Description

Technical Field

[0001] This utility model relates to the field of toy transmission technology, and in particular to a wire-pull joint and a pterosaur toy. Background Technology

[0002] Currently, pterosaur toys are widely loved by consumers. Pterosaur toys on the market use a structure where the neck can rotate and the wings can swing to simulate the pterosaur's head turning or flying movements, making the pterosaur toys appear more realistic. However, the necks of existing pterosaur toys are all designed with a motor to drive the neck to rotate in one direction. Such a design has the problems of low simulation, poor playability, and weak product appeal.

[0003] There is no effective solution yet to address the problem that the necks of pterosaur toys in existing technologies can only rotate in one direction, resulting in poor realism and playability. Utility Model Content

[0004] In view of this, it is necessary to provide a wire-pull joint to at least solve the problem that the neck of pterosaur toys in the related technology can only rotate in one direction, resulting in poor simulation and playability.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] See Figure 1-7In one aspect, embodiments of this application provide a wire-operated joint, which includes a first limiting device 100, a second limiting device 200, a plurality of ball joints 300, and a wire-operated transmission assembly 400. The plurality of ball joints 300 are disposed between the first limiting device 100 and the second limiting device 200. Each ball joint 300 includes a housing 31, a movable rod 32, a ball-shaped joint head 33, and a cup-shaped joint socket 34. The housing 31 covers the exterior of the movable rod 32. The ball-shaped joint head 33 is located at one end of the movable rod 32, and the cup-shaped joint socket 34 is located at the other end of the movable rod 32. The cup-shaped joint of the previous group of ball joints 300... The socket 34 is rotatably covered on the ball joint head 33 of the rear ball joint 300. The cable pull transmission assembly 400 includes a cable pull drive device 41 and a transmission cable 42. The cable pull drive device 41 is located on one side of the second limiting device 200. One end of the transmission cable 42 is connected to the cable pull drive device 41, and the other end of the transmission cable 42 passes through the second limiting device 200 and the outer shell 31 and is fixedly connected to the first limiting device 100. The cable pull drive device 41 pulls the transmission cable 42, thereby driving several sets of ball joints 300 to swing between the first limiting device 100 and the second limiting device 200.

[0021] It should be noted that with this design, the pterosaur toy's neck, through the structural design of several sets of ball joints 300 and the cable pull transmission assembly 400, under the drive of the cable pull drive device 41, drives the transmission cable 42 to pull the cup-shaped joint sockets 34 of several sets of ball joints 300 to rotate at the ball joint head 33, thereby realizing the function of multi-angle rotation of the pterosaur toy's neck. This replaces the existing pterosaur toy's neck structure design that can only rotate in one direction, resulting in higher simulation, stronger attraction, and greater playability.

[0022] In order to achieve the purpose of limiting and fixing the front end of several sets of ball joints 300, in some optional embodiments, the first limiting device 100 includes a first limiting bracket 11 and a cup-shaped joint limiting socket 12. The first limiting bracket 11 is disposed at the front end of several sets of ball joints 300, and the cup-shaped joint limiting socket 12 is disposed on the first limiting bracket 11. The cup-shaped joint limiting socket 12 can rotatably cover the ball joint head 33 of the foremost set of ball joints 300.

[0023] In order to achieve the purpose of limiting and fixing the rear end of several sets of ball joints 300, in some optional embodiments, the second limiting device 200 includes a second limiting bracket 21 and a ball joint limiting head 22. The second limiting bracket 21 is disposed at the rear end of several sets of ball joints 300, and the ball joint limiting head 22 is disposed on the second limiting bracket 21. The cup-shaped joint socket 34 of the last set of ball joints 300 can be rotatably covered by the ball joint limiting head 22.

[0024] It should be noted that with this configuration, a cup-shaped joint limiting socket 12 is provided in the first limiting bracket 11 to receive and limit the ball joint head 33 of the first group of ball joints 300, and a ball joint limiting head 22 is provided in the second limiting bracket 21 to receive and limit the cup-shaped joint socket 34 of the last group of ball joints 300. This allows several groups of ball joints 300 to rotate and swing stably between the first limiting device 100 and the second limiting device 200, thus extending their service life.

[0025] To achieve the purpose of stably driving several sets of ball joints 300 to rotate and swing, in some optional embodiments, the transmission rope 42 includes a first rope 421, a second rope 422, a third rope 423, and a fourth rope 424. Each of the first rope 421, the second rope 422, the third rope 423, and the fourth rope 424 has a limiting block 425 at its front end. The first limiting bracket 11 is provided with a stop for the first rope 421, the second rope 422, the third rope 423, and the fourth rope 424. The first rope 421, the second rope 422, the third rope 423 and the fourth rope 424 pass through the clearance hole. The front ends of the first rope 421, the second rope 422, the third rope 423 and the fourth rope 424 are engaged with the clearance hole by the limiting block 425 and the first limiting bracket 11. The second limiting bracket 21 is provided with a limiting groove. The rear ends of the first rope 421, the second rope 422, the third rope 423 and the fourth rope 424 are embedded in the second limiting bracket 21 by the limiting groove.

