Description

Technical Field

[0001] This utility model relates to the field of gyroscope technology, specifically to a novel dual-linkage gyroscope structure. Background Technology

[0002] Fidget spinners are common toys on the market today. They consist of a symmetrical body that can be rotated in two or more directions, with a bearing embedded in the middle of the body, allowing it to spin freely on the finger.

[0003] Current fidget spinners can only rotate the outer structure, which limits their fun factor. Based on this, this solution provides a new type of dual-linkage gyroscope structure that can achieve coordinated rotation of the inner and outer structures, increasing the overall playability. Utility Model Content

[0004] The present invention aims to at least solve the problem in the prior art where only the outer structure is rotatable.

[0005] This solution provides a novel dual-linkage gyroscope structure, achieved through the following specific technical means: including an inner rotor and an outer rotor rotatably mounted on the inner rotor;

[0006] It also includes a rod body, in which an inner shaft is rotatably mounted, and the top end of the inner shaft extends from the top opening of the rod body and is fixedly connected to the inner rotor, realizing the rotational linkage of the inner and outer layers.

[0007] Preferred technical solution 1: A ball groove is provided on the outer circumference of the inner rotor, and a ball is placed in the ball groove, with the ball in contact with the inner wall of the outer rotor.

[0008] Preferred technical solution 2: A ball groove 2 is formed around the bottom side of the inner wall of the outer rotor, and the ball groove 2 is also used to place balls, with the top of the balls in the ball groove 2 contacting the bottom wall of the inner rotor.

[0009] Preferred technical solution 3: A press-type stop component is installed on the rod body, which is used to control the inner shaft to stop rotating.

[0010] Preferred technical solution four: The top end of the inner shaft is detachably connected to the inner rotor, such as by threaded assembly.

[0011] The above structure gives this solution the following advantages:

[0012] 1. Increase grip comfort by utilizing the design of the rod;

[0013] 2. The dual-linkage structure allows both the inner and outer rotors to rotate, increasing the overall fun.

[0014] 3. Modular assembly can be achieved by replacing different styles of inner and outer rotors. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-2 and Figure 4 The novel dual-linkage gyroscope structure includes an inner rotor 1 and an outer rotor 2 rotatably mounted on the inner rotor 1, with the inner rotor 1 and the outer rotor 2 connected by a bearing 6.

[0025] It also includes a rod body 3, with an inner shaft 4 rotatably mounted inside the inner cavity of the rod body 3. A bearing 6 is also provided between the inner shaft 4 and the rod body 3. The top end of the inner shaft 4 extends from the top opening of the rod body 3 and is fixedly connected to the inner rotor 1. The top end of the inner shaft 4 is detachably connected to the inner rotor 1, such as by threaded assembly, so as to realize the replacement of the inner rotor 1 and the outer rotor 2. It can be replaced and assembled with other fidget spinners with different appearances to enrich the overall appearance. When in use, when holding the rod body 3 and rotating the outer rotor 2, the friction between the inner rotor 1 and the outer rotor 2 will cause the inner rotor 1 to rotate as well, thereby realizing the dual linkage of the inner and outer layer structures.

[0026] Please see Figures 3-5 The novel dual-linkage gyroscope structure has a ball groove 11 on the outer circumference of the inner rotor 1. The ball groove 11 is used to hold balls. The ball groove 11 is an inclined groove with the groove opening tilted downwards, which can make the balls in the ball groove 11 contact the inner wall of the outer rotor 2. When the outer rotor 2 rotates, the balls collide back and forth between the inner rotor 1 and the outer rotor 2 to drive the inner rotor 1 to rotate, thus providing power for the rotation of the inner rotor 1.

[0027] The inner wall of the outer rotor 2 is provided with a ball groove 21 around the inner rotor 1. The ball groove 21 is also used to place balls. The top of the balls in the ball groove 21 contacts the bottom wall of the inner rotor 1. The balls in the ball groove 11 and the ball groove 21 collide up, down and left and right between the inner rotor 1 and the outer rotor 2 to realize the transmission of rotational force.

[0028] Please see Figures 1-2 A novel double-linkage gyroscope structure is described, in which a press-type stop component 5 is installed on the rod body 3. The press-type stop component 5 is used to pass through the rod body 3 and contact the inner shaft 4 to stop the rotating inner shaft 4. An installation groove 31 is provided on the wall of the rod body 3. The press-type stop component 5 includes a press component 51 slidably disposed in the installation groove 31. A protruding rod 52 fixed at the inner end of the press component 51 slides through the rod body 3 and intermittently contacts the inner shaft 4. An elastic component 53, preferably a spring, is connected between the press component 51 and the inner end wall of the installation groove 31. The rebound of the elastic component 53 controls the protruding rod 52 to move away from the inner shaft 4. When it is necessary to stop the inner rotor 1, the press component 51 can be pressed to make the protruding rod 52 contact the inner shaft 4.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
