In view of this, the design people does not attain perfect caused many disappearances and inconvenience in the design of above-mentioned projector architecture, and deeply conceives, and active research improvement has a fling at and development and Design goes out the utility model.
Utility model content
The purpose of this utility model is the focusing structure providing a kind of micro projector, and its structure is simple, compact and easy to operate.
In order to reach above-mentioned purpose, solution of the present utility model is:
Focusing structure in a kind of micro projector, ray machine is arranged in projector casing, the side of ray machine is provided with a focusing structure, this focusing structure includes a focusing wheel, focusing wheel is positioned on a fixation clip, focusing wheel includes focusing gear and to be positioned at below focusing gear and the coaxial driving gear arranged, the side of ray machine is provided with a ray machine driving lever, this ray machine driving lever holding is on the side of a sliding shoe, this sliding shoe side is vertically extended with a connecting piece, a bar-shaped trough is provided with in brace, the rotating shaft of one eccentric gear is stretched and is put in bar-shaped trough, driving gear in focusing wheel engages with between this eccentric gear.
Further, be connected a transition wheel between driving gear with eccentric gear, driving gear engages with transition wheel, and transition wheel engages with eccentric gear simultaneously.
Further, be provided with a locating slot in fixation clip, focusing gear is arranged in locating slot, and driving gear then stretches out in below fixation clip.
When the utility model uses, rotate focusing wheel, driving gear in focusing wheel rotates and drives the transition wheel engaged with it afterwards, transition wheel drives eccentric gear to rotate further, the eccentric rotary of eccentric gear, promote the to-and-fro movement that sliding shoe carries out front and back, the spacing of ray machine and camera lens is regulated, thus realize focusing.The utility model structure is simple, compact and easy to operate.

Embodiment
In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.
Shown in composition graphs 1, Fig. 2, the focusing structure of a kind of micro projector of the present utility model, in micro projector, ray machine 2 is arranged in projector casing 1, and casing 1 is provided with focusing mouth 11.A focusing structure 3 is provided with at the side of ray machine, this focusing structure 3 includes a focusing wheel 31, focusing wheel 31 is positioned on a fixation clip 32, focusing wheel 31 include focusing gear 311 and and the driving gear 312 that is positioned at below focusing gear, focusing gear 311 is coaxially arranged with driving gear 312.A locating slot 321 is provided with in fixation clip 32, focusing gear 311 is arranged in locating slot 321, driving gear 312 then stretches out in below fixation clip 32, focusing gear 311 in focusing wheel 31 just stretches out locating slot 312 and is exposed at outward in focusing mouth 12, thus can directly rotate focusing wheel 31 on casing.
Shown in composition graphs 1 to Fig. 6, simultaneously, the side of ray machine 2 stretches out a ray machine driving lever 21, the outer end holding of this ray machine driving lever 21 is on a sliding shoe 33, ray machine driving lever 21 holding is arranged in a draw-in groove 331 on sliding shoe 33 side, thus sliding shoe 33 moves and will drive ray machine driving lever 21, and then whole ray machine is driven to move reciprocatingly.Sliding shoe 33 side is vertically extended with the brace 332 of a strip of sheet, is provided with bar-shaped trough 333, eccentric gear 34 in brace 332 and is positioned at below brace 332, and the rotating shaft 341 of eccentric gear 34 is stretched and put in bar-shaped trough 333.Sliding shoe 33 is positioned at fixation clip 32 side, and brace 332 is positioned at below fixation clip 32, and the driving gear 312 in focusing wheel 31 engages with being formed between this eccentric gear 34.When gear 311 of focusing rotates, driving gear 312 rotates the rotation by driving eccentric gear 34, eccentric gear 34 carries out eccentric rotary, when eccentric gear 34 rotates, its rotating shaft 341 being arranged in bar-shaped trough 333 can drive sliding shoe 33 and sliding shoe is being moved relative to driving gear 312 generation, thus the movement of sliding shoe 33 can drive ray machine driving lever 21 to move forward and backward, and then whole ray machine can be driven to move reciprocatingly.By rotating focusing wheel 31, and then eccentric gear 34 drives sliding shoe 33, the distance namely between adjustable ray machine and camera lens, reaches the object of focusing.
In the present embodiment, for making engaged transmission between focusing wheel 31 and eccentric gear 34 more smooth and easy, more flexible on anatomical connectivity, also can be connected a transition wheel 35 between driving gear 312 with eccentric gear 34, driving gear 312 engages with transition wheel 35, and transition wheel 35 engages with eccentric gear 34 simultaneously, and driving gear 312 rotates and drives transition wheel 35, transition wheel 35 rotates the rotation also driving eccentric gear 34, has driven the movement of sliding shoe 33 equally.
When the utility model uses, rotate focusing wheel 31, driving gear 312 in focusing wheel 31 rotates the transition wheel 35 that rear drive is engaged with it, transition wheel 35 drives eccentric gear 34 to rotate further, the eccentric rotary of eccentric gear 34, promote the to-and-fro movement that sliding shoe 33 carries out front and back, the spacing of ray machine and camera lens is regulated, thus realize focusing.The utility model structure is simple, compact and easy to operate.
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
