DETAILED DESCRIPTION

[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0020] like Figure 1-4 The electric lifting device for an outboard motor shown in the figure comprises an outboard motor bracket 4, wherein two symmetrical wing edges of the outboard motor bracket 4 are both provided with a plurality of corresponding jacks 12, at least three jacks 12 are provided on the two wing edges and are arranged equidistantly and obliquely, an angle fine-tuning rod 5 is provided between the two wing edges of the outboard motor bracket 4, and the side surface of the oil cylinder fixing frame 2 is in contact with the surface of the angle fine-tuning rod 5. When the angle fine-tuning rod 5 is inserted at different inclination angles, the distance between the outboard motor bracket 4 and the oil cylinder fixing frame 2 is adjusted, and then the angle of the outboard motor bracket 4 is adjusted for a second time according to the actual installation situation, which facilitates the operation of the staff. A screw hole is provided on the side of the outboard motor bracket 4, and a bracket fixing screw 3 is connected to the internal thread of the screw hole. The setting of the fixing screw 3 requires only turning the fixing screw 3 when connecting the outboard motor bracket 4 to the hull, and one end of the fixing screw 3 is against the hull, which is used to connect and fix the outboard motor bracket 4 to the hull.

[0021] The surface of the outboard motor bracket 4 is movably connected with the cylinder fixing frame 2, and a fourth screw rod 16 is penetrated through the top of the outboard motor bracket 4. One end of the fourth screw rod 16 is inserted into the cylinder of the cylinder fixing frame 2, so that the inner wall of the cylinder fixing frame 2 rotates along the surface of the fourth screw rod 16, and both ends of the fourth screw rod 16 are threadedly connected with fourth locking nuts 13, and the side surfaces of the two fourth locking nuts 13 are in contact with the side surfaces of the outboard motor bracket 4. In order to facilitate the rotation of the angle of the outboard motor bracket 4, after the outboard motor bracket 4 is subjected to force, the outboard motor bracket 4 rotates on the fourth screw rod 16 or rotates in the cylinder of the cylinder fixing frame 2 through the fourth screw rod 16, thereby facilitating the adjustment of the angle of the outboard motor bracket 4 after the force is applied. The provision of the two fourth locking nuts 13 is used to improve the stability of the connection between the outboard motor bracket 4 and the cylinder fixing frame 2.

[0022] An angle tilting bracket 6 is movably connected to the side of the cylinder fixing frame 2. A second screw rod 14 is provided between the two side plates of the cylinder fixing frame 2. The two ends of the two second screw rods 14 are respectively threadedly connected with second locking nuts 10. The sides of the two second locking nuts 10 are in contact with the surfaces of the two side plates of the cylinder fixing frame 2. The angle tilting bracket 6 is sleeved on the surface of the second screw rod 14, so that the angle tilting bracket 6 rotates along the surface of the second screw rod 14. After the angle tilting bracket 6 is subjected to force, it makes an arc motion, thereby pushing the second screw rod 14, and at the same time drives the angle tilting bracket 6 to make an arc motion on the surface of the second screw rod 14, thereby facilitating the movable connection between the angle tilting bracket 6 and the cylinder fixing frame 2, and the second locking nut 10 improves the stability of the connection between the angle tilting bracket 6 and the cylinder fixing frame 2.

[0023] The top of the angle tilt bracket 6 is movably connected with the electric cylinder 1, and one end of the electric cylinder 1 is movably connected to the cylinder fixing frame 2. A first screw rod 17 is penetrated through the top of the angle tilt bracket 6, and the electric cylinder 1 is sleeved on the surface of the first screw rod 17, so that the electric cylinder 1 rotates along the surface of the first screw rod 17, and both ends of the first screw rod 17 are threadedly connected with first locking nuts 9, and the sides of the two first locking nuts 9 are in contact with the sides of the angle tilt bracket 6. The cylinder fixing frame 2 is stepped, and a third screw rod 15 is penetrated through the top of the cylinder fixing frame 2, and one end of the electric cylinder 1 is sleeved on the surface of the third screw rod 15, so that the electric cylinder 1 rotates along the surface of the third screw rod 15, and both ends of the third screw rod 15 are threadedly connected with third locking nuts 11, and the two ends of the third screw rod 15 are threadedly connected with third locking nuts 11. The sides of the third locking nuts 11 are in contact with the sides of the cylinder fixing frame 2. When the electric cylinder 1 is working, in order to facilitate the rotation adjustment of the position of the outboard motor bracket 4, when the electric cylinder 1 is working, a force is applied to the angle tilt bracket 6 to drive it to rotate on the first screw rod 17, and the electric cylinder 1 is adjusted in angle as the angle tilt bracket 6 rotates. Therefore, the electric cylinder 1 rotates on the third screw rod 15 to facilitate the operation of the electric cylinder 1. The third locking nut 11 and the first locking nut 9 are respectively used for the stability of the connection between the electric cylinder 1 and the cylinder fixing frame 2, and the electric cylinder 1 and the angle tilt bracket 6.

[0024] A sleeve 8 is welded to the side of the angle tilt bracket 6 , and a fixed shaft 7 is connected to the inner thread of the sleeve 8 . The fixed shaft 7 is used to connect the outboard motor to the angle tilt bracket 6 .

[0025] Working principle: when adjusting the angle of the propeller, it is only necessary to connect the electric cylinder 1 to the external power supply through the wire and the electric cylinder switch, and it can be started by controlling the electric cylinder switch to be energized. The electric cylinder 1 works after being energized, and as the electric cylinder 1 contracts or extends, it is used to drive the movement of the angle tilt bracket 6, and the angle tilt bracket 6 drives the movement of the cylinder fixing bracket 2, and the cylinder fixing bracket 2 drives the adjustment of the angle of the outboard motor bracket 4 to change the angle of the propeller.
