Description
Technical field
The utility model relates to light fixture focus technique, especially a kind of wide-angle manual focusing structure.
Background technology
In existing market, the camera lens focusing mode of the overwhelming majority is all coordinate driving chip to carry out control with stepper motor, so not only very high to the required precision of mould, and the design in mechanism is also quite complicated, the original paper cost related to is quite high, the collocation of stepper motor and gear drives to be afraid of to run into collision most, once there be the effect of whole group of the design load focusing of a little skew will entanglement, even there is the jammed phenomenon of camera lens.Also there is the mechanism of manual focusing at present, but focusing angle is little, structure relative complex.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of wide-angle manual focusing structure, and structure is simple, and volume is little, and focusing angle is large, and manual zoom is without card.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of wide-angle manual focusing structure, comprises focusing lens parts, the lens be arranged on focusing lens parts, gripper shoe and the light source be located in gripper shoe; Bull tooth bar and slide bar is provided with between described focusing lens parts and gripper shoe; On described focusing lens parts, corresponding described slide bar place is provided with pilot hole, and one end of described slide bar is fixing on the supporting plate, and the other end is through described pilot hole; Described bull tooth bar comprises thread segment and polished rod section, and on described thread segment, cover has slide block, and described slide block and thread segment are for being threaded, and described slide block is fixedly connected with focusing lens parts; The corresponding described polished rod section place of described gripper shoe is provided with perforation, and one end of described polished rod section is connected with thread segment, and the other end passes described perforation and is connected with knob cap.Utility model works principle: focusing lens parts due to be subject to slide bar and bull tooth bar support under, can be stable form certain focussing distance with light source; When needs are focused to lens, manual rotation knob cap, drives bull tooth bar to rotate, thus converts the relative movement of slide block on thread segment to; Because slide block is connected with focusing lens parts, slide block can drive lens translation together, thus realizes the focusing of light fixture.This focusing structure is simple, and volume is little, and focusing angle is large, and manual zoom is without card.
As improvement, described lens are screw thread mirror.
As improvement, in described polished rod section, cover has flange seat, and described flange seat is provided with pivoted hole, and described polished rod section is placed in pivoted hole; Flange seat lower end is fixing on the supporting plate.
As improvement, described polished rod section is provided with the first caulking groove, the first jump ring be fastened in the first caulking groove, the second caulking groove and the second jump ring of being fastened in the second caulking groove; First jump ring is positioned at the tip position of flange seat, and the second jump ring is positioned at the bottom position of gripper shoe.First jump ring coordinates with the second jump ring and is clamped by flange seat, prevents bull tooth bar play.
The beneficial effect that the utility model is compared with prior art brought is:
When needs are focused to lens, manual rotation knob cap, drives bull tooth bar to rotate, thus converts the relative movement of slide block on thread segment to; Because slide block is connected with focusing lens parts, slide block can drive lens translation together, thus realizes the focusing of light fixture, and this focusing structure is simple, and volume is little, and focusing angle is large, and manual zoom pauses without card.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of wide-angle manual focusing structure, comprises focusing lens parts 4, the lens 3 be arranged on focusing lens parts 4, gripper shoe 1 and the light source 2 be located in gripper shoe 1.Described lens 2 are screw thread mirror.Be provided with installing hole in the middle of focusing lens parts 4, described installing hole place is located at by lens, and light source 2 is positioned at immediately below lens 3; The edge of focusing lens parts 4 is provided with protuberance 41, and described protuberance 41 position is provided with pilot hole and through hole, and this kind of special-shaped focusing lens parts 4 can realize enough positions and install, and also can alleviate the weight of focusing lens parts 4.Be provided with bull tooth bar 6 and slide bar 5 between described focusing lens parts 4 and gripper shoe 1, bull tooth bar 6 and slide bar 5 are distributed in the both sides of focusing lens parts 4, form symmetrical supporting mechanism.One end of described slide bar 5 is fixed in gripper shoe 1, and the other end is through described pilot hole, and pilot hole and slide bar 5 become guiding mechanism, contributes to focusing lens parts 4 stablizing when walking.Described bull tooth bar 6 comprises thread segment 61 and polished rod section 62, and on described thread segment 61, cover has slide block 7, and described slide block 7 and thread segment 61 are for being threaded, and described slide block 7 is fixedly connected with focusing lens parts 4; Corresponding described polished rod section 62 place of described gripper shoe 1 is provided with perforation, and one end of described polished rod section 62 is connected with thread segment 61, and the other end passes described perforation and is connected with knob cap 8.In described polished rod section 62, cover has flange seat 9, and described flange seat 9 is provided with pivoted hole, and described polished rod section 62 is placed in pivoted hole, and polished rod section 62 can rotate freely, and flange seat 9 lower end is fixed in gripper shoe 1; The second jump ring 11 that described polished rod section 62 is provided with the first caulking groove, is fastened on the first jump ring 10, second caulking groove in the first caulking groove and is fastened in the second caulking groove; First jump ring 10 is positioned at the tip position of flange seat 9, and the second jump ring 11 is positioned at the bottom position of gripper shoe 1, and the first jump ring 10 coordinates with the second jump ring 11 and clamped by flange seat 9, and jump ring prevents bull tooth bar 6 play as spacing.
Utility model works principle: focusing lens parts 4 due to be subject to slide bar 5 and bull tooth bar 6 support under, can be stable form certain focussing distance with light source; When needs are focused to lens, manual rotation knob cap 8, drives bull tooth bar 6 to rotate, thus converts the relative movement of slide block 7 on thread segment 61 to; Because slide block 7 is connected with focusing lens parts 4, slide block 7 can drive lens translation together, thus realizes the focusing of light fixture.This focusing structure is simple, and volume is little, and focusing angle is large, and manual zoom is without card.
