The utility model 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; When opening the door, going up hinge 401 couple axle cores rotates; See through 0～90 degree cam path be fixed on the piston bush 14 15 effects of piston boit pin down, 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 and produces axially slippage down with the axle core under the promotion of stage clip 12; 0～90 degree cam path be fixed on the piston bush 14 15 effects of piston boit pin down, the revolving force and the couple axle core that the sliding force of piston 13 are converted to piston rotate.
In the position of switch door 90 degree to 180 degree, the piston boit cam line of rabbet joint on one's body 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 energy storage state that compresses.So door can stop arbitrarily at 90 degree to 180 degree.Open a gap slot door arbitrarily at this angular range inner spiral groove and just can stop, can play the effect that door stops in the relevant position.
The utility model is through making axle core that is placed in hinge and the overcoat 5 that tightly is placed in lower jaw be in the rolling connection status with needle bearing 4 and several the steel balls 9 that place a core 1 stage casing.Reduce to open frictional force at closing time, reduce noise, reduce wearing and tearing mandrel can long-term safety steadily be worked effectively.
The utility model course of work in actual use is following:
When open angle is to be parallel to rising as high as the banks of end face greater than the helicla flute of 90 degree piston shaft when 180 spend, so piston does not have axially-movable when this section angular turn, the compression spring pressured state does not change, and becomes the 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 piston boit in two the symmetrical pin holes in piston bush 14 shaft tops and pin under 15 sliding action, make piston when axial-movement downwards along 0 to 90 degree spiral chute rotation, the piston rotation sees through slide-matching groove and drives 1 rotation of axle core; The rotation of axle core sees through last hinge fixed cover 403 and drives upward page or leaf 401 rotations, realizes closing the door automatically.
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, thereby the axially-movable of the piston realization of slowing down is closed the door slowly from the gap between the vertebra degree shank of speed governing valve opening and speed governing wick upper end.
The user can be with the insertion amount of the speed governing wick 18 of tapering shank through the spiral way adjustment; The gap length that changes between tapering shank and the speed governing valve opening was controlled oil mass; It is more little with the gap of speed governing valve opening that the speed governing wick inserts darker then tapering shank, and the pressurized oil pocket is crossed oil to arrive the mistake oil mass of shoe cream room just more little at closing time.The speed of then closing the door is slow more, otherwise self-closing door is just fast more, thereby realizes closing an adjustment of speed speed.Through spiral way adjustment voltage regulation screw 2, the insertion amount of adjustment voltage regulation screw see through cross in the pressure regulation pin of axle core to compression spring unload the pressure adjustment, the insertion amount of voltage regulation screw more deeply then compression spring to unload pressure big more, the power that affacts self-closing door is big more.Otherwise then reduce the size that such user just can easily regulate door closing force.
