Description

A kind of furniture damp hinge

Technical field

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

Background technology

A kind of gas-liquid piston cylinder hinge is disclosed among the Chinese patent CN200320118910.7, by sliding seat, holder, " L " type arc cursor, fixedly pivoted arm, rotating shaft are formed, sliding seat is fixed on the door, holder is fixed on the cabinet wall, it is characterized in that having the gas-liquid piston cylinder, gas-liquid piston cylinder cylinder body afterbody is fixed in the holder, its other end has piston rod, piston rod is connected with " L " type arc cursor by the piston rod rotating shaft, the gas-liquid piston cylinder is by garden cylindricality cylinder body, stopper rod, piston ring, pressurized seal ring, spacing ring, and joint ring is formed.The gas-liquid piston cylinder hinge of this structure is owing to all-in-one-piece " L " type of employing arc cursor, so in its actual use, it is quite stiff that hinge seems, it is all very painstaking to open or close, underaction.

The utility model content

Technical problem to be solved in the utility model be to provide a kind of simple and reasonable, cost of manufacture is low, switch is flexible, the furniture damp hinge of long service life, to overcome weak point of the prior art.

The technical scheme in the invention for solving the above technical problem is: a kind of furniture damp hinge, comprise holder and linking arm, holder is hinged by outer rocker arm and inner rocker arm and linking arm respectively, be provided with damper in the linking arm, its architectural feature is that the piston rod of damper is connected transmission with inner rocker arm by centering block.

Above-mentioned piston rod end and centering block one end are hinged, and the centering block other end or middle part are hinged on the linking arm by bearing pin, and centering block is provided with chute, inner rocker arm is provided with roller, roller is slidingly installed in the chute, and inner rocker arm one end or middle part and linking arm are hinged, and its other end and holder are hinged.

Above-mentioned centering block is that two and above single pendulum sheet are formed by stacking, and it is provided with the opening chute; Single pendulum sheet separation piston rod end left and right sides, alignment pin is passed single pendulum sheet and piston rod successively.

Above-mentioned inner rocker arm is that two and the above sheet that singly shakes are formed by stacking, and its end cross is coated with locating shaft, and roller is arranged on the locating shaft two ends.

The utility model is designed to the branch body structure with original monolithic inner rocker arm, and by when motion extruding chute in the chute of roller on centering block not ipsilateral to transmit the torque of different directions, realize the folding of hinge, and, because roller can slidably reciprocate in chute, so avoided in the past when inner rocker arm turns to the upper and lower dead point of hinge, rotating situation generation laboriously once more, switch is more flexible, has also obtained great prolongation application life.
