请结合参阅图1及图2，本发明提供一种镜头固定与调节装置100， 用于固定镜头200并调节镜头200的位置，该镜头固定与调节装置100具体可以应用于投影设备，如影院投影仪或者工程投影仪等。其中，镜头200包括安装柱面210以及辐板220，辐板220环绕部分安装柱面210设置，具体可以是环绕该安装柱面210的外周进行设置，且辐板220的外径大于安装柱面210的外径。
镜头固定与调节装置100包括底板10、固定组件以及调节组件50。
固定组件可移动地设置于底板10上，用于固定安装镜头200；调节组件50固定设置于底板10上，并位于固定组件的一侧，用于调整固定组件的位置，进而调整镜头200的位置。
具体的，固定组件包括支撑件31、第一压板32以及第一紧固件33。
支撑件31可移动地设置于底板10上，具体而言，请结合参阅图3，支撑件31包括基板311，基板311贯通开设有定位孔312，定位孔312为腰型孔，定位孔312沿镜头200的轴向方向延伸，底板10上凸设有固定柱11，固定柱11容置于定位孔312内，以在调节组件50的驱动作用下，起到导向作用。
其中，固定柱11可以通过螺纹或卡接等方式固定在底板10上，或者固定柱11与底板10一体成型。
本实施方式中，基板311上贯通开设有两个定位孔312，两个定位孔312之间的连线与镜头200的轴向方向平行。当然，在其它实施方式中，定位孔312的数量、固定柱11的数量可以根据需求进行相应的调整，在此不作限定。
进一步的，支撑件31还包括垂直设置于基板311上的支撑板313，支撑板313开设有安装孔314，镜头200穿过安装孔314使得安装柱面210与安装孔314的内壁贴合，而辐板220的一侧与支撑板313的表面紧贴设置。且辐板220的另一侧与第一压板32的表面紧贴设置，其第一压板32与支撑件31，具体与支撑板313固定配合，从而将辐板220夹持固定于第一压板32与支撑板313之间。
在具体实施例中，第一压板32可以固定设置于支撑板313上，第一压板32朝向辐板220的一侧的内环形成有收容槽321，从而使得镜头 200的辐板220可以收容于收容槽321中，以通过第一压板32将镜头200固定设置于支撑板313上。
本发明实施方式中，第一压板32上开设有多个第一装配孔322，支撑件31上开设有多个第一配合孔315，多个第一配合孔315围绕安装孔314设置，多个第一配合孔315与多个第一装配孔322一一对准，以将第一紧固件33依次旋入第一装配孔322、第一配合孔315而将第一压板32固定设置于支撑板313上。本实施方式中，第一装配孔322、第一配合孔315均为螺纹孔，第一紧固件33为螺钉。
本实施方式中，第一压板32呈半环状。
当然，在其它实施方式中，第一压板32还可以是其它的形状，如可以是环绕该辐板220设置的压块，其优选为至少两个且靠着该辐板220的底部设置，其同样可以设置有收容槽，一方面可以收容辐板220，并支撑于固定该辐板220，从而将镜头200固定于支撑板313上。

可以理解，在支撑件31与第一压板32之间设置一层垫片34，既能稳固地将镜头200安装在支撑件31上，又能够保持夹持柔性，有效防止镜头200在受到振动后发生松动或相对转动，提高装配稳定性。
进一步的，请结合参阅图3及图4，基板311的下表面凸设有凸台316，支撑件31通过凸台316与底板10连接。本实施方式中，基板311 的下表面凸设有两个凸台316，两个凸台316设置于基板311的两侧，凸台316的延伸方向与镜头200的轴向方向相同。
可以理解，通过在基板311的下表面设置凸台316，能够避免支撑件31的基板311的整个底表面与底板10接触，便于控制支撑件31与底板10之间的滑动，从而确保移动的精度。
进一步的，固定组件还包括第二紧固件35，基板311上贯通开设有第二装配孔317，底板10上开设有第二配合孔12，第二装配孔317为腰型孔，以通过第二紧固件35将支撑件31固定设置于底板10上。
可以理解，第二装配孔317的延伸方向与镜头200的轴向方向平行，第二配合孔12为螺纹孔，第二紧固件35为螺钉，以使第二紧固件35穿过第二装配孔317并旋入第二配合孔12，从而使得第二紧固件35的一端固定设置于底板10上，而基板311可以相对第二紧固件35滑动。
本实施方式中，第二装配孔317开设于基板311上设有凸台316的区域，每一凸台316上贯通开设有两个第二装配孔317。
进一步的，支撑板313上间隔设置有多个加强筋318，多个加强筋318相邻且垂直的两边分别与支撑板313及基板311固定连接，以便于承受重量较大的镜头200，加强筋318可以是三角形或者梯形。
请参阅图5及图6，调节组件50设置于支撑件31的一侧，调节组件50包括动力件51、调节座52、调节件53、第二压板54、第三紧固件55以及第四紧固件56。
动力件51用于提供驱动力。本实施方式中，动力件51可为但不限于为电机。
调节座52固定设置于底板10上，调节座52贯通开设有阶梯孔521，阶梯孔521的轴向方向与镜头200的轴向方向平行。
