Detailed description of the invention
As employed some vocabulary in the middle of description and claim to censure specific components.Those skilled in the art should
It is understood that hardware manufacturer may call same assembly with different nouns.This specification and claims are not with name
The difference claimed is used as distinguishing the mode of assembly, but is used as the criterion distinguished with assembly difference functionally.As logical
" comprising " mentioned in the middle of piece description and claim is an open language, therefore should be construed to " comprise but do not limit
In "." substantially " referring in receivable range of error, those skilled in the art can solve described in the range of certain error
Technical problem, basically reaches described technique effect.Additionally, " coupling " word comprises any directly and indirectly electric property coupling at this
Means.Therefore, if a first device is coupled to one second device described in literary composition, then representing described first device can direct electrical coupling
It is connected to described second device, or is indirectly electrically coupled to described second device by other devices or the means that couple.Description
Subsequent descriptions is to implement the better embodiment of the present invention, for the purpose of right described description is the rule so that the present invention to be described,
It is not limited to the scope of the present invention.Protection scope of the present invention is when being as the criterion depending on the defined person of claims.
Below in conjunction with accompanying drawing, the present invention is described in further detail, but not as a limitation of the invention.
Embodiment 1:
As Figure 1-Figure 4, a kind of multidiameter shaft is present embodiments provided, including bearing 1 and axle sleeve 2, described bearing 1 He
One end of axle sleeve 2 is provided with dismountable retainingf key 3, and the outer surface at described axle sleeve 2 is along the circumferential direction provided with many group grooves 4, this
Groove 4 in embodiment is 10 groups, certainly can set 4 groups of numbers of groove according to actual needs, and these 10 groups of grooves 4 are along axle sleeve 2 longitudinally
It is uniformly distributed, in described groove 4, lifting parts 5 and resetting means are set；Described lifting parts 5 are sealene triangle, one end
Being rotationally connected with described groove 4 side, the other end is flexibly connected with resetting means；One end of described resetting means and described lifting
Parts 5 are flexibly connected, and the other end is fixing with groove 4 side to be connected；Described lifting parts 5 are circular arc with resetting means junction
Shape；The surface that described lifting parts 5 contact with described bearing 1 is inclined-plane and is provided with occlusion screw thread 8, and this occlusion screw thread 8 is with described
The occlusion screw thread 8 of bearing 1 matches.
Resetting means in the present embodiment is high energy spring 6, naturally it is also possible to for the resetting means of other material, as long as symbol
Close lifting parts 5 when unloaded can reset.
Described bearing 1 center is provided with interior hexagonal and rotates slot 7.
Embodiment 2:
The present embodiment is Application Example, and it is being mainly that the appearance at bearing 1 is uniformly arranged that multidiameter shaft realizes reducing function
Lifting piece.Multidiameter shaft mainly includes bearing 1 (threaded) and axle sleeve 2 (outer bearing 1) two large divisions composition.Bearing 1 and axle
Set 2 between fixed by retainingf key 3, prevent rotate after, inside and outside between rotate, cause separation or function can not be realized.Retainingf key 3
Can dismantle, retainingf key 3 is that retainingf key 3, according to rear, make axle sleeve 2 and bearing 1 be integrated, will not produce before and after the diameter of axle changes
Relative motion.
Lifting parts 5 can be up and down centered by axle, and this part is fixed on axle sleeve 2, and the bottom of lifting parts 5 has individual
Intilted screw thread, and inner bearing 1 matches.When inner bearing 1 is according to screw thread rotation, screw thread and lifting parts 5
Occlusion screw thread 8 phase occlusion, owing to the screw thread of lifting parts 5 is not level, but slopes inwardly, causes along with threaded engagement is deep
The increasing of degree, lifting parts 5 are on the premise of centered by axle, and rear portion upwards lifting, the lifting parts 5 being evenly arranged while
Under effect, the diameter of bearing 1 is made to become big.The high energy spring 6 at rear portion, is when the diameter of axle becomes again original when, and bearing 1 is to opposite direction
During rotation, prevent activity jam, inconvenient activity, affect functional realiey, and utilize the elastic force of high energy spring 6 so that it is be retracted in axle
In the groove 4 of set 2, even if the overall high-speed motion of bearing 1, also will not throw away.
Interior hexagon rotates the setting of slot, for rotating stress point during inner bearing 1, facilitates bearing 1 and axle sleeve 2 to be engaged.
Compared with prior art, multidiameter shaft of the present invention, reach following effect:
The multidiameter shaft simple in construction of the application, easy to operate, it is not necessary to refill, also eliminate the process of rewinding, reduce
Cost；
The multidiameter shaft of the application is widely used, and cannot be only used for coiling paper, plastics or textile industry, it may also be used for its
It needs the product of curling.
Described above illustrate and describes some preferred embodiments of the present invention, but as previously mentioned, it should be understood that the present invention
Be not limited to form disclosed herein, be not to be taken as the eliminating to other embodiments, and can be used for other combinations various,
Amendment and environment, and can be in invention contemplated scope described herein, by above-mentioned teaching or the technology of association area or knowledge
It is modified.And the change that those skilled in the art are carried out and change are without departing from the spirit and scope of the present invention, the most all should be at this
In the protection domain of bright claims.
