Abstract

The utility model discloses a gas-liquid piston cylinder hinge, which belongs to door hinges, particularly suitable for cabinet furniture. The aim is to slow down the opening and closing movements of door hinge and to avoid rapid opening and closing action of spring hinges. The utility model adopts a hydraulic cylinder structure with gas and liquid flexibility, as well as overflow damping effect, and is composed of a movable holder, a fixing holder, an L-shaped arc rotating arm, a fixing arm and a rotation shaft. The movable holder (2) is fixed to the door; the fixing holder (7) is fixed on a wall cabinet. The utility model is characterized by a gas-liquid piston-cylinder (1) whose tail part (8) is fixed inside the fixing holder, while the other end of the gas-liquid piston-cylinder is provided with a piston rod (6); the piston rod is connected with the L-shaped arc rotating arm (4) through a piston rod rotation shaft (5); the gas-liquid piston cylinder is composed of a cylinder block (21), the piston rod (6), a piston ring (14), an air pressure sealed ring (13), a location limit ring (15), and an airtight ring (16).

Description

Gas-liquid piston cylinder hinge

Technical field:

Utility model gas-liquid piston cylinder hinge belongs to door hinge, is applicable to the hinge of box-type furniture especially.

Background technology:

The hinge of daily household wardrobe has hinge hinge, spring hinge etc.Though the hinge hinge is simple, the position of the switch easily changes, and spring hinge is because the effect of spring, and the folding position of door is more stable, but close or action during hinge-opening swift and violent, easily hurt sb.'s feelings, particularly easily injure children.

Summary of the invention:

The purpose of utility model gas-liquid piston cylinder hinge is to make the door hinge opening and closing movement slow, overcomes the quickly opening and closing action of spring hinge.

Gas-liquid piston cylinder hinge adopts the hydraulic cylinder structure of elasticity and overflow damping action with gas, liquid, reaches the object of the invention.

Gas-liquid piston cylinder hinge is 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, and gas-liquid piston cylinder cylinder body afterbody is fixed in the holder, its other end has piston rod, and piston rod is connected with " L " type arc cursor by rotating shaft.The gas-liquid piston cylinder by garden cylindricality cylinder body,, piston rod, piston ring, pressurized seal ring, spacing ring, joint ring is formed; Piston ring, spacing ring, joint ring are docile and obedient preface and are installed on the piston rod, piston ring is fixed on the piston rod tail end, the pressurized seal ring is between piston ring and cylinder body afterbody, they are separated to form cylinder body: air-pressure chamber, form first hydraulic pressure chamber between gas seal ring and the piston ring, and form second hydraulic pressure chamber between piston ring and the joint ring, gas seal ring is at the cylinder body afterbody, adopt movingly between garden and the cylinder body outside it, and excircle has sealing ring.The piston ring both ends of the surface have spout hole to communicate, and there is sealing ring in outer garden, adopt movingly between joint ring, spacing ring and piston rod and the cylinder body, and the inboard wall of cylinder block between spacing ring and the joint ring has boss, is used to limit the displacement of spacing ring.

The gas-liquid piston hinge opening and closing freely, easily can not crush staff.

1, gas-liquid piston cylinder 2, sliding seat 3, fixed arm 4, " L " type arc cursor 5, piston rod rotating shaft 6, piston rod 7, holder 8, piston rod cylinder body afterbody 9, fixed arm rotating shaft 10 in the holder, fixed arm rotating shaft 11 in the sliding seat, " L " type arc cursor rotating shaft 12 in the sliding seat, L in the holder " type arc cursor rotating shaft 13; pressurized seal ring 14; piston ring 15; spacing ring 16; joint ring 17; air-pressure chamber 18, first hydraulic pressure chamber 19, second hydraulic pressure chamber 20, boss 21, cylinder body 22, sealing ring B 23, sealing ring A24, spout hole 25, axle.

The specific embodiment:

Now use an Examples set gas-liquid piston cylinder hinge, gas-liquid piston cylinder hinge is by sliding seat 2, holder 7, " L " type arc cursor 4, rotating shaft, fixedly pivoted arm 3 is formed (Fig. 1,2) it mainly contains piston rod 1 (Fig. 3), piston rod cylinder body 21 afterbodys 8 usefulness axle 25 is fixed in the holder 7, piston rod 6 usefulness piston rod rotating shafts 5 are connected with " L " type arc cursor 4, one end of fixed arm 3 is connected the other end with fixed arm rotating shaft 9 in the solid moving seat respectively and is connected with sliding seat 2 with fixed arm rotating shaft 10 in the sliding seat with holder 7, one end of " L " type arc cursor 4 is connected with sliding seat 2 with " L " type arc cursor rotating shaft 11 in the sliding seat, the other end is with L in the holder " rotating shaft 12 of type arc cursor is connected (Fig. 1; 2) with holder 7, and gas-liquid piston cylinder 1 interior (Fig. 3) has pressurized seal ring 13; piston ring 14; spacing ring 15; joint ring 16; piston rod 6 begins ring installation successively from tail end, spacing ring, joint ring.Pressurized seal ring 13 is installed between piston ring and the cylinder body afterbody, has formed air-pressure chamber 17, the first hydraulic pressure chambers 18, the second hydraulic pressure chambers 19 like this in cylinder body.Piston ring 14 has spout hole 24, and spout hole communicates first and second hydraulic pressure chamber.In the cylinder body hole wall between joint ring and spacing ring boss 20 is arranged,, " 0 " type rubber seal A22 and B23 are arranged respectively on close ring of air pressure and the piston ring so that the displacement of restriction spacing ring is movingly between spacing ring and piston rod and the cylinder body.Give in air-pressure chamber and charge into suitable pressed gas earlier, hydraulic pressure chamber also injects liquid.

Fig. 1, Fig. 2 is the opening position of gas-liquid piston cylinder hinge, use: when will be at closing time, sliding seat 2 inhours 10 are rotated around the shaft, rotating shaft on the sliding seat 11 simultaneously drives " L " type arc of rotation sheet 4 12 commentaries on classics clockwise around the shaft, therefore, " L " type arc of rotation sheet is pulled outwardly piston rod 6 by rotating shaft 5, at this moment, first hydraulic pressure chamber, 18 volumes increase gradually, pressurized seal ring 13 moves toward first hydraulic pressure chamber 18 under the effect of air-pressure chamber 17 compressed air power, the liquid of second hydraulic pressure chamber 19 by compression simultaneously, spacing ring 15 stops after being forced into boss 20 positions of cylinder body 21, piston rod continues outwards to move, and the second hydraulic pressure chamber liquid continues pressurized, and joint ring 16 seals, do not allow hydraulic pressure flow out cylinder body outward, and there is small amount of liquid to enter first hydraulic pressure chamber, reduces the resistance of closing the door that the second hydraulic pressure chamber liquid pressurized produces, thereby can close the door like a cork by the spout hole 24 of piston ring 14.Course of action when opening the door and liquid flow direction are opposite when closing.
