Abstract
The utility model relates to an adjustable hydraulic damper door closer, which has the structure that a variable triangle is composed of big connecting rods and small connecting rods on big support brackets and small support brackets respectively fixed on a door frame and a door, a piston rod and a sleeve barrel for fixing the piston rod. When the door is closed and opened, the triangle changes, which causes the piston rod to drive a piston fixed on the end of the piston rod to reciprocally move in the sleeve barrel. Energy released by a spring arranged in the shaft direction of the piston causes the door to automatically close, and through holes of an oil path of a valve core on the piston can be regulated to alter the door closing velocity. The adjustable hydraulic damper door closer has convenient installation, rare collision and noise in door closing and opening. When opened to more than 90 DEG, the door can be automatically positioned. The adjustable hydraulic damper door closer not only can be used on doors, but also can be used on windows.
Description
The utility model is a kind of adjustable hydraulic buffering door closer, can directly be installed on the door and window, makes door and window cushion the device of closing automatically.
At present, closing of the door of family and office mostly is by people's control, in order to realize closing the door automatically, installing extension spring or rubber bar outdoors additional, adopts this mode sometimes, and be neither attractive in appearance, makes a generation collision again, accelerated the damage of door, and brought the noise that makes one nervous; In addition, when wet monsoon was big, door was subjected to wind action and collision back and forth easily, and especially glass door is more fragile.
The purpose of this utility model provides a kind of door that makes and closes automatically, when holding together near the pass, door can produce cushioning effect automatically, do not have any collision noise, prolonged the application life of door, and the adjustable hydraulic that door can be located when opening more than 90 ° automatically cushions door closer.
The technical scheme that realizes the utility model purpose is, one end of big connecting rod and piston is movably connected on the big support, big support is fixed on the doorframe, one end of small rod is movably connected on the small rack, small rack is fixed on the door, and the termination three of the other end of big connecting rod and small rod and the sleeve of fixed piston rod is movably connected to form a variable triangle; Piston rod puts on the sleeve termination and is fixed with piston, and to spring is housed, an end of spring withstands on the sleeve inner face along piston rod, and the other end is stuck on the step of piston.
The movable spool that inserts in the mesopore of piston, spool can move along this hole, in the mesopore of piston little spring is housed, and little spring one end withstands on the spool, and the other end withstands on the piston rod, leaves the oil circuit through hole on the piston; The buffering dynamics that is fixed with the control oil channel channel sized on the spool is adjusted screw, adjusts this screw, can change the speed of closing the door; In sleeve, on same center line, be fixed with buffer distance with spool and adjust screw, in the time of can making Men Zaiguan to doorframe, screw has reduced asphalt channel with spool jacking piston, by adjusting this screw, can obtain the desirable buffer distance of closing the door; When Men Kaizhi is more than 90 °,, a dependence wall or other objects are located automatically because the force direction of spring opposite house is opposite.
The utility model is easy for installation, can locate automatically after Men Kaizhi is 90 °; Only when door closes up soon, just slow down the speed of closing the door, therefore avoided collision and noise at closing time, prolonged the application life of door, and the gentle distance of dashing of buffering dynamics can be adjusted as required; Owing to adopted hydraulic oil, self-lubricating is good, and parts depreciation is little, except that being used for also can be used on the window door goes up.
Fig. 1 is installed in vertical view on the door for the utility model;
Fig. 2 is the enlarged drawing of piston and spool part.
Be that embodiment describes structure of the present utility model in detail below with the accompanying drawing.
Operating principle: during door switch, variable triangle changes, and makes piston rod 3 drive piston 6 and moves back and forth in sleeve 4; Spool 7 is ejected by the little spring in the piston 6 15 when opening the door, hydraulic oil is very fast to enter chamber 13 by chamber 12 via through holes 14, compresses spring 5 simultaneously, when spring 5 releases energy, door is closed automatically, move when piston 6 continues towards the chamber 13 under the effect of spring 5, during soon near the bottom of sleeve 4, spool 7 is cushioned apart from the screw 9 jacking pistons 6, through hole 16 is blocked, this moment, hydraulic oil can only force the speed of closing the door to be fallen suddenly by very little gap on the through hole 17, reached the purpose of buffering collisionless and noise.
