Description

Technical Field

[0001] This utility model relates to the field of articulated joint structures for movable parts of figurines, dolls, models, etc., and particularly to a novel mechanical waist structure for the body. Background Technology

[0002] Among the known movable joints in humanoid dolls, figures, and models, the waist and hip joints are not fully utilized. They are difficult to make complex movements when the legs are in motion, and their space utilization is still insufficient. Especially when performing tension movements such as high kicks and side kicks, the internal space of the hip joint interferes with the outer shell structure, compressing the range of motion of the legs. The fixed hip joint frame cannot be dynamically adjusted with the leg movements, resulting in most of the internal space being wasted due to mechanical interference during joint movement. It is difficult to present poses that require the coordination of the torso and lower limbs, such as squats and lunges, and the ideal state is not achieved. Therefore, a new body structure needs to be designed for the hip joint. Utility Model Content

[0003] The purpose of this invention is to provide a novel mechanical waist structure to solve the technical problems of the existing waist and hip structure being imperfect in use, making it difficult to perform complex movements during leg activities, and having insufficient space utilization.

[0004] To solve the above-mentioned technical problems, this utility model provides a novel mechanical waist structure, including: a spherical pull-down structure, a connecting plate movably connected to the spherical pull-down structure, and a connecting pile movably connected to the connecting plate. The spherical pull-down structure includes a hip connecting plate, a connecting track pile fixedly connected to the hip connecting plate, and a connecting ball spliced ​​to the connecting track pile.

[0005] Preferably, the hip connecting plate has a connecting ball recess A on each side for connecting the ball joint of the thigh, and the middle position of the hip connecting plate is fixedly connected to one end of the connecting track post.

[0006] Preferably, the end of the connecting track pile away from the hip connecting plate is provided with a fixed track groove, which is a strip-shaped through hole.

[0007] Preferably, the connecting ball is provided with a connecting track groove that can be movably sleeved with one end of the connecting track pile, and one end of the connecting track pile including the fixed track groove can be movably sleeved in the connecting track groove.

[0008] Preferably, the connecting ball is provided with a positioning groove corresponding to the position of the fixed track groove. The positioning groove is a circular through hole with a diameter smaller than that of the fixed track groove. The positioning groove and the fixed track groove are connected by a track positioning stake. The length of the track positioning stake matches the size of the connecting ball after it is inserted into the positioning groove.

[0009] Preferably, a positioning stake for fixing to the waist is fixed in the middle of the connecting plate, and connecting ball wall B and connecting ball wall A are fixedly connected to the upper and lower ends of the connecting plate, respectively.

[0010] Preferably, the connecting ball wall A is provided with a connecting ball recess B, which can movably fit the connecting ball; the connecting ball wall B is provided with a connecting ball recess C.

[0011] Preferably, the upper and lower ends of the connecting pile are respectively fixed with connecting ball head A and connecting ball head B, and the connecting ball head B can be movably sleeved on the connecting ball recess C.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention allows the joints of the puppet model's legs and hips to have a greater range of motion by performing a spherical downward pull motion. The movable joints save space while providing downward stretching space, which greatly increases the range of motion of the legs. Furthermore, due to the spherical movable joints, when the legs perform tension-filled movements such as high kicks and side kicks, the internal space of the hips will not interfere too much with the outer shell structure, resulting in natural movement performance without any noticeable flaws.

[0018] like Figures 1-6 As shown, this utility model provides a novel mechanical waist structure, including: a spherical pull-down structure, a connecting plate 5 movably connected to the spherical pull-down structure, and a connecting pile 8 movably connected to the connecting plate 5. The spherical pull-down structure includes a hip connecting plate 1, a connecting track pile 2 fixedly connected to the hip connecting plate 1, and a connecting ball 3 spliced ​​to the connecting track pile 2.

[0019] Furthermore, the hip connecting plate 1 is provided with a connecting ball recess A on each side for connecting the ball joint of the thigh, and the middle position of the hip connecting plate 1 is fixedly connected to one end of the connecting track post 2.

[0020] Furthermore, the end of the connecting track pile 2 away from the hip connecting plate 1 is provided with a fixed track groove 201, which is a strip-shaped through hole.

[0021] Furthermore, the connecting ball 3 is provided with a connecting track groove 301 that can be movably sleeved with one end of the connecting track pile 2, and one end of the connecting track pile 2, including the fixed track groove 201, can be movably sleeved in the connecting track groove 301.

[0022] Furthermore, the connecting ball 3 is provided with a positioning groove 302 corresponding to the position of the fixed track groove 201. The positioning groove 302 is a circular through hole, and the diameter of the positioning groove 302 is smaller than the diameter of the fixed track groove 201. The positioning groove 302 and the fixed track groove 201 are connected by a track positioning stake 4. The length of the track positioning stake 4 matches the size of the connecting ball 3 after it is inserted into the positioning groove 302.

[0023] Furthermore, a positioning stake 501 for fixing to the waist is fixedly provided in the middle of the connecting plate 5, and connecting ball wall B and connecting ball wall A are fixedly connected to the upper and lower ends of the connecting plate 5 respectively.

[0024] Furthermore, the connecting ball wall A is provided with a connecting ball recess B, which can movably fit the connecting ball 3; the connecting ball wall B is provided with a connecting ball recess C.

[0027] Working principle: When using the movable body mechanical waist structure of this utility model, the entire joint structure is first assembled. The hip connecting plate 1 can be limited by the track positioning pile 4. After the joint structure is assembled, in actual use, the hip connecting plate 1 moves downward in the connecting ball 3. The connecting ball B wraps around the connecting ball 3, and the connecting ball 3 drives the hip connecting plate 1 to make a spherical movement. By making a spherical downward movement, the joints of the puppet model such as the legs and hips have more range of motion. When performing tension actions such as high leg raises and side kicks, the internal space of the hip will not interfere too much with the outer shell structure.

[0028] Compared with the prior art, the beneficial effects of this utility model are: by making a spherical downward pull, the joints of the legs and hips of the puppet model have more range of motion. The movable joints save space while providing downward stretching space. This downward stretching space can greatly provide the range of motion of the legs. Moreover, because of the spherical movable joints, when the legs make tension movements such as high kicks and side kicks, the internal space of the hips will not interfere too much with the shell structure, and the movement performance is natural and will not be obvious.
