其中，基座101、调节支架103、透镜支架106依序设置，透镜支架106设有安装透镜105的区域，调节支架103上设有旋转支点111，透镜支架106在其安装透镜105的区域之外设有旋转连接点112，透镜支架106以旋转连接点112连接于旋转支点111，可绕旋转支点111转动；调节支架103以及与其可转动连接的透镜支架106通过第一方向调节组件100相对于基座101在第一方向位置可调，通过第二方向调节组件200，使得透镜支架106相对于调节支架103绕旋转支点111转动，转动方向的至少一分量为第二方向。
本实施例的透镜调节装置使用调节组件和旋转组件(包括旋转支点以及旋转连接点)取代了通常所用的导轨，调节透镜105的位置。透镜105安装于透镜支架106上，透镜支架106与调节支架103间可旋转地 连接，当调节支架103在第一方向调节组件100的带动下向第一方向位移时，会带动透镜支架106一同在第一方向上运动，完成第一方向上的位置调节。第二方向调节组件200则对透镜支架106施加转动力矩，使透镜支架106相对于调节支架103以旋转支点111为中心进行转动。
旋转支点111设置于安装透镜105的区域之外，避免转动力矩过小，透镜支架106转动后的位移过小甚至在原地转动。透镜支架106的转动与在第一方向上的位移为同一平面，使得转动方向的其中一个分量和第一方向相同，另一分量与第一方向垂直，该垂直方向即为透镜105调节的第二方向。由于第二方向上的位置调整是相对旋转中心产生，因此该调整伴随着弱第一方向的位置调整，透镜支架106的转动使其同时在第一方向和第二方向进行了移动，但主要是为调节第二方向的位置，通过较少次数的调整即可准确定位透镜105。以下将对第一方向调节组件100、第二方向调节组件200及旋转组件的结构做具体说明。
请参阅图3至图5，图4和图5分别为调节支架103和透镜支架106的结构图，本实施例中的旋转支点111是调节支架103上的第一通孔，旋转连接点112是透镜支架106邻近调节支架103一侧凸起的定位柱；或旋转支点111是透镜支架106上的第一通孔，旋转连接点112是调节支架103邻近透镜支架106一侧凸起的定位柱；其中，定位柱与第一通孔配位设置，即，当调节支架103和透镜支架106安装贴合时，定位柱位于第一通孔中。透镜支架106和调节支架103的主体均为平面板状，安装时两者相贴合，两者在接触面上通过旋转组件进行连接，本实施例中旋转组件为定位柱和第一通孔，定位柱或第一通孔两者可任意选择设置于透镜支架106或调节支架103上，均可以达到使透镜支架106相对调节支架103转动的效果，从而完成透镜支架106在第二方向上的位移。
本实施例中的第一方向调节组件100和第二方向调节组件200对应设置于基座101的同侧。第一方向调节组件100和第二方向调节组件200设于基座101的同一侧，这样在使用时即可在一侧调节透镜位置，避免了常见透镜调节装置在受阻空间范围内不易实现两个方向同时调整的缺陷。
本实施例中的基座101包括基板113以及分别位于基板113两相对侧的第一侧壁114和第二侧壁115，第一侧壁114上设有第二通孔，还包括从调节支架103对应第一侧壁114的一端向靠近透镜支架106方向水平延伸出的第一安装板1031，在第一安装板1031上对应第二通孔处设有第三通孔；第一方向调节组件100包括穿过第二通孔和第三通孔的第一紧固螺钉108，套设于第一紧固螺钉108上的弹簧109以及螺母110，且弹簧109设于调节支架第一安装板1031和第一侧壁114之间。调节支架103与基座101之间通过第一紧固螺钉108连接，第一紧固螺钉108上由螺母110锁定，通过调节螺母110就可以使调节支架103上下运动，该上下的方向即为透镜105调节的第一方向。第一安装板1031位于调节支架103的顶部，与第一侧壁114相平行，用于将调节支架103与基座101连接。
本实施例中的第二侧壁115在面向第一侧壁114的一侧设有导向柱116，调节支架103还包括从调节支架103对应第一侧壁114的一端向靠近透镜支架106方向水平延伸出的限位板1032，在限位板1032上设有第一定位孔1033。第一定位孔1033与导向柱116配位设置。调节支架103的上端通过第一紧固螺钉108与第一侧壁114连接，下端通过导向柱116和第一定位孔1033进行限位，使调节支架103稳固地设置于基座101内。调节支架103的长度小于第一侧壁114和第二侧壁115之间的距离，螺母110向上调节时弹簧109受到一定压缩，对调节支架103产生向下的弹力，同时弹簧109本身也具有一定的长度，因此使下部的限位板1032在使用过程中不能从导向柱116上脱离，保证了调节支架103两端的稳定性。
