Wherein, rotating buffer C comprises outer wall 1 and is positioned at the rotation switching mechanism of its inside and the buffer gear that is coupled with this rotation switching mechanism; Outer wall 1 comprises the first end section 101, the second end section 102 that is positioned at its two ends, and is positioned at the stage casing 103 in the middle of the section of two ends; Wherein, preferably, the first end section 101 and stage casing 103 are used to hold rotation switching mechanism, and the second end section 102 is used to hold buffer gear; Described stator A one side has outstanding fixed part, be individually fixed in two ends section 101,102, and rotatable lamella B has outstanding fixed part and be fixed in stage casing 103.
The another kind of setting is if that the second end section long enough, buffer gear also can be positioned at the second end section.
Perhaps, the second end Duan Yudi, three end sections merge, and make outer wall 1 only comprise two end sections, and at this moment, stator A is fixed in an end section by a fixed part, and rotatable lamella B also is fixed in other end section by a fixed part.
In a kind of realization of rotating switching mechanism, be included in the first end section 101 and be fixedly connected with gland 24 by steady pin 22, by screw one compressing tablet 25 is arranged near a side of ends at gland 24; Also comprise screw rod 17, one section is passed gland 24 and lock part 171 is set in the end, for example spline or square toes, such setting in order to its can with the lock part at compressing tablet 25 middle parts, spline for example, perhaps a square opening matches; Screw rod 17 another sections have multiple thread 172 and are used to cooperate bull nut 28.The middle part of screw rod 17 also is provided with step 174, is provided with bearing 23 between step 174 and gland 24; The multiple thread section 172 of screw rod 17 is combined with bull nut 28, the outer wall of this bull nut be provided with along nut shaft at least one key 281, this key cooperates the internal keyway that is positioned at stage casing 103; Certainly this set also can be opposite, promptly in the stage casing 103 key is set, and bull nut 28 outer walls is provided with keyway.
The lock part of screw rod 17 can also be provided with regulates mouth, be used for being engaged in rotary screw under the situation of taking off compressing tablet 25 with external tool, thus the initial position of adjusting bull nut.
In second kind of realization of rotating switching mechanism, both in the simple realization, comprised screw rod 17, screw rod 17 parts directly or by a middleware and the first end section 101 are connected, thereby keep it not move relatively with the first end section 101.Another part is by screw thread, and for example multiple thread match with a nut, and this nut matches with the second end section 102 with the structure of keyway by key.
In above-mentioned two kinds of realizations, when rotatable lamella B rotated, it drove stage casing 103 and rotates, and 103 rotation then drives bull nut co-rotation; Simultaneously because the bull nut matches with screw rod 17, and whether screw rod 17 103 or not when rotating in the stage casing, so can be under the effect of the threaded engagement relative screw rod of bull nut 28 17 moves along screw axial.This moment can threaded engagement direction be set to become 90 to spend in becoming big process gradually with rotatable lamella B as stator A, bull nut 28 relative screw rods 17 move to the direction away from screw rod.
Buffer C comprises shell, shell can be the second end section 102, the second end section, 102 ends are combined with cylinder cap 12, are combined with inner cylinder body 2 on the cylinder cap 12, and inner cylinder body stretches into the second end section and props up oil sealing 16 and be used for flowing of hydraulic oil with the intersegmental formation of second end annular gap.
The end of bull nut 28 is connected with piston rod 7 by pin 21, and piston rod passes oil sealing 16 and matches with a piston 8.Piston 8 can move in the space between oil sealing 16 and the cylinder cap 12, is filled with the hydraulic oil of certain volume in this space.
The far-end that stretches into the second end section and the oil sealing of inner cylinder body 2 are gapped, thereby form first oil-recovery tank 3, be provided with first spill port 11 that is arranged in same axial position near the far-end that stretches into the second end section on the inner cylinder body 2, then be provided with second oil-recovery tank 6 between inner cylinder body 2 and cylinder cap 12, this second oil-recovery tank is communicated with space between piston 8 and the cylinder cap 12 by a set screw 14.
Piston 8 is two zones with the space segmentation between oil sealing 16 and the cylinder cap 12, i.e. the L district of the Zone R of close oil sealing 16 and close cylinder cap 12.The inwall matched in clearance of piston 8 and inner cylinder body 2 circumferentially has circular passage 5 at piston side wall, and is being axially arranged with a plurality of oil-through hole H that are connected with passage 5, is provided with the O-ring seal 4 of line footpath less than the passage bore in described circular passage.
Shown in Fig. 2 A, when piston 8 under the drive of piston rod 17, when cylinder cap 1 direction is moved, promptly in the process that door is opened, hydraulic oil not only can flow back to Zone R with gap and first oil-recovery tank, 3 these loops of shell 1 by second oil-recovery tank 6, inner cylinder body 12, because O-ring seal 4 is close to a side of close oil sealing 16 in the circular passages, circular passage 5, oil-through hole H are communicated with L region R district so simultaneously, and hydraulic oil also can directly flow to Zone R by the L district; Can not form resistance, i.e. cushion effect this moment.The size that is opened of door has determined the stroke of piston 8, and the maximum subtended angle position of door should be the position of piston during near cylinder cap.
When piston 8 under the drive of piston rod 17, when the direction of oil sealing 16 is moved, promptly in the process that door is closed: the incipient stage, shown in Fig. 2 B, because O-ring seal 4 can be under the effect of piston, be close to the side of circular passage 5 near cylinder cap, like this, will be oil-through hole H, circular passage 5 and piston and this path sealing of inner cylinder body gap, like this, hydraulic oil just can only pass through first oil-recovery tank 3, first spill port 11, and the L district is flowed back to from Zone R in second oil-recovery tank, 6 these loops, promptly the flow by second backflash 6 determines, thus the buffering of realization.When between piston motion to the first oil-recovery tank 3 to first spill ports 11, shown in Fig. 2 C, promptly first spill port has been in the L district, then the remaining hydraulic oil of Zone R can directly flow into the L district by first spill port 11, thereby the effect of buffering can weaken greatly, piston is on this position the time, and the active force that is applied on the rotatable lamella B can make piston 8 that remaining hydraulic oil is extruded into the L district, thereby piston 8 is pressed close to oil sealing 16 rapidly.
The velocity of rotation of aforementioned bull nut 28 can be designed as with its axially-movable speed and is directly proportional.Like this, promptly can control the rotary speed of nut by the movement velocity of piston in the control buffer, i.e. Men switching speed, and by suitably designing the position of first spill port 11, promptly can determine the door maximum angle of time pass fast, promptly these holes 11 are big more near the then maximum pass angle of returning fast of cylinder cap more.
Simultaneously, under the definite situation in the position of first spill port 11, rotate compressing tablet 25 by adjusting, can regulate the axial location of bull nut 28 equally, thereby the initial distance of the fine setting piston and first spill port 11, thereby further determine the beginning angle that door leaf goes back to the pass fast, for example between 10 to 30 degree.Piston initial position distance first spill port 11 is near more, and then time pass angle is more little fast.
In addition, fuel-flow control screw 14 can also be set at cylinder 12, by adjusting this set screw.The flow velocity of control oil return, the average switching speed of all right control gate.
Buffering hinge of the present invention preferably is used with spring hinge in use, and for example, upper hinge is set to spring hinge, and time hinge is set to cushion hinge; Perhaps, upper and lower hinge is set to spring hinge, and middle hinge is set to cushion hinge.After door was opened like this, the restoring force that door is closed can be provided by spring hinge.
