Abstract

The utility model provides a torque force hinge used to connect a body and a cover body to make cover body conduct the open and close motion relatively to the body. The torque force hinge of the utility model comprises two shaft bodies respectively arranged on the body and the cover body and a shaft sleeve sheathed and connected with the two shaft bodies. The torque force hinge of the utility model can balance the change of the torque force caused by the change of the angle in the open or close process of the cover body to generate the stable torque force to prevent the damage of the hinge mechanism caused by the disproportion of the torque force to prolong the service life of the hinge mechanism.

Description

Torque force hinge joint

Technical field

The utility model relates to a kind of hinge, and particularly a kind of torsion that is produced when rotating in order to balance hinge is so that the Torque force hinge joint of hinge stable rotation.

Background technique

Existing hinge structure comprises an axis body, and is articulated in the sleeve on the axis body, and the center of axis body has a gap, when axis body is articulated in sleeve, makes the gap smaller of axis body and produces pressure, and then produce torsion.

But because this existing sleeve do not have elasticity, only depend on the gap elasticity of axis body and produce torsion, make it be easy to generate elastic fatique, and hinge torsion is reduced, and because of being subjected to the restriction in axis body gap, can't produce bigger torsion, so this kind hinge only is fit to use on the demand of low torsion.

Another existing hinge includes an axis body, and axis body has the axle that a junction and is connected to joint; And two rotating components, two rotating components have the circular arc sheet body that an external diameter size matches, the circular arc sheet body of a rotating component wherein can be arranged in the space of circular arc sheet body of another rotating component, and arbitrary circular arc sheet body has an opening slot, two rotating components respectively have a Fixed Division again, be arranged in by the circular arc sheet body of a rotating component wherein in the space of circular arc sheet body of another rotating component, the Fixed Division of two rotating components is a layered laminate, with two rotating components of above-mentioned composition and an axis body be individually fixed in a main body and desire the object of folding, when the object of folding that folding is desired, axis body produces relative rotation with two rotating components, but this structure is when continuing to rotate, its torsion also can raise, and easily causes the fracture of axis body.

The model utility content

Torsion when main purpose of the present utility model is the balance hinge rotation, to prevent the excessive damage that causes linkage of torsion, realized that by following structure this Torque force hinge joint comprises:

Two axis bodies, arbitrary axis body has a fixed block, and a pivot that is arranged in fixed block, is provided with a blocked part between fixed block and pivot;

One axle sleeve, it is open to be a hollow tubular and two ends, is worn by two ends of axle sleeve respectively in order to the pivot for above-mentioned two axis bodies.

Be arranged in two ends of above-mentioned axle sleeve by pivot with two axis bodies, and the fixed block of two axis bodies is individually fixed in a main body, and on the lid, when folding cover, wherein an axis body will begin to rotate, be fixed on another axis body with respect to axle sleeve,, impel this moment another axis body to begin to rotate, and be fixed in respect to axle sleeve on the axis body of former rotation greater than another axis body until the torsion that axis body produced that rotates, can not continue to raise with this torsion that axis body is rotated, cause damage.

Embodiment

Relevant detailed description of the present utility model and technology contents, existing accompanying drawings is as follows:

Seeing also Fig. 1, is profile schematic perspective view of the present utility model, and as shown in the figure, Torque force hinge joint of the present utility model comprises:

The isostructural axis body 11,12 of two-phase, it has one and is tabular fixed block 111,121, offer a plurality of perforation of using for lock member (not shown) bolt-lock 112,122 on the fixed block 111,121, be located at respectively on a main body (not shown) and the lid (not shown) for above-mentioned axis body 11,12; On above-mentioned fixed block 111,121, be equipped with a cylindrical pivot 113,123 respectively, and between fixed block 111,121 and pivot 113,123, be provided with a rounded tabular blocked part 114,124;

And an axle sleeve 13, it is open to be a hollow tubular and two ends, and in rotating mode, two ends by axle sleeve 13 wear respectively, replace two end end faces of axle sleeve 13 until the blocked part 114,124 of axis body 11,12 with the pivot 113,123 of above-mentioned axis body 11,12; Axle sleeve 13 has an elongated groove 131, when the pivot 113,123 of two axis bodies 11,12 is arranged in axle sleeve 13, axle sleeve 13 has the space that an elasticity struts, axle sleeve 13 has one in order to oil is imported the oil groove 132 with the pivot 113,123 of lubricated axis body 11,12, thereby make opening and closing movement more smooth and easy, constitute the structure of a Torque force hinge joint like this.

Torque force hinge joint of the present utility model passes through above-mentioned axis body 11,12 are hubbed at respectively on a main body and the lid, when starting lid, the pivot 123 of axis body 12 will rotate in axle sleeve 13, and produce a torsion, be fixed in axis body 11 on respect to axle sleeve 13 this moment, but when the pivot 123 of axis body 12 continues to rotate in axle sleeve 13, the torsion of axis body 12 will raise, until the torsion of axis body 12 during greater than the torsion of axis body 11, axis body 12 promptly stops operating, change by axis body 11 and begin to rotate, be fixed in axis body 12 on respect to axle sleeve 13 this moment, to prevent axis body 11,12 when rotating, and torsion continues to raise, and cause the damage of linkage, to reach the purpose of balance torsion.

See also Fig. 2,3, it is the generalized section of preferred embodiment of the present utility model and Fig. 2, as shown in the figure, include an axis body 11 identical with said structure, 12, and at its pivot 113,123 are provided with several circular scrobicular rings 115, and the axle sleeve 13 identical with said structure, and also increase by an anti-sliding sleeve 14, it is a hollow tubular and two ends are open, be arranged in the axle sleeve 13, wherein anti-sliding sleeve 14 offers one oppositely with respect to the groove 142 of the elongated groove 131 of axle sleeve 13, and it is a plurality of corresponding to pivot 113, the interior salient point 141 of 123 circular scrobicular ring 115, thus make axis body 11, during 12 rotations, interior salient point 141 can be along pivot 11, the track of 12 circular scrobicular ring 115 moves, and card only limits pivot 113,123 circular scrobicular ring 115 makes axis body 11,12 are difficult for breaking away from axle sleeve 13.
