Damping closing structure of buried-type hinge

Abstract

The invention discloses a damping closing structure of a buried-type hinge. The structure comprises a connecting arm assembly, a hinge cup and a fixed bracket, the connecting arm assembly at least comprises a first connecting arm, and the two ends of the first connecting arm are respectively connected with the fixed bracket and the hinge cup rotatably; an elastic assembly and a damper are furtherarranged on the fixed bracket, and an elastic action part and a damping action part are further arranged on the first connecting arm; when the hinge cup is opened and closed at a certain position in ahinge mode relative to the fixed bracket, the first connecting arm interacts with the elastic assembly through the elastic action part to achieve elastic hinged opening and closing of the hinge cup relative to the fixed bracket; when the hinge cup is closed at a certain position, the first connecting arm and the damper interact with each other laterally at least through the damping action part toachieve damping and hinged closing of the hinge cup relative to the fixed bracket; an arc position is arranged at the position of the mutual lateral action between the damping action part and the damper, the damping action part and the damper interact with each other laterally through the arc position in a point contact mode, or a line contact mode or a surface contact mode, and the practicability is high.

Description

technical field [0001] The invention relates to a damping closure structure of an embedded hinge. 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...

Problems solved by technology

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 colliding, which cannot meet the daily needs of users
