Description

Technical Field

[0001] This utility model relates to the field of doll skeleton technology, and more specifically, to a doll skeleton. Background Technology

[0002] Doll skeletons often employ biomimetic human skeletal structures to simulate the real human form, thereby increasing the fun for children during play. Various human postures can be simulated by rotating different joints. For example, the movable joint structure of a doll or puppet (application number CN92114328.1), while allowing its components or connections to be stable and positioned arbitrarily, has a single structural member corresponding to the human sternum. This prevents the waist from bending over properly when simulating a human bending motion, resulting in an overly stiff posture. Therefore, this paper proposes a new doll skeleton to address these issues. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a doll skeleton to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a doll skeleton, including a torso, arms and lower limbs, wherein the top two sides of the torso are symmetrically connected to arms via arm connectors, and the bottom two sides are rotatably connected to lower limbs via lower limb connectors.

[0005] Preferably, the bottom side of the arm connector has a mounting hole for installing a connecting post. One end of the connecting post is pivotally connected to the arm connector, while the other end is pivotally connected to the top of the abdominal cavity.

[0006] Preferably, the lower limb connector is provided with three sets of spherical connecting posts, with the spherical connecting posts on the left and right sides respectively embedded in the ball sockets of the femoral connector.

[0007] Preferably, the arm connector has socket joints on both the left and right sides, and scapulae are pivotally connected in both socket joints. The other end of the scapulae is connected to the humerus by a connecting cylinder to form a rotating structure. The end of the humerus away from the scapula is embedded in the rotating groove of the forearm. The forearm and elbow joint are also connected by a connecting cylinder to form a rotating structure.

[0008] Preferably, the femoral connector has a locking block at one end away from the torso that is rotatably connected to the locking groove of the femur, and the other end of the femur is connected to the patella by a connecting cylinder, and the end of the patella is provided with a knee joint connected to it by a connecting cylinder.

[0009] The technical effects and advantages of this utility model are as follows:

[0010] Compared with existing technologies, this doll skeleton can rotate its arms, lower limbs, and torso during use, simulating different human forms and increasing its realism.

[0011] Compared to existing technologies, this doll skeleton features a locking block at the end of the femoral connector furthest from the torso, which rotatably connects to the femur's locking groove. This allows the femoral connector to rotate relative to the femur, simulating the torsional effect of the lower limb. Utilizing the connecting cylinder's connection characteristics, the knee joint can perform knee flexion and other movements relative to the patella. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] Please see Figures 1-6 In this embodiment of the utility model, a doll skeleton includes a torso 1, arms 2 and lower limbs 3. The top two sides of the torso 1 are symmetrically connected to the arms 2 by arm connectors 11, and the bottom two sides are rotatably connected to the lower limbs 3 by lower limb connectors 14. When using the doll skeleton, its function of simulating human form can be utilized. By rotating the arms 2, lower limbs 3 and torso 1 respectively, different human forms can be simulated, increasing its realism.

[0025] The bottom side of the arm connector 11 has a mounting hole for mounting the connecting post 12. One end of the connecting post 12 is pivotally connected to the arm connector 11, while the other end is pivotally connected to the top of the abdominal cavity 13. The arm can be rotated using the connecting post 12 to simulate the movement of a real arm. The abdominal cavity 13 can also use the connecting post 12 to simulate the bending or turning movements of a real human body.

[0026] The lower limb connector 14 is provided with three sets of spherical connecting posts. The spherical connecting posts on the left and right sides are respectively embedded in the ball sockets of the femoral connector 31. The ball sockets of the femoral connector 31 rotate around the spherical connecting posts, which allows the lower limb 3 to rotate relative to the torso 1.

[0027] Both sides of the arm connector 11 are provided with socket joints, and scapulae 21 are pivotally connected within each set of socket joints. The other end of scapulae 21 is connected to humerus 22 by a connecting cylinder to form a rotating structure. Utilizing the connecting cylinder, scapulae 21 and humerus 22 can rotate relative to each other, and the end of humerus 22 away from scapulae 21 is embedded in the rotating groove of forearm 23. Forearm 23 and elbow joint 24 are also connected by a connecting cylinder to form a rotating structure. Similarly, utilizing the connecting cylinder, forearm 23 and elbow joint 24 can rotate, thereby simulating some human movement actions.

[0028] The end of the femoral connector 31 furthest from the torso 1 is provided with a locking block that is rotatably connected to the locking groove of the femur 32. This allows the femoral connector 31 and the femur 32 to rotate relative to each other, simulating the torsional effect of the lower limb. The other end of the femur 32 is connected to the patella 33 by a connecting cylinder. The end of the patella 33 is provided with a knee joint 34 connected to it by a connecting cylinder. Utilizing the connection characteristics of the connecting cylinder, the knee joint 34 can perform knee flexion and other movements around it relative to the patella 33.

[0029] The working process of this utility model is as follows: When using the doll skeleton, the arms 2, lower limbs 3 and torso 1 can be rotated to simulate different human body shapes. The arms can be rotated using the connecting column 12, and the abdominal cavity 13 can also be simulated by using the connecting column 12 to simulate the bending or turning movements of a real human body. By using the connecting column, the scapula 21 and humerus 22 can rotate relative to each other. Similarly, by using the connecting column, the forearm 23 and elbow joint 24 can rotate. By using the connecting characteristics of the connecting column, the knee joint 34 can perform knee bending and other movements around its relative to the patella 33.
