Detailed description of the invention
In conjunction with accompanying drawing, presently preferred embodiments of the present invention is elaborated.
As illustrated in fig. 1 and 2, a kind of pocket lamp being easy to focusing of the first embodiment that the present invention provides, the cylinder 200 including stack shell 100, being internally provided with lens 210, the lamp socket 300 being internally provided with lamp source 310 and focusing component 400.Focusing component 400 includes rotating ring 410 and fixture 420, and the outer wall of fixture 420 is provided with waveform groove 421, and waveform groove is arranged on the outer wall of fixture 420 can facilitate the processing of waveform groove 421.The inwall of rotating ring 410 is provided with guide pillar 411, and rotating ring 410 is set in outside fixture 420, and one end of guide pillar 411 is placed in waveform groove 421.Cylinder 200 is arranged on lamp socket 300 by focusing component 400, and lamp socket 300 is installed on stack shell 100, by rotating rotating ring 410, makes cylinder 200 move along pocket lamp axial reciprocating relative to lamp socket 300.So lamp socket 300 avoids the need for and has relative motion between stack shell 100, so lamp socket 300 can be in close contact with stack shell 100, guarantee that heat can be conducted to stack shell and dispel the heat by lamp socket 300 in time, it is to avoid the problem that in lamp socket 300, the temperature too high life-span affecting lamp source 310 or restriction high-power lamp source 310 use.
In the present embodiment, guide pillar 411 has two, and is symmetrical arranged, and so can make the rotation that rotating ring 410 can be stable.Waveform groove 421 has two crests and two troughs are optimal, wavelength can be set according to actual needs, can realize being condensed to gradually changing of astigmatism in guaranteeing the cycle of a crest and trough, i.e. rotating ring 410 revolves turnback and just can realize from the focusing being condensed to astigmatism, is suitable for the rotational angle of human body wrist.In other embodiments, waveform groove 421 can also select crest and the trough of other quantity.
One end of fixture 420 is threadably secured with cylinder 200 and is connected, and the other end axially movably can be set on lamp socket 300 along pocket lamp, and rotating ring 410 is fastened on lamp socket 300 rotationally.By rotating rotating ring 410, guide pillar 411 is made to move in waveform groove 421, the waveform connect due to WEILIAN headed by waveform groove 421, so rotating ring 410 drives cylinder 200 to move along pocket lamp axial reciprocating relative to lamp socket 300, makes lens 210 in cylinder 200 change with the distance in lamp source 310.
Specifically, the other end of fixture 420 protrudes and is formed with guide pad 422, and the outer wall of lamp socket 300 offers the gathering sill 320 matched with guide pad 422.Gathering sill 320 axially offering along pocket lamp, such fixture 420 can only moving axially along pocket lamp.
In other embodiments, the inwall of fixture 420 protrudes and is formed with guide pad 422, and the outer wall of lamp socket 300 offers the gathering sill 320 matched with guide pad 422.Gathering sill 320 axially offering along pocket lamp, the most also can realize fixture 420 and can only move axially (as shown in Figure 3) along pocket lamp.
In other embodiments, the inwall of fixture 420 offers gathering sill 422 ', and the outer wall of lamp socket 300 offers the guide pad 320 ' matched with gathering sill 422 '.Gathering sill 422 ' axially offering along pocket lamp, the most also can realize fixture 420 and can only move axially (as shown in Figure 4) along pocket lamp.
When needs flashlight is focused, first rotate rotating ring 410, and then make guide pillar 411 move in waveform groove 421, under the guide pad 422 effect with gathering sill 320, cylinder 200 moves along pocket lamp axial reciprocating relative to lamp socket 300, i.e. distance between lens 210 and lamp source 310 changes, thus realizes focusing.The most also can reach to guarantee that lamp socket 300 dispels the heat in time and is easy to the purpose of focusing.Further, since cylinder 200 is parallel mobile mode, so the quantity in lamp source 310 can have two or more.
It addition, guide pillar 411 is placed in waveform groove 421, such rotating ring 410 is not limited by rotation direction, it is possible to both forward and reverse directions unlimited rotary is focused, and is greatly improved the convenience of focus operations.Above-mentioned focusing structure is simple, it is simple to production and processing and assembling.
Specifically, in order to facilitate the installation of guide pillar 411, guide pillar 411 is screw, and rotating ring 410 offers screw 412.Screw 411 protrudes from the inwall of rotating ring 410 through screw 412, is placed in waveform groove 421.Further, screw 411 is placed in one end of waveform groove 421 and is additionally provided with rolling ring, so can reduce the frictional force between guide pillar 411 and waveform groove 421, and make that guide pillar 411 moves is more smooth and easy.
In other embodiments, rotating ring 410 is fixing with cylinder 200 to be connected, and fixture 420 is fixing with lamp socket 300 to be connected.The focusing between rotating ring 410 and fixture 420 can also be realized by rotating cylinder head 200.
It should be appreciated that above example is only in order to illustrate technical scheme, it is not intended to limit, it will be understood by those skilled in the art that the technical scheme described in above-described embodiment can be modified, or wherein portion of techniques feature is carried out equivalent；And all such modifications and replacement, all should belong to the protection domain of claims of the present invention.
