On the basis of technique scheme, be provided with at the middle hypomere of the Inner of piston bush 14 wall and close a gas pressure relief slot 23.The effect of closing a gas pressure relief slot is: when door closes closed front 5 to 10 degree, utilize the gas pressure relief slot oil return, make the hydraulic oil pressure release in the pressurized oil pocket, the spiral chute (0～90 degree cam path 303) that sees through the piston shaft slides with the piston boit pin 15 that two ends are through symmetrical two cinclides in piston bush top, make the screw of piston energy rapid axial band, the slide-matching groove that sees through piston and axle core makes the axle core do the rapid spiral motion, can enter smoothly lock thereby the upper hinge of drive makes an energy close the door fast at closed front 5 to 10 degree.Close the middle hypomere that a gas pressure relief slot is arranged on the Inner wall of piston bush 14, hydraulic oil can when closing in front of the door 5 to 10 degree position, be passed through from the inwall of piston bush 14 and the gap between the piston oil seal 17.
On the basis of technique scheme, be provided with magnetite 22 in the lower capping 20.The effect of magnetite is: utilize the iron filings of magnetic-adsorption hinge in production and use procedure, make hydraulic oil Bao Chi Cheongju clean, hinge can smoothly be moved.As shown in Figure 1, magnetite 22 can be arranged in the blind hole of low head 20 inner faces, and magnetite end face and low head inner face keep certain distance to prevent that the iron filings of absorption are brought back in the working oil chamber.Described blind hole position is without specific (special) requirements.
On the basis of technique scheme, the external surface that lower capping 20 is exposed to outside overcoat 5 lower ends is provided with the annular knurl groove.
During use, as shown in Figure 4, Multifunctional hinge mandrel of the present invention can be socketed in copper, iron, aluminium, in the endoporus of the hinge of the materials such as stainless steel, specifically: overcoat 5 is placed in, lower jaw 401, in 402 the endoporus, and the upper part of overcoat 5 can freely be rotated in the endoporus of upper hinge 401, axle core 1 is provided with the end that connects plane 202 and exposes, exposed parts is sleeved in the endoporus of hinge fixed cover 403 and by screw 404 and is connected with upper hinge fixed cover 403 compressions, the endoporus of described upper hinge fixed cover 403 is provided with the plane adaptive with being connected plane 202, the two can be rotated synchronously, the lower end of overcoat 5 fixedly is threaded onto in the endoporus of lower jaw 402, and by the annular knurl groove anti-skidding that lower capping 20 external surfaces arrange, just torsion can be delivered to axle core 1 when opening the door.
The user can stretch into by the speed governing wick 18 of spiral way accommodation zone vertebra degree shank the insertion amount of piston 13 inner chambers, the gap length of regulating shank and speed governing valve opening (its essence is an oil-through hole) is controlled the flow of the hydraulic oil in pressurized oil pocket and the shoe cream room: hydraulic oil flows to pressurized oil pocket 25 by one way valve 24 from shoe cream room when opening the door, hydraulic oil flows to shoe cream room by the speed governing valve opening from the pressurized oil pocket at closing time, and 5 to 10 hydraulic oil when spending flow to shoe cream room by gas pressure relief slot from the pressurized oil pocket when closing the door.Thereby axial zone screw speed that can regulating piston 13 realizes adjusting a speed of closing.
The user can regulate vertical voltage regulation screw 2 amount of feeding by spiral way, promotes horizontal voltage regulation screw 11 takes this to adjust stage clip 12 do axially-movable top pressure amount.Axial compression suffered when the darker stage clip 12 of vertical voltage regulation screw 2 screw-ins opens the door is larger, and just larger then door closing force is just larger to borrow at closing time the energy of putting.
The present invention has adopted unique piston helicla flute (cam path) Curve Design, helicla flute 0 degree to 90 degree of piston shaft are designed to skewed slot along axle body, upper hinge 401 couple axle cores rotate when opening the door, piston boit pin 15 effects that see through 0～90 degree cam path and be fixed on the piston bush 14 are lower, make piston 13 see through slide-matching groove with axle core 1 will rotatablely move become the rotating band upward axis to motion, compress stage clip 12 and do accumulation of energy.
When spending less than 90 when closing the door, piston 13 sees through slide-matching groove under the promotion of stage clip 12 and axle core generation Axisal movement moves, at 0～90 degree cam path be fixed under piston boit pin 15 effect on the piston bush 14, the sliding force of piston 13 is converted to revolving force and the rotation of couple axle core of piston.
In the positions of switch gate 90 degree to 180 degree, the piston boit cam line of rabbet joint with it at grade, so when door during in this angular turn the decrement of stage clip 12 do not change, this moment, horizontal voltage regulation screw 11 was in the compression energy storage state.So door can stop arbitrarily at 90 degree to 180 degree.Open arbitrarily a gap slot door at this angular range inner spiral groove and just can stop in the relevant position, can play the effect that door stops.
The present invention is by making the axle core that is placed in upper hinge and the overcoat 5 that is tightly placed in lower jaw be in the rolling connection status with needle bearing 4 and several the steel balls 9 that place axle core 1 stage casing.Frictional force when reducing switch gate reduces noise, reduces wearing and tearing mandrel can long-term safety steadily be worked effectively.
The present invention in actual use course of work is as follows:
The helicla flute of piston shaft is to be parallel to rising as high as the banks of end face when open angle is spent to 180 greater than 90 degree, so piston does not have axially-movable when this section angular turn, the compression spring pressured state does not change, and becomes energy storage state.Hydraulic oil in shoe cream room and the pressurized oil pocket does not flow mutually.So door can be parked in arbitrary position of 90 to 180 degree.
The piston spring that is under pressure releases energy and makes axial-movement downwards when spending less than 90 when closing the door, see through the spiral chute of piston shaft 0 to 90 degree and pass across helicla flute, two ends are enclosed within the interior piston boit pin 15 slip effects of two the symmetrical pin holes in piston bush 14 shaft tops, make piston along 0 to 90 degree spiral chute rotation when downward axial-movement, the piston rotation sees through 1 rotation of slide-matching groove band moving axis core, the rotation of axle core sees through upper hinge fixed cover 403 and drives upper page or leaf 401 rotations, realizes automatic door-closing.
When making axial-movement downwards, piston promotes the hydraulic oil in the pressurized oil pocket, make the hydraulic oil in the pressurized oil pocket slowly flow to shoe cream room from the gap between the vertebra degree shank of speed governing valve opening and speed governing wick upper end, thereby the axle of piston is closed the door slowly to slow realization of the moving Minus of fortune.
The user can be by the insertion amount of spiral way adjustment with the speed governing wick 18 of tapering shank, the gap length that changes between tapering shank and the speed governing valve opening was controlled oil mass, it is less with the gap of speed governing valve opening that the speed governing wick inserts darker then tapering shank, and to cross oil just less to the mistake oil mass of shoe cream room for the pressurized oil pocket at closing time.The speed of then closing the door is slower, otherwise self-closing door is just faster, thereby realizes closing an adjustment of speed speed.Adjust voltage regulation screw 2 by spiral way, the insertion amount of adjusting voltage regulation screw see through cross in the pressure regulation pin of axle core to compression spring unload the pressure adjustment, it is larger that the darker then compression spring of the insertion amount of voltage regulation screw unloads pressure, the power that is applied to self-closing door is larger.Otherwise then reduce the just very convenient size of adjusting door closing power of such user.
The content that is not described in detail in this manual belongs to the known prior art of this area professional and technical personnel.
