Description

Built-in positioning hinge

Technical Field

The utility model relates to the technical field of hinges, in particular to an internally-installed positioning hinge.

Background

A hinge is a mechanical device that connects two solids and allows relative rotation between the two.

The existing hinge can only realize the relative rotation between the two, and has no positioning function; for example, when the door is used at the upturned door, the upturned door can not be fixed by itself when being opened, and the upturned door needs to be kept in an opened state by matching with a stay bar or a gas spring; the vertical hinged door is applied to a vertical hinged door, and a floor spring is matched with a door closer to keep the vertical hinged door in an opened or closed state.

For example, chinese patent No. CN203669573U discloses a positioning hinge assembly, which can prevent or at least make the door not easily affected by gravity or elastic inertia from rotating toward the frame by friction resistance, so that the door can be maintained in the open position without using additional hardware equipment, and can save cost and space. But this hinge can not realize hovering of multi-angle, and because two hinges set up side by side and lead to the angle of opening and shutting limited, can't realize the expansion of bigger angle to the installation hatch door.

For the problems in the related art, no effective solution has been proposed at present.
