Embodiment 1
[0026] In embodiment one, if 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, and the second hinge 2 is provided with a rotating shaft 4, and the rotating shaft 4 can Rotationally installed in the mounting hole 3, the shaft 4 is provided with a screw 5, the first hinge 1 is equipped with a circumferentially fixed nut 6, the screw 5 and the nut 6 form a thread pair, the The nut 6 can slide axially along the rotating shaft 4 , and the first hinge 1 is installed with an elastic member 7 that prevents the nut 6 from sliding. Embodiment 1 The relative rotation of the hinge is converted into the axial movement of the nut 6, and the elastic force of the elastic member 7 on the nut 6 is used to achieve the effect of damping the hinge. On the other hand, the elastic member 7 acts behind the nut 6, and the nut 6 It cannot drive the screw rod 5 and the rotating sh...
Embodiment 2
[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.
Embodiment 3
[0031] In the third embodiment, as shown in 6, elastic members 7 are installed at both ends of the nut 6 in the limiting hole 9; in the fourth embodiment, as shown in 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 respectively provided with accommodating bins 8 , nuts 6 and elastic members 7 . The functions of the third embodiment and the fourth embodiment are the same, and both are for maintaining damping when the first hinge 1 and the second hinge 2 rotate relative to each other in different directions.
