Abstract
The invention relates to a hinge structure to solve the problem that a pin shaft and an end cover at the end portion are likely to get loose in an existing hinge structure. The antifriction and anti-loose hinge structure is provided and comprises a fixed component, a rotating component and the pin shaft. An end cover is arranged below a lower hinge plate, and the end cover is fixedly installed at the lower end of the pin shaft through a threaded mechanism. A ring-shaped antifriction part with the center located at the central axis of the pin shaft is arranged between the end cover and the lower hinge plate. The antifriction part is in a ring shape and is circularly arranged at the lower end of the pin shaft in a sleeving manner. The upper side face of the antifriction piece and the lower side face of the antifriction piece are in tightly contact with the lower side face of the lower hinge plate and the upper side face of the end cover. In the antifriction and anti-loose hinge structure, the antifriction part is used for separating the end cover and the lower hinge plate to achieve the axial supporting function, friction force or friction torque of the movement of the end cover relative to the fixed component is reduced, the end of the pin shaft and the end cover can basically maintain the synchronous movement, the threaded mechanism is not likely to get loose, and the anti-loose performance of the hinge structure can be improved.
