Description
Technical field
The present invention is related to a kind of optical facilities, arranges boss to increase the optical facilities of straight cylinder and the bond strength of fixing cylinder in particular to a kind of root at straight cylinder.
Background technology
Refer to Fig. 1,2, its represent known optical lens axially with sectional view radially.Known optical lens 10 includes pedestal (not shown), fixing cylinder 12, cam canister 14, straight cylinder 16 and a plurality of groups of frames (not shown).Pedestal can be the base of the housing of photographing unit, and image sensing component is arranged on pedestal, and fixing cylinder 12 is fixed on pedestal, and straight cylinder 16 is arranged in fixing cylinder 12 and can axially move along the internal perisporium of fixing cylinder 12.When photographing unit is unlocked, cam canister 14, straight cylinder 16 and each group's frame can move from pedestal (in the housing of photographing unit) and stretch out outside the housing of photographing unit to wide angle shot position (WIDE), now straight cylinder 16 can be positioned at this position, cam canister 14 can rotate by the driving of motor, makes each group's frame axially move along straight cylinder 16 and produces the effect of zoom.
The internal perisporium of fixing cylinder 12 is formed three guide grooves 122,124 and 126, periphery wall at straight cylinder 16 forms three protruding pins 162,164 and 166, protruding pin 162,164 and 166 is embedded in guide groove 122,124 and 126 movably, therefore when straight cylinder 16 is moved to wide angle shot position by pedestal, guide groove 122,124 and 126 it is embedded in movably, it is possible to guide straight cylinder 16 and be smoothly axially moved to wide angle shot position along the internal perisporium of fixing cylinder 12 by protruding pin 162,164 and 166.Additionally, the chimeric of protruding pin 162,164 and 166 with guide groove 122,124 with 126 contributes to increasing structural strength, even if straight cylinder 16 meets with in wide angle shot position impacts (such as user drops photographing unit accidentally), also can possess certain structural strength, straight cylinder 16 escape and damage will not be made.
Summary of the invention
But in above-mentioned structure, owing to needing to arrange three guide grooves 122,124 and 126 on fixing cylinder 12, so can be separated by the region on the internal perisporium of fixing cylinder 12, make the configuration of the cam path on the internal perisporium of fixing cylinder 12 and design the restriction being subject to three guide grooves 122,124 and 126.Further, since three guide grooves 122,124 and 126 need to be offered on fixing cylinder 12, it is possible to the weakened of the barrel of fixing cylinder 12 can be caused.
In view of this, the technical problem to be solved in the present invention is in that, design for the cam path fixing cylinder in prior art is subject to the restriction of guide groove and the defect of the weakened of fixing cylinder, the structure that a kind of straight cylinder is combined with fixing cylinder is provided, configuration and the elasticity in design of fixing cylinder epirelief race can be increased, when wide angle shot position, the intensity of structure can be possessed again.
The present invention solves that its technical problem be employed technical scheme comprise that, it is provided that a kind of optical facilities, a preferred embodiment includes pedestal, fixing cylinder, straight cylinder, cam canister and at least a group frame.Fixing cylinder is fixed on this pedestal and at the axially formation only guide channel of internal perisporium, this fixing cylinder has top；Straight cylinder is movably arranged on this fixing cylinder, and has root；Cam canister is rotatably disposed within this fixing cylinder；Group's frame carrying battery of lens is also located in this cam canister, this group of frame drive by this cam canister and this straight cylinder spacing and axially move, wherein this straight cylinder forms only protruding pin on its periphery wall, this protruding pin is movably arranged in this guide channel, and form at least one boss at this root, when this straight cylinder movement to this root is contacted with this top of this fixing cylinder, this protruding pin and these boss are connected to this top of this fixing cylinder.
Above-mentioned preferred embodiment more includes guide rail, is axially arranged between this pedestal and this fixing cylinder, and this protruding pin is incorporated into this guide rail, and axially moves by the guiding of this guide rail.
In above-mentioned preferred embodiment, this root of this straight cylinder forms outer bead, these boss are formed in this outer bead, and this protruding pin protrudes from this outer bead, the top of this fixing cylinder has inward flange, and when this straight cylinder movement to this root is contacted with this top of this fixing cylinder, this protruding pin and these boss are connected to this inward flange.
Implement the optical facilities of the present invention, have the advantages that owing to only arranging a guide groove at the internal perisporium of fixing cylinder, the configuration of the cam path of the internal perisporium of so fixing cylinder and design can more multiformity, and fix cylinder owing to only arranging a guide groove, the intensity of structure there will not be the problem of reduction.

Detailed description of the invention
Refer to Fig. 3,4, it represents the structure of optical lens of the present invention.The optical lens 100 of the present invention includes pedestal 20, fixing cylinder 30, straight cylinder 40, cam canister 50 and group's frame 60.Image sensing component (non-icon) is arranged on pedestal 20, fixing cylinder 30 is fixed on pedestal 20, in the present embodiment, fixing cylinder 30 cylindrically, forms inward flange 32 at its top, and inward flange 32 radially extends inwardly, internal perisporium at fixing cylinder 30 forms unique guide groove 34, guide groove 34 is axially extending on internal perisporium, and straight cylinder 40 also cylindrically and be arranged in fixing cylinder 30, and can axially move along the internal perisporium of fixing cylinder 30.The root of straight cylinder 40 forms outer bead 42, outer bead 42 extends from the root side radially towards of straight cylinder, protruding pin 44 extends radially towards from outer bead 42, protruding pin 44 is embedded in guide groove 34 movably, bead 42 is provided with two boss 46 outside, referring to Fig. 5, boss 46 is axially extending in outer bead 42.Guide rail 5 is arranged between the top of pedestal 20 and fixing cylinder 30, and protruding pin 44 is movably in conjunction with guide rail 5.
When photographing unit is activated, straight cylinder 40 is embedded in the guiding of guide groove 34 and guide rail 5 by protruding pin 44 and moves the top to fixing cylinder 30 along the internal perisporium of fixing cylinder 30 from pedestal 20, and now straight cylinder 40 is positioned at wide angle shot position.When straight cylinder 40 moves to wide angle shot position, protruding pin 44 is connected to inward flange 32, and boss 46 is embedded in the recess 36 being located at inward flange 32, and straight cylinder 40 thereby can be made to be positioned wide angle shot position.After straight cylinder 40 is positioned wide angle shot position, cam canister 50 is driven by motor and rotates and drive group frame 60 to move and produce the effect of zoom.
In the optical lens 100 of the present invention, owing to only arranging a guide groove 34 at the internal perisporium of fixing cylinder 30, the configuration of the cam path of the internal perisporium of so fixing cylinder 30 and design can more multiformity, and fixing cylinder 30 is owing to only arranging a guide groove 34, and the intensity of structure there will not be the problem of reduction.It addition, be arranged at the boss 46 of the outer bead 42 of straight cylinder 40, when straight cylinder 40 is positioned wide angle shot position, it can be ensured that the intensity of structure, to avoid photographing unit to make straight cylinder 40 escape and damage when accidentally dropping.
Though the present invention is disclosed above with embodiment; but it is not used to limit the scope of the present invention, and those skilled in the art, without departing from the scope of the present invention; when doing a little change and retouching, therefore protection scope of the present invention is when being as the criterion depending on as defined in claim.
