[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figures 2-4This utility model provides an embodiment of a self-locking structure for adjusting the joints of a figurine skeleton, including a figurine upper body 1, a first joint 16, and a second joint 18. Mounting seats 2 are fixedly connected to the left and right sides of the bottom end of the upper body 1. Each mounting seat 2 has a movable frame 4 on its inner wall, and locking rods 5 are fixedly connected to the inner wall of the movable frame 4. The first connecting rods 8 on both sides have slots at opposite ends, and the locking rods 5 fit the slots to allow for the detachable replacement of the upper body 1 and legs. Multiple second springs 9 are fixedly connected to the top of the inner wall of the mounting seat 2, and the other ends of the second springs 9 are... A push plate 10 is fixedly connected, with the bottom end of the push plate 10 closely attached to the top end of the first connecting rod 8, so as to automatically push out after the leg is unlocked. Fixed sleeves 6 are fixedly connected to the front and rear sides of the opposite end of the inner wall of the mounting base 2. First springs 7 are fixedly connected to the opposite ends of the inner walls of the left and right fixed sleeves 6. The other ends of the first springs 7 are fixedly connected to the opposite ends of the movable frame 4. The outer walls of the movable frame 4 are slidably connected to the inner walls of the fixed sleeves 6. First buttons 3 are fixedly connected to the opposite ends of the left and right movable frames 4, so as to drive the movable frame 4 to move. The outer walls of the first buttons 3 are slidably connected to the inner walls of the left and right sides of the mounting base 2.

[0027] Specifically, users can change the legs of the figure according to their preferences. Pressing the first button 3 on the mounting base 2 causes the moving frame 4 to move, which in turn compresses the first spring 7. Simultaneously, the moving frame 4 moves the locking rod 5, causing it to disengage from the slot on the first connecting rod 8. At this point, the second spring 9 pushes the push plate 10, which automatically pushes the first connecting rod 8 out of the mounting base 2. Releasing the first button 3 causes the first spring 7 to spring the moving frame 4 back to its original position. Then, the user can install the figure's legs that need to be replaced, inserting the first connecting rod 8 into the mounting base 2. The front end of the first connecting rod 8 is curved, allowing for direct insertion. During insertion, the first connecting rod 8 compresses the second spring 9 and the first spring 7 via the locking rod 5 and the moving frame 4. When the locking rod 5 and the first connecting rod 8 are in the same position, the first spring 7 will move the locking rod 5 into the slot on the first connecting rod 8 via the moving frame 4, locking the first connecting rod 8 in place. Meanwhile, the second spring 9 remains compressed, waiting for the first button 3 to be pressed.

[0028] Reference Figure 1 , Figure 5 and Figure 6A second connecting rod 17 is fixedly connected to the bottom end of the first joint 16. A first gear 11 is fixedly connected to the left and right sides of the bottom ends of the first connecting rod 8 and the second connecting rod 17. A second gear 14 is meshed with the opposite end of the first gear 11. A second button 13 is fixedly connected to the opposite end of the second gear 14. The upper and lower second buttons 13 are slidably connected to the inner walls of the left and right ends of the first joint 16 and the second joint 18 to prevent the first joint 16 and the second joint 18 from rotating. A foot is fixedly connected to the bottom end of the second joint 18. A third spring 15 is provided on the inner wall of the first joint 16 and the second joint 18. The left and right ends of the third spring 15 are fixedly connected to the opposite end of the second gear 14. A rotating shaft 12 is fixedly connected to the left and right ends of the first gear 11. The outer wall of the rotating shaft 12 is fixedly connected to the inner walls of the left and right ends of the first joint 16 and the second joint 18. The second button 13 passes through the inner wall of the rotating shaft 12.

[0029] Specifically, the self-locking structures inside the first joint 16 and the second joint 18 are exactly the same. Therefore, only the internal structure of the first joint 16 is shown. When playing with the figure, the user needs to pose the figure's legs in different ways. Pressing the second button 13 on the first joint 16 or the second joint 18 causes the second gear 14 to move closer to the center and compress the third spring 15. The second gear 14 is no longer engaged with the first gear 11 for self-locking. Rotating the first joint 16 or the second joint 18 causes the first connecting rod 8 or the second connecting rod 17 to drive the rotating shaft 12 to rotate inside the first joint 16 or the second joint 18 through the first gear 11, allowing the legs to be posed in different positions. Then, releasing the second button 13 causes the third spring 15 to rebound and engage the second gear 14 with the first gear 11, locking the first joint 16 and the second joint 18 and keeping the figure in the pose posed by the user.

[0030] Working principle: When playing with the figure, users can replace the legs according to their preferences. Simply press the first button 3 on the mounting base 2, causing the moving frame 4 to move. The moving frame 4 compresses the first spring 7, and simultaneously moves the locking rod 5, causing it to disengage from the slot on the first connecting rod 8. At this time, the second spring 9 pushes the push plate 10, causing the push plate 10 to automatically push the first connecting rod 8 out of the mounting base 2. Release the first button 3, and the first spring 7 will spring the moving frame 4 back to its original position. Then, the user can install the figure leg that needs to be replaced, inserting the first connecting rod 8 into the mounting base 2. However, while playing with the figure, users may need to pose the figure's legs in different ways. At this time, simply press the second button 13 on the first joint 16 or the second joint 18. The second button 13 will drive the second gear 14 to move closer to the center and compress the third spring 15. The second gear 14 will no longer mesh with the first gear 11 and self-lock. Rotate the first joint 16 or the second joint 18 to pose in different ways. Then release the second button 13. The third spring 15 will rebound and mesh the second gear 14 with the first gear 11, so that the first joint 16 and the second joint 18 are self-locked, and the figure will maintain the rotated pose.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
