The beneficial effects of the guide rail hinge integrated device of the present invention are:

(1) This track hinge integrated device not only has the track extension function, but also has the folding function after flipping 180°. It can be widely used in daily life home products such as smart furniture, cabinets, dining tables, office furniture, etc., as a hardware accessory with both track sliding and hinge flipping.

(2) Folding action process: after the movable shell is pulled outward, it is flipped downward 180 degrees and then pushed inward for a distance to complete the 180° folding; unfolding action process: after the movable shell is pulled outward for a certain distance, it is flipped upward 180 degrees and then pushed inward for a distance to complete the 180° unfolding and the snap-fitting of the movable shell.

(3) The track hinge integrated device has the function of transferring the hinge rotation point. Compared with the traditional hinge with only pure rotation function, the rotating hinge of this device can be used as a support point and has a longer force arm, which greatly reduces the disadvantage that the screws at the installation site are subjected to too much force, resulting in the cracking of the wood and the product becoming unusable.

(4) The track hinge integrated device has a self-locking damping function, which relies on an elastic sheet to always press the movable shell, providing a friction resistance in the opposite direction during the outward sliding operation, so that the folding panel of the dining table will not slide out accidentally, thereby improving the sense of stability during operation.

(5) The track hinge integrated device has an interlocking function. Through the limit interlocking device, the movable shell can only slide inward when the movable shell is flipped down to a certain angle. When the movable shell is unfolded, the movable shell cannot slide, thereby preventing the slidable parts from sliding together with the fixed shell after the movable shell is flipped into place.

(6) The track hinge integrated device has height and angle compensation functions. By adjusting the angle adjustment device on the hinge connecting frame, the angle and height of the flip side of the movable shell can be adjusted, thereby compensating for the height or angle error caused by the processing error of the installed surface.
