Description
Technical field
The utility model relates to a kind of focusing focus set, particularly relates to a kind of camera lens focusing structure of micro projector.
Background technology
Projector is as a kind of office equipment different occasions such as applied teaching, scientific research, meeting, report widely.The focusing mode of the projector of commonly using is that focusing ring is socketed in the camera lens exposed junction, moves forward and backward through rotating focusing ring driving camera lens, realizes focusing.This focusing mode of commonly using operates comparatively inconvenient, can't finely tune by the influence of camera lens focusing stroke itself again, also takies bigger structure space, is difficult to be applied on the pouch-type micro projector.
In view of this, the design people is not to attaining perfect many disappearances and the inconvenience that causes in the design of above-mentioned projector architecture, and deeply design, and the active research improvement has a fling at and development and Design goes out the utility model.
The utility model content
The purpose of the utility model is to provide the camera lens focusing structure of a kind of advantages of small volume, easy to operate micro projector.
For realizing above-mentioned purpose, the technical solution of the utility model is:
A kind of camera lens focusing structure of micro projector, it comprises casing, camera lens, focus adjusting mechanism, and casing is provided with a projection mouth and a focusing mouth, and lens movable is nested with in casing and corresponding projection mouth, and focus adjusting mechanism is installed on the camera lens; This focus adjusting mechanism comprises camera lens jacket casing wheel, soft gear bar, focusing gear and driving gear; Camera lens jacket casing wheel is placed on the camera lens, and this camera lens jacket casing wheel is provided with the wheel body that supplies soft gear bar to place, and an end of soft gear bar is fixed on one's body the wheel, and the other end is provided with the follower gear with the driving gear engagement; Focusing gear and the coaxial setting of driving gear, and be installed in the casing through rotating shaft is rotatable; The head portion of focusing gear stretches out the focusing mouth of casing.
The camera lens focusing structure of this micro projector comprises that also one is fixed in the gear fixed support in the casing; This gear fixed support is provided with gear space and gear bar track; Said focusing gear and driving gear are located in the gear space; And be installed on the gear fixed support through said rotating shaft is rotatable, said soft gear bar meshes through gear bar track and driving gear.
Said camera lens is provided with projection, and said camera lens jacket casing wheel is provided with the short slot that is nested with this projection.
The wheel of said camera lens jacket casing wheel is provided with the slotted eye that blocks soft gear bar one end on one's body, and said soft gear bar one end is fixed in this slotted eye.
After adopting such scheme; The camera lens focusing structure of the utility model micro projector is through the engagement with soft gear bar and driving gear; Make with the focusing gear driven camera lens jacket casing of the coaxial setting of driving gear and take turns and then drive the camera lens rotation, significantly reduce the volume of this micro projector; The head portion of focusing gear is stretched out the end face of casing, as long as rotation focusing gear just can drive the camera lens rotation, it is very convenient to operate during operation.The follower gear that adopts simultaneously, driving gear can realize that all different ratio of gear changes the focusing travel limits that changes camera lens itself, realizes camera lens focusing fine setting more accurately.

Embodiment
In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
As shown in Figure 1, the utility model is a kind of camera lens focusing structure of micro projector, and it comprises casing 1, camera lens 2, focus adjusting mechanism 3.
To shown in Figure 7, this focus adjusting mechanism 3 comprises camera lens jacket casing wheel 31, gear fixed support 32, soft gear bar 33, focusing gear 34 and driving gear 35 like Fig. 2.Camera lens 2 is provided with projection 21; This camera lens jacket casing wheel 31 is provided with the short slot 311 of corresponding projection 21; Through camera lens jacket casing wheel is placed on the camera lens 2; Rotate the camera lens jacket casing and take turns and can drive camera lens 2 at 31 o'clock and rotate, this camera lens jacket casing wheel 31 is provided with the wheel body 312 that supplies soft gear bar 33 to place, and on wheel body 312, is provided with the slotted eye 313 that blocks soft gear bar 33 1 ends; Gear fixed support 32 is fixedly arranged in the casing 1, comprises the gear space 321 and a gear bar track 322 of ccontaining focusing gear 34 and driving gear 35; One end activity of soft gear bar 33 is fixed in the slotted eye 311 of camera lens jacket casing wheel 31, and the other end is provided with the follower gear 331 with driving gear 35 engagements; Focusing gear 34 and driving gear 35 coaxial settings, and through rotating shaft 36 rotatable being installed on the gear fixed support 32, the head portion of focusing gear 34 stretches out the focusing mouth 12 of casing 1.
When the utility model uses; Rotate focusing gear 34; Focusing wheel 34 can drive the driving gear 35 of setting coaxial with it, and driving gear 35 drives move soft gear bar 33 with the follower gear 331 of its engagement in gear bar track 322, and soft gear bar 33 drives the camera lens jacket casing wheel 31 that is mated and rotates; Rotate thereby drive camera lens 2, realize focusing.
