Description

Technical Field

[0001] This utility model relates to the field of rehabilitation equipment technology, and in particular to a quick-release foot pedal. Background Technology

[0002] Foot pedals are commonly found on rehabilitation equipment, especially lower limb rehabilitation equipment. Existing foot pedals are generally divided into fixed and adjustable types. Fixed foot pedals have a simple structure and good stability, but they are not well-suited for users of different heights. Existing adjustable foot pedals typically have several fixed positions. The movable pedal components are placed within frames of different heights, and then secured with hand-tightened screws or positioning pins to achieve height adjustment. However, the main drawback of existing adjustable foot pedals is the cumbersome adjustment process, requiring loosening the hand-tightened screws securing the foot pedal, adjusting it, and then tightening the screws again. If positioning pins are used instead of hand-tightened screws to adjust the height, the foot pedal becomes unstable.

[0003] In summary, existing fixed foot pedals cannot be height adjusted, while existing adjustable foot pedals have cumbersome adjustment procedures and insufficient stability after adjustment. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a quick-release foot pedal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-release foot pedal includes a fixed pedal and a movable pedal. The fixed pedal has a support hole, and the movable pedal has a support column at its bottom. The support column passes through the support hole and the fixed pedal and the movable pedal are detachably connected through a quick-release assembly. The quick-release assembly is located at the bottom of the fixed pedal and includes a rotating shaft located in the middle of the fixed pedal, a turntable rotating around the rotating shaft, and a transmission mechanism fixed on the turntable. The end of the transmission mechanism abuts against the support column.

[0007] Furthermore, the transmission mechanism includes an elastic connecting piece, one end of which is fixedly connected to the turntable, and the other end is connected to a top block, which abuts against the support column.

[0008] Furthermore, the transmission mechanism also includes a slider, one end of which is connected to the elastic connecting piece and the other end of which is connected to the top block, and slides in the guide block.

[0009] Furthermore, the turntable is connected to the elastic connecting piece by screws, and the top block is connected to the slider by studs.

[0010] Furthermore, the guide block is provided with a ball-head plunger, and the slider is provided with a countersunk hole. The ball-head plunger and the countersunk hole cooperate to fix the quick-release assembly.

[0011] Furthermore, the turntable is provided with a handle for rotating the turntable to quickly disassemble and install the fixed pedal and the movable pedal.

[0012] Furthermore, a limiting pin is provided at the bottom of the fixed pedal, and a limiting stop is provided on the side of the turntable opposite to the handle. When the handle is rotated, the limiting pin abuts against the limiting stop.

[0013] Furthermore, the fixed pedal also includes a fixed shaft connected to the main body of the rehabilitation equipment.

[0014] The advantages of this utility model are: the quick-release foot pedal uses a rotating shaft to drive the quick-release assembly to achieve one-click locking and one-click releasing, which simplifies the adjustment process while ensuring the stability of the pedal.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] like Figure 1 and Figure 2 As shown, a quick-release foot pedal includes a fixed pedal 1 and a movable pedal 2. The fixed pedal 1 has a support hole 11, and the movable pedal 2 has a support column 21 at its bottom. The support column 21 passes through the support hole 11, and the fixed pedal 1 and movable pedal 2 are detachably connected via a quick-release assembly. The quick-release assembly is located at the bottom of the fixed pedal 1 and includes a rotating shaft 5 located in the middle of the fixed pedal 1, a turntable 4 rotating around the rotating shaft 5, and a transmission mechanism fixed on the turntable 4. The end of the transmission mechanism abuts against the support column 21. This quick-release foot pedal consists of a fixed pedal 1 and a movable pedal 2. If the user is tall, the fixed pedal 1 can be used alone. If the user is short, the movable pedal 2 can be installed into the corresponding support hole of the fixed pedal 1 via the support column 21. Preferably, two support columns 21 and two support holes 11 are respectively arranged on both sides of the pedal. The turntable drives the transmission mechanism to abut against the support column 21, completing the quick fixing and disassembly of the movable pedal 2.

[0024] In one embodiment, such as Figure 2 and Figure 3As shown, the transmission mechanism includes an elastic connecting piece 6, one end of which is fixedly connected to the turntable 4, and the other end is connected to a top block 9, which abuts against the support column 21. For better abutment, the end of the top block 9 is semi-circular, matching the cylindrical shape of the support column 21. The rotation of the turntable 4 is transmitted through the elastic connecting piece 6, causing the top block 9 to rotate and abut or separate from the support column 21. When the elastic connecting piece 6 is compressed and deformed, the turntable 4 passes through the dead point (the point where the elastic connecting piece 6 generates the maximum deformation), locking the compressed support column 21. An additional opposite force is required to unlock it, thereby achieving the abutment or separation of the support column 21. In a preferred embodiment, the transmission mechanism further includes a slider 10, which is located between the elastic connecting piece 6 and the top block 9, with one end connected to the elastic connecting piece 6 and the other end connected to the top block 9, and slides in the guide block 12. The guide block 12 includes a square groove in which the slider 10 slides, guiding the top block 9. Specifically, the turntable 4 is connected to the elastic connecting piece 6 by screws, and the top block 9 is connected to the slider 10 by studs. The studs are used to adjust the clamping force of the top block 9 by adjusting the gap between the top block 9 and the slider 10.

[0025] In one embodiment, such as Figure 3 and Figure 4 As shown, the guide block 12 is provided with a ball-head plunger 13, and the slider 10 is provided with a countersunk hole. The ball-head plunger 13 cooperates with the countersunk hole to fix the quick-release assembly. In order to prevent the shaft 4 from rotating when the movable pedal 2 is not installed, a ball-head plunger 13 is installed on each of the two guide blocks 12. The ball head of the ball-head plunger 13 presses against the countersunk hole on the slider 10, which can fix the entire quick-release assembly and prevent the shaft from rotating.

[0026] To release the movable pedal 2 during use, simply turn the handle 8 clockwise. The sliders 10 on both sides will slide towards the center simultaneously, causing the top block 9 to leave the surface of the support column 21. At this point, the movable pedal 2 will be released and can be easily removed.

[0027] The quick-release foot pedal needs to be fixed to the rehabilitation equipment body in order to function. The quick-release foot pedal is connected to the rehabilitation equipment body through the fixed shaft 15 on the fixed pedal 1.
