[0021] Embodiment 1: A safety roller for extreme sports with anti-debonding, see Figure 1 and Figure 2 , including a wheel hub 1 and a rim 11 covering the wheel hub 1, wherein the wheel hub 1 and the rim 11 are wrapped with a buffer 12 for reducing sliding vibration and impact, and a limiting component 2 is arranged between the wheel hub 1 and the rim 11, and the limiting component 2 is used to limit and fix the connection between the wheel hub 1 and the rim 11.

[0022] The buffer 12 is sleeved on the wheel hub 1, and then the wheel rim 11 is covered on the wheel hub 1, so that the wheel hub 1 and the wheel rim 11 completely wrap the buffer 12, and the limiting component 2 is used to limit and fix the connection between the wheel hub 1 and the wheel rim 11, so that when the roller moves, the wheel hub 1 and the wheel rim 11 can be prevented from being separated, and the setting and installation of the buffer 12 are further limited, the connection between them is strengthened, and the safety of the roller is improved.

[0023] Especially in extreme sports, most rollers on the market are made of composite elastic materials to improve comfort. The buffer 12 can reduce sliding vibration and impact. However, due to the independent setting of the buffer 12, the contact between the wheel hub 1 and the wheel rim 11 is greatly reduced.

[0024] To this end, the present embodiment improves the structure of the buffer 12 by configuring the buffer 12 into a flat annular shape, so that it can be easily mounted on the wheel hub 1 while minimizing the abutment between the wheel hub 1 and the wheel rim 11 while ensuring that sliding vibration and impact are reduced.

[0025] On the other hand, a limiting component 2 is provided, and the limiting component 2 includes a first limiting groove 21 opened in the wheel hub 1 and an accommodating groove 22 opened in the wheel rim 11, the first limiting groove 21 and the accommodating groove 22 constitute an accommodating space for embedding the buffer 12, and a plurality of through holes 23 are distributed on the buffer 12. The wheel rim 11 is provided with a connecting column 24 in the accommodating groove 22, and the connecting column 24 is inserted into the through hole 23, so that the wheel rim 11 and the buffer 12 are fixedly connected.

[0026] The wheel rim 11 is cast, and for this purpose, after the wheel hub 1 and the buffer 12 are installed, they are placed in a mold to cast the wheel rim 11. At this time, the buffer 12 is located in the accommodating groove 22 and fixed therein, and the first limiting groove 21 directly contacts the buffer 12. Due to the setting of the first limiting groove 21, the contact area between the wheel rim 11 and the wheel hub 1 is further improved. In addition, since a plurality of through holes 23 are distributed on the buffer 12, the cast-molded wheel rim 11 will pass through the through holes 23 to form connecting columns 24 during casting, thereby completing the fixed connection between the buffer 12 and the wheel rim 11, reinforcing the connection between the buffer 12 and the wheel rim 11, and promoting the buffer 12 to become one with the wheel rim 11, thereby forming a stable connection between the wheel rim 11 and the wheel hub 1.

[0027] Specifically, the wheel rim 11 is made of a transparent material, and the buffer member 12 is covered with colors, so as to enhance the ornamental value of the roller.

[0028] Specifically, the wheel hub 1 is made of plastic or metal.

[0029] Embodiment 2: A safety roller for extreme sports with anti-debonding, see Figure 3 The difference between this embodiment and the first embodiment is that the limiting assembly 2 includes a second limiting groove 25 opened in the wheel hub 1 and an accommodating cavity 26 opened in the wheel rim 11, the buffer member 12 is embedded in the accommodating cavity 26, and the buffer member 12 forms a protrusion 27 in the wheel rim 11, and the protrusion 27 is inserted into the second limiting groove 25 to form a stable connection.

[0030] Since the wheel rim 11 is cast, after the wheel hub 1 and the buffer 12 are installed, they are put into a mold to cast the wheel rim 11. At this time, the buffer 12 and the wheel hub 1 are separated so that the wheel rim 11 completely wraps the buffer 12, and the buffer 12 is embedded in the accommodating inner cavity 26. The buffer 12 forms a protrusion 27 in the wheel rim 11, and the protrusion 27 is inserted into the second limiting groove 25 to form a stable connection.

[0031] The rest of this embodiment is the same as the first embodiment. The features not explained in this embodiment are all based on the explanations in the first embodiment and will not be described in detail here.

[0032] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
