[0024] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0025] The meaning of "and / or" described in this application means that the situations where each exists alone or both exist at the same time are included.

[0026] The meaning of "inside" and "outside" in this application refers to the direction from the surface to the center of the internal bearing relative to the crossbar itself, and the opposite direction is outside; it is not a specific limitation on the device mechanism of this application.

[0027] The term “connection” as used in this application may mean a direct connection between components or an indirect connection between components via other components.

[0028] The multi-layered fingertip gyroscope provided in the present application comprises Figure 1 Shown:

[0029] A central shaft 1, with end assemblies 5 at both ends;

[0030] The crossbar 2, which is rotatably mounted on the central axis 1, is disposed between the end assemblies 5 and rotates about the central axis.

[0031] The present invention can use a surface treatment process or a coloring process on one side of the horizontal bar to make it present an intermittent display effect; and directly process the other side of the horizontal bar to have a uniform display effect. Thus, when one side of the horizontal bar rotates to face the user, different pattern effects can be displayed. When three horizontal bars are set, the fidget spinner of the present invention can be rotated by the user's touch to display a single pattern. Figure 2 The upper hexagram or lower hexagram shown on the right. Figure 2 When the mode is set to 6 horizontal bars, the fingertip gyroscope of the present application can rotate and display all the hexagrams through the touch of the user.

[0032] In the present application, the number of crossbar assemblies may not be limited. When multiple crossbars are installed on the central axis, and different meanings are given to each crossbar accordingly, six crossbars can be used to form six hexagrams or other patterns. Each crossbar 2 can be provided with a groove at the center position of one side surface thereof in a direction parallel to the central axis 1, and the coloring of the groove part in each crossbar 2 is distinguished from the coloring of other parts of the crossbar. For example, the groove part in each crossbar 2 is painted with one color while the other parts of the crossbar are kept in other colors or vice versa; alternatively, the groove in each crossbar 2 can be polished smooth while the other parts of the crossbar are kept relatively rough, or vice versa. Thus, the present application can utilize the smoothness of the surface texture of the crossbar or utilize the different color patterns on both sides of the crossbar, or utilize the combination of the two to distinguish the different display effects of the yang hexagram and the yin hexagram, so that they can be combined to form the eight trigrams.

[0033] When using: the user pinches the upper and lower end components with fingers, so that each crossbar component can rotate freely without interfering with each other. Hit one side of all or part of the crossbar components with fingers to make them rotate freely. Then slowly put your fingers close to the edge of the crossbar component to stop the rotation of each crossbar component. At this time, the crossbar with a groove in the middle that rotates to the user is the Yin Yao, and the crossbar that is connected in the middle is the Yang Yao.

[0034] To ensure that the crossbar can rotate flexibly, the present application may provide an assembly hole in the center of the crossbar for the central axis 1 to pass through, embed a miniature ball bearing inside the crossbar assembly, pass it on the central axis to connect the crossbar 2 with the central axis 1 through a bearing.

[0035] Specifically, in order to position the bearings of each crossbar, the present application can fix the inner ring of the bearing 3 on the central shaft 1, and fix the outer ring of the bearing 3 inside the assembly hole of the crossbar 2. Positioning sleeves of different lengths are used to perform axial positioning between two adjacent crossbar assemblies and between the crossbar assembly and the end assembly, and the positioning sleeves 4 are used to limit the crossbars 2 and between the crossbar 2 and the end assembly 5 to maintain no direct friction contact.

[0036] Therefore, different patterns can be displayed on both sides of the crossbar assembly by spray painting, etc., and different meanings can be given accordingly. For example, one side of the crossbar assembly is set to pure black, representing the yang line in the Eight Diagrams, and the other side of the crossbar is set to the yin line pattern. In this way, when the six crossbar assemblies stop rotating, they can form six lines, forming upper and lower hexagrams.

