Wheel case 23 and cam shaft 22 built-up section, make the spacing ring 222 of cam shaft 22 hold out against the lower end of packing ring thread 282, thus
Cam shaft 22 is fixed on and determines to tend to upper end position inside hinge axle sleeve 211；Lower capping packing ring 25, adjusting nut 26 successively from
The lower end axis hole determining hinge axle sleeve 211 is put into, and spring 24 is against between cam sleeve 23 and lower capping packing ring 25, finally by lower capping
The 27 lower end axis holes sealing lower jaw 21, the lower embedding post of capping 271 embeds in adjustment hole 261 and through hole 251, makes lower capping packing ring 25
Fix with the top axial position of the lower embedding post of capping 271；Adjusting nut 26 is fixed at the regulation determining hinge axle sleeve 211 inside lower end
Nut is spirally connected at ring 2113, and the most fixing, rotating adjusting nut 26 makes it move axially, thus promotes lower capping
Packing ring 25 axially-movable, thus extruding or release spring 24, the elastic force that regulation spring 24 is initial.
As shown in Fig. 6, Fig. 7, Fig. 8, Fig. 9, the bottom of this utility model cam shaft 22 is provided with the first grooved rail 223, second
Grooved rail 224, the first traveller 232 and the second traveller 233 move respectively in the first grooved rail 223 and the second grooved rail 224；First grooved rail
223 is the track that shape is consistent with the second grooved rail 224, is respectively equipped with the first skewed slot rail 2231 and the first flat grooved rail 2232, second
Skewed slot rail 2241 and the second flat grooved rail 2242；First traveller 232 and the second traveller 233 are the most respectively from the first skewed slot rail 2231
Gradient motion, the first traveller are done to the first flat grooved rail 2232 and the second flat grooved rail 2242 in the upper end of upper end and the second skewed slot rail 2241
232 arrive the first flat grooved rail 2232 and the second flat grooved rail 2242 with the second traveller 233 simultaneously and do thereon as parallel motion,
Gradient motion that the first traveller 232 in cam sleeve 23 and the second traveller 233 are done and horizontal movement Complete Synchronization.Close door state
Under, traveller is positioned at the top of gradient grooved rail, and when dynamic circuit connector page 11 outside half-twist, reversed column moves downward from the top of skewed slot rail
And arriving at when rising as high as the banks (lower end of gradient grooved rail), cam shaft 22 half-twist, due to traveller, to move downward i.e. cam sleeve 23 downward
Motion certain distance compression spring 24, spring 24 has the active force that reverse push moving cam set 23 moves upward, i.e. traveller tool
There is the active force of end motion from the down fold rail of skewed slot rail lower end；Owing to reversed column does upper and lower axially-movable relative to determining hinge 21,
Cam sleeve also does same motion；When release is to the external force of dynamic circuit connector page 11, cam sleeve 23 is promoted by spring 24 and moves upward, cam
Rotating shaft 22 reversely rotates, and dynamic circuit connector hinge 11 is closed automatically；When dynamic circuit connector hinge 11 continues rotating Vortex more than 90 °, the first traveller
232 and second after traveller 233 respectively enters the first flat grooved rail 2232 and the second flat grooved rail 2242, the power of spring 24 suffered by two travellers
Being offset by parallel grooved rail, traveller is free parallel rotation in parallel grooved rail, and slewing area is 90 °.Therefore, door can realize 90 °-
Arbitrfary point hovering in the range of 180 ° of open angles, until door opening state corotating 180 ° completely.
Additionally, door has dividing of left and right opening door mode, Fig. 6, Fig. 7 are left and right two kinds of camshafts, and direction of rotation is contrary, respectively
For left and right different door-opening mode, i.e. it is arranged on the left or right limit of door.Fig. 6 uses on right hinge, and Fig. 7 uses on a left side
On hinge.
