Abstract
The utility relates to a free type floor spring for closing the door capable of freely closing the door when the house door is open. The positioning shafts at two ends of a force supporting arm is flexibly connected with one end of a force transmission chain in a metallic shell and the other end of the force transmission chain is flexibly connected with the positioning shaft at one end of a pull rod of a releasing apparatus. The pull rod of the releasing apparatus restricts a hole through, a location-limited plate and one end of a ring-shaped pressure spring is supported on a pallet at the other end of the pull rod of the releasing apparatus, and the other end of the ring-shaped pressure spring is supported on the location-limited plate. When the door is open without external force, the releasing apparatus drives a door spindle and the door to slowly freely to return to the original position through the force transmission chain, thus reaching the goal of freely closing the door slowly when the door is open.
Description
Technical field: the utility model relates to a kind of device that makes the house door open wide and can freely close, and especially can make the two-way free type door floor spring that can slowly close after unlimited of house door.
Background technology: at present, known house door floor spring is a kind of location type floor spring, and when door reached certain angle, goalkeeper automatically locked, and must apply external force at closing time could close door, and giving needs the user who closes the door to bring inconvenience at any time.
Summary of the invention: must apply the deficiency that external force could be closed door at closing time in order to overcome present location type floor spring, the utility model provides a kind of free type to close a floor spring, this free type closes a floor spring and can not only two-wayly open wide, and door need not apply external force when opening wide and just can freedom slowly close.
The technical scheme that its technical problem that solves the utility model adopts is: in metal shell, power support arm, door-hinge, locating shaft, power transmission chain, slow release device pull bar, annular pressure spring, connect by frame for movement, power support arm, power transmission chain, slow release device pull bar are linked in sequence with locating shaft.The annular pressure spring housing is in the outside of slow release device pull bar, and the slow release device pull bar other end is connected with locating piece, and locating piece is fixed on the metal shell by the locating piece set bolt.Protruding key one end of door-hinge and bearing bore diameter tight fit, and pass metal shell and be connected with the house door; The other end of door-hinge is fixed in the bearing bore diameter, the power transmission chain is flexible coupling power support arm and slow release device pull bar by locating shaft, the swing offset of door-hinge (2) and the straight-line displacement of slow release device pull bar (7) can be changed mutually, annular pressure spring (8) one ends are on limiting plate (6), the other end withstands on the pallet of slow release device pull bar (7), limiting plate (6) to the longitudinal spacing of spring the time again to the cross spacing of slow release device pull bar (7), the compressed heat energy of spring be for the door-hinge return used, sealing ring (13) is enclosed within on plunger (12) locating slot, the sealing ring material adopts elastic body, plunger (12) cover sealing ring one end inserts in slow release device pull bar (7) cylindrical cavity, and it is that fluid chamber (14) fluid chamber (14) has a vertical vent (15) that cylindrical cavity top carbonyl leaves an irregular gap, and the other end of plunger (12) is fixed on the locating piece (9) by plunger set bolt (11).When door applies the external force any direction and opens wide, goalkeeper drives door-hinge and the power support arm rotatablely moves, rotatablely moving of power support arm is transformed into rectilinear motion by the power transmission chain with the slow release device pull bar, because the slow release device plunger is fixed on the metal-back motionless, to produce negative pressure in the cylindrical cavity during motion of slow release device pull bar, to produce negative pressure in the cavity, by small sircle hole liquid in the metal-back is sucked in the cylindrical cavity, simultaneously with annular pressure length of spring compressed storage of potential energy, when the unlimited certain angle of door loses external force, the annular pressure spring discharges potential energy and drives slow release device pull bar straight line return, liquid sprays in metal-back by small sircle hole in the cylindrical cavity, because the damping action of liquid and small sircle hole, the slow release device pull bar is with slow return, the rectilinear motion of slow release device will drive a slowly return of door-hinge and door by the power transmission chain, the purpose that freedom is slowly closed when reaching unlimited.The beneficial effects of the utility model are, can make that the house door is two-way to be opened wide, and slowly close without external force house goalkeeper's freedom, and cost is low, and is simple in structure, easy for installation, replace locking-typed floor spring and need not move the basis and change and get final product.
