Description

Hinge structure

This creation is about a hinge structure, especially a hinge structure that can improve the anti-collision damage and eliminate the impact sound.

Pressing, the closing force generated when closing the furniture door often causes the furniture door to hit the furniture main body. In order to reduce the impact and noise associated with the closing force, a damping device is installed between the conventional furniture main body and the door panel, and the hinge can effectively eliminate the door panel. The impact force and noise generated when closing, but from the application point of view, the existing hinge automatically switches to the pop-up state when the door panel is opened more than about 60°, and the self-elastic force is greater than the hinge from the maximum opening angle of the door when closing. The pressure is automatically switched to a slow closed state after the door is closed to less than about 60°, and the purpose of the soft and silent closing is achieved. However, the above prior art has the effect of silent closing, and does not consider the problem of the door closing speed. After actual use, Some users will exert excessive force to close the door panel, so that the closing speed of the door panel is too fast, and the damping device of the hinge is usually achieved by the buffer cylinder. When the buffer cylinder is nearly fully contracted, there will be insufficient resistance, resulting in insufficient resistance. Can not effectively eliminate the collision of the door panel, or the damping device has been used for a long time. The puffer cylinder buffer would gradually reduce its resistance, will close causing the door to the closed position of insufficient cushioning effect, this technical problem the desired improvement of the present writing.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After detailed design and careful evaluation, the author has finally achieved a practical and practical creation.

The technical problem to be solved by the present invention is to provide a hinge structure in view of the above-mentioned shortcomings existing in the prior art.
