Description
Technical field
The utility model relates to a kind of door and window hardware technical field, particularly relates to a kind of adjustable hydraulic door-closer.
Background technology
Door closer is a hydraulic press for a upper spring-like, by compressing rear release after door being opened, automatically being shut by door, having the effect resembling swinging door, after can ensureing that door is unlocked, accurately, being timely closed to initial position.Modern hydraulic door closer (abbreviation door closer) starts from a patent of twentieth century initial stage American registration, and it is different from traditional door closer, is to reach cushioning effect by carrying out throttling to the liquid in door closer.The core of hydraulic door-closer design philosophy is to realize the control to door closing procedure, and the various functional parameters of door closing procedure are regulated according to human needs.The meaning of door closer is not only door automatically to close, and can also protect doorframe and door body (steadily closing), the more important thing is that door closer has become the very important execution part of of modern architecture intelligent management.Door closer is mainly used in business and public building, but also has situation about using at home.They have a lot of purposes, and wherein topmost purposes is that door is closed voluntarily, limit spreading and the ventilation in mansion of fire.
The basic building block of hydraulic door-closer has supporting guide, travelling gear, back-moving spring, one way valve, tooth bar plunger, throttling valve core and housing, end cap, sealing ring and connecting rod.Housing and connecting rod play a part fixing door closer and are connected door leaf and doorframe.The operating principle of door closer is: when opening the door, the action of door body drivening rod, and travelling gear is rotated, and drives tooth bar plunger to move to the right.In the process that plunger moves to right, spring is compressed, the also pressurized of the hydraulic oil in right chamber.One way valve spheroid on the left of plunger is opened under the effect of oil pressure, and the hydraulic oil in right chamber flows in left chamber through one way valve.After door opening process completes, because spring is compressed in opening process, the elastic potential energy put aside is released, thruster of being turned left by plunger, band nutating gear and door closer link rotatable, makes a closedown.In spring dispose procedure, because the hydraulic oil in the left chamber of door closer is compressed, one way valve is closed, and hydraulic oil can only be flowed out by gap between housing and plunger, and aperture on plunger and 2 runners that throttling valve core is housed are back to right chamber.Therefore hydraulic oil constitutes resistance to spring release, is namely reached the effect of buffering by throttling, and a speed of closing is under control.Choke valve on valve body can regulate, can control different rows journey section, transformablely close a speed.Although door closer structure, the size of different manufacturers production are variant, principle is identical.The kind of door closer can be divided into: door closer (floor spring), vertical door closer (built-in vertical door closer) and other types door closer at the bottom of door closer, door in fitted outside and embedded type door top door closer, embedded type door.Select door closer should consider because have: the weight of door, the width of door, enabling frequency and instructions for use and environment for use etc.The weight of door and the width of door are the main factors selecting door closer model, and common door has labeled door, timber, aluminium alloy door, glass door, steel door etc.The weight of usual door is little, and just select the model that strength is less, vice versa.And frequency of opening the door is closely-related factor with product quality, for using occasion frequently, should require that the sealing performance of product will be got well, the life-span is long.
Current existing door closer in use can not the speed of by-pass cock door, can produce larger vibrations and noise at closing time simultaneously, know from experience produce larger infringement to doorframe and door.
Summary of the invention
