Description

可调节光束LED灯的调节结构 技术领域
本发明涉及一种LED灯，尤指一种可调节光束LED灯的调节结构。
背景技术
目前出现了一种可以对照射光束的亮度或照射范围进行调节的LED灯，该LED灯一般是在LED的前方设置一个凸透镜，然后通过调节结构调节凸透镜相对LED的距离，以此达到调焦的目的，进而对光束进行调节。
现有技术中，调节结构通常采用螺纹调节方式，还要设置挡位限位结构，以便实现多挡位调节。但是这种调节方式结构不但复杂，而且不易实现无段调节，使用上受到一定局限。
发明内容
本发明所要解决的技术问题在于提供一种结构简单、或实现无段调节的可调节光束LED灯的调节结构。
为解决上述技术问题，本发明的技术解决方案是：
一种可调节光束LED灯的调节结构，所述LED灯的外壳前方固定有LED，该外壳外侧套有一伸缩调节座，该伸缩调节座的外端固定有一凸透镜，该凸透镜位于LED的外侧；所述的外壳与伸缩调节之间设置有一橡胶圈，该橡胶圈与外壳和伸缩调节座之间为过盈配合。
所述的外壳侧壁设有可抵挡伸缩调节座端面的第一限位面，该外壳靠近LED的一端还设有一挡板；所述伸缩调节座的内壁设有可与上述挡板换挡的第二限位面。
所述外壳的外壁设有一销钉，在伸缩调节座上设置有与销钉配合的滑槽。
采用上述方案后，由于本发明在LED灯的外壳与伸缩调节座之间设置了一个橡胶圈，该橡胶圈与外壳和伸缩调节座之间为过盈配合，这样伸缩调节座与橡胶圈之间就存在阻尼现象，需要在外力的作用下才能上下拉动伸缩调节座。这种结构当伸缩调节座拉动到任何位置都能固定限位，从而实现无段调节，而且结构非常简单，操作也非常方便。
附图说明
图1是本发明的剖视图；
图2是本发明止转销钉处的剖视图；
图3是本发明的立体示意图。
具体实施方式
下面结合附图和具体实施例对本发明作进一步详述。
本发明所揭示的是一种可调节光束LED灯的调节结构，如图1、2、3所示，为本发明的较佳实施例。所述LED灯的外壳1前方固定有LED2，该外壳1外侧套有一伸缩调节座3，该伸缩调节座3的外端固定有一凸透镜4，该凸透镜4位于LED2的外侧。
所述的外壳1与伸缩调节3之间设置有一橡胶圈5，该橡胶圈5与外壳1和伸缩调节座3之间为过盈配合，这样伸缩调节座3与橡胶圈5就存在阻尼现象，即需要在外力作用下伸缩调节座3才能上下拉动。
所述的外壳1侧壁还设有可抵挡伸缩调节座3端面的第一限位面11，该外壳1靠近LED2的一端还设有一挡板12。
所述的伸缩调节座3的内壁设有可与上述挡板12换挡的第二限位面31。
本发明在调节时，向外拉动所述的伸缩调节座3，当所述挡板12的底面磁到所述第二限位面31时，停止调节，即调节到最大行程；当回推所述伸缩调节座3，当伸缩调节座3的端面碰到第一限位面11时，调节到最小行程位置。随着伸缩调节座3的位置不同，凸透镜4相对LED2的位置也相应的变化，从而达到调焦的目的。
更进一步的，为了使伸缩调节座3只能上下拉动，而不能左右转动，本发明在外壳1的外壁设有一销钉13，在伸缩调节座3上设置有与销钉13配合的滑槽32，这样即可限制伸缩调节座3转动。
