Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Referring to Fig. 1-Fig. 6, the opening limit mechanism of the furniture hinge includes a movable cup holder 1 arranged on the furniture door, and a connecting arm 2 arranged on the main body of the furniture. The movable cup holder 1 and the connecting arm 2 are connected by a swing The arms are connected, the connecting arm 2 is provided with a damping device 3, and the hinge is provided with an elastic member 4 that at least generates an opening and closing force for the movable cup holder 1. The rocker arm includes an outer rocker arm 5 and an inner rocker arm 6, and the outer rocker arm 5 A limiting member 7 is arranged between the inner rocker arm 6, and the hinge restricts the opening position through the limiting member 7 at least when the hinge is opened.

The outer rocker arm 5 and the movable cup holder 1 are hinged through a pin shaft 8 , and the limiting member 7 is arranged between the outer rocker arm 5 and the pin shaft 8 . At least when the hinge is opened to a certain position, the inner rocker arm 6 touches and connects with the limiter 7 and positions each other. The limiting member 7 is at least partly made of elastic plastic, and is provided with an elastic part 7.1 and a positioning part 7.2, and is positioned on the outer rocker arm 5 and/or pin 8 by the elastic part 7.1 and the positioning part 7.2 .

On the basis of not changing the original structure of the hinge, a limiting member 7 is arranged between the outer rocker arm 5 and the inner rocker arm 6, because the limiting member 7 is arranged between the outer rocker arm 5 and the inner rocker arm 6, and the inner rocker arm 6. When the hinge is opened to a certain position, it touches and connects with the limiter 7 and positions each other, so the opening position of the hinge is limited. Users can choose limiter 7 with different thicknesses according to actual needs, thereby changing the opening angle of the door body . The hinge opening position of this embodiment is preferably 80°-90°.

In order to facilitate the user to better change the opening angle of the door body, the limiter 7 is provided with an adjustment device, and the limiter 7 changes the relative position with the inner rocker arm 6 through the adjustment device to realize the adjustment of the opening position of the hinge.
