Example Embodiment

[0017] The use of this invention will be described in further detail below. A lock key 1 is provided on the handle 2, and when the window is closed, the dead bolt 3 snaps into the lock disc 5 under the action of the torsion spring 4 to realize the handle locking. Press the lock button 1 when opening the window, and the lock button 1 pries the dead bolt 3 to eject the lock disc 5 to realize unlocking.

[0018] After the handle 2 is unlocked, it rotates clockwise. The handle 2 is fixedly connected with the lock hook 10. The rotation of the handle 2 drives the lock hook 10 to rotate clockwise. It is connected with the rocker arm 22 through the torque tube 21, the rocker arm 22 is connected with the rocker arm 24 through the link assembly 23 to form a four-bar linkage mechanism, and the rocker arm 24 and the rocker arm 26 are connected through the link assembly 25 to form a four-bar linkage mechanism, three groups The four-bar linkage conveys the rotation of the handle to four lo...

Abstract

The invention pertains to the design of cockpit ventilation windows, relating to a multi-functional bird collision resistant ventilation window. A locking key and a locking bolt are arranged on a handle, the locking key is jointed with one end of the locking bolt, the upper surface of the locking bolt is jointed with a torsional spring, and the other end of the locking bolt is jointed with a lockhole on a lock tray; the handle is fixedly connected with a front lower latch hook, the external end of the front lower latch hook is jointed with a lock column, the middle point of the front lower latch hook is connected with the middle point of a rear lower latch hook by a connecting rod component, the inner end of the front lower latch hook is connected with a roller wheel component, the roller wheel component is blocked into a lower slideway, the rotating shaft of the rear lower latch hook is connected with a rocker arm by a torque tube, the external end of the rear lower latch hook is jointed with the lock column, the inner end of the rear lower latch hook is fixedly connected with the roller wheel component, the roller wheel component is blocked into the lower slideway, a rear upper rocker arm is connected with the rocker arm by the connecting rod component, the inner end of a rear upper latch hook is fixedly connected with an upper roller wheel component, and the upper roller wheel component is blocked into an upper slideway. In respect of the ventilation window, a set of mechanism is added in the handle and an outboard unlock function is added on basis of the bird collision resistance of the ventilation window, thus ensuring higher safety and reliability of the mechanism.

Description

technical field [0001] The invention belongs to the design of a ventilation window of a cockpit, and relates to a multifunctional anti-bird strike ventilation window. Background technique [0002] According to airworthiness regulations, when the inclined angle of the curved surface of the ventilation window is greater than or equal to 15 degrees relative to the longitudinal axis of the aircraft, the ventilation window must be able to withstand the impact of a 1.8 kg (4 lb) bird at the aircraft's design cruising speed without being broken down. At the same time, the design of the ventilation window must meet the functions of sealing, smooth movement of the mechanism, locking and unlocking, etc. At present, the design of ventilation windows in China is almost blank, and the design technology of ventilation windows of foreign mainline aircraft is relatively mature, but all anti-bird strike ventilation windows cannot realize the function of unlocking outside the aircraft.
