Operating principle of the present utility model:
Spring for accumulating energy body motion process:
When wing was opened, upper shell 1 rotated, and drove energy storage roller 9 and moved in the skewed slot raceway, because the effect of slide rail 13,14.Make major and minor gliding mass 11,12 descending, major-minor spring 15,16 is compressed energy storage simultaneously, and when energy storage roller 9 rotates at gliding mass chock plug inner plane, but upper shell optional position in set angle stops operating.According to the needs that use,, when energy storage roller 9 rolls into detent, just play the corner positioning action at gliding mass chock plug inner plane processing detent.
When wing need be closed automatically, mode by external force makes energy storage roller 9 enter the skewed slot raceway, main spring 15 and auxiliary spring 16 release energy in succession, move on the main gliding mass with energy storage roller 9 and produce twisting resistance, make upper shell 1 rotate the design scheme that has realized multistage relay spring for accumulating energy.On major and minor spring, to there be certain pre-compression force to adjust by voltage regulation screw 18.
Hydraulic damping body running process:
When upper shell rotated, damping roller 26 moved in hollow gliding mass 22 skewed slot raceways, because the effect of slide rail makes gliding mass 22 descending, fluid enters oilhole through oil duct below fuel tap, open fuel tap and enter above the fuel tap.The damping roller leave skewed slot raceway gliding mass when the chock plug inner plane rotates stop descending because return spring 22 supporting roles, gliding mass 22 chock plug inner planes and damping roller near, make the damping roller smoothly go into groove during revolution.O shape is cut down sheet 36 sealing oilholes, and fluid stops to flow.
Rotating shaft drive damping roller 26 makes hollow gliding mass 22 up when applied force is closed; produce negative pressure below the fuel tap; butterfly spring 33 is transferred when assembling certain precompression; compress O shape and cut down sheet; it can not be opened; fluid can only enter after throttling oilhole 31 is by adjustment screw 34 current limlitings below the fuel tap; define the speed of gyration of rotating shaft 8; when applied force surpasses the setting speed of gyration; hollow gliding mass 22 speed uplinks are accelerated; negative pressure increases below the fuel tap; because having surpassed, the suction that the damping metering function of throttling oilhole 31 produces limits the quantity of; replenishing fluid spill oil duct above cutting down seat 32 enters oilhole and opens O shape and cut down sheet 35 and enter below the fuel tap; adapt to the variation of external pressure speed of gyration, played the safety block effect.The magnet 28 that below return spring 27, is provided with, but the effect of magnetizing force absolute oil.
The utility model has the advantages that: closer and hinge and for one, alternative hinge uses, and can dismantle with open-part, and installing does not need other annex; Multistage spring energy-storing and releasing and precompression adjustable mechanism are set, adopt that roller skewed slot plane is spacing, groove location and negative pressure current limliting Adjustable Damping, the two-sided shunting of whole porous valve seat construction, it is spacing to make closer open corner, hydraulic damping control speed is closed automatically, realizes transfiniting a function that back optional position freely stops or locating; Has compact conformation, simple, advantages such as volume is little, cost is low, easy installation, applied range.Be applicable to wings such as furniture, door and window, apparatus.
