Abstract

The utility model relates to a damping hinge which comprises a fixed base and a hinged arm, wherein the fixed base is hinged with the hinged arm through a rotating connecting piece and an inner connecting piece, one end of a torsional spring is supported on and connected with the rotating connecting piece, the other end of the torsional spring is supported on and connected with the inner connecting piece, a damper is arranged in the hinged arm, a triangular connecting piece is formed by the way that a sheet is stamped and bent, a rear corner through hole, a front corner through hole and a lower corner through hole are arranged on the two sides of the triangular connecting piece, the rear corner through hole of the triangular connecting piece is hinged with the piston rod of the damper, the front corner through hole of the triangular connecting piece is hinged with a row-type shrapnel, the lower corner through hole of the triangular connecting piece is rotatablely hinged in the hinged arm, and the row-type shrapnel is hinged with the rear through hole of the inner connecting piece. The damping hinge has the advantages that the structure is simple, and the assembly is easy.

Description

A kind of damp hinge

Technical field

The utility model relates to a kind of hinge of architecture advances, specifically, relates to a kind of damp hinge.

Background technology

Chinese patent 200720052664.8 discloses a kind of oil pressure damp hinge, and its assembly is too many, especially arranges the formula shell fragment and the brace number is numerous, complex structure, assembling trouble.

Summary of the invention

The purpose of this utility model is at above-mentioned existing problems, and a kind of simple in structure, easy damp hinge of assembling is provided.

The purpose of this utility model is achieved in that and comprises holder and pivoted arm, and holder is hinged by rotating connector and interconnecting piece and pivoted arm, and the end support of torsionspring is connected to rotating connector, and the other end support of torsionspring connects interconnecting piece; Be provided with damper in the pivoted arm, the triangle connector is by a sheet material punching press and bends is the connector that there are relief angle through hole, anterior angle through hole and the inferior horn through hole of symmetry in both sides, the piston rod of its relief angle through hole and damper is hinged, its anterior angle through hole is hinged with row's formula shell fragment, and its inferior horn through hole is articulated in the pivoted arm with being rotated; The back through hole of row's formula shell fragment and interconnecting piece is hinged.

The utility model, interconnecting piece are by a sheet material punching press and bend is the connector that there are back through hole, middle through hole and the preceding through hole of symmetry in both sides.

The utility model has simple in structure, the easy advantage of assembling.

Following embodiment is further described the utility model in conjunction with the accompanying drawings.
