Description

Technical Field

[0001] This utility model belongs to the field of toys, specifically relating to a toy train track connector structure that can be spliced ​​and changed tracks. Background Technology

[0002] In toy train track systems, traditional track connectors often have many limitations. On the one hand, it is difficult to flexibly adjust the track height, and when it is necessary to build multi-layer track scenes or adapt to different terrain simulations, there is a lack of convenient height adjustment methods. On the other hand, the expandability and adaptability of the track after splicing are poor, making it difficult to quickly change the track layout according to play needs. Moreover, the linkage between the components is insufficient, and problems such as inconsistent track heights on both sides and unstable splicing are prone to occur during the adjustment process, affecting the smoothness of the toy train's operation and the play experience. To solve the above problems, a toy train track connector structure that can be spliced ​​and changed tracks is proposed. Utility Model Content

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Please see Figure 1-4This utility model provides a toy train track connector structure that can be spliced ​​and changed tracks, including a telescopic base 1; The telescopic base 1 includes a bearing sleeve 11, a telescopic sleeve 12, and a frame 13. The bearing sleeve 11 provides a central installation base for the whole. The frame 13 can slide relative to the bearing sleeve 11 on the outer wall of the telescopic sleeve 12, thereby driving the upper lifting component 2 to change the spacing. In this way, when splicing tracks of different lengths or tracks that need to be changed, the positions of the two lifting components 2 can be flexibly adjusted so that the pins on the track can be smoothly inserted into the lifting components 2. Two lifting components 2 are respectively installed on the top of the two sleeves 13 and extend into the interior of the telescopic base 1; The fixing screw 3 is threaded on the outer wall of one of the lifting components 2; The elastic connector 4 is disposed in the middle of the inner cavity of the bearing sleeve 11; Two linkage components 5 are respectively installed inside the two sleeves 13 and connected to both sides of the elastic connector 4; The lifting component 2 is used to adjust the load height on the train track. The telescopic base 1 is used to enable the two lifting components 2 to be extended or retracted, so that the pins on the track can be inserted into them. The elastic connector 4 is used to maintain the transmission state between the two linkage components 5 when the two lifting components 2 are extended or retracted. The linkage component 5 is used to drive the lifting component 2 on the other side to be adjusted synchronously when one lifting component 2 is adjusted.

[0013] Specifically, refer to Figure 2-3 The lifting component 2 includes a column 21, a threaded rod 22, a lifting block 23, a pin hole 24, and a gear 25. The column 21 serves as the main support for the lifting structure. The threaded rod 22 can rotate within the column 21 and the sleeve 13, driving the lifting block 23 to rise and fall along the column 21 via threaded transmission, thereby adjusting the track bearing height to meet the needs of building tracks for different terrains such as slopes and downhill sections. The pin hole 24 is used to cooperate with the track pin to achieve track splicing and fixing. The gear 25 cooperates with the linkage 5 to transmit lifting adjustment power. The fixing screw 3 locks the rotation state of the threaded rod 22 by pressing against it, thereby fixing the height of the lifting block 23.

[0014] Specifically, refer to Figure 3-4The elastic connector 4 comprises a support base 41, a sleeve 42, a cross shaft 43, and a spring 44. The support base 41 is fixed inside the bearing sleeve 11, providing rotational support for the sleeve 42. The sleeve 42 can rotate relative to the support base 41, and the cross shaft 43 can slide inside the sleeve 42. The spring 44 provides elastic force, keeping the cross shaft 43 connected within the sleeve 42. When the sleeve 13 in the telescopic base 1 expands or contracts, the cross shaft 43 can slide adaptively while maintaining the transmission connection with the linkage 5. This ensures that the elastic connector 4 can still transmit power when the distance between the two lifting components 2 changes, maintaining the transmission state between the two linkage components 5. This solves the problem of transmission failure that may be caused by changes in distance, making the linkage of components more stable.

[0015] Specifically, refer to Figure 3 The linkage 5 consists of a bearing 51, a rotating rod 52, and a second gear 53. The bearing 51 is fixed inside the sleeve 13, providing rotational support for the rotating rod 52. One end of the rotating rod 52 meshes with the first gear 25 of the lifting component 2 through the second gear 53, and the other end is connected to the cross shaft 43 of the elastic connector 4. When the threaded rod 22 of one side of the lifting component 2 rotates to adjust the lifting, the rotating rod 52 is driven to rotate through the first gear 25 and the second gear 53. The power is then transmitted through the elastic connector 4 to make the rotating rod 52 of the other side rotate synchronously, thereby driving the threaded rod 22 of the other side of the lifting component 2 to rotate, realizing synchronous lifting adjustment of the two lifting components 2. This ensures that the height of both sides of the track changes synchronously, avoiding track tilt from affecting the operation of the toy train. Compared with the non-linkage design, it improves the consistency and stability of track height adjustment.

[0016] Working principle When the track needs to be spliced, push the telescopic sleeve 12 to slide relative to the bearing sleeve 11, which will drive the sleeve frame 13 and the lifting component 2 to change the distance, so that the track pin is aligned with the pin hole 24 of the lifting component 2, and insert the pin to complete the initial splicing of the track; the cross shaft 43 of the elastic connector 4 can slide in the sleeve 42 with the change of the distance of the sleeve frame 13, maintain the connection with the linkage 5, and prepare for subsequent synchronous adjustment. When adjusting the track height, manually rotate one threaded rod 22. The rotation of threaded rod 22 causes the lifting block 23 to rise and fall along the column 21. At the same time, the first gear 25 at the bottom of threaded rod 22 rotates, which drives the rotating rod 52 to rotate through the second gear 53. The rotating rod 52 transmits power through the cross shaft 43 and the sleeve 42, causing the rotating rod 52 on the other side to rotate synchronously. This, in turn, drives the threaded rod 22 of the lifting component 2 on the other side to rotate, realizing the synchronous rise and fall of the lifting blocks 23 on both sides and adjusting the overall height of the track. After adjustment, rotate the fixing screw 3 so that one end of it presses against the threaded rod 22, locking the rotation of the threaded rod 22 and fixing the track height. During the expansion or contraction of the telescopic base 1, the spring 44 of the elastic connector 4 pushes the cross shaft 43 to slide within the sleeve 42, adapting to changes in the spacing of the sleeve 13. At the same time, it maintains the connection between the cross shaft 43 and the rotating rod 52, ensuring that the transmission relationship of the linkage 5 is not interrupted. This allows the lifting parts 2 on both sides to still achieve synchronous lifting and lowering adjustment through the linkage 5 and the elastic connector 4 after the spacing changes, ensuring the synchronicity and stability of the track height adjustment, and making the toy train run more smoothly in scenarios such as changing tracks and climbing slopes.
