The specific embodiment

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

The first embodiment

Referring to Fig. 1-Fig. 8, this furniture hinge, comprise linking arm 1 and sliding seat 2, at least are connected connection with inner rocker arm by outer rocker arm 3 between the two, its outer rocker arm 3 is hinged by outer rocker arm axle 3.1 and linking arm 1, and cover has outer rocker arm spring 3.2 on the outer rocker arm axle 3.1, is provided with a rolling member on the inner rocker arm 4 of the present embodiment, one group of spring pin of outer rocker arm spring 3.2 and outer rocker arm 3 against, other one group of spring pin and rolling member against.

Inner rocker arm 4 is hinged by inner rocker arm axle 4.1 and linking arm 1, cover has inner rocker arm spring 4.2 on the inner rocker arm axle 4.1, the position of corresponding inner rocker arm spring 4.2 is provided with back shaft 4.3 on the linking arm 1, one group of spring pin of inner rocker arm spring 4.2 and back shaft 4.3 against, other one group of spring pin and rolling member against.

Wherein, rolling member can also be arranged on linking arm 1 or the outer rocker arm 3 according to the actual design requirement, and its technique effect that reaches is consistent.Rolling member is roll sleeve 6.1, roller or bearing; Described rolling member is rotatably connected on the inner rocker arm 4 by roller bearing 6.Perhaps, described rolling member is the axle that is rotatably connected on the inner rocker arm 4.It can be replaced with roller or bearing etc. the rolling member of the present embodiment by roll sleeve 6.1(), rolling member is rotatably connected on the inner rocker arm 4 by roller bearing 6.

Overlap respectively on the utility model outer rocker arm axle 3.1, the inner rocker arm axle 4.1 outer rocker arm spring 3.2 and inner rocker arm spring 4.2 are arranged, two springs are shared hinge suffered power when switch, this design can reduce the specification of required spring, usually, the spring of same type, its specification is less, its life-span is then longer, therefore, this design can increase considerably the on-off times of hinge, makes hinge meet higher Application standard.In addition, by set up a roll sleeve 6.1 at inner rocker arm 4, spring pin is against thereon, because rolling member rolls in the process of handle switch, therefore can reduce the friction between spring pin and the rolling member, make the handle switch process more smooth and easy, through long-term use, spring pin can not pressed the rolling member or make rolling member that other distortion occur of collapsing yet.In addition, in order to make the stressed parallel of rolling member, outer rocker arm spring 3.2 and inner rocker arm spring 4.2 are resisted against two groups of spring pins on the rolling member, can be resisted against respectively the both sides of rolling member, perhaps wherein one group of spring pin is resisted against the middle part of rolling member, and other one group of spring pin is resisted against the both sides of rolling member, and the preferred scheme of the present embodiment is the latter, be the middle part that the spring pin of outer rocker arm spring 3.2 is resisted against rolling member, the spring pin of inner rocker arm spring 4.2 is resisted against the both sides of rolling member.Behind the stress balance of rolling member, more can guarantee its phenomenon that can not deform, the application life of further improving hinge.

Be provided with fixed arm 7 in the linking arm 1, be connected with damper 8 in the fixed arm 7, damper 8 one ends are cylinder body, an other end is piston rod, is provided with locating hole 8.1 on the cylinder body, and locating hole 8.1 is connected with linking arm 1 by alignment pin 8.2, be provided with touching 8.3 on the piston rod, touching 8.3 both sides are respectively arranged with lateral pin, and two lateral pins are connected with two a touching brace 8.4 respectively, and two a touching brace 8.4 are connected with linking arm 1 by connecting axle 10.1.

Linking arm 1 be provided with touch 8.3 against touching piece 10, touching piece 10 is in transmission connection by transmission mechanism and inner rocker arm 4, touching piece 10 is connected on the linking arm 1 by connecting axle 10.1, and transmission mechanism one end is hinged with touching piece 10, and an other end and inner rocker arm 4 are hinged.Hinge is in the process of closing, and touching piece 10 can act on touching 8.3, thereby makes damper generation effect, makes hinge obtain closing the effect of buffering.

Wherein, transmission mechanism is made of the driving member 10.2 more than, the present embodiment is preferably two, driving member 10.2 gets final product by punch forming, process very convenient, one end of driving member 10.2 is hinged on the touching piece 10, and an other end of driving member 10.2 is hinged on the inner rocker arm 4, and clearance position makes hinge can finish glibly the action of closing or opening.

Inner rocker arm 4 both sides also are respectively arranged with inner rocker arm brace 4.4, two inner rocker arm braces, 4.4 1 ends and inner rocker arm axle 4.1 are connected with roller bearing and are connected (according to the actual design needs, two inner rocker arm braces, 4.4 1 ends only can also distinguish be connected with inner rocker arm axle 4.1 or roller bearing 6), two inner rocker arm braces, 4.4 other ends are hinged with driving member 10.2 respectively; Perhaps, inner rocker arm 4 one ends and inner rocker arm axle 4.1 are connected roller bearing 6 and are connected with ∕, and inner rocker arm 4 other ends are hinged with driving member 10.2 respectively.

Because the hinge of different size, the location layout of its inner rocker arm 4 is not identical, it causes inner rocker arm 4 not identical with link position between the transmission mechanism, to make separately the technological requirement of inner rocker arm 4 processing complicated if the hinge of different size all configures independent inner rocker arm 4(), will directly cause its cost of manufacture high.And the utility model is by setting up the inner rocker arm brace 4.4 that is connected both between inner rocker arm 4 and the transmission mechanism, by changing the shape of inner rocker arm brace 4.4, can make inner rocker arm 4 become general part, the hinge that is different size can be with same inner rocker arm 4, and the technological requirement of inner rocker arm brace 4.4 processing is very simple, the cost of manufacture of being convenient to save hinge.As shown in Figure 8, inner rocker arm 4 is by punch forming.

In addition, be removably connected with holder 9 on the fixed arm 7.Holder 9 is in-line (or middle font), and holder 9 is provided with governor motion (unlabelled among the figure).Outer rocker arm 3 and inner rocker arm 4 are hinged by U-shaped connector 5 and sliding seat 2, satisfy instructions for use.

The second embodiment

Referring to Fig. 9, the main distinction of itself and the first embodiment is, inner rocker arm 4 forms by the polylith video disc is stacked, and its versatility is higher, can satisfy more designing requirement.

Other do not state part, with the first embodiment, no longer repeat.
