Damping buffer closing structure for furniture hinge

Abstract

A damping buffer closing structure for a furniture hinge comprises a connecting arm, elastic pieces, a hinge cup seat, a damper, a transmission arm assembly and a poking assembly. The poking assembly is arranged on the transmission arm assembly. The damper is arranged on the connecting arm. The two ends of the transmission arm assembly are rotationally connected with the connecting arm and the hinge cup seat correspondingly. The connecting arm is hinged to the hinge cup seat to open and close the furniture hinge in a hinged manner through cooperation of the transmission arm assembly and the elastic pieces, and an included angle A is formed between the connecting arm and the hinge cup seat. The poking assembly comprises a poking element and an elastic poking element. The poking element is elastically and rotationally located to the transmission arm assembly through the elastic poking element. The damper is provided with an elastic damping element. The damper elastically stretches and contracts to slide on the connecting arm through the elastic damping element. By improving the structure, the damping buffer closing structure has the beneficial effects of being simple and reasonable in structure, excellent in performance, fast and convenient to assemble, long in service life, low in manufacturing cost, easy to produce, easy to implement, safe, reliable, high in practicability and the like.

Description

technical field [0001] The invention relates to a damping buffer closing structure of a furniture 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 worki...

Problems solved by technology

It is said that the invention sets more than two levels 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 levels. , 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 high noise when it collides, which cannot meet the daily needs of users; and the strength of the ornaments acting on the buffer is affected by its torque. The torque of the above structure is short, and the force acting on the buffer is large , the buffering effect is poor
