Abstract

The utility model discloses a composite hinge structure, which is mainly used for the opening and closing movement of two opposite objects; the opposite buckling parts are separately staggered on the opposite ends of the two swing parts and enable the two swing parts to be pivoted on the shaft through the buckling part; the shaft part is fixed on the fixed part, the two swing parts are fastened on the body to be opened by using the opposing movement of swing parts to set the two objects in motion; when a swing part swinging with stress, one of the buckling parts bears the external force, wherein one end is swung by the opening, but the other buckling part is still buckled the shaft part tightly and disables the shaft to move, thus the purpose can be reached that no swing can be generated when opening the two objects.

Description

Multiple chip hinge arrangement

Technical field

The utility model relates to a kind of hinge arrangement, and is particularly a kind of by two swing components are coupling on axle spare relatively and alternately, the multiple chip hinge arrangement of the stability when keeping hinge through.

Background technology

Hinge is used in the relative open and close movement of two articles, see also shown in Figure 1, existing hinge arrangement comprises: a fixture 13, one stator 15, and one utilize be coupling swing component 16 on axle spare 12 of buckling parts 17, force in during use on the swing component 16, and utilize the rotation relationship of angle that buckling parts 17 and the axle frictional force control buckling parts 17 between the part 12 folds and axle part 12, rotating manner has two kinds: one is that fixedly swing component 16 rotates with axle spare 12, another is that fixed shaft 12 is with swing component 16 rotations, yet, no matter use which kind of rotation mode, this structure can cause the consume of metal friction when rotating, because buckling parts 17 is circular-arc, when the application of force makes its rotation, one end of buckling parts 17 can be opened because of this power, because the swing component of one chip 16 is when back and forth using for a long time, it is tired more to be easy to generate metal, and cause a part 12 and the gap of buckling parts 17 to become big, thereby cause lid to launch or produce when folding rocking, or buckling parts 17 may produce fracture because of back and forth using, if and increase the intensity of hinge 1 ' buckling parts 17, then can reduce its elasticity, cause dimensional tolerance excessive to the torsion influence, make torsion be difficult for adjusting hinge 1 ', application life is also relatively poor; Relative buckling parts 17 intensity reduce, and then elasticity increases, but make the easy tired torsion that causes of metal descend.In addition, when the application of force makes buckling parts 17 rotations (application of force direction shown in arrow among the figure 18), one end of buckling parts 17 can be opened because of this power, frictional force reduces, and other direction (application of force direction shown in arrow among the figure 19) when rotation, buckling parts 17 can fit, and frictional force increases, thereby makes the torsion of hinge opening and closing inequality.

The utility model content

Stability when main purpose of the present utility model is to keep hinge through is mainly realized by following structure, and multiple chip hinge arrangement of the present utility model comprises:

Two swing components are respectively equipped with a buckling parts in the corresponding side of this two swing component, and this buckling parts is circular-arc and uniformly-spaced sets up and present concavo-convex state;

A part, an end and this buckling parts of this part join, and swing component can be rotated on axle spare, and the buckling parts on two swing components is the subtend pivot joint;

One fixture joins with the other end of axle spare, and this fixture is fixed in one to be desired on the folding object;

One sleeve, this sleeve are located between this buckling parts and this part, utilize the interference of buckling parts and axle part the frictional force between sleeve and this part to be provided and then to produce torsion.

Another purpose of the present utility model is to increase hinge strength, existing hinge is provided with a stator in a rotation section and a both sides of part joint, the rotation section that this stator is used for reducing existing hinge is when rotating and rocking of causing, but also gapped between this stator and the hinge, though shaking degree has the improvement effect to utilize the staggered mode that engages of buckling parts on two swing components and reduce the effect of rocking not as the utility model.

It is of the present utility model again when a purpose is to make hinge opening and closing, its torsion all equates, it is by articulating buckling parts subtend on two swing components, wherein a swing component reduces because of the buckling parts frictional force that is unlocked when stressed, and the buckling parts of another swing component is fited and frictional force is increased, the torsion when coming the balance hinge folding with this.

The specific embodiment

Relevant detailed description of the present utility model and technology contents now just cooperate graphic being described as follows:

See also Fig. 2, shown in 3, hinge is applied on the object that utilizes the mode folding that is coupling, hinge 1 is provided with first swing component 10 and second swing component 11, this first, second swing component 10, an end of 11 is provided with a buckling parts 100,110, utilize this buckling parts 100,110 can make this first,

second swing component

10,11 lock rings are on sleeve 26, but can rotate around sleeve 26, sleeve 26 is for hollow and annular and have a groove 27, the oil groove 28 that has an arc on it is in order to import oil, this sleeve 26 is arranged in a part 12 and buckling parts 100, between 110, in order to fixing buckling parts 100,110 and the axle part 12, on fixture 13, be provided with a groove 130 in addition, the other end of axle spare 12 is fixed in this groove 130, and this first, second swing component 10, establish a perforation 101 on 11,111, with this first, second swing component 10, perforation 101 on 11,111 utilize retaining element 14 to be fixed on the cap of object, and this retaining element 14 is screws, and this fixture 13 is fixed on the base of object.

In addition, first of hinge 1 of the present utility model, second swing component 10, buckling parts 100 on 11,110 all are uniformly-spaced and set up, and join with staggered and opposition mode, and be placed in earlier on the sleeve 26, be coupling again on axle spare 12, to need not make like this and be used for the stator 15 of stable oscillation spare 16 on the existing hinge 1 ' (seeing also Fig. 1), in addition, the utility model can be for being returned to the hinge of origin-location, promptly add a spring (not shown) on axle spare 12, this spring makes hinge 1 after stressed doing relative motion, and can return back to the origin-location, or can be for be not fixed on the fixture 13 hinge free to rotate at axle spare 12.

See also Fig. 4-1, shown in the 4-2, when hinge 1 is subjected to a upward force, first swing component 10 is upwards passed, buckling parts 100 on first swing component 10 is subjected to interlock and separates with axle spare 12 at this moment, produce the phenomenon that gap 2 is strengthened slightly, this gap of strengthening slightly 2 is caused to produce between first swing component 10 and the axle part 12 and is rocked, also can reduce frictional force, but when this upward force acts on second swing component 11, second swing component 11 is also upwards passed, and rotations of being taken advantage of a situation of the buckling parts 110 of second swing component 11, buckling parts 110 can more fit with a part 12, can not cause the increasing slightly in gap 2, thereby can be tightr, so no matter this hinge 1 rotates up or down, can not produce and rock, but also balance two buckling partss 100, frictional force between 110 makes hinge 1 no matter open or close its torsion and all equates.
