[0019] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0020] See Figures 1-5 , a pedal connection structure of a rehabilitation device, including a vehicle frame 10 and a pedal 20, a quick-release assembly 30 is installed on the vehicle frame 10, and the pedal 20 is connected to the quick-release assembly 30;

[0021] The quick-release assembly 30 at least includes a first plugging member 310 connected to the vehicle frame 10 and a second plugging member 320 connected to the pedal 20;

[0022] The first plugging member 310 and the second plugging member 320 are plugged and cooperated;

[0023] The quick-release component 30 further includes a locking component 40 for locking the first plug-in component 310 and the second plug-in component 320 to each other.

[0024] Based on the above embodiments, the utility model mates the first plug-in component with the second plug-in component, and then locks them under the action of the locking component. When disassembling, only need to release the lock of the locking component, then the pedal can be moved to separate the second plug-in component from the first plug-in component, and the disassembly and separation can be completed.

[0025] See Figure 4 , a plug-in block 340 is provided on the first plug-in component 310, a plug-in slot 330 is provided on the second plug-in component 320, and the plug-in block 340 is in plug-in fit with the plug-in slot 330.
