Embodiment
See also Fig. 1 and Fig. 2, the utility model is a kind of pivot that is used to rotate phtographic lens, is used in particular for being installed on the electronic product with phtographic lens, so that the rotation of phtographic lens to be provided.Its main member comprises:
One hollow axle 10, its side have the connecting portion 11 that is connected with the phtographic lens (figure does not show) of electronic product; In addition and offer a pair of pickup groove 12 at the inwall of rotating shaft 10.
One pipe spring spare 20, be located at rotating shaft 10 inside, have a pipe spring portion 21, offered wavy breach 25 together on it, and in pipe spring portion 21 relatively the position of breach 25 be provided with the prominent point 24 in a location, it is one plane that the embodiment in Fig. 1 should locate a surface of contact of dashing forward.One section arc-like sheet 22 is extended in side in pipe spring portion 21, and outwards be folded into a pair of stator 23 respectively at arc-like sheet 22 two ends, this can insert 12 pairs of pickup grooves on hollow axle 10 inwalls just to stator 23, make whole pipe spring spare 20 be fixed in the hollow axle 10, and rotate with hollow axle 10.
One stationary shaft 30 has an axial region 31 and a junction 32; Offered perforation 36 on the connecting portion 32 and can lock spiral shell and be fixed on the electronic product.Axial region 31 is sleeved in the pipe spring portion 21 of pipe spring spare 20, and is being provided with a pair of interference part 33 with respect to prominent point 24 positions, location in the pipe spring portion 21, and interference part 33 is the plane with the surface of contact of the prominent point 24 in location in the embodiment in figure 1; And two interference parts 33 are the opposition that are 180 degree relatively.When pipe spring spare 20 together rotates with hollow axle 10, when wherein an interference part 33 contacts with the prominent point in location in the pipe spring portion 21, hollow axle 10 meeting relative fixed axles 30 generation locating effects then.In addition, the other end of the axial region 31 relative connecting portions 32 of stationary shaft 30 is provided with the minor axis 34 of a diameter less than axial region 31.The axial region 31 of stationary shaft 30 offers oil duct 35 with the pipe spring portion 21 fit positions of pipe spring spare 20.
One bearing seat 40 is socketed on the other end of the axial region 31 relative connecting portions 32 of stationary shaft 30, makes the axial region 31 of stationary shaft 30 be held in the hollow axle 10.Bearing seat 40 is connecting portion 11 1 side end faces that sealing hollow axle 10 is connected with phtographic lens.
Please cooperate Fig. 3 and Fig. 4, when whole pivot is assembled finish after, hollow axle 10 can drive phtographic lens relative fixed axle 30 and back and forth rotate, shown in arrow G among Fig. 3, and by the pipe spring spare 20 pipe spring portion 21 clamping torsion is provided, but make hollow axle 10 relative fixed axles 30 rotate to unspecified angle.
The person of advancing when the hollow axle 10 relative fixed axles 30 of the utility model pivot rotate, when the interference part 33 on stationary shaft 30 contacts with the prominent point 24 in the location on managing spring spare 20, makes hollow axle 10 relative fixed axles 30 produce locating effects.Because two interference parts 33 are to be 180 degree opposition, making the locating effect of hollow axle 10 and stationary shaft 30 occur in both is 0 degree and 180 degree positions, and just 0 degree and the 180 degree positions of phtographic lens on electronic product have locating effect.
The utility model makes the combinative stability degree of whole pivot greatly improve because pipe spring spare 20 formed stators 23 stretch in the inwall pickup groove 12 of hollow axle 10, can prolong the serviceable life of whole pivot.
Figure 5 shows that the another kind of embodiment of the utility model, its embodiment to Fig. 1 is similar, have that hollow turns 10, pipe spring spare 20 and stationary shaft 30, but on the surface of contact of the interference part 33a on prominent some 24a of the location in pipe spring spare 20 and the stationary shaft 30, then be cambered surface design, to improve the locating effect between hollow axle 10 and the stationary shaft 30.
Certainly, the interference part on the stationary shaft of the present utility model is not defined as two, can be one or morely yet, needs orientation angle and increases and decreases with the phtographic lens that cooperates hollow axle to connect.This is a simple change of the present utility model, still belongs among the scope of patent protection.
To sum up institute is old, and pivot symbol novelty of patent provided by the utility model and progressive key element are filed an application then in accordance with the law.
