[0037] Example 2

[0038] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 10 As shown below, see details:

[0039] In a preferred embodiment, the first extension bracket 3 includes a first double-grooved gear 6, the top of which meshes with a first triple-grooved gear 7. All the large gears used have the same structure, and the small gears also have the same structure. During meshing, the insertion slot 1604 provided above the first triple-grooved gear 7 connects with the insertion connectors 1605 of other gears, thus completing the connection of the corresponding gears. During the connection, the corresponding gears mesh with each other, thereby completing the fixation and connecting the transmission path. A second triple-grooved gear 8 meshes above the first triple-grooved gear 7, a first multi-grooved gear 9 meshes above the second triple-grooved gear 8, a second double-grooved gear 10 meshes on the side of the first multi-grooved gear 9, a third double-grooved gear 11 meshes above the second double-grooved gear 10, and a first head assembly 12 meshes above the third double-grooved gear 11.

[0040] In a preferred embodiment, the first head assembly 12 includes a first rotating ring 32, a semi-circular shell 1201, a toothed piece 1202, and a connector 1203. Two sets of semi-circular shells 1201 are connected to the side of the first rotating ring 32. When the first rotating ring 32 receives the upward transmission power from the gear path and drives its own gear ring 3204 to rotate, the first rotating ring 32 drives the toothed piece 1202 inside the semi-circular shell 1201 to rotate, thereby realizing the connection of the toy. The toothed piece 1202 is connected through the connector 1203, thereby completing the connection of the toothed piece 1202. The toothed piece 1202 is placed between the two sets of semi-circular shells 1201, and the connector 1203 is provided between the two sets of semi-circular shells 1201 and the toothed piece 1202.

[0041] In a preferred embodiment, the first rotating ring 32 includes a fixed outer shell 3201, and a micro gear 3202 is rotatably connected to the side of the fixed outer shell 3201. The teeth of the micro gear 3202 mesh with the gear ring 3204. A first outer shell 3203 is installed on the side of the micro gear 3202, and the gear ring 3204 is connected to the side of the first outer shell 3203. When the gear ring 3204 transmits power to the micro gear 3202, the locking pin 3205 connected to the micro gear 3202 drives the toothed plate 1202 to rotate. The locking pin 3205 is movably connected between the first rotating ring 32 and the semi-circular shell 1201.

[0042] In a preferred embodiment, the third extension bracket 5 includes a sixth double-grooved gear 16, with a seventh double-grooved gear 17 meshing on the side of the sixth double-grooved gear 16, a third triple-grooved gear 18 meshing above the seventh double-grooved gear 17, a second multi-grooved gear 19 meshing above the third triple-grooved gear 18, and a second head frame 20 meshing on the side of the second multi-grooved gear 19. During the assembly process, because all gear structures are identical to those of the sixth double-grooved gear 16, all gears have two insertion slots 1604. It has a connector 1605, so during use, the corresponding gear structure can be spliced ​​at any time and continuously extended upward. During the upward extension, it is fixed by the corresponding connector 1604 and connector 1605 to maintain the stability between the gear brackets. The side of the small gear 17 is meshed with the fourth three-groove gear 21, the upper side of the fourth three-groove gear 21 is meshed with the eighth double-groove gear 22, and the sides of the eighth double-groove gear 22 are respectively meshed with the ninth double-groove gear 23 and the third head assembly 24.

[0043] In a preferred embodiment, the third head assembly 24 includes a second rotating ring 33 and a toy bracket 2401. The toy bracket 2401 is connected to the side of the second rotating ring 33, and the second rotating ring 33 has the same structure as the first rotating ring 32. Since the first rotating ring 33 and the second rotating ring 32 have the same structure, their corresponding gear ring 3204 transmits power to the corresponding micro gear. The structure of the micro gear is specifically the micro gear 3202 in the sixth double-grooved gear 16. The power is transmitted outward through the micro gear to the corresponding locking post 3205 on the toy bracket 2401, so that the toy bracket 2401 can realize reciprocating motion. The toy bracket 2401 and the second rotating ring 33 are connected by the first connecting buckle 2402 and the second connecting buckle 2403, respectively.

[0044] In a preferred embodiment, the second extension bracket 4 includes a fourth double-grooved gear 13, a fifth double-grooved gear 14 meshing above the fourth double-grooved gear 13, and a head gear 15 meshing above the fifth double-grooved gear 14. Since the first large rotating gear 25 and the second large rotating gear 28 are also provided with insertion slots 1604 above the sixth double-grooved gear 16, when connecting the gear structure, the gears can be extended outward according to the corresponding insertion slots 1604.

