Description

Technical Field

[0001] This utility model belongs to the field of model toy technology, specifically, it relates to a puppet joint and a puppet skeleton connected by the puppet joint. Background Technology

[0002] Doll models are typically assembled from multiple parts. To give the doll model some movement characteristics and enhance its playability, rotating joints are installed between the parts. Joints are very common structural components in doll models. For example, there are joints between the upper arm and forearm, and between the thigh and lower leg. This allows the upper arm and forearm to rotate relative to each other at a certain angle, and the thigh and lower leg to rotate relative to each other at a certain angle, giving players more enjoyment in handling them.

[0003] Moreover, joints can be used not only in human-like joints, but also between other parts to allow for rotational movement.

[0004] Currently, puppet joints typically involve two parts that are rotatably connected via a shaft and a hole. When assembling a puppet, the shaft and hole of each part must be inserted to achieve the rotational function. For example, in patent CN118925240A, for the first and second connecting parts to rotate, a shaft hole needs to be provided on the first connecting part, and a rotating shaft must pass through both parts before they can be assembled, thus enabling the first and second connecting parts to rotate.

[0005] However, the joints of these puppets are relatively small, making installation difficult even with tweezers, which hinders the smooth assembly and disassembly process. The cumbersome assembly and disassembly process, coupled with the possibility of the joints falling off or being lost after assembly, results in a less than ideal player experience. Therefore, it is necessary to improve the puppet joints to reduce the complexity of assembly and disassembly. Utility Model Content

[0006] This invention relates to a puppet joint and a puppet, which solves the problem of poor player experience caused by the assembly method of shaft and hole plug-in for puppet joints. By using plastic materials with different melting points and non-melting properties for the connecting frame and connecting post, the two components are integrally molded using secondary injection molding to form a non-removable puppet joint, thereby improving the connection strength of the puppet joint. It can be connected to the limbs by plugging in the connecting post, which allows for efficient and reliable assembly of the puppet and improves the player experience.

[0007] The technical solution adopted in this utility model is as follows:

[0008] On one hand, this application provides a puppet joint, including:

[0009] The connecting frame includes a pair of integral clamping plates and a pair of hinge shafts provided between the pair of clamping plates, with both ends of each hinge shaft being integrally connected to the pair of clamping plates;

[0010] A pair of connecting posts, with their opposite ends hinged to corresponding hinge axes, and their opposing ends used to mount the doll's limbs.

[0011] Optionally, the connecting frame and the connecting column are plastic components with different melting points and that do not melt into each other. The high melting point component is used to be installed on the fixed mold after injection molding. After the moving mold and the fixed mold are closed, the high melting point component, together with the moving mold and the fixed mold, forms the injection cavity of the low melting point component. At the same time as the low melting point component is injection molded, the connecting column is hinged to the hinge shaft.

[0012] Optionally, the shape of each clamping plate is formed by connecting two spaced circular plates on the same side with a straight line and connecting the other side with an arc that is recessed between the circular plates, thereby enclosing and forming the arc-shaped plate surface of the clamping plate.

[0018] Optionally, the end face of the plug-in block has a first recess, the molded part has a receiving hole, the receiving hole has a first protrusion, and a second recess is formed around the first protrusion in the receiving hole. The first protrusion is used to be inserted into the first recess for mating, and the second recess is used to mate with the outer periphery of the plug-in block.

[0019] Optionally, multiple pairs of connecting posts are arranged circumferentially on the annular flow channel in a manner parallel to the axis of the plug posts, forming the high melting point component integral with the annular flow channel after injection molding.

[0020] On the other hand, this application also provides a doll skeleton, including the doll joints described above, which are connected between the thigh and the lower leg, and between the upper arm and the forearm.

[0021] Optionally, the doll skeleton includes:

[0022] The three-way ball joint includes two ball joints connected in opposite directions, and a ball joint connected at the upper end between the two ball joints. The ball joint at the upper end of the three-way ball joint is used to connect with the lower ball joint of the waist and abdomen connecting sleeve. The two ball joints connected in opposite directions are respectively connected to a ball joint sleeve. The lower end of the ball joint sleeve is fixedly connected with a plug post for plugging into the upper end of the thigh.

[0023] The neck armor piece has ball heads at both the top and bottom. The ball head at the top of the neck armor piece is used to connect to the doll's head.

