Abstract

The utility model relates to a furniture hinge, comprising a connection arm, a movable seat, an elastic piece, an inner swing arm and an outer swing arm hinged between the connection arm and the movable seat; an extension arm arranged on a back end of the inner swing arm, wherein a first end of the elastic piece is overlapped on the extension arm and a second end of the elastic piece is connected with the connection arm or the outer swing arm; more than one support point is arranged between a top surface of the inner swing arm and the first end of the elastic piece and before the extension arm. The support point is arranged before the extension arm and between the top surface of the inner swing arm and the first end of the elastic piece and when the hinge is mostly completely opened, the support point is contacted with the first end of the elastic piece to counteract a large part of the power of the first end of the elastic piece acted on the extension arm of the inner swing arm, therefore the inertia of the hinge is reduced and the service life of the hinge is increased. The structure of the furniture hinge is simple and reasonable and the cost of the furniture hinge is low.

Description

A kind of hinge for furniture

Technical field

The utility model relates to a kind of hinge for furniture.

Background technology

For improving the utilization rate of torsion spring active force in the hinge, I have designed like Figure 13 and hinge for furniture shown in Figure 14, and it comprises torsion spring 3 ', outer rocker arm 4 ' and inner rocker arm 6 '; Inner rocker arm 6 ' afterbody is provided with extension arm 6.1 ', and torsion spring first end 3.1 ' overlap joint is on extension arm; Second end 3.2 ' of torsion spring joins through middleware 9 ' and outer rocker arm 4 '.The hinge of this structure is when opening fully; Because torsion spring first end still applies active force to the extension arm of inner rocker arm, make it toward opening direction deflection, just because of the characteristics of this structure are to improve the utilization rate of torsion spring active force; So; When causing hinge to be opened fully, continue to have bigger inertia motion, the long-term use causes hinge that shakiness is installed.

The utility model content

The purpose of the utility model aims to provide a kind of simple and reasonable, long service life, hinge for furniture that cost is low, to overcome weak point of the prior art.

A kind of hinge for furniture by this purpose design comprises linking arm, sliding seat, elastic component, and is hinged on inner rocker arm and outer rocker arm between linking arm and the sliding seat; The inner rocker arm rear end is provided with extension arm, and elastic component first end overlaps on extension arm, and elastic component second end joins with linking arm or outer rocker arm; Its architectural feature is to be provided with more than one fulcrum between inner rocker arm end face and elastic component first end, and fulcrum is positioned at the place ahead of extension arm.

Said fulcrum is arranged on inner rocker arm end face and/or elastic component first end.

Said fulcrum is square, trapezoidal, triangle or arc.

Said elastic component is torsion spring or shell fragment.

Said elastic component location is arranged on the hinged place of linking arm and outer rocker arm, and elastic component second end directly or through intermediate connector and outer rocker arm joins, and said elastic component second end is positioned at the below of outer rocker arm top board.

Said elastic component second end is between the two ends of outer rocker arm.

The utility model is provided with fulcrum at the inner rocker arm end face between the place ahead of extension arm and elastic component first end; At hinge when opening fully; Fulcrum and elastic component first end touch; Offset elastic component first end and acted on most power on the inner rocker arm extension arm, thereby the inertia of minimizing hinge improves the hinge life-span.It is simple and reasonable, cost is low.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

First embodiment

Referring to Fig. 1-Fig. 4, this furniture hinge comprises linking arm 1, sliding seat 5, elastic component, and is hinged on inner rocker arm 6 and outer rocker arm 4 between linking arm and the sliding seat.Elastic component is torsion spring 3 (also can be shell fragment).The inner rocker arm rear end is provided with extension arm 6.1, and the posterior part overlap joint of torsion spring first end 3.1 is on extension arm, and torsion spring second end 3.2 joins through intermediate connector 9 and outer rocker arm 4.Be provided with first fulcrum and second fulcrum between inner rocker arm 6 end faces and torsion spring first end, two fulcrums are positioned at the place ahead of extension arm.Distributed and arranged is on inner rocker arm 6 end faces before and after first fulcrum and second fulcrum; First, second fulcrum is all curved.Said intermediate connector 9 is for being fixedly installed on the cross bar of outer rocker arm 4 top boards below, and cross bar is between the two ends of outer rocker arm 4, and torsion spring second end 3.2 overlaps on cross bar.

What also be provided with damper 8 in the above-mentioned linking arm 1 and drive damper touches piece 2; Inner rocker arm 6 also is fixedly connected with and touches the auxiliary 7 that piece 2 is in transmission connection.

Second embodiment

Referring to Fig. 5-Fig. 7; The corresponding torsion spring of the inner rocker arm 16 end faces first bottom portion is provided with a fulcrum 16.1, and the fulcrum bottom is provided with location pins, and inner rocker arm 16 corresponding said location pins are provided with locating hole; Fulcrum 16.1 is arranged on the inner rocker arm end face through location pins, and fixing through welding.Other does not state part with first embodiment.