[0045] In a preferred embodiment, two sets of parallel-meshing sixth pinions 26 mesh below the first large rotating gear 25, and two sets of parallel-meshing second pinions 29 mesh below the second large rotating gear 28. The sixth pinions 26 and the second pinions 29 have the same structure, and their corresponding rotating components 31 transmit kinetic energy to the first large rotating gear 25, which in turn transmits the kinetic energy to the second large rotating gear 28, and the energy is then transmitted through the sixth pinions meshed with the first and second large rotating gears 25. 26 and the second small rotating gear 29 drive the meshing gear to continue transmission. A connecting handle 2501 passes through the center of the first large rotating gear 25. An inner rotating ring 30 is installed on the side of the first large rotating gear 25 away from the connecting handle 2501. A gear is provided in the inner rotating ring 30 and meshes with the rotating component 31. A connecting strip 2701 is fixedly connected to the side of the push switch 27. A push bracket 3101 is engaged with the side of the connecting strip 2701. A connecting gear shaft 3102 is connected above the push bracket 3101. An electric motor 3103 is provided on the side of the connecting gear shaft 3102. When the push switch 27 is turned, the connecting bar 2701 causes the connecting gear shaft 3102 on the push bracket 3101 to separate from the gear in the opposite direction of the push, thus completing the power source switch. Since the push switch 27 can be pushed left and right, when the push switch 27 moves the connecting bar 2701, the connecting bar 2701 drives and moves the push bracket 3101 to move in the corresponding direction, thereby driving the push... When the connecting gear 3102 connected above the moving bracket 3101 moves in the corresponding direction of the push, and the connecting gear 3102 meshes with the power source in the direction of the push, the transmission chain structure between the connected gears is connected, so that the power is transmitted to the first large rotating gear 25, which rotates. Then, when the push switch 27 drives the connecting gear 3102 connected to the push bar 2701 to move to another position, the connecting gear 3102 is separated, and the transmission of the power source is disconnected.

[0046] In a preferred embodiment, the sixth double-grooved gear 16 includes a connecting housing 1601. Insertion slots 1604 are provided on both sides of the top end of the connecting housing 1601. A connector 1605 is provided below the connecting housing 1601. An external bracket 1606 is inserted into the end of the connector 1605. A first connecting tooth 1602 is rotatably connected to the side of the connecting housing 1601. A movable buckle 1603 is inserted between the connecting housing 1601 and the first connecting tooth 1602. The first triple-grooved gear 7 includes a first housing 701. Three sets of first pin holes 702 are provided at the top end of the first housing 701. The three sets of first pin holes 702 are equidistantly distributed along the first housing 701. A first tooth cover 703 is provided on the side of 701. A first connector 704 is inserted into the side of the first outer shell 701 away from the first tooth cover 703. The first multi-grooved gear 9 includes a second outer shell 901. A plurality of second pin holes 902 are provided at the top of the second outer shell 901. The plurality of second pin holes 902 are equidistantly distributed along the second outer shell 901. A second tooth cover 903 is provided on the side of the second outer shell 901. A second connector 904 is inserted into the side of the second outer shell 901 away from the second tooth cover 903. Except for the number and size of the grooves used for insertion, the sixth double-grooved gear 16, the first triple-grooved gear 7 and the first multi-grooved gear 9 have the same other necessary structural components.

[0047] The working process of this utility model is as follows: First, all the large gears used have the same structure, and the small gears also have the same structure. During the meshing process, the insertion slot 1604 provided above the first three-groove gear 7 connects with the insertion joints 1605 of other gears. During the connection process, the corresponding gears are connected, and during the connection process, the corresponding gears mesh with each other, thereby completing the fixing and connecting the transmission path. The first rotating ring 32 obtains the upward transmission force of the gear path. When the force drives its own gear ring 3204 to rotate, the first rotating ring 32 drives the toothed piece 1202 inside the semi-circular shell 1201 to rotate, thereby realizing the connection of the toy. The toothed piece 1202 is connected through the connector 1203, thereby completing the connection of the toothed piece 1202. The teeth of the micro gear 3202 mesh with the gear ring 3204. When the gear ring 3204 transmits power to the micro gear 3202, the locking pin 3205 connected to the micro gear 3202 drives the toothed piece 1202 to rotate.

[0048] During the assembly process, since all the gear structures are identical to the sixth double-grooved gear 16, each gear has two insertion slots 1604 and one insertion connector 1605. Therefore, during use, the corresponding gear structures can be assembled at any time and continuously extended upwards. During the upward extension, the gears are fixed by the corresponding insertion slots 1604 and insertion connectors 1605 to maintain the stability between the gear supports. Since the first rotating ring 33 and the second rotating ring 32 have the same structure, the corresponding gear ring 3204 transmits power to the corresponding micro gear. The structure of the micro gear is specifically the micro gear 3202 inside the sixth double-grooved gear 16. The power is then transmitted outwards through the micro gear to the locking pin 3205 on the corresponding toy support 2401, enabling the toy support 2401 to achieve reciprocating motion.

[0049] When the push switch 27 is turned, the connecting bar 2701 causes the connecting gear 3102 on the push bracket 3101 to separate from the gear in the opposite direction, thus switching the power source. Since the push switch 27 can be pushed left and right, when the push switch 27 moves the connecting bar 2701, the connecting bar 2701 moves the push bracket 3101 in the corresponding direction, thereby causing the connecting gear 3102 connected above the push bracket 3101 to move in the corresponding direction. When the connecting gear 3102 meshes with the power source in the direction it is pushed, the transmission chain structure between the connected gears is connected, thus transmitting power to the first large rotating gear 25, causing it to rotate. When the push switch 27 moves the connecting gear 3102 connected to the push bar 2701 to another position, the connecting gear 3102 separates, and the power source transmission is disconnected. The above is the working principle of this gear transmission educational toy.
