Description

A kind of furniture blind hinge

Technical field

The utility model relates to a kind of hinge that is installed in door, window, kitchen cabinet etc., the furniture blind hinge of particularly a kind of four connecting rods, seven axis mechanisms.

Background technology

At present, hinge used in everyday is substantially by spring, two bases and the connecting rod that is connected between two bases constitute, the hinge of this mode mainly is an opening and closing movement of realizing door and window by the elastic force effect of spring, because it has used spring to make the actuating unit of folding, make its complex structure, and the elastic force of spring can increase with access times and weaken, it is not tight that door and window is closed, simultaneously because the angle of its folding has certain restriction, to firmly door be pushed into extreme position ability complete opening when opening the door, also to firmly door be pushed into 0 ° of complete driving fit of ability of another extreme position at closing time, cause its noise big, use inconvenient; Disclose a kind of hinge as Chinese patent 02227026.4, comprised support and free bearing, it is provided with a spring base in support, and suit back-moving spring in the spring base can be adjusted at the degree of depth in the furniture preferably; But because it also is to use spring to make the folding actuating unit, so it can weaken because of the elasticity of spring in use for some time and makes the door and window can't be closed.At above shortcoming, Chinese patent 02260925.3 discloses a kind of security door hinge, but comprise and be located in the folding two housings and the runner assembly that is crisscross arranged, its runner assembly is formed by connecting by four connecting rods, seven axle construction, the connecting rod of described runner assembly is formed by stacking by some connecting rods, this hinge can be realized 180 ° of unlatchings, and opens lightly, and noise is little; But because the connecting rod of its employed runner assembly is formed by stacking by some connecting rods, if the connecting rod that therefore overexerts is disconnected by shake easily, as long as there have a connecting rod to be shaken to be disconnected, door and window can not start or stop, makes that the durability of this hinge is poor.

Summary of the invention

The purpose of this utility model is to solve above-mentioned existing problems, provide a kind of not easy to wear, noise is little, durability is strong and furniture blind hinge that can folding between 180 °.

The technical solution of the utility model is achieved in that the utility model comprises moveable hinge base, fixing hinge seat and be located at two linkages between two bases, described two linkages are made up of first connecting rod mechanism that is hinged and second connecting rod mechanism, wherein each linkage comprise respectively with the hinged connecting rod of moveable hinge base and crank arm and and the fixing hinged connecting rod of hinge seat and cranking arm, and the movable end of cranking arm that each connecting rod is corresponding with it is hinged by hinge respectively, and described two middle parts of cranking arm are hinged by hinge.

For further making the door and window folding reach 180 ° effect, said fixing hinge seat and two linkage joints are respectively equipped with support arm, and an end of described support arm is fixed in fixedly on the hinge seat, and its other end is respectively by hinge and connecting rod and crank arm and be hinged.

Be to increase hinge intensity, improve durability, above-mentioned each connecting rod and crank arm to be respectively and be

The frid structure of shape, and described width of cranking arm is greater than the width of cranking arm with connecting rod, the width of connecting rod be less than the width of cranking arm, and the width of cranking arm with connecting rod is close; Connecting rod is nested with in cranking arm respectively rotationally, crank arm be placed on crank arm in.

The utility model has saved spring and had both simplified the structure owing to used two groups of linkages that are hinged, and has reduced the production and assembly difficulty and has made door and window can conveniently be implemented in the breakdown action between 180 ° again; And because its employed each connecting rod and crank arm to be respectively and be The frid structure of shape has improved the intensity and the durability of hinge greatly, thereby makes the advantage that the utlity model has strong, easy to use, the easy popularization of durability, easily realizes.

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

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the utility model comprises moveable hinge base 1, fixing hinge seat 2 and be located at two linkages between two bases, described two linkages are made up of first connecting rod mechanism that is hinged and second connecting rod mechanism, wherein each linkage comprise respectively with the hinged connecting rod 3 of moveable hinge base 1 and crank arm 6 and and the fixing hinged connecting rod 5 of hinge seat 2 and crank arm 4, and each connecting

rod

3,5 is corresponding with it, and

crank arm

4,6 movable end is hinged by

hinge

10,13 respectively, and described two

crank arm

4,6 middle parts are hinged by hinge 15.For further making the door and window folding reach 180 ° effect, said fixing hinge seat 2 and two linkage joints are respectively equipped with

support arm

7,8, one end of described

support arm

7,8 is fixed in fixedly on the hinge seat 2, and its other end is respectively by

hinge

12,11 and connecting rod 5 and crank arm and 4 be hinged.Be to increase hinge intensity, improve durability, above-mentioned each connecting

rod

3,5 and crank arm and 4,6 be respectively and be The frid structure of shape, and described crank arm 6 width greater than crank arm 4 with the width of connecting rod 5, the width of connecting rod 3 is less than cranking arm 4 width, cranks arm 4 to be close with the width of connecting rod 5; Connecting

rod

3,5 is nested with is respectively rotationally cranking arm in 4,6, cranks arm 4 to be placed on and to crank arm in 6.And above-mentioned moveable hinge base 1 middle part is provided with re-entrant cavity 16; Connecting rod 3 is hinged on the back edge of moveable hinge base 1 re-entrant cavity 16 by hinge 9, cranks arm 6 to be hinged on the front of moveable hinge base 1 re-entrant cavity 16 along last by hinge 14.
