Embodiment
As shown in Figures 3 and 4, adjustable lens device preferred embodiment of the present invention comprises adjustment seat 20, that a holder 10, is set in these holder 10 outsides and is arranged in unit 30, first mirror cell and a pair of unit, second mirror cell 40 that should unit, first mirror cell 30 also be installed in this holder 10 in this holder 10.
This holder 10 is to make hollow tube-shape, and have one around an axis L and can define that fixed part 13, most ring that the perisporium 12, of an endoporus 11 radially extends outwardly by this perisporium 12 are located on this perisporium 12 and the locating piece 14 and that is provided with at interval with this fixed part 13 along this axis L by the outward extending limiting section 15 of these perisporium 12 1 sides.This perisporium 12 have a first end 121, a second end 122 along this axis L and these first end 121 opposite settings, most extend vertically and be located between this first and second end 121,122 guide groove 123 and a pair of should first end 121 and be located at the internal thread 124 of an inner peripheral surface, this the second end 122 is to be step shape, and to make 11 pairs of this endoporus should the second end 122 1 ports be to be dwindled gradually outwardly by interior.This limiting section 15 is to be extended and curved tabular by this first end 121, and has one first retaining edge 151 and and keep off edge 152 with second of these first retaining edge, 151 opposite settings.
This adjustment seat 20 also is to make hollow tube-shape, and can rotate with respect to this holder 10 appropriateness, and have a pair of end, location 21, that should fixed part 13 and be located between this end, location 21 and this operative end 22 and brake groove 23 should axis L extending in the shape of a spiral along the operative end 22 of this axis L and these end, location 21 opposite settings and majority.This end, location 21 has one and is arranged with in inner ring surface and can and mostly wears position 212 by what this annular groove 211 was through to outside and corresponding described locating piece 14 vertically for the sheathed annular groove 211 of described locating piece 14, and described locating piece 14 can be sheathed with in this annular groove 211 vertically via the described position 212 that wears, and should adjust seat 20 and rotate (staggering with described locating piece 14 as long as make the described position 212 that wears) after the suitable angle with respect to this holder 10, just can make this adjustments 20 with respect to these holder 10 generation axial location.
This unit, first mirror cell 30 is the optical applications as the pre-group mirror cell in the present embodiment, and have one first lens barrel 31, majority are installed in the eyeglass 32 of these first lens barrel, 31 inside, most spaced ring 33, between two eyeglasses 32 is arranged in this first lens barrel 31 and make described eyeglass 32 obtain axial limitings pressure ring 34, be positioned at this pressure ring 34 outside and be installed on this first lens barrel 31 protecting cover 35 and a pair of should limiting section 15 and be installed in set screw 36 on this first lens barrel 31.This first lens barrel 31 has an external thread 311 that can be arranged on this internal thread 124, utilize that this is outer, the screwing togather of internal thread 311,124, be these unit, first mirror cell 30 integral body can be produced along this axis L with respect to this holder 10 adjust, and utilize this set screw 36 to keep off cooperating of edge 151,152, can limit the rotational angle of this unit, first mirror cell 30 with this first and second.
This unit, second mirror cell 40 is to being installed in the second end 122 of this holder 10 unit, first mirror cell 30, be optical applications in the present embodiment, and have that one second lens barrel 41, majority are installed in the eyeglass 42 of these second lens barrel, 41 inside, most spaced ring 43, between two eyeglasses 42 is arranged in this second lens barrel 41 and make described eyeglass 42 obtain the pressure ring 44 of axial limitings and mostly be convexly equipped with on this second lens barrel 41 and be located in guide member 45 in described guide groove 123, the brake groove 23 as back group mirror cell.This second lens barrel 41 is to cooperate the second end 122 that is step shape also to be class's tubular.
Again as shown in Figures 3 and 4, when this lens assembly assembly is finished, unit, the two or two mirror cell 40 is to be installed in this holder 10 inside, and this adjustment seat 20 is set in this holder 10 outsides, make described brake groove 23 be symmetrical in described guide groove 123, and supply described guide member 45 to pass described guide groove 123 and brake groove 23 simultaneously, and utilize described locating piece 14 to be embedded in this annular groove 211, can make this adjustment seat 20 produce axial location with respect to this holder 10, and utilize cooperating of described brake groove 23 and described guide member 45, then can limit the angles that this adjustment seat 20 rotates with respect to this holder 10.
Again as shown in Figure 5, when this adjustments of operation 20 rotates with respect to this holder 10, utilize that described brake groove 23 extends in the shape of a spiral, described guide groove 123 extends vertically, and the effect that utilizes the described guide member 45 of described brake groove 23 stoppers, make these unit, second mirror cell 40 integral body produce displacement in opposite directions with respect to this unit, first mirror cell 30, can reach the zoom purpose along this axis L.And, can make this unit, second mirror cell 40 revert back to the state of Fig. 4 again if should adjust 20 reverse rotations again the time.
And under state shown in Fig. 4 and Fig. 5, operating this unit, first mirror cell 30 rotates with respect to this holder 10, and utilize first and second retaining edge 151,152 of these limiting section 15 both sides and cooperating of set screw 36, the operation in the predetermined anglec of rotation of this unit, first mirror cell 30 is adjusted.
Therefore, lens assembly of the present invention, utilize described locating piece 14 to be embedded in this annular groove 211, make this adjustment seat 20 produce axial location with respect to this holder 10, utilize the setting of described brake groove 23 then can limit the angle that this adjustment seat 20 rotates with respect to this holder 10, and described locating slot 14, annular groove 211 simple in structure, make that assembly is easy, processing cost is low, and the also more existing lens assembly of the member of lens assembly integral body comparatively simplifies, and can reduce manufacturing cost.Moreover, the present invention utilizes cooperating of described locating piece 14 and annular groove 211, produced axial location so that should adjust seat 20 with respect to this holder 10, and compared to known described stop ditch 102 must be set on this holder 1, manufacturing then of the present invention, processing cost can be lower.
What deserves to be mentioned is, the foregoing description is to make the optical applications of this unit, second mirror cell 40 as back group mirror cell, and produce displacements to reach the zoom purpose with respect to this holder 10, but use identical structure, also can make this unit, first mirror cell 30 produce displacement, also can reach zoom purpose (figure does not show) with respect to this holder 10.And the unit, first mirror cell 30 of the foregoing description be utilize that this is outer, the screwing togather of internal thread 311,124, can produce along this axis L with respect to this holder 10 and adjust, but also can utilize on this adjustment seat 20 and set up brake groove, guide member be set (figure does not show) on this unit, first mirror cell 30, and utilize this adjustment seat 20 of operation to produce in opposite directions or opposite displacement with respect to holder 10, also can reach the zoom purpose with this first and second unit, mirror cell 40 of while stopper.
The above, it only is preferred embodiment of the present invention, when not limiting scope of the invention process with this, promptly the simple equivalent of being done according to the present patent application claim and invention description content generally changes and modifies, and all still belongs in the scope that patent of the present invention contains.
