AI Technical Summary
The existing foot pedal resistance band has an unstable connection between the left and right pedals via an elastic buckle, making it difficult for users to control their strength and causing them to easily separate, thus affecting the training effect.
It adopts a pin and slot structure, with the pin and slot moving in opposite directions. The left and right pedals are stably connected by the cooperation of the pin and the hole. A transverse slide and a V-shaped spring are set to ensure the stable movement of the pin. The vertical engagement of the locking block and the slot ensures stability. Flexible parts are set on the pedals to prevent them from falling off.
It achieves a stable connection for the foot pedal resistance band, avoids misoperation, provides multiple exercise modes, and enhances the user's exercise choices and structural stability.

Abstract
Claims
1. A foot-pedal pulley comprising a handle and a foot-pedal, the foot-pedal and the handle being connected by a springy cord; characterized in that: The pedals include a detachably connected left pedal and a right pedal. An elastic cord is provided between the left pedal and the handle, and an elastic cord is also provided between the right pedal and the handle. The elastic cords of the left pedal and the right pedal support the left pedal and the right pedal respectively. The left foot pedal is provided with a locking block, and the right foot pedal is provided with a locking groove that cooperates with the locking block. When the locking block is locked in the locking groove, the left foot pedal and the right foot pedal are connected. It also includes a latch, which is set on the pedals and connects the left and right pedals that are locked together. The movement direction of the latch is offset from the movement direction of the locking block and the locking groove.
2. The foot-pedal exerciser according to claim 1, wherein: The pin can enter and exit the interior of the left pedal, and the right pedal is provided with a hole that mates with the pin. The elastic element provides force to extend the pin out of the left pedal and into the hole; by driving the pin and moving it away from the hole, the left pedal and the right pedal can be separated.
3. The foot-pedal exerciser according to claim 2, wherein: The pin is provided with a pushing part, which is exposed for the user to push.
4. The foot-pedal exerciser according to claim 2 or 3, wherein: The left foot pedal is provided with a transverse sliding groove, and the pin moves along the transverse sliding groove; the elastic element is a V-shaped spring sheet, which is compressed in the transverse sliding groove.
5. The foot-pedal exerciser according to claim 4, wherein: The left pedal is equipped with at least two locking blocks; the locking blocks simultaneously engage with the corresponding right pedal's locking slot.
6. The foot pedal resistance device according to claim 5, characterized in that: The pin is located between the locking blocks, and the locking blocks cover the protruding part of the pin; the hole is located on the end face between the locking slots; the driving pin retracts, so that the locking slots and locking blocks can engage; when the locking slots and locking blocks engage to the designated position, the pin fixes them in place.
7. The foot-pedal exerciser according to claim 1 or 2 or 3 or 5 or 6, wherein: The left pedal has a horizontally arranged locking block, and the right pedal has a horizontally arranged locking groove corresponding to the locking block. The direction in which the locking block enters the locking groove is perpendicular to the connection direction of the left and right pedals. The locking groove is a dovetail groove.
8. The foot-pedal exerciser as set forth in claim 6, wherein: The slot does not pass through the right foot pedal. One end of the slot is an inlet, and the other end has a baffle. The block enters from the inlet and can abut against the baffle.
9. The foot-pedal exerciser according to claim 1 or 2 or 3 or 5 or 6 or 8, wherein: The left foot pedal includes a left fixed shaft and a left foot pedal, with the left foot pedal sleeved on the outside of the left fixed shaft; a flexible element is provided above the left foot pedal to prevent the user's foot from detaching from the left foot pedal. The right foot pedal includes a right fixed shaft and a right foot pedal, with the right foot pedal sleeved on the outside of the right fixed shaft; a flexible component is provided above the right foot pedal to prevent the user's foot from detaching from the right foot pedal. The elastic rope is fixed to the flexible component.
10. The foot-pedal exerciser according to claim 9, wherein: The outer ends of the left and right fixed shafts are equipped with plugs to prevent the left and right foot pedals from disengaging; flexible components are sleeved on both the left and right fixed shafts, and the flexible components can rotate by relying on the left and right fixed shafts.
