Detailed Description

In order to make the technical solutions of the present invention clearer and clearer for those skilled in the art, the present invention will be described in further detail with reference to the following embodiments and drawings, but the embodiments of the present invention are not limited thereto.

As shown in fig. 1-3, this embodiment provides a sealing structure for an actuator cylinder of a flight simulator, which includes a cylinder 1, a sealing ring 2 is fixed at one end of the inner side of the cylinder 1, a piston 3 is slidably mounted inside the cylinder 1, a push rod 4 is fixed on the piston 3, the push rod 4 penetrates through the piston 3, oil holes 5 are provided at two ends of one side of the cylinder 1, a rectangular mounting groove 6 is provided at an intermediate position outside the piston 3, a first rubber gasket 7 is provided inside the rectangular mounting groove 6, tapered mounting grooves 8 are provided at two ends outside the piston 3, a second rubber gasket 9 is provided inside the tapered mounting groove 8, through pipes 10 are provided at two sides of the piston 3, and the through pipes 10 at two sides of the piston 3 are respectively communicated with the tapered mounting groove 8.

In this embodiment, as shown in fig. 3, the empty groove 11 has been seted up to the outside of sealing washer 2, and sealing washer 2 inboard is provided with inclined plane 12, and inclined plane 12 inclines towards the inboard of barrel 1, and when barrel 1 internal pressure increased, extrudeed the inclined plane 12 of sealing washer 2, because the existence of empty groove 11, sealing washer 2 takes place to deform and more laminates between barrel 1 push rod 4, increases sealed effect.

In the embodiment, as shown in fig. 2, two sets of through pipes 10 are disposed on both sides of the piston 3, and the ends of the through pipes 10 are tapered to accelerate the injection of the hydraulic oil.
