Abstract

The utility model relates to a closing speed control structure of a hinge. The hinge comprises a fixed arm and a movable seat which are connected through an external swing arm and an internal swing arm; a swing block and a damper are arranged in the fixed arm in a rotation mode, and the swing block is also respectively connected with a piston rod of the damper and the internal swing arm; the swing block is connected with the internal swing arm through a sliding chute and a pin shaft, and an inner wall of the sliding chute comprises a hinge closing work surface and a hinge opening work surface; and the hinge closing work surface comprises at least one section of curved surface. The uniformly decelerating or constant-speed closing of the hinge can effectively reduce the sound of collision of a door plate of furniture with a furniture main body; and in order to make the hinge be closed at a uniformly reduced speed or a constant speed, the hinge closing work surface of the sliding chute of the swing block of the hinge is designed into the curved surface, and the component force effected on the hinge closing work surface when a door is closed is greatly reduced or keeps unchanged through modeling curvature of the curved surface and other designs, so the hinge is closed at a uniformly reduced speed or a constant speed.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

Referring to Fig. 4-Figure 11, the closing velocity control structure of this hinge, described hinge comprises fixed arm 2 and the sliding seat 5 that connects by outer swing arm 6, interior swing arm 7; Rotate in the fixed arm and be provided with centering block 12 and damper 8, centering block also joins with the piston rod 8.1 and the interior swing arm of damper respectively; Wherein, join by chute 12.1 and bearing pin 10 between centering block and the interior swing arm, chute inwall two sides are respectively that hinge is closed work plane D and hinge is opened work plane E; Chute 12.1 is arranged on the centering block 12; Bearing pin 10 is arranged on interior swing arm 7.Wherein, chute 12.1 is the arcuate structure that an end opens wide, and work plane D closed by its hinge and hinge is opened all curved surfaces for being made of one section arcwall face of work plane E.

Outer swing arm 6 two ends are hinged with sliding seat 5 and fixed arm 2 respectively; Interior swing arm one end and sliding seat are hinged, and middle part and fixed arm are hinged, and the other end is provided with described bearing pin 10 and joins with the chute 12.1 of centering block 12; The piston rod 8.1 and the centering block of damper 8 are rotationally connected.Outer swing arm 6 bottoms are provided with torsion spring 13, and torsion spring one end joins with outer swing arm, and the torsion spring other end and interior swing arm 7 are joined.
