The wheel base 30 is temporarily positioned. It is worth mentioning that, please refer to "Figure 5" and "Figure 6" at the same time. This is a partially enlarged perspective view of the implementation of the "Figure 2" and the implementation of the "Figure 4". As shown in the figure, the end of the guide block 31 of the present invention extends to provide a driving column 34 for driving a buffer 60 disposed in the sliding rail 50, so that the sliding rail 50 can be driven. This buffer 60 operates.

It can be seen from the above-mentioned preferred embodiments and the detailed technical content that, since the pulley structure 1 is simple in the present invention, the production cost is low, and the market competitiveness can be improved to meet the needs of the industry; and the thickness of the pulley structure 1 can be reduced to less than 10 mm. Therefore, the thickness of the sliding door 40 can be effectively reduced after assembly, so that the outer shape is more beautiful. The pulley structure has the elastic member 24 elastically supported, so that it can be easily retracted into the sliding rail 50 before being assembled by the positioning screw. 122 is fixed, and can be effectively prevented from derailing after being fixed; and the pulley structure 1 also has a driving column 34 on both sides thereof, so that the buffer 60 disposed in the sliding rail 50 can be driven to meet the needs of the consumer. .
