Detailed Description

The present invention provides a seaplane control surface suspension structure, which can be used for controlling the sea plane.

FIG. 1 is a schematic structural view of a door latch travel sensitivity enhancing mechanism according to the present invention when the door is opened; FIG. 2 is a schematic structural view of a door latch travel sensitivity enhancing mechanism according to the present invention when the door is closed; referring to fig. 1 and 2, the present invention provides a bolt stroke sensitivity enhancing mechanism on a hatch frame, including: the device comprises a shaft 1, a rocker arm 2, a support 3, a spring 4, a bushing 5, a standard component and a sensor; wherein the content of the first and second substances,

the shaft 1, the rocker arm 2, the spring 4, the bushing 5, the standard part and the sensor are integrated on the support 3, the spring 4 is always in a compression state, the rocker arm 2 is in an opening trend, and the purposes of light weight and simple assembly are achieved.

Illustratively, the shaft 1 is assembled in two coaxial holes of the support 3, two ends of the shaft 1 are positioned outside the holes of the support 3, one end of the shaft 1 is a cylinder, the other end of the shaft is a double-lug piece, a bolt assembly is assembled on the double lugs, and a bolt rod is in contact with a guide groove at one end of the rocker arm 2.

For example, the cylinder at one end of the shaft 1 may be designed to be non-cylindrical, so as to prevent the shaft 1 from rotating. Optionally, the two coaxial holes can be arranged to be non-coaxial, so that the effect of preventing the shaft 1 from rotating is achieved.

The design of 2 one end of rocking arm has the guide way, and the centre is close to the guide way direction design and has a through-hole, and the design of the other end has the target pilot hole, and rocking arm 2 is fixed on support 3 through the bolt assembly who passes the through-hole.

The spring 4 is assembled on the shaft 1 and is positioned between two coaxial holes of the support 3, one end of the spring 4 is in contact with the support 3, and the other end of the spring 4 is in contact with the bushing 5, so that the possibility of mistakenly closing the rocker arm 2 is avoided.

The bush 5 is fixed on the shaft 1 through a bolt and is positioned between two coaxial holes of the support 3.

The actual working process of the cabin door latch mechanism of the invention is as follows:

when the door of the cabin is closed, the bolt pushes the shaft 1 to move in the axial direction, and simultaneously the shaft 1 drives the rocker arm 2 to rotate through the guide groove until the target on the rocker arm 2 reaches the sensor sensing area on the support 3.

On the contrary, when the cabin door is opened, the bolt moves towards the direction of the principle shaft 1, the shaft 1 moves towards the bolt direction under the elastic force of the spring 4, and meanwhile, the shaft 1 drives the rocker arm 2 to rotate through the guide groove until the bushing 5 is contacted with the support 3. Therefore, the sensitivity of the bolt stroke is improved, and the mechanism is simple and reliable, light in total weight and high in reliability.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention.
