Изофетение относитс к области авнадионной техники и предназначено дп запирани крышек люков в проемах фюзе-л жей летательных аппаратов.Izofethene belongs to the field of avnadionnoy technology and is designed dp lock the manhole covers in the openings of the fuse-aircraft of the aircraft.

Иаввестны устройства дл запирани крышек люков, содержащие внутренние и наружные ручки, кинематически св аанвые между собой, утопленные в крышки люков или выступающие из них и св занные с подпружиненными штыр ми, вход щими в гнезда, расположенные в окант жке шока. Наружна ручка св зана с за Шрак цими штыр ми тросом.Devices for locking hatch covers, containing inner and outer handles, are kinematically connected to each other, recessed into or extending from the hatch covers and associated with spring-loaded pins that enter the sockets located in the shock window. The outer handle is connected to the Shrak tsimi pins with a cable.

Однако при таком устройстве м№кво за1фьшать крышку грузовоххэ люка только изнутри, дл чехх необходимо оставл ть место дл подхода к ней и что ие дает возможности полностью использовать объем грузйвой кабины самолета. Это также не позвол ет примен ть такую крышку на самолете в качестве входной и грузовой двери.However, with such a device, it should be possible to close the cargo cover of the hatch only from the inside, for the covers it is necessary to leave space for access to it and that it does not allow to fully utilize the volume of the aircraft cabin. It also prevents the use of such a cover on the aircraft as an entry and cargo door.

Цель изобретени - повышение эксплу|атационных качеств обеспечением запирани крышки люка снаружи.The purpose of the invention is to increase the operational qualities by ensuring that the hatch covers are locked from the outside.

Это достигаетс тем, что в предлага емом устройстве на общей оси с осью внутренней ручки закреплен рычаг, с ко торым одним кондом шарнирно соединена жестка т га,, к другому концу которой шарнирно подсоединен подвижно размешенный во втулке наружной ручки шток с пазом, на уровне которого с зазором от штока расположен закрепленный на внешней ручке профилированный кулачок .This is achieved by the fact that, in the proposed device, a lever is attached to a common axis with an axis of the inner handle, with which one condom is rigidly connected to a hinge pin, to the other end of which the rod is movably placed in the sleeve of the outer handle with a groove with a clearance from the rod, a profiled cam mounted on the outer handle is located.

Claims

The hatch cover contains locking pins 1 connected by an axis 2 to a lever 3 fixed rigidly on a tubular axis 4 rotating in chromite 5 mounted on a frame of a hatch. On axis 4 installed. bracket & 6 with springs 7 mounted on the frame of the cover, as well as a lever 8 with a hinge 9 attached to it, which is connected to the lever of the inner handle 10 fixed to the axle 11 rotating on brackets 12 with the other end. 11, a lever 13 is rigidly mounted, hinged but connected to a pull 14, which is connected by an axis 15 to a slot 16 having a groove located in the hub of the housing 17. An outer handle 18 with a cam 19 embedded in it, a lock 2O with a key and a ball lock 21, pivotally mounted on an axis 22 located in the plane and the cover perpendicular to the longitudinal axis of the stem 16. The locking pins 1 are held in the closed position by springs 7 which act on them through the arms 3 and 8 by finding schies on the axis 4, the pins 1 are in nests edging hatch. When the device is opened with the inner handle 1O, the movement is transmitted through cable 9 to pins 1 and through cable 14 to a rod 16 with a groove that moves; 5 I reciprocate in the sleeve of the housing 17. - The groove of the stem 16 is not deformed by the cam 19 of the outer handle due to the presence of a gap between them, and thus, turning the inner handle 10 does not cause the outer handle 18 to move, which does not extend beyond the top of the lid and does not prevent it from moving. relative to the inner surface of the fusell. The device’s detached position is also reached by turning the outer arm 18, the cam 19, which is rigidly connected to it, fits into the groove of the rod 16, thereby providing a connection with the inner handle 10, and through the connecting rods, pins and levers with pins 1. The outer handle 18 is engaged with the rod 16 until the pins 1 are in the position corresponding to the fully open position of the device. The outer handle 18, to engage with the rod 16, has a free wheeling, which allows it to be pulled out of the case for the key of the lock 20 contained therein. From random falling out, the handle 18 is held in the case 17 by a ball lock 21, The lock 20 integrated in the handle 18 allows lock it when the crew leaves the aircraft on the station. Claim device Lock-up hatch cover, containing spring-loaded pins and outer and inner handles, kinematically connected with each other and with pins, characterized in that, in order to increase performance, ensure hatch hatch cover from the outside, in it with a common axis with an axis an inner handle is fixed to a lever with which one end is rigidly connected to a rigid rod, to the other end of which is pivotally connected to a stem with a groove that is movably placed in the sleeve of the outer handle body; eye is fixed to the outside handle profiled cam.
