Preferably, the connecting block is cuboid, and the thickness of the connecting block is smaller than or equal to the height of a gap between the rudder horn and the rudder blade.
Preferably, the projection shape of the insertion hole is a rectangle.
Preferably, the height of the inclined iron is greater than the height of a gap between the rudder horn and the rudder blade.
Preferably, the wedge is in a right-angled trapezoid shape.
Compared with the prior art, the utility model discloses an advantage is with positive effect: the utility model provides a semi-suspension rudder fixing structure, which comprises a rudder horn and a rudder blade, wherein a connecting block is inserted between the gap between the rudder horn and the rudder blade; two ends of the connecting block respectively extend out of gaps between the rudder horn and the rudder blade and are respectively provided with an insertion hole; and inclined irons are respectively inserted into the two jacks, the inclined irons are tightly attached to the surfaces of the rudder horn and the rudder blade, and the inclined irons are welded with the rudder blade. The utility model discloses a half-hanging rudder fixed knot constructs firmly reliably, can realize the encapsulation of rudder blade safely, high-efficient, conveniently, has guaranteed rudder system installation accuracy. The upper part and the lower part of the wedge are respectively and tightly attached to the surface of the rudder horn and the surface of the rudder blade, so that the rudder blade can be sealed; and the wedge is welded with the rudder blade, so that a secondary reinforcing effect can be achieved, and the stability and the reliability of the sealing of the rudder blade are ensured.
Other features and advantages of the present invention will become more apparent from the following detailed description of the invention when read in conjunction with the accompanying drawings.

Detailed Description
The following detailed description of the embodiments of the present invention is provided to illustrate and explain the present invention, and it should be understood that the embodiments described herein are only for the purpose of illustration and explanation, and are not intended to limit the present invention.
It should be noted that in the description of the present invention, the terms of direction or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. are based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 to 4, the semi-suspension rudder fixing structure of the present embodiment includes a rudder horn 10 and a rudder blade 20, and a connecting block 30 is inserted between a gap between the rudder horn 10 and the rudder blade 20; two ends of the connecting block 30 respectively extend out of gaps for hanging the rudder arms 10 and the rudder blades 20 and are respectively provided with an inserting hole 31; the two jacks 31 are respectively inserted with an inclined iron 40, the inclined iron 40 is respectively tightly attached to the surface of the rudder horn 10 and the surface of the rudder blade 20, and the inclined iron 40 is welded with the rudder blade 20.
The semi-suspension rudder fixing structure of the embodiment is stable and reliable, can safely, efficiently and conveniently realize the sealing of the rudder blade 20, and ensures the installation precision of the rudder system. The upper part and the lower part of the inclined iron 40 are respectively and tightly attached to the surface of the rudder horn 10 and the surface of the rudder blade 20, so that the rudder blade 20 can be sealed; and the wedge 40 is welded with the rudder blade 20, so that a secondary reinforcing effect can be achieved, and the stability and the reliability of the sealing of the rudder blade 20 are ensured.