[0037] Reference Figure 3 as well as Figure 2 , the present application can specifically configure the positioning sleeve 4 to include: an end positioning sleeve 41 abutting between the crossbar 2 and the end assembly 5, and a middle positioning sleeve 42 abutting between two adjacent crossbars 2;

[0038] One end of the end positioning sleeve 41 abuts against the end assembly 5, and the other end of the end positioning sleeve 41 abuts against the inner ring of the bearing 3;

[0039] The two ends of the middle positioning sleeve 42 between the cross bars are respectively in contact with the inner rings of the bearings 3 installed inside the two adjacent cross bars 2 .

[0040] When assembling the crossbar and the bearing, this application can adopt Figure 4 In the form shown, in the assembly hole provided at the center position of each crossbar, the inner diameter thereof is contracted inward from one end of the assembly hole to form a step structure in the assembly hole, the outer ring of the bearing 3 is fixedly provided on the step structure, and the bearing is fixed in the assembly hole by any of the following methods:

[0041] A tolerance is set between the assembly hole set in the center and the outer ring of the bearing 3, so that the outer ring of the bearing 3 and the assembly hole of the crossbar are interference-connected, and the bearing is fixed by knocking it into it, ensuring that the bearing and the crossbar are very tight and do not fall off;

[0042] Alternatively, the crossbar 2 may be injection molded using an overmolding process. Specifically, the bearing is pre-embedded in a mold used in the overmolding process, so that the bearing is directly connected to the crossbar 2 during the injection molding process.

[0043] In addition, a groove can be opened in the assembly hole at the center of the crossbar, a retaining ring is set on the side with a larger inner diameter in the assembly hole, and the retaining ring is clamped in the groove, so as to limit the axial position of the bearing in the assembly hole.

[0044] Therefore, the spacing between the crossbars, the first and last crossbars and the end assembly 5 can be limited by the positioning sleeve 4, and then the spacing between the bearings and the crossbars connected to the outside can be limited by the bearings.

[0045] The fidget gyroscope of the present application can also adopt the method of colored sheets, and the colored paddles are bonded to the side grooves of the horizontal bar assembly with an adhesive, so that the colored sheets are fixed on the front and rear surfaces of the horizontal bar in an even manner, without skew, and without overflowing glue or falling off. The horizontal bar assembly can then be knocked into the bearing, and the upper and lower end assemblies, as well as the copper tube used as a positioning sleeve, are inserted into the optical axis in sequence. The upper and lower end assemblies and the outermost horizontal bar assemblies are limited by corresponding upper and lower positioning sleeves, and the middle positioning sleeves are used between the adjacent horizontal bars set between the two end assemblies. The end assembly is transitionally matched with the processed optical axis, and an appropriate adhesive can also be used to bond the outer ring of the bearing to the internal assembly hole of the horizontal bar to prevent sliding and falling off between the two.

[0046] After assembly, the workpiece should have no defects in appearance, the components should be parallel to each other and evenly spaced, and the crossbar components and positioning sleeves should be pressed tightly without clearance or relative sliding. As a result, each crossbar component arranged along the central axis can rotate along the axis, and there is no abnormal sound, smoothness and consistency during the rotation process. During the rotation process, the spacing between the components can still be kept uniform and without deflection by means of positioning sleeves.

[0047] In summary, the present application sets horizontal bars with different display effects on both sides through the central axis, and uses the limiting effect of the positioning sleeve on the central axis to maintain the stacked horizontal bars in a state of free rotation without interference with each other. Therefore, the present application can increase the fun of the device by using a relatively simple, reliable and low-cost drop-off structure, and by using the randomly appearing surfaces with different display effects on the horizontal bars. The fidget spinner of the present application achieves interaction by moving the horizontal bars with fingers, and the action is novel. The different display effects of the horizontal bars can be used to give a lot of meaning, and can be used to assist in the dissemination of Zhouyi Bagua culture.

Although the present application is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
