Abstract
The utility model discloses an automatic buffer reset hinge for a cabinet door of furniture. The automatic buffer reset hinge for the cabinet door of the furniture is characterized in that a torsional spring is further arranged in a base, a fixed foot of the torsional spring is pressed into a bottom plate of the base, a moving foot of the torsional spring is pressed on a deflector which is arranged on the side wall of the front segment of a composite rocking arm, the deflector is arranged far away from a first hinged hole, the front end of the composite rocking arm is driven by the deflector to upward through spring force, and the automatic buffer reset function of the composite rocking arm is achieved. The automatic buffer reset hinge for the cabinet door of the furniture has the beneficial effects that a forced point of the spring on the composite rocking arm gradually slides from one end close to a spring fulcrum to one end far away from the spring fulcrum during the closing process, the pressure of the spring applied on the composite rocking arm gradually reduces to balance accelerated speed produced by inertia of the cabinet door according to lever principle, and the closed speed of the cabinet door is steady and uniform.
Description
Technical field
The utility model relates to five metals hinge and manufactures field, is the automatic buffer reset hinge of cabinet door use for a kind of furniture specifically.
Background technology
Hinge is for connecting the parts of cabinet and cabinet door in antique traditional furniture Hardware fitting, in current hinge generally all with resilient structures, spring assembly is set in hinge, make to open the door and at closing time hinge be subject to the thrust effect of spring, avoid cabinet door to occur opening or closing the situation of state labile.Yet because spring assembly in use has screen resilience, easily there is the phenomenon of excessive velocities in cabinet door when opening or closing because of the traction of screen resilience.Above-mentioned phenomenon can make cabinet door when closing, send the sound, and can make cabinet shake; Cabinet door recoil of spring power when opening can produce inertia stress to hinge installation place, causes hinge installation position to occur loosening, and long-time use can make hinge occur obscission.Existing solution is that cushion dashpot is set in hinge, and the cushioning effect by cushion dashpot when the hinge open and close reduces the screen resilience impact of spring assembly.But, cushion dashpot needs there is preposition movement in buffering course, and the starting point of preposition movement and terminal are just in time the states that hinge is closed completely or opened completely, so cushion dashpot only can reduce the screen resilience of spring assembly in hinge movement process, for the initial screen resilience impact of hinge, still can not eliminate.As can be seen here, all poor with stability and the reliability in spring hinge when operation of cushion dashpot at present.Moreover, existing spring reset, in the hinge of cylinder buffer formula, the elastic force that spring produces in running is certain, so when cabinet door is when closing, the inertia effects that is subject to spring force and cabinet door, the speed of closing the door can be accelerated gradually, thereby finally cause cabinet door and cabinet to occur to clash into, produces noise.For addressing this problem, in existing technology, all adopt increasing damping to solve, but strengthening damping meeting cause the starting stage speed of cabinet door when closing excessively slow, affects efficiency.Therefore be necessary existing buffering reset hinge to be further improved.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is made to concrete further instruction.The automatic buffer reset hinge of cabinet door use for a kind of furniture, comprise the hinged hinge cup 1 of order successively, linking arm 2 and base 3, on hinge cup 1, U-shaped latch 4 is housed, one end of linking arm 2 is loaded on the upper arm 41 of U-shaped latch 4, the other end of linking arm 2 is movably hinged and is arranged on base 3 by link arm pin 21, the lower arm 42 of U-shaped latch 4 is movably articulated in the front end of duplicated crank 5 in hinge cup 1, the middle part of duplicated crank 5 and afterbody are respectively equipped with the first hinge hole 51 and the second hinge hole 52, the first hinge hole 51 is movably hinged with base 3 by the first bearing pin 53, the second hinge hole 52 is hinged with movable rocker arm 6 by the second bearing pin 54, it is characterized in that: in described base 3, be also provided with torsion spring 7, the fixing feet 71 of torsion spring 7 is by being pressed in the base plate of base 3, the movable leg 72 of torsion spring 7 is by being pressed on the deflector of being located on duplicated crank 5 leading portion sidewalls, deflector arranges away from the first hinge hole 51 places, spring force forces deflector to drive the front end of duplicated crank 5 to be upturned, realize the automatic buffer reset function of hinge.Spring force presses on duplicated crank, can produce precompression thereon, and when cabinet door is closed, precompression can keep cabinet door closely to close.In cabinet door open-type, precompression keeps duplicated crank and movable rocker arm in equilibrium state, makes cabinet door in normally open.
Described deflector is the roller bearing 8 being installed in rotation on duplicated crank sidewall, and the movable leg 72 of described torsion spring 7 is by being pressed in this roller bearing (8) surface.When duplicated crank moves, roller bearing rolls on the movable leg of torsion spring, can reduce friction factor, when increasing the service life, makes hinge close and open more smooth and easy.
Described deflector is the boss 9 being arranged on duplicated crank sidewall, on described torsion spring 7, is set with slide block 91, and slide block is provided with spigot surface 92 outward by being pressed in the deflection end of boss 9.
Described boss 9 is provided with deflection hole 93 and locating hole 94, and locating hole 93 snares are on the first bearing pin 53, and locating hole 94 is fixed on duplicated crank 5 by shop bolt.
The front end face of described boss 9 is circular-arc, between front end face and side by arc transition.
In described boss 9, be provided with through hole, the movable leg 72 of torsion spring 7 is arranged in this through hole.
Described deflector and torsion spring 7 are provided with two covers, and symmetry is arranged on duplicated crank 5 both sides.The installation quantity of selecting deflector according to the model size of hinge, small-sized hinge can monolaterally assemble, and large-scale and heavy hinge is selected bilateral assembling.
Operating principle: when cabinet door/hinge is closed, beat along with duplicated crank, distance between deflector and fulcrum of spring is pulled open gradually, so the stress point of spring on duplicated crank can slide from the one end near fulcrum of spring to the one end of departing from fulcrum of spring gradually, according to lever principle, the pressure that spring is applied on duplicated crank reduces the acceleration being produced with balancing tank door inertia gradually, makes cabinet closing speed stable and uniform.Avoided conventional hinge unstable because of constant stressed the caused door closing speed of spring, cause the closing the door too fast collision causing of tip speed and noise, therefore this programme can extensively be promoted the use of.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and manual, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications; as the mechanism of Deflector block, the arranging etc. of torsion spring, these changes and improvements all fall within the scope of claimed the utility model.
