Graduating power.Wherein: the crank IV 51 is identical with V 53 structure of crank, be symmetrical arranged, by crank IV 51 with crank II 32 around
Support I 8 rotates, and crank V 53 is driven to rotate around support II 9, realizes that power is transmitted in III 52 horizontal movement of bar.
As shown in Figure 1, shown in Figure 5, the present invention is additionally provided with centering spring mechanism 6, is placed in spatial four-bar mechanism 3 described vertical
Parallel with the longitudinal supporting plate 71 to 71 two sides of support plate, one end and fixing piece 65 are hinged by articulated shaft 62, and by solid
Determine part 65 to be connected on longitudinal supporting plate 71, the other end passes through hinged axis connection Handle axis 31；The effect of centering spring mechanism 6 is
So that mechanism is in stress always, does not swing at random.
The centering spring mechanism 6 includes spring 63, crank VI 61, spring lever 64 and fixing piece 65, the spring lever 64
Upper pocketed springs 63,64 one end of spring lever are fastened on the fixing piece 65 on structural box 7, other end connecting crank VI 61,
Crank VI 61 connects Handle axis 31；Spring is constantly in compressive state in entire motion process；Under completely upper latch mode, spring
63 make all mechanisms be maintained at the position fastened with a bolt；When pull handle 1 start solution door bolt when, crank VI 61 turns to Handle axis 31 and bullet
For the axis of the articulated shaft of 63 both ends of spring connection in same plane, centering spring mechanism, which has reached, crosses center critical state, continues
When rotational handle, spring 63 drives sleeve mechanism movement until reaching solution door bolt position completely.
Wherein: centering spring mechanism 6 and spatial four-bar mechanism 3 are placed in 71 two sides of longitudinal supporting plate, in rotational handle 1
When, door bolt and movement of fastening with a bolt are solved by the elastic force auxiliary of the spring of centering spring mechanism 6.
The control method of present invention door bolt device, comprising the following steps:
As shown in Figure 1, being locking state of the present invention, when needing to solve door bolt, as shown in fig. 6, grasping handle 1, upwards (i.e.
Direction shown in figure) rotation is pulled, overcome the resistance of spring 63, Handle axis 31 is driven to rotate, the drive of Handle axis 31 connects therewith
The spatial four-bar mechanism 5 connect moves, and the crank II 32 for connecting its end is rotated around support I 8, and driven rod I 33 moves to minimum
Point, the bar II 41 of hinged left crank slide block mechanism 4 moves to highest point with II 32 other end of crank, and door bolt 42 is driven to slide along door bolt
43 horizontal movement of slot (being moved to right direction shown in Fig. 1), so that the left side of structural box 7 solves door bolt, process of fastening with a bolt and its phase
Instead.Meanwhile the crank II 32 of spatial four-bar mechanism 3 drives the crank IV 51 of four-bar linkage 4, crank V 53 to rotate, and drives
4 horizontal hunting of four-bar linkage, when bar I 33 moves to minimum point, four-bar linkage 4 is rocked to the right greatest limit,
It drives the crank I 2 of right crank slide block mechanism 4 ' to move to minimum point, so that bar II 41 ' is moved to the leftmost side, thus structural box
7 right side solves door bolt.Process of fastening with a bolt is opposite to that.
The present invention is in compressive state during installation, continues to compress in rotation incipient stage, spring 63, and spring 63 hinders hand
Handle power solution door bolt after rotating to certain angle, has served as when crossing center of the spring 63 of centering spring mechanism 6, spring 63 extends, handle
Power and spring force one are sent to a place under guard door bolt, as shown in fig. 6, fastening the state of device with a bolt or latch when solution door bolt.Process of fastening with a bolt is opposite to that.