[0024] The cross connector is in the shape of a cross protruding in the front-back and left-right directions. Its upper end is connected to the ball head at the lower end of the neck armor-shaped piece, and its lower end is connected to the ball head at the upper end of the waist connecting sleeve. The cross connector has vertical connecting holes at both ends.

[0025] Shoulder connectors are rotatably mounted on the left and right ends of the cross connector by passing a steel shaft through the connecting hole and the shoulder connector;

[0026] The first shoulder frame is a hollow cylinder, and a ball head is fixedly connected to the hollow cylinder in the radial direction. The ball head of the first shoulder frame is connected to the outer side of the shoulder connector by a ball head connection.

[0027] The second shoulder skeleton is disposed on the outer periphery of the hollow cylinder of the first shoulder skeleton. The second shoulder skeleton includes a perforated plate and a ball head extending upward from the edge of the perforated plate. The ball head of the second shoulder skeleton is used to connect with the ball head of the doll's shoulder armor shaping piece. The holes of the hollow cylinder and the perforated plate are inserted into the doll's shoulder deltoid muscle shaping piece.

[0028] The upper arm and the deltoid muscle shaping piece of the doll's shoulder are integrated. The lower end of the forearm is connected to one end of the double ball head, and the other end of the double ball head is used to connect to the doll's hand ball head.

[0029] Optionally, the outer periphery of the thighs and calves also features multiple slots for inserting armor-shaped components.

[0030] Optionally, the lower end of the calf is connected to one end of the double ball head, and the other end of the double ball head is connected to the ball head of the doll's shoe.

[0031] Optionally, the front and rear ends of the cross connector are used to insert the mascot's breastplate and backplate model parts.

[0032] This utility model has the following beneficial effects:

[0033] (1) In this application, the connecting frame and the connecting column are made of plastic materials with different melting points and do not melt into each other. The connecting frame and the connecting column are integrally molded by secondary injection molding to form a non-removable puppet joint, thereby improving the connection strength of the puppet joint.

[0034] (2) This application transforms the relative rotational connection between limbs into the rotation of the limbs relative to the puppet joint, thereby forming a non-detachable puppet joint between the connecting column and the connecting frame. This structural design makes the joint versatile and applicable to various limbs and parts that require rotational connection, thus expanding the application range of the joint.

[0035] (3) This application can be connected to the limbs by plugging in the plug-in post, which eliminates the need for the installation of the pivot, and can assemble the doll efficiently and reliably, greatly improving the player's experience.

[0036] (4) Since the connection between the plug and the limb is a plug-in, the plug can also rotate in the plug hole after the connection is made, which allows the doll to have more movement characteristics and improves the player experience of the doll.

[0037] (5) This application can change and position the rotation angle of the limb by the cooperation of the arc-shaped protrusion of the hinge shaft with the groove of the connecting plate.

[0038] (6) This application allows for the insertion of various shaped parts through the connecting block on one side of the connecting frame. The shaped parts can also cover the joints of the doll, which not only improves the aesthetics of the doll but also prevents the doll from falling and hitting the joints, causing the joints to disintegrate.

[0039] (7) This application enables the molded part to remain stable during joint movement by means of double insertion of the insertion block and the insertion hole.

[0040] (8) This application uses the puppet joint and ball head connection in multiple ways to form the puppet skeleton, which can better simulate the human skeleton structure and bring players a rich entertainment experience. Attached Figure Description

Detailed Implementation

[0057] The embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art will recognize that the described embodiments can be modified in various ways or combinations thereof without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Furthermore, in this specification, the drawings are not drawn to scale, and the same reference numerals denote the same parts.

[0058] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Hinged connection" and "rotational connection" refer to a connection where the components can rotate relative to each other after connection. The phrase "two components forming an integrated structure through a one-piece molding process" means that during the formation of one of the two components, that component is connected to the other component without requiring further processing (such as bonding, welding, snap-fit ​​connection, or screw connection) to connect the two components. The directional terms mentioned in the embodiments of this application, such as "up," "down," "left," "right," "front," and "rear," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0059] Currently, for a puppet's joints to achieve rotational functionality, such as for the first and second connecting parts to rotate, a shaft hole needs to be machined in the first connecting part. A pivot is then used to assemble the first and second connecting parts, allowing them to rotate. Similarly, for the puppet's thigh and lower leg to achieve relative rotation, shaft holes need to be machined in both the thigh and lower leg, and a pivot is used to connect them for rotatable connection.