本实施例中的第二方向调节组件200包括从调节支架103向靠近透镜支架106一侧横向延伸出的第二安装板1034、从透镜支架106的对应位置同向延伸出的第三安装板120以及穿过第二安装板1034和第三安装板120的第二紧固螺钉121以及第二螺母124，调节第二螺母124对透镜支架106施加转动力矩，使透镜支架106绕旋转支点转动。第二安装板1034和第三安装板120分别垂直于调节支架103和透镜支架106， 两者可以是独立焊接于调节支架103和透镜支架106上的板，也可以是先对调节支架103和透镜支架106切割，然后折弯90度形成的钣金件。第二安装板1034和第三安装板120上设有对应的螺钉孔，第二紧固螺钉121从该螺钉孔内穿过，下部由第二螺母124锁紧。当旋动第二螺母124时，由于调节支架103固定于基座101上，因此第二螺母124和第二紧固螺钉121带动透镜支架106运动，对透镜支架106施加了转动力矩。透镜支架106绕旋转支点111进行转动，透镜支架106的转动产生一部分横向位移和一部分竖向位移，该横向位移方向即为透镜105调节的第二方向。透镜支架106的转动同时在第一方向和第二方向进行了移动，但主要是为调节第二方向的位置，第一方向的位移变化为微小的变化，在此可以忽略。
本实施例中的第二安装板1034和第三安装板120分别设于调节支架103和透镜支架106的竖向中心线的一侧，第二安装板1034和第三安装板120为第二紧固螺钉121和第二螺母124提供安装支点，第二紧固螺钉121和第二螺母124为透镜105提供转动力矩，因此不能设置于中心线上，会导致力矩为零，无法使透镜支架106转动，也就无法调节透镜105的位置。
本实施例中的透镜调节装置还设有紧固装置，包括第三紧固螺钉102和紧固件107；基板113、调节支架103和透镜支架106对应位置处均设有安装孔122，第三紧固螺钉102从一侧依次穿过安装孔122，紧固件107于另一侧将调节支架103和透镜支架106固定于基板113上。调节支架103和透镜支架106在平面方向上固定于基座101上，紧固装置用于两者垂直面上的固定，通过第三紧固螺钉102和紧固件107将调节支架103和透镜支架106固定于基座101的基板113上，使调节支架103和透镜支架106无法在垂直面上运动。优选的，调节支架103和透镜支架106的安装孔122均为腰型孔，腰形孔为两端是半圆弧，中间是平行平面的通孔，当透镜支架106转动时，两个安装孔122之间形成夹角，使透镜支架106有转动空间。
如图3和图4所示，本实施例中的透镜105通过透镜弹片104固定 于透镜支架106上，调节支架103上与安装透镜105的区域对应位置设有第四通孔123，透镜弹片104和透镜105容纳于第四通孔123内；基座101对应第四通孔123处设有第五通孔125。透镜弹片104为环形固定件，透镜105安装于环形中间，透镜弹片104通过螺栓与透镜支架106固定。第四通孔123开设与调节支架103下部，直径大于或接近于透镜弹片104外边缘的直径，使之可以容纳透镜弹片104。第五通孔125正对第四通孔123内的透镜105，为透镜调节装置的出光孔。
使用本实用新型的透镜调节装置，使用第一方向调节组件使调节支架在一个方向上产生位移，从而带动透镜支架在该方向上同步位移，通过调节支架底部的导向柱和定位孔的配合限定位移的方向；第二方向调节组件向旋转组件施加一个力矩，使旋转组件带动透镜支架和透镜旋转，旋转的一个分量形成与第一方向调节组件带动透镜支架运动方向垂直的另一方向上的移动，第一方向调节组件、第二方向调节组件以及旋转组件三者结合进行透镜不同方向上的位置调节，取代了常用的导轨或滑轨的调节结构，结构简单，降低制造成本且便于操作；
且第一方向调节组件和第二方向调节组件设置于透镜同侧，满足透镜在一侧调整不同方向的使用需求。
以上所述仅为本实用新型的实施方式，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围内。
