Hinge capable of limiting opening angle of furniture door

Abstract

The invention discloses a hinge capable of limiting the opening angle of a furniture door. The hinge capable of limiting the opening angle of the furniture door comprises a movable hinge cup, a hinge arm and elastic pieces, wherein the elastic piece are arranged on the movable hinge cup and act on the hinge arm, and the hinge arm is arranged on the movable hinge cup in a rotary mode through a supporting piece. The hinge capable of limiting the opening angle of the furniture door is characterized in that the hinge arm is made of metal, a cylinder part is integrally formed in the middle of the hinge arm, the supporting piece is arranged on the movable hinge cup in a rotary mode through a through hole in the cylinder part, action parts provided with arc surfaces are integrally formed on the two sides of the cylinder part, one end of each elastic piece acts on the corresponding action part, and a plastic limiting piece with certain elasticity is arranged on the inner side of the hinge arm and is supported by the movable hinge cup in a rotary mode through the hinge arm to limit the opening angle of the hinge. According to the hinge capable of limiting the opening angle of the furniture door, the plastic limiting piece is arranged on the hinge arm and is supported by the movable hinge cup by rotating the hinge arm, so that the opening angle of the hinge is limited, the closing angle of the hinge is not limited, and the practicability is high.

Description

technical field [0001] The invention relates to a hinge, in particular to a hinge capable of limiting the opening angle of a furniture door. Background technique [0002] The Chinese patent literature number is CN201339380, which discloses a hinge on January 9, 2009, which includes a door box, a connecting rod, a hinge arm, a shift arm, a base, a buffer, a torsion spring, a link and a lever drive piece, and the link The device is a fan-shaped structure, which has a center hole and 3 peripheral holes, through which the center hole is movably connected to the hinge arm for positioning, and 1 peripheral hole is movably connected to the piston rod end of the buffer, and the remaining 2 peripheral holes are equipped with shafts. The lever driving piece is provided with an end hole and a middle hole, and the other end opposite to the end hole is provided with two fork mouths, and the lever driving piece is movably connected to the hinge arm through the middle hole, so that the two...

AI Technical Summary

Problems solved by technology

It is said that the structure is simple, the performance is reliable, and the use is flexible. However, due to the effect of the buffer, this structure requires a large force to open or close the door, which may easily cause damage to the handle on the door or the door cannot be closed properly. And the hinge of this structure is not convenient enough to use, and cannot adjust and limit the opening angle of the furniture door, and cannot meet the needs of users.
