DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0025] like Figures 1 to 5 As shown, the utility model provides a snap-fit ​​assembly type gear box, comprising a box body 1 and a gear module 2 arranged in the box body 1, wherein the box body 1 comprises a first shell 11 and a second shell 12, a plurality of snap-fit ​​structures 3 are arranged between the first shell 11 and the second shell 12, and the gear module 2 is located between the first shell 11 and the second shell 12;

[0026] The buckle structure 3 includes a buckle slot 4, a buckle body 5 and a pushing piece 6. The buckle slot 4 and the pushing piece 6 are spaced apart in the first shell 11, and the buckle body 5 is arranged in the second shell 12. The buckle body 5 is used to be inserted between the buckle slot 4 and the pushing piece 6, and the pushing piece 6 is used to force the buckle body 5 to be inserted into the buckle slot 4.

[0027] In actual use, the number of the buckle structures 3 is four, and the four buckle structures 3 are grouped in pairs and are respectively arranged on both sides of the box body 1. When producing the utility model, it is only necessary to install the gear module 2 to the first housing 11 / the second housing 12, and then align the first housing 11 and the second housing 12 with each other and press them together. During the pressing process, the buckle body 5 will be inserted into the gap between the buckle groove 4 and the push piece 6, and when the buckle body 5 is facing the buckle groove 4, the push piece 6 forces the buckle body 5 to be inserted into the buckle groove 4, so as to realize the buckle connection between the first housing 11 and the second housing 12.

[0028] The utility model optimizes the structure between the first shell 11 and the second shell 12 so that the step of locking screws is omitted in the assembly process, which is beneficial to improving efficiency and reducing costs; and after the assembly is completed, since the push piece 6 always keeps the buckle body 5 forced to insert into the buckle groove 4, the stability of the assembly can also be guaranteed.

[0029] In this embodiment, the buckle body 5 has a sloping surface 52, which is used to align with the bottom of the buckle groove 4 and guide the buckle groove 4 to move along the sloping surface 52 until the buckle body 5 is inserted into the buckle groove 4. That is, in order to ensure that the buckle body 5 is inserted into the buckle groove 4, the thickness of the buckle body 5 of the utility model must be greater than the gap width between the buckle groove 4 and the push piece 6. In addition, the first shell 11 and the second shell 12 of the utility model have a certain deformation amount. Therefore, in the assembly process, in order to reduce the damage of the buckle groove 4 or the buckle body 5 caused by rigid collision, the utility model is provided with a sloping surface 52, so that the bottom of the buckle groove 4 is sloping along the sloping surface 52 to increase the gap width, and the buckle body 5 can smoothly enter the gap, and complete the sloping surface after the buckle body 5 is facing the buckle groove 4 and is smoothly inserted into the buckle groove 4. In addition, the continuous resistance of the push piece 6 ensures the buckling effect between the two.

[0030] Specifically, a corresponding inclined surface structure 41 may be provided at one end of the buckle slot 4 away from the first shell 11 , so as to cooperate with the giving way inclined surface 52 to achieve a smoother assembly effect.

[0031] In this embodiment, the pushing member 6 includes a mounting portion 61 and a pushing portion 62 . The mounting portion 61 is arranged to be inclined relative to the first housing 11 , and the pushing portion 62 is arranged at the bottom of the mounting portion 61 close to one side of the buckle groove 4 .

[0032] The pushing member 6 abuts against the buckle body 5 to force the buckle body 5 to be inserted into the buckle slot 4 and continuously applies the forcing force to ensure the stability of the buckle slot 4 .

[0033] As another implementation of this embodiment: a connecting portion 51 is provided between the buckle body 5 and the second shell 12 , and the buckle body 5 is provided on a side of the connecting portion 51 facing the buckle groove 4 ; the buckle body 5 is provided on the second shell 12 at an angle relative to the second shell 12 .

[0034] That is, the utility model only needs to ensure that the buckle body 5 and the push piece 6 are relatively inclined to ensure reliable interference between the two, so that the push piece 6 always has a stress forcing the buckle body 5 to be inserted into the buckle groove 4.

[0035] In this embodiment, the housing 1 is provided with a mounting groove 13, and a stopper 14 is movably provided in the mounting groove 13. The stopper 14 is used to abut against the gear module 2 to force the gear module 2 to stop rotating. The gear module 2 is preferably provided with a locking plate 21. When the gear module 2 needs to be stopped from rotating, it is only necessary to press the stopper 14 so that the designated part abuts against the side wall of the locking plate 21. The friction between the two can decelerate the gear module 2 and achieve the effect of stopping.

[0036] In this embodiment, a lever member 15 and a transmission member 16 are rotatably arranged on the outer side of the box body 1. The lever member 15 has a control end 151 and a follower end 152. The gear module 2 drives and connects the transmission member 16. A transmission disc 161 is arranged at one end of the transmission member 16 away from the box body 1. An inclined portion 162 is arranged on the outer side of the bottom of the transmission disc 161. The inclined portion 162 is used to contact the control end 151 and control the lever member 15 to tilt up through the control end 151.

[0037] The length of the follower end 152 is greater than the length of the control end 151 .

[0038] That is, under normal conditions, the follower end 152 remains in a sunken state due to its long length, while the control end 151 tilts up due to the sinking of the follower end 152; at this time, since the transmission member 16 rotates with the gear module 2, the inclined portion 162 of the transmission member 16 rotates, and the control end 151 can be sunk and the follower end 152 can be driven to tilt up through the change of the contact position between the inclined portion 162 and the control end 151; when the inclined portion 162 does not conflict with the control end 151, the follower end 152 is restored to a sunken state due to the force arm of the follower end 152 being greater than the force arm of the control end 151... In this way, the follower end 152 of the lever member 15 can periodically repeat the tilting and sinking actions as long as the gear module 2 continues to rotate, making the actions of the utility model more diverse and can be flexibly used in the action control of toys.

[0039] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
