DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] As Figures 1-3 shown, the present utility model provides a lightweight steering knuckle assembly for a watercraft, which includes a fixed seat 1, a first connecting seat 2, a connecting arm 3, a second connecting seat 4, a connecting frame and a steering handle 5 that are connected in sequence. The connecting arm 3 is a hollow cylindrical structure and two are arranged side by side; the first connecting seat 2 includes a left cylindrical part 6 and a right cylindrical part 7 that are arranged side by side. Both the left cylindrical part 6 and the right cylindrical part 7 are hollow cylindrical structures and are fixed together at adjacent positions. A communicating slit 8 is provided at the fixed position of the left cylindrical part 6 and the right cylindrical part 7. Corresponding locking holes 9 are provided on the upper and lower walls of the slit 8. One ends of the two connecting arms 3 are respectively inserted into the left cylindrical part 6 and the right cylindrical part 7 and are locked through the locking holes 9. The second connecting seat 4 has the same structure as the first connecting seat 2 and is symmetric.
[0015] This structure is a split design and a lightweight design. The fixed seat 1, the first connecting seat 2, the connecting arm 3, the second connecting seat 4, the connecting frame and the steering handle 5 are connected in sequence. The connecting arm 3 adopts a hollow cylindrical structure, and two are installed side by side. On the premise of ensuring strength, it is lighter. The first connecting seat 2 and the second connecting seat 4 are connected and fixed to the connecting arm 3 by a sleeved locking method, which is convenient for installation. The adjacent outer walls of the left cylindrical part 6 and the right cylindrical part 7 are connected as a whole. The slit 8 is located between the hollow inner cavities of the left cylindrical part 6 and the right cylindrical part 7, so that the connecting part of the left cylindrical part 6 and the right cylindrical part 7 is divided into upper and lower parts. After the two connecting arms 3 are inserted into the left cylindrical part 6 and the right cylindrical part 7, bolts are inserted into the locking holes 9 and tightened. As the bolts are tightened, the slit 8 becomes smaller, so that the inner diameters of the left cylindrical part 6 and the right cylindrical part 7 become smaller, and the inserted ends of the connecting arms 3 are locked. The installation is convenient and the connection strength is high.
[0016] As Figure 3As shown, the barrel walls of the left barrel part 6 and the right barrel part 7 are of a hollow structure, further reducing the weight and making it more lightweight.
[0017] As Figure 3 shown, the fixed seat 1 includes a seat body 10, a positioning groove 11 provided on the seat body 10, and pin shaft holes 12 provided on the outer walls on both sides of the positioning groove 11. The upper end of the positioning groove 11 and the end facing away from the first connecting seat 2 are open.
[0018] The seat body 10 is used to connect the steering shaft of the watercraft. The positioning groove 11 facilitates the positioning of the shaft head of the steering shaft, and is limited by inserting a pin shaft into the pin shaft hole 12, which is convenient for installation. At the same time, the seat body 10 with a hollow structure is more lightweight.
[0019] As Figure 3 shown, the bottom of the positioning groove 11 on the seat body 10 is of a hollow structure, further reducing the weight and making it more lightweight.
[0020] As Figures 1-2 shown, the connecting frame includes an upper connecting plate 13, side connecting frames 14 and a lower connecting frame 15. One end of the upper connecting plate 13 is fixed to the upper side of the other end of the second connecting seat 4, and the other end is inclined upward and fixed to the steering handle 5. The side connecting plates are respectively fixed to both sides of the other end of the second connecting seat 4, and the other end is fixed to the middle of the upper connecting plate 13. The lower connecting frame 15 is fixed to the lower side of the other end of the second connecting seat 4, and the other end is fixed to the middle of the upper connecting plate 13.
[0021] The connection strength and support strength of the upper connecting plate 13 are further enhanced by the two side connecting frames 14 and the lower connecting frame 15, the structure is more stable, the force is more uniform, and the problem of easy body wall fracture during use is further avoided.
