Technical field
The utility model relates to a kind of hinge that is installed on the furniture product, is a kind of modified furniture damp hinge specifically.
Background technology
At present, the Domestic hinge of selling on the market, all continued to use damping mostly, make hinge in folding, have better buffering effect, avoid the cabinet door of furniture product to be subjected to excessive restoring force in moving process and bump with cabinet, this constructed products is subjected to users' favor deeply.Common damp hinge, it comprises hinged in turn hinge cup, linking arm and base assembly, and hinge cup also is connected with the pull bar of isolation damper on being installed in base assembly by the pivoted arm assembly, and hinge glass is subjected to be implemented in after the external force driving folding activity on the base assembly.Wherein, there is a kind of pivoted arm assembly of hinge to take to fan toothing and carries out transmission, it for example is the disclosed a kind of furniture damp hinge of Chinese utility model patent ZL200720047410.7, the related pivoted arm assembly of this patent comprises inner rocker arm and connector, inner rocker arm and connector all are related to the fan toothing, and both running parts all rely on the tooth transmission.Yet, the pivoted arm assembly of this structure, the fan tooth is a thin-wall stamping part, and driving cog is less, after the hinge opening and closing use has certain number of times, the latch phenomenon appears in thin little driving cog easily, folding is dumb, or even tooth collapses phenomenon, and then stuck phenomenon occurs, shortened the application life of product, had a strong impact on product and normally use; And, on thin little inner rocker arm and connector, process driving cog, increased the product manufacture difficulty, improved the manufacturing cost of product; In addition, the damp hinge of this structure, its connector both had been used to pass to the driving torque of inner rocker arm, but also need the pulling isolation damper, the abrasion phenomenon of the installation bearing pin of connector is more obvious, has a strong impact on the normal use of hinge, lowers the application life of hinge.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of folding flexibly, long service life, the simple in structure and modified furniture damp hinge that effectively reduces cost.
Goal of the invention of the present utility model is achieved in that a kind of modified furniture damp hinge, comprise hinged in turn hinge cup, linking arm and base assembly, on the hinge cup U type latch is housed, one end of linking arm is installed on the last arm of U type latch, the other end of linking arm is sold at the bottom of by front end and is installed on the base assembly, on the pin torsion spring is housed at the bottom of the front end, one free end of torsion spring is pressed on the last arm of U type latch, another free end of torsion spring is pressed on the base assembly, the following arm of U type latch is connected with the pull bar of isolation damper on being installed in base assembly by the pivoted arm assembly, hinge cup is subjected to external force to drive the back and is implemented in folding activity on the base assembly by linking arm, it is characterized in that: described pivoted arm assembly comprises duplicated crank and movable rocking arm, the middle part of duplicated crank is installed on the hinged bearing pin of being located on the base assembly, one end of duplicated crank is hinged on the following arm of U type latch, the other end of duplicated crank is provided with the pin that floats, unsteady pin is installed on the rocking arm connecting hole of movable rocking arm and can fluctuates in the cavity of rocking arm connecting hole, the pull bar connecting hole that is located on the movable rocking arm is connected with the pull bar of isolation damper, have laterally steering hole, top and laterally steering hole, below on the movable rocking arm, laterally steering hole, top is installed on the hinged bearing pin, laterally steering hole, below is installed on the fixedly pin of being located on the base assembly, when movable rocking arm was driven by duplicated crank, movable rocking arm was then along laterally steering hole, top and the left and right sides, laterally steering hole, below translation swing.
As the further qualification of technique scheme, laterally steering hole, described top is positioned at the top of rocking arm connecting hole, and laterally steering hole, below is positioned at the right side of rocking arm connecting hole, makes the three arrange more and rationalizes, and can effectively reduce the volume of movable rocking arm.
A kind of concrete mode in technique scheme, laterally steering hole, described top, rocking arm connecting hole and laterally steering hole, below three form " L " type in turn and arrange.
Further refinement in technique scheme, described rocking arm connecting hole is the slotted hole of vertical direction, guaranteed that effectively duplicated crank drives the pin that floats and fluctuates in the rocking arm connecting hole, make movable rocking arm realize that when shaking top is to swing, avoid isolation damper to produce and fluctuate.
And laterally steering hole, described top and laterally steering hole, below are the slotted hole of horizontal direction, and further assurance activity rocking arm is under duplicated crank drive situation, and the translation swing is done in its upper end.
In addition, in the specific implementation process of technical scheme, described movable rocking arm is a U type structure, and the movable rocking arm of U type structure is clamped in the both sides of the pull bar of duplicated crank, isolation damper respectively.This structure can make the pull bar of duplicated crank, isolation damper stressed more even.
In above-mentioned technical scheme, described isolation damper is damping cylinder or damping oil cylinder.
The utility model compared with prior art has the following advantages:
Modified furniture damp hinge provided by the utility model, its pivoted arm modular construction is taked duplicated crank and movable rocking arm fit structure, form the two two rocker structures that join and the transmission damping action, the pivoted arm assembly of traditional fan tooth transmission is changed into two rocker structures, avoided the pivoted arm assembly in transmission process, to occur rotating stuck manifesting, rotate flexible, guarantee that effectively product has long application life, also exempted the manufacturing procedure of fan tooth simultaneously, not only optimized the structure of pivoted arm assembly, product structure is simple, has also reduced the manufacturing cost of product, helps improving competition capability.And, at the pivoted arm assembly is to be designed under the situation of two rocker structures, and the swing hole of movable rocking arm is for fluctuating and laterally floating distribution structure setting mutually, and the installation bearing pin of movable rocking arm is not subjected to the rotating torque effect, can not produce the abrasion phenomenon, effectively prolong the application life of product.
