The extension part of the positioning piece directly interacts with the piston rod of the damper or forms a certain gap, which can improve the connection stability of the two when the furniture is opened and closed. It is fastened between the inner hinge arm and the hinge arm elastic member or on the hinge arm elastic member by at least one buckle position, so the positioning member is quite firm after being assembled, and there will be no problem of disengagement during work, so as to further Improve the assembly stability of the damper.

4. Since the damper can be automatically reset through the inner hinge arm, the furniture hinge can choose an automatic reset damper or a non-automatic reset damper, thereby improving the use range of hinge products. At the same time, if a non-automatic reset damper is selected, There is no use of reset elastic parts in the cylinder, which can further reduce production costs, simplify assembly steps and processes, and at the same time reduce the length of the damper, making the overall volume of the furniture hinge lighter.

5. There is a zigzag section between the action part and the groove part, which means that the force can be converted through the zigzag section when the action part interacts with the compression action fitting part and the reset action fitting part respectively, which not only reduces the number of cylinders and internal hinges The friction loss when the arms interact, thereby prolonging the service life of the furniture hinge. At the same time, the zigzag section can realize the uniform acceleration, uniform deceleration, or uniform speed of the hinge opening and closing of the furniture hinge, and also has a certain guiding effect. connection rationality, stability at work and user experience.

In general, it has the characteristics of simple and reasonable structure, reliable performance, high flexibility of use, low manufacturing cost, long service life, easy production, easy realization, beautiful appearance, high safety, and strong practicability.
