In the installation of door, hinge is one of them important installing component, initial hinge effect is connected on door hinge on doorframe exactly, and along with the development of society and the needs of people, the automatic closing function of door obtains the accreditation of people, develop many various door closers, but the installation of door closer needs certain ambient conditions and easily damages, so people devise the hinge of band automatic door-closing function, but because the volume of hinge has certain restriction, so market is closed the dynamics needed for unlatching of door hinge and automatic door-closing dynamics is direct ratio, if so just cause and think that effort to close is enough, when that opens the door, the thrust of people just becomes large, make often to want the door of switch just to seem to facilitate not and human oriented design.
Utility model content
The purpose of this utility model is to provide one and closes door hinge, it makes door there is existence when reset force is broken away from angle and closes when opening by clutch and hydraulic pressure accelerating structure and closes an acceleration angle, people are touched when opening the door just can, have during automatic door-closing and enough close a dynamics, and volume is little, lightweight, convenient for production.
Technical solution of the present utility model is at verso sheet, recto sheet, axle core, on the basis of pad, the axle core being characterized in described is by upper end cover, speed control rod, hydraulic pressure storehouse, main shaft, torsion spring, clutch, bottom end cover forms, and in the tubular cavity that the hinge eyes that axle core is inserted into verso sheet and recto sheet is formed, the upper rotor part of clutch is fixedly connected with the lower hinge eyes of recto sheet, the rotor of clutch is fixedly connected with the lower hinge eyes of verso sheet, and hydraulic pressure storehouse is fixedly connected with the middle hinge eyes of recto sheet; Described upper end cover, hydraulic pressure storehouse, main shaft, clutch, bottom end cover is connection successively from top to bottom, and the crown center place in hydraulic pressure storehouse is provided with adjusting rod, and the shaft of adjusting rod is inserted in hydraulic pressure storehouse relative with the pressure speed governing hole of spindle top middle; The top of main shaft to be inserted in hydraulic pressure storehouse and can to form piston movement in hydraulic pressure storehouse, and spindle top middle is provided with pressure speed governing hole, the side in pressure speed governing hole is provided with cushion hole, in cushion hole, is provided with steel ball; The axle body being inserted into that section of main shaft in hydraulic pressure storehouse is provided with a bit of spiralling bar shaped perforation, connecting rod is inserted with in this hole, the two ends of connecting rod are connected with the inwall in hydraulic pressure storehouse respectively, the bottom of main shaft is connected with clutch, main shaft between clutch and hydraulic pressure storehouse overlaps and has torsion spring, bayonet socket on one end of torsion spring and hydraulic pressure storehouse clamps, and the bayonet socket on the other end and clutch clamps.
Above-described clutch is by upper rotor part, rotor, Connection Block, clutch steel ball forms, upper rotor part to be from top to bottom inserted in rotor and to have one section of top being inserted into Connection Block, Connection Block is from bottom to top inserted in rotor, be inserted on that section of Connection Block in rotor and be relatively provided with two clutch steel balls placement breach, clutch steel ball is arranged on breach and the cylinder of steel ball protrudes respectively and can contact with the cylinder of the inwall of rotor and that section of upper rotor part inserting Connection Block on the both sides of breach, that section of upper rotor part cylinder inserting Connection Block is relatively provided with two grooves, and two grooves are also relatively provided with on the inwall of rotor.
By the upper rotor part of gemel connection clutch when operating principle of the present utility model is unlatching or the closedown of door, rotor and hydraulic pressure storehouse, after door opening angle is to 90 degree, the groove surface of the clutch steel ball slip rotor in clutch, upper rotor part forces clutch steel ball to be close in the groove of rotor, upper rotor part and rotor depart from interlock state simultaneously, the reset force of now door disengaging torsion spring can freely rotate, after when door, when closing, angle is less than 90 degree, anti-phase clutch steel ball makes upper rotor part and rotor enter interlock state, the reset force of torsion spring resets door at leisure, when resetting to certain angle, adjusting rod inserts the pressure speed governing hole of main shaft, the reset speed making pressure strengthen opposite house is accelerated, door is made to have enough dynamics automatically to reach locking state.
The utility model has the advantages that rational in infrastructure, make door there is existence when reset force is broken away from angle and closes when opening by clutch and hydraulic pressure accelerating structure and close an acceleration angle, people are touched when opening the door just can, have during automatic door-closing and enough close a dynamics, and volume is little, lightweight, convenient for production.
