Description

For the Hydraulic hinge buffer of door

Technical field

The present invention relates to a kind of Hydraulic hinge buffer for door, espespecially a kind of improve hinge because self rotatory inertia or external force make door shut fast the Hydraulic hinge buffer without buffering effect.

Background technology

The existing Hydraulic hinge buffer for door mainly can make door can return back to the effect of closing door state after providing door one external force, wherein existing Hydraulic hinge buffer is provided with a holder, and combines with this holder rotationally and be located at the buffering group in this holder in order to the folder door group and of sandwiched door, wherein this holder combines with a wall and is provided with a cylinder base in the front side differing from wall, this cylinder base longitudinal running through is provided with a room, and this cylinder base is provided with an action groove communicated with this room in posterior lateral;

This folder gate seat is respectively equipped with one in order to the clamping plate of sandwiched door in the both sides of this cylinder base, this buffering group is provided with a rotating shaft and a piston piece, wherein this rotating shaft be located at this cylinder base rotationally room in and to stretch out this room respectively outer and combine with two clamping plate of this folder gate seat at two ends, allow this folder gate seat this rotating shaft can be driven to rotate relative to this cylinder base when this holder rotates, this rotating shaft is arranged with always flat-shaped and towards the contact surface in action groove direction in middle section, this rotating shaft is made to be positioned at the cross section of middle section slightly in a semicircle, this piston piece to be located at movably in this action groove and to be leant with this rotating shaft, wherein this piston piece have can produce after compression bounce-back promote rotating shaft strength and for carrying out action by oleo cushion mode and being provided with a sleeve leant with this shaft contacts face so as to promoting rotating shaft,

Existing Hydraulic hinge buffer is in time using, this rotating shaft can be driven to rotate relative to this cylinder base via two clamping plate when the door is open, and then the contact surface that leans with this sleeve and this sleeve are separated, and this rotating shaft is positioned at the ora terminalis of this contact surface and this sleeve leans and compresses this piston piece, and when decontrol Men Shike by this piston piece bounce-back promote and make rotating shaft start rotate and drive simultaneously two clamping plate toward close the door direction rotate so that provide door one to automatically reply the effect of closing the door, and add that the rotary speed automatically replied at closing time can make existing Hydraulic hinge buffer produce a rotatory inertia because of the weight of door itself,

But, if when making the speed of axis of rotation be greater than this sleeve driving velocity when automatically replying rotatory inertia or external force at closing time and pushing toward direction of closing the door, this rotating shaft this rotating shaft can be allowed to be positioned at the ora terminalis of this contact surface along with the rotation of door and this sleeve is separated, now, sleeve due to this piston piece is promoted by the mode of oleo cushion, and this rotating shaft is because of without buffer damping effect, and cause this sleeve and fail contact surface that is real-time before door is closed and this rotating shaft leaning and limiting rotating shaft and sleeve synchronization action, so as to providing the effect automatically replying a buffering of closing the door, and must after closing when door, make the sleeve that promotes through oleo cushion just close lentamente and lean with the contact surface of this rotating shaft, in other words only this sleeve has oil pressure damping can provide the effect of buffering, but the rotating shaft of existing Hydraulic hinge buffer has lost the effect of buffering under rotatory inertia or external force push continuous action,

Thus, if automatically reply at closing time, when being subject to as artificially exerted a force toward direction of closing the door, the external force of room conditioning blast or outdoor wind-force etc. or because of existing Hydraulic hinge buffer automatically reply close the door and produce rotatory inertia time, because door is in the process of closing, the sleeve of this piston piece cannot lean with the rotating shaft of this rotation in real time and pin down, the effect that door one can be provided to cushion in the process causing existing Hydraulic hinge buffer cannot close at door, and then to allow the disappearance producing and shut fast, really there are in addition improvements.
