The specific embodiment

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

First embodiment

Referring to Fig. 1-Fig. 8, the hinge for furniture of this preload adjustable, comprise linking arm 1, holder 4 and elastic component 3, linking arm is hinged with holder by outer rocker arm 5 and inner rocker arm 2 respectively, one end 3.1 of elastic component is crimped on the linking arm, the other end crimping 3.2 of elastic component is on outer rocker arm, and hinge for furniture is provided with the governor motion of regulating the elastic component pretightning force.This governor motion can be arranged on as required linking arm 1 left side, right side or above, it has bigger compliance and flexibility.Elastic component can according to and needs are selected torsion spring, post spring, flat spring or extension spring etc. for use, select torsion spring in the present embodiment for use.

The technical scheme that present embodiment adopted is: governor motion comprises the eccentric part 7 that the end 3.1 with elastic component 3 joins, and eccentric part joins by rotating shaft 7.1 and regulating wheel 6; Eccentric part 7 is positioned at the inboard of linking arm 1, and regulating wheel 6 is positioned at the outside of linking arm.The periphery of regulating wheel 6 and/or end are provided with socket 6.1, have provided the concrete structure that socket is set in the periphery and the end of regulating wheel respectively among the figure, see Fig. 4 and Fig. 5.Slippage takes place by the end face butt joint of flat to prevent it in regulating wheel 6 and rotating shaft 7.1.Can strengthen the fixing of regulating wheel with snap ring 8.For eccentric part and rotating shaft, both can integrated design, as Fig. 3-Fig. 5, also can the split design, as Fig. 6-Fig. 7.Eccentric part in the present embodiment adopts cam.

Also can adopt the adjusting rocking handle to be substituted for the regulating wheel in the technique scheme 6.When adopting the adjusting rocking handle, except obtaining with the identical technique effect of above-mentioned technical scheme, can also obtain the technique effect of others, as regulating rocking handle time spent not, just when not needing that elastic component carried out the adjusting of pretightning force, both can regulate the rocking handle folding storage in the side of linking arm, also can take off separately and deposit, thereby can reduce the volume of whole hinge for furniture regulating rocking handle.

Present embodiment also can be achieved by following technical proposal: governor motion comprises the eccentric part that the end 3.1 with elastic component 3 joins, this eccentric part is set in place in linking arm 1 and is fixed on the bearing pin 2.1 on the linking arm, one end of this bearing pin joins with regulating wheel after stretching out linking arm outwardly, and this part content does not have diagram.The periphery of regulating wheel and/or end still can be provided with socket as required.Wherein, an end of inner rocker arm 2 joins by bearing pin 2.1 and linking arm 1.Because bearing pin 2.1 is to be fixed on the linking arm, when linking arm rotated, bearing pin also rotated simultaneously, so the technical program can obtain the technique effect identical with technique scheme.The other end as for inner rocker arm 2 is then hinged with holder, and this point is consistent with prior art.

In technique scheme, can add damper, be provided with, to obtain further effect as the damper in the background technology.

Second embodiment

Referring to Fig. 9-Figure 11, governor motion comprises the support 12 that is arranged on linking arm 1 side, what adjustment screw 11 was rotated is arranged in the support, and slide block 13 is spirally connected with adjustment screw by the screwed hole 13.1 that is provided with on it, and an end of slide block stretches in the linking arm and an end 3.1 of elastic component 3 joins.

Support 12 is provided with locating hole 12.1 and following locating hole 12.2, after one end of adjustment screw 11 passes locating hole, pine is enclosed within down in the locating hole, that is to say, adjustment screw can only be done the plane and rotate in support, and can not move up and down, by rotating on the plane of adjustment screw, move up and down thereby drive slide block.Do to enlarge and handle such as adjustment screw being passed down a end behind the locating hole, can guarantee that like this adjustment screw can rotate, can prevent that again it from coming off.

Support 12 is a semi-closed structure, and its side towards linking arm 1 is provided with opening, and linking arm is provided with pilot hole 1.1, and the end 3.1 that an end that is positioned at the slide block 13 of support passes behind the pilot hole with elastic component 3 joins.This semi-closed structure support 12 can effectively play the dustproof effect, to guarantee the flexibility of governor motion.

All the other are not stated part and see first embodiment, no longer repeat.

The 3rd embodiment

First embodiment and second embodiment are by two rocking arms: outer rocker arm 5 and inner rocker arm 2 are realized, still, also can only adopt a rocking arm to realize.When adopting a rocking arm, an end of this rocking arm joins by bearing pin and linking arm, and the other end and the holder of rocking arm join.

All the other are not stated part and see first embodiment and second embodiment, no longer repeat.
