Embodiment
Below in conjunction with the attached drawing in the utility model, the technical solution in the utility model is carried out clearly and completely
Description, it is clear that described is only the utility model part of the embodiment, instead of all the embodiments.Based on this practicality
Embodiment in new, shall fall within the protection scope of the present invention.
As depicted in figs. 1 and 2, a kind of shaft of no axle sleeve, includes connecting shaft 1, torsional spring setting-up piece 7, torsional spring 6, tablet
Gasket 4, fixed frame 5, links up with gasket 3, butterfly gasket 2, locking member 1.As shown in figure 3, connecting shaft includes fixing end 12 and stretches out
13 are held, includes fixed part in fixing end, for being connected with other main bodys, external part is flat shape shaft, is set on external part 13
Screw thread is equipped with, a step 9 is additionally provided with external part 13.One is provided between the fixing end 12 of connecting shaft and torsional spring 6
A torsional spring setting-up piece, the torsional spring setting-up piece 7 have a centre bore, and the shape of centre bore is non-circular, it is preferred that centre bore
Shape it is similar to the cross section of the connecting shaft external part 13, and size is so that the external part 13 of connecting shaft can wear just
Cross, it is therefore intended that when flat axis pass through torsional spring setting-up piece 7 centre bore when, prevent between torsional spring setting-up piece 7 and connecting shaft 8 into
Row relatively rotates.A notch is contained in the both sides of the centre bore of torsional spring setting-up piece 7, which has various shapes, example
Such as, can be that rectangle can also be semicircle, one of free end that the notch is used to limit torsional spring moves radially, if
The purpose for putting two notches be in order to assembling when being capable of fool proof.As shown in figure 4, fixed frame 5 is included in the side towards shaft
There is centre bore, also include a location hole 11, which is used for the one of free end for fixing torsional spring.In fixed frame 5
A side wall on contain a notch 10.The notch 10 is engaged to form a position limiting structure with linking up with the lug boss of gasket,
Butterfly gasket 2 is used for the pretightning force of pivot structure, and locking member is used for and the screw-threaded coupling on the external part of connecting shaft 8, the locking
Part can be nut.
The external part of connecting shaft 8 sequentially passes through torsional spring setting-up piece 7, and torsional spring 6, flat gasket 4, links up with gasket 3, butterfly pad
Piece 2, locking member 1, one of free end of torsional spring 6 are fixed in one of notch of torsional spring setting-up piece 7, another is certainly
Be fixed on by end in the location hole on fixed frame 5, the step of 8 external part of connecting shaft is against on flat gasket, prevent connecting shaft 8 to
Axial displacement occurs for fixed frame 5.As shown in figure 5, in the pivot structure containing axle sleeve, connecting shaft 8 is prevented using axle sleeve 14
Axial displacement occurs to fixed frame 5；Flat gasket 4 is equipped between the step and fixed frame of connecting shaft 8, for increase step with
The contact area of fixed frame 5, fixed frame 5 and hook gasket 3 between also be provided with flat gasket 4, for increase hook gasket with
Contact area between flat gasket, the position gasket can also be accepted or rejected according to requirements for life, and hook gasket 3 is convex comprising one
Structure is played, which is stuck in the notch of fixed frame 5, when connecting shaft 8 rotates so that hook gasket is not with connecting shaft
8 rotation and rotate.Several dish-like gaskets 2 are equipped between locking member 1 and hook gasket, certain pretension can be provided
Power, the quantity of the dish-like gasket 2 can be 1, or multiple.
During connecting shaft is rotating, torsional spring can not only be relied on to provide moment of torsion, moreover it is possible to by the step of connecting shaft with putting down
Frictional force between plate gasket 4 provides moment of torsion.
