Abstract
The utility model relates to a rotating shaft structure combined by a support, a fulcrum, a linking member, a primary elastic device, an end sealing member, a secondary elastic device and a rotating member. When an axis rotating member rotates, axial friction is formed between the slice convex of the linking member and the support convex of the support. Only when the slice convex and the support convex respectively fall into a support concave and a slice concave does torque force release, while the rear block margin of the rotating member bunts the movable end of the elastic device to rotate, so the secondary elastic device fastens the shaft rod of the fulcrum. When the elastic fastening force of the secondary elastic device is released, the rotating member is opened with an angle and the slice convex and the support convex have an axial friction.

Embodiment
To shown in Figure 2, basically, rotating shaft of the present utility model is by a support 1, one fulcrum 2, one coupling components 3, one first elastic devices 4, one end sealings 5, one second elastic devices 6, and single-revolution spare 7 combines as Fig. 1.
Wherein, support 1 is a support body, and its top tool one axis hole 11 passes through for fulcrum 2, and periphery annular the be crisscross arranged frame protruding 12 of tool height fall and frame in one side is recessed 13, and these axis hole 11 belows extend a trip 14, and side direction is opened a positioning hole 15.In addition, this support 1 below then laterally or longitudinal extension a junction 16, at least one hole 17 that connects is opened on its surface, for conjunction, for example screw passes through, and in conjunction with article, for example main body portion.
Wherein, this is put oil ring 26 central, circular annular distance 26a and passes through for jack-post 21, opens running through of some oilhole 26b on its anchor ring, supplies the ccontaining of lubricant grease, so that effect lubricated and the different sound of elimination to be provided.
Coupling component 3 is a lamellar body or block, and its company hole of offering 31 is passed through for jack-posts 21, and interlock with it.With respect to this protruding 12 and recessed 13 positions of frame tool height fall sheet recessed 32 and sheet protruding 33 then are set, with sheet protruding 33 along protruding 12 displacements of frame, can form axial rub torsion, only moved to frame at recessed 13 o'clock, then because of this height fall factor, and fall in the frame recessed 13, this sheet recessed 32 also engages with frame protruding 12 simultaneously, forms a torsion releasing effect according to this.Moreover, before then forming one respectively, end coupling component 3 peripheries only edge 35 of an edge 34 and a back, to touch trip 14, with restriction as the folding angle by the forward and backward edge that ends.
Revolving meber 7 is to be a support body, and it axially offers a convergence hole 71, and for being connected with axostylus axostyle 24, the outer radial of this convergence hole 71 forms an arc recess 72, and its front and back ends respectively has a forward and backward retaining edge 73 and 74 of one's own.Wherein, the movable end 62 of this second elastic device 6 is to be placed in arc recess 72, therefore, this revolving meber 7 is when turning down, can suppress and promote second elastic device 6 downwards, so that it tightens axostylus axostyle 24, the pivoted pole 75 that revolving meber 7 sides extend then can link with a body of rod, to be connected with display unit in the cover body part.
As shown in Figure 3, rotating shaft of the present utility model is when operation, when cover body part is outwards raised, revolving meber 7 is together with the i.e. outwards revolution of fulcrum 2, this moment, the sheet protruding 33 of coupling component 3 promptly moved along frame protruding 12, torsion is resulted between the two, and the movable end 62 of second elastic device 6 then moves to back stopping edge 74 along arc recess 72.When this cover body part is in erectility as Fig. 3.At this moment, if with rotating shaft outwards revolution again, sheet protruding 33 prop up trip 14 up to ending edge 35 thereafter, and the movable end 62 of this second elastic device 6 also props up front stopping edge 73, is the limit of ending of raising this moment along protruding 12 displacements of frame at this moment.
As shown in Figure 4, as when desiring to cover, only must get final product by reverse operating, at this moment, it is to prop up trip 14 that coupling component 3 preceding ends edge 34, and the movable end 62 of back stopping edge 74 compactings second elastic device 6, and make it tighten axostylus axostyle 24.At this moment, it is recessed 32 that sheet protruding 33 and frame protruding 12 fall into frame recessed 13 and sheet respectively, makes torsion be releasing state, and the weight of cover body part is then supported by this second elastic device 6, and under the unlikely bob, cover body part and main body portion then can be by existing fastener snappings.
As shown in Figure 5, after the fastener between cover body part and main body portion was opened, the power of tightening of second elastic device 6 promptly discharged, and made movable end 62 promptly promote back stopping edge 74 and also raised an angle slightly, and the user can raise cover body part easily, and sharp operation electronic product.
So via enforcement of the present utility model, when rotating shaft is when covering, its axial friction torsion is to be release, and by second elastic device of other side in the radial support cover body part.In addition,, can make revolving meber automatically open an angle, and the sheet of coupling component is protruding, and then to be moved to frame protruding, and cover body part is supported by coupling component and the formed friction torque of support again via the release that the elasticity of second elastic device is tightened.Be to be identical shortcoming, and when opening, this revolving part can provide a power-assisted, and very laborsaving with the torsion that, the utility model can change existing rotating shaft.
That the utility model disclosed is a kind of of preferred embodiment, the change of every part or modification and come from technological thought of the present utility model and be familiar with this skill the people was easy to know by inference, all do not take off patent right category of the present utility model.
