[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figures 1-4 As shown, the toy track base structure in this example includes a base 2 and a base 1 for supporting the track. The base 1 includes legs 100 and a crossbeam 101. Two parallel legs 100 are connected by a horizontally arranged crossbeam 101. The first and last ends of the crossbeam are connected to the legs respectively. Preferably, the legs and crossbeam are integrally injection molded. Figure 1 The base 1 shown is H-shaped overall.

[0025] In this example, the bottom of the support leg 100 is formed with a groove 20, and the side wall of the groove 20 is formed with a notch 21. For example, the side wall of the groove 20 facing the two support legs is formed with a notch 21. The top surface of the base 2 is formed with a protrusion 23 that fits into the groove 20. The protrusion 23 is interference-fitted with the groove wall of the groove 20. During assembly, the protrusion at the corresponding base is inserted into the bottom groove of the corresponding support leg, so that the support leg of the base and the base are fixed together. The increase of the notch makes it easier to expand the groove of the groove, which facilitates the insertion of the protrusion and helps to reduce the phenomenon of cracking of the groove wall.

[0026] For protrusions, such as common rectangular or cylindrical protrusions, the preferred choice is... Figure 3 As shown in the structure, the top surface of the plate-shaped body of the base 2 has an outwardly protruding protrusion 23. The protrusion 23 includes a horizontal plate 231 and a vertical plate 230. The horizontal plates 231 are formed at intervals on both sides of the vertical plate 230. This configuration can maintain the required structural strength while reducing weight. In this example, a slot 24 can also be formed around the protrusion 23. The slot is used to insert and cooperate with the groove wall of the first groove. When the protrusion and the first groove are engaged and fixed, the groove wall of the first groove is simultaneously inserted into the slot, which helps to improve the stability of the structure.

[0027] Preferably, an insert plate 22 is formed at the base 2 corresponding to notch 21. When the protrusion and the groove are engaged and connected, the insert plate 22 is simultaneously inserted into notch 21, and the side of the insert plate is fitted with the cavity wall of notch 21 with a clearance, which helps to improve aesthetics. To reduce weight, in this example, a groove for weight reduction is formed on the bottom surface of the base 2, and reinforcing ribs 25 and 26 are formed in the groove cavity to improve structural strength. Reinforcing rib 25 is annular, and reinforcing rib 26 is formed around reinforcing rib 25 at intervals. The end of reinforcing rib 26 is connected to the groove wall. In addition, weight-reducing grooves can also be formed on the opposite sides of the two legs to help reduce weight.

[0028] In this example, the top of the support leg 100 is formed with a groove 102 for fitting and connection, and the side wall of the groove 102 is formed with a notch 103, such as... Figure 1As shown, notches 103 are formed at intervals on the side walls of the grooves 102 opposite to each other on the two legs 100. When in use, if the track post is inserted into the groove, the presence of notches 103 also makes it easy for the groove opening of the groove to expand, which facilitates the fitting and connection with the track post.

[0029] To improve structural stability, in this example, reinforcing plates 105 are formed between the sides of the two legs 100 facing each other and the crossbeam 101. The ends of the reinforcing plates 105 are connected to the sides of the legs 100, and the bottom surface of the reinforcing plates 105 is connected to the top surface of the crossbeam 101. Notches 103 are formed at intervals on the sides of the two legs 100 facing away from each other, and protruding ribs 104 are formed on the sides between the notches 103. The addition of reinforcing plates helps to improve the stability of the structure, and the addition of ribs helps to improve the stability of the connection.

[0030] To improve the stability of the connection with the track, in this example, a connecting hole 107 is formed longitudinally in the middle of the crossbeam 101 to facilitate docking with other components of the track, such as fastening with bolts.

[0031] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
