Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The structure of the blocking structure for the drain hole of the flywheel housing of the engine in the prior art is complex, tools such as a wrench are needed in the installation and disassembly processes, and the operation is complex.

In view of the above, the utility model provides the blocking structure for the drain hole of the flywheel housing of the engine, which has a simpler structure and is more convenient to operate.

As shown in fig. 2 and 3, the engine flywheel housing water drain hole blocking structure of the present invention comprises an engine housing 1 and a plug 2, wherein:

the bottom of the aircraft shell 1 is provided with a drain hole 11, and the inner wall of the drain hole 11 is provided with an annular groove.

The plug 2 comprises a base body 21 and a plug body 22 connected to the base body 21, the plug body 22 is matched with the drainage hole 11, and an annular bulge 221 matched with the annular groove is formed on the plug body 22.

When the water drain hole 11 needs to be sealed, the plug body 22 for sealing the plug 2 is only required to be sealed in the water drain hole 11. After plugging is completed, the seat body 21 of the plug 2 abuts against the bottom of the aircraft casing 1, and the annular convex part 221 on the plug body 22 of the plug 2 is embedded into the annular groove of the drain hole 11. Thus, the connection stability and the sealing performance of the plug 2 and the drain hole 11 are remarkably improved.

Optionally, the end of the plug body 22 is provided with a chamfered guide 222. By the guidance of the chamfered guide portion 222, the plug body 22 can enter the drain hole 11 more easily to close the drain hole 11.

Optionally, the plug 2 is made of elastic rubber, so that the plug 2 can be tensioned in the drain hole 11 with a certain pretightening force, and the connection strength between the plug 2 and the drain hole 11 is further improved.

As shown in fig. 2, after the plug 2 is plugged to the drain hole 11, since the connection strength between the plug body 22 and the drain hole 11 is high, it is difficult to remove the plug 2 from the drain hole 11 by pulling the holder body 21. In addition, during the process of drawing the seat body 21, the joint of the seat body 21 and the plug body 22 is easily damaged, thereby shortening the service life of the plug 2.

In order to solve the above problem, optionally, as shown in fig. 4, a pulling mechanism 3 is further provided on the plug 2, and the plug 2 can be easily removed from the drainage hole 11 by the pulling mechanism 3.

Optionally, as shown in fig. 4, the pulling mechanism 3 includes a pulling plate 31, a pulling rod 32, and a pulling grip 33, wherein: the traction plate 31 is attached to the upper end face of the plug body 22, the traction rod 32 penetrates through the plug 2, the first end of the traction rod 32 is connected to the traction plate 31, and the second end of the traction rod 32 penetrates through the seat body 21 of the plug 2 downwards. A pulling grip 33 is attached to a second end of the pulling bar 33.

The plug 2 can be easily pulled out of the drain hole 11 by pulling the pulling grip 33 downward.

During the drawing process, the drawing plate 31 presses the plug body 22 downwards uniformly under the drawing of the drawing rod 32, so that the plug body 22 blocking the plug 2 is extruded out of the water drainage hole 11. In the process, the plug 2 is not at risk of being pulled.

Optionally, the drawplate 31 is a corrosion-resistant stainless steel plate.

The present invention is not intended to be limited to the particular embodiments shown, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