[0060] However, due to the small size of the pivot holes and the relatively small size of the joints, even using tweezers for installation is quite difficult, making the assembly and disassembly process less than smooth. The small size of the pivots also makes them easy to lose, preventing further assembly. Furthermore, the pivots can be confused with other pivots and are not easily distinguishable, thus compromising the experience for doll collectors.

[0061] This application provides a puppet joint that uses a holeless insert design. This eliminates the conventional through-hole on the hinged components, instead using a two-stage injection molding process to integrally form the hinge structure of two parts. In the first injection molding stage, a part is formed using a high-melting-point plastic material. This part is then placed into a second-stage injection mold, where it, together with the second-stage mold, forms the cavity for the second part. This two-stage injection molding process creates a non-detachable hinge structure between the two parts.

[0062] Furthermore, the puppet joints of this application are completely different from conventional joints; they are bidirectional joints, and the components connected to the connecting posts can rotate relative to the joints. This greatly simplifies the puppet assembly process, requiring only the insertion of, for example, the thigh and lower leg into the connecting posts to achieve relative rotation between the thigh and lower leg.

[0063] Please refer to Figure 1 , Figure 2 This application provides a puppet joint 40, including a connecting frame 10, which is a frame structure. Each end of the connecting frame 10 is hinged to a connecting post 20 via an integrally formed hinge shaft, allowing each connecting post to have a certain rotation angle. A pair of connecting posts 20 have their opposite ends hinged to the two ends of the connecting frame 10, while their opposing ends are used to mount parts that need to rotate relative to each other. For example, one connecting post connects to the upper arm, and the other connects to the forearm, allowing rotational freedom between the upper arm and forearm. Similarly, one connecting post connects to the thigh, and the other connects to the lower leg, allowing rotational freedom between the thigh and lower leg. This embodiment does not limit the connecting posts 20 to connecting only the puppet's limbs; they can also be used to connect two parts that require rotation.

[0064] The connecting frame 10 includes a pair of parallel, spaced-apart clamping plates 101, which together form a cavity for clamping the opposite end of the connecting post 20. The spacing between the clamping plates 101 can be adjusted according to the dimensions of the doll. For example, if the doll is larger, its joints will be relatively larger, and therefore the distance between the clamping plates 101 will be greater. If the doll is smaller, its joints will be relatively smaller, and therefore the distance between the clamping plates 101 will be smaller.

[0065] The pair of clamping plates 101 can have the same shape, and the surface of each clamping plate 101 is arc-shaped. Specifically, each clamping plate 101 can be two circular or approximately circular plates spaced apart, with the same side of the two circular plates connected by a straight line and the other side connected by an arc that curves inward between the circular plates, thus forming the arc-shaped surface of the clamping plate 101. The area where the circular plates of the pair of clamping plates 101 are located is used to clamp the opposite end of the connecting column 20. The connecting column is hinged to the first and second clamping plates in this area, giving the connecting column a rotational function.

[0066] The opposite edges of the two clamping plates 101 can have a smooth, rounded transition, which improves the smoothness of their shape curves, reduces interference with other parts, and prevents the player's fingers from being scratched by sharp edges during assembly.

[0067] A connecting portion 103 is provided between a pair of clamping plates 101 to connect the pair of clamping plates 101 into one unit. The connecting portion 103 is not limited to a single location; there may be multiple connecting portions between a pair of clamping plates 101, as long as they do not interfere with the rotation of the connecting post 20. For example, connecting portions 103 may be provided on both identical sides of a pair of clamping plates 101.

[0068] For example, the connecting portion 103 does not extend beyond the projected area of ​​the pair of clamping plates 101 to prevent interference with other parts. Please refer to... Figure 3 The left side of the pair of clamping plates 101 is an arc that curves inward between the circular plates. Therefore, the projection edge of the connecting part 103 on the clamping plate 101 is also an arc that curves inward between the circular plates, forming a flush outer edge. Similarly, the right side of the pair of clamping plates 101 is a straight line, so the projection of the connecting part 103 on the clamping plate 101 is also a straight line, forming a flush outer edge. The specific size of the connecting part 103 is not limited here and can be set as needed. The size of the connecting part 103 will limit the rotation angle of the connecting post 20. A larger rotation angle is desired, so the size of the connecting part 103 should be smaller; a smaller rotation angle is not required, so the size of the connecting post 103 can be larger. This is a conventional design approach and will not be described in detail here.

