Said lens base is connected to a lamp panel base via a lamp panel fixing column. A angle gear and a distance gear are also provided sequentially between the lens base and the lamp panel base, wherein the distance gear is engaged with a distance pinion, the angle gear with a angle pinion, and the angle pinion and the distance pinion are mounted between the lens base and the lamp panel base with a distance gear shaft and an angle gear shaft.

Description

The quickcam image focusing device
Technical field
The utility model relates to camera, mainly is meant a kind of quickcam image focusing device.
Background technology
The camera lens of known camera mainly is to rotate by bungee pulling camera lens to realize focusing, so there is following shortcoming: and 1, inaccurate, because its institute's elastic force that relies on tension has bounce situations, so be difficult to be transferred to the appropriate location; 2, instability, temperature influence causes the elasticity instability easily; 3, camera lens is fragile, influenced by rubber lacing wire power.
Summary of the invention
The purpose of this utility model provides a kind of quickcam image focusing device, and therefore the focusing by set of gears mechanism realizes camera lens has solved the defective that prior art exists.
The realization the technical solution of the utility model is: this quickcam image focusing device comprises base, little centre circle, big centre circle, focalizer, bulb, camera lens, its primary structure is that camera lens is arranged on the focalizer, focalizer is arranged in the bulb, wherein focalizer comprises a camera lens base, this camera lens base links together by a lamp plate fixed leg and a luminous board seat, between camera lens base and luminous board seat, also be sequentially set with angle gear and apart from gear, its middle distance gearing mesh one is apart from pinion wheel, angle gear meshes an angle pinion wheel, angle pinion wheel and be installed between camera lens base and the luminous board seat by distance gear shaft and angle gear axle respectively apart from pinion wheel.
This technical scheme also comprises:
The front end of described camera lens is fixed in the hole apart from gear, and the rear end of camera lens is arranged in the hole of camera lens base, and the ladder platform of rear end is fixed in the hole of angle gear, and the camera lens base is fixed in the bulb by the focalizer fixed leg.
Described bulb is provided with the focusing hole, is the upper end apart from gear shaft and angle gear axle in this hole, is provided with waterproof apron between the upper end of its middle distance gear shaft and angle gear axle and the focusing hole.
Described lamp plate fixed leg and focalizer fixed leg are respectively 4.
The beneficial effect that the utlity model has:
1, degree of accuracy height rotates by gear;
2, good stability is difficult for temperature influence;
3, can not cause damage to camera lens, not stressed when normal condition or duty to camera lens, because of the center of circle of installing and camera lens respectively has independence to rotate;
4, invariant position, (fixedly cushion rubber of shockproof waterproof is arranged) can not draw return automatically because of camera lens.
Description of drawings
Fig. 1 is a general structure synoptic diagram of the present utility model, and expression camera lens and base are horizontal level, wherein 1 camera lens, 2 bulbs, 3 focalizers, 4 big centre circles, 5 little centre circles, 6 bases.
Fig. 2 is the semisectional view of Fig. 1, and expression camera lens and base are the upright position, wherein 21 bulb upper casings, 22 bulb lower casings.
Fig. 3 is a bulb cut-open view among Fig. 1, the expression focalizer is installed in the position of bulb, wherein 31 camera lens bases, 32 angle gears, 33 angle pinion wheels, 34 angle gear axles, 35 apart from gear shaft, 36 apart from pinion wheel, 37 apart from gear, 38 luminous board seats, 211 focusing holes, 212 waterproof aprons.
Fig. 4 is a focalizer general assembly synoptic diagram.
Fig. 5 is focalizer assembling decomposing schematic representation, wherein 7 lamp plate fixed legs, 8 screws, 9 lamp plate fixed legs, 341 openings.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, this focalizer 3 belongs to the focus control of cam lens 1, it is mainly by camera lens base 31, angle gear 32, apart from gear 37, luminous board seat 38, apart from gear shaft 35, angle gear axle 34, angle pinion wheel 33, form apart from pinion wheel 36, be angle gear above the camera lens base 31 wherein, be apart from gear 37 above the angle gear 32, apart from being luminous board seat 38 above the gear 37, lamp plate fixed leg 9 is fitted together above-mentioned set of devices, wherein angle pinion wheel 33 drives angle gear 32 rotations, drive apart from gear 37 rotations apart from pinion wheel 36, reach focusing and transfer real purpose.
Focalizer principle of work (rotary action of gear):
1, fastening apart from gear 37 and camera lens roll adjustment from (focusing) position, during adjustable range gear shaft 35, drive camera lens focusing position by distance gear 37 and rotate, and reached the focusing effect, the clear optimum condition of adjusting to.
2, angle gear 32 is fastening with camera lens hue angle position, when adjusting angle gear shaft 34, drives camera lens hue angle position by angle gear 32 and rotates, and changes and reached the camera lens camera angle, focuses on the CCD apart from the shadow thing a certain, reaches best sharpness.
The focalizer using method: using common straight screwdriver, is that the scalable camera lens is looked distance at place, casing focusing hole rotation axis 34 and axle 35.
The utility model can be used for various cameras, and protects the use of this focalizer at other camera.
