A hinge opening and closing force adjustment mechanism

Abstract

An actuating strength adjustment mechanism for hinges comprises a connecting arm, a hinge cup base, a transmission arm component, a damper and an elastic device, wherein two ends of the transmission arm component are respectively in rotational connection with the connecting arm and the hinge cup base; the connecting arm is hinged to the hinge cup base via cooperation between the transmission arm component and the elastic device so as to realize hinging actuation of hinges; the transmission arm component at least comprises a first transmission arm and a second transmission arm; the elastic device is arranged on the second transmission arm and comprises an elastic element and an actuating element; an adjusting piece is rotationally located on the second transmission arm; an adjustment acting part is arranged on the adjusting piece; one end of the elastic element acts on one end of the actuating element, and the other end of the elastic element acts on the adjusting piece; elastic action between the other end of the actuating element and the first transmission arm is realized during actuating of the hinges; and the adjustment acting part is operated by tools or hands, the adjusting piece is rotationally located, and elasticity exerted onto the actuating element by the elastic element is compressed or released to realize actuating strength adjustment of the hinges. The actuating strength adjustment mechanism for the hinges is high in practicability.

Description

technical field [0001] The invention relates to a hinge opening and closing strength adjustment mechanism. 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 wor...

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 lot of noise when it collides. At the same time, the strength of the hinge cannot be adjusted when it is opened and closed, which cannot meet the daily needs of users.