[0069] The clamping plate 101 and the connecting plate 202 form a hinge structure by means of shaft hole fit. A hinge shaft can be fixedly connected to the clamping plate 101 and a shaft hole can be provided on the connecting plate, or a shaft can be provided on the connecting plate and a hole can be provided on the clamping plate 101.

[0070] For example, a pair of hinge shafts 102 perpendicular to the plate surfaces can be provided on the opposing surfaces of a pair of clamping plates 101. Each hinge shaft 102 can be fixedly connected to both ends of the pair of clamping plates 101, such as... Figure 2As shown. The hinge shaft 102 is used to hinge with the connecting post 20, so that the connecting post 20 has a rotatable function.

[0071] Please refer to Figure 4 The connecting post 20 includes a connecting disc 202 and a plug-in post 201. The connecting disc 202 is disc-shaped with a central shaft hole, and its axis is coaxial with the hinge shaft 102. The connecting disc 202 is hinged to the hinge shaft 102 through its shaft hole, allowing the connecting disc 202 to rotate around the hinge shaft 102. Specifically, the hinge shaft 102 passes through the connecting disc 202, thereby rotatably connecting the connecting disc 202 and the hinge shaft 102.

[0072] Alternatively, a hinge shaft 102 can be fixedly connected to the connecting plate 202, while the clamping plate 101 does not have a hinge shaft. The connecting plate 202 and the clamping plate 101 can also be hinged by inserting the hinge shaft 102 on the connecting plate 202 into the clamping plate 101.

[0073] Regardless of whether the hinge shaft 102 is located on the connecting plate or the clamping plate 101, a non-removable hinge connection can be formed between the clamping plate 101 and the connecting plate through secondary injection molding. The connecting pillars and connecting frames can be processed into puppet joints using plastic materials with different melting points through secondary injection molding. A high-temperature melting-point plastic material is used as the base for the first molding, and then a low-melting-point plastic material that is immiscible with the two materials is used for the second injection molding, thus forming a joint by hinged connecting pillars and connecting frames. This processing method allows for the movement of multiple parts in puppet joints without the need for assembly.

[0074] During injection molding, the injection cavity is typically the gap formed when the moving mold and the fixed mold close. These gaps are filled by molten plastic during injection to form the injection-molded product. In this embodiment, the connecting frame and connecting pillar are plastic components with different melting points that are not mutually fusible. After the high-melting-point component is injection molded in one step, it is placed in the injection cavity of the low-melting-point component. The high-melting-point component, together with the moving and fixed molds, forms the injection cavity of the low-melting-point component. Because the injection temperature of the low-melting-point component is lower than that of the high-melting-point component, the high-melting-point component does not melt during the injection of the low-melting-point component. Thus, the two components are integrally molded during the injection molding of the low-melting-point component.

[0075] For example, the connecting post 20 could be made of TPC and the connecting bracket 10 of POK, or the connecting post could be made of POK and the connecting bracket 10 of TPC. TPC is a high-strength plastic, while POK is a plastic resistant to both high and low temperatures. TPC is a thermoplastic composite material, and POK has a higher melting point than TPC. A pair of connecting posts can be first injection molded from POK material, such as... Figure 6As shown, a pair of connecting pillars are installed onto the fixed mold 70. When the moving mold 60 moves to close with the fixed mold 70, the pair of connecting pillars, the moving mold 60, and the fixed mold 70 together form the injection cavity 50 of the connecting frame. Since the connecting frame 10 already occupies part of the space between the pair of clamping plates 101 in the space after the moving mold and the fixed mold are closed, the injection liquid will only form the clamping plates 101, and form a connecting part 103 between the clamping plates 101. It will also enter the shaft hole of the connecting plate 202 to form a hinge shaft, thereby connecting the connecting frame 10 and the connecting pillars into one unit. TPC material is injected into the injection cavity 50 of the connecting frame, and a second injection molding is performed on the connecting pillars 20 to form the hinged connecting pillars and the connecting frame into a puppet joint. After torque testing, the joint has a lifespan of no less than 7000 cycles.

