The invention discloses a rainy day self-closing type window. The window comprises a window frame and a mounting frame arranged in the window frame in a rotating mode; glass is arranged in the mounting frame; two first movable rods are symmetrically connected to the lower end of the window frame in a rotating mode; a second movable rod is connected to the end, far away from the window frame, of each first movable rod in a rotating mode; the other ends of the two second movable rods are connected to the mounting frame in a rotating mode; two placement grooves are symmetrically formed in the lower end of the window frame; each placement groove is divided into a heating cavity and a transmission cavity through a partition plate; a circulating mechanism is arranged in each heating cavity; a mounting groove is further formed in the window frame; and a trigger mechanism is arranged in the mounting groove. According to the window, during sudden heavy rainfall outdoors, through the cooperationof the trigger mechanism, the circulating mechanisms, linkage mechanisms and clamping mechanisms, the mounting frame and the window frame can be quickly closed without manual operation, so that rainwater is prevented from falling down into a room, in addition, the window can be repeatedly used, and the practicability is strong.

The invention relates to an outside-sealed displacement adjusting mechanism for a parallel-connection spray pipe, and relates to a combined engine tail spray pipe. The outside-sealed displacement adjusting mechanism for the parallel-connection spray pipe is provided with an actuator cylinder, a connecting rod, a rocker arm, a fixed hinge, a long sliding block, a long sliding block cam shaft, a spray pipe side plate, a spray pipe intermediate diaphragm, a spray pipe upper wall surface, a splitter plate and a spray pipe lower wall surface. The actuator cylinder can move left and right; the rocker arm rotates around the fixed hinge; a through hole is formed in the lower end of the rocker arm; the long sliding block cam shaft can move in the hole; a side plate slot is formed in a spray pipe side wall; a through hole is formed in the center of the slide plate slot; the long slide block can slide in the side plate slot; the length of the long sliding block is larger than the length of the through hole of the side plate slot, so that during a sliding process of the long sliding block, the sliding block can always cover the through hole of the side plate slot, and a sealing effect is achieved; the long sliding block cam shaft is arranged at positions, on two sides of the side plate, on the long sliding block; the long sliding block cam shaft on the outer side of the side plate is connected with the rocker arm through the through hole; and the long sliding block cam shaft on the inner side of the side plate is connected with the splitter plate through a splitter plate sliding chute.An air flow state of a spray pipe outlet can be improved, and better thrust performance is obtained.
