Buried type hinge structure

Abstract

The invention relates to a buried type hinge structure. The buried type hinge structure comprises a hinge cup and a fixed bracket hinged to each other and opened and closed to match with each other through a connecting arm assembly. An elastic device and a damper are arranged on the fixed bracket. The connecting arm assembly at least comprises a first connecting arm, two ends of the first connecting arm are rotatably connected to the hinge cup and the fixed bracket, separately, and an elastic action part and a damping action part are arranged on the first connecting arm; the first connecting arm is interacted with the elastic device through the elastic action part when the hinge cup is hinged to be opened and / or closed in a certain position relative to the fixed bracket, so that the hingecup is elastically hinged to be opened and / or closed relative to the fixed bracket; and the first connecting arm is interacted with the damper at least through the damping action part when the hinge cup is hinged to be closed in a certain position relative to the fixed bracket, so that the hinge cup is hinged in a damped manner to be closed relative to the fixed bracket. By improving the structure, the buried type hinge structure has the characteristics of being simple and reasonable in structure, reliable in performance, low in manufacturing cost, easy to implement production, smooth to openand close, free of collision, long in service life, safe and reliable and the like, and is high in practicality.

Description

technical field [0001] The invention relates to an embedded hinge structure. Background technique [0002] The Chinese patent literature number is CN201695827U, which discloses a furniture hinge on January 5, 2011, which includes a fixed arm and a movable cup holder connected by a swing arm assembly. The hinge is provided with a spring that at least generates a closing force on the movable cup holder. It is characterized in that the spring is composed of at least two stages of a main spring and an auxiliary spring. It is said that the invention sets more than two stages of springs in the hinge, so that when the hinge is opened or closed to a certain angle, the hinge can be fully opened or closed automatically through the resultant force of the springs at all stages. , the force of the hinge action is borne by the springs of each level respectively, thus greatly improving the service life of each level of spring, especially in the continuous working life test process of cont...

It is said that the invention sets more than two stages of springs in the hinge, so that when the hinge is opened or closed to a certain angle, the hinge can be fully opened or closed automatically through the resultant force of the springs at all stages. , the force of the hinge action is borne by the springs of each level respectively, thus greatly improving the service life of each level of spring, especially in the continuous working life test process of continuously opening and closing the hinge, which can better reflect that there are two levels of springs The life of the above hinge is superior (the continuous opening and closing working life test can exceed 50,000 times), and at the same time, the diameter of the spring can be appropriately reduced; Therefore, when the door is closed and opened, the door body will be affected by the buffer. If the buffer deviates when the door body is opened, it will affect the actual effect of opening or closing the door; and each component in the hinge is point-to-point through the bearing Hinged, with the opening and closing of the hinge, all the force acts on the buffer, which will affect the life of the buffer over time, and this connection method does not have a good buffering effect, which will cause a large collision force between the furniture and furniture. It is easy to be damaged, and there will be a problem of loud noise when it collides, which cannot meet the daily needs of users
