Abstract

A large opening-closing amplitude furniture hidden hinge comprises a fixed base, a movable base and a four-connecting-rod retracting mechanism movably connected between the fixed base and the movable base, wherein the four-connecting-rod retracting mechanism comprises a connecting arm and a crank arm movably connected with the fixed base, and a connecting arm and a crank arm movably connected with the movable base, the movably ends of the connecting arms and the corresponding crank arms are respectively hinged through hinge shafts, the middle parts of the two crank arms are hinged with each other through a hinge shaft, and the fixed base is provided with a buffering mechanism connected with the crank arm connected with the fixed base. As the buffering mechanism connected with the crank arm connected with the fixed base is arranged on the fixed base, the four-connecting-rod mechanism retracting mechanism drives the movable base to retract slowly under the buffering effect of the buffering device so that the noise is eliminated and the furniture is also protected against damage, and the hinge has large opening-closing amplitude, accordingly the doors and windows employing the hinges can conveniently open and close within 165 degrees.

Description

A kind of furniture blind hinge of big folding

Technical field

The utility model relates to a kind of furniture blind hinge that is installed in the hinge, particularly a kind of big folding of door, window, cabinet etc.

Background technology

The patent No. is that the Chinese patent of ZL02227026.4 discloses a kind of relating to for the cabinet door, wing or frame can be done the wide-angle folding, easy-to-dismount hinge, this hinge has support and free bearing, and support integral body is inserted in from the groove of rocker arm bracket one bottom portion; rocker arm bracket holds the upper articulation top to have the back link of how much holes therein; rocker arm bracket is on its another side end parts; the next respectively by hinged spring base of hinge and intermediate connecting rod; that the other end of back link and rocking arm are hinged by hinge; the middle-end inboard of rocking arm is by the terminal of the hinged spring base of hinge difference and the middle-end of intermediate connecting rod; suit back-moving spring in the spring base; the hinged front rod of the other end of intermediate connecting rod; the other end branch both sides of front rod are hinged on the end face of the cup-shaped both sides of free bearing by securing member respectively, the other end of rocking arm are hinged on free bearing by hinge and are positioned on the cup-shaped both sides end face of bracket side.Though this hinge is arranged to the structure that four connecting rods fold, and the folding angle is between 90 degree～175 degree, and realized the big folding of hinge, but because it is provided with spring, hinge can fold under the effect of spring fast, thereby produces bigger noise when cabinet door etc. is closed, and influences people's use, the collision that produces certain dynamics when cabinet door etc. is closed, thus cause furniture to be easier to infringement.

Summary of the invention

The purpose of this utility model is at above-mentioned existing problems and deficiency, provides a kind of and has buffer gear and noise is little, can protect furniture not to be damaged and furniture blind hinge that can folding between 165 °.

The technical solution of the utility model is achieved in that

The furniture blind hinge of big folding described in the utility model, comprise holder, sliding seat and be movably connected in holder and sliding seat between four connecting rod retracting mechanisms, wherein said four connecting rod retracting mechanisms comprise the linking arm that flexibly connects with holder and crank arm and the linking arm that flexibly connects with sliding seat and cranking arm, and the movable end of cranking arm that described linking arm is corresponding with it is hinged by hinge respectively, described two middle parts of cranking arm are hinged by hinge, be characterized in described holder be provided with its on the buffer gear of cranking arm and being connected that is connected, described four connecting rod retracting mechanisms are under the cushioning effect of buffer gear and drive sliding seat and slowly fold.

Wherein, above-mentioned buffer gear comprises the cushion cylinder of device in holder, the buffer arm that the buffering transmission arm reaches and the buffering transmission arm flexibly connects that is connected with the cushion cylinder piston rod, described buffer arm and the above-mentioned flexible connection of cranking arm, the width of described buffering transmission arm is less than the width of buffer arm, the width of described buffer arm is less than the width of cranking arm, described buffering transmission arm is nested with in buffer arm and by hinge and is hinged, and described buffer arm is nested with is cranking arm interior and be hinged by hinge.

The utility model since adopt holder be provided with its on the buffer gear of cranking arm and being connected that is connected; make four connecting rod retracting mechanisms under its cushioning effect and drive sliding seat and slowly fold; so both helped abating the noise; help again protecting furniture not to be damaged, thereby solved big folding hinge in the past effectively owing to the problem that makes furniture produce big noise and damage easily when buffer gear causes folding is not set.And owing to adopt four connecting rod retracting mechanisms, make hinge have the characteristics of big folding, thereby make furniture such as door and window can be conveniently implemented in opening and closing movement between 165 °, and because each linking arm and crank arm and be respectively the frid structure that is " ㄇ ", improved the intensity and the durability of hinge greatly, the utlity model has the advantage that durability is strong, easily promote, easily realize thereby make.

Below in conjunction with accompanying drawing the utility model is further described.
