As preferred：The limit assembly includes the rigidity rotation block of two arcs being oppositely arranged and is filled in two
The size of elastic deformable body between rigidity rotation block, the rigidity rotation block is gradually reduced from one end to the other side, the rigidity
The larger one end of moving block is installed in rotation on by axis pin on the first rotatable parts.Using the above structure, turned by rigidity
Motion block is rotated along axis pin, realizes that the size of limit assembly is variable.
As preferred：The width of annular groove between every piece of rigidity rotation block and the pedestal from rigidity rotation block compared with
Big one end is gradually reduced to smaller one end.Using the above structure, make the damping action variation that the second rotatable parts are subject to more
Ledger line, damped motion are more steady.
As preferred：The mechanism that stretches into includes mounting post, and one end of the mounting post is fixedly connected with the mounting base, separately
One end is equipped with sliding equipment.Using the above structure, make sliding of second rotatable parts in annular groove by the way that sliding equipment is arranged
It is more smooth.
As preferred：The sliding equipment is ball, and ball can be limited in the end face of the mounting post by the mounting post
On.Using the above structure, it has the advantages of simple structure and easy realization, it is of low cost.
As preferred：The elastic deformable body is rubber material, and Nian Jie with the rigidity rotation block.Using the above knot
Structure has the advantages of simple structure and easy realization, of low cost.
As preferred：First rotating shaft is equipped on a side end face of first rotatable parts far from the annular groove to install
Hole is equipped with the second shaft mounting hole on the side end face that the mounting base stretches into mechanism far from described in.Using the above structure, just
In the installation and use of the present invention.
Compared with prior art, the beneficial effects of the invention are as follows：
It is simple in structure, novel using single direction rotation damper provided by the invention, it is easy to accomplish, production is of low cost, and easily
In assembly, mitigate the labor intensity of worker, effectively increase production efficiency, while state dampened being kept not make for a long time
At its damping can be made to decline, use reliability is high.

Specific implementation mode
The invention will be further described with attached drawing with reference to embodiments.
As shown in Figure 1, Figure 2 and Figure 3, a kind of single direction rotation damper, including the first rotatable parts 1 of coaxial arrangement and
Two rotatable parts 2, first rotatable parts 1 include pedestal 12, and the upper surface of the pedestal 12 is equipped with groove, is set in the groove
It is equipped with the variable limit assembly 13 of size, which is located at the middle part of the pedestal 12.
As shown in Figures 2 and 3, the rigidity rotation block 131 of the limit assembly 13 including two arcs being oppositely arranged with
And it is filled in the elastic deformable body 132 for the rubber material being mutually bonded between two rigidity rotation blocks 131, the rigidity rotation block
131 size is gradually reduced from one end to the other side, the larger one end of the rigidity rotation block 131 by axis pin 3 rotationally
On the first rotatable parts 1, two rigidity rotation blocks 131 are identical, total together with elastic deformable body 132, axis pin 3
With composition " Tai Ji " shape.There are gaps between the rigidity rotation block 131 and the pedestal 12, constitute annular groove 11, annular
The width of slot 11 is gradually reduced from the larger one end of the same rigidity rotation block 131 to smaller one end.
Fig. 1, Fig. 4 and Fig. 5 are referred to, second rotatable parts 2 include the mounting base 22 of cylinder and are arranged at this
Mechanism 21 is stretched into two faces setting of insertion annular groove 11 on 22 lower face of mounting base, and stretching into mechanism 21 can be along the ring
Shape slot 11 slides, which is less than or equal to the maximum width of the annular groove 11, and is more than
The minimum widith of the annular groove 11.The mechanism 21 that stretches into includes mounting post 211, one end of the mounting post 211 and the peace
Dress seat 22 is fixedly connected, and the other end is equipped with sliding equipment 212, which is ball, and the mounting post 211 can incite somebody to action
Ball is limited on the end face of the mounting post 211, and therefore, this is dynamic for rotation of second rotatable parts 2 on the first rotatable parts 1
Make the rolling by the ball in mounting post 211 in annular groove 11 to complete.
Fig. 1, Fig. 3 and Fig. 4 are referred to, is set on a side end face of first rotatable parts 1 far from the annular groove 11
There is first rotating shaft mounting hole 14, being equipped with the second shaft on the side end face that the mounting base 22 stretches into mechanism 21 far from described in pacifies
Hole 23 is filled, in order to the installation and use of this single direction rotation damper.
The course of work of the present invention is as follows：
The first rotating shaft mounting hole 14 of the present invention and the second shaft mounting hole 23 are connected with driving the device of the invention respectively
It connects, the second rotatable parts 2 of the invention can only be from the same rigidity rotation block 131 relative to the rotation direction of the first rotatable parts 1
Rotation is gradually reduced to smaller one end in larger one end, i.e. the second rotatable parts 2 can only be such as figure relative to the first rotatable parts 1
2 rotate clockwise.When two, which are stretched into mechanism 21, is located at width and is more than itself one section of annular groove 11, dampened land used can not be made
Sliding；When two, which are stretched into mechanism 21, is located at width positioned at one section of annular groove 11 for being less than itself, the effect of device driven is stretched
Enter mechanism 21 to squeeze rigidity rotation block 131 to the center of circle direction of limit assembly 13, the rotation of rigidity rotation block 131 and elasticity of compression change
Body 132, annular groove 11 broaden, and stretch into mechanism 21 and are passed through；Mechanism 21 is stretched into when two leaves width positioned at less than itself
One section of annular groove 11 after, two are stretched into that mechanism 21 is not dampened again to make land used sliding, and elastic deformable body 132 makes rigidity rotation
Block 131 resets.Second rotatable parts 2 and the first rotatable parts 1 constantly relatively rotate, constantly repeatedly abovementioned steps.
Finally, it should be noted that foregoing description is only the preferred embodiment of the present invention, the ordinary skill people of this field
Member under the inspiration of the present invention, without prejudice to the purpose of the present invention and the claims, can make table as multiple types
Show, such transformation is each fallen within protection scope of the present invention.
