Between clutch cover 6 and rotating shaft 3 and shaft seat 35, be provided with clutch, this mechanism comprises the round key 36 that is arranged on the clutch cover 6, be arranged on the rotating shaft keyway 38 in the rotating shaft 3 and be arranged on axle bed keyway 39 on the shaft seat 35, when opening 90 degree with interior position, round key 36 on the clutch cover 6 cooperates with axle bed keyway 39 on the shaft seat 35, when opening the above position of 90 degree, the round key 36 on the clutch cover 6 cooperates with rotating shaft keyway 38 in the rotating shaft 3.
Be provided with hydraulic damping device in the axle sleeve of described hinge 21 down, this device comprises piston 22, sealing ring 23, pad 24, one way valve 34, bottom end cover 27, speed adjusting gear, one way valve 34 is fixed on the piston 22, bottom end cover 27 is by sealing ring 25,26 fixedly connected with following hinge 21, speed adjusting gear is arranged on the bottom end cover 27, piston 22 is by sealing ring 23 and following hinge 21 sealings, piston 22 cooperates by the external spiral gear of internal helical gear with rotating shaft 3 lower ends, piston 22 cooperates with spline tooth on the following hinge 21 by external spline teeth, make piston 22 axially straight line move.
Described speed adjusting gear comprises damping regulating rod 28, adjustment seat 30 and set screw 31, set screw 31 is arranged on the bottom end cover 27, set screw 31 is by sealing ring 32 and bottom end cover 27 sealings, bottom end cover 27 has been provided with the jump ring 33 of position-limiting action, adjustment seat 30 cooperates with the interior hexagonal of bottom end cover 27 by outer-hexagonal on it, adjustment seat 30 and set screw 31 threaded engagement, adjustment seat 30 can only be moved axially along bottom end cover 27, damping regulating rod 28 is connected adjustment seat 30, damping regulating rod 28 is for pyramidal structure and be arranged in the adjustment hole of one way valve 34, regulates gap between damping regulating rod 28 and the adjustment hole by damping regulating rod 28.
Its structure such as Fig. 1 and shown in Figure 5 during the utility model closed condition, the round key 36 on the clutch cover 6 cooperates with axle bed keyway 39 on the shaft seat 35, and clutch cover 6 is combined into one with shaft seat 35.When rotating upper hinge 2 when opening, because shaft seat 35 fixedlys connected with play hinge 21, so shaft seat 35 and clutch cover 6 do not rotate, and rotating shaft 3 is rotated under the drive of upper end cover 1, and drive torsion spring 4 rotations beginning energy storage; Meanwhile, rotating shaft 3 moves down by external spiral gear driven piston 22 again, make piston 22 two ends produce pressure reduction, one way valve pearl 29 on the one way valve 34 is by jack-up, thereby open one way valve 34, as shown in Figure 4, hydraulic oil flows fast from bottom to top by one way valve 34, and hydraulic oil does not produce any resistance.When the angle to 90 of opening is spent, as shown in Figure 6, separate and combine from the axle bed keyway 39 of shaft seat 35 at the round key 36 on the clutch cover 6 under torsion spring 4 twisting forces with rotating shaft keyway 38 in the rotating shaft 3, clutch cover 6 is combined into one with rotating shaft 3, torsion spring 4 is finished energy storage, this moment, clutch cover 6, torsion spring 4 rotated with rotating shaft 3 and upper hinge 2 axle bed 35 rooms that rotate, and piston 22 continues to move down under the external spiral gear driven of rotating shaft 3.When continuing from 90 degree when 180 degree are opened, clutch cover 6, torsion spring 4 rotate with rotating shaft 3 and upper hinge 2 axle bed 35 rooms of continuing to rotate, and till the end face of bottom end cover 27 is pushed up in piston 22 bottoms, as shown in Figure 7, thereby finish unlatching work.
When hinge at 180 degree between 90 degree when closing, clutch cover 6, torsion spring 4 rotate with rotating shaft 3 and upper hinge 2 axle bed 35 rooms that rotate, meanwhile, rotating shaft 3 moves up by external spiral gear driven piston 22 again, as shown in Figure 3, makes piston 22 two ends produce pressure reduction, one way valve pearl 29 on the one way valve 34 is closed, hydraulic oil can only be discharged from the top down by the gap between damping regulating rod 28 and one way valve 34 adjustment holes, and hydraulic oil produces closes resistance, thus the purpose that realization is steadily closed.When closing less than 90 degree positions, round key 36 on the clutch cover 6 combines from rotating shaft keyway 38 separation of rotating shaft 3 and with the axle bed keyway 39 of shaft seat 35 under torsion spring 4 return force functions, clutch cover 6 no longer rotates with rotating shaft 3, and be combined into one with shaft seat 35, torsion spring 4 discharges energy storage and drives upper hinge 2 revolutions by rotating shaft 3, meanwhile, rotating shaft 3 continues to move up by external spiral gear driven piston 22, hydraulic oil is discharged from the top down by the gap between damping regulating rod 28 and one way valve 34 adjustment holes, the hydraulic oil generation is closed resistance and is realized steadily closing, up to piston 22 end faces run into axle sleeve 20 end faces or door on the fastening position till, thereby finish the work that automatic steady is closed.
The speed of closing velocity is realized by speed adjusting gear, when closing velocity is too fast, rotation set screw 31 drives adjustment seats 30, damping regulating rod 28 straight lines move up, because damping regulating rod 28 is a pyramidal structure, therefore the gap between damping regulating rod 28 and one way valve 34 adjustment holes dwindles, the flow that hydraulic oil is discharged from the top down reduces, and the resistance when closing increases thereupon, thereby realizes transferring the purpose of slow closing velocity.When closing velocity was too slow, its principle was opposite with the above, no longer repeats at this.