[0026] It should be noted that this configuration, with the use of four sets of transmission ropes 42, makes the structure more stable. The limiting block 425 can limit the connection between the first rope 421, the second rope 422, the third rope 423 and the fourth rope 424 and the first limiting bracket 11, maintaining flexibility while limiting the first rope 421, the second rope 422, the third rope 423 and the fourth rope 424.

[0027] To further achieve the purpose of stably driving several sets of ball joints 300 to rotate and swing, in some optional embodiments, the outer shell 31 includes a first outer shell 311 and a second outer shell 312, with a fixing hole 313 formed between the first outer shell 311 and the second outer shell 312. The first outer shell 311 and the second outer shell 312 cover the outside of the movable rod 32 through the fixing hole 313. The first outer shell 311 and the second outer shell 312 are provided with limiting holes 314 around the fixing hole 313 for the first rope 421, the second rope 422, the third rope 423 and the fourth rope 424 to pass through. The first rope 421, the second rope 422, the third rope 423 and the fourth rope 424 drive the outer shell 31 and the movable rod 32 to swing between the first limiting bracket 11 and the second limiting bracket 21 through the limiting holes 314.

[0028] It should be noted that with this configuration, the first rope 421, the second rope 422, the third rope 423, and the fourth rope 424 pass through several sets of ball joints 300 through the limiting holes 314, thereby providing a power source for the relative rotation and swing of the several sets of ball joints 300. The use of limiting holes 314 in four directions (up, down, left, and right) can effectively prevent the outer shell 31 from deviating, and the swing and rotation accuracy is higher.

[0029] To achieve the purpose of the transmission cord 42 pulling several sets of ball joints 300 to rotate and swing, in some optional embodiments, the cord pulling drive device 41 includes a drive motor 411 and a cord swing block 412. The cord swing block 412 is disposed on the rotating shaft of the drive motor 411, and cord fixing bolts 413 are provided at both ends of the cord swing block 412. The first cord 421, the second cord 422, the third cord 423 and the fourth cord 424 are wound on the cord fixing bolts 413. The drive motor 411 drives the cord swing block 412 to swing by rotating, thereby pulling the first cord 421, the second cord 422, the third cord 423 and the fourth cord 424 to make the outer shell 31 and the movable rod 32 swing between the first limiting bracket 11 and the second limiting bracket 21.

[0030] It should be noted that with this configuration, the cable pull drive device 41 uses a drive motor 411 as the power source, which has high precision. The drive motor 411 drives the cable swing block 412 to swing through the rotating shaft, thereby accurately pulling each group of transmission cables 42, including the first cable 421, the second cable 422, the third cable 423, and the fourth cable 424, thus improving precision and stability.

[0031] Secondly, this application also provides a pterosaur toy, including a torso body 500, a head 600 and wings 700. A wire pull joint is provided between the torso body 500 and the head 600. The wire pull joint includes the wire pull joint described in the first aspect. A second limiting device 200 and a wire pull transmission assembly 400 of the wire pull joint are provided on the torso body 500, and the head 600 is provided on the first limiting device 100.

[0032] It should be noted that with this setup, a wire joint is installed between the torso 500 and the head 600 to simulate the pterosaur's head-shaking and neck-twisting state. The wire joint can swing and rotate at multiple angles, resulting in a higher degree of simulation.

[0033] To simulate the action of a pterosaur opening its mouth, in some alternative embodiments, the head 600 includes an upper jaw 61, a lower jaw 62, and an opening and closing transmission assembly 63. The upper jaw 61, the lower jaw 62, and the opening and closing transmission assembly 63 are all located at the front end of the first limiting device 100. The lower jaw 62 is located below the upper jaw 61, and the upper jaw 61 and the lower jaw 62 are connected by the opening and closing transmission assembly 63. The lower jaw 62 can open and close at the lower end of the upper jaw 61 through the opening and closing transmission assembly 63. By using the opening and closing transmission assembly 63 to realize the opening and closing action between the upper jaw 61 and the lower jaw 62, the dynamic of a pterosaur opening or closing its mouth is simulated.

[0034] To simulate the flight motion of a pterosaur, in some optional embodiments, the wing 700 includes a wing drive device 71, a wing transmission device 72, and a swing bracket 73. The wing drive device 71, the wing transmission device 72, and the swing bracket 73 are all mounted on the torso body 500. The wing transmission device 72 is located at the front end of the wing drive device 71, and the swing bracket 73 is located on both sides of the wing transmission device 72. The wing drive device 71 and the swing bracket 73 are connected by the wing transmission device 72. The wing drive device 71 drives the swing bracket 73 to swing on both sides of the torso body 500 through the wing transmission device 72, thereby simulating the flight motion of a pterosaur.

[0035] In some alternative embodiments, the wing drive device 71 is a servo motor, and the wing transmission device 72 is a transmission gear set.

[0036] It should be noted that with this configuration, the wing drive device 71 uses a servo motor as its power source, which has high precision, and the wing transmission device 72 uses a transmission gear set, which further improves the transmission precision.
