See also Fig. 1; Preferred embodiments lens assembly of the present invention comprises that lens mount 10, elastic body 20, abutment ring 30, at least one (present embodiment is 3) are installed in slide post 40, regulating ring 50 and camera lens module 60 on the abutment ring 30, is provided with first chute 55 that at least one (present embodiment is 3) has the bottom in this regulating ring 50.This elastic body 20 is installed in the lens mount 10 with abutment ring 30, and this regulating ring 50 is sheathed on the lens mount 10, and this slide post 40 is fastened in first chute 55, and this camera lens module 60 and abutment ring 30 are through being threaded.

Said lens mount 10 comprises a base 11, be installed in the assembly parts 12 of base 11, three second chutes 13 and dog screws 14.This base 11 is provided with surface 111.These assembly parts 12 are annular, and it is installed on this surface 111.These assembly parts 12 are toroidal cavity, are provided with perisporium 121.Said three second chutes 13 are rectangular groove, and it is along the formation that extends axially of lens mount 10, and promptly it is along even spaced apart being located on this perisporium 121 of assembly parts 12 axial directions.Each second chute 13 is equipped with first end 131 and second end 132.Between 2 second chutes 13, also be provided with a fixed orifice 122 on this perisporium 121.This dog screw 14 can be installed in this fixed orifice 122.

Said elastic body 20 is the screw cylindrical shell fragment, and it can be installed in these assembly parts 12.Said abutment ring 30 is one can be installed in the torus in this assembly parts 12, and its inner ring surface is provided with internal thread 31.Second chute 13 of corresponding lens mount 10 is provided with pilot hole 32 on the outer ring surface relative with inner ring surface.Be provided with internal thread in this pilot hole 32.Said three slide posts 40 are provided with a sliding end 41 and relative with the sliding end 41 externally threaded link (figure is mark) that is provided with.In the time of when this slide post 40 is fixed in this pilot hole 32 through link in, the outer ring surface of these sliding end 41 these abutment rings 30 of protrusion.

Said regulating ring 50 is one can be sheathed on the torus on these assembly parts 12, and it comprises outside surface 51, inside surface 52 and locating slot 53.Convex with the fin that several vertically are provided with on this outside surface 51, can when hand rotation regulating ring 50, increase rotation friction.Said locating slot 53 is the strip groove, and it and laterally is opened on regulating ring 50 ring walls and runs through outside surface 51 and inside surface 52 between two first chutes 55.

Said three first chutes 55 are arranged with on this inside surface 52 with respect to these three slide posts 40.Said each chute 55 extends along the circumferencial direction of this regulating ring 50 in gradient, thereby corresponding each said first chute 55 forms an opening 551 on this inside surface 52, hold platform 552 and slide unit 553.This slide unit 553 is a runner wall of first chute 55, and its initiating terminal has a difference in height with respect to end.This opening 551 is opened in the initiating terminal of this slide unit 553 and runs through an end of this regulating ring 50.This holds platform 552 and is located on this slide unit 553 near opening 551 places.Holding platform 552 other ends on this slide unit 553 relatively is stop bit end 5531.In the present embodiment, this stop bit end 5531 axially is higher than and holds platform 552.

Said camera lens module 60 comprises a body 61, regulation cock 62 and is located at the external thread 63 of body 61 1 ends.Camera lens module 60 is threaded with the internal thread 131 of this abutment ring 30 through link 62.

See also Fig. 2 and Fig. 3; During assembling; Earlier elastic body 20 is loaded in the assembly parts 12; Then abutment ring 30 is loaded in the assembly parts 12 elastic body 20 compressions, slide post 40 is assemblied in the pilot hole 32 of this abutment ring 30 through second chute 13 on the assembly parts 12, the sliding end 41 of this slide post 40 passes second chute 13, and to expose this assembly parts 12 outer and be positioned at this second chute 13; Again this regulating ring 50 is placed on these assembly parts 12; The sliding end 41 of this slide post 41 is contained in the opening 551 of first chute 55 on this inside surface 52, rotates regulating ring 50, and this sliding end 41 is along holding the platform 552 sliding slide units 553 of going up; When this sliding end 41 is positioned at the centre position of second chute 13; Dog screw 14 passes locating slot 53 and with cooperating of fixed orifice 122 regulating ring 50 is located, and so promptly accomplishes assembling, these elastic body 20 its pre-compressed state.

Please consult Fig. 4 in the lump, when adjusting regulating ring 50 made these camera lens module 60 axial elongations, fine setting dog screw 14 was that first direction rotates regulating ring 50 along the direction of arrow, makes the sliding end 41 of slide post 40 slide into stop bit end 5531 along slide unit 553.Sliding end 41 slides towards second end 132 in second chute 13.When sliding end 41 was positioned at stop bit end 5531, sliding end 41 slid into second end, 132 places of second chute 13.At this moment, this dog screw 14 is fixed in an end of this locating slot 53.In this process; Because sliding end 41 is along the longitudinal sliding motion of second chute 13; This slide post 40 drives abutment rings 30 and moves away from lens mount 10, and the mobile auxiliary force that provides of 20 pairs of abutment rings 30 of elastic body simultaneously is because the cooperating of internal thread 31 and external thread 63; In this process, this camera lens module 60 vertically stretches out away from lens mount 10.

Please consult Fig. 3 and Fig. 5 in the lump; When regulating the relative lens mount indentation of this camera lens module 60, fine setting dog screw 14 is that second direction is rotated regulating ring 50 along the direction of arrow; The sliding end 41 that makes slide post 40 holds platform 552 along what slide unit 553 slided to first chute 55; Sliding end 41 slides into first end, 131 places of second chute 13 simultaneously, and this dog screw 14 is fixed in the other end of this locating slot 53, and this moment, the lock in place screw 14.Because sliding end 41 is along the longitudinal sliding motion of second chute 13, this slide post 410 drives abutment ring 30 and in the assembly parts 12 of lens mount 10, moves and compresses elastomeric 20 relative lens mount 10 indentations of this camera lens module.

The regulating ring 50 of said lens assembly is placed on the lens mount 10; It is provided with first chute 55, connects lens mount 10 and camera lens module 60 through abutment ring 30, on this abutment ring 30 slide post 40 is housed; This slide post 40 makes abutment ring 40 move relative to lens mount 10 along first chute, 55 slips of regulating ring 50; And then drive camera lens module 60 and move relative to lens mount 10, camera lens module 60 is rotated, the stability of assurance camera lens module 60.
