Adjustment mechanism for airplane ventilating window

Abstract

The invention provides an adjustment mechanism for an airplane ventilating window, comprising an upper adjustment mechanism, a front lower adjustment mechanism and a back lower adjustment mechanism, wherein each adjustment mechanism comprises a rocker arm, a bolt and an idler wheel component. 1mm of the eccentricity is available between the centre line of an idler wheel installing shaft in each adjustment mechanism and the centre line of each corresponding external spline shaft, and the position of a front lower idler wheel is adjusted by rotating a lower idler wheel rotating shaft, so that a ventilating window body can be driven to move, and the distance between the ventilating window body and a lower sliding rail can be adjusted. An installing groove for an adjusting gasket is respectively arranged between the installing shaft and the external spline shaft in each idler wheel component. According to the adjustment mechanism, the ventilating window moving gap can be adjusted by increasing and reducing the quantity of the gaskets of the upper adjustment mechanism and the lower adjustment mechanism; the gaps among the window body, an upper window frame and a lower window frame can be further adjusted by increasing and reducing the quantity of the gaskets of the lower adjustment mechanism; and the idler wheel components are rotated, and the eccentric degree of the splines are changed, so that the adjustment of the jump, the opening and the closing force and the air impermeability of the window body can be realized, the workload can be reduced, and the labor and the time can be saved.

Description

technical field [0001] The invention relates to the field of aircraft design, in particular to an adjustment mechanism for an aircraft ventilation window. Background technique [0002] The ventilation window is a channel for the cockpit to ventilate the cockpit, communicate with the ground crew and have a wider view when the aircraft is in a stopped state. Existing ventilation window is generally made up of two parts of slide rail and ventilation window, and slide rail is positioned by frock, and after positioning is finished, ventilation window is installed between slide rail. If the ventilation window has problems such as poor movement clearance, window steps and gaps that do not meet the requirements, unsatisfactory opening and closing force, or poor airtightness, it will take a lot of manpower and time to adjust. In order to solve the above problems, it is necessary to design a mechanism that can adjust the movement gap, window step and gap, opening and closing force an...
