The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
With reference to Fig. 1, Fig. 2, it is the structural representation of lens focusing structure provided by the invention.Described lens focusing structure, comprise housing 100, be located at adjustable first lens 200 and the second lens 300 in two mutual alignments in housing 100, the axle center of first lens 200 and the second lens 300 is located along the same line, in housing 100, be also provided with an adjusting rod 400, adjusting rod 400 is along the direction setting parallel with first lens 200 and the second lens 300 axis, adjusting rod 400 comprises the knob 420 that has the adjusting portion 410 of external screw thread 411 and drive adjusting portion 410 to rotate, first lens 200 is fixed on a support 500, support 500 is threaded with adjusting portion 410, when adjusting rod 400 rotates, support 500 moves axially along the external screw thread 411 of adjusting portion 410, and drive first lens 200 along the axis direction translation of the second lens 300.In the present invention, in the interior adjusting rod 400 that arranges of housing 100, and drive first lens 200 along the axis moving linearly of base and first lens 300 by the threaded engagement between support 500 and adjusting rod 400, change like this focal length between first lens 200 and the second lens 300, and then changed the focus state of the light being penetrated by first lens 200 and the second lens 300.Above-mentioned focusing structure is simple, and rotation knob 420 gets final product simple realization, focus easy to operate, and said structure is easy to manufacture and assembling, has reduced production cost, has improved production efficiency.
Particularly, with reference to Fig. 2, housing 100 is a tubular structure, in it, along the length direction of its tubular structure, offers a stopper slot 110.As shown in FIG., the second lens 300 are located at the one end of keeping right in stopper slot 110, and first lens 200 is located at the left side of the second lens 300 by support 500.Support 500 is quadrilateral frame shape structure, and it is arranged in stopper slot 110, and one end of quadrilateral frame is provided with an adapter sleeve 520.In adapter sleeve 520, be provided with internal thread (not shown).First lens 200 is located in the inside casing of support 500, and fixing by a trim ring 510.Adjusting rod 400 is located in stopper slot 110 and is positioned at the side that support 500 has adapter sleeve 520, and the adjusting portion 410 of adjusting rod 400 is by passing in adapter sleeve 520, and the external screw thread 411 of adjusting portion 410 and the screw-internal thread fit of adapter sleeve 520, and the two is threaded.Because adjusting rod 400 is fixed in the axial direction in stopper slot 110, when driving adjusting rod 400 rotation by rotation knob 420, under the drive of the external screw thread 411 of adjusting rod 400, under twisting effect, along adjusting rod 400, move axially with the adapter sleeve 520 of adjusting rod 400 threaded engagement, support 500 and first lens 200 provided thereon move under adapter sleeve 520 drives, thereby changed the focal length between first lens 200 and the second lens 300, realized the effect that light regulates.
Further, in stopper slot 110 and be arranged in first lens 200 away from a side of the second lens 300 as the left side of figure first lens 200 is also provided with a flat glass mirror 600.Flat glass mirror 600 plays the effect of spacing first lens 200 on the one hand, departs from stopper slot 110 while avoiding it to move, and it can see through by facial expression line on the other hand, also can play regulating action to light.
Further, on flat glass mirror 600, be arranged with beam 700.Like this, by beam 700 is set, play iris action on the one hand, while avoiding first lens 200 to move, directly touch with flat glass mirror, also strengthened on the other hand the shockproof effect of whole housing 100.
As one embodiment of the invention, housing 100 is formed by the upper shell 120 and lower house 130 docking that are all halfpipe structure, particularly, please refer to Fig. 2, Fig. 3, upper shell 120 and the interior correspondence of lower house 130 are provided with installing hole 121 and 131, by being combined on screw 140 in corresponding installing hole 121 and 131, upper shell 120 and lower house 130 are connected in one and form housing 100.In the present embodiment, one end that upper shell 120 is corresponding with lower house 130 is equipped with the external screw thread 122 and 132 that can externally connect, this external screw thread 122 and 132 is all located on halfpipe structure outer wall, when upper shell 120 docks formation one pipe with lower house 130, external screw thread 122 and 132 pieces together a complete external screw thread, and it can externally connect.In the present embodiment, the external screw thread that this can externally connect being set, is using above-mentioned lens focusing structure as an individual components, after its assembling can being completed, is installed on outside manufacture again, like this, has facilitated assembling and maintenance, has improved efficiency.
Further, in the present embodiment, for avoiding extraneous dust, foreign material to enter in housing 100, upper shell 120 is provided with rib 123 with lower house 130 joints, and is provided with baffle plate 124 in upper shell 120.
Further, in the present embodiment, upper shell 120 is also provided with a breach 125, on lower house 130, corresponding position is provided with another breach 133, after upper shell 120 is connected with lower house 130, two breach form an opening and are exposed to outside housing 100 for knob 420, like this, and person's operation knob easy to use portion 420.
The present invention also provides a kind of light fixture, the lens focusing structure that it comprises lamp housing, is located at the light source in lamp housing and can focuses to light source, and described lens focusing structure is identical with said structure, does not repeat herein.Need explanation, lamp housing is provided with connecting portion, is connected with external screw thread 122,132 on housing 100 in said lens focusing structure, and like this, lens focusing structure, is convenient to assembling and is keeped in repair as integral installation independently on lamp housing, has greatly improved efficiency.Certainly, herein, housing 100 also can be a part for lamp housing, and said lens focusing structure is directly located in lamp housing.Specific design form, selects according to actual needs flexibly.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
