the five connecting rods 6; The 4th connecting rod 5, driver 7, drives pedestal 8, the five rotating shaft 13, the six rotating shafts 14; The 5th described connecting rod 6 forming V-shapes, the summit of V-arrangement the 5th connecting rod 6 is hinged with another summit of M shape pedestal 1 by the 6th rotating shaft 14, V-arrangement the 5th connecting rod 6 has one end of 2 leg points, the 4th connecting rod 5 point articulated with one of them leg by the 5th rotating shaft 13, the other end of the 4th connecting rod 5 and the 4th rotating shaft 12 are hinged, V-arrangement the 5th connecting rod 6 another leg points are connected with the drive division of driver 7, and driver 7 is connected with driving pedestal 8.
Release mechanism is made up of driver 7 and V-arrangement the 5th connecting rod 6, drives V-arrangement the 5th connecting rod 6 to move drive other link motions to form locking attitude and release attitude by driver 7.
Connecting rod 2,3,4 and pedestal 1 have formed I level clamp mechanism (as shown in Figure 2) jointly, and wherein connecting rod 2,3,4 is respectively take-off lever, intermediate bar, the driving lever of this clamp mechanism.The rotating shaft that driving lever 4 is positioned on pedestal 1 is axle 9, and the rotating shaft that take-off lever 2 is positioned on pedestal 1 is axle 10, and take-off lever 2 is axle 11 with the public rotating shaft of intermediate bar 3, and driving lever 4 is axle 12 with the public rotating shaft of intermediate bar 3, and antenna even load is fixed on take-off lever 2.Also be the axle center of axle 9,11 and 12 while being positioned at same straight line when this clamp mechanism is positioned at pose shown in Fig. 5, it,, in " dead point " pose, is in the lock state for the load being fixed on take-off lever 2.
Connecting rod 4,5,6 and pedestal 1 have formed II level clamp mechanism (as shown in Figure 4) jointly, and wherein connecting rod 4,5,6 is respectively take-off lever, intermediate bar, the driving lever of this clamp mechanism.The rotating shaft that driving lever 6 is positioned on pedestal 1 is axle 14, and driving lever 6 is axle 13 with the public rotating shaft of intermediate bar 5, and take-off lever 4 is still axle 12 with the public rotating shaft of intermediate bar 5.Also be the axle center of axle 12,13 and 14 while being positioned at same straight line when this clamp mechanism is positioned at pose shown in Fig. 7, it is in the lock state for its take-off lever 4 in " dead point " pose.Because connecting rod 4 is also the driving lever of I level clamp mechanism simultaneously, in the time that connecting rod 4 is in the lock state, the output connecting rod 2 of I level clamp mechanism and the load being connected with it are also in the lock state so.
Between driving element 7 and pedestal 8 and connecting rod 6, be all connected with the form of bearing pin, formed the tripper of above-mentioned two-stage four-bar mechanism.Driving element 7 can adopt hydraulic cylinder or electric cylinder, carrys out drivening rod 6 rotate around axle 14 by the length of change cylinder, makes mechanism move to another locking pose from one of them locking pose.
Fig. 6 and the application example that Figure 7 shows that the utility model mechanism falls in perpendicular system at certain radar back of the body feedback antenna.Wherein, Figure 8 shows that " dead point " corresponding locking pose of I level clamp mechanism, the corresponding travel position of back of the body feedback antenna; Figure 9 shows that " dead point " corresponding locking pose of II level clamp mechanism, the corresponding operating state of back of the body feedback antenna.When mechanism is in the time locking pose for these two, offset by the rigidity of locking mechanism self completely from outside load force or loading moment, be also that driving element bears without tripper.
When engineering design, by changing the physical dimension parameter of connecting rod 2,3,4,5,6, can adjust the locking pose of this mechanism.
