Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model discloses a tire inclination adjustment device for a model car, comprising a connecting rod 10, a connecting shell 20 welded at one end of the connecting rod 10, a wheel axle base 30 rotatably connected to the front and rear inner walls thereof is arranged in the connecting shell 20, the front and rear inner walls of the wheel axle base 30 are both provided with receiving grooves 40, gears 50 are welded in the two receiving grooves 40, a toothed roller 60 rotatably connected to the front and rear inner walls thereof is arranged in the connecting shell 20, the diameter of the toothed roller 60 is smaller than the diameter of the gear 50, the toothed roller 60 is meshedly connected with the two gears 50 at the same time, an indicator plate 70 fixedly connected to the toothed roller 60 is arranged on the front side of the connecting shell 20, a plurality of circumferentially distributed indicator mounting holes 80 are arranged on the front side of the connecting shell 20, three first bolts 90 are installed on the front side of the indicator plate 70, the three first bolts 90 are respectively threadedly connected with the three indicator mounting holes 80, and a stabilizing mechanism is arranged on the upper and lower inner walls of the connecting shell 20.

[0022] Specifically, the indicating mounting hole 80 is composed of a threaded interface and an indicating groove, and the diameter of the indicating disk 70 is greater than the diameter of the gear roller 60 .

[0023] In this embodiment, the indicating mounting hole 80 not only serves as a scale line, but can also cooperate with the first bolt 90 to realize the fixed installation of the indicating plate 70. The diameter of the indicating plate 70 is larger than the diameter of the gear roller 60, and the number of indicating mounting holes 80 can be increased, thereby increasing the inclination adjustment accuracy.

[0024] Specifically, the axle base 30 is composed of a block and a disc, the block and the disc are connected as one body, and four mounting holes are provided on the side wall of the disc.

[0025] In this embodiment, the shape and structure of the axle base 30 are disclosed.

[0026] Specifically, the stabilizing mechanism includes a pair of limiting slide grooves 100, and the two limiting slide grooves 100 are respectively arranged on the upper and lower inner walls of the connecting shell 20. The two limiting slide grooves 100 are each provided with a slide seat 200 connected thereto for upward and downward sliding. The sides of the upper and lower slide seats 200 close to each other are integrally connected with a limiting strip 300. The upper and lower inner walls of the connecting shell 20 are each provided with a screw rod 400 rotatably connected thereto. The ends of the upper and lower screw rods 400 away from each other are integrally connected with a bolt head 500, and the slide seat 200 is threadedly connected to the screw rod 400.

[0027] In this embodiment, after the inclination angle of the axle base 30 is adjusted, the bolt head 500 can be rotated forward to drive the screw 400 to rotate. At this time, the slide seat 200 with the limiting strip 300 will move along the limiting slide groove 100 close to the axle base 30, and make the limiting strip 300 fit on its upper and lower outer walls, which can increase the stability of the axle base 30 after the inclination angle is adjusted.

[0028] Specifically, a pair of threaded holes 600 are respectively formed on the top surfaces of the two slide seats 200 , and a pair of round holes 700 are respectively formed on the upper and lower surfaces of the connecting shell 20 . A second bolt 800 threadably connected to the threaded hole 600 is inserted into each round hole 700 .

[0029] In this embodiment, the strength of the stabilizing mechanism can be further enhanced, which can play an auxiliary role and effectively ensure the stability of the tire of the car model after the inclination angle is adjusted.

[0030] Specifically, long grooves 900 are formed on both the upper and lower surfaces of the axle base 30 , and the limiting strip 300 is attached to the long grooves 900 .

[0031] In this embodiment, the limiting strip 300 can be placed on the long groove 900 to stabilize the wheel axle base 30 .

[0032] The working principle and use process of the utility model are as follows: rotating the indicator plate 70 can directly drive the gear roller 60 to rotate, the gear roller 60 drives the gear 50 to rotate, and the gear 50 drives the axle base 30 to swing. Since the diameter of the gear 50 is smaller than the diameter of the gear 50, when the indicator plate 70 is rotated at a large angle, the axle base 30 only swings slightly, and the inclination adjustment accuracy is high. After the inclination adjustment is completed, the first bolt 90 is rotated forward to be threadedly fixed with the corresponding indicator mounting hole 80, which can achieve preliminary fixation, and then the first bolt 90 is rotated forward to be threadedly fixed with the corresponding indicator mounting hole 80, so as to achieve initial ... The upper and lower bolt heads 500 and the screw rod 400 rotate forward, which can drive the slide seat 200 to move along the limiting slide groove 100 close to the wheel axle base 30 until the limiting long strip 300 is against the long groove 900, and finally the second bolt 800 is rotated forward, and the second bolt 800 is threadedly connected with the threaded hole 600. At the same time, the head of the second bolt 800 is tightly fitted on the upper and lower outer walls of the connecting shell 20, which can further improve the stability of the wheel axle base 30 after the inclination angle is adjusted, thereby ensuring the stability of the car model tire after the inclination angle is adjusted.
