Description

Technical Field

[0001] This utility model relates to the field of doll technology, and in particular to a connecting part and base plate for a doll's leg skeleton. Background Technology

[0002] As the core structure of a movable doll, the doll's skeleton directly affects its expressiveness and scene adaptability.

[0003] Traditional doll skeletons typically employ two types of technical solutions:

[0004] 1. Universal joint structure (e.g., CN205516450U): Multi-angle adjustment is achieved through the universal joint (93) and the grip plate (91) in conjunction with the sleeve (94). Although this solves the problems of joint flexibility and anti-drop, it has the following drawbacks:

[0005] 1) Fixed and monotonous leg posture: Universal joints (such as 90F, 90G) rely on real-time adjustment to maintain posture and cannot provide a static fixation function with preset bending angle, resulting in additional support required for kneeling, cross-legged and other postures;

[0006] 2) No extended support system: The foot (13) is only an independent moving part, which is prone to falling over on slopes and soft surfaces and lacks scene adaptability.

[0007] 2. Modular joint structure (e.g., CN221618573U): The components are replaceable through the rotating part (5) and the joint part (19), but the leg design still has limitations:

[0008] 1) Homogeneous joint function: The foot joints (9, 10, 12) only provide basic rotation function and cannot achieve differentiated curvature (such as 90° kneeling posture and 45° cross-legged posture, which require customized skeleton);

[0009] 2) Support depends on the appearance: Stability is passively provided by the doll's appearance, and there is no autonomous stabilization mechanism when the appearance is removed or in complex scenes. Utility Model Content

[0010] The technical problem to be solved by this utility model is to provide a connector and base plate for the leg skeleton of a doll. Through the multi-curvature design of the knee connector and the multi-locking system of the base plate, the leg posture can be flexibly adjusted, the joints can be replaced, and the overall stability can be improved.

[0011] To solve the above-mentioned technical problems, this utility model discloses a connector and base plate for a doll's leg skeleton. The connector includes two knee connectors and two foot connectors. The bottom surface of the base plate touches the ground, and multiple snap-fit ​​positions are provided on its surface. The bottom of each foot connector is snapped and fixed to any snap-fit ​​position on the base plate.

[0012] The left and right leg skeletons of the doll are each composed of at least two straight skeletons connected by at least one knee connector, wherein the bottom of the lowest straight skeleton is connected to the foot connector.

[0013] The knee connector has at least two shapes.

[0014] As an optional implementation, the foot connector includes a base and a connecting tube; the surface of the base is provided with a groove; one end of the connecting tube is connected to a straight frame with an angle, and the other end of the connecting tube is inserted vertically into the groove of the base.

[0015] As another alternative implementation, the straight frame is made of iron pipe or plastic pipe.

[0016] As another optional implementation, the straight frame is a round tube or a square tube.

[0017] As another alternative implementation, the knee connector is arc-shaped, and the arc has at least two different curvatures.

[0018] As another alternative implementation, a plurality of stabilizing members are evenly hinged at the bottom edge of the base plate. When opened, the stabilizing members extend outward from the base plate and abut against and support the base plate.

[0019] As another alternative implementation, the stabilizer can be recessed into the bottom groove of the base plate.

[0020] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0021] 1. Modular design: The separate structure of the knee and foot connectors supports flexible assembly, allowing users to freely combine them according to the size and posture requirements of the doll, thus improving versatility.

[0022] 2. Multiple pose support: The knee connector has multiple shapes (at least two) to simulate different bending angles (such as standing, kneeling or running), enhancing the realism and playability of the doll's movements.

[0023] 3. Improved stability: The snap-fit ​​design of the base plate allows the foot connectors to be fixed in different positions, adapting to uneven ground and preventing the doll from tipping over.

[0024] 4. Modular components simplify the production process, reduce mold costs, and are suitable for mass production. Attached Figure Description

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] See Figures 1-6 This utility model discloses a connector and base plate for a doll's leg skeleton. The connector includes two knee connectors 1 and two foot connectors 2. The bottom surface of the base plate 3 touches the ground, and multiple snap-fit ​​positions 31 are provided on its surface. The bottom of each foot connector 2 is snap-fitted and fixed to any snap-fit ​​position 31 of the base plate 3.

[0034] The left and right leg skeletons of the doll are both formed by at least two straight skeletons 4 connected by at least one knee connector 1, wherein the bottom of the lowest straight skeleton 4 is connected to the foot connector 2.

