The screw mandrel is arranged on the end of rotating shaft, and the end of first hinge is provided with receiving storehouse, the receiving storehouse If spacing hole, the nut is arranged in spacing hole, and the section of the spacing hole and the shaft section of nut match.

The elastic component is cylindrical spring, and one end of the cylindrical spring is contacted with nut, the other end and the bottom for accommodating storehouse Portion is contacted.

The cylindrical spring is concentrically mounted on the periphery of screw mandrel.

Thrust bearing is provided between the cylindrical spring and nut.

Two ends in the spacing hole in nut are mounted on elastic component.

The two ends of the rotating shaft are equipped with screw mandrel, and the two ends correspondence of first hinge is equipped with receiving storehouse, nut and bullet Property part.

The receiving storehouse and the first hinge are detachable.

The screw mandrel is self-locking trapezoidal thread with nut.

The beneficial effects of the utility model are：

The axial movement for being converted to nut of hinge is utilized elastic force of the elastic component to nut by the utility model To reach the effect of Damping hinge, another aspect elastic component is acted on after nut, and nut can not drive screw mandrel and axis of rotation, First hinge and the second hinge can keep any angle in the case where not acted on by external force, compared with existing Damping hinge, and function is more It is perfect, it is wider suitable for scope.

Embodiment

Below in conjunction with the accompanying drawings with embodiment, with reference to accompanying drawing, the utility model is described in further detail.

In embodiment one, as shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of Damping hinge, including the first hinge 1 and the second hinge 2, first hinge 1 sets mounting hole 3, and second hinge 2 sets rotating shaft 4, and the rotating shaft 4 is rotatably mounted in mounting hole 3, The rotating shaft 4, which is provided with screw mandrel 5, first hinge 1, is provided with circumferentially fixed nut 6, the screw mandrel 5 and the structure of nut 6 Into screw thread pair, the nut 6 can be provided with the elasticity for preventing nut 6 from sliding along the axial slip of rotating shaft 4 in first hinge 1 Part 7.Embodiment one by the axial movement for being converted to nut 6 of hinge, using elastic component 7 to the elastic force of nut 6 come The effect of Damping hinge is reached, another aspect elastic component 7 is acted on after nut 6, nut 6 can not drive 4 turns of screw mandrel 5 and rotating shaft Dynamic, the first hinge 1 and the second hinge 2 can keep any angle in the case where not acted on by external force, compared with existing Damping hinge, Function is more perfect, wider suitable for scope.

In embodiment one, as shown in Figure 1, Figure 2, Figure 3, Figure 4, the screw mandrel 5 is arranged on the end of rotating shaft 4, described first The end of hinge 1 is provided with receiving storehouse 8, the receiving storehouse 8 and sets spacing hole 9, and the nut 6 is arranged in spacing hole 9, described The section of spacing hole 9 and the shaft section of nut 6 match；The elastic component 7 be cylindrical spring, one end of the cylindrical spring with Nut 6 is contacted, and the other end is contacted with accommodating the bottom in storehouse 8；The cylindrical spring is concentrically mounted on the periphery of screw mandrel 5.Embodiment One structure, cylindrical spring provides damping when being rotated for hinge, is arranged on the cylindrical spring of the periphery of screw mandrel 5 and also has higher stabilization Property, it is ensured that after many tasks of hinge, remain to normal work.
