'When the oil pressure is greater than the elastic member (10) When the elastic force of the third steel ball 84 is reversed, the third anti-reverse steel ball 84 is pushed to allow the hydraulic oil to flow from the left side of the piston 46 to the right side of the piston 46 via the third different diameter hole 822, as shown in the sixth figure. Show. The above detailed structure of the heaven and earth hinge 1G of the present invention will be described below with reference to the use process and features of the present invention. When the door panel has an opening action, the door panel will rotate the rotating shaft 36, and the cam plate 362 connected to the rotating shaft 36 will push one of the rotating wheels 34 on the left side of the cam plate 362 to drive the length of the two pressing plates 32 along the base 2 The direction moves to the left'. The two pistons 46 of the damping unit 40 are gradually moved to the left with the two pressure plates 32. As shown in the second figure, the hydraulic oil at this time will flow through the first guide from the oil storage space 21 located on the left side of the piston. The oil hole 25 to the second section 8 of the oil guiding passage 22 201239184 223' will then push the second non-reverse steel ball % of the check valve 70 into the second reducing hole 722 of the check valve 70, and then from the stop The second valve hole π# of the valve 7〇 flows through the second oil guiding hole 26 to the oil storage space X2丨 located on the right side of the piston 46, and when the piston 46 continuously moves to the left to block the first oil guiding hole, the false second The back resistance adjusting valve 60 is in a locked state. As shown in the fourth figure, the plug 46 will not flow through the oil passage in the oil storage space 21 through the first stage 22 of the oil guiding passage. The second section 223 stops moving, and the door panel stops. If the __ pushes the door panel at this time, the third is pressed 8 The reverse steel ball 84 is pushed away by excessive oil pressure. As shown in the sixth figure, the hydraulic oil can flow from the left side of the piston 46 to the right side of the piston 46 via the fourth differential bore 822 which is 8 inches wide. In order to achieve the effect of forced oil loss, the door panel will open until about 6 〇 ± 6 degrees will stop; otherwise, when the piston 46 moves to the left to block the first oil guiding hole 25, if the back resistance is adjusted ^ 6〇 is the released state. As shown in the fifth figure, the hydraulic oil will enter the first section 221 of the oil guiding passage 22 from the oil storage space 21 on the left side of the piston, and through the back-resistance δ circumference valve 6 〇 The loose gap between the second adjustment holes 24 flows to the second section 223 of the passage 22, and then the second check valve 74 of the check valve % is pushed open to flow into the second of the check valve 7 The different diameter hole is cut, and then flows from the second valve hole 724 of the check valve 7 through the second oil guiding hole 26 to the oil storage space 2 located on the right side of the piston 卜 as shown in the fifth figure. The aspect is the force received when the door panel is _; when Xiao loses, it should move toward the off and move. If the flow regulating valve 50a is locked at this time, the door panel ^ will not move,' as shown in the eighth figure. If the damping of the flow regulating valve 5 is released, the piston 46 of the damping 40 will be moved to the right by the returning force of the elastic member 44 from 201239184. The piston 46 of the damping unit 40 blocks the first oil guiding hole 25 and the fourth. The oil guiding hole 28, as shown in the seventh figure, the hydraulic oil at this time flows from the oil storage space 21 located on the right side of the piston 46 through the third oil guiding hole 27 and the flow regulating valve 50 a and the first adjusting hole 23 The second gap 223 of the oil guiding passage 22 is separated by a loose gap between a and then a portion of the hydraulic oil may flow through the oil guiding passage 22 through a gap loosened between the back resistance adjusting valve 60 and the first s circumferential hole 24 The first section 221 is located in the oil storage space 21 on the left side of the piston 46, and the other part of the hydraulic oil pushes the first of the back resistance adjusting valve 60 - the check ball 64 and flows into the back resistance adjusting valve 60 A different diameter hole 622 flows from the first valve hole 624 of the back resistance adjusting valve 6 through the first section 221 of the oil guiding passage 22 to the oil storage space 21 located on the left side of the piston 46, as shown in FIG. When the door panel is continuously closed, the piston 46 of the damping unit 40 will continue to move to the right to completely block the third oil guiding hole 27' as shown in the tenth figure. If the flow regulating valve 50b is locked at this time, as in the first As shown in the eleventh figure, the door panel will stop moving but has not been completely closed. At this time, the door panel angle is about 15 degrees. If the flow regulating valve 50b is released, as shown in the twelfth figure, the hydraulic oil will be located from the piston 46. The oil storage space 21 on the right side flows through the gap between the second oil guiding hole 26 and the flow regulating valve 50b and the first adjusting hole 23b to the third section 225 of the oil guiding passage 22, at which time the piston 46 of the damping unit 40 The position is to completely block the third oil guiding hole 27, and the fourth oil guiding hole 28 is not completely blocked. Then, a part of the hydraulic oil flows from the fourth oil guiding hole 28 to the oil storage on the left side of the piston 46. The space 21, the other part of the hydraulic oil is from the gap between the flow regulating valve 50a and the first adjusting hole 23 to the second section 223 of the oil guiding passage 22, and then flows from the first oil guiding hole 25 to the piston. 46 left side 10 201239184 oil storage space 2 until the door panel is completely closed. It can be seen from the above description that the heaven and earth hinge lG of the present invention can control the freshness of the door panel according to different adjustments of the squat resistance, and the opening angle of the back-resistance adjusting valve is tight. Since the amount of oil between the back resistance adjusting valve 60 and the second adjusting hole 24 is small, the cushioning force that the door panel is subjected to when it is opened will be larger, and the difference in the opening of the door panel will be smaller, when the back 60 is The locking door opening angle is about 6 〇 6 degrees, and the cushioning force will be large. On the contrary, when the back resistance adjusting valve (9) is locked loose, the back resistance can be adjusted 阙6〇 and the second adjustment. The greater the amount of oil between the holes 24, the less the cushioning force the jaws will receive when they open, and the greater the test of the jaws. Even if the back_full valve 6G is fully locked, the action of the forced gasoline can be performed by the stern valve 8' to effectively prevent the door panel and the heaven and the chain 10 of the present invention from being damaged. g It is worth mentioning that the flow regulating valves 5〇a, 50b are provided for the purpose of two groups. In order to enable the door panel to perform a two-stage closing operation, it is of course also possible to provide a single group flow regulating valve 50a so that the door panel has only one section closed. action.
