In shape cavity, spiral groove is opened up on the rotary core, spring is fixedly installed on the middle part.
Further, the middle part includes including annular capping, sealed step and annular groove, institute under upper successively
It states annular capping to match with the open end of outer barrel, spring is fixedly installed in the sealed step, the top of the spring is fixed
Spacing ring is set, and sealing is fixedly installed in the inner wall and the outer wall of the annular groove and inner cylinder of the annular groove and outer barrel
Circle.
Further, the outer diameter of the annular capping is equal with the outer diameter of the outer barrel.
Further, the external stability setting locating piece of the outer barrel.
Further, the viscous fluid is silicone oil.
With the above structure, the utility model has the beneficial effect that：The utility model is rational in infrastructure, by rotary core viscous
Property fluid in rotation, viscous fluid to rotary core generate damping force, can not only due to the spiral groove that offers of rotary core
Make more viscous fluids can be housed in annular housing, increase damping force of the viscous fluid to rotary core, and spiral groove
The position of protrusion can also increase resistance so that damping gets a promotion, while can increase housing and rotor using spring
Between resistance so that damping gets a promotion.

Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
Embodiment, the present invention is further described in detail.It should be appreciated that the specific embodiments described herein are only used
To explain the utility model, it is not used to limit the utility model.
Referring to Fig. 1-3, a kind of rotary damper, including housing 1 and rotor 2, housing 1 include outer barrel 11 and coaxial arrangement in
Inner cylinder 12 in outer barrel 1 is surrounded by annular housing 13,13 built-in toughness fluid 3 of annular housing between outer barrel 11 and inner cylinder 12；
Rotor 2 is rotatablely connected with housing 1, including tubular rotary core 21, the middle part 22 being connected with rotary core 21 and with centre
The connected connecting portion 23 in portion 22, rotary core 21 are inserted in annular housing 13, and spiral groove 24, middle part are opened up on rotary core 21
Spring 25 is fixedly installed on 22.Spiral groove 24 is offered on rotary core 21, can not only make be equipped in annular housing 13
More viscous fluids 3 increase damping force of the viscous fluid 3 to rotary core 21, and the position of 24 protrusion of spiral groove also can
Enough increasing resistance so that damping gets a promotion, while can increase the resistance between housing 1 and rotor 2 using spring 25,
So that damping gets a promotion；Connecting portion 23 is mountable in the cover of automobile handrail box, and rotor 2 is connect with cover,
When being turned on and off cover, cover drives rotor 2 to rotate.
In the present embodiment, middle part 22 includes including annular capping 221, sealed step 222 and annular under upper successively
Groove 223, annular capping 221 are matched with the open end of outer barrel 11, and spring 25, spring 25 are fixedly installed in sealed step 222
Top fixed setting spacing ring 224, the inner wall and the annular groove 223 of annular groove 223 and outer barrel 1 are outer with inner cylinder 12
Sealing ring 4 is fixedly installed in wall.Two sealing rings 4 seal annular housing 24, it is therefore prevented that the leakage of viscous fluid 3.
In the present embodiment, the outer diameter of annular capping 221 is equal with the outer diameter of the outer barrel 11.When rotor 2 is inserted into housing 1
Afterwards, annular capping 221 is covered on the open end of outer barrel 11 just, prevents extraneous dust from entering in housing 1.
In the present embodiment, the external stability setting locating piece 14 of outer barrel 11.Housing 1 is installed on by automobile by locating piece 14
On the ontology of armrest box, then by the connecting portion 23 of rotor 2 rotor 2 is connected with the cover of automobile handrail box, you can realize lid
The rotation of body.
In the present embodiment, viscous fluid 3 is silicone oil.The viscosity of viscous fluid 3 is bigger, and the damping force of generation is bigger, cover
Movement is slower.The cover of different weight should select the viscous fluid 3 of different viscosity, to prevent since cover is overweight, viscosity
The damping force that small fluid generates is insufficiently resistant to cover dead weight and is violently closed cover；Or it prevents due to cover mistake
Gently, the damping force that tough fluid generates to be turned on and off cover excessively slow.
The operation principle of the utility model：When the rotary damper of the utility model is installed, first into annular housing 13
Appropriate viscous fluid 3 is injected, and rotor 2 is inserted into housing 1 and is rotatablely connected with it, then by locating piece 14 by housing 1
It is installed on the ontology of automobile handrail box, finally, by the connecting portion 23 of rotor 2 by the cover phase of rotor 2 and automobile handrail box
Even；When being turned on and off cover, cover drives rotor 2 to rotate, so that the viscosity in its rotary core 21 stirring annular housing 13
Fluid 3 generates shearing force, so as to which viscous fluid 3 forms damping force to rotary core 21, slows down the velocity of rotation of rotor 2, simultaneously
Since rotary core 21 offers spiral groove 24, make more viscous fluids 3 can be housed in annular housing 13, increase viscous flow
Body 3 further increases damping force, improves the damping of rotary damper so that cover to the damping force of rotary core 21
It can be slowly turned on and off.
The above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, those of ordinary skill in the art couple
The other modifications or equivalent replacement that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope should all cover in the right of the utility model.
