[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-7The utility model provides a technical solution: an automatic positioning stern wheel support frame of a speedboat, comprising a fixing plate 3 fixedly connected to the stern 2 of a speedboat 1, wherein two fixing plates 3 are symmetrically arranged on the stern 2. Two parallel clamps 8 are vertically fixedly connected to the fixing plate 3, and limit slots 801 are provided at the upper and lower ends of the clamps 8. A support rod 4 is installed between the two clamps 8, and one end of the support rod 4 is rotatably connected to the clamps 8 through a rotating shaft 10, and the other end of the support rod 4 is rotatably connected to a moving wheel 5, and the support rod 4 is hollow inside and a fixing rod 11 is arranged inside the support rod 4, and one end of a tension spring 12 is fixedly connected to the fixing rod 11, and the other end of the tension spring 12 is fixedly connected to a positioning assembly that fixes the support rod 4 to the clamps 8. By installing the moving wheel 5 on the stern 2 of the speedboat 1 through the fixing plate 3, the speedboat 1 can be easily dragged on land, thereby increasing the mobility of the speedboat 1. The positioning assembly is provided to facilitate fixing the position of the moving wheel 5 , thereby increasing the stability when the speedboat 1 is towed.

[0029] like Figure 3 , Figure 4 As shown, the positioning assembly includes a slide groove 603 symmetrically arranged on the side wall of the support rod 4, and a sliding stop bolt 601 fixedly connected to the lower end of the tension spring 12. The slide groove 603 is arranged along the length direction of the support rod 4, and both ends of the sliding stop bolt 601 pass through the slide groove 603 and are threadedly connected with a locking nut 602. When the assault boat 1 needs to be dragged, the support rod 4 is rotated to the lower end of the stern plate 2. At this time, the sliding stop bolt 601 is clamped in the stop groove 801 at the lower end of the clamp plate 8, and the support rod 4 is relatively fixed to the clamp plate 8. When the moving wheel 5 needs to be folded up, the user pulls the locking nut 602 downward to pull the support rod 4 out of the stop groove 801, and then the support rod 4 can be rotated to fold upward, and the sliding stop bolt 601 is fixed in the stop groove 801 at the upper end.

When it is necessary to rotate the support rod, press the button 703, compress the reset spring 705 to make the movable rod 701 extend into the limiting tube 702, rotate the support rod 4 upward, and move the column 706 along the path of the movable groove 707. Compared with the structure of the first embodiment, the cooperation between the positioning assembly and the limiting groove 801 is more stable in the second embodiment, which prevents the positioning assembly from detaching from the limiting groove 801 when the speedboat 1 is dragged, and solves the problem of the support rod 4 detaching from the splint 8 when the speedboat 1 is overloaded.

[0031] The limiting ring 704 is fixedly connected to the limiting cylinder 702, and the limiting ring 704 is in contact with the inner wall of the support rod 4 and has an outer diameter greater than the inner diameter of the positioning hole 708. The limiting ring 704 is provided to prevent the limiting cylinder 702 from escaping from the positioning hole 708.

[0032] The fixing plate 3 and the clamping plate 8 are fixedly connected with a support rib 9 at the angle position. The support rib 9 increases the connection strength between the fixing plate 3 and the clamping plate 8 and increases the firmness of the device.

[0033] The rotating shaft 10 is arranged at the middle position of the clamping plate 8, and the supporting rod 4 can rotate around the rotating shaft 10 to the upper end and the lower end of the clamping plate 8, and the supporting rod 4 is fixed to the clamping plate 8 by cooperating with the limiting groove 801 through the positioning assembly.

[0034] The mobile device makes it easy for the speedboat 1 to move on land, and the moving wheels 5 can be freely retracted and extended, thereby reducing the resistance of the speedboat 1 running in water and solving the problem of insufficient practicality.