[0076] It should be noted that, for ease of processing, a pair of connecting pillars can be injection molded as a single unit with their axes parallel and placed on a fixed mold, and then cut and separated after a second injection molding. Alternatively, multiple pairs of connecting pillars can be simultaneously connected to multiple connecting frames. For example, as shown... Figure 7 , Figure 8 As shown, multiple pairs of connecting posts are arranged circumferentially on the inner annular runner 80 with the axes of the insert posts 201 parallel. Molten POK material is injected into the inner annular runner 80, forming the high-melting-point component surrounding the circumference of the inner annular runner 80 after injection molding (the inner annular runner is to be removed in the end). The multiple pairs of connecting posts connected to the inner annular runner are installed onto the fixed mold, and the mold is closed. The fixed mold, the inner annular runner, the high-melting-point component, and the moving mold constitute the injection cavity of multiple pairs of connecting frames. An outer annular runner 90 is provided around the outer annular runner, through which molten TPC material is injected into the injection cavity, thereby forming multiple pairs of one-piece molded puppet joints. The specific design of the moving mold and the fixed mold closing to form the injection cavity is a conventional design, and the specific design and operation will not be described in more detail here.

[0077] The axis of the plug-in post 201, which is integrally formed with the connecting disk 202, is perpendicular to the axis of the connecting disk 202. The plug-in post 201 is cylindrical, for example. The plug-in post 201 extends from the edge of the connecting disk 202 in a direction perpendicular to the axis of the connecting disk.

[0078] The insertion post 201 is used to insert into a part. To facilitate insertion and fixation of the part, an insertion boss 203 can be provided at the end of the insertion post 201. The insertion boss 203 is formed by chamfering the end of a cylinder with a diameter larger than that of the insertion post 201. The chamfer can be a rounded corner or a 45° chamfer. Please refer to [reference needed]. Figure 5Correspondingly, the part where it is inserted into the insertion post 201 has an insertion hole 30, and at the end of the insertion hole 30 is a blocking boss 301 with a diameter smaller than that of the insertion hole. The diameter of the insertion hole 30 is the same as the diameter of the insertion boss 203, and the diameter of the blocking boss 301 is the same as the diameter of the insertion post 201. When the insertion boss 203 is inserted into the insertion hole 30, the chamfer facilitates the insertion boss 203 passing through the blocking boss 301. After the insertion boss 203 passes through the blocking boss 301, the blocking boss 301 prevents the insertion boss 202 from retracting, thereby connecting the connecting post 20 to the part.

[0079] For example, the parts are an upper arm and a forearm, both of which have insertion holes at their ends. An insertion boss 203 of a connecting post 20 is installed onto the upper arm after passing through a blocking boss, and the insertion boss 203 of another connecting post 20 is installed onto the forearm after passing through a blocking boss. Because the connecting plate 203 and the clamping plate 101 are hinged, the connecting post 20 can rotate relative to the connecting frame 10, thereby allowing the upper arm to rotate relative to the puppet joint, and the forearm to rotate relative to the puppet joint.

[0080] Furthermore, the end of the plug is a hollow tube, and multiple axially extending grooves are evenly arranged on the plug in the circumferential direction, starting from its end face. This allows the end to contract during insertion, making it easier to insert.

[0081] This embodiment transforms the relative rotational connection between the upper arm and forearm into a system where the upper arm rotates relative to the puppet's joint, and the forearm rotates relative to the puppet's joint. This allows the connecting column and connecting frame 10 to form a rotatable joint. This structural design makes the joint versatile, applicable to various limbs and parts requiring rotational connection, thus expanding the joint's application range. Furthermore, by plugging in the limbs, the installation of the pivot is eliminated, greatly enhancing the player's experience.

[0082] Because the connector 201 is plugged into the part, it can also rotate within the connector hole 30 after plugging. Taking the forearm joint as an example, the forearm can rotate around the axis of the connecting plate, which is the action of raising the forearm. Furthermore, the forearm can also rotate around the axis of the connector 201, allowing it to rotate a certain angle around the axis of the connector hole during the lifting process. This gives the doll more movement characteristics and improves the player experience.

