Description

Hinge structure

This creation department has a "hinge structure", especially when the hinge body and the movable seat are opened and closed, and can generate a free stroke and a buffer stroke at an appropriate angle, thereby reducing the impact and volume of the opening and closing door panels. Features.

In order to eliminate the impact force and volume generated by the furniture door panel on the furniture body when closing, the damper device is often installed between the door panel and the body of the furniture, thereby slowing down the closing speed of the furniture door panel and reducing the door panel. The purpose of closing the impulse and the volume is that the existing hinge is automatically switched to the pop-open state after the door panel is opened by about 0°~60°, and when it is to be closed, a greater than the hinge self-elastic force is applied from the maximum opening angle of the door leaf. When the pressure closes the door to about 60°~0°, it automatically switches to the slow closed state, achieving the purpose of soft and silent closing.

However, the prior art as described above has the effect of silent closure, but does not take into account that when the door panel is opened, the hinge self-elastic force will generate a huge impact force combined with the weight of the door panel and the self-elastic angle, and the impact force will be transmitted to the hinge body. The joint between the furniture and the furniture, which seriously affects the service life of the hinge and the furniture. On the other hand, the conventional hinge has a torque angle of the hinged state in the closed state due to improper distribution of the hinge spring retracting force, and the opening process is minimal. The maximum torque angle will make the spring prone to elastic fatigue, causing the spring retraction force to rapidly decrease, and even the spring body is broken, resulting in the lack of practicality of the product.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional hinge structure is a goal that the relevant industry needs to work hard to develop.
