Abstract

The invention discloses a hinge capable of automatically positioning, which comprises a cylinder body fixedly connected with a first hinge part, wherein the cylinder body is internally provided with a piston, one end of a screw rod passes through the piston, and the other end thereof is fixedly connected with a second hinge part; a first guiding device is arranged between the piston and the inner surface of the cylinder body; the cylinder body is internally provided with a first bias pressure part used for providing an axial response bias pressure to the piston, and a positioning and locking part used for positioning and locking the first hinge part and the second hinge part; and a sealing chamber formed in the cylinder body is filled with damping medium, and a clearance is reserved between the inner surface of the cylinder body and the piston so as to lead the damping medium to move from one side of the piston to the other side of the piston. The hinge capable of automatically positioning has good handfeel, and is labor-saving and closed slowly when in use.

Description

technical field [0001] The present invention relates to a hinge. Specifically, it is a hinge with automatic positioning function. Background technique [0002] Chinese patent document CN87105418A discloses an improved spring hinge with a damper, which includes two cylinders, which are respectively connected with leaves fixed on the door and the door frame, and one of the cylinders forms a sealed cavity A threaded piston is placed in the sealed chamber, which is fixed on a rotating shaft with a large pitch through the threaded piston, and the rotating shaft passes through a central hole on a closed cover plate of the sealed chamber and extends into the second cylinder, while The rotation of the second cylinder makes the rotating shaft rotate in the sealing cavity filled with hydraulic oil, so that the piston moves along the axial direction of the cylinder, and then squeezes the hydraulic oil in the sealing cavity from a small hole formed on the piston to the piston. When th...
