Example Embodiment

[0026] In the first embodiment, such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a damping hinge includes a first hinge 1 and a second hinge 2, the first hinge 1 is provided with a mounting hole 3, the second hinge 2 is provided with a rotating shaft 4, and the rotating shaft 4 can be Rotatingly mounted in the mounting hole 3, the rotating shaft 4 is provided with a screw rod 5, a circumferentially fixed nut 6 is mounted in the first hinge 1, and the screw rod 5 and the nut 6 constitute a threaded pair. The nut 6 can slide axially along the rotating shaft 4, and an elastic member 7 is installed in the first hinge 1 to prevent the nut 6 from sliding. In the first embodiment, the relative rotation of the hinge is converted into the axial movement of the nut 6, and the elastic force of the elastic element 7 on the nut 6 is used to achieve the effect of damping the hinge. On the other hand, the elastic element 7 acts on the nut 6, and the nut 6 parallels The screw rod ...

Example Embodiment

[0030] In the second embodiment, as shown in 5, a thrust bearing 10 is provided between the cylindrical spring and the nut 6. The thrust bearing 10 in the second embodiment can avoid relative sliding between the cylindrical spring and the nut 6 and can make the whole device more stable.

Example Embodiment

[0031] In the third embodiment, as shown in 6, the limiting hole 9 is equipped with elastic members 7 at both ends of the nut 6; in the fourth embodiment, as Figure 7 As shown, both ends of the rotating shaft 4 are provided with screw rods 5, and both ends of the first hinge 1 are provided with a receiving bin 8, a nut 6 and an elastic member 7 correspondingly. The function of the third embodiment is the same as that of the fourth embodiment, both of which are to maintain damping when the first hinge 1 and the second hinge 2 are relatively rotated in different directions.

Abstract

The invention discloses a damping hinge. Any included angle can be maintained for the damping hinge. The invention provides the damping hinge without a reverse initiative acting force. The damping hinge comprises a first hinge and a second hinge. A mounting hole is formed in the first hinge, a rotary shaft is arranged on the second hinge, the rotary shaft is rotatably mounted in the mounting hole, a lead screw is arranged on the rotary shaft, a circumferentially fixed nut is mounted in the first hinge, the lead screw and the nut form a thread pair, the nut can axially slip along the rotary shaft, and an elastic piece which prevent slippage of the nut is mounted in the first hinge. According to the damping hinge disclosed by the invention, relative rotation of the hinges is converted into axial movement of the nut, and the effect of the damping hinge is achieved by virtue of an elastic force of the elastic piece to the nut. On the other hand, the elastic piece acts on the nut which cannot drive the lead screw and the rotary shaft to rotate, and the first hinge and the second hinge can be maintained at any angle without an external force. Compared with an existing damping hinge, the damping hinge disclosed by the invention is more perfect and wider in application range.

Description

technical field [0001] The invention relates to the field of hardware, in particular to a damping hinge. Background technique [0002] The patent with the authorized notification number CN205654209U discloses a damping hinge structure. In the above structure, a torsion spring is arranged on the door shaft between the first hinge and the second hinge, and the two ends of the torsion spring are respectively limited. , in the opening and closing process of the first hinge and the second hinge, both will drive the door shaft to rotate, thereby compressing or stretching the torsion spring, and through the reaction force of the torsion spring, it will play a role in controlling the first hinge and the second hinge. The cushioning effect of the opening and closing action of the two hinges. [0003] The torsion spring in the above patent has been interacting with the first and second hinges. When there is no external force, the first and second hinges will maintain a specific angle...
