The invention provides an observation window and a helicopter, and the observation window comprises a main frame which is used for being connected with a to-be-installed object in a sealing manner, the first side surface of the main frame is recessed inwards to form a sliding groove, and the sliding groove extends from the first end surface of the main frame to the second end surface of the main frame; the side frame is used for being in sealed connection with a to-be-installed object, the first end of the side frame is connected with the first end of the main frame, the first side face of the side frame is concaved inwards to form a fixing groove, one end of the fixing groove communicates with the sliding groove, and the other end of the fixing groove extends to the second end face of the side frame. The window body is rotationally connected with the second end of the side frame in the first direction, the window body and the second end of the side frame rotate forwards and backwards in the first direction, the window body can slide in the sliding groove in a reciprocating mode, and a frame of the window body can be attached to a part of the to-be-installed object when attached to the fixing groove. According to the observation window, the window body is rotationally connected with the side frame, and the window body is slidably connected with the main frame, so that the occupied space is reduced; the main frame is provided with a sliding groove, the side frame is provided with a fixing groove, and liquid accumulation is avoided.
本申请提供一种观察窗和直升机,观察窗包括:主框架用于与待安装物体密封连接,主框架的第一侧面向内凹陷形成滑槽,滑槽从主框架的第一端端面延伸至第二端端面;侧框架用于与待安装物体密封连接,侧框架的第一端与主框架的第一端连接,侧框架的第一侧面向内凹陷形成固定槽,固定槽的一端与滑槽连通,固定槽的另一端延伸至侧框架的第二端端面;窗体与侧框架的第二端绕第一方向转动连接,窗体与侧框架的第二端绕第一方向正反转动,能够使窗体于滑槽内往复滑动,窗体的边框能够贴合于固定槽时贴合部分待安装物体。本申请的观察窗,通过窗体与侧框架转动连接,窗体与主框架滑动连接,减小占用空间;主框架设滑槽,侧框架设固定槽,避免积液产生。
