Detailed Description
Referring to fig. 1-4, the present invention provides a helicopter door with a self-locking mechanism for a movable window, comprising: a helicopter cabin door panel having a movable window; the movable window assembly sliding rail is arranged on the door plate of the helicopter cabin door and used for installing the movable window; the fixed rack is arranged on the door plate of the helicopter cabin door; one end of the spring is connected with the movable window; and the push-pull rod is provided with a push-pull rod rack and is connected with the other end of the spring.
When the movable window needs to be opened, the push-pull rod is pressed by a hand and pulled to one side, the spring is stressed and compressed, and when the rack of the push-pull rod is separated from the fixed rack, the movable window can be opened; when the movable window needs to be opened to a certain position, the push-pull rod is released, the pull rod rack is pushed to be meshed with the fixed rack under the action of the elastic force of the spring, and the movable window is locked.
In other embodiments of the present application, the helicopter door further comprises: and the push-pull handle is arranged on the push-pull rod.
When the movable window needs to be opened, the push-pull handle is pressed by a hand and pulled to one side, the spring is stressed and compressed, and when the push-pull rod rack is separated from the fixed rack, the movable window can be opened; when the movable window needs to be opened to a certain position, the push-pull handle is released, the pull rod rack is pushed down to be meshed with the fixed rack under the action of the elastic force of the spring, and the movable window is locked.
In other embodiments of the present application, the present application provides a helicopter door comprising a helicopter door panel 1, a movable window assembly sliding rail 2, a movable window 3, a handle mounting bolt 4, a first fixed rack 5 on the upper part of the inner side of the movable window, a second fixed rack 6 on the lower part of the inner side of the movable window, a push-pull rod 7, a push-pull handle 8, a handle mounting nut 9, a spring 10, a push-pull rod rack 11, and a fixed rack internal tooth 12.
The movable window assembly comprises a movable window assembly sliding rail 2, a movable window 3, a handle mounting bolt 4, a fixed rack 5 at the upper part of the inner side of the movable window, a fixed rack 6 at the lower part of the inner side of the movable window, a push-pull rod 7, a push-pull handle 8, a handle mounting nut 9, a spring 10, a push-pull rod rack 11 and fixed rack internal teeth 12.
The window opening and closing self-locking mechanism consists of a handle mounting bolt 4, a fixed rack 5 at the upper part of the inner side of the movable window, a fixed rack 6 at the lower part of the inner side of the movable window, a push-pull rod 7, a push-pull handle 8, a handle mounting nut 9, a spring 10, a push-pull rod rack 11 and fixed rack inner teeth 12.
Wherein, the teeth of the inner teeth 12 of the fixed rack 5 at the upper part of the inner side of the movable window and the fixed rack 6 at the lower part of the inner side of the movable window incline towards the front side of the movable window 3, and the teeth of the push-pull rod rack 11 of the push-pull rod 7 incline towards the rear side of the movable window 3, as shown in fig. 2.
It should be noted that such a tooth-direction inclined design can save the pushing force when the movable window 3 is closed (slid forward), and increase the resistance when the movable window 3 is fixed at a certain position or when the movable window 3 is opened (slid backward). The spring 10 provides a pressure between the push-pull rod rack 11 and the internal teeth 12 of the fixed rack.