本实施方式中，调节座52的两侧凸设有安装部522，安装部522上开设有第三装配孔523，底板10上开设有第三配合孔13，通过将第三紧固件55依次旋入第三装配孔523及第三配合孔13，而将调节座52固定设置于底板10上，其中，第三装配孔523及第三配合孔13均为螺纹孔，第三紧固件55为螺钉。
调节件53容置于阶梯孔521内，且调节件53的一端与动力件51连接，另一端与支撑件31连接，以在动力件51的驱动作用下驱动支撑件31在底板10上移动。
请结合参阅图6，调节件53包括本体部531及端部532，阶梯孔521包括第一通孔5211及第二通孔5212，第一通孔5211的外径大于调节件53端部532的外径，第二通孔5212的内径大于调节件53本体部531的外径且小于调节件53端部532的外径，如此就可以将调节件53的端部532收容于第一通孔5211内，而本体部531穿过第二通孔5212与支撑件31连接，从而调整支撑件31的位置，进而调整镜头200的位置。本实施方式中，第二通孔5212位于靠近固定组件的一侧，调节件53为螺钉，例如内六角头螺钉，进一步的，可以是M6的内六角头螺钉。
进一步的，请再次参阅图4，基板311上凸设有凸起部319，凸起部319朝向调节组件50的侧面开设有连接孔320，调节件53的本体部531远离端部532的一端与连接孔320连接。本实施方式中，连接孔320为螺纹孔，使得调节件53与支撑件31螺纹连接。
第二压板54固定设置于调节座52远离固定组件的一侧，第二压板54开设有圆孔541，圆孔541与阶梯孔521对准，且圆孔541的孔径小于调节件53的端部532的外径，以将调节件53的端部532封闭在第一通孔5211中，如此，动力件51驱动调节件53旋转时，调节件53的本体部531旋转而驱动支撑件31移动。
其中，第二压板54上开设有多个第四装配孔542，调节座52上开设有第四配合孔522，通过将第四紧固件56依次旋入第四装配孔542及第四配合孔522，以将第二压板54固定设置于调节座52上。本实施方式中，第四装配孔542及第四配合孔522均为螺纹孔，第四紧固件56为螺钉。
可以理解，通过将第二压板54设置于调节座52远离固定组件的一侧，且圆孔541的直径小于调节件53的端部532的外径，进一步的，动力件51的输出端可以穿过该圆孔541与调节件53的端部532连接，一方面可以驱动该调节件53进行旋转，另一方面，可以将调节件53的 端部532封闭在第一通孔5211内，动力件51驱动调节件53旋转时，调节件53的端部532只能在第一通孔5211内旋转，而不会在轴向方向上移动，如此，就可以通过调节件53本体部531驱动支撑件31移动。
可以理解，调节组件50设置于固定组件的一侧，整个装置所占的空间并没有超出镜头200本身所占的空间太多，空间利用率高，便于投影设备中的布局以及安装。
现有技术中通常采用螺杆来进行调节镜头200的位置，然而螺杆的大多数由钢材制成，支撑件以及对螺杆限位的支架的材质通常会选用铝合金或者镁合金，螺杆和支架的材质强度和硬度差异很大，在发生相对运动时支撑以及对螺杆限位的支架常常会承受较大的磨损作用，经过支架与螺杆之间的不断摩擦，可能导致螺杆在支架中脱开，使得投影设备无法正常工作。而本发明实施方式中，调节件53封装于调节座52的内部，能够避免支撑件31与调节件53发生较大的摩擦而出现调节件53脱落的现象，且调节座52的材料选用钢制材料，能够有效减少磨损，进一步的，依靠螺钉旋转调节距离的方式大大提高了调节精度，并且所需物料简单或为通用标准件，容易获得、成本低。
进一步的，请再次参阅图1，镜头固定与调节装置100还包括测距组件70以及处理器90，测距组件70用于检测镜头200到投影屏幕之间的距离并将此距离信号发送至处理器90；处理器90通过对该距离信号进行分析处理后，向动力件51发送相应的控制驱动信号，由于动力件51与调节件53直接连接，如此，动力件51就可以根据驱动信号驱动调节件53，直至将镜头200调节至合适位置使得投影图像呈现出清晰的画面。动力件51可以是步进电机、伺服电机等。
区别于现有技术，本发明实施方式提供的镜头固定与调节装置100通过将镜头200的辐板220夹设于支撑件31与第一压板32之间，且第一压板32固定设置于支撑件31上，如此通过辐板220与第一压板32将辐板220挤压并固定，即使镜头200上未开设固定孔也能够稳固地安装于支撑件31上，且该镜头固定与调节装置100结构简单、所占空间较小、通用性较强。
本发明还提供一种投影设备(未图示)，该投影设备包括镜头固定与调节装置，镜头固定与调节装置与上述所述的镜头固定与调节装置100的结构相同，在此不再赘述。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明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，均同理包括在本发明的专利保护范围内。
