Description

A hinge with stepless adjustable buffer angle

technical field

The utility model relates to a furniture hardware fitting, in particular to a hinge with stepless adjustable buffer angle.

Background technique

At present, most of the existing hinge structures widely used in furniture include hinge cups, hinge arms and bases connected in sequence, and the hinge cups and bases are respectively fixed on the door panel and the rail body. During the opening and closing process of the hinge, in order to generate the elastic pre-tightening force for automatic closing, a torsion spring is usually provided on the hinge cup. Through the pre-tightening force of the torsion spring on the hinge cup, the hinge cup can automatically close after rotating to a certain angle. closure. However, since the torsion spring is continuously stressed during the opening and closing process of the hinge, the elastic coefficient of the torsion spring will gradually decrease after a long period of use, resulting in relaxation, failure, or even disconnection of the torsion spring. The relaxation and failure of the torsion spring reduce the stability of the hinge, so that the hinge cup cannot be automatically closed after multiple rotations or long-term use. In addition, when the torsion spring is disconnected, the rotating mechanism of the hinge cup and the hinge arm is stuck, which greatly shortens the service life of the hinge. Therefore, the existing buffer hinge structure still needs to be further improved.

At the same time, the existing hinge is affected by the acceleration during the closing process, and the closing speed will become faster and faster, causing the cabinet door to collide with the cabinet body when closing, resulting in greater vibration and noise, and in severe cases, it will cause Damage to related accessories. Therefore, there are some hinges with buffers on the market, but these hinges are fully buffered, and the angle of the buffer cannot be adjusted, so the closing speed of the cabinet door is slower or the closing speed is faster, so that the buffering effect is not obvious.
