201110186268.5 disclose a kind of hinge of adjustable angle in number Chinese utility model patent, this hinge not only can adjust multiple angles, and when being used in large volume and luxurious furniture that such as decorative leather crosses, the phenomenon that fold appears in covering can be alleviated, liking thus deeply by client.
Form a parallel-crank mechanism between the connection bracket of this hinge and swing arm, a rocking bar then in parallel-crank mechanism by gangbar and fixed arm hinged, swing arm is hinged with fixed arm again.Like this, when making swing arm rotate relative to fixed arm, gangbar will promote parallel-crank mechanism action, makes the arm translation of connection bracket opposing oscillatory and stretches or retract, and just by skin drawing, thus can eliminate fold during stretching, extension.
But the connection bracket of this hinge and swing arm form parallel-crank mechanism, thus away from swing arm, thus can cause large perpendicular to size change on the direction of swing arm in the process of the motion of its opposing oscillatory arm, impact is installed and is used; And this hinge arrangement is comparatively complicated, not only cause manufacturing cost higher, difficult quality controls, and the structure of complexity also can cause work unreliable, easily stuck, even damages, and thus needs to improve.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Adjustable Angle Hinge, distance when solving existing Adjustable Angle Hinge action between connection bracket and swing arm becomes greatly, and hinge arrangement is complicated, manufacturing cost is high, difficult quality guarantee, the insecure problem of work.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of Adjustable Angle Hinge, comprise fixed arm, swing arm, gangbar, connection bracket and stroke amplifying mechanism, one end of described fixed arm and swing arm is hinged, and one end and the fixed arm of gangbar are hinged; Described connection bracket is slidably arranged on a swing arm; The other end of gangbar is connected with connection bracket power by stroke amplifying mechanism, drives connection bracket opposing oscillatory arm to slide by stroke amplifying mechanism.
In preferred technical scheme, described stroke amplifying mechanism comprises rocking bar and connecting rod, and one end and the swing arm of described rocking bar are hinged, and one end of the other end and described connecting rod is hinged, and the other end of connecting rod and connection bracket hinged; Described gangbar by hinged with the middle part of rocking bar, and realizes being connected with the power of stroke amplifying mechanism.
Further in preferred technical scheme, described swing arm is provided with chute, and described connection bracket is stuck on described chute, and can reciprocatingly slide along described chute.
Further in preferred technical scheme, described connection bracket comprises rack body, stiffener is connected guide pillar with two, and rack body, stiffener are respectively in swing arm both sides, and rack body is connected guide pillar with stiffener by two is fixedly connected with; Two connect guide pillar is positioned at described chute, and connection bracket connects guide pillar by two and is stuck in chute and can reciprocatingly slides along chute.
Again in further preferred technical scheme, for rotating shaft hinged with gangbar, connecting rod and swing arm respectively on described rocking bar, between two relatively turnable parts, be also provided with plastic spacer.
The beneficial effects of the utility model are:
Have employed a kind of Adjustable Angle Hinge of technical solutions of the utility model, because its connection bracket is slidably arranged on a swing arm, when swing arm rotates relative to fixed arm, the distance between connection bracket and swing arm can not change, and thus can not affect and install and use; And owing to being provided with stroke amplifying mechanism, can ensure that connection bracket has enough strokes, thus guarantee effectively to eliminate fold; In addition, the Adjustable Angle Hinge structure of this patent is simple, manufacturing cost is lower, work is more reliable.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
