Description

Technical Field

[0001] The utility model relates to a rotation limiting thrust-stopping structure for the warping of an electric outboard motor. Background Art

[0002] An outboard motor, as the name implies, refers to a propulsion engine installed on the outside of the hull (side), usually suspended on the outside of the transom, also known as an outboard motor. During use, the outboard motor's manual tilting device needs to be used to manually adjust the outboard motor's tilting angle and adjust the propeller's water entry angle. However, in the prior art, the traditional outboard motor's tilting limit shaft is limited by a rotating shaft plus two thrust blocks, and the thrust block plane is limited by contact with the rotating bracket plane. The parts are complex and the installation process is cumbersome, which greatly affects the production efficiency. Therefore, it is necessary to improve it.

[0003] The traditional limit shaft does not limit its rotational freedom, and there may be a certain degree of shaking during the ship's movement; but if the rotational freedom of the limit shaft is completely restricted, the matching plane of the limit shaft and the rotating bracket may not be completely in line with each other, resulting in line contact, which affects the assembly strength. Therefore, it is necessary to improve it.

[0004] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a new structure of the electric outboard motor tilting rotation limit shaft to make it more valuable for industrial use. Utility Model Content

[0005] In order to solve the above technical problems, the purpose of the utility model is to provide a rotation limit shaft for the tilting of an electric outboard motor.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A rotating limit shaft for lifting and lowering an electric outboard motor comprises a bracket, wherein a lower side of one side of the bracket is rotatably connected to a rotating bracket via a rotating shaft, and a lifting and lowering limit shaft for contacting and limiting the rotating bracket is connected to an upper side of the other side of the bracket, wherein the lifting and lowering limit shaft comprises a lifting and lowering limit shaft body, wherein the lifting and lowering limit shaft body is a lifting and lowering limit shaft body of a square structure, wherein a left connecting column and a right connecting column which are penetrated through the bracket are respectively connected to the left and right sides of the lifting and lowering limit shaft body, wherein the left connecting column and the right connecting column are both cylindrical structures, wherein the diameter of the left connecting column is greater than that of the right connecting column, a retaining ring is mounted on the right connecting column, and a limiting protrusion which protrudes from the inner wall of the bracket is connected to the left connecting column, and a limiting groove which matches the limiting protrusion is provided on the outer wall of the rotating bracket.

[0008] Preferably, in the electric outboard motor tilting rotation limit shaft, the tilting limit shaft body is integrally formed with the left connecting column and the right connecting column.

[0009] Preferably, in the electric outboard motor tilting rotation limit shaft, the right connecting column is provided with a mounting groove for connecting a retaining ring.

[0010] Preferably, in the electric outboard motor tilting rotation limit shaft, a blocking plate is connected to the outer side of the left connecting column.

[0011] Preferably, in the electric outboard motor tilting rotation limit shaft, an adjustable gap of 4° to 5° is provided between the limit groove and the limit protrusion 37 .

[0012] By means of the above solution, the utility model has at least the following advantages:

[0013] The cooperation of the limiting protrusion and the limiting groove of the utility model can make the lifting limiting shaft and the rotating bracket always keep completely fitting, ensuring the verticality of the horizontal plane of the outboard motor.
