Abstract
The utility model relates to a damping rotating shaft, the rotating shaft can be broadly used for connection part between rotational parts and base, the connection part comprises rotating shaft and shaft sleeve, wherein the polygon resilient sleeve is arranged between connection of rotating shaft and shaft sleeve, the open groove is arranged along axial direction for elastic metal material. The raised coaxial circle cambered surface arranged evenly along axial direction on central portion of polygon resilient sleeve, so the certain of wear is also between rotating shaft and shaft sleeve, but the radial force of polygon resilient sleeve is remain stationary, namely the damping force between rotating shaft and shaft sleeve can be automatically compensated, the service life of damping rotating shaft is greatly prolonged, the interlocked parts require to be opened and stopped on any position. The structure has the advantages of being simple, reliable, small and in light weight.
Description
Technical field
The utility model relates to a kind of Damping rotation shaft, is the connecting element that is widely used between parts that needs rotate and the matrix specifically.
Background technique
Damping rotation shaft is as connecting element, be widely used in the connecting element of image display screen and fuselage in notebook computer, digital image device and the portable DVD player machine, and the connecting element etc. of extendable swivel antenna and base among the GPS, it can make liquid crystal display panel, be parked in when antenna is opened on any position.Current, generally adopt the drive fit structure of rotating shaft and axle sleeve, employing is also arranged at rotating shaft end fluting, and make the rotating shaft spreading with screw, increase the structure of frictional damping.But the problem of this class rotating shaft maximum is that the life-span is low, because through after long-term the use, because fretting wear, damping force weakens, the damping force between axle and the axle sleeve is compensation not, thereby does not reach the effect of stopping in any position.Reach the purpose that increases damping though a kind of structure in back can be adjusted, hell to pay is adjusted in dismounting.
The model utility content
The utility model provides a kind of simple in structure in order to overcome the defective of prior art, can compensate the Damping rotation shaft of the damping force between rotating shaft and the axle sleeve automatically.
The utility model Damping rotation shaft comprises rotating shaft and axle sleeve, wherein is set with the polygonal resilient sleeve between the annular spaces that rotating shaft and axle sleeve are connected.
The utility model Damping rotation shaft is wherein in the faceted pebble center portion of polygonal resilient sleeve, along the coaxial circles cambered surface that is equipped with on the axial direction to outer lug.
The utility model Damping rotation shaft, wherein the polygonal resilient sleeve is provided with opening slot vertically.
The utility model Damping rotation shaft, wherein the section of polygonal resilient sleeve is positive 5～8 limit shapes.
The utility model Damping rotation shaft, wherein the polygonal resilient sleeve is for to be made by the metallic elastic material.
The utility model Damping rotation shaft since in rotating shaft and gap that axle sleeve is connected suit rubber-like polygonal resilient sleeve, therefore in use for some time, though wearing and tearing are also arranged between rotating shaft and the axle sleeve, but the radial force of polygonal resilient sleeve remains unchanged, promptly can compensate the damping force between rotating shaft and the axle sleeve automatically, thereby prolong the working life of Damping rotation shaft widely, making it interconnective parts need often open and firmly stop in any position, it is simple and reliable for structure, and volume is little in light weight.
Description of drawings
Fig. 1 is the utility model Damping rotation shaft STRUCTURE DECOMPOSITION principle schematic (solid);
The structural representation (wherein upper shaft sleeve defaults) that Fig. 2 installs for the utility model Damping rotation shaft;
Fig. 3 is for being provided with the polygonal resilient sleeve structural representation to the arc surface of outer lug in the utility model Damping rotation shaft.
Embodiment
By Fig. 1 and Fig. 2 as seen, the utility model Damping rotation shaft comprises rotating shaft 1 and axle sleeve 2, wherein is set with polygonal resilient sleeve 3 between the annular spaces that rotating shaft 1 and axle sleeve 2 are connected.The section of this polygonal resilient sleeve 3 is regular pentagon or octagon, and is provided with opening slot 4 vertically, the wear part of being made by elastic sheet material.
Fig. 3 is the faceted pebble center portion at polygonal resilient sleeve 3, along the coaxial circles cambered surface 5 that is equipped with on the axial direction to outer lug.
When installing and using, the inwall suit of rotating shaft 1 one ends and sleeve 3, or equipped with arc surface 5; The outer wall of sleeve 3 and axle sleeve 2 one end suits, the other end of rotating shaft 1 and axle sleeve 2 maybe need display screen of opening etc. to fixedly connected with body respectively.In fact do not have opening slot on the regular polygon resilient sleeve, the diameter of rotating shaft is a bit larger tham the inscribed circle diameter of regular polygon, or is a bit larger tham the diameter of coaxial circles cambered surface 5, also can realize compensating automatically the purpose of the damping force between rotating shaft and the axle sleeve.
