Skateboards have become a popular and fashionable sports equipment, with advantages such as small packaging and transportation volume, light weight, easy portability, and a wide age range of applicability, making them particularly popular among skateboarding enthusiasts. However, the four-wheeled skateboards currently on the market have the following shortcomings during use: the movements are not precise enough during rapid, small-angle turns, and friction noise is generated due to incompatibility or improper assembly of the springs with the base and frame.
[0003] Therefore, there is an urgent need for a skateboard bracket base wheel assembly that can provide more precise movements and quiet operation during use. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a skateboard bracket base wheel assembly to solve the problems mentioned in the background art.

[0006] A skateboard bracket base wheel assembly includes a base and a bracket adapted to the base. Both the base and the bracket have cavities. A spring is disposed between the cavity of the base and the cavity of the bracket. The cavity of the base has a tapered groove A for assembling with the spring, and the cavity of the bracket has a tapered groove B for assembling with the spring. The end of the spring that contacts the tapered groove A has a tapered cut surface A, and the end of the spring that contacts the tapered groove B has a tapered cut surface B. The spring is tightly assembled into the tapered groove A of the base through the tapered cut surface A, and the spring is tightly assembled into the tapered groove B of the bracket through the tapered cut surface B.
[0007] Furthermore, the end of the spring that contacts the tapered groove A is provided with two tapered surfaces A, which are mirror images of each other. The end of the spring that contacts the tapered groove B is provided with two tapered surfaces B, which are mirror images of each other.
[0008] Furthermore, it also includes a connecting shaft, an upper bearing, a lower bearing, a washer, and a nut; the connecting shaft passes through the base, the upper bearing, the bracket, the lower bearing, and the washer in sequence, forming a bracket that can rotate radially. When the spring is compressed and released, the spring releases its elastic force to rotate the bracket back to its original position.
[0009] The upper bearing is located on a boss inside the bracket, the lower bearing is located in a groove at the bottom of the bracket, the gasket has a raised step, the raised step mates with the inner hole of the lower bearing, the inner hole of the gasket mates with the outer diameter of the connecting shaft, and the nut is connected to the end of the connecting shaft.
[0010] Furthermore, the connecting rod on the bracket is connected to a wheel, and the wheel is connected to the connecting rod on the bracket via a wheel nut.
[0011] Furthermore, the top of the base is provided with several screw holes, and the base is fixedly connected to the bottom surface of the skateboard pedal by setting screws.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] A skateboard bracket base wheel assembly is provided, including a base and a bracket adapted to the base. Both the base and the bracket have cavities. A spring is disposed between the base cavity and the bracket cavity. The base cavity has a tapered groove A for assembling the spring, and the bracket cavity has a tapered groove B for assembling the spring. The end of the spring that contacts the tapered groove A has a tapered cut surface A, and the end of the spring that contacts the tapered groove B has a tapered cut surface B. The spring is tightly fitted into the tapered groove A of the base through the tapered cut surface A, and into the tapered groove B of the bracket through the tapered cut surface B. This design ensures a tight connection between the spring, the base, and the bracket. With prolonged use, the tapered grooves of the bracket and base widen under the friction and compression of the spring, and the connection between the spring and the tapered groove becomes more compact under the axial pressure of the spring. This results in more precise movement and quiet operation during use. This skateboard bracket base wheel assembly features a simple structure, smooth ride, flexible steering, and reliable connection, making it particularly suitable for skateboards, land-riding boards, scooter frames, and related products.
