Description

Technical Field

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

[0002] Among the known movable joints in humanoid dolls, figures, and models, the general-purpose joints for parts such as feet, shoulders, and necks are not perfect. Usually, the upper and lower plates of the joints are fixed in shape by the friction between the materials. When the shape is fixed for a long time, wear and tear will cause insufficient friction, resulting in poor shape fixation. It is difficult to maintain support or fix high-difficulty movements, especially when adding equipment or holding weapons. The arms, feet, and other parts cannot support the weight, causing the movable parts to deform and shift, and failing to achieve the ideal state. Utility Model Content

[0003] The purpose of this invention is to provide a novel movable locking joint structure to solve the technical problems of insufficient friction due to wear and imperfections in the use of general-purpose joints in the prior art.

[0004] To solve the above-mentioned technical problems, this utility model provides a novel movable locking tooth joint structure, including a lower cover plate and an upper cover plate, which can be interlocked together. A recessed locking tooth groove is fixedly provided on the lower cover plate, and a protruding fixing post is vertically fixed at the center of the locking tooth groove. An anti-detachment ring is movably connected to the top of the fixing post.

[0005] Preferably, the upper cover plate is provided with a mounting hole, which is a through hole for the fixing post to pass through. The diameter of the mounting hole is larger than the diameter of the fixing post and smaller than the diameter of the anti-detachment ring. The mounting hole can rotate horizontally on the fixing post, and an anti-detachment buckle is provided in the mounting hole.

[0006] Preferably, a protruding retaining ring is fixed around the mounting hole, the retaining ring has evenly distributed retaining teeth, the size of the retaining ring and the size of the retaining groove are completely matched, and the retaining ring can be completely engaged into the retaining groove.

[0007] Preferably, the lower cover plate is also fixedly connected to a connecting handle in the horizontal direction, and the other end of the connecting handle is provided with a connecting post. Next to the connecting post is a recessed anti-detachment ring for engaging with the upper arm or foot of the doll. The diameter of the anti-detachment ring is smaller than the diameter of the connecting post.

[0008] Preferably, the upper cover plate is also fixedly connected to a connecting ball or a connecting handle in the horizontal direction, which can be snapped together with the lower cover plate to form two types of snap-tooth joint structures.

[0009] Preferably, the fixing column is cylindrical.

[0010] Preferably, the connecting handle may be curved.

[0011] Preferably, the top view cross-section of the tooth is any one of a semi-circular, trapezoidal, square, or rectangular structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention employs a gear-like interlocking tooth structure, which provides a stronger mechanical locking effect compared to traditional methods that rely on material friction for fixation. The tooth structure, similar to the interlocking teeth on a gear, allows the teeth to mesh alternately, increasing friction and locking force. This enables the device to withstand greater forces, making the joints less prone to rotation or displacement under load. Even when bearing the extra weight of weapons or equipment, the joints are less likely to rotate or shift due to force, ensuring the puppet maintains highly difficult poses. Traditional joints experience decreased friction due to wear after long-term use, but the tooth structure, through mechanical meshing, significantly reduces the impact of wear on its locking effect.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0018] like Figure 1-6 As shown, this utility model provides a novel movable locking joint structure, including a lower cover plate 1 and an upper cover plate 5. The lower cover plate 1 and the upper cover plate 5 can be interlocked to form a movable joint. A recessed locking groove 101 is fixedly provided on the lower cover plate 1, and a protruding fixing post 2 is vertically fixed at the center of the locking groove 101. An anti-disengagement ring 201 is movably connected to the top of the fixing post 2. The fixing post 2 serves a positioning function.

[0019] Furthermore, the upper cover plate 5 is provided with a mounting hole 6, which is a through hole for the fixing post 2 to pass through. The diameter of the mounting hole 6 is larger than the diameter of the fixing post 2 and smaller than the diameter of the anti-detachment ring 201. The mounting hole 6 is sleeved on the fixing post 2 and can rotate horizontally. An anti-detachment buckle 601 is provided in the mounting hole 6.

[0020] Furthermore, a protruding retaining ring 501 is fixedly provided around the mounting hole 6. The retaining ring 501 has evenly distributed retaining teeth. The size of the retaining ring 501 and the size of the retaining groove 101 are completely matched. The retaining ring 501 can be completely engaged into the retaining groove 101.

[0021] Furthermore, the lower cover plate 1 is also fixedly connected to a connecting handle 3 in the horizontal direction. The other end of the connecting handle 3 is provided with a connecting post 301. Next to the connecting post 301 is a recessed anti-detachment ring 302 for engaging with the upper arm or foot of the doll. The diameter of the anti-detachment ring 302 is smaller than the diameter of the connecting post 301.

[0022] Furthermore, the upper cover plate 5 is also fixedly connected to a connecting ball 4 or a connecting handle 3 in the horizontal direction, which can be snapped together with the lower cover plate 1 to form two different movable locking joint structures.

[0023] Furthermore, the fixed column 2 is cylindrical.

[0024] Furthermore, the shape of the connecting handle 3 can be elongated or curved.

[0025] Furthermore, the top view cross-section of the tooth is any one of other polygonal structures such as semicircle, trapezoid, square, or rectangle.

[0026] Working principle: When using the movable locking tooth joint structure of this utility model, the entire joint structure is first assembled. The locking tooth ring is engaged with the fixing post 2 through the mounting hole 6, and the locking tooth ring is engaged in the caliper groove. With the help of the anti-detachment ring 201, the stability of the connection between the upper cover plate and the lower cover plate can be guaranteed.

[0027] After the joint structure is assembled, in actual use, when the joint needs to be rotated, simply rotate the connecting stake. When the force on the connecting stake is greater than the friction and locking force between the locking teeth, the movable joint connecting ball or connecting handle can be rotated, thereby achieving the joint adjustment function. After rotation, the joint stability can be ensured by the friction and locking force between the locking teeth. At this time, under the leverage principle, the joint's load-bearing capacity is increased several times, allowing the joints of the figure model, such as the shoulders and feet, to withstand stronger forces and maintain the movement without deformation. This allows for the assembly of heavier weapons, accessories, and items, enabling the placement of more difficult poses and providing a strengthening effect in maintaining and fixing the pose.

[0028] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model adopts a gear-like interlocking tooth structure, which provides a stronger mechanical locking effect compared to the traditional method of fixing by material friction. The tooth structure, similar to the interlocking teeth on a gear, allows the teeth to interlock in an alternating manner, increasing friction and locking force. This enables the device to withstand greater forces, making the joints less prone to rotation and displacement under stress. Even when bearing the additional weight of weapons, equipment, etc., the joints are less likely to rotate or shift due to force, ensuring the puppet maintains highly difficult poses. Traditional joints experience a decrease in friction due to wear after long-term use, while the tooth structure, through mechanical meshing, significantly reduces the impact of wear on its locking effect.
