The utility model relates to a boresight adjustment mechanism, which comprises a substrate, a mounting plate, base plate and the mounting plate is arranged in parallel, the front end of the mounting plate and the substrate mounted hinge by a hinge shaft connected to the mounting plate is connected with the base plate by screws, the screws of a coaxial set upper adjusting sleeve, the adjustment the screw sleeve is connected with the lower end portion of the mounting plate screw, screw thread connected with the substrate. This line of sight adjustment mechanism using coaxial adjustment screw to adjust the screw axis, and the screw press the top opening role of the two is coincidence, clamping force and screw sleeve supporting force offset adjustment screw in the fastening process, after the adjustment, the mounting plate and the substrate is not deformed. Can be reliably fixed. The coaxial adjusting screw can be used only by one set, which can save the adjustment time and reduce the cost.
【技术实现步骤摘要】
本技术属于视频安防监控领域,尤其是一种视轴调整机构。
技术介绍
随着科学技术的发展,人们对视频监控产品的性能也不断提高。目前,经常将摄像机与红外成像仪、红外光辅助照明、红外激光发生器等辅助照明设备配合使用。因此必须保证安装在同一监控产品上的摄像机和辅助照明设备的视轴或光轴相互平行或者交于一点,所以监控产品中均需一套视轴调整机构。传统的视轴调整机构包括基板和安装板,安装板与基板平行设置,并通过安装板一端部的铰轴与基板连接,安装板的另一端部安装有两个调整螺钉10来调整安装板与基板之间的夹角,如图4所示,调整完毕后通过位于两个调整螺钉外侧的紧固螺钉11将安装板与基板连接在一起。这种视轴调整机构的缺点在于:由于两个调整螺钉之间存在一定的中心距,必然造成安装板与基板的形变,如图4所示,该形变使得紧固螺钉松动,从而会导致安装板与基板之间的角度发生变化,最终直接影响监控产品的成像质量。