[0035] The knee connector 1 has at least two shapes.

[0036] This embodiment of the utility model employs a stabilization system consisting of a replaceable curvature knee connector 1 and a snap-fit ​​base plate 3, which has the following beneficial effects:

[0037] 1. Modular design: The separate structure of the knee connector 1 and foot connector 2 supports flexible assembly, allowing users to freely combine them according to the size and posture requirements of the doll, thus improving versatility.

[0038] 2. Multiple posture support: The knee connector 1 has multiple shapes (at least two) to simulate different bending angles (such as standing, kneeling or running), enhancing the realism and playability of the doll's movements.

[0039] 3. Improved stability: The snap-fit ​​design of the base plate 3 allows the foot connector 2 to be fixed in different positions, adapting to uneven ground and preventing the doll from tipping over.

[0040] 4. Modular components simplify the production process, reduce mold costs, and are suitable for mass production.

[0041] Optionally, the connectors can have standardized interfaces (such as uniform buckle sizes) to facilitate compatibility with third-party doll skeletons and expand the range of applications.

[0042] In an optional embodiment, the foot connector 2 includes a base 21 and a connecting tube 22; the surface of the base 21 is provided with a groove; one end of the connecting tube 22 is connected to a straight frame 4 with an angle, and the other end of the connecting tube 22 is inserted vertically into the groove 211 of the base 21.

[0043] When the straight frame 4 is vertical, the foot connector 2 may only include the base 21 and does not require the connecting tube 22.

[0044] Quick assembly and disassembly: The design of the connecting tube 22 directly inserting into the groove of the base 21 simplifies the assembly process, which can be completed without tools, improving the user experience. Adjustable angle: The fixed angle (such as 90° or 45°) between the connecting tube 22 and the straight frame 4 supports customized foot postures, enhancing the stability of the doll standing.

[0045] In this embodiment, the base 21 groove cannot be rotated after being inserted into the connecting tube 22, and the base 21 groove is provided with an anti-dislodgement structure (such as a snap-on slot).

[0046] The snap-fit ​​slots provide a "one-click locking" mechanism to ensure that the foot connector 2 does not fall off when the doll is moved or played with, improving safety. The non-rotatable structure prevents accidental shifts in posture and maintains the stability of the doll's pose.

[0047] Optionally, a silicone pad layer can be added to the inner wall of the groove 211 to increase the coefficient of friction and prevent the connecting tube 22 from loosening under stress.

[0048] Optionally, the end of the connecting tube 22 is provided with a threaded hole to support expansion accessories (such as pulleys or magnetic bases).

[0049] In yet another alternative embodiment, the straight frame 4 is made of iron pipe or plastic pipe.

[0050] Optionally, iron pipes can be electroplated with an anti-rust coating, and plastic pipes can be treated with UV stabilizers to prevent aging.

[0051] Optionally, different colors or textures can be used to distinguish materials (such as blue plastic pipes and silver iron pipes) for easy user identification.

[0052] In yet another alternative embodiment, the straight frame 4 is a round tube or a square tube.

[0053] In yet another optional embodiment, the knee connector 1 is arc-shaped, and the arc has at least two curvatures. For example:

[0054] Posture type Left leg curvature Right leg curvature Running posture 105° (back kick) 80° (forward leg swing) Walking posture 65° (support leg) 45° (swinging leg) upright posture 8° (slightly bent weight-bearing leg) 5° (Balance Leg)

[0055] Optionally, the knee connector 1 uses a magnetic interface to allow users to switch curvature on-site.

[0056] Optionally, curvature values ​​can be imprinted on the surface (e.g., "S" for small curvature, "L" for large curvature) to simplify the selection process.

[0057] In another optional embodiment, a plurality of stabilizing members 5 are evenly hinged at the bottom edge of the base plate 3. When opened, the stabilizing members 5 extend outward from the base plate 3 and abut against and support the base plate 3. After unfolding, the stabilizing members 5 abut against the ground, adapting to uneven surfaces such as carpets and slopes, and preventing the doll from tipping over; the hinged design allows for folding and storage, reducing storage space.

[0058] Optionally, a rubber suction cup can be embedded at the end of the stabilizer 5 to enhance grip.

[0059] In another alternative embodiment, the stabilizer 5 may be retracted into the bottom groove 32 of the base plate 3.
