[0013] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0014] Please refer to Figure 1 , Figure 2 and Figure 3 A portable cycling platform according to an embodiment of the present invention comprises a bracket 1, two triangular plates 2, a driving wheel, a first transmission assembly and a second transmission assembly. The bracket 1 is composed of two rectangular hollow steel materials horizontally. The two triangular plates 2 are detachably arranged in parallel on the bracket 1. The triangular plates 2 are vertically arranged in the middle of the bracket 1. A first transmission assembly is arranged on the outer side of the triangular plates 2. The first transmission assembly and the second transmission assembly are connected by a belt. The first transmission assembly comprises a first fixed rotating wheel 3 and a second fixed rotating wheel 4. The axis of the first fixed rotating wheel 3 is rotatably arranged at the side center of the triangular plate 2. The second fixed rotating wheel 4 is arranged obliquely above the first fixed rotating wheel 3. The second transmission assembly is arranged at the top of the triangular plate 2. The second transmission assembly comprises a first flywheel 5 and a second flywheel 6. The axis of the first flywheel 5 is rotatably arranged at the top of the triangular plate 2. The axis of the second flywheel 6 is rotatably arranged between the two triangular plates 2. The axis of the second flywheel 6 is fixedly connected to the axis of the first fixed rotating wheel 3.

[0015] By arranging the first transmission assembly and the second transmission assembly on the triangular plate 2, the space occupied by the conventional cycling platform bracket is greatly reduced. The entire cycling platform is fixed by the bracket 1 and the triangular plate 2. The first transmission assembly and the second transmission assembly are used to realize the riding function of the cycling platform, which is convenient for users to carry.

[0016] Preferably, a multi-stage speed regulating gear set 7 is provided on the side of the first flywheel 5, and the axis of the multi-stage speed regulating gear set 7 is fixedly connected to the axis of the first flywheel 5. The multi-stage speed regulating gear set 7 enables the user to perform multi-stage speed regulation and provide various speeds required by the user.

[0017] Preferably, the second fixed wheel 4 is arranged on the triangle plate 2, and a limiting groove 8 is arranged on the triangle plate 2. The second fixed wheel 4 is a bearing wheel, and the axis of the second fixed wheel 4 can be adjusted and fixed in the limiting groove 8. The length of the limiting groove 8 is greater than the axis diameter of the second fixed wheel 4. The second fixed wheel 4 is arranged in the limiting groove 8, and the position in the limiting groove 8 can be adjusted, which can effectively adjust the tightness of the entire belt to ensure that the belt will not slip during the entire riding process.

[0018] Preferably, the second fixed wheel 4 is located on the outside of the belt, the axis of the second fixed wheel 4 is located between the common tangent of the first flywheel 5 and the first fixed wheel 3 and the central axis of the riding platform, and the axis position is located between the common tangent of the first flywheel 5 and the first fixed wheel 3 and the central axis of the riding platform, so that the belt is pushed inward by the second fixed wheel 4, the contact area between the belt and the first flywheel 5 is larger, the friction is stronger, and the belt slippage is avoided.

[0019] Preferably, the lowest end of the second flywheel 6 is higher than the bottom end of the triangle plate 2 to ensure that the second flywheel 6 does not rub against the ground during movement, thereby preventing damage.

[0020] As described above, when the utility model is actually used, the user disassembles the rear wheel of the bicycle and installs the chain on the multi-stage speed regulating gear set 7 to carry out cycling training. The entire cycling platform is fixed by the bottom bracket 1 and the triangular plate 2, which greatly reduces the space occupied by the external bracket and is convenient for the user to store.

[0021] The present invention has been described by the above-mentioned relevant embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any changes and modifications made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