[0083] In some embodiments, such as Figure 9 , Figure 10As shown, the hinge shaft 102 has an arc-shaped protrusion 105 in the radial direction, or the arc-shaped protrusions 105 can be symmetrically arranged on both sides of the radial direction. Correspondingly, multiple grooves 204 are uniformly machined along the circumference on the radial inner side of the connecting plate 202, and the radius of the groove 204 is equal to the radius of the arc-shaped protrusion 105. The arc-shaped protrusion 105 is inserted into the groove 204, which can fix the angle of limb rotation. When the rotational force is large, the arc-shaped protrusion 105 comes out from the groove 204 and enters the next groove, thereby changing the rotation angle of the limb. In order to make the rotation effortless, the circumference of the arc-shaped protrusion 105 can also be provided with an arc, so that it can easily enter the next groove during rotation.

[0084] In some embodiments, a plug-in block 104 is also fixedly connected to the connecting portion 103 on one side of the connecting frame 10. Various shaped parts 80 can be plugged into the plug-in block 104. Any part suitable for the shape of the piling position during development can be plugged into and replaced on this plug-in block 104. For example, when the puppet joint connects the thigh and the lower leg, a knee shaped part can be plugged into the plug-in block 104; when the puppet joint connects the upper arm and the forearm, an elbow shaped part can be plugged into the plug-in block 104.

[0085] Among them, such as Figure 11 , Figure 12 As shown, the cross-section of the insertion block 104 is U-shaped. Specifically, its end face has a first recess 106. Correspondingly, the molding part 80 has a receiving hole with a first protrusion 801 inside. The first protrusion 801 is used to insert into the first recess 106 for mating. A second recess 802 is formed around the first protrusion 801 inside the receiving hole for mating with the outer periphery of the insertion block 104. When the insertion block 104 is inserted into the molding part, the first protrusion 801 and the first recess 106 are mated together, and the second recess 802 and the outer periphery of the insertion block 104 are mated together. Through this double mating, the loosening of the molding part during joint movement can be prevented.

[0086] Furthermore, protrusions 107 are provided on the outer side of the plug block 104, the inner side of the first recess 106, the outer side of the first protrusion 801, and the inner side of the second recess 802 to increase its plug-in reliability.

[0087] This application also provides a doll skeleton, including the doll joints as described above, wherein the doll joints are at least connected between the thigh and the lower leg, and between the upper arm and the forearm. Specifically, the opposite ends of the connecting posts 20 are respectively inserted into the insertion holes 30 of the upper arm and the forearm, and the opposite ends of the connecting posts 20 are respectively inserted into the insertion holes 30 of the thigh and the lower leg.

[0088] The structure of the doll's skeleton is described in detail below; please refer to [link / reference]. Figure 13 , 14The doll skeleton includes a three-way ball head 11, which includes two ball heads connected horizontally and back to back, and a ball head connected upward between the two ball heads. The three-way ball head 11 is used for the doll's hip position, the upper ball head is used to connect to the waist and abdomen connecting sleeve 23, and the ball heads on both sides are used to connect to the upper part of the thighs respectively.

[0089] Specifically, the upper end of the ball head sleeve 12 has a socket to accommodate the ball head, and the lower end has a plug-in post. The ball heads on both sides of the three-way ball head are connected to the sockets of one of the ball head sleeves 12. The plug-in post 201 at the lower end of the ball head sleeve is plugged into the upper part of the thigh. Specifically, the plug-in posts 201 of the two ball head sleeves 11 are plugged into the groin of one thigh. Ball head connection is a common technical method and will not be described in more detail here.

[0090] It should be noted that the distance between the two ball heads connected back to back in a three-way ball joint can be designed according to the hip size requirements of the doll's skeleton. If a wider hip is required, the distance between the two ball heads should be larger, and if a narrower hip is required, the distance between the two ball heads should be smaller.

[0091] The outer periphery of the thigh 16 also features multiple rectangular slots for inserting armor-shaped components. These components can be inserted as a single piece into multiple slots simultaneously, or multiple pieces can be inserted into different slots; no specific limitation is made here. The armor-shaped components can cover the ball-head cover 12, thus preventing it from being directly exposed and affecting aesthetics. The ball-head cover 12 ensures both a snug fit and the ability to support the weight of the upper body, preventing it from becoming loose.

