First spindle nose 11 and second spindle nose 21 are respectively convexly equipped with two end faces to setting, and the first spindle nose 11 and the second spindle nose 21 are in circumference
Upper have interval, for first rotating shaft 10 and the second rotating shaft 20 relative around circumferentially rotate when, coordinate and limit 10 He of first rotating shaft
Relatively turnable angular dimension between second rotating shaft 20.
By arranging sleeve 30, first rotating shaft 10 and the second rotating shaft 20 are carried out spacing, it is ensured that the of first rotating shaft 10
Do not deviate from second body, 200 rotation process of one body 100 and the second rotating shaft 20,
In conjunction with Fig. 3, it is preferable that the first spindle nose 11 and the second spindle nose 21 respectively with the first noumenon 100 of first rotating shaft 10 and
The outer surface radian of the second body 200 of the second rotating shaft 20 is identical.By such design, in first rotating shaft 10 and the second rotating shaft
During 20 relatively rotate, the first spindle nose 11 and the second spindle nose 21 are contacted all the time with sleeve interior surface, are limited by interference engagement
Fixed first spindle nose 11 and the relative rotation angle of the second spindle nose 21, make the two rotate in sleeve 30 more steady.
Further, it is preferable to the first spindle nose 11 and the second spindle nose 21 are sector in circumferential section, so as in first rotating shaft
10 and second rotating shaft 20 relatively rotate to the two contact after, the first spindle nose 11 and the second spindle nose 21 can be fitted completely, with most
Big contact area.
Wherein, the surface of the first spindle nose 11 and the contact of the second spindle nose 21 can be preferred for plane or cambered surface, the present embodiment
The contact surface of the two is plane, makes the two contact area bigger, and stress is evenly, it is to avoid stress concentration causes the damage of spindle nose
Bad.
In order to ensure that the first spindle nose 11 and the second spindle nose 21 can be relatively rotated, the first spindle nose 11 and the second spindle nose 21 are in week
There is interval upwards, in the present embodiment, in an initial condition, between the first spindle nose 11 and the second spindle nose 21, be spaced certain angle
θ, two rotating shafts can carry out relative rotation angle, θ forward or backwards.
By arranging interval angles θ, two rotating shafts suitably can be rotated, it is ensured that the bendable folding endurance of product, while
The bending angle of product can be limited in safety range again, protect product and internal bus-bar construction.
Sleeve 30 is tube structure, is respectively provided with the first spindle nose 11 and the second spindle nose in first rotating shaft 10 and the second rotating shaft 20
In 21 one end insertion sleeve 30.Here, outside the second body 200 of the first noumenon 100 of first rotating shaft 10 and the second rotating shaft 20
Footpath is identical.It is preferred that sleeve 30 and 20 interference fit of first rotating shaft 10 and the second rotating shaft.
Further, more smooth in insertion rotating shaft in order to ensure sleeve 30, sleeve 30 is respectively arranged at two ends with the first breach
30a and the second breach 30b, in the present embodiment, the first breach 30a and the second breach 30b respectively have a pair, it is to be understood that the
The quantity of one breach 30a and the second breach 30b freely can also be arranged as needed.
The axial wall surface of first rotating shaft 10 and the second rotating shaft 20 further respectively has the first back-up ring 12 and the second back-up ring 22, is used for
Respectively first rotating shaft 10 and the second rotating shaft 20 are axially carried out after 20 insertion sleeve 30 of first rotating shaft 10 and the second rotating shaft spacing,
Also the contact length of first spindle nose 11 and second spindle nose 21 is controlled.
The other end relative with the first spindle nose 11 of first rotating shaft 10 also includes the first extension 13, the second rotating shaft 20 and second
The relative other end of spindle nose 21 also includes being respectively equipped with first on the second extension 23, the first extension 13 and the second extension 23
Through hole 14 and the second through hole 24.First extension 13 and the second extension 23 or first through hole 14 and the second through hole 24 can be with products
The two ends of winding displacement, electric connection line on product connect respectively, to prevent circuit connection from interrupting because of product distortion, turnover etc.；Or
Person's the first extension 13 and the second extension 23 or first through hole 14 and the second through hole 24 respectively with two relative rotations zero
Part connection reaches the effect of rotational angle restriction to complete rotational action.
Further, on 30 inwall of sleeve, the position of corresponding first spindle nose 11 and the second spindle nose 21 is additionally provided with least one
Individual raised (not shown), for its angle limit effect of the first spindle nose and the second spindle nose, by limiting the first spindle nose 11 and the
The size of the rotational angle of two spindle noses 21 can prevent the two from excessively rotating in one direction and damaging coupled part.
Embodiment 2
As shown in figure 4, for the compound rotating shaft cross section structure schematic diagram of the present embodiment, as different from Example 1, first axle
The 11, second spindle nose 21 is multiple, and the center with the center of first rotating shaft 10 and the second rotating shaft 20 is being justified as the center of circle respectively
Evenly distributed on week, and 21 interval setting of the first spindle nose 11 and the second spindle nose.21 interval angles θ of first spindle nose 11 and the second spindle nose
1 can need voluntarily to arrange size according to actual rotation.By more spindle noses are arranged on axle, further increase the rotation of two axles
Contact area when turning, has effectively disperseed the stress produced in rotation process, has protected shaft head structure.
