DETAILED DESCRIPTION

[0023] For the convenience of those skilled in the art to understand, the utility model is further explained below in combination with examples and drawings, and the content mentioned in the implementation is not a limitation of the utility model. The utility model is described in detail below in combination with drawings.

[0024] Example 1

[0025] As Figures 1 to 3 shown, the utility model provides a flint 62 gyroscope, including shell 1, rotating gear 2, fixed structure 3, hold shell 4, friction piece 5 and multiple flint structure 6, rotating gear 2 is installed in shell 1, fixed structure 3 is arranged between shell 1 and rotating gear 2, multiple flint structure 6 is all arranged at the bottom of hold shell 4, friction piece 5 is installed in shell 1 and is opposite flint structure 6;

[0026] The top of shell 1 is provided with n catches 11, hold shell 4 is provided with n clamping grooves 41, and the n catches 11 and the n clamping grooves 41 are one-to-one corresponding clamped;N is not less than 2 natural number.

[0027] Taking n=3 of the embodiment as an example, a three-point positioning structure is formed, so as to ensure the stability of the connection between the shell 1 and the hold shell 4. In use, the user drives the utility model to rotate, because the utility model will inevitably shake / oscillate during rotation, so that the flint structure 6 and the friction piece 5 will collide and separate after the collision, thereby continuously generating spark effect without spring.

[0028] In the embodiment, the width of the clamping groove 41 is greater than the width of the catch 11, and the height of the end of the clamping groove 41 is greater than the height of the first end of the clamping groove 41;The catch 11 is clamped at the first end of the clamping groove 41. That is, there is a certain gap between the catch 11 and the clamping groove 41, so as to ensure a certain amount of movement under the premise that the catch 11 stably hooks the first end of the clamping groove 41, so that the utility model is more likely to float and ensure the generation of spark effect.

[0029] In the embodiment, the flint structure 6 includes a floating shell 61 and multiple flints 62, the floating shell 61 is arranged between the friction piece 5 and the hold shell 4, the side wall of the floating shell 61 is provided with multiple floating arms 63, and the multiple flints 62 and the multiple floating arms 63 are one-to-one assembled;Rotating gear 2 is provided with synchronous shaft 21, and synchronous shaft 21 is connected to floating shell 61 after passing through friction piece 5;

[0030] The floating arm 63 is used to drive the flint 62 and the friction piece 5 to rub to complete the spark when the shell 1 rotates.

[0031] Specifically, the number of flints 62 is preferably n to achieve a relatively obvious spark effect. The flints 62 are installed on the floating shell 61 so that there is a floating amount between the holding shell 4 and the floating shell 61. Thus, when the outer shell 1 shakes / oscillates, the holding shell 4 shakes / oscillates with a smaller amplitude due to inertia than the outer shell 1, and the floating shell 61 shakes / oscillates with a smaller amplitude due to inertia than the holding shell 4. This achieves the effect of making it easier for the flints 62 to contact the friction element 5 and generate friction.

[0032] Specifically, the floating shell 61 is provided with an insertion hole 64, and the holding shell 4 is provided with an insertion post 45, which is inserted into the insertion hole 64; the insertion post 45 is provided with a slot 46, and the synchronous shaft 21 is inserted into the slot 46. That is, in this utility model, the rotating gear 2 rotates under external drive, and it connects the outer shell 1, the holding shell 4 and the floating shell 61 through the synchronous shaft 21, ensuring more stable and longer-lasting rotation.

[0033] In this embodiment, the outer casing 1 is provided with a drive hole 12, through which the rotating gear 2 is exposed. The drive hole 12 is used to allow the external drive rack 7 to pass through. That is, the drive hole 12 is used to allow the drive rack 7 to be inserted into and mesh with the rotating gear 2. Then, by quickly pulling the drive rack 7, the rotating gear 2 can be driven to rotate, thereby realizing the drive rotation of this utility model.

[0034] In this embodiment, a support part 13 is provided at the bottom of the outer shell 1, a transmission ring 15 is fixed inside the outer shell 1, and the rotating gear 2 has a transmission part 22, which is installed inside the transmission ring 15.

[0035] Compared with the prior art, the bottom of the outer shell 1 of this utility model is sealed, that is, the transmission part 22 at the bottom of the rotating gear 2 is simply housed inside the transmission part 22. The fulcrum of rotation of this utility model is still the support part 13 at the bottom of the outer shell 1, so that the rotating gear 2 drives the outer shell 1 to rotate by rotating inside the outer shell 1. This can reduce the wear of the transmission part 22 when it is used as a shaft.

[0036] Of course, during the driving process, since the person holds the outer shell 1 and uses the drive rack 7 to drive the rotating gear 2, the rotating gear 2 can still rotate while the person holds the outer shell 1. At this time, the outer shell 1 does not rotate due to the interference of the person's force, which causes the force of the rotating gear 2 to be transmitted to the friction component 5 and other components, causing the components to float and rub against the flint structure 6, thus generating sparks. After the person releases the outer shell 1, the outer shell 1 falls to the ground and can rotate under the drive of the rotating gear 2, and the flint structure 6 rubs against the friction component 5 by floating.

[0037] Example 2

[0038] like Figure 4 and Figure 5As shown, the embodiment compared with the embodiment 1, the difference is mainly in the pressing shell 4, specifically: the pressing shell 4 includes a main body 42, 2n hollow parts 43 and 2n displacement parts 44, 2n hollow parts 43 are arranged in the main body 42 in a circular array with the main body 42 as the center, 2n hollow parts 43 are arranged on the side wall of the main body 42, the displacement part 44 is connected to the adjacent two hollow parts 43 on both sides, the clamping groove 41 is arranged on the connecting part, and the adjacent clamping grooves 41 have a connecting part without clamping grooves 41;

[0039] The floating arm 63 is located directly below the hollow part 43.

[0040] That is, the hollow part 43 realizes the displacement of the floating arm 63, so that the synchronization of the floating arm 63 and the pressing shell 4 can be further reduced, the amplitude and frequency of floating are increased, so that the spark effect is better.

[0041] The remaining structures, such as the insertion column 45 and the insertion slot 46 of the pressing shell 4, are the same as those of the embodiment 1, so the corresponding structures of the embodiment 1 can be referred to in the embodiment, and will not be described here.

[0042] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application is disclosed as above, it is not intended to limit the present application. Any skilled person in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the present application, and any equivalent embodiment with equivalent changes is equivalent to the above embodiment.