[0092] The thigh 16 has insertion holes at both the top and bottom. The upper end connects to the insertion post 201 of the ball head sleeve 12, while the lower end connects to one insertion post 201 of the puppet joint. The other insertion post 201 of the puppet joint connects to the upper end of the lower leg. The insertion block 104 of the puppet joint can be used to insert armor-shaped parts. This is to ensure the integrity of the overall design and prevent the puppet joint from being exposed or showing any flaws.

[0093] The lower leg 17 can be a frustum-shaped cone, wider at the bottom than the top; this is just an example, it can also be a column with a constant cross-sectional dimension, or a frustum-shaped cone. Its outer periphery also has, for example, rectangular slots for positioning armor-shaped parts, allowing for the replacement of different armor-shaped parts. The lower end of the lower leg is connected to a ball head, which inserts into the doll's shoe 14. Specifically, the lower end of the lower leg connects to one end of a double ball head, and the other end of the double ball head connects to the ball head of the doll's shoe 14. The design of the doll's shoes varies depending on the character and will not be described here.

[0094] The rectangular slots on the thighs and calves are just examples; of course, they can also be round, square, or other shapes, as long as they can be inserted into the armor-shaped parts. Different armor-shaped parts can be replaced through insertion.

[0095] The above describes the skeletal structure of the doll from the waist to the shoes. The following section describes the upper part of the doll.

[0096] The neck armor component 21 can be designed according to specific styling needs. It has a ball head at both the upper and lower ends. Both the upper and lower ball heads can be inserted into the neck armor component 21. The upper ball head is used to connect with the doll's head. Component 22 is a cross-shaped connector. Its upper end connects to the ball head at the lower end of the neck armor component 21, and its lower end is fixedly connected to a ball head for connecting with the upper ball head of the waist connecting sleeve 23. The lower end of the waist connecting sleeve 23 connects to the upper ball head of the three-way ball head 11. This is the movable joint position connecting the doll's waist and abdomen, allowing the doll to perform bending, turning, leaning back, and swaying movements.

[0097] The cross connector has vertical connecting holes at both ends. A steel shaft passes through both the connecting holes and the shoulder connector 24, and the two shoulder connectors 24 are installed at both ends of the cross connector, thus forming a shoulder connector that can be turned outward.

[0098] The front and rear ends of the cross connector are raised in the shape of a cuboid, with holes on the cuboid for fixing the figure's chest armor. For example, a plug-in method can be used, so that the entire upper body armor will be well connected, thus completely enclosing the internal structure without interfering too much with the figure's range of motion.

[0099] The outer side of the shoulder connector 24 has a ball socket. The first shoulder frame 25 has a ball head radially fixedly connected to the hollow cylinder. The ball head is connected to the ball socket on the outer side of the shoulder connector 24. A second shoulder frame 26 is also provided on the outer periphery of the hollow cylinder of the first shoulder frame 25. The second shoulder frame 26 includes a perforated plate 261 and a ball head extending upward from the edge of the perforated plate. The perforated plate 261 fits against the outer periphery of the hollow cylinder with an arc that matches the arc of the hollow cylinder of the first shoulder frame 25. The deltoid muscle shaping piece of the doll's shoulder can be installed in place by inserting two integrally formed plugs into the hollow cylinder of the first shoulder frame 25 and the hole in the perforated plate of the second shoulder frame 26, respectively. The shoulder armor shaping piece of the doll can be installed on the second shoulder frame 26 by engaging the ball head at the upper end of the second shoulder frame 26 through its internal ball socket.

[0100] The upper arm and the deltoid muscle shaping piece of the puppet's shoulder are integrated. One of the aforementioned plug-in posts 201 of the puppet joint connects to the lower end of the upper arm, and the other plug-in post 201 of the puppet joint connects to the upper end of the forearm. The lower end of the forearm can be connected to the ball joint of the hand via a ball joint. Specifically, the lower end of the forearm is connected to one end of a double ball joint, and the other end of the double ball joint is used to connect to the ball joint of the puppet's hand. It should be noted that the aforementioned double ball joint refers to two ball joints connected back to back.
