Abstract
The utility model provides a novel frictional pivot hinge which comprises a pivot and a pivot sleeve, wherein the pivot is a metal shaft, and the pivot is provided with transverse through holes, so that the pivot has elasticity at the transverse through holes; and due to the assembling relation between the pivot sleeve and the pivot, the metal shaft is squeezed towards the intra-hole direction on the hole wall of the transverse through hole. According to the utility model, a through narrow groove is cut in the pivot, when the pivot is squeezed by the outside, and due to the existence of the narrow groove, the pivot has trace extrusion deformation, so that the pivot has certain elasticity; therefore, when the pivot is inserted in a pivot hole of the pivot sleeve, and the pivot can have elastic deformation, so that a friction phenomenon occurs between the outer wall of the pivot and the inner wall of the pivot hole of the pivot sleeve, thereby generating an enough constant torque capable of resisting a driving torque of 300 N.mm, therefore, the pivot hinge has a 'stop at any time' function; and in addition, the number, shape and spacing of the transverse through holes disclosed by the utility model can be increased, decreased or changed according to actual situations.
Description
Technical field
The utility model relates to hinge, relates in particular to apply to the portable type electronic product terminal, such as mobile phone, notebook computer, gaming machine etc.
Background technique
Along with the slimming day by day of the portable type electronic product terminals such as mobile phone, notebook computer, gaming machine, harsher to the requirement of using linkage structure wherein.Such as shaft hinge, not only require it more tiny, and every mechanical index still to meet normal usage requirement.For the friction shaft hinge, in case that axle is reduced to is very tiny, the frictional force between itself and axle sleeve is difficult to up to standard.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Novel friction shaft hinge, and it still can make rotating shaft and axle sleeve have enough frictional force in the situation that rotating shaft is reduced to very carefully.For this reason, the utility model is by the following technical solutions:
A kind of Novel friction shaft hinge comprises rotating shaft and axle sleeve, it is characterized in that:
Described rotating shaft is metal shaft, has cross through hole in described rotating shaft, makes described rotating shaft have elasticity the cross through hole place is set; The assembly relation of described axle sleeve and rotating shaft makes described metal shaft be subjected to the extruding of direction in the hole at the hole wall at cross through hole place.
On the basis of adopting technique scheme, the utility model also can adopt following further technological scheme:
Described rotating shaft has projection on the surface at cross through hole place.
Described cross through hole is along the axially extended fine seam type through hole of rotating shaft.
Described cross through hole is radial direction through hole.
Described axle sleeve is metal injection moulding spare (MIM).
Described axle sleeve has the connection part that is connected for main body that it is fixed in, the first end of axle sleeve has the restraining groove of restriction rotating shaft rotation angle, rotating shaft is stepped ramp type, coordinate with the first end of axle sleeve with step surface to limit the length that axle sleeve is inserted in rotating shaft, described rotating shaft is provided with the key that coordinates with described restraining groove.
The diameter of described rotating shaft is between 1.4mm to 2.4mm, and the thinnest part wall thickness of the rotating shaft hole wall of described axle sleeve is between 0.5mm to 1.2mm.
Owing to adopting the technical solution of the utility model, the utility model cuts out the narrow groove of perforation in rotating shaft, and when rotating shaft was subjected to extraneous extruding, because the existence of narrow groove is arranged, the rotating shaft meeting extrusion-deformation of trace occured and has certain elasticity; Therefore, when rotating shaft is inserted in the axis hole of axle sleeve, resiliently deformable can occur in rotating shaft, and the shaft hole inner wall of rotating shaft outer wall and axle sleeve is rubbed, thereby produce enough constant-torques, having and can resist up to 300 Ns. the function of the moment of rotation of millimeter (N.mm) " stopping at any time ", in addition, the quantity of the utility model cross through hole, shape and spacing all can increase or reduce or change according to actual conditions.

Fig. 2 is embodiment's provided by the utility model explosive view.
Fig. 3 is the A-A sectional view of Fig. 1.
Fig. 4 is the motion principle schematic diagram of rotating shaft and axle sleeve frictional fit.
Embodiment
With reference to accompanying drawing.Novel friction shaft hinge provided by the utility model comprises rotating shaft 1 and axle sleeve 2.
Described rotating shaft 1 is metal shaft, has cross through hole 11 in described rotating shaft 1, makes described rotating shaft have elasticity cross through hole 11 places are set; The assembly relation of described axle sleeve 2 and rotating shaft makes described metal shaft be subjected to the extruding of direction B in the hole at the hole wall at cross through hole place.The quantity of cross through hole can increase or reduce or change according to actual conditions, such as 1 hole, 2 holes or 3 holes are set.
In order to improve effect and to be convenient to assembling, described rotating shaft 1 has projection 12 on the surface at cross through hole 11 places.
The shape of cross through hole 11 and spacing also all can according to circumstances change, and in the present embodiment, described cross through hole 11 adopts along the axially extended fine seam type through hole of rotating shaft.Described cross through hole can also be radial direction through hole.
Owing to adopting turning shaft structure of the present utility model, in frictional fit, requirement to axle sleeve 2 can be lowered, make axle sleeve 2 can adopt metal injection moulding spare (MIM), like this, both be convenient to produce the complex model that meets designing requirement, controlled cost, guarantee again and rotating shaft between frictional fit in have satisfactory frictional force.
Described axle sleeve 2 tools have the connection part that is connected for main body that it is fixed in, such as a shank 20 with attachment hole, the first end 21 of axle sleeve has the restraining groove of restriction rotating shaft rotation angle, rotating shaft is stepped ramp type, coordinate with the first end of axle sleeve with step surface 12 to limit the length that axle sleeve is inserted in rotating shaft, described rotating shaft is provided with the key 13 that coordinates with described restraining groove.
In the utility model, the diameter of described rotating shaft is between 1.4mm to 2.4mm, thinnest part 22 wall thickness of the rotating shaft hole wall of described axle sleeve are between 0.5mm to 1.2mm, nonetheless, the utility model still can have enough intensity and enough frictional force is provided, and can resist up to 300 Ns. centimetre moment of rotation.
