Embodiment
Rotary part butt among the utility model embodiment in elastic component and the rotary component, the power that when rotary part rotates, is squeezed generation elastic strain, and under the spring-back force effect, produce damping, spacing to rotary part.The utility model embodiment relies on the spring-back force of elastic component spacing to rotary part, and it is spacing to rotary part to be different from the frictional force according between axle and the axle sleeve shown in Figure 1.Elastic component among the utility model embodiment can not use because of repeated multiple times and lose efficacy, and is not easy to wear more, and not high to dimension precision requirement.
Referring to Fig. 2, the hinge in the present embodiment comprises sheath 201, rotary component 202 and elastic component 203.Wherein rotary component 202 comprises joint 2021 and rotary part 2022.Joint 2021 is one-body molded with rotary part 2022.
Sheath 201 is used for being fixedly connected with external equipment, so that hinges fixing fixes on the external equipment 204, referring to shown in Figure 3.Joint 2021 is rotationally connected with sheath 201, and rotary part 2022 can be around sheath 201 rotations.Elastic component 203 is connected to the rotary part 2022 in sheath 201 and the rotary component 202, the power generation elastic strain that when rotary part 2022 rotations, is squeezed, and under the spring-back force effect, produce damping, spacing to rotary part 2022.
Preferable, sheath 201 is the semi-surrounding structure, elastic component 203 is positioned at sheath 201, referring to shown in Figure 4.Effectively fixedly elastic component 203, and are convenient to assembling.Sheath 201 has semi-circular hole 2011, is used for fitting in axle with joint 2021, is rotationally connected so that realize.
Preferable, elastic component 203 comprises breach 2031, when being squeezed power to the direction generation elastic strain of dwindling breach 2031.Adopt this structure, the abrasion resistance of elastic component 203 is better, is suitable for long-term use.And elastic component 203 is a circular arc at rotary part 2022 rotary courses and rotary part 2022 butt places.This structure can make elastic component 203 spacing to rotary part 2022 in arbitrary position in the whole rotary course of rotary part 2022.Preferably, elastic component 203 is a C type spare, referring to shown in Figure 5.Especially, said circular arc is concentric with the rotating locus of rotary part 2022, makes the spring-back force of elastic component 203 affact rotary part 2022 as much as possible, reduces the power that leaks.
